INTRODUCTION RECONSOLIDATION OF THE CONTRA _COSTA COUNTY GENERAL PLAN, (County File: GP#04-0007). This is a reconsolidation of Contra Costa County General Plan. This action would cover the following changes to be made to the General Plan document: A. Incorporation of all adopted General Plan Amendments from the time of the last reconsolidation in 1996 through 2004 into the General Plan document. Among these General Plan Amendments to be incorporated into the General Plan document, include: an updated Housing Element adopted by the Board of Supervisors in 2001, and modifications to the Urban Limit Line adopted by the Board of Supervisors in 2000 and 2004. See Attachment "A" to this report for a comprehensive listing of General Plan Amendments (1990-2004) approved by the Board of Supervisors. B. Incorporation of demographic data based upon the 2000 Federal Census and related background into the text and tables in the General Plan document. C. Elimination of obsolete and outdated descriptive or explanatory text within the General Plan document. D. Elimination of policies and implementation measures in the text of the General Plan document related to lands that have been annexed to cities since 1996, or due to the incorporation of the City of Oakley in 1999. E. Elimination from the text of the General Plan document those projects that have been built or completed and whose elimination will simplify and keep the document current. F. Adjustment to the Land Use Element Plan Map to reflect city land use plans and planning decisions under comparable County General Plan designations. G. Adjustment to the Land Use Element Plan Map to reflect locations where since 1996 land area has been placed under public ownership (e.g. parkland or watershed) or where significant land area has been deed restricted for open space purposes. H. Incorporation of maps found throughout the General Plan document that have been prepared using the County's Geographic Information Systems (GIS) mapping program which improves the readability and detail of these maps. L Correction of errors and omissions in the text of the General Plan document since the last plan reconsolidation in 1996. The purpose of this action is to reconsolidate the County General Plan document. This action will neither add new policies nor change existing policies (with the exception of deleting obsolete explanatory text or obsolete policies for areas no longer under County jurisdiction or for projects that have been built or completed). The action is countywide in scope and will replace the existing County General Plan document. To differentiate this plan document from the existing document that is entitled " Contra Costa County General Plan 1995- 2010", the Reconsolidated Plan will be entitled "Contra Costa County General Plan 2005-2020". JURISDICTION OF THE COMMISSION While General Plan Amendments fall within the jurisdiction of all three Planning Commissions this matter is being brought to the County Planning Commission since this is a project that is countywide in scope as specified by the ordinance establishing the Commissions and the Board of Supervisors' implementation decisions. Sole jurisdiction to make a recommendation is vested with the County Planning Commission. This reconsolidation of the plan is procedural in nature and falls within the countywide scope of the County Planning Commission. CEQA A proposed Negative Declaration/Initial Study has been prepared for this project and was issued on December 6, 2004. The proposed Negative Declaration/Initial Study determined that this project involves an action that would reconsolidate the Contra Costa County General Plan document. The plan reconsolidation will neither add new policies nor change existing policies. Instead, its purpose is to incorporate into the plan document all adopted General Plan Amendments from the time of the last reconsolidation in 1996 through 2004, while also deleting obsolete and/or dated explanatory text, policies, implementation measures and maps, for those areas that are no longer under County jurisdiction,, or, for projects that have been built or completed since 1996. The proposed action will have no environmental effects,, either directly or indirectly. S-3 IV. HOW THE RECONSOLIDATED PLAN WAS PREPARED The overall approach by staff was to inventory the current General Plan to determine how a reconsolidated plan should be prepared. The General Plan Amendment files from 1996 to 2004, including text and maps, were collected and inventoried. The plan document was then reviewed, page by page, by staff to identify where the text or the maps in each chapter contained dated and obsolete information under six circumstances: 1) text or maps that refer to land area that had been annexed to a city since 1996; 2) text or maps that refer to land area that was part of the incorporation of the City of Oakley in 1999; 3) demographic data in tables or text that relies upon 1990 Federal Census, instead of the more recent 2000 Federal Census; 4) text or maps that refer to projects that have been built or completed; 5) text that is explanatory or descriptive (not policy or implementation) which is now outdated or obsolete; or, 6) text which contain typographical errors, is poorly worded, or presents incorrect facts. The Land Use Element Map and other related plan maps were then reviewed to identify where Board approved changes and changed circumstances, such as acquisitions by public agencies for parks or watershed land, LAFCO sphere of influence boundary changes or annexations, etc, should appropriately be reflected in an adjusted map. V. FORMAT OF THE RECONSOLIDATED PLAN TEXT The proposed reconsolidated General Plan document, including text and maps, has been reproduced in its entirety (see attached document). The plan text shown in regular typeface reflects the plan as currently adopted by the Board of Supervisors. This includes all the text amendments already adopted by the Board of Supervisors. For example, the Housing Element adopted in December 2001 is incorporated as existing plan text. The suggestions by staff to further modify the text for clarity or to eliminate obsolete, incorrect, or outdated references are handled in two ways. First, proposed deletions are shown with a line through the word or sentence. (e.g. not }. Second, new wording is underlined. Second, policies and implementation measures have been renumbered and reordered to reflect proposed changes and deletions. V1. FORMAT OF THE RECONSOLIDATED PLAN FIGURES The existing General Plan document contains figures in both letter size (found through out the document) and special foldout maps (11"x 17"). It is noted, that the cost for the reproduction of the foldout map is now expensive and the use of fold out maps complicates creating the plan document in a CD-ROM format. Therefore, except in three cases,, under this reconsolidated plan document figures S-4 within the body of the plan have been created only in a letter size (8 1/2x 11") format. They have been prepared with a common border format on a new County base map. Where possible the GIS mapping program has been used to add detail and precision to these maps. Policy related information on these maps has not been modified in the unincorporated areas. Attached to the plan (or on the CD-ROM) are the three oversized maps that are a functional part of the existing plan. The County Roadway Network Plan and the 65/35 Contra Costa County Land Preservation Map are reproduced on 11" x 17" maps. These two maps reflect changes adopted since the last plan reconsolidation in 1996. The color Land Use Element Map is attached on a map at approximately scale of 1:36,700. All three maps are also included in the CD-ROM as PDF file attachments. The Land Use Element Map has been adjusted in three basic ways. First, a.. General Plan Amendments adopted since 1996 have been incorporated into the map. Second, public acquisitions of land for park, watershed, recreation, or public use have been incorporated into the map. Third, an effort has been made to incorporate within city limit boundaries the current city planning policies and decisions (City General Plans) based upon comparable or nearest County General Plan designations. This will bring the County's Land Use Element Plan Map into more harmony with those of the 19 cities in the County than is currently reflected on the existing Land Use Element Plan Map. Lastly, where the County's approval of land use decisions since 1996, such as a General Plan Amendment, Subdivision Map, or Development Plan, have created a more precise boundary between land uses, the more precise boundary is now reflected on the adjusted Land Use Element Plan Map. V11. SUMMARY OF PLAN RECONSOLIDATION BY CHAPTER OR ELEMENT The following is an overview of proposed plan reconsolidation relating to text, tables, and maps for each chapter in the General Plan: Chapter I INTRODUCTION The primary text changes in Chapter 1 are related to clarification and/or correction of factual information. Chapter 2 PLANNING FRAMEWORK Information related to the law establishing LAFCO and the Sphere of Influence map were both corrected to reflect changes since 1996. Demographic data taken from the 2000 Federal Census has been incorporated into the section on Social and Economic setting S-5 to reflect the most current U.S. Census data from, and to show the rate of growth for certain data between 1990 and 2000. In addition, editorial changes deleting some portions of the Social and Economic section were made to make the document more current. Chapter 3 LAND USE ELEMENT New text has been added to reflect policies and implementation measures for projects that have been approved through General Plan Amendments since the last plan reconsolidation in 1996. References to projects that have been built or have been completed are proposed for deletion since these policies have served their original purposes (NOTE: After a policy is proposed for deletion, there is a shaded notation as to why the policy is proposed to be deleted). Reference to policies and implementation measures inside for land area that is now within city boundaries due to annexation or incorporation have been proposed for deletion due to loss of County jurisdictional control. Background demographic data based on the 2000 Census have been incorporated, and, as necessary, editorial changes to the text have been made through out Chapter 3 to reflect this demographic data. All of the maps in Chapter 3 have been done over again using the GIS mapping program to better reflect changed circumstances since 1996 (e.g. General Plan Amendments) and to improve readability and detail of these maps. Chgpter 4 GROWTH MANAGEMENT ELEMENT Clarification and minor editorial changes have been made. The list and map of Contra Costa Transportation Authority's (CCTA) Routes of Regional Significance have been deleted and replaced with new Table 4-3, Routes of Regional Significance and Figure 4-3: Map of Routes of Regional Significance that reflect the current Routes of Regional Significance adopted by CCTA. S-6 Chapter 5 TRANSPORTATION AND CIRCULATION ELEMENT Clarifications and minor editorial changes have been made. Tables 5-1,, Major Roadway and Transportation Improvement and 5-2, Year 2005 Demand For Additional Park and Ride Lot Spaces contained obsolete and dated cost estimates and park and ride spaces data(each table circa 1990) and are proposed for deletion. Policies to encourage the state and regional development of inner- city rail services have been added to the text, based on action in April 9, 2001 by the Board of Supervisors. These policies are advisory to state and regional agencies responsible for intercity rail. Chapter f HOUSING ELEMENT The Housing Element that was adopted in December 2001 is incorporated in its entirety under this plan reconsolidation (replacing the previously adopted Housing Element). Chqpter 7 PUBLIC FACILITIES/SERVICES ELEMENT Out of date background or explanatory text for water and sewer services were removed. Statistical data and tables were corrected. Maps were corrected to reflect current jurisdictional boundaries (e.g. water and sewer district boundaries). Figure 7-7, Solid Waste and Disposal Facilities and 7-8, Figure, Commercial Hazardous Waste Facilities, in the Public Facilities/Service Element were corrected to reflect the most current permitted facilities Cha-oter 8 CONSERVATION ELEMENT Table 8-2 was corrected to reflect current status of special status species. Given the complexity of this table an entirely new Table 8-2 is provided, with the existing Table 8-2 provided in strike out version. Clarification and minor editorial changes were made. S-7 Table 8-5, an inventory of air pollutant emissions, and Figure 8-6, Air Quality, are proposed for deletion since they have no policy basis and contain obsolete data(circa 1989-90). Chapter 9 OPEN SPACE ELEMENT Minor editorial changes and clarifications were made. Where parks have been acquired and developed since 1996, the mapping of park facilities in the Open Space Element, at Figure 9- 3, Major Parks and Open Space Areas, and at Figure 9-4, Local Parks, Open Space Element,have been corrected. Chapter 10 SAFETY ELEMENT Minor editorial changes and clarifications were made. Figure 10-2, Mapped Earthquake Faults was corrected to reflect correct locations of faults, etc. Chapter 11 NOISE ELEMENT Only minor editorial changes and clarifications were made Table 11-2, Daytime Existing Noise Levels From Industrial Sources (8/1/90) was deleted because all reference locations are now in city boundaries (e.g.. City of Oakley). Chapter 12 GLOSSARY AND ABBREVIATIONS No changes were made. APPENDICIES The appendix related to the Housing Element (2001) was incorporated into this section of the plan document. VIII. GIS MAPPING O►F FUTURE LAND► USE ELEMENT PLAN MAP MODIFICATIONS The GIS mapping program now enables the Community Development Department to maintain the Land Use Element Plan Map in a manner that can more accurately reflect actions associated with the dedication of land area for parklands and open space, and the deeding of development rights for habitat and open space protection. In the past it would take several years before the Land Use Element Plan Map would catch up to the land acquisitions by East Bay Regional S-8 Park District for parklands or land acquisitions by East Bay Municipal Utility District for watershed. The deeding of development rights for habitat and open space protection on significant tracts of land in the unincorporated area has also been occurring over the past several years, and it would normally take some years before such changes would then be reflected on the Land Use Element Plan Map. The GIS mapping program is also particularly useful in recisin p g the boundaries between land use designations. There are occasions when in the course of reviewing an application the boundary between land use designations (as depicted on the Land Use Element Plan Map) is unclear and could be better defined. In such instances involving minor boundary questions, the GIS mapping program can be used to more precisely establish the boundary between land use designation in consultation and concurrence with the affected landowner(s). These abovementioned changes to the map do not have policy implications, but could be described as "housekeeping". These are corrections and adjustments that involve a change in property ownership from the private sector to the public sector for a public purpose, or a change in private property's status where the development rights have been deeded to the County (or some other entity) typically to protect habitat, or to better precise the boundary between land use designations. It would be possible to institute a program to monitor and regularly report to the County Planning Commission on the non-substantive ("housekeeping") corrections/adjustments to the Land Use Element Plan Map for review and recommendation to the Board of Supervisors to adopt such map corrections/adjustments. IX. RECOMMENDATIONS Recommend the Board of Supervisors take the following actions: A. Recommend the adoption of the Reconsolidation of the Contra Costa County General Plan (2005-2020), as presented. The recommended adoption will eliminate all the strikeout proposalq and will include all the underlined additions and corrections. It will also include the three oversized maps attached to the plan. Such adoption would supersede all prior General Plan documents. B. Recommend instituting a program whereby non-substantive corrections or adjustments to the Land Use Element Plan Map are regularly brought to the County Planning Commission for review and recommendation to the Board of Supervisors to adopt such map corrections/adjustments.

The goals,policies and implementation programs contained in the General Plan represent the hopes and concerns of the residents of the County in terms of defining and preserving a"quality of life." The various elements or chapters of the plan are intended to provide objectives,principles and standards to decision-making bodies in the County,as well as numerous other public agencies,that will be making decisions about the development of private and public lands and the locations and extent of infrastructure improvements such as sewers and roadways. Although a General Plan is primarily concerned with the physical development of property,the consequences of a plan's growth policies also impact the social fabric of a community. For example,if a General Plan allows the development of an industrial or business park in a specific location,more jobs may eventually become available to local residents. Similarly,if a plan designates a park or other public facility,or if a program encourages the construction of affordable housing,the policy will have a social and economic impact upon the quality of life in those affected locations. 1.2 PUBLIC PARTICIPATION IN GENERAL PLAN PROCESS Preparation of the General Plan X90-X4}52005-2020 involved a unique and extensive process of public participation and outreach. In early 1986,the County Board of Supervisors established a General Plan Congress to advise the County staff on how to revise the County's General Plan. The 67-member General Plan Congress represented abroad range of interests in the County,including the City Councils from each of the 18 cities in the County,County service districts,environmental groups,landowners,developers,and public interest groups including the League of Women Voters,Citizens for a Better Contra Costa,Sierra Club,Audubon Society,and the Greenbelt Alliance. The General Plan Congress met monthly from July 1986 through January 1989. In addition, each Congress member sat on one of three subcommittees:Agriculture and Open Space,Infrastructure and Jobs/Housing Balance. These subcommittees met on a weekly or biweekly basis to take public comment,debate important issues and develop reports and position papers for the entire Congress. The subcommittees kept lists of the public attendance at the meetings,and advised those attendees of the meeting times by mail. With the help of the General Plan Congress,the County prepared a draft General Plan in November 1988. After recommending additional changes to that draft,the Congress voted to pass the draft General Plan onto the Community Development Department staff and Planning Commission without recommendation,and to disband. In March 1989,the County made available for public review and hearing a draft of the General Plan. Between March 1989 and August 1990, the County Board of Supervisors held numerous public hearings and received extensive written comments on the March 1989 draft. All segments of the Contra Costa County population participated in that public comment period, including representatives of ranchers, developers, farmers, environmentalists,labor groups,cities,special districts,business and industrial associations. In mme to the public comments received,the County then prepared a revised and updateddraft of the General Plan,which was made available for additional public comment and review in October 1990. Between October and December 1990,the County Pbming Commission and Board of Supervisors held public hearings on the October 1990 draft As a result of those comments and the pa&sage on November 6,1990 of Measure C,the 65/35 Contra Costa County Land Preservation Plan (described below),the County again revised the document resulting in the Contra Costa County General Plan 1990-2005. 1-1 1.Introduction 1.3 PUBLIC PARTICIPATION THROUGH VOTING PROCESS In addition to the extensive public participation and input process through which this General Plan evolved,the voters of the County also influenced various aspects of this General Plan through the referendum process. Two initiative measures in particular have and will continue to impact the physical development of the County during the horizon of this General Plan. These two measures, "the Revised Contra Costa Transportation Improvement and Growth Management Program"adopted on August 3. 1988("Measure C 1988"),and"Me 65/35 Contra Costa County Land Preservation Plan" adopted on November 6, 1990 ("Measure C - 1990"), expressed voters' concerns, goals, and principles relating to a vision of long-term growth in Contra Costa County. The policies and principles expressed by the voters in Measure C-1988 and Measure C-1990 have guided the evolution of most of the elements of this General Plan. Generally speaking, these two measures guided the preparation and completion of this General Plan in such areas as growth management,land use,transportation and circulation,housing, public facilities and services,and conservation and open space issues. To underscore the importance these measures have had on the General Plan process cutting in the adoption of this General Plan and in the interest of making this constitution of land use document more meaningful for the public,the text of Measure C-1988 and Measure C-1990 is set forth in its entirety in Section 1.10 of this Introduction section. Where appropriate or required,provisions of these two measures have been integrated throughout the various elements of this General Plan. The approval by the voters of Measure C-1988 in 1988 was a major factor in the creation and establishment of the scope of the Growth Management Element found in this General Plan. Measure C - 1988 requires that the County and other jurisdictions must adopt a Growth Management Element in accordance with various terms of the measure in order to receive local street maintenance and improvement funds. The influence of Measure C-1988 is reflected throughout this General Plan since the Growth Management Element has necessarily been correlated with the other elements in this General Plan. In to responsibly listening and responding to the concerns and hopes of the public expressed through the General Plan Congress,including thousands ofhours ofpublic meetings and hearings,the Board of Supervisors placed Measure C-1990 on the ballot prior to the completion ofthis comprehensive General Plan process.Through this initiative measure,the voters 20 key policies concerning open space and agricultural PiN creafion ofanUrbanLirrit Line, ofppen hillsicks and abaft significant ridge lines,,growth--- fforclable housingand other issues which the CoLmtyhad been to adbetas part of its General Plan The success of this measure evidenced the broad support for these policies. In Ation,as part of this successful Board of Supervisors!initiated measure,the voters a 65/35 land stand which limits urban development in the County to no more than 35 percent ofthe land in the County and requires that at least 65 percent ofall land in the County be preserved for agriculture,open space,wedands,parks and other non-urban uses. Following this mandate of the voters,,the Board proceeded to reflect the Measure C-1990 policy in this General Plan. anc 1.4 LAN RECONSOLIDATIONS This-The Contra Costa County General Plan 1995-2010 iswas an updated version of the plan prepared by the General Plan Congress. It .11..&S beenwas modified to reflect all plan amendments adopted -c4rw-e,7-between the. General Plan Congress' work and January 1995. It also correcteds,some errors or inconsistencies found in the 1990-2005 version of the plan and updates certain facts.. This second reconsolidation entitled ContraCosta County General Plan 200-25-2020 includes all plan amendments since 1995 includinp ,a totally revised Housing Element, and Urban Limit Line amendments. It also corrects facts and niqps. It eliminates extraneous and dated textual material and obsolete maps. Lastly,it adiusts the Land Use Plan Ma p to reflect park and open apace acquisitions', and better reflects cit:general 121an p licies within incorporated areas. 1.5 LEGAL AUTHORITY State law,specifically Sections 65300 through 65403 of the California Government Code,mandates that all cities and counties prepare and adopt a comprehensive,long-term,and internally consistent General Plan to guide the future physical development of their jurisdictions. According to recent court decisions clarifying the intent of the State legislation, the role of each community's General Plan is to act as a "charter" for development; it is the foundation upon which all land use decisions are to be based. 1-2 1.Introduction At one time, local General Plans were looked upon as a set of broad policies that had small roles in development decisions. However,changes in State law since the original statutes were adopted in the 1950's have vastly boosted the e of the General Plan in local decision-making. A General Plan must now provide more concrete direction for land use and facility approvals,while providing flexibility for balancing necessarily competing goals and policies. State law requires that once a local government has adopted its General Plan,local officials must implement it. The Government Code provides general direction to the planning agency for implementing the overall plan,but requires that more specific implementation programs be adopted for some of the individual portions of the plan, such as the Housing and Open Space Elements. The most commonly recognized form of implementation is the zoning ordinance, which specifies exact development standards (types of uses allowed, building heights and setbacks,etc.)for the various zones or districts within a jurisdiction. Accordingly,State law requires that the zoning and subdivision ordinances for almost all jurisdictions in California must be consistent with the adopted General Plan(Section 65860). In addition,the following city or county land use approvals must be consistent with its General Plan: all subdivisions,rezonings,specific plans,capital improvementPrograms,redevelopment plans,development agreements,park dedication ordinances,agricultural preserve contracts,housing authority projects,local coastal plans,and several other specific approvals. Although not specifically required by State statute,a 1984 Appellate Court decision also held that the approval of all use permit applications must be consistent with the local General Plan.Thus,recent State legislation and court decisions effectively make most implementing ordinances used by local jurisdictions in day-to-day land use decision-niaking subservient or secondary,to General Plan policies and maps. L6 COMPONENTS OF THE GENERAL PLAN California statutes require that all cities and counties prepare and adopt a General Plan that contains the following seven mandatory"Elements"or subject categories: Land Use Element, This Element describes the general distribution and intensity of uses of land for housing,business,industry,open space,public facilities,etc.,with accompanying maps. Circulation Element. This Element identifies the location and extent of existing and proposed streets, arterials,highways,transportation routes and terminals,and other related facilities. Housing Element. This Element contains a comprehensive assessment of current and projected housing needs for all segments of the community,a list of policies to meet the needs,and an inventory of specific action programs to Imp* lement the policies. Conservation Element. This Element addresses the conservation, development, and use of natural resources such as water,forests,soils,rivers,and mineral deposits. Open Svace Element. This Element details plans and measures for preserving open space areas in order to manage the production of resources,to provide outdoor recreation.,to preserve the public health and safety,and to identify important agricultural lands. Safety Element. This Element establishes policies and programs to protect the community from risks associated with seismic,geologic,flooding,wildfire,and other hazards. Noise Element. This Element identifies noise problems in the jurisdiction; defines standards and mitigation measures;and provides coordination with land use policies. The degree of detail to winch each issue is discussed in the plan depends upon local conditions and its relative perceived importance. In addition to the seven element categories listed above,State law encourages local jurisdictions to prepare and adopt any other elements or address any other issues mane to the jurisdiction's physical development. 1-3 --Now 1.Introduction ofto The Contra Costa County General Plan includes the seven mandated elements. The plan also includes two optional elements, namely,a Public Facilities and Services ElerYxent and a Growth Managerrmt Element For ease of discussion,the Public 104MMO Facilities Element contains some ofthe components ofthe other statutory elwmts. The plan is or, as Chapter 1: Introduction Chapter 2: Planning Framework Chapter 3: Land Use Element (Includes all Countywide land use goals,policies,and implementation measures,as well Osumi% as more detailed land use policies applied to specific unincorporated areas. As referenced in the Land Use Element,many of the remaining required components of this Element are contained in the Public Facilities/Services Element.) Chapter 4: Growth Management Element (Includes a Growth Management Program and policies from Measure C-1988.) Chapter 5: Transportation and Circulation Element (Includes goals and policies regarding major thoroughfares,railroad and transit routes, terminals,and other local public transportation systems.) Chapter 6: Housing Element (Includes goals and policies regarding programs, improvements, development and preservation of housing needs to meet all economic sectors of the community.) Chapter 7: Public Facilities/Services Element (Includes policies regarding water and sewer service; flood control; landfills; public buildings;police and fire protection;solid and hazardous waste management;schools; childcare;and other public facilities.) Chapter 8: Open Space Element (Includes overall goals and policies for the County, as well as policies reg scenic resources;historic/cultural resources;the 65/35 preservation standard and parks and recrtation.) Chapter 9: Conservation Element (Includes overall goals and policies for the County, as well as policies regarding vegetation and wildlife; agricultural resources; renewable energy resources; mineral, soil,and oil and gas resources;water resources;harbors;and air resources.) Chapter 10: Safety Element (Includes goals and policies regarding the protection of the community from seismic and geological hazards and other natural disasters.) Chapter 11: Noise Element (Includes goals and policies regarding noise levels and sources that are used in setting land use policies and for developing and enforcing a local noise ordinance.) INTERNAL CONSISTENCY State planning law requires that all parts of the General Plan comprise an integrated, internally consistent and compatible statement ofpolicies. These standards imply that: 1)all elements of the General Plan have equal legal status; 2) all goals, objectives, policies, principles, standards and plan proposals in the General Plan must be *mom internally consistent;and 3)any implementation programs set out in the plan must follow logically from the plan's 14 1.Introduction goals and policies. Hence,each chapter of the General Plan clearly states its legal authority,relationship to other elements,relationship to other General Plan documents,and its organization. L7 DEFINITION OF MAPS,GOALS,POLICIES,AND IMPLEMENTATION MEASURES The California Government Code states that"the General Plan shall consist of a statement of development policies and shall include a diagram or diagrams and text setting forth objectives,principles,standards,and plan proposals"(Section 65302). The purpose of this section is to define these terms in the context of this General Plan. GENERAL PLAN DIAGRAMS(MAPS) The diagrams that are required in a General Plan under the State law have been defined as graphic expressions of the plan's development policies. However,there is a debate among planners and lawyers alike about how detailed or general the maps(and text)should be in a General Plan. The diagram or maps in a General Plan need not be as detailed as other regulatory maps,such as zoning maps,but they should be detailed enough so that the users of the plan, after reviewing all other pertinent maps and portions of this plan, can reach the same general conclusion regarding the appropriate use of any parcel of land at a particular phase of a city's or county's physical development. In many instances, a specific parcel may be located in more than one General Plan land use designation, since these designations tend to follow natural features of the land,which are not always contiguous with property lines. For a large vacant parcel,the hilly,unbuildable portion of the site may be designated for open space uses,while the flat areas may be designated for housing or commercial uses. Similarly,portions ofparcels,may be located in or outside the Urban Limit Line. Decision makers should be able to use the General Plan,including its diagrams or maps,in coordinating day-to-day land use and infrastructure decisions. At the same time,given the long-range nature of a General Plan,its text and maps should be general enough to allow a degree of flexibility in decision making as conditions change. For example, a General Plan may recognize the need and desirability of a community park in a proposed residential area,but the precise location of the park may not be known when the plan is adopted. The plan does not need to pinpoint the location,but it should include a generalized designation on the diagram showing the general location,along with policies indicating that the park site will be selected and reserved when the area is developed.' GOALS A goal statement sets the direction for more specific policies and implementation programs. A goal is an ideal future end, condition,or state which is related to the public health,safety,or general welfare toward which planning measures are directed. A goal is a general expression of corrunmity values and,therefore,is abstract. Consequently,a goal is generally f%*%+; t2 not le,time dependent or suggestive of specific actions for its achievernen POLICIES A policy is a specific sit" intended to guide decision making Policies are based upon General Plan goals and are arrived at A A-!-__ 0 through planning experience,studies,and anuumpm4willofthe best available and information at a particular point in time.

As a constitution-Me document the policies in this General Plan are intended to guide decision makers through this difficult N&ncing process. At the General Plan level,polices are not static as ironclad regulations. The policies expressed in this General Plan were based on the best available information at the time the Plan was prepared.New and better 1 11 fi� �mfion will necessarilybe--re ted toffieckcisionnmkemdufing&effeofffiisPL,tn,ffimfomreW*=* gffi4asanevolufionmydocwmtffiepohcies expressed in this General Plan will be evaluated in light of this new and better mformation and,where necessary,policies will be updated 1-5 1.Introduction fftp_; While cautioning the reader of this General Plan document against myopically focusing on a particular policy without reference to its harmonized context it is important that certain of these guiding policies be expressed with stronger levels of commitment than others. When considering policies in this General Plan,the use of the word"shall"indicates more AAM=W directive than the use of the word"should." While there are occasions where.a proper balancing of the hundreds of policies contained in this document when viewed as an integrated whole, would not wan-ant strict adherence to a particular policy, the level of compelling or countervailing policies would appropriately be less to offset competing .00-. policies using the word"should,"than to offset a policy or policies using the word"shall." IMPLEMENTATION MEASURES An implementation measure is a specific action,procedure,program,or technique that carries out a General Plan policy. The most obvious example of an implementation measure is a jurisdiction's zoning ordinance. Often, implementation measures cited in a General Plan will consist of a list of specific programs that should be carried out after the plan is adopted. When a plan is updated,a careful review of the list of previously adopted implementation measures can indicate how realistic and effective the plan has been during the previous years. 1.8 THE DIFFERENCE BETWEEN ZONING AND GENERAL PLAN DESIGNATIONS One of the most common misunderstandings about General Plans in California is their relationship to adopted zoning ordinances. As the previous discussion has already indicated,zoning is the implementation of a General Plan and it must be consistent with General Plan policies and land use designations for specific properties. In simple language,this means that zoning is secondary or subservient to the General Plan;in the event of a conflict the General Plan is followed. Unfortunately,due to staffing limitations and community opposition,a zoning ordinance will often not be revised to be made consistent with the new General Plan(or General Plan Amendment(GPA)),which causes confusion to members of the public for years to come. Thur. iticuitsill th A AJL%*%Jll oun!y staff has initiated a program to begin the systematic review and revision of zoning andother ordinances,biew S.1.7 LJ4.".L&A1L&1LJL1L&%e%.%A"&%0AL.7 "A.J6WF%JMYL& NAWL&WL40114&Affilllalt VZOMIgJNO_MZ � 110W accom dished in NorthRichmond.Bay Point,and undenyray in Rodeo.. This These actions will ensure that the 4:3--muly ordinances governing day-to-day land use decisions do not conflict With adopted plan policies. 119 HOW TO USE THE GENERAL PLAN The General Plan includes maps in each Element,as well as accompanying text that lays out goals,policies,and implementation measures grouped around specific issues. Thus,if a property owner or other member of the public wants to know what General Plan policies might apply to a specific property,he or she can begin by examining the Land Use Element map to determine what land use designation is applied to the property(e.g.,"Single Family Residential-Low Density," "Commercial,"etc.). The owner should use the land use map in conjunction with the other maps within the plan(e.g.,the flooding and seismic hazard maps), as well as note the interplay with other element's specific written goals, policies, and implementation lementation measures(e.g.,growth management},to determine whether a development proposal for a particular site is fully consistent with the County General Plan. As an example only,the property owner would follow the steps outlined below to find the naps and policy language in the Land Use and other General Plan Elements which could affect development or redevelopment of the property: 1) Examine the Land Use Element map to determine the land use designation for the property and the --- location of the Urban Limit Line. 2) Check the maps and text in the other General Plan Elements,especially the Open Space,Conservation and swam Safety Elements, to see if the property is located within or adjacent to some type of resource or hazard 1-6 1.Introduction area (e.g., a "significant ecological resources area," a flood hazard area, an area of high liquefaction potential,etc.)or has slopes over 26 percent grade subject to hillside protection policies. 3) Read the general goals and policies in the Land Use Element, the provisions of the County's Growth Management Program(Chapter 4), and other relevant Elements as cross-referenced in each Chapter's subheading "Relationship to other General Plan Elements," to determine how they might affect development or redevelopment of the area in which the property is located. 4) Check Chapter 3 to determine ifany detailed policies or development standards apply to the area in which the PR4=1 LY is located(e.g,if the property is located in Crockett,read the section entitled"Policies for the Crockett Area!'). 5) If the property is located in a rural area,check whether public facilities such as water or sewer serve the area and read the relevant parts of the Public Facilities/Services Element. 6) Check the general goals and policies in the Land Use Elements and the Open Space Element to understand the potential limitations presented by the 65/35 Land Preservation Standard. Note that the above sequence of examination is an example of what may be the bare minimum that should be followed and is probably not sufficient in many instances. Depending on the specific location or characteristic of the area or property,several other steps should be added so that other portions of the General Plan are consulted. For example,if the property is located adjacent to a known noise generator,such as a highway or heavy industrial area,the Noise Element should be examined to determine whether the property is included within a mapped noise "contour" line of a certain level. If it is located within a specific noise contour, General Plan policies in that element direct that noise impacts affecting new development on the property must be properly mitigated. A thorough reading of the General Plan text and maps is advisable. Similarly, if a proposed project is located on a property that is crossed by a riparian vegetation or a creek,the specific policies that apply to the preservation and maintenance of creeks and adjacent lands must be consulted in the appropriate section of the Open Space or Conservation Element. 1.10 THE GENERAL PLAN AMENDMENT PROCESS State law stresses that a General Plan can no longer be viewed as a static,"end state"document but must adequately address the changing issues and policies of a jurisdiction during the designated"planning period." Thus,a process for considering amendments to the plan must be available to reflect changing conditions and conununity values. Amendments to the plan can be initiated by the County(through the Planning Commission or Board of Supervisors)or requested by private individuals. A typical General Plan amendment("GPA")involves changing a land use designation on a property or series of properties to allow urban development of what was previously agricultural lands within the Urban Limit Line,or to allow development of a different use or density than what is permitted under the existing plan. For example,a typical GPA will request a change in designation for a group of'properties within the Urban Limit Line from"Agricultural Lands"to "Single Family Residential-High Density,"or from a"Single FwW' designation to a "Multiple Family"category. A GPA may also involve the reclassification of a roadway from a"collector"to an"arterial." In accordance with Measure C - 1990, no General Plan amendment can change the 65/35 Land Preservation standard without a vote of the people by initiative. This standard limits urban development in the County to no more than 35 percent of the land in the County and preserves at least 65 percent of all land in the County for agriculture,open space,wetlands,parks and other non-urban uses. State law generally limits the number of amendments to any mandatory element of ajurisdictioWs plan to four each calendar year(Government Code Section 65358(a). However,State law does not limit the number of individual requests which can be packaged into each of the adopted General Plan Amendments. 1-7 1.Introduction When a request for a GPA is received by the County from a private indivi"staff forwards the request to the Board of Supervisors with a reconij- lion on whether to proceed with a study of the application. After the Board authorizes the GPA study,staff collects the appropriate application fees and prepares an environnxntal evaluation of the proposal as required by the California Environmental Quality Act. After the envfiumiental docmientation has been prepared,staffanalyzes the request and astaff The GPA request is then scheduled for a public hearing at the appropriate planning can mnission (i.e.,County Planning Commission,East County Regional Planning Cmmiissim San Ramon Valley Area Planning Cbrnmi&4on). ONO- After receiving public testimony,the commission votes to recomtt-w-nd approval,denial,or nxxhfication of the request. The recommendation is then sent to the Board of Supervisors for another public hearing and a final decision. Each GPA request must be carefully weighed as to its consistency with the adopted goals and policies of the existing General Plan. In reviewing proposals for GPA's, officials should remember that the General Plan is a policy document for the entire community and that it may only be amended"in the public interest"(Government Code Section 65358(a)). Every adopted GPA must be consistent with the rest of the plan and appropriate changes need to be made to maintain consistency. 1.11 THE TEXT OF MEASURE C-1988 AND MEASURE C- 1990 -- MEASURE C-1988 CONTRA COSTA TRANSPORTATION IMPROVEMENT AND GROWTH MANAGEMENT PROGRAM -loft" Contra Costa Transportation Partnership Commission,adopted August 3, 1988 MEMBER JURISDICTIONS: Cities of Antioch,Brentwood,Clayton,Concord,El Cerrito,Hercules,Lafayette,Martinez,Orinda, Pinole,Pittsburg,Pleasant Hill,Richmond,San Pablo,San Ramon,Walnut Creek,Towns of Danville and Moraga,and the County of Contra Costa.

The Commission's principles are as follows: 1 A balanced transportation network of highways,local streets,public transit,growth management and regional planning are necessary to preserve the quality of life and a healthy viable economy for Contra Costa residents. 2. Public input,through both the Citizen Advisory Committee and the Regional Transportation Planning Committees,is a critical element of a successful comprehensive transportation and growth management process to reduce traffic congestion. 3. State and Federal monies are insufficient to meet Contra Costa's transportation needs. A local retail transactions and use tax increase for transportation improvements is the only funding method available to local jurisdictions. 4. The Transportation Improvement and Growth Management Expenditure Plan is focused on alleviating existing traffic congestion through funding major regional projects and the establishment of a transportation and growth management process. 5. Transportation planning and growth management are needed to assure that new growth pays for the facilities required to meet the demands resulting from that growth. A cooperative planning process will be established on a countywide basis,while maintaining local authority over land use decisions and the establishment of performance standards,exclusive of operating budgets. 6. A complementary,but separate ballot measure,will provide for the acquisition and preservation of open space. These principles are the basis of the Expenditure Plan which is presented by the Commission, its Citizen Advisory Committee, Regional Transportation Planning Committees and Technical Stafffor approval by local jurisdictions and the voters of Contra Costa.

Reelonal Transportation Planning and Growth Management Develop a countywide Comprehensive Transportation Plan and computer model and update it every two years,provide technical support for the Regional Transportation Planning Committees,and conduct transportation and growth management studies. The Authority shall annually budget a percentage of the net tax revenue for regional transportation and growth management purposes. EXPENDITURE PLAN GROWTH MANAGEMENT PROGRAM To Be Met By Local Jurisdictions For Receipt Of Local Street Maintenance and Improvements Funding Introduction The overall goal of the Growth Management Program is to achieve a cooperative process for Growth Management on a countywide basis,while maintaining local authority over land use decisions and the establishment of performance standards. The transportation retail transactions and use tax is intended to alleviate existing major regional transportation problems. Growth management is needed to assure that future residential,business and commercial growth pays for the facilities required to meet the demands resulting from that growth. It is the intent of the Transportation Authority to create a process that results in the maintenance of the quality of life in Contra Costa. Local Street Maintenance and Improvements Portions of the monies received from the retail transactions and use tax will be returned to the local jurisdictions(the cities and the county)for use on local,subregional and/or regional transportation improvements and maintenance projects.Receipt ofall such funds requires compliance with the Growth Management Program described below. The funds are to be distributed on a formula based on population and road miles. Allocation of Funds The Authority will annually review and allocate funds to cities and the county. In allocating funds,the Authority shall make findings based on a statement of compliance regarding the Growth Management Program To receive local street maintenance and improvement funds from the Authority,each jurisdiction shall submit a statement of compliance with the Growth Management Program. Jurisdictions may use funds allocated under this provision to comply with these administrative requirements. The Authority will review this statement and make findings regarding the jurisdiction's efforts. If the jurisdiction's efforts are found satisfactory,the jurisdiction will be allocated its share of local street maintenance and improvement funding. Because of the great variation among the jurisdictions,it is expected that the Authority will need some flexibility in determining compliance with the Growth Management Program. Generally,this flexibility may take the form ofthe Authority setting deadlines for achieving one or more requirements as a condition of receiving local street maintenance and improvement funds. Growth Management Program To receive its local street maintenance and improvement funds,each jurisdiction must: 1 Adopt a Growth Management Element Each jurisdiction is to develop a Growth M Element of its General Plan to be applied in the development review process.7be element mil include Sections 2 and 3 below,aril jurisdictions must comply with Sections 4-8 below.The Authority and the Regional Thmsportation Planning Committees shalljointly prepare a model element and a I iftuishi-ativeproceduresto guide the local jurisdictions. Local jurisdictions shall develop their Growth Management Element within one year after receipt of the Authoritys model element 2. Adopt Traffic Level of Service(LOS)Standards Keyed to Ty2es of Land Use 0 Rural—LOS low-C(70 to 74)Volume to Capacity(V/C) Ono* 0 Send-Rural—LOS high-C(75 to 79)V/C 0 Suburban—LOS low-D(80 to 84)V/C 0 Urban—LOS high-D(85 to 89)V/C 1-12 1.Introduction 0 Central Business District—LOS low-E(90 to 94)V/C Based on the categories established above,each jurisdiction shall determined how the Traffic Service standards are to be applied to their General Plan land use and circulation elements,and the land areas to be defined as Rural,Semi-Rural, Suburban,Urban,and Central Business District(as suggested in the Guidelines in Appendix A). Each jurisdiction shall comply with the adopted standards. Jurisdictions may adopt more stringent standards without penalty. Level of Service(LOS)would be measured by Circular 212 or the method described in the most commonly used version of the Highway Capacity Manual. Any issues with respect to the application of the Highway Capacity Manual or rrxasummt of level of service shall be referred to the Authority's Technical Coordinating Convifittee for review and recommendation to the Authority.In the event that an intersection(s)exceeds the applicable Traffic Service standard,the Authority shall,jointly with local jurisdictions, establish appropriate mitigation measures or determine that a given intersection is subject to a finding of special circumstances. Any intersection that presently exceeds the Traffic Service standards and which will be brought into compliance in the most current Five Year Capital Improvement Program(see Section 6)shall be considered to be in compliance with the applicable standard. The Authority,jointly,with affected local jurisdictions,shall determine and periodically review the application ofTraffic Service Standards on routes of regional significance. The review will take into account traffic originating outside of the county or jurisdiction,and environmental and financial considerations. Local jurisdictions,through the forum provided by the Authority, shall jointly determine the appropriate measures and programs for mitigation of regional traffic impacts(see Section 5). Capital projects necessary to meet and/or maintain the Traffic Service standards are to be included in the required Five Year Capital Improvement Program(see Section 6). 3. Adoterfornunce Standards,Maintained Through Cavital Project&for the Following Item Based on Local Criteria: a. fire c. parks e. water b. police d. sanitary facilities f. flood control Jurisdictions may have already adopted performance standards for some.or all of these items. Performance standards shall be adopted for inclusion in each local jurisdiction's General Plan. Each jurisdiction shall comply with the adopted standards. The Performance Standards should take into account fiscal constraints,and how the standards are to be applied in each jurisdiction's development review process. To ensure the continued applicability of these standards,each jurisdiction may annually review and modify their adopted standards,in consultation with special districts where appropriate,and provide an opportunity for public comment. Capital projects,exclusive of operating budgets,to achieve and/or maintain Performance Standards are to be included in the required Five Year Capital Improvement Program(see Section 6). 4. Adopt a Develonment Mitigation Program to Ensure that New Growth is Paying its Share of the Costs Associated .L1_ with that Grow-in Local jurisdictions, for the most part, already impose fees for a variety of purposes including site specific traffic improvements. Only a few jurisdictions impose fees for regional traffic mitigation. To meet the requirements of this Section,each jurisdiction shall-. 1) Ensure that revenue provided from this measure shall not be used to replace private developer funding which has been or will be committed for any project. 2) Adopt a development mitigation program to ensure that development is paying its share of the costs associated with that development. In addition.,the Authority shall: 1) Develop a program of regional traffic mitigation fees,assessments or other mitigations,as appropriate,to fund regional and subregional transportation projects,as determined in the Comprehensive Transportation Plan of the Authority. 2) Consider such issues as jobs/housing balance,carpool and vanpool programs and proximity to transit service in the establishment of the regional traffic mitigation program. 3) The development mitigation program will be implemented with the participation and concurrence of local jurisdictions in determining the most feasible methods of mitigating regional traffic impacts. Existing regional traffic impact fees shall be taken into account by the Authority. 1-13 1.Introduction AIM* 5. Partici ate in a CooDerative.Multi-Jurisdictional Plannini!Process to Reduce Cumulative Reeional Traffic ImDacts of Develooment AVWA" The Authority shall establish a forum for jurisdictions to cooperate in easing cumulative traffic impacts. This will be accomplished through the Regional Transportation Planning Committees,and be supported by an ongoing countywide comprehensive transportation planning process in which all jurisdictions shall participate. As part of this process,a uniform database on traffic impacts will be created,based on the countywide transportation computer model. Use of the countywide transportation computer model provides an opportunity to test General Plan(s)transportation and land use alternatives,and to assist cities and the county in determining the impact of major development projects proposed for General Plan Amendments. This would provide a quantitative basis for inter-jurisdictional negotiation to mitigate cumulative regional traffic impacts. Input for the model shall include each jurisdiction's Five Year Capital Improvement Program of transportation projects(see Section 6)and the projects of federal,state and regional agencies such as Caltrans,transit operators,the Metropolitan Transportation Commission,etc. In addition,the computer model database will include each local jurisdiction's anticipated land use development projects expected to be constructed within the next five years. 6. DeveloD a Five Year Capital Imvrovement Program to Meet and/or Maintain Traffic Service and Performance Standards(ID ned in Sections 2 and 3) Each jurisdiction shall determine the capital projects needed to meet and/or maintain both its adopted Traffic Service and Performance Standards. Capital financial programming will be based on development to be constructed during(at a minimum)the following five year period. The Capital Improvement Program shall include approved projects and an analysis of the costs of the proposed projects as well as a financial plan for providing the improvements. 7. Address Housing Options and Job Opportunities As part of its Five Year Capital Improvement Program and pursuant to the state mandated housing element of its General Plan,each jurisdiction shall develop an implementation program that creates housing opportunities for all income levels. Each jurisdiction shall also address land use information as it relates to transportation demand as well as discussion of each *Now* jurisdiction's efforts to address housing options and job opportunities on a city,subregional and countywide basis. 8. Adopt a Transportation Systems Management(TSM)Ordinance or Alternative Mitigation To promote carpools, vanpools and park and ride lots, the Transportation Authority will draft and adopt a Model "mum Transportation Systems Management Ordinance for use by local jurisdictions in developing local ordinances for adoption and implementation. Upon approval of the Authority,cities with a small employment base may adopt alternative mitigation measures in lieu of adopting a TSM Ordinance. EXPENDITURE PLAN GROWTH MANAGEMENT PROGRAM APPENDIX A-INFORMATION ON LAND USE DEFINITION These definitions are for information,guidance and are subject to local jurisdictions'determination in the application of Traffic Service Standards. Rural Rural areas are defined as generally those parts of the jurisdiction which have been designated in the General Plan for agricultural or open space uses and which are characterized by medium to very large parcel sizes(10 acres to several thousand acres). These areas have very low population densities,usually no more than I person per acre or 500 people per square mile. Semi-Rural Semi-Rural areas are defined as generally those parts of the jurisdiction that are designated in the General Plan for agricultural,open space or very low w density residential uses,with predominant parcel sizes down to as small as 2 to 3 acres. These areas may support viable agricultural operations,but the operations generally occur on small to medium sized lots. These areas are also characterized by clusters of farm housing or very low density"ranchette"development. The population densities in these areas usually range between some 500 to 1,000 persons per square mile(1.0 to 1.5 persons per acre). 1-14 low 1.Introduction Suburban Suburban areas are defined as generally those parts of the jurisdiction that are designated in the General Plan for low and medium density single family homes; low density multiple family residences; low density neighborhood and community oriented commercial/industrial uses;and other accompanying uses. Individual structures in suburban areas are generally less than 3 three stories in height and residential lots vary from about 6,000 square feet up to 2 or 3 acres. Population densities in suburban areas fall within a wide range,from about 1,000 to 7,500 persons per square mile(1.5 to 12.0 people per acre). Urban Urban areas are defined as generally those parts of the jurisdiction that are designated in the General Plan primarily for multiple family housing, with smaller areas designated for high density single family homes;low to moderate density commercial/industrial uses;and many other accompanying uses. Urban areas usually include clusters of residential buildings(apartments and condominiums)up to fl=or four stories in height and single family homes on relatively small lots. Many commercial strips along major arterial roads are considered urban areas. Examples of urban areas.in Contra Costa County are the older neighborhoods in Richmond,El Cerrito,Pittsburg,and Antioch and the downtown commercial districts in smaller cities such as Martinez,Danville,and Lafayette. Population densities in urban areas are usually at least 7,500 persons per square mile(12.0 people per acre). Employment densities in commercial areas may range up to about 15 jobs per acre. Central Business District/Maior Commercial Center Central business districts or major commercial centers are defined as those areas designated in the General Plan for high density nn ial and residential uses. They consist of either the downtown area of a major city(Concord,Walnut Creek,Richmond,and the Pleasant Hill BART station area)or a large business park(such as Bishop Ranch).These areas are characterized by large concentrations of jobs and consist of clusters of buildings four stories or more in height. CBD`s or major commercial centers generally have high employment densities. Routes of RIgional Signiflcance Routes of regional significance are generally those that serve travel across Contra Costa County(for example,eastern Contra Costa to central Contra Costa),or between Contra Costa County and adjacent counties. Examples of routes of regional significance include:the Interstate and State Highway system,Ygnacio Valley Road,Treat Boulevard,San Pablo Avenue,San Pablo Dam Road,Lone Tree Way,etc. CONTRA COSTA TRANSPORTATION IMPROVEMENT AND GROWTH MANAGEMENT ORDINANCE#88-01 The Contra Costa Transportation Authority ordains as follows: SECTION 1-- TITLE This Ordinance shall be known and may be cited as the Contra Costa Transportation Improvement and Growth Management Ordinance(#88-01)which shall establish and implement a retail transaction and use tax. SECTION 2—EXPENDITURE PLAN PURPOSES This Ordinance provides for the implementation of the Contra Costa Transportation Improvement and Growth Management Expenditure Plan, as approved and adopted by the Contra Costa Transportation Authority, which will result in countywide transportation facility and service improvements including highway improvements, public transit improvements, trail facility improvements,local street maintenance and improvements and related transportation programs. These needed improvements shall be funded by the retail transactions and use tax provided for in Section 3 of this Ordinance. The revenues shall be deposited in a special fund and used solely for transportation projects and programs.

Section 2 Summary Through this ordinance the people approve the policies contained in the 65/35 Contra Costa County Land Preservation Plan and direct the Contra Costa County Board of Supervisors to reflect those policies in the new general plan(the"New General Plan")for the County. These"65/35 Land Preservation Plan"policies are intended to: .-NOW 0 Restrict urban development to 35%of the land in the County and preserve 65%of the land in the County for agriculture, open space,wetlands,parks and other non-urban uses; 0 Prohibit any changes to the 65/35 Land Preservation Plan standard except by a vote of the people; 0 Create an Urban Limit Line to identify the outer boundaries of urban development in the County; 0 Protect and promote the economic viability of agricultural land by appropriate standards and policies,including a policy that increases the minimum parcel size for prime productive agricultural land outside the Urban Limit Line to 40 acres; 0 Protect open hillsides and significant ridgelines throughout the County from development by zoning and other measures; 0 Manage growth in the County by allowing new development only when infrastructure and service standards are met; 1-24 1.Introduction 0 Advise the Local Agency Formation Commission to honor the County's 65/35 Land Preservation standard,Urban Limit Line and growth management standards in annexation and incorporation decisions; 0 Promote cooperation between the County and cities to preserve agricultural and open space land,wetlands and parks,by requiring the County to pursue preservation agreements with cities where feasible;and 0 Safeguard the County's obligation to provide its fair share of safe,decent and affordable housing. Section 3 Statement of Findings and Policy The voters of Contra Costa County approve the 65/35 Land Preservation Plan based on the following facts and considerations: A. Contra Costa County(the"County")is nearing completion of a major revision of its general plan. The New General Plan will represent a comprehensive,balanced approach for accommodating the diverse variety of needs and interests of the people of the County. To maximize public participation in preparing the New General Plan,the County has held thousands of hours of public meetings and received extensive written comments on the New General Plan. All segments of Contra Costa County society have participated,including ranchers,developers,farmers,environmentalists,labor groups,cities, special districts,business and industrial associations. The proposed New General Plan expresses the variety of concerns and hopes stated in this public process. The proposed New General Plan consists of over 400 pages and represents years of research and analysis by the staffof the County Community Development Department and outside consultants. In addition, in accordance with the California Environmental Quality Act("CEQA"),the County has prepared and circulated for public review a draft environmental impact report("EIR")to assess the environmental impacts ofthe New General Plan. The draft EIR,,comments and responses to comments have been circulated to agencies and individuals and readily available at County offices,libraries and other public places. B. During this process of preparing the New General Plan, the voters expressed a number of concerns related to future planning and development of the County. The most important of those concerns were: (1) Growing urbanization of the County is threatening the long term viability of the County agricultural and open space land,parks,wetlands,hillsides and ridgelines. Preservation and buffering of agricultural land is critical to maintaining a healthy and competitive agricultural economy and assuring a balance in land uses in the County. Moreover,preservation and conservation of open space,wetlands,parks,hillsides and ridgelines is imperative to ensure the continued availability of unique habitats for wildlife and plants,to protect the unique scenery in the County and to provide a wide range of recreational opportunities for County residents. (2) Growth is a natural and proper part of the life of the community. However, growth should be managed responsibly to preserve the quality of life for current and future generations. New development should be guided into appropriate locations,and should be allowed only after appropriate infrastructure(transportation,schools, water,fire and police protection)can be assured. (3) There is a critical need to make decent, safe and affordable housing available to all Contra Costa County residents. Fair housing opportunities should prevail for all economic segments of the County,and housing should be available in reasonable proximity to employment centers. In addition,the County's land use policies should not restrict growth so severely that they preclude these affordable housing opportunities. C. The 65/35 Land Preservation Plan implemented in Section 4 is intended to address these concerns ofthe voters. The 65/35 Land Preservation Plan is intended to carry out the voters'desire to both preserve agriculture and open space land,parks, wetlands,hillsides and ridgelines,manage growth to protect the quality of life,and provide for the County's fair share of decent,safe and affordable housing. D. it is appropriate and reasonable to present to the voters for their approval the key policies that would guide the County's future under the New General Plan,as those policies are set forth in the 65/35 Land Preservation Plan. With the guidance and confirmation the voters can provide through approval of the 65/35 Land Preservation Plan,the County can complete the environmental review and detailed documentation necessary for implementing these principles. E. The approval of the 65/35 Land Preservation Plan by the voters is not intended to be an amendment of the County's existing general plan. Rather,the 65/35 Land Preservation Plan,if approved by the voters,is intended to be reflected in the County's New General Plan and will thereby become the official policy ofthe County with respect to the preservation of open space and agricultural lands and the protection of valuable environmental resources such as wildlife,wetlands,hillsides and ridgelines. Section 4 Imolementation of 65/35 Land Preservation Plan To implement the 65/35 Land Preservation Plan,the following chapter is hereby added to the Contra Costa County Ordinance Code as Chapter 82-1 and numbered appropriately: 1-25 1.Introduction Now"$ A. New General Plan OOMO. The County shall adopt a new general plan by December 31, 1990(the"New General Plan"). B. 65/35 Land Preservation Plan *soft The policies contained in this chapter shall be reflected in the New General Plan,as ultimately adopted by the Board of Supervisors in accordance with the California Environmental Quality Act and State Planning Law. (1) 65/35 Land Preservation Standard smwft- Urban development in the County shall be limited to no more than 35%of the land in the County. At least 65% of all land in the County shall be preserved for agriculture,open space,wetlands,parks and other non-urban uses. (2) Changes to the 65/35 Land Preservation Plan No change shall be made in the New General Plan after its adoption that would result in greater than 35%of the land in the County being permitted for urban development. This limitation shall not prevent any increase in agriculture,open space,parks,wetlands or other nonurban uses to greater than 65%of the land in the County. (3) Urban Limit Line To ensure the enforcement of the 65/35 standard set forth in(B)(I)above,an Urban Limit Line shall be established,in approximately the location depicted on the illustrative 65/35 Contra Costa County Land Preservation Plan Map attached as Exhibit A.The Urban Limit Line shall be incorporated into the Countys Open Space Conservation Plan.The Urban Limit Line shall limit potential urban development in the County to 35%ofthe land in the County and shall prohibit the County from designating any land located outside the Urban Limit Line for an urban bM use.The criteria and factors for determining whether land should be considered for location outside the Urban Limit Line should include(a)land which qualifies for rating as Class I and Class 11 in the soil Conservation Service Land use Capability Classification,(b)open space,parks and other recreation areas,(c)lands with slopes in excess of26 percent(d)wetlands,and(e)other areas not appropriate for urban growth because of physical unsuitability for development unstable geological conditions, inadequate water availability,the lack of appropriate infrastructure,distance from existing development,likelihood of substantial environmental damage or substantial injury to fish or wildlife or their habitat,and other similar factors. (4) Growth Management In accordance with the Contra Costa Transportation Improvement and Growth Management Program adopted on NORM August 3, 1988,the County shall manage growth by allowing new development only when infrastructure and service standards are met for traffic levels of service,water,sanitary sewer,fire protection,public protection, parks and recreation,flood control and drainage and other such services. Land located inside the Urban Limit Line may be considered for changes in designated land uses,subject to County growth management policies and any other applicable requirements. Location of land within the Urban Limit Line shall provide no guarantee that the land may be developed. If land is developed within the Urban Limit Line,a substantial portion of this land shall be retained for open space,parks and recreational uses. (5) Agricultural Protection Policies-,Minimum Parcel Sizes The County shall establish standards and policies designed to protect the economic viability ofagricultural land These suxU& and policies shall include ami tirnaumparcel size for productive agricultural bW located outside the Urban Lm*I=to 40 acres.These standards and policiesmayalso include,but shall not be&T&dtc, 1' -1diVemimsts mfisavafion M6N ?"IM111=1 clustering establishn=t ofan agricultural soils hug fund,and agricultural mitigation fees. (6) Hillside Protection Development on open hillsides and significant ridgelines throughout the County shall be restricted,and hillsides with a grade of 26%or greater,shall be protected through implementing zoning measures and other appropriate actions. 1-26 1.Introduction (7) Chan es to the Urban Lindt Line There shall be no change to the Urban Limit Line that violates the 65/35 standard set forth in B(l)above. After adoption of the New General Plan,as long as there is no violation of the 65/35 standard,the Urban Limit Line can be changed by a 4/5 vote of the Board of Supervisors after holding a public hearing and making one or more of the following findings based on substantial evidence in the record: (a) a natural or man-made disaster or public emergency has occurred which warrants the provision of housing and/or other community needs within land located outside the Urban Limit Line; (b) an objective study has determined that the Urban Limit Line is preventing the County from providing its fair share of affordable housing,or regional housing,as required by state law,and the Board of Supervisors finds that a change to the Urban Limit Line is necessary and the only feasible means to enable the County to meet these requirements of state law, (C) a majority of the cities that are party to a preservation agreement and the County have approved a change to the Urban Limit Line affecting all or any portion of the land covered by the preservation agreement; (d) a minor change to the Urban Limit Line will more accurately reflect topographical characteristics or legal boundaries; (e) a five(5)year periodic review of the Urban Limit Line has determined,based on the criteria and factors for establishing the Urban Limit Line set forth in B(3)above,that new information is available(from City or County growth management studies or otherwise)or circumstances have occurred,that warrant a change to the Urban Limit Line; M an objective study has determined that a change to the Urban Limit Line is necessary or desirable to further the economic viability of the East Contra Costa County Airport,and either(1)mitigate adverse aviation related environmental or community impacts attributable to Buchanan Field,or(ii)further the County's aviation related needs;or (9) a change is required to conform to applicable California or federal law. Any such change shall be subject to referendum as provided by law. Changes to the Urban Limit Line under any other circumstances shall require a vote of the people. (8) Annexations and Incorporations The Local Agency Formation Commission('IAFCU)shall be advised to(a)respect and support the Cuutys 65/35 Preservation Standard,Urban Limit Line and growth---- --mG!111[slandardsWheri w—isi&ingrequests fori action %ationtocities __ - AR orservice distriM(b)apply the stricter of the growth nmnam�____ standards of either the County theiu 14Lu18city or the annexing city or service district,when considering mquests for i orant xafimoflaridtocidesorsovicedistdcts,and (C)require unincorporated land located within the Urban Limit I"ft is included in the ofanewcityorarinmed to a city to provide a fair share of affordable housing when and if such land is developed. (9) Housine As required by the State Planning Act,the County shall periodically review and update the New General Plan to conform to state housing requirements and to ensure its capacity to accommodate a variety of housing types and prices throughout the County. In accordance with the provisions of B(7)above,the Board of Supervisors may make findings of necessity that the Urban Limit Line should be changed to allow the County to meet its fair share of affordable housing and other state housing requirements. (10) Cooperation with Cities To the extent feasible,the County shall enter into preservation agreements-with cities in the County designed to preserve certain land in the County for agriculture and open space,wetlands or parks. C. Application to Protects Prior to Adoption of New General Plan From the effective date of this chapter to adoption of the New General Plan,prior to issuing a perrnit for any project or adopting any legislation which requires an initial study under the California Environmental Quality Act,and prior to issuing a permit for any 1-27 ..-Mft 1.Introduction wmum demolition,conversion,or change or use,and prior to taking any action which requires a finding ofconsistencywith the general plan,the County shall adopt findings as to whether or not the proposed project or legislation is consistent with the policies established above.

PLANNING FRAMEWORK 2.1 INTRODUCTION This chapter provides some background information on Contra Costa County and sets the stage for the following General Plan goals, policies, and implementation measures. The chapter describes the physical setting of the County and its place in the bay region; the political setting of the incorporated and unincorporated areas;the social and economic setting of the County residents. The chapter also summarizes as background,recent trends from 1980 to 7003 regarding population and housing growth within each of the 4-8-20 general purpose jurisdictions in the County. 2.2 PHYSICAL SETTING Contra Costa County is adjacent to Alameda, San Joaquin, Sacramento and Solano counties in Northem California. The County stretches approximately 40 miles from west to east and approximately 20 miles from north to south. The County covers a total of 805 square miles,of which approximately 732 square miles(468,500 acres)are land,with the remainder consisting of water areas. In terms of how understanding this physical setting relates to the planning framework,it is important to keep in mind that the County has nominal control,if any,over growth and planning in adjacent counties and cities within the County. Nevertheless,growth and planning in these communities will impact the County and the realization of planning assumptions in this General Plan. Contra Costa County contains a very diverse social and physical environment,although it is often perceived to consist of a series of affluent suburbs. While portions of western and central Contra Costa resemble many urban and suburban environments, the far eastern comer of the County more closely resembles the predominantly agricultural communities of the San Joaquin Valley. GENERAL PURPOSE JURISDICTIONS This Plan uses the conunon distinction made by residents to differentiate between the various geographic sub-areas of the County. Six different sub-areas of Contra Costa are illustrated in Figure 2-1. The County is usually considered as comprising three distinct areas: West County,Central County,and East County. Central County is finther generally considered as comprising North Central County,Lamorinda,and the San Ramon Valley. East County is composed of the Pittsburg-Antioch area and"Other East County." Each of these areas is described below. West County The West County area includes the urbanized shoreline of the San Francisco and San Pablo Bays,which is separated from the rest of the County by the Briones Hills and the open space watershed lands owned by the East Bay Municipal Utility District. West County was among the fast areas of the County to develop with medium density suburbs and industry. The western sub-area includes the cities of El Cerrito,Richmond, San Pablo,Pinole,and Hercules,as well as the unincorporated communities of Kensington,El Sobrante,Rodeo,Crockett,and Port Costa. 2-1 :Y M M .i r �•, I ` 1 ♦ i I IIf rri - I ----- +n i � U �• , � fir i� � �u�a� iul kn con � .Q �► C � V wr � orl Q lot ` t ..1 tam .iZ M o wFA o U �r ..... /010 cc3 I r cr c _ • tC r j fun Qui 'r o r i ♦ �. ug �' e4 td ,,w" ;-4 43 Q spy Page 2-2 2.Planning Framework Central County The Central County area is the largest of the three areas,including ten of the%eitAR14-101 nineteen cities in Contra Costa and over half of the total population. Central County is composed of mostly low density bedroom communities that have developed in the flat valleys between the East Bay Hills and the Diablo Range to the east,extending north and south of Mt.Diablo. The cities within this area are as follows: 0 Lamorinda: Lafayette,Moraga and Orinda,as well as the unincorporated area of Canyon; 0 North Central County: all of the cities and unincorporated communities along the northern Interstate 680 corridor—the cities of Walnut Creek, Concord, Clayton, Pleasant Hill, and Martinez and the unincorporated areas of Pacheco,Vine Hill,Clyde,the Pleasant Hill BART station,and Saranap; 0 San Ramon Valley: unincorporated Alamo, the cities of Danville and San Ramon, and the unincorporated Blackhawk and Tassajara area. East County East County is the largest land area in the County and includes much of the hilly terrain of the Diablo Range: 0 Pittsburg-Antioch area, which stretches along Route 4 from the Willow Pass grade northeast of Concord to Route 84 near Oakley. The Pittsburg-Antioch area includes the two cities,as well as the unincorporated community of Bay Point. 0 "Other East County"refers to the remainder of the East County sub-area,which includes the cities of Brentwood,and Oakley and the unincorporated areas of O.-MIrclie, 164.RW Bethel Island,Knightsen,Byron,and Discovery Bay. 2.3 POLITICAL SETTING This section first discusses as background, the political history of the unincorporated areas, and their involvement with the cities. Then the relationship between the County General Plan and the cities within the County is described. Finally,the section discusses the major local,regional and State governmental agencies and groups that make or affect planning decisions for the unincorporated areas. POLITICAL HISTORY OF UNINCORPORATED AREAS The unincorporated area includes a variety of urban pockets within every County area. A number of physical and political factors have caused these geographic areas to remain unincorporated. Urban Areas Historically, many property owners have preferred that their area remain under the County's jurisdiction (unincorporated)rather than be incorporated into a city because,before the passage of Proposition 13 in 1978, property taxes were appreciably lower. Additionally, many property owners preferred the less developed character of these areas. Cities chose not to annex particular unincorporated pockets for a number of other reasons. Sanitary sewers,curbs, gutters,sidewalks, street lights and other standard improvements were not required by the County at the time many of the unincorporated pockets were developed. As a result,cities were hesitant to annex unincorporated pockets where major capital expenditures were required to bring them up to city standards. Today,these factors continue to discourage the annexation of already urbanized unincorporated pockets by adjacent cities. 2-3 2.Planning Framework Rural Areas MUNN. Within Contra Costa County,the vast majority of unincorporated lands are located in rural(or non-urban)areas. These areas remain undeveloped or developed at very low densities. In the past,public policy has discouraged the mom annexation of the rural unincorporated areas to cities because most rural lands are located far from the boundaries of cities,often making the provision of urban services from cities physically ulyladfical and economically unfeasible. It is for these reasons,as well as to discourage urban sprawl,that the Local Agency Formation Commission(LAFCO) 800aft has not assigned city spheres of influence for most unincorporated rural lands. This General Plan provides a framework for the interplay between growth management,the Urban Limit Line and the 65/35 Land Preservation Standard as General Plan policies affecting,among other things,growth in and the preservation of rural areas. ONNOW RELATIONSHIP BETWEEN THE COUNTY GENERAL PLAN AND THE CITIES Planning is a required function of local government in California. The Board of Supervisors and the Planning Commissions, with the assistance of the Community Development Department,are responsible for planning for unincorporated areas. Likewise,each of the County'stai.alfikeewnineteep incorporated cities plans for lands within its swam own jurisdiction. Preparation of the General Plan required an understanding of the General Plans of these 4S-19 cities and development and growth contemplated in those general plans. To develop that understanding,the County J . .1%.#W&W J"~,Ka%a the city General Plans-4a(46 E)%no tia lfinft-o m&Lt e att i t6la ea%44 8 ul famogy Of staff collected ffin%45 SAAW-F I kta�'Llona-* C-itu awi Cgmulu C'S&MADVAI Din. Among other things,this do-W.1,44 A.fflt effort noted differences between County and City Plans for city Spheres of Influence as well as differences in County and city schemes for classifying land uses. To construct a uniform Countywide land use data base,the City General Plans were translated into uniform CounLy land use designations. The vacant lands within cities and the County were then"built out"to enable the County to develop estimates of population,jobs and housing in the County of land for parks or Public facilities these actions were reflected using Count y land use categofies. Spheres of Influence and LAFCO A Sphere of Influence(SOI)boundary is adopted for each city and special district by the Local Agency Formation Commission (LAFCO) of Contra Costa County. The Sphere line includes lands outside the jurisdictional boundaries of the city or district which are expected to be ultimately annexed and served by the agency. Local Apencv Formation Commission AFC The Local Agency Formation Commission was created by the Legislature in 1963 and is responsible for the discouragement of urban sprawl and the encouragement of the orderly formation and development of local governmental agencies. There is a LAFCO in each county in California except the City and County of San Francisco. LAFCO is a seven-member commission comprised of two city council members,two supervisor members,two special district members and one public member. The tflA41Rae.flets. Cortese-Knox-.Hertzberg,Government Reauthorization Act of 2000 empowers LAFCO to PIN a a carry out its mandate. thaLe K,.:M,d,4,:XL 341.is.19,et Aet., thee D-O i6st-Fieft UA%-eK%1wF& Ae4 "anat.1 1,AAW JLVA%4ALJL%W4rL4A Act. This laws requires LAFCO to decide on proposals for: the incorporation of cities,the annexation or detachment of territory from a city,the consolidation of two or more cities,the formation of a special district,and the dissolution,reorganization,consolidation or merger of a special district. In addition,the Commission has the responsibility of determining the sphere of influence,or ultimate service area boundary,of each city and special district in the County. In recent years,there have been a number of sphere of influence studies completed by LAFCO that have explored the ultimate service area boundaries for some of the major unincorporated areas. City-County Development Procedures 2-4 -- 2.Planning Framework Development within a city's Sphere of Influence maybe approved and constructed under County jurisdiction or in the alternative,a developer may request that a project*involving property within the Sphere be approved and annexed into the city. A city must then adopt a General Plan designation for the property(if the city's General Plan does not already indicate a designation for it)and pre-zone the parcel(indicate what the zoning will be when it is annexed). The County LAFCO then votes on the annexation request. Also,there is an increasing effort for the County and cities,in certain circumstances,to conduct joint planning. Figure 2-2 illustrates the relationship between a hypothetical incorporated territory,its Sphere of nfluence and its extended planning area. Figure 2-3 illustrates all of the Sphere of Influence boundaries for the 4-9-1.9 cities and their unincorporated and incorporated limits. Due to the fact that these SOI boundaries often change,the reader should consult with LAFCO or the County to determine the most current SOI information. Trends In City Growth Over the last decade as unincorporated land areas adjacent to cities have been annexed and developed,and the incorporation of new cities has been approved,the County's role in approving and servicing new residential areas has shrunk dramatically. In 1980,approximately 44 percent of all the housing that was built occurred under County jurisdiction,with the remainder(56 percent)approved by the cities. The cities'portion of residential growth climbed to 67 percent of the total in 1982,and reached 77 percent in 1984,following the incorporation of Danville and San Ramon. Since 1984,the portion of growth occurring in the County as compared with the cities has remained steady at a ratio of about three quarters of the new housing developed within the cities and one quarter built in the County. This illustrates that since the County has very little control over the type or extent of development that occurs within city boundaries, to a large extent it cannot control the growth which occurs within cities. City-County Issues Related To Measure C- 1988 Measure C- 1988 added one-half cent to the sales tax within the County for the purpose of funding needed transportation improvements. Approximately 18 percent of the approximately$800 million collected through the 20-year term of the tax can be allocated to cities and the County if they have adopted Growth Management Elements in their local General Plans. The measure sets forth specific intersection traffic service levels keyed to land use type. In general, the lowest levels of service are allowed in the highest density areas (central business district)and highest in the lowest density areas(rural). Projects which would affect traffic service levels at intersections must include mitigation measures for the effects,or they cannot be approved.,Additional standards for sewer water,storm drainage,police,fire,and parks must also be included in local General Plans, although the measure gives these services to the local agency. City-County Issues Related to Measure C-1990 Measure C-1990 established a 65/3 5 Land Preservation Standard which limits urban development to no more than 3 5 percent of the land in the County and preserves at least 65 percent of land in the County for agriculture, open space,wetlands,parks and other non-urban uses. The urban areas within cities(and the urban growth of cities in the County)is factored into this 35 percent ceiling for urban growth in the County. (See Land Use, Open Space Elements.) Measure C-1990(and therefore this General Plan)also provides that the County shall,to the maximum extent feasible,enter into preservation agreements with cities in the County designed to preserve land for agriculture, open space,wetlands and parks. This General Plan, in accordance with Measure C - 1990, also provides for County- City cooperation on growth policies through the annexation and incorporation process. (See Section 3,Land Use Element.) 2-5 2.Planning Framework ROLE OF THE BOARD OF SUPERVISORS,PLANNING COMMLSSIONS9 COUNTyADMINIM[RATOX AND CONEVIUNITY DEVELOPMENT DEPARTMENT Board of Supervisors W."A The Board of Supervisors,a five-member body,has direct jurisdiction for land use in unincorporated areas. As the County's legislative body,it is the Board of Supervisors that ultimately adopts the General Plan and acts on zoning and subdivision matters for unincorporated areas. County Planning Commission OMMO The Planning Commission advises and makes recommendations to the Board of Supervisors on the General Plan, zoning,and subdivision proposals. Certain other decisions made by the Commission are subject to appeal by the Board -- of Supervisors. The Planning Commission consists of seven members,each appointed by the Board of Supervisors. Area Planninia Commission The County Board of Supervisors has established two area Planning Commissions: the East County Regional Planning Commission(sexvien ve members)and the San Ramon Valley Area Regional Planning Commission (seven members). While the County Planning Commission reviews and recommends on matters of County- wide concern,the area planning commissions review entitlements within their respective jurisdictions. Zonin,a Administrator The Zoning Administrator holds public hearings on variance permits,development plans minor subdivisions and some maj or subdivisions. The Zoning Administrator also may review and recommend environmental documentation under CEQA and make recommendations on development agreements. Community Development Department The Community Development Department advises the P Commission,carries out technical work on the General Plan,and pmpans recommendations on cun-ent planning r-na-t—ILINS,such as development applications. In many cases,the Board of Supervisors has delegated the responsibility for day-to-day current planning matters to the staff of the Community Development Department subject to appeal to the Planning C-r-umwsion and the Board of Supervisors. ROLE OF ADVISORY GROUPS Municipal Advisory Committees Municipal Advisory Committees are located in Bay Point,Bethel Island,Byron,Dtablo,Discovery Bay,El Sobrante,Kensington,Knightsen,North Richmond,0'..%ea"KIN ery ',Pacheco,Pleasant Hill BART,and Rodeo. Duties of these groups are specified in the Government Code and by Board direction establishing the MACS. 2-6 won& - -- - -- -- .

Page ♦ 2-8 Weill 2.Planning Framework REGIONAL PLANNING AGENCIES There are a number of agencies that are mandated by State law to prepare areawide plans,with which local general plans should be coordinated. Included in this category are the Association of Bay Area Governments (ABAG)and the Metropolitan Transportation Commission(MTC). Association of Bay Area Governments(ABAG) ABAG was created in January 1961. It was founded in recognition of the fact that the physical,economic and social well-being of the entire region and of its individual communities depends on continuing areawide cooperation and coordination. It provides a forum for addressing regional problems and for formulating and implementing regional development policies. ABAGs prognarm are financed by membership dues,special assessments,grants,other regional agencies,and the State and Federal governments. Its governing board is composed of elected city and county officials. ABAGs regional growth projections serve as the foundation of Federal and State mandated regional plans and review of Federally flinded programs in the region. As the council of govemments for the Bay Area,ABAG is sornefinies required by State law to perform certain functions for the region. For example,ABAG is required to determine existing and projected housing need for the region and for each jurisdiction. In turn,local governments are required to use this information as a basis ofthe housing needs discussion required in the Housing Element An explanation ofthe use ofthe ABAG projections in the County's projections is contained in the Land Use Element. Since 1967, there has been a regional plan for the San Francisco Bay Area. Produced and maintained by ABAG,, the Plan seeks to guide the economic, social, and environmental future of the nine-county region. Specifically,the Plan provides regional goals,objectives and policies on the following topics: (1)housing,(2) economic development,(3)environmental quality,(4)safety,(5)recreation,(6)transportation,and(7)health. In addition to regional policies, the Plan also presents policies for subregions. These subregional policies determine what short-range actions are necessary to implement long-range regional policies. The Regional Plan of Contra Costa County is divided into three subareas: (1) West County, (2) Central County,and(3)East County. There are no policies for the first subarea,while for the Central and East County there are very specific policies that ABAG and the Metropolitan Transportation Commission(N4TC)will apply when evaluating important public service improvements(e.g.,water,wastewater,and transportation)which need federal funding. These policies were originally developed as part of a planning study conducted by ABAG and MTC in 1984, and basically seek to coordinate the provision of public facilities with land use decisions in order to concentrate development in urban areas and to preserve natural and scenic resources. Metropolitan Transportation Commission(MTC) MTC! carries out comprehensive transportation planning for the nine-county, San Francisco Bay Area. MTC is required to prepare a Regional Transportation Plan and Transportation Improvement Program covering highways, selected mass transit, railroads and aviation facilities and services. All street, highway, and most mass transit projects supported by Federal and State transportation grants must be consistent with these plans and program. STATE AGENCIES THAT EXERCISE DIRECT LAND USE CONTROL IN CONTRA COSTA COUNTY State agencies having direct control over land use in Contra Costa County include, without limitation, the Department of Parks and Recreation,which maintains parks on Cowell Ranch ,Mt. Diablo Pafk and Franks Tract;the Department of Fish and Game,which regulates stream bank alteration;and Caltrans,which regulates freeway right of ways;aftd-the Bay Area Air Quality Management District which regulates air quality;and the Res Tonal Water Oualitv Control.Beard which regulates'%vater quality-issues. FEDERAL AGENCIES THAT EXERCISE LAND USE CONTROL IN CONTRA COSTA COUNTY 2-9 2.Planning Framework Federal agencies having regulatory authority affecting land use and growth issues in Contra Costa County am=" include,without limitation,the Environmental Protection Agency,the Army Corps of Engineers,and the Fish and Wildlife Service. 2.4 SOCIAL AND ECONOMIC SETTING POPULATION Contrary to some common misconceptions,Contra Costa County was not one ofthe fastest growing areas in California during the 1980's. During the period 1980 through 1990,California grew by almost 6.1 million residents or by 20.5 percent More than half(59 percent)of this population growth,or about 3.7 million new residents,occurred in the five counties of Los Angeles,San Diego,Orange,San Bernardino,and Riverside in Southern California. .POEM Only 13.8 percent of the State's population growth during the same period was in the San Francisco Bay region,which grew by about 840,000 persons between 1980 and 1990. In 1990 the Bay Area was home to 6 million residents scattered throughout nine counties. Four of the counties in the Bay region grew very slowly during the 1980's(Marin,3.4%,Napa, 11.7%San Mateo, 10.6%and San Francisco,6.6%). The two largest counties (Santa Clara, 15.6% and Alameda, 15.7%) grew at a steady rate that was less than the statewide average,while the remaining two northern counties(Solano,44.6%,and Sonoma,29.5)experienced higher growth rates,as they changed from a rural to suburban environment.. Contra Costq's,g.rmyth rate was 212.4%. Although Contra Costa's growth rate during the 1980 to 1990 period (22.4 percent) was higher than the regional average,it is interesting to note that in the East Bay,Alameda County added 15 percent more residents (173,803) in the decade than Contra Costa 147,352), The 1990 Contra Costa County population was at 803,732 as recorded in the U.S. Census. Table 2-1 shows the 1980 and 1990 demographic settings. Between 1990 and I Q0 401 000 the liation-of Contra Costa tla 9FOWPODulation increased from 803,732 to 8..8.23.3.90948.81.6,an increase of 4.418-1 Dercent(Table 2- IA). a 5 4QA4 144,20 000 unitc.iqr Ly 4 4-mal-Aef houtrh C Costa's rate du 90 to 2000 an"Oft -W W j%.r'-'%j %4'jL2­&j.%�j%"& 16.F.7 %$'* # VW 'W �A-.-Ajt Contra Cos sgrovvih niia 19 period 18.1%') -vas higlier than the regional average12.7% it is interesting to note that in the East Bay. Alameda County added_15_ ercent more residents 167.039 in the decade than did Contra Costa(145.084) and Santa Clara Count 's imulation increased by 185,008,persons or 27.5% more than Contra Costa's population. Table 24 shows the 1980, 1,990 and 2000 demoLyraDbic changes in Contra Costa County. The increase for the nine Bay Area Counties was 7.65 percent from 1990 to 1995. San Francisco had the lowest growth rate,4.9 percent, and Sonoma and Solano Were the highest with 11.3 and 10.9 percent,respectively. The smallest numbers of growth occurred in Napa County(10,000)and the largest in Santa Clara(110,123).

According to ABAGs Projection 2002 the job/housing ratio will remain fairly stable throughout the County. In the.fastest-growling areas of East County,the large amount of new housing planned and approved-means that employment gi•owrth is anticipated to lag far behind. Fol-every new job created in the East County area,two new workers are expected to more in.and the lopsided jobs/housing ratio in t1le East County coinnlunities will continue throu.gli the early ears of this century. The projected jobs../bousing ratio in eastern Contra Costa County should be improved, however, during the decades beyond the 15-year.planning period of this General Plan. Based upon the market-driven construction trends in other parts of the County and region, the pattens of development in rural areas begins with the construction of suburban housiniz. As the influx of new residents creates the demand for-new services.retail and other'businesses follow the growing population base, although there can be a lag offive years or more between the construction of new housing and the creation of local jobs. This phenomenon occurred in the San .Raman Valley: the eriod ofra id suburbanization during the 1970s and the early 1980s.has been followed by the location of numerous local and regional businesses in the valley du.rin T the 1980s.

As noted preVious:ly, this iobs bousingy anal1fsls assumes that some of the job-generating land uses in the County and Cities' General Plans(the vacant land that-is planned for commercial and industrial growth)will not be developed during the next 1.S Years,because there is too-much of this type of land (especially in East County)set aside for the market to absorb duringthat•hat pet iod6arzi Caumtu . e qAj Ir V vr 11 jAqQ'-QW%.9.14V as faefFew . jobf-sy aFe efW%*%'%W%A6% TV ALL L.FW.01WW.LL&W1 . • K.A. i 7 1 .

Section 65302(a)of the California Government Code reads: "A Land Use Element shafl-that_designates the proposed general distribution and general location and extent of the uses of the land for housing,business,industry,open space,including agriculture,natural resources,recreation,and enjoyment of scenic beauty,education,public buildings and grounds,solid and liquid waste disposal facilities,and other categories of public and private uses of land." The State Code further stipulates that Land Use Element shall include a: "WsStaternent of the standards of population density and building intensity recommended for the various districts and other territory covered by the Plan. The land use element shall ate-identify areas covered by the plan which are subject to flooding and shall be reviewed annually with respect to such areas. As with other elements of the General Plan,the goals,directive policies,and implementation measures of the Land Use Element are mandatory,rather than advisory. Under State law,many land use approvals made by planning commissions and boards of supervisors,including rezoning,subdivisions,development agreements,redevelopment and specific plans, park dedications,and others,must be consistent with and conform to the jurisdiction's General Plan. This General Plan supersedes the County's prior 199-5 - 1010 General Plan(and each of the previously adopted elements such as the 1963 Land Use and Circulation Plan),including area general plans.The policies and maps of many prior general plan amendments and area plans have been reflected in this General Plan. The Land Use Element retains consistency with, and reflects the general plan level of goals,policies and implementation measures as prior adopted Specific Plans. 3.2 RELATIONSHIP TO OTHER GENERAL PLAN ELEMENTS Although the Land Use Element and its accompanying map are often thought by many to be the rmst important part of the General Plan, State legislation requires that the various elements comprise an integrated,internally consistent,and compatible statement of goals,policies,and proms. This means that each of the General Plan Elements are equal in legal status and that the direction given by one element may not be superior or subordinate to that of any other element. Many of the issues that are discussed in the Laird Use Element overlap issues that may be addressed in other General Plan Elemen#s. Almost any issue dealing with the physical c 'cs of land in the County will have land use implications,even if Specific issues such as flooding or prime soils are not extensively in the Land Use Elerr�ent. Readers of this General Plan should dierefore be aware that the policies which may affect development of a specific property are not necessarily stated in only one portion of the Wraps and text in each element. The applicability of policies described in other elerrrents should be taken into consideration when determining the General Plan policies for a particular area or property Readers are referred to the section in Chapter 1, Introduction, entitled "How to Use the General Plan" for a recommended process by which to begin determillifirl the applicability of General Plan maps and policies to specific properties. The Land Use Element contains the following components, suggested by the Governor's Office of Planning and Research(OPR)or required by statute: o inventory and distribution of existing land uses,including nesid+ ,co industrial,open space and agricultural; o general assessment of housing needs based on projected community growth trends; o projections for land use and space for residential, commercial, and industrial development, based upon projections of future population and economic conditions; o population density standards for each land use category with residential potential; o land use goals and policies:County and Area Specific;and o programs for implementation of the land use policies. 3-1 3.Land Use Element Description and analysis of additional land use components are located in the following General Plan Elements: o housing analysis-a detailed discussion is contained in Chapter 6,Housing Element; o educational facilities: assessment of the need for and diagram of existing and proposed future school sites is -- located in Chapter 7,Public Facilities/Service Element; o public buildings and grounds: assessment of existing sites and the location of approved and pending landfill applications is in Chapter 7,Public Facilities/Service Element; WAMP o infrastructure,water and sewer locations and projections,goals,policies and implementation measures are discussed in Chapter 7, Public Facilities/Service Element;in addition to the Growth Managenxmt Elements in Chapter 4; o natural resources: land uses associated with agriculture,vegetation and wildlife,fisheries,mhxml and ale energy,oil and wmn. gas,water(bay,delta,creek),and flood zones;discussed in Chapter 8,Conservation Element; o open space,Urban Limit Line,65/35 Land Preservation Standard: analysis of existing and proposed open space land use is discussed and mapped in Chapter 9,Open Space Elm mclu�ding recreational,scenic,and historic/cultural resources;and o additional implementation programs relating to land use policies and infrastructure standards are located in Chapter 4,Growth Management Element. The Elements are internally consistent and wdize the s,-cune popnl"ar,101,1,11 411JU ke 1.11F -they support policies stated in the other elements, the land use plan maps and the accompanying text to represent a consciously selected balance among the various goals and objectives included in all of the Elements. The balance between governing growth and preserving non-urban areas, for example, must reflect the key interplay in this General Plan between the 65/35 Land Preservation Standard, the Urban Limit Line, the Housing Element goals,and the Growth Management Element infrastructure requirements. Additionally,the Land Use Element's relationship to the other elements of the General Plan provide that: o the land uses are based on the County's best currently available information concerning land use patterns; o actual land use and development decisions may depend upon information not currently available;and o the timing of development of the identified land uses will depend on satisfying the requirements of the Growth Management Element. 3.3 RELATIONSHIP TO SPECIFIC PLANS SPECIFIC PLANS A specific plan is a more detailed plan for a specific area within the County. Specific plans address the planning needs of a particular area,including necessary infrastructure and facilities,land uses and open space. Specific plans,while not a part of this General Plan,must be consistent with all aspects of the General Plan. 3.4 ORGANIZATION OF ELEMENT The Land Use Element is organized in six parts. First, existing land uses are described. A general discussion is given of the various land use characteristics that exist in the West, Central and East sectors of the County. Second, the projected levels of growth used in the General Plan for land uses in the sectors are described. Also discussed are the Cotes Urban Limit Line(ULL) and the 65/35 Land Preservation Standard in relation to the Land Use Element (Furdfer discussion is also provided in Section 4.0,Growth Management Element and in Section 9.0,Open Space Element) The final three sections of this Land Use Element a,n 1 imerate the goals,policies and implementation plans of the County. These policies,which apply only to unincorporated areas,are implemented through other general plan and area plan policies;land use controls,such as the zoning and subdivision ordinances;the requirements within the public service and facility standards;and use of the ULL. 3.5 EXISTING LAND USE For a summary description of the analytical basis of the existing land uses, see Chapter 3.6, Planned Levels of Development.. The General Plan generally recognizes the land use policies of the cities'plans within the city limits with some slight modifications to fit existing land use densities into consistent plan categories. GENERAL INVENTORY OF LAND USES BY SUBAREA Ranging from urban to nual,land is used in Contra Costa County for many purposes. In the West and Central County areas,primary uses of suburban cities and towns are res; t,commercial and industrial. In the East Central County and East County Area,land 3-2 "" 3.Land Use Element is used for agriculture and general open space. References to land within the County or to percentages of the County refer to all of the acreage within the boundaries of the County except the water area of the County west of Stake Point; As a whole,the County is relatively undeveloped. Although located in the San Francisco Bay Area,one of the most populated urban areas of the nation,approximately 25 percent of the County was devoted to urban uses in 1990,while The balance is used for non- urban uses such as agriculture,wetlands,parks,recreation,or general open space and other non-urban uses. Nonurban uses shall also include rural residential and agriculturalstructurm and facilities for public purposes,whether privately or publicly funded or operated,which are necessary or desirable for the public health,safety or welfare or required by State or federal law. None of the land is used for timber harvesting. The amount of land m each major land use category m the County is in Table 3-1. West County Population In 1980 approximately 213,000 people lived in West Countys urbanized areas. By 1990 the population had increased to 2263,000 and by,�000 tie�ix-mulatinn ms 241,02.

Other smaller facilities are scattered throughout the remainder of the East County. SWAM 3-4 �'" 3.Land Use Element 4. (open Space. Agricultural uses, farmland,and particularly grazing land, consume most of the acreage in the East County. Crops are grown on broad coastal terraces and in narrow alluvial stream valleys, while cattle grazing and dry farming occur on the surrounding foothills. Recreation uses in East County include the Delta area and the Antioch shoreline; a recreation facility at Big Break; Black Diamond Mines and the Contra Loma Regional Park;plus others run by the East Bay Regional Park District. 3.6 PLANNED LEVELS OF DEVELOPMENT METHODOLOGY The analytical basis for determining the projected levels of development and land use was used consistently throughout other elements of this General Plan and is a modeling framework and database consisting of the following Elements: o review of relevant data sources,including: of City and County Plans;1980, �rx�?tXl�1990-� Census data; ABAG "Projections 1985, 19879 1990 1992, 1994 ?ff ; various map overlays depicting various envi characteristics;and Contra Costa Land Information System,showing assessor parcel maps with building permit information; .. A.A L16 W111A,11 4 ..ers the ... v defined use of an eare-a'ashand use,empinyment. ttL.IUC .• Year • i .. t fflti o � the County modeling program utilized the above sources for determining exact projects under construction,projects approved,projects proposed,and lists of vacant land and their zoning designation,for both city and County lands;and o projecting to the year 2020-05, the model assigned "default" values to all vacant land uses not covered by projects in the cities and the County, and developed a potential estimate of demand for these land uses. This provided projected population,housing,and employment generation estimates. PROJECTED DEMAND FOR CONVERSION OF LAND USES This Land Use Element and the other elements of the General Plan reaffirm many of the goals and policies of the prior County plan and plan amendments that have been adopted incrementally over the years. The General Plan will accommodate an ultimate population of slightly more than omillion persons. The Growth Management Element, in regulating the timing of development to meet various infrastructure and facility standards,could affect whether the land use conversions set forth in this-the lement actually occur during the horizon of this General Plan. Development contemplated by this Land Use Element,even without possible timing delays caused by implementation of the Growth Management Element,would comply with the 65/35 Land Preservation Standard. Table 3-2 shows the existing and projected population, number of households and employment for the County as a whole fpr 2000 and 2020. SUBAREA DEVELOPMENT SUMMARY The Contra Costa County Land Use Element map, , is included irr�hr-pric-�-t-at the back of this document. Date- The ability to develop under the land use designations shown on this Land Use Element Map could be affected by restrictions contained in the Growth Management Element,and many other factors. As noted previously in Section 3.1, California planning laws advise counties to include incorporated cities within their General Plans,even though a county has land use jurisdiction only in the unincorporated areas. Thus,this General Plan covers all of Contra Costa County,and the following analysis includes the impacts of buildout of the+8-19-city plans. RESIDENTIAL GROWTH The Plan will, subject to compliance with growth management,the 65/35 standard,and other policies and standards, allow a significant amount of new housing development within the Urban Limit Line in the Daugherty Valley and r 131Wjareas and smaller amounts of"in-fill"development in unincorporated Bay Point,Alamo,El Sobrante,Saranap,and other smaller unincorporated places. West Cflnnty In North Richr=4 Inmdreds of acres of vacant industrial land are expected to be developed or redeveloped during and after the pg period,now that completion of a major flood control and y project makes the area more attractive to investors. 3-5 3.Land Use Element Fast caunty Much of the future growth in the County is planned for the-Pittsburg-Antioch-and othr-r-QA14 areas of East Contra Costa Comity.

It should be noted that the job projections included in Table 3-2 assume that only a portion of the vacant lands planned for commercial or industrial uses will be developed during the planning period. The General Plan projections assume that market constraints and other factors will limit the amount of commercial and industrial development that is planned in the fast-growing East Contra Costa area. Thus, some of the job growth is not expected until after the 15-year planning period,during the second or third decades of the.--iextthis century. THE URBAN LIMIT LINE AND LAND USES It is imperative that the reader of this General Plan appreciate the interrelationship between the ULL,the 65/35 standard and the land use designations identified in this Land Use Element. The establisb=nt of the ULL,comrnunity support for which was �d by the voters in their adoption of Measure C- 1990,is an integral feature of this Land Use Element. In general,the purpose of the ULL is twofold: (1)to ensure tion of identified non-urban agricultural,open space and other areas by establishing a line beyond which no urban land uses can be designated during the term of the General Plan,and(2)to facilitate the enforcement of the 65/35 Land Preservation Standard. 3-6 `�" 3.Land Use Element To establish the location of the initial ULL,the County considered a number of criteria and factors. The factors for properties to be considered for location outside the ULL included:(1)land which qualifies for rating as Class I and Class H in the Soil Conservation Service Land Use Capability Classification;(2)open space,parks and other recreation areas;(3)lands with slopes in excess of 26 percent; (4) ; and(5) other areas not appmapfriate for urban growth because of physical unsuitability for development; unstable geological conditions, inadequate water availability, the lack of ' to infrastructure, distance from existing development,likelihood of substantial enviro dal damage or substantial injury to fish or wildlife or their habitat;and other similar factors. No one criterion was necessarily determinative of whether a property was located inside or outside the ULL. Where properties had characteristics that would locate Ihe7n either inside or outside the ULL,the County,based upon the best information available at the time,weighed the competing characteristics and determined the most appropriate location for the property. During the term of the General Plan,properties that are located outside the ULL may not obtain General Plan Amendments that would re-designate them for an urban land use. In addition,those properties outside the Urban Lfinit Line may be subject to various agricultural and open space preservation measures identified in the other portions of the General Plate. These measures could include the following: (1)pemutaing owners of large acre parcels to subdivide and sell off two one-acre parcels from their property that could be developed with one residential unit on each parcel; (2)encouraging*the dedication of open space and conversation (3)implementing a transfer of development rights(TDR)program;(4)requiring payment of an agricultural mitigation fee for conversion of agricultural land;(5)promoting non-urban"tion"agreements between the County and cities to prevent annexation by cities of certain a ' to properties;(6)promoting special legislation for prefer tax ftmftx gent for agricultural and open space lands; and (7)establishiniz an "agricultural soils trust fund" to fiord possible purchase of easements or title to gricult<nal or open space lands. In general,the purpose of ttnese measures is to preserve open space and agricultural lands and contribute to the contirnied economic viability of agricultural property. Inclusion of the measures in the General Plan does not necessarily mean that all or any oir of them is endorsed by the County. Actual in i.01 n Mentation of any of the measures will require fiuther study and analysis and implementation through to zoning measures. Properties that are located inside the ULL would be governed by the land use designations contained in the General Plan. These properties would continue to be subject to the goals,policies and implementation measures of the General Plan as a whole. The fact that a property is located inside the ULL provides no guarantee or implication that it may be developed during the lifetime of the General Plan. Developmertt of property within the ULL would be restricted by the limitations imposed by the County's Growth Management Program,as well as by other General Plan lirnitations. In addition,those properties within the ULL that do not currently have land use designations that would permit urban development would have to apply for and obtain a General Plan Ammidment re-designating the property with a land use designation permitting development Moreover,even if land is developed within the Urban Limit Line,a substantial portion of this land shall be retained for non-urban uses such as open space, parks and recreational uses. These nonurban uses within the ULL shall be considered"nonurban"in monitoring the 65/35 Land Preservation Standard This goal shall be applied within the ULL on a Countywide basis as it may be more or less applicable to various development projects within the ULL. Therefore,the only actual effect of locating a property within the ULL is that a General Plan Amendment may be considered for that property within the term of the General Plan,while no such application would be considered for properly located outside the ULL. CHANGES TO THE URBAN LMT LINE There shall be no change to the ULL that would violate the 65/35 Land Preservation Standard. The ULL will only be able to be changed by a 4/5 vote of the Board of Supervisors after holding a public hearing and making one or more of the following findings based on substantial evidence in the record: (a) a natural or man-made disaster or public emergency has occurred which warrants the provision of housing and/or other community needs within land located outside the ULL; (b) an objective study has determined that the ULL is preventing the County from providing its fair share of affordable housing or regional housing as required by State law, and the Board of Supervisors finds that a change to the ULL is necessary and the only feasible means to enable the County to meet these requirements of State law; (c) a majority of the cities that are party to a preservation agreement and the County have approved a change to the ULL affecting all or any portion of the land covered by the preservation agreement; (d) A minor change to the ULL will more accurately reflect topographical characteristics or legal boundaries; (e) an objective study has determined that a change to the ULL is necessary or desirable to further the economic viability of the east Contra Costa County Airport,and either(I)mitigate adverse aviation related to environmental or community impacts attributable to Buchanan Field, or (ii) further the County's aviation related needs; (f) a change is required to conform to applicable California or federal law;or 3-7 3.Land Use Element (g) a five(5)year periodic review of the ULL has determined,based on the criteria and factors for establishing the ULL set forth above,that new information is available(from city or County growth management studies or otherwise)or cucunistances have changed,wanwWng a change to the ULL. The ULL is shown on Figure 3-1. A larger scale map showing the ULL and any changes to the ULL can be obtained from the County Community Development Department. Table 3-3 shows the estimates of how the initial ULL relates to the 65/35 Land Preservation Standard in terms of acreage. This percentage breakdown of land use translated to the acreage figures within and outside the ULL is provided in Table 3-3. The figures were developed by pbnftrrw readings of the ULL as drawn on the Land Use Maps by the Contra Costa County Conmmnity Development Departrnent They demonstrate that of the 4810 4006 acres in the County, 1684OW acres(35 percent) could be devoted to a xrmllum urban use under the mterplay of the 65/35 standard with the ULL progratY1 This would require future General Plan . The calculations indicate that ffim are about 144,OJS6 acres designated in the Plan for urban use within the ULL,after deducting the existing 4'-,(ft 3=acres of agricultural and open space land inside the ULL. 65/35 T.and Preservation Standard The 65/35 Land Preservation Standard was a component of Measure C - 1990. The standard limits urban development in the County through at least the horizon of this General Plan to no more than 35 percent of the land in the County ..No, and requires that at least 65 percent of all land in the County shall be preserved for agriculture,open space,wetlands,parks and other non-urban uses.(For definitions,see Chapter 3.5) The Urban Limit Line works to enforce the 65/35 Land Preservation Standard and establish a line beyond which no urban land uses can be designated. The standard ensures that both within and outside the ULL, a n of not more than 35 percent urban development could occur in the County, irrespective of potential General Plan Armadmentsm the future. As described above,substantial portions of land to be developed within the ULL will be required for the open space, parks, recreation and other non-urban uses. The 65/35 standard operates on a Countywide basis and therefore includes urban and non-urban uses within cities as well as unincorporated areas. --.

The Plan includes four different single family residential designations, and seven multiple family designations.The single family categories range from a density of rural residences on one-acre lots up to 7.3 homes per net acre. The Plans ofmrltiple family(usually attached housing)designations rage fi�om low density townhouses, is or trader homes at a density of over seven urmts per net acre up to very deme ap neat projects that could codain up to 100 units per acre. A multiple N farrrily designation is also included to describe congregate cane projects at defined densities(senior housing with sorne shaved fac�ities).

Table 34 lists the 32 General Plan land use designations and the densities that are associated with each. The °-�- designations are closely related to the density requirements defined in the County's Zoning Ordinance, and are continuous, without gaps, across the density range. For example,the density requirements of units per net acre for the Single Family Residential-Very Low(0.2-0.9)and Single Family Residential-Low(1.0-2.9)mean that the very low designation will allow for densities ranging from 0.2 units per net acre up to but not including 1.0 units per net acre.

Floor area ratio is calculated by dividing building square footage by lot size. 3-10 3.Land Use Element The densities of the General Plan's residential designations are generally defined in terms of housing units per net acre. Net acreage includes all land area used exclusively for residential purposes, and excludes street.�s,highways, and all other public rights-of-way. Net acreage for residential densities is assumed to constitute 75 percent of gross acreage for all uses,except for the multiple family designations, where it is assumed to comprise 80 percents However, actual measurements used on an application may be based on analysis of the proposed development site plan. When calculating the allowed density of a parcel,readers should keep in mind that unique environmental characteristics may justify a reduced number of units or intensity of use than is normally allowed under the General Plan designation. Notwithstanding this caveat one single-family residential unit is allowed on any existing,legally created lot designated in all residential and open space categories. Variances from the ' ' lot size and dimensional requirements are provided for in the County Zoning Ordinance,in accordance with State law. The commercial and industrial General Plan categories are defined in terms of floor area rano (FAR). The FAR is calculated by dividing the square footage of a building by the square footage of its lot. Thus, a structure composed of 10,000 square feet constructed on a 20,000 square foot lot has a FAR of 0.5. Table 3-5 satmudzes the relationship between the land use designatiions used in this General Plan and the zoning districts defined in the Cotes current Zoning Ordinance. The table outlines which specific zoning districts are already consistent with each General Plan designation and those which might be considered consistent with the Plan category,dept on the particular use.

The County's Planned Unit(P-1)zoning district could be considered consistent with any of the General Plan designations. When considering standards referenced in Table 3-5 and in the category definitions,the P-1 district is intended to allow flexibility in the relationship of various buildings, structures, lot sizes, and open spaces while ensuring compliance with the General Plan and County codes and standards that protect public health,safety and the -- general welfare of the County. The County Community Development Department shall determine plan compliance to standards found in this plan, without exceeding the total density or intensity of the project site as a whole, as specified in the General Plan. The County Ordinance Code specifies a range of uses which are allowed by right or through the granting of a land use permit within each zoning district. A major miplernentation measure included in this plan calls for the County Ordinance Code to be reviewed and revised to ensure that the provisions of the code conform to the intent and spirit of the Plan. However,as a matter of County policy,the staff reports prepared for all applications shall discuss whether the application complies with the spirit and intent of this updated General Plan. In instances where consistency between allowable uses under current zoning and the General Plan cannot clearly be determined(due to scope,scale or use),use permit applications shall either be denied or directed to apply for a rezoning. RESIDENTIAL USES The General Plan map utilizes ten designations of residential use, four of which describe single family densities and --. seven describe multiple family densities. The abbreviation in parentheses following the name of each land use designation is a code used on the General Plan land use map to identify the areas so designated. The following two criteria define residential land use categories: -- o housing units per net acre (excluding the area required for local streets and other public uses, which is assumed to consume approximately 25 percent of the gross single-family and 20 percent of the multi-family residential area);and - o the population density range(persons per net acre)which is associated with the category. The prohibitions on attached or detached structures found within the residential plan categories can be modified if found to be appropriate,to comply with the General Plan intent,and to respond to site environmental factors but only if considered through use of the Planned Unit District Zoning process. It should be noted that the Planned Unit Development ordinance is intended to provide flexibility of site design, building massing, setbacks, height, etc. As indicated in Table 3-5 and discussed above, Planned Unit Development projects may be approved in any of the land use categories,provided that the overall density of the project is within the range specified in that category. The residential land use designations are as follows: a. Single-Family Residential-Very Low Density(SV). This designation allows a maximum of up to 0.9 single family units per net acre. No maximum site area per unit is defined. With an average of 2.5 persons per household, population density would normally range between one to three persons per acre.

Secondary uses generally considered to be compatible with very low density homes may be allowed,including home occupations, small residential care and childcare facilities, churches and other similar places of worship, secondary dwelling units and other uses and structures incidental to the primary uses. b. Single-Family Residential-Low Density(SL). This designation allows a range of 1.0 and 2.9 single family units per net acre. Sites can be as large as 43,560 square feet .: Unique en ' nental characteristics of a parcel may justify larger lot sizes. With an average of 2.5 persons per household,population densities would normally range from about two to about 7.5 persons per acre. Primary land uses which shall be perrrritted in this designation include detached single family homes and accessory structures. Secondary uses generally considered to be compatible with low density homes may be allowed,including home occupations, small residential care and childcare facilities, churches and other similar places of worship, secondary dwelling units,and other uses and structures incidental to the primary uses. 3-12 '� 3.Land Use Element C.

The Willow Pass Road Commercial Mixed-Use designation("M-5"on the Land Use map)has been applied to properties on the south side of Willow Pass Road,west of Bailey Road in the Pittsburg/Bay Point BART Station Area Specific Plan area. The intent of this designation is to create a Neighborhood Com niercial District as a focal point of the Bay Point Comnwnity. It is further intended that the area should be pedestrian-oriented district with adequate parking,with its placement subservient to the shopping uses' orientation to Willow Pass Road. Uses within the area are intended to serve residents who live nearby or are passing by from the greater neighborhood. E Bay Point Residential Mixed-Use(M-6). The Residential Mined-Use designation("M-6"on the Land Use map)has been applied to properties in the 3-17 3.Land Use Element southeast quadrant of the State Route 4/Bailey Road intersection in the Pittasburg/Bay Point BART Station Area. The intent of this designation is to encourage moderately high density,residential development which takes advantage of the area's close proximity to both the BART Station and Ambrose Park. Limited commercial uses are intended as secondary to the residential development and oriented to providing goods and services to neighborhood residents and visitors to Ambrose Park. 90 Pittsburg/Bay Point BART Station Area Mixed-Use(M-7). MUM The Pittsburg/Bay Point BART Station Area Mixed-Use designation("M-7" on the Land Use map)has been applied to property on the southwest quadrant of the State Route 4/BaileyRoad intersection in the Pittsburg/Bay Point BART Station Area,as described in the plans adopted by the City of Pittsburg.

Up to 680,000 square feet of retail/office/civic uses could be allowed in the Village Center. i. Montalvin Manor Mixed Use(M-9) The Montalvin Manor Mixed Use designation applies to two sites located at the intersection of Tara Hills Drive and San Pablo Avenue a site consisting of one parcel at the northeast comer of the intersection and a site consisting of two parcels at the southeast comer of the intersection. A range of neighborhood retail,residential,and office uses are permitted in this designation to stinmlate the upgrading and redevelopment of the properties. The site at the northeast comer of the intersection of Tara Hills drive and San Pablo Avenue is one parcel(APN: 403-030-005)comprisi approximately 13 acres. The mixed use designation is intended to encourage the mix of Ing %W both residential and neighborhood retail uses on this site. Residential uses could include a range of multi-family or single-family residential uses,including but not limited to a mbilehorne park and senior housing. As a general guide the permitted density for multi-family residential development on this site should be within the range of 12 to 20.9 units to the acre,comparable to the Multiple Family Residential—Medium Density(MM)designation under the General pim It is acknowledged that the site is bisected by Garrity Creek a riparian corridor that presents potential constraints to site development which may further limit development density. To the extent feasible,the development of neighborhood retail on the site should be oriented toward San*Pablo Avenue. As a general guide --- the permitted density for single family residential development on this site shall be comparable to the single family high designation in the range of 6,000 to 7,000 square foot lots. I 3-18 3.Land Use Element The site at the southeast comer of the intersection Tara Hills Drive and San Pablo Avenue is approximately 3 acres on two parcels (APN: 403-202-011/012). The mixed use designation is intended to encourage the mix of both residential and neighborhood retail uses on this site. Residential uses could include a range of multi-family or single-family residential uses. As a general guide the permitted density for multi-family residential development on this site should be within the range of 7.3 to 11.9 units to the acre,comparable to the Multiple Family Residential—Low Density(ML)designation under the General Plan. To the extent feasible,the development of neighborhood retail on the site should be oriented toward San Pablo Avenue.

These include open space,agricultnl,and recreational uses, as well as public/serni-public uses such as schools;public offices;highways and major flood control rights-of-way;and railroads. These use designations generally comprise non-urban uses under the 65/35 Land Preservation Standard. (b) Public and Send-Public. As the title implies, the "Public and Semi-Public" designation includes properties owned by public governmental agencies such as libraries,fire stations,schools,etc.This designation is also applied to public transportation corridors (freeways, highways, and BART), as well as privately owned transportation and utility corridors such as railroads, PG&E lines, and pipelines. The largest properties in this category are those of the U.S.Naval Weapons Station in Concord and Port Chicago. A wide variety of public and private uses are allowed by this General Plan category. However, the category. construction of private residences or private commercial uses, and the subdivision of land, are not considered compatible with this designation. (c) Agricultural Lands. This land use designation includes most of the privately owned rural lands in the County, excluding private lands that are composed of prime soils or lands that are located in or near the Delta.Most of these lands are in hilly portions of the County and are used for grazing livestock,or dry grain farming.The category also includes non-prime agricultural lands in flat East County areas,such as outside Oakley,which are planted in orchards. Some of the Agricultural Lands east of Oakley and Byron are included in the 100-year flood plain,as mapped by the Federal Emergency Management Agency(FEMA). The purpose of the Agricultural Lands designation is to preserve and protect lands capable of and generally used for the production of food, fiber, and plant materials. The title is intended to be descriptive of the predominant land-extensive agricultural uses that take place in these areas, but the land use title or description shall not be used to exclude or limit other types of agricultural, open space or non-urban uses such as landfills, except as noted below in the descriptions of"Agricultural Core," "Delta Recreation and Resources," "Watershed," "Parks and Recreation," and "Open Space." The maximum allowable density in this category is one dwelling unit per 5 acres. The uses that are allowed in the Agricultural Lands designation include all land-dependent and non-land dependent agricultural production and related activities. In addition,the following uses may be allowed by issuance of a land use permit,which shall include conditions of approval that mitigate the impacts of the use upon nearby agricultural operations through the establishment of buffer areas and other techniques: 0 facilities for processing agricultural products produced in the County such as dairies, rendering plants,and feed mills; 0 commercial agricultural support services which are ancillary to the agricultural use of a parcel, such as vete i i ,feed stores,and equipment repair and welding;and 0 small-scale visitor serving uses including small tasting rooms,stands for the sale of products grown or processed on the property, guest or "dude" ranches, horse training and boarding ranches, improved campgrounds, and"bed and breakfast" inn of five or fewer bedrooms which are on lots of 20 acres or more,extensive recreational facilities and private retreats. The following standards shall apply to all uses allowed in the Agricultural Lands designation: (1) Any subdivision of lands shall include conditions of approval which conform with the requirements of the "Ranchette Policy," which is outlined in the "Agricultural Resources" section of the Conservation Element(Chapter 8);and 3-19 3.Land Use Element (2) Residential and non-residential uses proposed in areas of special flood hazards, as shown on FEMA maps, shall conform to the requirements of the County Floodplain Management Ordinance(County Ord.#87-45)and the further requirements outlined in the"Delta Recreation"section(d)(5)below. (d) Agricultural Core. This designation applies to agricultural lands that are composed primarily of prime (Class I or II) soils in the Soil Conservation Service Land Use Capability Classifications,which are considered the very best soils for farming a wide variety of crops. Lands designated as Agricultural Core are located in East County outside the ULL to the east, south, and west of the City of Brentwood.Much of the land in this designation is under active cultivation of intensive row crops, such as tomatoes and other vegetables. A portion of the Agricultural Core lands are included within the 100-year flood zone, as identified by the U.S. Federal Emergency Management Agency(FEMA). The purpose of the Agricultural Core designation is to preserve and protect the farmlands of the County which are the most capable of,and generally used for,the production of food,fiber,and plant materials.Agricultural operations in the Agricultural Core shall, in accordance with Measure C - 1990, be protected by requiring a higher minimum parcel size than the Agricultural Lands designation, to attempt to maintain economically viable,commercial agricultural units.The creation of small uneconomical units will be discouraged by land use controls and by specifically discouraging minor subdivisions and"ranchette"housing development. The uses that are allowed in the Agricultural Core designation are the same as those allowed, without the issuance of a land use permit,in the Agricultural Lands designation,specified above. Except for wineries and olive oil mills, each of which typically includes tasting rooms and a limited retail sales area,none of the uses described as conditional uses in the Agricultural lands designation are considered appropriate in the Agricultural Core designation. A land use permit for a winery in conjunction with a planted vineyard,or olive -- oil mill in conjunction with a planted orchard, may be issued for a parcel of 5 acres or greater and upon a determination that such agricultural processing facilities and their accessory uses will not conflict with the goal of preserving and protecting the prime farmlands in the Agricultural Core. This Plan discourages the NORM placement of public roadways or new utility corridors which would adversely affect the viability of the Agricultural Core if economically feasible alternatives exist. Residential uses are allowed in the Agricultural Core according to the following standards (in accordance with Measure C- 1990): (1) the maximum permitted residential density shall be one unit per 40 acres; (2) subdivision of land which would create a cluster of"ranchette"housing is inconsistent with this plan;and am (3) residential and non-residential uses proposed in areas of special flood hazards,as shown on FEMA maps, shall conform to the requirements of the County Floodplain Management Ordinance(County Ord.#87- 45)and the further requirements outlined in the"Delta Recreation and Resources"section(d)(5)below. (e) Delta Recreation and Resources. This land use designatiion encompasses the islands and adjacent lowlands of the San Joaquin-Sacramento Delta, --- excluding Bethel Island and the c 'ty of Discovery Bay which have separate land use designations on the Land Use Map.Most of the lands designated Delta Recreation and Resources are within the 100-year flood plain mapped by FEMA, which means that the area is subjected to periodic flooding. Many of the Delta islands, and the tracts adjacent to the Delta,are currently in agricultural production of dry grains and other special crops suited to the soils and climate,such as magus.There are limited public water or sewer services currently available to the area. The serious flooding danger in the area is due to the possibility that bay and river waters will overtop the existing levees ...m during periods of storms or other high water,as well as the possibility that portions of the earthen levees may fail entirely during stomas or eardiquakess resulting in the iinuydation of whole islands or tracts.The flooding danger is exacerbated by The effects of subsidence(sHdng of Delta islands)and the rising of global sea waters caused by the"greenhouse effect"In recent years,ening 1973,1980,1983,and 1986 one or more Delta island levees failed or were oveitapped,and some of these were surrnr breaks that did not occur at a time of high storm runoff.Some islands in the Delta have been flooded two or three times since 1980. 1 Tuner loner hlaand-in adiace�,t�n`kms rn jin Comity-fltW in the.s tmn .r of 2(�_ Additionally, lands within this designation include lands with valuable wildlife habitat, some of which MOW support species of ecological value to the County and the State.These areas are an important component of the Pacific Flyway,a major waterfowl migration route in North America. 3-20 3.Land Use Element Public preservation of portions of these resources is encouraged by this plan.Private utilization of the resources for hunting and fishing is appropriate,if the activities do not harm the long-term resource value of the Delta. Due to their proximity to the Delta waterways,these lands have potential recreational value.The purpose of the Delta Recreation and Resources designation is to balance the recreational opportunities of the area against the need to allow only low intensity uses which will not subject large numbers of residents or visitors to flood dangers.Agriculture and wildlife habitat is to be considered the most appropriate uses in the area,with limited recreation uses allowed which do not conflict with the predominant agricultural and habitat uses. The primary uses that are allowed in the Delta Recreation and Resources designation are those agricultural production and processing activities allowed in the Agricultural Lands designation,listed in section(b)above. Additional uses that may be allowed through the issuance of a land use permit include: marinas, shooting ranges,duck and other hunting clubs,campgrounds,and other outdoor recreation complexes. Conditional uses allowed in the Delta Recreation and Resources designation shall be limited to those low-to medium-intensity establishments that do not rely on urban levels of service or infrastructure,i.e.,a public water or sewer system,and which will not draw large concentrations of people to flood-prone areas. Uses allowed within areas designated for Delta Recreation and Resources shall be subject to the following standards: (1) the maximum permitted residential density shall be one unit per twenty acres; (2) all recreational uses shall be accessible by a publicly maintained road; (3) any subdivision of lands shall include conditions of approval which conform with the requirements of the "Ranchette Policy," which is outlined in the "Agricultural Resources" section of the Conservation Element; (4) development shall not be on lands designated by FEMA as flood prone until a risk assessrmnt and Other technical studies have been pn and have shown that the risk is acceptable; (5) all approved entitlements (land use permits, tentative, final, and parcel maps, development plan permits,and variances)and ministerial pen-nits(building and grading permits)shall conform to the requirements of the Floodplain Management Ordinance (County Ord. #87-45), which are incorporated into this General Plan by reference; (6) all entitlements shall include conditions of approval which require that a "flood-prone area" notification statement be included in the deeds for all affected properties. The same notification statement shall be recorded on the face of all subdivision maps, along with the specific elevations that will be required of all new building pads and habitable floors;and (7) dock and marina standards as described in policy 3-48. Watershed. Aims meted"Watershed"in this General Plan include nmch of land owned by the two major water suppliers in the County,the East Bay Municipal Utility District(EBMUD)and the Contra Costa Water District(CCWD). EBMUD property designated as "Watmsbed!' smmunds the Lafayette,Briones, San Pablo,and Upper San Leandro Reservoirs (which are in a separate"Water"designation). Offiff EBMUD lands designatedin this designation are located north and south of the Caldecote Tunnel and along Pinole Valley Road. CCWD lands placed in the "WatenW1 '21I.L category inchide properties acquired for The pi ?osed Los Vaqueros reservoir in the southeastern portion of the County. In order to safeguard the public water supplies stored in the reservoirs, only a very limited number of uses are allowed in "Watershed" areas. These uses include extensive agriculture,primarily grazing of livestock; intensive agriculture that does not rely upon pesticides or other chemical fertilizers, such as Christmas tree fanning; passive, low intensity recreational uses such as hiking and biking, as well as small-scale commercial uses that support picnicking,boating,and fishing activities on the adjacent reservoirs. (g) Open Space. This General Plan designation includes publicly owned,open space lands which are not designated as"Public and Semi-Public," "Watershed," or "Parks and Recreation." Lands designated "Open Space" include, without limitation,wetlands and tidelands and other areas of significant ecological resources,or geologic hazards. 3-21 3.Land Use Element The "Open Space" designation also includes privately owned properties for which future development rights have been deeded to a public or private agency. For example, significant open space areas within planned unit developments identified as being owned and maintained by a homeowners association fall under this designation. Also included are the steep, unbuildable portions of approved subdivisions which —" may be deeded to agencies such as the,EBRPD but which have not been developed as park facilities. Other privately owned lands have been designated as"Open Space"consistent with adopted city General Plans. The most appropriate uses in "Open Space" areas involve resource management, such as maintaining critical marsh and other endangered habitats or establishing "safety zones" around identified geologic hazards. Other appropriate uses are low intensity,private recreation for nearby residents. The construction of permanent structures, excluding a single-family residence on an existing legally established lot, not GUMMM oriented towards recreation or resource conservation, is inconsistent with this open space designation. One single family residence on an existing legal lot is consistent with this designation. (h) Parks and Recreation. " The "Parks and Recreation" designation includes publicly-owned city, district, County and regional parks facilities,as well as golf courses,whether publicly or privately owned. Appropriate uses in the designation are passive and active recreation- oriented activities, and ancillary commercial uses such as snack bars, and restaurants. The construction of new privately owned residences or commercial uses,and the subdivision of land,is inconsistent with this General Plan designation. (i) Water. This designation is applied to approximately 68 square miles of water in the San Francisco-San Pablo Bay and Sacramento-San Joaquin River estuary system which is within the County. The designation is also ...ft applied to all large inland bodies of water such as reservoirs. Uses allowed in the"Water"designation area include transport facilities associated with adjacent heavy industrial plants,such as ports and wharves;and water-oriented recreation uses such as boating and fishing. --. The construction of new residences or commercial uses and the subdivision of land is inconsistent with this General Plan designation. (j) Landfill "LF" designates sites for public or private landfills. Landfills and related uses are allowed in LF areas. A use permit shall be required to develop a landfill. Uses in any buffer areas within an LF designation shall ANON be limited to landfill-related uses,open space uses,and agricultural uses. Prior to landfill development,open space or agricultural uses allowed by the AL designation are allowed in LF areas. After a landfill is closed, these AL uses, plus monitoring and other necessary or desirable post-closure activities,are allowed. To satisfy the re for building intensity and population density ,the following provisions apply to areas designated for landfills:(a)one landfill shall be allowed within each LF area;(b)no new residential units shall be allowed; and(c) accessory buildings shall be limited to a of three stories in height(excluding towers or an�relating to landfill operation). These provisions are R,and the actual height of any landfill facilities shall be set forth in the use permit and accompanying plans. The specffic dimensions of each landfill will depend upon the features of the designated site,and must be determined in considering a use permit for the landfill. The LF designation also implements Section F(2) of the Board of Supervisors' 65/35 Land Preservation Plan,approved by the County voters as Measure C in November 1990. Section F(2)provides that facilities MEW for public purposes are a non-urban use allowed outside the Urban Limit Line. 3.8 LAND USE GOALS,POLICIES AND IMPLEMENTATION MEASURES GOALS The following broad goals form the basis from which the County's land use policies and implementation measures, presented later in this chapter,are derived.In the following goals,policies and implementation measures,note that when won" the word"urban"is employed(as in the phrase"urban development"and"urban uses"),the broad definition of the word is intended. This broad definition is the definition of Measure C- 1990 used to distinguish between the maximum of 35 3-22 3.Land Use Element percent of the County land that can be used for urban development and the 65 percent minimum of land in the County that must be preserved for agriculture,open space,wetlands,parks and other non-urban purposes. This broad definition of"urban" is in contrast to the more restrictive use of the word "urban" in the Growth Management Program,which is included in Chapter 4. These more restrictive definitions were used in Measure C- 1988 solely for information and guidance in applying traffic service standards for growth management. 3-A To coordinate land use with circulation, development of other infrastructure facilities, and protection of agriculture and open space,and to allow growth and the maintenance of the County's quality of life. In such an environment all residential,commercial,industrial,recreational and agricultural activities may take place in safety,harmony,and to mutual advantage. 3-B To provide opportunities for increasing the participation of Contra Costa County in the economic and cultural growth of the region, and to contribute to, as well as benefit from, the continued growth in importance of the Bay Region and the State of California. 3-C To encourage aesthetically and functionally compatible development which reinforces the physical character and desired images of the County. 3-D To provide for a range and distribution of land uses that serve all social and economic segments of the County and its subregions. 3-E To recognize and support existing land use densities in most communities, while encouraging higher densities in appropriate areas,such as near major transportation hubs and job centers. 3-F To permit urban development only in locations of the County within identified outer boundaries of urban development where public service delivery systems that meet applicable performance standards are provided or committed. 3-G To discourage development on vacant rural lands outside of planned urban areas which is not related to agriculture,mineral extraction,wind energy or other appropriate rural uses;discourage subdivision down to . 0 parcel size of rural lands that are within, or accessible only through, geologically unstable areas; and to protect open hillsides and significant ridgelines. 3-H To adopt and implement an innovative Countywide Growth Management Program which effectively links land use policy with transportation and other infrastructure improvements. 34 To coordinate effectively the land use policies of the County General Plan with those plans adopted by the cities and special service districts. 34 To encourage a development pattern that promotes the individuality and unique character of each community in the County. 3-K To develop a balance between job availability and housing availability with consideration given to wage levels, commute distance and housing affordability.The individual characteristics of the several subregions of the County and their interaction with other regions shall be considered when establishing criteria for delivering that balance. 3-L To safeguard the County's obligations to provide its fair share of safe,decent and affordable housing. 3-M Protect and promote the economic viability of agricultural land. 3-N To coordinate effectively the policies of the Land Use Element with appropriate Local Agency Formation Commission(LAFCO)determinations. POLICIES Countywide The following are broad, Countywide policies which apply to all probes. More detailed development policies for specific areas in the County are found in the"Local Plan Policies"section at the end of this chapter. Jobe./nnugging Bolan 3-1.

Water-oriented recreation uses shall be permitted in East County provided that such development is compatible with the Delta's unique ecology. ,_,,, IMPLEMENTATION MEASURES The following specific measures should be implemented in order to carry out the land use goals and policies outlined in this chapter. The major implementation measure for this plan is a Growth Management Program,a 65/35 Preservation Standard and a ULL. The programs are described earlier in this Land Use Element(see Chapter 3.6)and in Section 4, Growth Management Element. (To the extent implementation measures referenced earlier in Chapter 3.6 are identified, they are incorporated into this list of land use implementation measures.) wx- Overall Measures 3-a.

The two areas differ with respect to soils, topographic and geographic conditions,and levee stability. As a result,different development and planning considerations must be given to each area. The onrisland area consists of wear organic soils that underlie the perimeter levee system,provides limited opportunities for evacuation in the event of a levee failure, is generally below sea level and subsiding, and provides limited opportunities for safe disbursement of flood water because it is a small island closed by levees. In the off-island area,on the other hand, the soil is sandy and less subject to subsidence, the elevation is higher,the levee system is in an improved condition and not as long,there are several evacuation alternatives,it is part of the land.and disbursements of flood waters are not artificially contained such that internal systems around new development will not adversely affect existing residences and structures in the flood plain. The concept for the Bethel Island Area is to preserve and enhance the rural and recreational quality of the unique area, while providing opportunities for residential and growth tied to water-oriented recreation. The following policies shall guide development in the Bethel Island Area: Ate „ , 4....,, The approval of new development shall be li'nited to 2,909 primarily recreation-oriented units in the off-island area(i.e.,3,000 additional units including the 91 units already approved,but not yet built). 3w7+3-55- residential development in the on-island area shall be limited at this time to approved development and one dwelling unit per parcel. 4=1+3'5156._„ Additional residential density in the on-island area may be considered through subsequent amendment at the discretion of the Board of Supervisors,provided at least the following are accomplished: (a) a financing mechanism is fiflly and completely assured for improvements to the entire perimeter on-island levee system; (b) the levee improvement plans are approved by Bethel Island Municipal Improvements District and the Army Corps of Engineers;and 3-31 3.Land Use Element Nano (c) subsidence,as well as impacts on wetlands,are adequately mitigated. _3-57. Levee breaches on-island are prolubitied unless the entire perimeter levee is urroved to Amry Corps of B*n" standards. ,.._ 3=7*3-58. Levee breaching off-island shall be permitted on a project-by-project basis and shall only be allowed subject to the Army Corps of Engineers approval. -�3-59. Any internal levees must meet Army Corps of Engineers'standards. New construction must be set back from levee centerlines a ' ' of 100 feet unless adequate substantiation for reduction is approved by RD-799 or BIlVIID. New construction not protected by certified levees must meet FEMA standards. Stilt residential structures shall be allowed only on the basis of one unit per existing parcel. Such elevated structures shall not be allowed in any new subdivisions. 3-7_.3-611. -The off-island and on-island areas can develop 100,000 square feet of commercial development and 500 hotel rooms,consistent with FEMA standards. -.3-62. Marine and waterfront facilities will require a use permit to address site-specific aquatic and other issues such as wetlands,water quality,public access,and the Delta's carrying capacity for such facilities in the Bethel Island .... Area. 3=81-.3-6-3. To retain the characteristics of Bethel Island that make it an unique place in the Delta with its own separate identity,development shall be limited to a low overall density,and open space buffers shall be required. In addition, -- agricultural,open space,and wetland areas,along with rare plant corm amities,shall be preserved and protected. `ti-�. Residential development on Agricultural Lands,to the extent permitted beyond one unit per parcel in the off-island area,shall be clustered with development rights on the undeveloped land dedicated to the County. -- 3�'R -"�- A_Protection Fee shall be imposed on each new residential unit in the Bethel Island Area to acquire development rights on agricultural lands, open space or wetland areas, or to provide financing for farmers to continue agricultural production. Priority for the acquisition of open space and wetlands shall be given to the on-island area. Additional funding sources shall be explored to supplement or replace the Protection Fee. 3-94-3-66, New development in the Bethel Island Area must comply with an improved financing plan for infrastructure improvements.

Many of the specific policy statements of this plan support the concept of allowing for multiple uses, compatible with the predominantly agricultural watershed and public purposes of the area. The policies stress the need to preserve designated agricultural lands for agricultural use, and also to allow certain other uses in the area,such as wind energy farms,mineral extraction,and reservoirs. 3-87-3-68. The Southeast County area is almost exclusively planned for agricultural, watershed, or public purposes. New land uses within this plan area should be limited to those which are compatible to the primary agricultural and watershed purposes of the area (farming, ranching, poultry raising, animal breeding, aviaries, apiaries, horticulture, floriculture and similar agricultural uses and structures) and consistent with the multiple use philosophy enumerated by this plan. Subject to specific project review and the policies listed within this plan, the following uses are generally consistent with the planned agricultural areas: (d) Public and private outdoor recreational facilities; (e) Dude ranches,riding academies,stables; (f) Wind energy conversion systems; (g) Single family residences on larger lots; 3-32 "" 3.Land Use Element (h) Mineral resources quarrying; (i) Oil and gas wells; (j) Pipelines and transmission lines;and (k) Veterinarian offices and kennels.

Southeastern Contra Costa County contains a range of natural and cultural resources which warrant special recognition in the General Plan. Mineral and meteorological resources exist which have the potential to be developed as additional uses within this essentially agricultural area. Multiple uses of the land which assist in its long term protection as an agricultural area are to be encouraged. Policies regarding these specific natural and cultural resources are briefly summarized below. However, a more detailed discussion and additional policies should be referred to in other elements of this General Plan,separated into the following topics: 0 wind turbine developnwnt or wind energy"farms"(policies are found in the Conservation Element); 0 mineral resource areas(policies are found in the Conservation Element); 0 archaeological and wildlife resources(policies are also found in the Conservation Element); 0 Contra Costa Water District reservoir(s) planned in this area (policies are found in the Public Facilities/Services Element); 0 the East Contra Costa County Airport(policies are found in the Transportation and Circulation Element); 0 existing and planned recreation uses in the area(policies are found in the Public Facilities/Services Element); 0 general circulation uses(policies are found in the Transportation/Circulation Element);and 0 Policies and implementation measures regarding the wildlife and archeological resources of the area are included in the Conservation Element. The southeastern portion of the County is blessed with archaeological and wildlife resources which are unique and worthy of long term protection and preservation. While in certain portions of the planning area multiple uses of the land may conflict with the need for environmental protection and enhancement,there are other areas where multiple use may reinforce preservation. As a practical matter,it should be recognized that historically it has been the agriculturalists who have protected the unique environmental resources of the area. Their continued efforts in this regard are critical to the long range preservation of the area's resources. +- 4W-.3-70. The California Energy Resources Conservation and Development Commission has identified the Altamont Pass area, including the south-eastern portion of Contra Costa County,as an area with high wind energy potential. The"Wind Energy Resources"section of the Open Space/Conservation Element contains a map that depicts the generalized boundaries of the wind energy resource area in Southeast County, based on materials developed for the State Energy Commission. The map identifies those areas that experience average wind speeds of at least 15 mph at an altitude of 70 feet above the ground. The same section includes specific policies that govern new wind turbine development in the County. Clusters of wind turbines generate a certain amount of noise which could be a nuisance if new subdivisions or residences are allowed immediately adjacent to the existing turbines or on properties already approved for wind turbines. New residential uses should be discouraged within the wind energy areas.If wind farms become obsolete or are removed in the area, these policies should be reviewed through a subsequent General Plan Amendment. Wind farm uses are to be considered appropriate within the resource area or along the periphery of the wind energy resource area,subject to a careful review of the environmental m4mcts of specific wind farm proposals. A=W3-71-_,....__Within Southeast Contra Costa County there is a geological deposit of dornegine sandstone located just southerly of Camino Diablo and easterly of Vasco Road. This area is further discussed and mapped in the"Mineral Resources"section of the Open Space/Conservation Element. Limited residential or ranchette development of these mineral properties may be appropriate,but residential use shall be identified as secondary to mineral operations and will not be allowed to preclude the full 3-33 3.Land Use Element utilization of identified mineral resources. Any nearby residential use will be permitted conditionally after recognizing the probable expansion of mineral operations and accepting the possible nuisance and inconvenience associated with mineral operations. 3�_�-72._ Public agencies are in the process of acquiring substantial portions of thepA5 area to serve the needs of the growing population of the East Bay. Two major public works projects have been area that n-arst be= reflected in this plan m nendi- mt.-the propos East Contra Costa County Airport and the Las Vaqueros Reservoir. Each is discussed further in the Circulation Element and the Public Facilities/Services Element,respectively. The general location of the airport is shown on the land use element plan map. As the airport project proceeds, land developments in the area must take into account safety, noise, aviation easements, and preservation of the area's agricultural and biological resources. . btfild.!"a-a'vaqtleros- R The district Board of Directors.bas decided t JL e or eiistiLiv.

The historic significance of the Byron Hot Springs site is acknowledged,the rehavilitation of buildings of historic value at the Byron Hot Springs site and the re-estab i sI -ent of the historic suse of the buildings as a hotel and spa are supported. The rehabilitation of the historic buildings on the Byron Hot Springs site should occur in a manner that is both consistent with other General Plan policies and compatible with the operation of the nearby Byron Airport,as reconmwnded in the ALUC compatibility Plan. Implementation of this policy should occur through a discretionary permit review process. Any proposal for the development of a larger resort complex on the Byron Hot Springs site,which may include the incidental rehabilitation of historic buildings,should be undertaken in the -- context of existing General Plan policies. 3-74,--3-93.. This plan further recognizes that if a reservoir or reservoirs are built, that the Contra Costa Water District or other agencies may be required to construct additional secondary construction and access roads on these lands in order to serve their facility. 3-75= - The Southern Pacific railroad provides rail service through Brentwood and Byron. No change in status is anticipated in this plan amendment. However,the railroad right of way does provide the potential for a recreational trail route and for construction of future pipelines. POLICIES FOR THE BAY POINT AREA T.and Ike 3-76, 3- --The following policies shall guide development in the Bay Point area: (a) Upgrade comiraanity appearance by encouraging development of new uses to replace antiquated developn=ts. (b) Provide for well designed projects and limited vehicular access to traffic arterials through the assembly of small parcels of land along Willow Pass Road. .saw (e) Discourage new areas or expansion of strip commercial development in the community except as provided in this plan by the Willow Pass Mixed Use Corridor. (d) Achieve and maintain a healthy environment for people and wildlife,that sizes health hazards and disruptions caused by the production,storage,transport and disposal of toxic materials. (e) A Redevelopment Plan for the Bay Point area was adopted by the Board of Supervisors in December,1987. All development proposals should be reviewed by,and coordinated with,Redevelopment Agency staff to ensure compatibility with the Redevelopment Plan. Additionally, involvement with the redevelopment process will allow the County to coordinate concurrent development proposals and to possibly facilitate the construction of public irr�roven=ts that will further the goals of the Redevelopment Plan.

Existing drainage facilities are antiquated and inadequate. Modifications to existing road design and access points would be desirable to handle greater traffic loads. Given these parameters, an incremental uncoordinated approach to development would probably fail to safeguard community interests. Therefore, this plan supports the assembly of land designated for multiple family residential uses in sufficient acreages to make feasible the provision of a quality residential environment and adequate infrastructure to handle drainage and traffic concerns. Those projects that meet these objectives will be eligible for the maximum housing units within the range of the applicable density category. -3-7 -3-98.---The following development standards shall be applied to projects proposed in the Willow Pass Road Mixed Use Corridor MI 14): (a) access to parcels along Willow Pass Road should be ed and should be from secondary roads whenever feasible; (b) development of shared access with uses on abutting properties should be considered at the time of project review; (c) the assembly and consolidated development of frontage parcels is encouraged by this designation; (d) control on the placement design, number, and size of signs should occur during project review and should be adequate to inform the community of the farm's identity without being visually disruptive;and (e) the County shall consider the adoption of a streetscape plan for Willow Pass Road including, if appropriate, revision to existing precise alignment plans.

Particularly vulnerable areas should be avoided. Slopes over 25%are generally not suited for conventional cut and fill pad development; 3-45 3.Land Use Element (b) Where flood control and drainage works are required along natural water courses, special consideration should be given to using innovative means of retaining the natural appearance of the waterway,and preserve the vegetation and wildlife it supports; (c) Conservation of the scenic beauty of the planning area requires restoration of natural contours and vegetation after grading and other land disturbances, and the design of public and private projects to minimize damages to significant trees and other visual landmarks; (d) Public facilities for outdoor recreation should remain an important land utilization objective in the community, to promote high visual quality, air quality maintenance, and to enhance outdoor recreation opportunities of all residents;and (e) Extreme topographic modification,such as filling in canyons or removing hilltops is to be avoided. Clustering and planned unit development approaches to development are encouraged. All future development, whether large or small scale, should be based on locating safe and suitable sites for buildings, roads and driveways. Edwards Canyon is very sensitive to erosion and siltation problems and should be given special protection. Scenic Waterways are watercourses which receive use by fishing and recreational boat traffic and traverse areas of significant scenic quality. The scenic waterway designation applies to the waterway and its shoreline. -"1-!69.The shoreline and hills along Carquinez uinez Strait between Crockett and Martinez constitute one of q the few undeveloped coastal areas in the East Bay. The scenic beauty of the area enhances, and is complemented by, the historic town of Port Costa. Preservation of this resource through the establishment of a recreation area is encouraged by this plan. _3-.1F .--Crockett has an abundance of charming Victorian buildings. The special scenic and historic qualities of the town should be reflected in a sensitive approach to rehabilitation of these buildings. The structures listed below have been identified as local historic places, reflecting their historic and cultural importance to the community. It is a policy of this plan that the following places should be protected and their historic qualities should be preserved and enhanced: - (a) the American Legion Hall at Pomona and Alexander Streets; (b) the Rolph Park Monument at Pomona Street and Rolph Park Drive; (c) the Railroad depot on Loring Avenue; (d) the Crockett Auditorium on Pomona Avenue; (e) the Episcopal Church on Pomona Avenue; (f) the C&H Company House and Guest house in Crolona Heights; (g) the Crockett Library on Loring Avenue; (h) the Edwards Homestead;and ._ (i) the Loring Road Victorians. - 3-311.17 --Devel ment of the Pointe Crockett General Plan Amendment is intended to support up to 100 units,while the exact placement of housing units and open space areas will be further defined through the site process.

This plan also affirms the policy in the East Bay Regional Park District's Master Plan that a regional _ shoreline trail extending from Martinez to Point Pinole shall be implemented. The trails plan also shows a trail along Rodeo Creek from the southwestern edge of the planning area to the waterfront downtown. ^" 3 -93. The majority of open ace in this plan is located in the Franklin Canyon area and the adjacent hills.The J tY Pe space steep topography and unstable slopes which characterize the hills limit their fitness for development. Open space tions for this area reinforce the Countywide goal of agricultural preservation for continued Pace desi� agricultural productivity. The existing pattern in the open space area of relatively large parcels under consolidated ownership is necessary to successful range practices and will be maintained under this plan.The scenic value of the Franklin Canyon area has been asserted by the Rodeo community and is reflected in the -" scenic route designated for Highway 4 in the scenic routes section of the Transportation and Circulation Element.The hills and ridges along this route are the primary source of the corridor's visual quality and every effort should be made to protect its scenic characteristics. - —Because of noise related impacts, both from transportation sources and from industry, acoustical B P studies will be required for major new developments and multiple family projects in the Planning Area even those extending beyond the 60 CNEL Noise Contours. -- POLICIES FOR THE EL SOBRANTE AREA In cooperation with the Ci of Richmond, develop a Specific Plan for the San Pablo Dam Road - 3= p City . commercial corridor to provide detailed plans and implementation measures to increase parking for shoppers and increase roadway capacity for through traffic. 96.

For all industrial categories,the Plan should accommodate and guide the growth and development of industry. With growth and development there needs to be a recognition of environmental, social and economic values which will work to mixa* * e land use conflicts, to establish a reasonably pleasing setting and to protect natural resources that are irreplaceable. Through appropriate regulatory mechanisms (e.g., zoning ordinance,nuisance ordinance,etc.)provide for the following: 0 Require a setback from San Pablo and Wildcat Creeks for new structures. The size of the setback will be developed through site development review in conjunction with responsible agencies (e.g., Department of Fish and Game, Flood Control District). Lands within these setback areas shall reinforce the habitat values and/or trail setting of the adjacent flood control project for these creeks. o Require setbacks within shoreline areas to protect wetlands designated by State or Federal regulatory agencies and to provide public access as appropriate. The size of the setback or mitigation will be developed in conjunction with all affected agencies. 349 3.Land Use Element o Require health risks assessments and, where appropriate, provide necessary buffers for all new applications handling substantial amounts of hazardous materials. o Achieve an upgrading of the visual appearance and unity of the area through architectural and -- landscape requirements and utility undergrounding. o Require special geotechnical studies and construction techniques in areas of potential seismic or geological hazards (e.g., Alquist-Priolo Special Study Zone, high liquefaction, and reclaimed wetland areas). o Use established standards to limit activities that may endanger human health and can cause damage to the environment. o Use established standards to limit activities which may be objectionable such as odors, fumes or other emissions so they will be contained within the property boundaries. o Require projects adjacent to parks or recreational corridors to minimize impacts on the recreational values of those facilities. o Require a shadow analysis for projects adjacent to commercial nurseries and protect the solar access of affected properties. o Require archaeology reconnaissance surveys for all projects within an archaeological sensitivity area. When cultural resources are located within a project, measures to deal with the historic --� resource shall be recommended by a qualified archeologist. o Require all uses to comply with the regulations of the Bay Area Air Quality Management District,the Regional Water Quality Control Board, the San Francisco Bay Conservation and Development -- Commission,the State and County health departments,and any other regulatory agencies which exist or may be established to ensure environmental quality in the San Francisco Bay Region. o Screen all outside storage/maintenance areas from public streets. a .1.--- LIGHT INDUSTRY Amend the "Light Industry" land use category of the General Plan Land Use Element for North Richmond to read as follows: Industrial activities in this category are established in areas where development is carefully controlled to ensure compatibility between the industrial operations and other activities and the -- character of the district,community and environment in which they are located. The appearance of each site,building or industrial operation,and each industrial district as a whole,should establish a reasonably pleasing and harmonious setting. Types of uses within this category can range from research, engineering, product development and testing,and sales development to light manufacturing,warehousing,distribution centers,and commercial nurseries. Support retail/service uses may also be found in this category. In addition to the policies and factors established to guide development in all commercial and industrial areas, the following policies and factors are established to guide the development of Special Industrial areas: -- (1) "Apply special zoning designations or planned unit districts to provide use limitations,in cases where uses need to be limited to protect the character of an area,"in all cases where. (2) Limit activities which may result in noise, glare or vibrations extending beyond the property boundary." 5h HEAVY INDUSTRY snow Amend the "Heavy Industry" land use category of the County General Plan Land Use Element for North Richmond to read as follows: "Industry activities in this category are traditionally larger scale and include very little or no office -- space. Sufficient visual open space and/or landscaped screening between industrial operations and adjacent residential or recreational activities shall be required as needed." 3-50 3.Land Use Element This category accommodates a wide variety of activities including,but not limited to,oil refining, contractors'storage yards,warel"isess and sbops. For the North Richmond area,this category also nurseries. Support retail/service uses may also be found in this category. In addition to the policies and factors established to guide developtrient in all comms and irYdustrial areas,the following policies and factors are established to the development of General areas: 0 Encourage commercial nurseries to remain in the area. 0 Require projects involving auto dismantling activities to be enclosed and prohibit outside storage of vehicles. 0 Limit activities which may result in noise, clare or vibrations beyond the designated industrial areas. 0 Make a finding that new residential uses within this designation are incompatible. -3-174, —3T--22-10.

GROWTH MANAGEMENT PROGRAM 4.1 INTRODUCTION The purpose of this Element is to establish policies and standards for traffic levels of service and standards for fire, police,parks,sanitary facilities,water and flood control to ensure generally that public facilities consistent with adopted standards areprovided By including this Element in the adoption of the General Plan,the County intends to establish a long range program which will match the demand for public facilities to serve new development with plans,capital improvement prograrns and development impact mitigation programs. The intent is to ensure that growth takes place in a manner that will ensure protection of the health,safety and welfare of both existing and future residents of Contra Costa County. The responsible management of growth in the County is key to preserving the quality of life for current and future County residents. This Growth Management Element is the culmination of a process which was created by the Mayors'Conference and the County Board of Supervisors. The Contra Costa Transportation Partnership Cbmmission was established as a Transportation Authority under State law(PUC Section 180000)to provide a forum for transportation issues in the County and to propose ways to =em nage traffic congestion. 4:he r,,,�♦amis By a�rovfi Measure C-1988,the voters established�the Transportation Authority • law tA dal4alnm ga CnwatAXAA�4- gwnoAa�efl . , ` ' ' ' '- added one-half cent to the County sales tax for the next?U ,. , JL .

That pro<grain requires the Coim!y and each city to develop a Groyab Mauagemeiit Element as pait of its General. Plan in order to be eli Bible to receive local street maintenance and improvement funds oder-gene��lted b�• Measure C-.1988., - . This Growth Management Element complies with the model element developed by the Transportation Authority and includes the sections required by Measure C-1988 to be part of this Growth Management Element. These sections (1)adopt traffic levels of service standards(LOS)keyed to types of land use,and(2)adopt performance standards maintained through capital projects for fire, police, parks, sanitary facilities, water and flood control. The Transportation Authority fi.Ay "e rr~1 recognizes that facilities standards,as are discussed in this Element,establish performance standards to be applied in the County's development review process. In addition to adopting this Growth Management Element as part of the General Plan under Measure C-1988,the voters of the County,in Measure C-1990,reaffirmed that growth management should be an integral part of this General Plan. This Element is also adopted pursuant to the authority granted to local jurisdictions by Section 65303 of the Government Code of the State of California,which states: "The General Plan may include any other elements or address any other subjects which,in the judgement of the legislative body,relates to the physical development of the county or city." 4.2 RELATIONSHIP TO OTHER GENERAL PLAN ELEMENTS As indicated in Section 3,Land Use Element,the Growth Management Element works closely in conjunction with the Land Use Element to ensure that development proceeds in a manner which will not negatively affect facility and traffic service standards for existing land uses. In this regard,it should be noted that developments which cannot satisfythe requiredbythese standards should not be approved. By utilizing this Growth Management Element to responsibly manage new developmentthe County will ensure that new development projects will bear their share of the adverse burdens and impacts they impose on public facilities and servicers. As a result,the Growth Management Element must be carefully considered together with Land Use and other elements of this General Plan when assessing General Plan consistency. The timing of the potential physical development contemplated in the Land Use Element will in part be A ' ed by the ability of developers to satisfy the policies and standards 4-1 described in this Growth Management Element The Urban Limit Line(ULL)and the 65/35 Land Preservation Standard also work together with the Growth Management Element to ensure that growth occurs in a responsible n-mmer and sh*es balances between many con4xting values and interests. 41000, In addition, this Growth Management Element contains implementing programs which encourage new development to feeilitate the attainment e -promote the goals and objectives of the Conservation Element; the Public Facilities and Services Element;and the Housing Element. Moreover,by establishing an interjurisdictional land, supply and develgpment monitoring program, the Growth Management Element coordinates the WOO* implementation of the County General Plan with those of the 199 cities in the County. To carry out the goals and objectives of the Land Use and Circulation Elements of the Plan,new development must "Now demonstrate that the level of service standards of the Growth Management Element will be met Only in this way will the negative effects of such growth be avoided. While it is anticipated that new growth will be able to mitigate its potential facts through development fees and other exactions,it is possible that the timing of project approvals may be affected by the inability of individual developments to carry its appropriate cost of full service increments needed to allow further growth in a given area ofthe County. Thus,the improvements needed to implementthe CircWation and Public Facilities and Services Elements of the Plan will in part be directly tied to,and dependent upon,the implementation of the Growth Management Element. Similarly,implementation ofthe Land Use Element will only proceed when it can be dernonstraited,that the growth Noma* TrMM standards can be met by new development. Policies relating to this"Pay as you Grow"philosophy underpinning the Growth Management Element can be found in MON* the Transportation and Circulation Element,Overall Transportation/Circulation Goals 5-E and 5-F,and in the Overall Transportation/Circulation Policies 5-1 through 5-4. Related Land Use Element Goals 3-F and 3-H and Land Use Policies 3-5 through 3-10 are also part of the policy framework which underlies the Growth Management Element,and are integrally related to it. In a similar fashion, each of the required growth management performance standards included in this Element is also included in the Public Facilities and Services Element under the applicable goals and policies listed for sewers,water,police,fire,parks and flood control. 4.3 TRAFFIC SERVICE STANDARDS AND FACILITIES STANDARDS The basic unit ofmeasuziernent ofperfommnce ofan intersection or roadway segrnent is called a Level ofService(LOS).LOS is a measure ofthe ratio ofthe volume to capacity of a roadway or Mtersection and is as a letter A through F. In general LOS A describes fire flowing conditions,and F describes very congested conditions,with long delays. Routes of Regional Significance are those roadways which carry sivolutins of through traffic,which neither begins nor ends within the affected jurisdiction. They generally include Interstate Freeways and State Highways,as well as local roads which,due to their tow location between job and housing centers,carry signiflcant volumes of intra-county trips. All other roadways iii dffte pi are refeff ed to in the Growth Management Element as Basic Routes. &asic routes,and their sigr>i�li��rd intersections,are those to which LOS are applied in Imul6- proposed projects maybe 1 The methodology used in de imm if projects exceed allowable LOS standards is the 212 N&e.00111KOd 1AVidla 6esmediod established by the Contra.Cosw Tram pott-ifion Autliori!y fii its Technical Proceduits. At present,most Basic Routes in the unincorporated area operate at or better than the LOS Standards specified in the Growth Management Element. Tvlan3,Routes of Regional Significance are getais below these standards,however, reflecting the fact that the trips are not dependent upon land uses in unincorporated Contra Costa County,but are cumulative with traffic generated by land uses located outside ofthe unincorporated areas. Public Protection Facility standards contained in this plan are based upon the 1990 facilities to unincorporated population ratio. In the area of parks,for example,the current unincorporated population to park acreage yields a ratio of less than I acre per 1,000 persons. While certain developed areas of the County experience flooding in the event of the 100-year flood,the County Ordinance Code collect-and-convey requirements are applied to all new developments. Water and sewer services are generally adequate for existing development. low* For the purposes of establishing a Public Protection Facility standard,several factors must be considered. Firstly,the unincorporated community of Kensington has established a Community Services District which provides the full range of police services in the area,and the Sheriff does not service this area. Secondly,the California Highway Patrol is responsible for enforcement of the Vehicle Code on highways and County roads throughout the unincorporated area. Thirdly,certain economies of scale enable the Sheriffto provide patrol and investigation services in physical facilities 4-2 substantially smaller than a comparable series of cities would require,due to centralized administrative services,crime lab facilities and other similar functions which numerous cities would duplicate in each location. According to the Department,very little time is spent by deputies in the stations;nearly all is spent in the vehicles on patrol;no clericals are housed in the stations. In addition,the Sheriff also provides coroner services,incarceration and criminalistics services. For these reasons,direct comparisons between County facilities standards and standards that maybe adopted by cities in the County are not advised,since such comparisons would be highly misleading. The computation of a Sheriff facility standard in this General Plan includes only patrol and investigation services, adjusted for a marginal increase in centralized administrative services. As of January, 1991,the County provides approximately 155 square feet of floor area per thousand population in six locations throughout the County.—Iii 1997.it became evident that the Sherift"s Office needed to include support facilities necessary to conduct atrol. and lnyesti�ra�tio_.n.whicll are now included in the calculation of new square ..foo e. It should be noted that implementation of the goals of this Plan's various elements depends not only upon the County's administration of the Growth Management Program described below,but upon the interplay of several levels of government. Federal and State funding for improvements to Basic Routes will be required to attain and maintain traffic levels of service at designated levels. Finally,the County,the 1,9-9 cities,the Contra Costa Transportation Authority,the Bay Area Rapid Transit District,and the California Department of Transportation will all have to work cooperatively in order to mitigate the negative impacts of growth upon the regional transportation system to achieve the levels of population,housing and jobs anticipated by this Plan. 4.4 GOALS,POLICIES AND IMPLEMENTATION MEASURES GOALS 4-A. To provide for the levels of growth and development depicted in the Land Use Element,while preserving and extending the quality of life through the provision of public facilities and ensuring traffic levels of services necessary to protect the public health,safety and welfare. 4-B. To establish a cooperative inter urisdictional growth monitoring and decision making process in which each jurisdiction can share in the beneficial aspects of new growth,and avoid its potential negative effects. POLICIES 4-1. New development shall not be approved in unincorporated areas unless the applicant can provide the infrastructure which meets the traffic level of service and performance standards outlined in Policy 4-3,or a funding mechanism has been established which will provide the infrastructure to meet the standards or as is stated in other portions of this Growth Management Element. 4-2. If it cannot be demonstrated prior to project approval that levels of service will be met per Policy 4-1, development will be temporarily deferred until the standards can be met or assured. Projects which do not,or will not,meet the standards shall be scheduled for hearing before the appropriate hearing body with a staff recommendation for denial,on the grounds that the project is inconsistent with the goals,policies, and objectives of the Growth Management Element of the County General Plan. 4-3. Table 4-1 shows the performance standards which shall apply to development projects. In the event that a signalized intersection on a Basic Route exceeds the applicable level of service standard,the County may approve projects if the County can establish appropriate mitigation measures,or determine that the intersection or portion of roadway is subject to a finding of special circumstances,or is a Route of Regional Significance, consistent with those findings and/or action plans adopted by the Contra Costa Transportation Authority pursuant to Measure C-1988. Mitigation measures specified in the action plans shall be applied to all projects which would create significant impacts on such regional routes,as defined by the Authority in consultation with local agencies and as permitted by law. For the purpose of reporting to the Contra Costa Transportation Authority in compliance with the Growth Management Program,a list of intersections that will be reported on Basic Routes will be prepared and maintained by the Community Development Department. 4-3 4-4. The County institute an ongoing growth management program process,as generally depicted in Figure 4-1. *.low 4-5. For the purpose of applying the Traffic Level of Service standards consistent with Measure C--1988 only, unincorporated areas subject to the growth xnanagejnent standards of this Element shall be characterized as Central Business District Urban,Suburban,Semi-rural and Rural as depicted in Figure 4-2. Pow% 4-6. Conformity with the growth management standards will be analyzed for all development projects such as, subdivision maps,or land use permits. A general plan amendment is a long range planning tool and is not to be considered a development project or a project approval under the growth management program. Traffic LOS Standards will be considered to be met if: 0 measurement of actual conditions at the intersection indicates that operations are equivalent to or better than those specified in the standard;or 0 the County has included projects in its adopted capital improvements program which, when own* constructed,will result in operations equal to or better than the standard. TABLE 4-1 GROWTH MANAGEMENT PERFORMANCE STANDARDS Traffic Levels of Service Keyed to Land Use Type Rural Areas: Peak Hour Level of Service of low C (Volume/Capacity Ratio=.70-.74) Semi-Rural Areas: Peak Hour Level of Service of high C (Volume/Capacity Ratio=.74-.79) Suburban Areas: Peak Hour Level of Service of low D (Volume/Capacity Ratio=.80-.84) Urban Areas: Peak Hour Level of Service of high D (Volume/Capacity Ratio=.85-.89) Central Business Peak Hour Level of Service of low E Districts(CBD): (Volume/Capacity Ratio=.90-.94) Note: These terms are used solely with reference to the Growth Management Element performance standards. Water The County,pursuant to its police power and as the proper governmental entity responsible for directly regulating land use density or intensity,property development and the subdivision of property within the unincorporated areas of the County, shall require new development to demonstrate that adequate water quantity and quality can be provided. At the project approval stage,(subdivision map,land use permit,etc.),the County may consult with the appropriate water agency. The County,based on information furnished or available to it from consultations with the appropriate water agency,the applicant or other sources,should determine whether(1)capacity exists within the water system if a development project is built within a set period of time,or(2)capacity will be provided by a ftmded program or other mechanism. Project approvals conditioned on(1)or(2)above,will lapse according to their terms if not satisfied by verification that capacity exists to serve the specific project("will serve letters"), actual hook-ups or comparable evidence of adequate water quantity and quality availability. 4-4 moo i 1 ■ •O Lm cc LO >, L Low LO 0 — N O o V _ �-, 0 C 0 as cc _ 4� •i = _° ` m � •� � aLD o0 '� c� Ida Co CM 0 0 0 _ _O _ _ _ V = �• V. 0 •_ O .� _ 0._ = o *a w v a 0 E c i ` >% O Cc !Q cc 0 0 0. a d- .0 C — a. cccis ca m L L L A o c� o a Page 0 Two0 0 � � � w 4-5 l J t ' is ,r i i ENO Pon lob Y a f-" sit, r K .•' 1 1 -•+ �� tf x tii�• '+1�'s t1-6.r'■«'t' f�i U3 #• ,L'`1` {:},•t . x�i3+y l D t as L y iz t•a'x,14}i,isi,r;'�Rwt'!1t 1 i i.•t4 t ;inning wig s K� E ! •" 1•. •. !.1:•`.i.. •.•. 11.■.•'t..• � M 1/11•Rfw •k • t"•ii t t1 11� {'. r•_• �- jf Y$ Q'a' 2 r Fr J ►�,r wt 't•'� •t' +' `'+�' 1.•`«'■ �' .RG r7 ow" 'r }K Q i T' ,}•t' ;1• ,t tt"i t f {{ ,1.. s a)'► '" •�eqw iri r••t•t �. ,...t,i r FIs. ��`.-•�4 a/i�•w}tr a m.

At the project approval stage,(subdivision map,land use permit,etc.),the County may consult with the appropriate sewer agency. The County,based on information furnished or available to it from consultations with the appropriate sewer agency,the applicant or other sources,should determine whether(1)capacity exists within the sewer system if the development project is built within a set period of time,or(2)capacity will be provided by a funded program or other mechanism. Project approvals conditioned on(1)or(2)above,will lapse according to their terms if not satisfied by verification that capacity exists to serve the specific project("will serve letters"),actual hook- ups or comparable evidence of adequate sewage collection and wastewater treatment capacity availability. Fire Protection Fire stations shall be located within one and one-half miles of developments in urban, suburban and central business district areas. Automatic fire sprinkler systems may be used to satisfy this standard. Public Protection A Sheriff facility standard of 155 square feet of station area and support facilities per 1,000 population shall be maintained within the unincorporated area of the County. Parks and Recreation Neighborhood parks: 3 acres required per 1,000 population. Flood Control and Drainage Require major new development to finance the full costs of drainage improvements necessary to accommodate peak flows due to the project. Limit development within the 100 year flood plain until a flood management plan has been adopted and implementation is assured. For mainland areas along rivers and bays, it must be demonstrated that adequate protection exists through levee protection or change of elevation prior to development. Development shall not be allowed in flood prone areas designated by the Federal Emergency Management Agency until a risk assessment and other technical studies have been performed. IMPLEMENTATION MEASURES 4-a. Incorporate the performance standards outlined in Policy 4-3 into the review of development projects. 4-b. Work cooperatively with the 1,99 cities and the Contra CostaW n�Transportation Authority through each of the SubRegional Transportation P.lau1Committees to define action plans for mitigating the impacts of development on Routes of Regional Significance. 4-c. Require traffic impact analysis for any project which is estimated to generate 100 or more AM or PM peak-hour trips based upon the trip generation rates as presented in the Institute of Traffic Engineers(ITE) Trip Generation,+6th edition, 19 97,o.r the.most cinTent published edition. 4-d. Require that during the review of development proposals, the traffic impact analysis shall determine whether a project could cause a signalized intersection or freeway ramp to exceed the applicable standard and shall identify mitigations/fees such that the intersection or ramp will operate in conformance with applicable standards. Development proposals shall be required to comply with conditions of approval detailing identified mitigation measures and/or fees. In no event shall Local Road Improvement and Maintenance Funds replace development mitigation fee requirements,pursuant to Measure C-88. 4-7 •....,, 4-e. Establish through application to the Contra Costa Transportation Authority,and in conjunction with the regional committees,a list of Routes of Regional Significance and Intersections proposed for Findings of Special Circumstances.

Adoption of Performance Standards The first step in the growth management program process is completed upon the adoption ofe standards for public facilities and services in this Growth agement Elerrient. Figure 4-1 shows the flow chart ofthe growthmanageme 1 process. Land Sumly/Development Monitoring Analysis The second step in the growth management process,an analysis of land supply and development monitoring,will con m=ce at the beginning of each calendar year. Annual status reports on the implementation of the General Plan and its Growth Management pfogmmElenient will be submitted to the Board of Supervisors and City Councils in June. This status report will fulfill the requirements ofGovernnmt Code 65400(b)in the State planning and zoning laws,which requires that every " city and county must prepare an annual report to the City Council or Board of Supervisors and the State which summarizes the status of the General Plan and the progress that has been made in its implementation.The subsequent steps in the process, commencing with the perf�ce standards evaluation,will occur on a five-year cycle. The land supply and development monitoring process is a two-part component designed as the basis for the periodic re-examination of lands available in the County for urban development. The availability of developable lands is then contrasted against the actual rate of growth which has been measured over the most recent period. In essence,this component is a land supply and demand tracking process. This process is designed to work in tandem with the other four components (performance standards/infrastructure constraints analysis, inter urisdictional coordination, jobs/housing balance analysis, and growth management determinations) in order to obtain an updated,working perspective of the current capacity of the County to accommodate growth. The land supply 1 and development monitoring process is prepared in an objective fashion by staff, using a set mo" methodologydefined and agreed to by the jurisdictions involved(the County,the 1,99 cities,the Local Agency , gr Formation Commission(LAFCO)and the individual service providers). The re-examination of the land supply (initially set by the General Plan Review Program) will occur on an annual basis, in concert with the State -� Population Certification program which is already conducted l.?Y.J�,1 the County and each city planning department. . ' '. a .. eal ndnr .c r.r• Using a standard format and methodology should provide a high degree of confidence in the process and the established annual schedule should alert the development interests,city agencies,and special districts as to when their contribution will be critical. At the beginning of each annual cycle,formal notification will be given to each of the cities informing them that the land supply and development monitoring process is being initiated and requesting their active participation and cooperation. 4-12 "x' 63 X C—fiql wk X Au 4 aiu--ulm 41'-AI:14 The Land Use Information System(LUIS),developed in 1987,%�-.Y 'W-'%..-"I A. 1,"a&1-6'%.'A,1..V F.&%"4 AAAJ MAZAA AWA amaiid the more recent Geo c Inf ste provides the foundation for tracking Geaei.A- Plan RR-Nieyv..A%.fb ormation Sy * overall land supply,land absorption,and changing land uses in the County. The specific questions that must be answered during this process with the use of the updated LUIS data system are: 0 how many acres of vacant land in the County,specified by land use type,are identified as available for development.? 0 what changes have occurred in these numbers since the previous evaluation? 0 how many acres of underutilized or previously developed land are available for redevelopment? 0 how many acres of land County-wide have been identified as unavailable for development based upon environmental,health and safety,public resource,or other conditions?The County Community Development Department staffwill prepare a report which examines the absorption rate(i.e.approved development projects) and the General Plan Amendment requests that have been received. The report on the status of development areas will rely upon residential and commercial/industrial building permit and other project approval information from the cities. This permit approval and General Plan Amendment application information will then be compared to the expected rate of residential and job growth projected for the jurisdiction over the planning period by the respective General Plans. The annual report will be forwarded to decision-making bodies for use in reviewing fin-ther General Plan Amendments which would alter the land supply component. Performance Standards Evaluation and Infrastructure Constraints Analysis While the second component of the growth program(land supply and development monitoring)will be prepared on an annual basis,the final four components will generally be performed only once every five years. Although these final four components of the Growth Management Program will be comprehensively and formally evaluated every five years,circumstances may necessitate evaluating and modifying the standards during the annual review of the land supply and development component of this Growth Management Program. If circumstances so necessitate,the Board of Supervisors should consider all information before it including the Land Supply/Development Monitoring Analysis,fiscal constraints,and other information obtained through consultation with the s0llt 43L 3&1&ty-Contm Costa Transportation Authority, before modifying the standards. The data and analysis generated in the annual land supply and development monitoring reports will be aggregated for use in the tasks outlined in the following processes. The intent of this third component of the growth management program,performance and infrastructure capacity evaluation,is to re-examine minimum allowable performance standards for development projects set in the General Plan, and to determine the remaining available capacities of certain infi-astructure facilities. The growth management program for the Contra Costa County General Plan mandates the establishment of infrastructure performance standards for several different services or facilities, including circulation (traffic), sanitary sewage,flood control and drainage,water supply,police and fire protection and emergency services,and parks and recreation. These standards and policies attempt to define a quality of life by setting benchmark indicators of the minimum levels of service required for specific urban services. Every five years the- e standards would be reviewed by staff and the service providers by e�ining prior experience and ability to serve. In addition,service districts may be provided an opportunity to explain why certain standards are not being met and to explore measures to be taken to alleviate the situation. This information would then be used to evaluate whether the standards for the current review period were appropriate. The second major task to be completed during this phase of the growth management program is an evaluation of the remaining infrastructure capacity in various areas of the County. Part of this evaluation will determine where and why certain existing urbanized areas are not being adequately served. The assumption is that adequate infrastructure capacities can be engineered and built to serve virtually any amount and location of urban growth within the ULL,but that opportunities exist to plan for cost-effective and efficient growth in areas particularly within the ULL,where underutilized infrastructure capacities already exist or where the extension of services is relatively unconstrained compared to other areas. 4-13 The basic data requirements of this portion of the process include: 0 a determination of the remaining capacity for each facility or service provider based upon the defined performance standards,and identification of the geographic areas that could be served by the capacity; 0 an itemization of funded infrastructure improvement projects, their location and expected date of completion,and the service area or population they are designed to serve; 0 identification of urbanized areas with inadequate service,as defined by the adopted performance standards; 0 an itemization of the major capital improvements not now funded but needed to bring existing areas into compliance with the performance standards; 0 itemization of major capital improvements necessary to serve anticipated future development at the adopted service level,and the cost of these improvements; 0 identification of major physical,economic and/or environmental constraints to the provision of service or facilities in a given area;and 0 identification of possible sources of funding for the improvements. The object of the data gathering is to illustrate where future growth can and cannot occur without major investment n new or improved infrastructure systems,and to identify the level and source of financing required. Additionally, the exercise will allow the preparation of estimates of future required capacity based upon the performance standards. One outcome of this process will be to provide with up-to-date *information concerning where future Soaft growth is expected to occur,thus assisting in capital facilities planning efforts. To ensure that high density"leapfrog!'growth does not occur,as a matter of policy,this growth management program **Now mandates that new urban and central business district levels of development shall not be approved unless the development is within the ULL and near existing or committed urban or central business district levels of development. Jobs/Housine Performance Evaluation The purpose of this step is to provide a basis for assessing the jobs/housing balance within each section of the County for the current five year review cycle,to assist the jurisdictions in the sub-regions in determining preferred locations for residential and employment growth,and to assist in focusing the direction of implementation programs. The jobsthousing balance evaluation is based upon the County's Land Use Information System data base,augmented by the infon-nation provided in the development monitoring evaluation. The evaluation considers growth in housing units and employment and housing and employment availability,relative affordability and commute patterns,and to the extent that the data are available,price of the units and wage levels of the jobs added. The jobs/housing performance evaluation will be used to identify areas where jobs or housing should be stimulated and encouraged. It would also be used to provide information about areas in which infrastructure deficiencies need to be corrected in order to facilitate a better jobs/housing balance. Interjurisdictional Coordination and Decision-Making The growth management program outlined here will not succeed without the cooperation and active participation of the County,the Local Agency Formation Commission,the 189 cities,and the service providers. These agencies and cities may view cooperation with the Count's nanagement program as a threat to their local authority over land use or other growth issues. The County's efforts to achieve cooperation must be aimed at persuading the cities and agencies that the growth management program will ultimately enhance their ability to meet their own General Plan goals. In addition, the County will participate in the cooperative planning process established by the (2gunpi vlr% 1%_11%.X%"&%T Iransportation .AuthoritvG.e.ff.wnt*,%.i...n:,:1 for the purpose of reducing the cumulative regional traffic impacts of development. *Now 4-14 Inter urisdictional cooperation would not require all of the cities and agencies to adopt the same goals,policies and implementation measures as will be 'included in the County's General Plan and growth management program. However, it would be desirable for the County to request that the cities and agencies adopt resolutions that specifically recognize and accept the growth management program and its premise. A key commitment by the jurisdictions involves the dedication of a relatively small,but adequate,level of staff time to assist the County in gathering the required data for the necessary planning studies. Additional commitments must be made on the part of policy makers and staff to review the annual land supply and development monitoring reports, consider them when making important planning decisions, and to actively participate in the growth management determination process every five years. Growth Management Determinations Building upon the preceding components of the growth management program, the final aspect of the process involves using the reports that have been generated to make the important decisions about where future growth in the County should be encouraged in order to minimize infrastructure costs and to enhance the overall level of "quality of life." The process for making these determinations is as important as the determinations themselves. The process can help to achieve consensus among cities and the County(in consultation with service providers)as to appropriate amounts and locations of new residential,commercial and industrial growth in the County. The growth management determination process should include the following steps,several of which are based upon information developed in the previous components of the program: 0 indicate on a County General Plan map the current city boundary lines,Spheres of Influence,the Urban Limit Line and current service areas for all of the major utilities/facilities; 0 add to the base map information regarding improvements or extensions to service systems that have been completed since the last review period or improvements itemized in capital improvement programs,as well as constructed and approved development projects and adopted General Plan Amendments; 0 identify lands that have been determined to be undevelopable; 0 identify on the map the geographic areas with infrastructure constraints and the locations of development projects that have been unable to meet performance standards; 0 review the annual land supply and development monitoring reports in conjunction with the performance standards and infrastructure constraints analysis reports to determine whether an adequate supply of vacant land is designated for urban use in the County and city General Plans,on both a Countywide and subregional basis, to allow the anticipated amount of urban development during the remainder of the twenty year period. This urban development must be subject to the 65/35 Land Preservation Standard. (See Section 3,Land Use Element.) 0 Determine whether adjustment to the urban limit line is needed in order to provide sufficient land to accommodate anticipated needs. Growth management determinations shall be made in consultation with the Goun. Trmisportation Authority. In it is anticipated that these growth - determinations, will be made in a series of joint meetings conducted on a subregional basis with representatives of the cities. The Local Agency Formation Commission(LAFCO)and the service districts should also be consulted. Staffwill present the base map and accompanying reports to the County and City Pbnning Commissions,LAFCO and service district boards,with a request that the agencies review the recommendations and make formal comments. After this review period is complete and appropriate changes,if needed,have been made,the map and reports will be recirculated to all of the jurisdictions in the County. The final action will be to request that the cities,LAFCO and service providers adopt resolutions in support of the recommendations and to initiate any General Plan Amendment hearings which may result from the review process. 4-15 Definitions of Terms The following definitions apply to the geographic terms used with respect to the Growth Management Element pregram only. The level of service designations for unincorporated County areas are shown in Figure 4-2. R,=. Rural areas are defined as generally those parts of the County that are designated in the General Plan for agricultural,open space or very low density residential uses,and which are characterized by medium to very large parcel sizes(10 acres to several thousand acres). These areas have very low population densities,usually no more MOM than 1 person per acre or 500 people per square mile. Suburban. Suburban areas are defined as generally those parts of the County that are designated in the General Plan for low and medium density single family homes; low density multiple family residences; low density meow neighborhood- and community-oriented commercial/industrial uses; and other accompanying uses. Individual structures in suburban areas are generally less than 3 stories in height and residential lots vary from about one fifth of an acre(8,000 or 9,000 square feet)up to 2 or 3 acres. Population densities in suburban areas fall within a wide ...ft range,from about 1,000 to 7,500 persons per square mile(1.5 to 12.0 people per acre). Urban. Urban areas are defiled as generally those parts of the County that are designated in the General Plan primarily INNNO for multiple family housing,with smaller areas designated for high density single family homes;low to moderate density commercial/industrial uses; and many other accompanying uses. Urban areas usually include clusters of residential buildings(apartments and condominiums)up to three or four stories in height and single family homes on relatively small lots. Many commercial strips along major arterial road are considered urban areas. 104 Examples of urban areas in Contra Costa County are the older neighborhoods in Richmond,El Cerrito,Pittsburg, and Antioch and the downtown commercial districts in smaller cities such as Martinez,Danville,and Lafayette. -- Population densities in urban areas are usually at least 7,500 persons per square mile (12.0 people per acre). Employment densities in commercial areas may range up to about 15 jobs per acre. Central Business District/Maior Commercial Center. Central business districts or major commercial centers are defined as those areas designated in the General Plan for high density commercial and residential uses. They consist of either the downtown area of a major city in Contra Costa County (Concord, Walnut Creek, and Richmond)or a large business/office complex(such as Bishop Ranch or the Pleasant Hill BART station area). AMMOO These areas are characterized by large concentrations of jobs and consist of clusters of buildings four stories or more in height. CBD's or major commercial centers generally have employment densities. mum N~ Now 4-16 `� 5.

TRANSPORTATION AND CIRCULATION ELEMENT 5.1 INTRODUCTION The purpose of this Element of the Contra Costa County General Plan is to establish transportation goals and policies, and to establish specific implementation measures to assure that the transportation system of the County will have adequate capacity to serve planned growth in Contra Costa County through the year 20209.The intention of this Element is to provide a plan and implementing measures for an integrated,multi-modal transportation system that will safely and efficiently meet the transportation needs of all economic and social segments of the County and provide for the transport of goods and services throughout Contra Costa County. The transportation system outlined in this Element recognizes on the one hand the limited availability of transportation funding and,on the other hand,increased demands for mobility within Contra Costa County. As a result,the Element emphasizes the efficient use of the existing transportation system,particularly existing roadways and transit systems,and cost effective enhancements to this system to accommodate planned growth consistent with the Land Use Element. Nonetheless,the County will continue to seek revenue from a variety of sources for needed transportation improvements and to work toward the establishment of new and creative funding mechanisms(i.e.,private/public and regional partnerships)consistent with the goals and policies of the Growth Management Element and Measure C- 1988. LEGAL AUTHORITY The Transportation and Circulation Element is prepared pursuant to Section 65302(b) of the California Government Code. This Element has been a mandatory component of local General Plans since 1955. The Transportation and Circulation Element is required to address the location and extent of existing and planned transportation routes, terminals, and other local public utilities and facilities. It is further required to be consistent with the other elements of the General Plan,accommodating future travel demand and contributing to,rather than inhibiting,the attainment of desired land use patterns in the Land Use Element. 5.2 RELATIONSHIP TO OTHER ELEMENTS Section 65300.5 of the California Government Code requires that the various elements of a General Plan comprise an integrated, internally consistent,and compatible statement of policies for the adopting agency. The law emphasizes that the Transportation and Circulation Element be coordinated with the Land Use Element. The transportation plan,policies,and implementing measures established by this Element comply with the requirement by utilizing the same projections of future population and economic activity as does the Land Use Element,by using the same geographic distribution of future population and economic activity as expressed in the Land Use Element map,and by designing the transportation plans and policies to contribute to the achievement of the planned land-use pattern. The Roadway and Transit Network Plans shown in this element have been constrained to reflect limited financial resources. Consistency with the Land Use Element is maintained through the interplay of these elements with the Growth Management Element. The Transportation and Circulation Element funding programs�e�e�-�tefor capital projects are correlated with the programs contemplated in the Growth Management Element. The Transportation and Circulation Element incorporates the implementation of the Contra Costa Transportation Authority's (CCTA), Expenditure Plan passed by the voters in November 1988. This Element also assumes availability of the revenue generated by Regional Measure 1,the Propositions 108, 111 and 116 approved by the 5-1 5.Transportation and Circulation Element Mow voters in June 1990,the California T'raffic Congestion Relief Act of 2000,and Proposition 42 approved by the voters m 2002. This element also asstunes maintenance of the various fee programs on new development established by the Cogn ,to constma the road facilities needed to seltiJe that development. The Board of Supervisors designated the CCTA as the Congestion Management Agency for Contra Costa County. The County -meets the congestion management planning requirements through the planning process established by the CCTA. A separate Scenic Routes Element was previously required as a mandatory General Plan component. However,state law now encourages the scenic routes'goals and policies be included within the Transportation and Circulation Element. Thus,this plan merges the scenic route discussion and policies into this Element. Biking,Hiking and Equestrian Trails Plans are included as part of the Recreation section of the Ptib.:'ke . N.-Open Space --- Element. It should be noted that some transportation related issues are included in other elements of the Contra Costa County General Plan. Policies that address the impacts of vehicle emissions on air quality,-#. +Me:are found in the Open Space/Conservation Element. The Noise Element also addresses transportation issues by identifying the .�.. noise impacts of traffic in the County,based upon the Roadway Network Plan and the traffic volumes that are forecasted on key roadways. The topic of oil and natural gas pipelines,often covered in Circulation Elements is discussed in the Safety Element. moon 5.3 RELATIONSHIP TO OTHER GENERAL PLAN DOCUMENTS The goals,policies and implementation measures contained in this Element are intended to guide planning for public and private projects that are subject to either approval of the County planning agency,or to review by County staff, although they may be under the jurisdiction of other public agencies operating in the County. Such goals,policies and implementation measures are further intended to be in accordance with other elements mom of the General Plan, as well as with other planning documents, such as the Contra Costa Transportation Autho it„y's Count3Afide C�'alnprehensive Transportation Plan '• The Transportation and Circulation Element is largely consistent with the Metropolitan Transportation Commission's -1-988-2001.Update of the Bay Area Regional Transportation Plan. The:EL�ist County Corridor and the 1-680 b swa�► through the State Route 24 interchange ...* .. . ,are not included in the Regional Transportation Plan. 5.4 ORGANIZATION OF TRANSPORTATION AND CIRCULATION ELEMENT This Transportation and Circulation Element addresses roadways,transit,bikeways,and transportation demand management(TDSM)programs,as well as air,rail,and water transportation facilities. The format of the Element is as follows: 1.M An analysis of existing and future transportation needs, e0m ed A,A IL N7 . . . 2. The fundamental concept that shapes this element. 3.{33 A presentation of �' ' ' . , goals, policies and implementation programs for each of the following topics: o Roadways and transit o Transportation System Management o Bikeways o Scenic Routes o Airports and Heliports o Ports and Proprietary Wharves 5-2 " 5.Transportation and Circulation Element o Railroads Note that the required discussion of terminals is provided as part of the treatment of airports,heliports,ports, proprietary wharves,and railroads. 5.5 EXISTING AND FUTURE TRANSPORTATION NEEDS Travel conditions in Contra Costa County are greatly influenced by its location on the eastern side of the San Francisco Bay metropolitan region(see Figure 5-1). Bridges,freeways,and trains link Contra Costa to every part of the Bay Area. Commute patterns are especially affected by the employment centers in San Francisco and Alameda County,and the residential areas of Solano County. Itis esri.rx�ated ttlat ? .. • nf.n I I • and 46 percent of work trips originating in Contra Costa are destined for another Bay Area county. Such inter-county travel patterns require that the Transportation and Circulation Element recognize the impacts � p of development outside Contra Costa County in addition to projected development inside the County. The Element accomplishes this task by incorporating projections of future population and employment activity in the remaining eight Bay Area counties for the year 2020-5. These projections were prepared by the Association -- f of Bay Area Governments,and were combined with the Contra Costa data to estimate the influence of regional growth on the level and orientation of travel in the County. Estimates of inter-regional traffic,primarily from the Central Valley,were also included in the forecasts. EXISTING NETWORK The County's transportation system is comprised of an;R"E ,• �r „.,n •� � *•d network of Federal, State and County roads, regional transit systems, bikeways, elderly and <1transportation services (paratransit),as well as air,water and rail service,and pipelines. Pipelines are discussed in the Safety Element. Roadways The County's roadway network includes Interstates 80,580,and 680,State Routes 4,24 and 242, ...Sta4e Route . In addition,numerous locally maintained arterials,streets and roads makeup the remaining network. Of special importance are the four bridges and three tunnels that link Contra Costa with the Bay Area Region. These include the Richmond-San Rafael Bridge,Carquinez Bridge,Benicia-Martinez Bridge,Antioch Bridge,and the Caldecott Tunnel. 5-3 Figure S-1 East Bay Regional Highway and Transit System ' , Sacramento Dixon Naps Yolo y Cou buy Pot x�.

Bus Bus service makes up the balance of the County's mass transit system. AC Transit serves portions of Western Contra Costa County with fixed bus service to Northern Alameda County and downtown San Francisco. The northwest portion of the County is served by the Western Contra Costa Transit Authority(WESTCAT),which operates both fixed-route and demand-response dial-a-ride buses. Central Contra Costa County is served by both fixed route and demand response buses operated by the Central Contra Costa Transit Authority(CCCTA),also called the County Connection. The eastern end of the County is provided both fixed route and demand-response bus service by the Eastern Contra Costa Transit Authority(Tri-Delta). Park and Ride Park and Ride facilities have been established throughout the County to encourage the use of transit and high occupancy vehicles. BART maintains twelve park and ride lots In Contra Costa providing over-1-I Ran 18,1)00 parking spaces forPALA 'BART .. - atron. s. Ten of these.lots are at BART stations and others are in Antioch and Brentwoodat • = • . Caltrans has established t# =teen-sixteen park and ride facilities in the County providing over€60 1.,600 spaces ,which are used primarily as staging areas for carpools and vanpools. ���H��.ILt wiciely 1 Bikeways County bikeways include both on-road and off-road facilities which are operated and maintained by the County,cities and the East Bay Regional Park District. According to a 2001 MTC Surygy for the nine-county Bay Area,bicycles account for 1.4 percent of all trips .. ,8 5 percent of . rthese trips are trips towyork. However,bikeways in the County are currently dominated by recreational users and are not widely used for commute purposes. The Counter is currently partigipatin,=in a countywide effort sponsored by CCTA to evaluate ..': ores ways of increasing the use of bicycles.for A. transportation-. Further discussion,as well as goals,policies and implementation measures,regarding bikeways are included in the "Parks and Recreation"section of the�i�iz -Open Space� Element. AMTRAK AMTRAK operates both long distance and intercity trains throw Contra Costa County. Intercity senrice is in.e.r.easing, 11. trains operate daily between Sacramento and Oakland thru Contra Costa 8 trains operate daily between Oakland and Bakersfield through Contra Costa County. ' , .. 5-5 5.Transportation and Circulation Element Air,Water and Railroads Several air,water,and railroad transportation systems and facilities are located within the County. A description and policies regarding Buchanan Field and the East County airports is found in the"Airports and Heliports"section. A similar description and relevant policies for water transportation facilities are included in the section "Ports and Proprietary Wharves",and rail-related facilities and policies are described in the"Railroads"section. EXISTING TRAVEL DEMAND The most comprehensive and recent data on local travel was collected from two sources,dttthe -- Metropolitan.Transportation Commission's(MTC)2.001 Regional Transportation Plan and the?000 Census Journ.ev to Work data.The.R.e zional Transportation Plan released by MTC;in 2001 rives a wene-ral over<=iew of reizional and local travel patterns within Contra Costa and the Bay Area. In addition the plan forecasts future .. travel demand,whicll is discussed in Ln-eater detail in following section.The 2000 Census data documents the travel data of 3,416,710 Bay=Area commuters and provides the most succinct oven4ew of where Contra Costa and Bay .Area Residents live and work. It should be noted that at the time of this revision staff from MTC;are evaluating how the.2000 Journey to Work Census Data,released in March of 2003 effects the data presented in the 2001 Re hona.l Transportation Plan as this plan was prepared prior-to the data released by the U.S.Census Bureau. 1 ' r • %.. . mom The.Metropolitan.Transportation Commission estimated that Contra Costa County residents made an average of 2 million vehicle trips in 2000, per day.

FUNDAMENTAL CONCEPTS THAT SHAPE THIS ELEMENT The projected increase in travel demand will require expanded transportation facilities and services, since existing facilities are strained to near capacity in one or bath directions during rush hours. The need to provide g1a a -expanded facilities poses both environmental and financial problems. The Transportation and Circulation Element can be used to guide, shape and control growth itself and should therefore relate to the issue of growth. However, it is only one component of a General Plan designed as a development, conservation and economic blueprint for the County. Roadway and transit improvements do not necessarily lead to uncontrolled growth. The Land Use Element and Growth Management Element set the timing and densities of future growth. A well-planned and balanced transportation network provides for and accommodates anticipated employment and residential growth and helps to relieve existing congested roadways. A defined transportation network also gives public and private interests a vision of needed improvements and an opportunity to assess costs and develop funding programs well in advance of actual growth. -- The following fundamental concepts have been recognized in developing this Transportation and Circulation Element: o Traffic flow is limited by the capacity of the system. o There are formidable limits to expansion and/or improvements to the system. o A desirable living environment and a prosperous business environment cannot be maintained if traffic levels continue to increase without limits. Various methods must be used to control and reshape the impact of automobiles in Contra Costa County and to "` � xtprovide convenient and reliable alternatives to commutintr alone by car. o When traffic demand sinificantly exceeds the capacity of the system, many negative effects can 5-8 5.Transportation and Circulation Element festuccur,including congestion,loss of time and productivity,accidents,personal frustration,increase in pollution,adverse community reaction;and use of residential streets for commuting purposes. o Contra Costa County,the Bay Area and California will continue to experience population growth over the next 20 years and transportation systems will continue to be strained. o Near-term solutions to conflicts between traffic demands and system capacity limits require utilizing existing roadways to the effective limits of their design capacity in order to rte-manage congestion. o Longer-term solutions require either significant enhancements to the system,fundamental changes in travel behavior patterns,or a combination of both. • Some of the specific approaches proposed in this Element for both near-term and longer-term solutions include the following: Place limits on the capacity of streets and highways which enter the County(near-term). — t rr&,,f ility,md gm nietxe of'irxand' ttwx itservice(bW4=4 — Expand undersized roadways and plan for new roadways(longer-term). Accept congestion untilrax-©rr,�...t;. E ""aS an in��1=itabl�� traffic condition dtrt-ing rush hours(near-term). �� — Improve the design of new development to provide alternative routes for circulation on the roadway system(near-and longer-term). Improve the design of new development to allow convenient aeeess t{ause of alternative forms of transportation. — Encourage ride sharing and staggered work hour programs(near-term). Construct HOV lanes and on-amp metering lights along commute corridors(near-term). o Even with the investment of$348.6 billion in State and Federal revenue to add to local funds for transportation improvements over the life of this plan, the amount of growth in the region and the attractiveness of travel by private automobile will make desired level of service standards (LOS) unattainable along portions of County roadways. 5.6 ROADWAYS AND TRANSIT INTRODUCTION The need for roadway and transit facilities is most directly tied to the land use patterns set forth in the Land Use Element. As described above,buildout of the land use plan through the year 20052020,together with anticipated growth outside of the County,would place excessive demands on the existing circulation infrastructure in the County. The goals,policies and implementation measures set forth in this section,together with those in the Growth Management Element,are intended to address the future circulation needs of Contra Costa County. ROADWAY AND TRANSIT NETWORK PLANS The Roadway and Transit Network Plans are the result of a coordinated planning process that incorporates the goals, policies and implementation measures of this Transportation and Circulation Element,in addition to the Land Use Element and Growth Management Element. As such,these network plans are a compromise between the ultimate 5-9 5.Transportation and Circulation Element transportation needs of the County,fiscal reality,and the potential development constraints imposed by the Growth Management Element. The premise of the Roadway and Transit Network Plans is therefore best sununarized as follows: o A roadway and transit network plan to accommodate travel demand that would result from assumed year?88-5-2020 buildout of the land use plan was developed. Fall ., . liam There is a shortfall in luldinl,to implement this plan. 9- A , , • r .. , ♦ ►. nc duan ./ o The combination of the 2 -Land Use plan with a Ffmancially Ggonstrained transportation network,and the provision of the Growth Management Element,will have the effect of slowing growth in the County until additional transportation revenues are secured and more efficient commuting habits are adopted.

ROADWAY DESIGNATIONS AND DESIGN CRITERIA This section describes the classifications of roadways shown in the accompanying Roadway Network Plan. The purpose of the classifications is to define the Circulation Element's intent for the function and design of roadways specified in the Roadway Network Plan. Freeways womb Freeways are defined as controlled-access, high speed roadways designed to cavy high volumes of intercity, intercounty,and interstate traffic,although they may carry considerable local traffic in urban areas. This class of facilities is devoted entirely to the task of traffic movement, and performs no direct land service function. The onnap following design standards shall apply to freeways: 1. Opposing travel lanes shall be separated by a median. --- 2. Access shall not be permitted from abutting parcels. 3. Auxiliary lanes may be provided from one interchange to another in densely developed urban areas which have closely spaced interchanges or where substantial travel demand exits between two consecutive interchanges. now Expressways Expressways are defined as controlled-access,moderate speed roadways serving intercity or intercounty trips. Awaw This class of facilities is devoted entirely to the task of traffic movement,and performs limited land service function. Intersections may be at grade. The following design standards shall apply to expressways: 1. Opposing travel lanes shall be separated by a median if there are two or nx=travel lanes in each direction. 5-10 5.Transportation and Circulation Element 2, Access shall not be permitted from abutting parcels;however,access maybe allowed prior to iniproveinent of roadway segments to expressways standards if there is no alternative access route to a parcel. 3. Intersections with median breaks shall occur only at arterials or other expressways. 4. Acceleration and deceleration lanes may be provided at intersections. is r: o °O rrr r • ers•� O° • s � ' � R • waw ewe • • ••• -� / °° ab ° Q ... •� 0600 O°O a �^ °o ° U w d� a rr •.r• • i t ! • • i• e • • f F ! • r r•• '"w•faew � r r _ co o C o .•, ' 4• 0 N N {,n W a U1 0 C4 a> t7 ttS N r� Q ow �ee A` #low • _ e 0 � • cd E e r _ ■ • • o r r r • r • � /11 .

Their traffic function is of county-wide or intercity importance,rather than serving primarily local area traffic. Arterials mainly serve to move traffic,but they normally also perform a secondary land service function. 1 Access from abutting parcels may be allowed but shall be secondary to protection of the traffic serving function of the roadway. Driveways and parking shall be restricted or may be prohibited altogether to improve capacity and safety. 2. Opposing travel lanes shall generally be separated by a median if there are two or more travel lanes in each direction. 3. Turning lanes and deceleration/acceleration lanes shall be provided at intersections with roadways designated as arterials,or collectors,and are desirable at other intersections. 40 Rights-of-way at approaches to intersections with other arterials shall be sufficient to accommodate dual left-turn lanes. 5. Signalization shall generally give priority to through-traffic on the arterial. Collectors Collectors are for internal traffic movement within a community, carrying traffic to arterials and between neighborhoods. They are low speed roadways that do not ordinarily carry a high proportion of through trips and are not,of necessity,continuous for great lengths. Collectors may also serve to provide access to property, especially in rural areas. Access from abutting parcels in residential areas shall be discouraged. Driveways and parking may be restricted. Local Roads Local Roads are low speed,low capacity roadways that provide circulation within neighborhoods and access to adjacent land. Street design standards and layouts are used to discourage through traffic movements,avoid high travel speeds and volumes,and minimize neighborhood noise and safety impacts. Curbside parking is usually allowable. TRANSIT NETWORK CONCEPTS The Transit Network Plan corit lates,two different roles for public transportation: 1)provision of basic mobility for those individuals without access to automobiles or who are otherwise transit dependent;and 2)provision of an alternative means of travel for individuals with access to automobiles,especially peak-period conunuters. The Traftsit Network Plan establishes local transit service areas;areas where development densities will warrant the provision of fixed-route transit service by 20052020. Fixed-route transit operations are the prirY try means of serving the basic mobility needs for transit dependent individuals in urban areas of the County. The Plan assumes additional local bus service to BART stations,as well as the LMlementation of the e-BART concept from the.PittsbW-v_/Bav Point BART 4 DittsLums anci A ntioniq A%%J'AL JLL&T'X%.R%."LJL0 station to Byrome. 4 The Transit Network Plan establishes transit corridors along the county's freeways in order to provide speedconvenient and reliable alternatives to driving alone on congested freeways. Within these corridors,the County will pursue the construction of rail transit ek.-tensieffis service and high occupancy vehicle facilities,the establishment of express bus service,the integration of rail transit and bus service,and the promotion of carpools and vanpools. Existing and proposed studies will identify the feasibility of improving specific transit operations in A%0.9.1 XW A A 16 9.1 DI the Transit Corridors.

Cooperate with MTC in its effort to increase tolls on regional bridges serving the County to help pay for alternative transportation service. 5.7 TRANSPORTATION DEMAND MANAGEMENT Transportation Demand Management(TDM)is oriented towards encouraging efficient use of existing transportation facilities during peak periods of travel TDM recognizes that large scale investments in highway and transit facilities are frequently limited by the availability of financial resources and adverse commnw reactions. TDM measures usually.l) involve lower capital costs; 2)provide incentives designed to modify travel demand; 3)are implemented by local government or the private sector,and 4)give all travel modes equal consideration in providing access to development~ The County currently promotes TDM strategies in unincorporated areas through certain County ordinances. Even with substantial investment in transit facilities, driving alone is likely to remain the choice of most county residents who commute. The County should continue to monitor the effectiveness of its zonine and 5-21 5.Transportation and Circulation Element subdivision ordinances to ensure that new development promotes a balanced transportation system and does not solely rely on the automobile.

Development of a comprehensive bikeway system within these areas would provide further incentive to commute by bike. A comprehensive bikeway system is defined as a system of bike paths,bike lanes,and bike routes interconnected f-- and spaced closely enough to satisfy the travel needs of most cyclists. Many existing bikeways are of a recreational design combined with pedestrian trails and located off-street. These facilities should be supplemented by on-street commuter bikeways that provide direct access to commercial uses. NNOW "Bikeway"means all facilities that provide primarily for bicycle travel. The following categories of bikeways are defined in the California Streets and Highway Code. ANWW o Class I Bikeway(Bike Path or Bike Trail):Provides a completely sepated right-of-way designated forthe exclusive use of bicycles and pedestrians with cnossflows by minin�iz�ed. o Class H Bikeway(Bike Lane): Provides a restricted right-of-way designated for the exclusive use or semi-exclusive use of bicycles with through travel by motor vehicles or pedestrians prohibited,but with vehicle parking and crossflows by pedestrians and motorists permitted. o Class III Bikeway(Bike Route): Provides a right-of-way designated by signs or permanent markings and shared with pedestrians or motorists. .•.. .In.M,u ch of 2002 the Contra Costa Transporaition Authori initiated a cooperative effort«l-ith the cities and the coirnt�tc? piWare a Count de Bi 1e and Pedestrian.Plan.

This plan has two basic purposes: it enables the County to request that the State designate state routes to the State highways program,while at the same time providing a local scenic route implementation program. Such a plan provides recognition of the perception we have of our surroundings while traveling through the County. Presently Contra Costa County has numerous roadways that pass through areas affording pleasurable views. The number of such roadways where scenic quality exists will diminish,however,unless protected. Their character is changed through improvements to them or when land adjacent to them is developed. This plan identifies a Countywide scenic route system and ensure that new projects approved along a scenic route are reviewed to maintain their scenic potential. Most scenic routes depend on natural landscape qualities for their aesthetics and many formally designated scenic routes have been established in predominantly rural areas in the past,but neither natural beauty nor rural settings are necessary to the designation of scenic routes. DEFINITION AND MAPS OF SCENIC ROUTES For the purposes of this plan, the following definitions will apply; they should aid in understanding the relationship of the scenic roads to their environs. A scenic route is a road,street,or freeway which traverses a scenic corridor of relatively high visual or cultural value. It consists of both the scenic corridor and the public right-of-way. The public right-of-way includes the roadbed and adjacent lands in public control. It includes lands utilized for roadway protection,storm drainage,public utilities,pedestrian travel,and roadside plantings. Usually this land is owned in fee or dedicated to local jurisdictions or the State. It should also include cycling or hiking trails,roadside rests,or turnouts,etc. Public projects in the right-of-way should be designed and carried out recognizing the purpose of this plan. Semi-public rights-of-way include railroads,canals,or power transmission lines. A scenic corridor is usually much wider than the road right-of-way and extends to the contiguous areas beyond it. Width of scenic corridors will vary greatly depending upon the present degree of development, land forms, topography,and the nature of scenic quality. The scenic corridor consists of much of the adjacent area that can be seen from the road. It is within this area that development controls,dedication,and the purchase of easements or lands in fee simple will be required,and public projects will be reviewed for compliance with this plan. Controls should be applied to retain and enhance scenic qualities,restrict unsightly use of land,control height of structures, and provide site design and architectural guidance along the entire scenic corridor. Route 24 from the Alameda County line to the Interstate 680 interchange,and Interstate 680 south of that interchange to the Alameda County line,are existing State designated scenic routes within the State Scenic Routes program. Route 4 from Hercules to the intersection with Railroad Avenue is proposed for State designation as is the proposed State Route 94.Bypasis to the Delta. While the State Scenic Routes plan forms the skeletal ork for the County Scenic Routes program,Figure 5-4 identifies the other roadways which form the Countywide scenic routes plan.Inclusion on this map provides direction to 1 -C9on staffto review projects m a fashion which is compatible with the scenic qualities ofthese roads. Scenic routes are shown for the unincol rated-cu:eas:routes with scenic potential or to connect scferntc areas are shown as conn .. ectingroutes.

Additionally,there are ._ several private airfields which operate in the county and requests for heliports have been received from time to time. This section adds policies to the County General Plan which guide the use of airports,private airfields and heliports. The overall goals and policies for airport and heliport operations in the county are outlined in the next two sections. A more detailed description and policies for Buchanan Field and the East.t . w*Byron Airport are included in separate sections below. Finally, special policies required by the Airport Land Use Commission are included following the ._.. discussion of the two airports. The noise contours for these airports are included within the Noise Element of this Plan. AIRPORTS AND HELIPORTS GOALS 5-S. To encourage the development and operation of two general purpose public airports in the county. 5-T. To allow heliports,restricted to appropriate locations, that would add to the economic well-being and safety of the county. AIRPORTS AND HELIPORTS POLICIES MOMW Overall Policies 544. Regulate the location of private airfields and heliports to minimize their impacts on adjacent residents, sensitive receptors,and to ensure public safety. --r 545. Protect the Byron Airport environs from urban encroachment through a combination of land acquisition, easement acquisitions and land use regulations. ... 546. Work with adjacent cities to ensure that Buchanan Field Airport environs are developed and redeveloped in ways which protect the public safety and maintain the viability of the airport. 547. Work with the FAA and helicopter operators to minimize conflicts with residential areas and sensitive land uses, such as schools,hospitals,residences,and other sensitive noise receptors. Policies Regarding Buchanan Field Buchanan Field is located on a X95 acre site in the unincorporated area of Contra Costa County adjacent to the cities of Concord and Pleasant Hill;a very small portion of airport pmoperiy is located within Concord. It is a general use airport and has provision for scheduled commuter airline service. The land use plan designations for this airport are shown on the Land Use Element map. Land uses allowed on Mow the airport property should enhance the airport function and be consistent with its goals and operational requirements. Most of the site is designated "Public/Semi-Public"to reflect the airport use.—� 4a Special policies of this plan that apply to Buchanan Field are as follows: SNOW 548. The Transportation and Circulation Element requires the construction of the Diamond Boulevard extension from Concord Avenue northerly to Center Avenue as a condition of approval of development projects on the western side of the airport to major new uses. 549. The Buck Field Golf Course exists on the southwest edge of the airport adjacent to the intersection of Concord Avenue and I-680. The road improvements called for by this plan,and in particular the Diamond -- Boulevard extension, will require modification to the existing golf course. This plan encourages the 5-26 "� 5.Transportation and Circulation Element maintenance of a small golf course or some other recreation facility in the location of the golf course. 5-50. Passive recreational uses are appropriate in the approach path of the airport and will constitute an environmental enhancement and balance to serve as amenities for the development at the airport. Some maintenance responsibilities for these recreational facilities may be required of the airport projects. 5-51. Trail connections surrounding the airport are required. A riding,hiking and bicycle trail is shown along the Walnut Creek Flood Control Channel. Hiking and bicycle trails are shown flanking the airport on its remaining perimeter. These trails will serve as an amenity to the new office facilities in the area,as well as providing a connection to a regional trail linkage along the Walnut Creek Channel. ContraEast •Byron Aires The County has developed a -full-service general aviation airport ata site adjacent to the e:-moo Town of ByronAir ffiL The project location is approximately three miles south ofthe town ofByron and 2%2 miles north ofthe Alameda County line. The Byron Highway passes one mile to the northeast. Long range plans call for construction of a runway capable of serving 250,000 operations annually,and construction of parking to accommodate 250 aircraft. The airport acquisition and development was jointly funded by the County,the State and Federal Governments. The airport boundaries encompass 1307 acres of which only 230 93 acres will be available for airport and compatible purposes. In addition to the land to be acquired in fee,an additional 2,000 acres of conservation easements may be acquired to preclude additional residential development and to control noise,height of structures,etc. In addition, aviation easements within two miles ofthe airport will also be acquired,later if needed,to assist in controlling development. The expressed intent of the County is to have a second airport free from urban encroachment,and to prevent the establishment of related commercial or industrial development around the planned airport Water and sewer services will be limited to serve only the airport;utilities will not serve growth on the adjacent properties. It is also for this reason that extra rights-of-way beyond the airport development proper are being acquired. Additionally,no residential development or sensitive receptors, e.g. hospitals,schools,etc.,should be allowed within the projected 60 CNEL noise contours for the new airport. (For information only,Measure C-1990 provides that one of the enumerated bases for changing the Urban Limit Line,upon a4/5 vote,substantial evidence and public hearing,would be the following finding. (f)an objective study has determined that a change to the Urban Limit Line is necessary or desirable to further the economic viability of the East Contra Costa County Airport,and either(i)mitigate adverse aviation related environmental or community impacts attributable to Buchanan Field, or(ii)further the County's aviation related needs.) Special policies of this plan that apply to the East County Airport are as follows: 5-52. The County shall acquire fee title and/or conservation(development rights)easements to an appropriate amount of buffer land around the planned East County Airport. 5-53. The buffer land or conservation easements acquired around the airport shall ensure that incompatible uses will not be allowed to locate within the safety zone. 5-54. Establishment of commercial,industrial or residential development around the planned airport shall not be allowed 5-55. Water and sewer services to the airport will be limited to serve only the airport properties; utilities will not serve growth on the adjacent properties. 5-56. No residential development or sensitive receptors,e.g.hospitals,schools,etc.,shall be allowed within the projected 60 CNEL noise contours for the new airport. Special Policies Regarding the Airport Land Use Commission The Public Utilities Code requires that the intent and purpose of adopted Airport Land Use Commission(ALUC)plans and policies be incorporated into the County General Plan. The following policies apply to the two County airports: 5-57. Structural heights shall be designated by the Federal Aviation Regulations(FAR)Part 77 surfaces associated with the various runway designations shown on the latest Airport Layout Plan. 5-58. The Structural Height Limits defines maximum structural height. Height limits will be placed on new 5-27 5.Transportation and Circulation Element buildings,appurtenances to buildings,all other structures and landscaping in accordance with the Airport Layout Plan except in special instances when for reasons of safety the Commission may impose a more restrictive structural height. An applicant for any structure within the Airport Land Use Commission Planning Area proposed to penetrate any height limit surface shall submit an aeronautical analysis which specifies the proposed project's effect on airport instrument procedures for all runways,the effect on airport utility,and the effect on overall aviation safety. If,after reviewing the aeronautical study and other related information,it is determined that the proposed project would not have an adverse effect on safety and airport utility then,the project may be approved for heights other than those indicated by the FAR,Part 77,Structural Height Limits. 5-59. All major land use actions within the Buchanan Field and Byron Airport Influence Areas as shown upon Figure 5-5 shall be referred to the Contra Costa County Airport Land Use Commission for comment. The definition of what constitutes a major land use action is found on pages 2-6 through 2-8 of the Contra Costa County Airport Land Use Compatibility Plan adopted in December of 2000. If it is unclear whether or not an action falls within this listing,the County should err on the side of caution and refer the matter to the ALUC staff. Gomm 5-60. New construction or building exterior alterations located in areas of terrain penetration as defined by the ALUC Airspace Protection Surfaces will be reviewed on a case by case basis with consideration given to topography,flight patterns,existing vegetation and other factors which might affect airspace and safety. The County will rely on ALUC land use compatibility guidance and programs for considering airspace safety analysis issues and height limitations of structurers. 5-61. Temporary structures,such as construction cranes or antennae,which would penetrate any adopted height limit surface,may be allowed after a case by case review,provided that obstruction lighting and marking is installed and a two week notice of temporary structure emplacement is provided by the proponent to the County Manager of Airports. Temporary structure emplacement shall be subject to reasonable time limit. 5-62. The County may require an exterior building materials reflectivity analysis upon review of the proposed types of building materials, building height, and building location and use on site. Such analyses should be required for development of any structures on or adjacent to public airports which would be over three stories in height and utilize reflective surfaces. Reflectivity studies shall address the potential for pilot and airport operation interference,proposed mitigation to any identified potential interference resulting from reflected sunlight,and any other subject areas related to reflectivity which the County may deem appropriate. The County may include some or all of the proposed mitigation in its project approval process. " 5-63. Within each safety zone designated by the ALUC, the following are incompatible uses (The ALUC Airport Influence Area Maps for Buchanan Field Byron Airports are shown on Figure 5-5.): (1) Any light source which would direct a steady light orming light of red,white,green,or amber color associated with airport operations toward an aircraft engaged in an initial straight climb following takeoff or toward an aircraft engaged in a straight final approach toward a landing at an airport,other than an FAA approved facility. (2) Any construction which would cause sunlight to be reflected toward an aircraft engaged in an initial straight climb following takeoffortoward an aircraft engaged in a straight final approach toward a landing at the airport. (3) Any use which would generate smoke, attract large concentrations of birds, or may otherwise adversely affect safe air navigation within a safety zone. (4) Any use which would generate electrical interference that would be detrimental to the operation of aircraft and/or aircraft instrumentation. (5) Any use which would utilize or cause to be stored highly toxic,inflammable or otherwise hazardous materials which, in the event of an aircraft accident, could be released into the surrounding ..._ environment to threaten human life or property. (6) Within the safety zone clear area,any use which involves the erection of a permanent above ground structure other than FAA approved facilities. -- (7) Within the safety zones,excluding the clear areas,any use which on a regular basis would result in a density(excluding streets)in excess of 30 persons per acre or one person/500 square feet of gross 5-28 AN& 5.Transportation and Circulation Element building flood area,whichever is less. (8) Any of the following uses:new single and multiple family residences,shopping centers,restaurants, schools,hospitals,arenas and other places of public assembly. 5-64. The following are suggested uses within the ALUC Compatibility Zones for Buchanan Field: (1) agriculture; (2) open space; (3) warehousing; (4) light industry; (5) parking of automobiles;and (6) low occupant density public uses,such as sewage treatment plants. 5-65. Within the ALUC Compatibility Zone B-1,no new lot splits shall be allowed and buildings on existing lots of record shall be located as far as practical from the extended runway centerline and shall be limited to two stories in height. The following are suggested uses within the ALUC Compatibility Zones for the East Contra Costa Airport (1) agriculture; (2) open space; (3) low intensity park and recreation uses; (4) low occupant density public uses;and (5) parking of automobiles. 5-66. Airports and heliports may be allowed by issuance of a land use permit in zoning districts found by the Board of Supervisors to be suitable for such uses. 5-29 AL cr10. z:1 4 .................

Review county ordinance code provisions and consider the suitability of each zoning district for the establishment of airports and heliports. 5-aq. Continue to regulate all heliports in the county by the land use permit process. 5-ar. Create a new zoning district to regulate private land use on the two public airports. 5-as. Undertake hearing to rescind the"Airport Zoning Plan for Buchanan Field"adopted in 1955,and to approve preparation of an updated structural height limit plan. 5-atiat. The subdivision ordinance should be amended to require the following actions prior to recording a final map for the ALUC Planning Area: (1). Dedication of suitable aviation and noise easements for the area of the particular subdivision; (2). Require the developer to record a covenant or provide other nis rwinAstom*prospective buyers of lots that the property may be subject to frequent overflight and associated noise impacts. 5-a=au. Any project in an area near the Buchanan Field airport with a designated noise level of 60 BA decibel CNEL or greater as shown on the Projected Noise Levels Map shall be required to attach a statement to any deed, lease,rental agreement, or Covenants, Conditions and Restrictions document pig to the use of the pry. The statement shall indicate that the property is subject to aircraft overflight,and associated noise irripacts. 5-agar An acoustical study shall be required for any discretiormyresidential project which the County will consider which is within the area designated on the Projected Noise Levels map to exceed 60 dBA level. The study should be submitted prior to accepting the application as complete and shall be by a certified noise acoustical firm. 5.11 PORTS AND PROPRIETARY WHARVES INTRODUCTION Contra Costa has historically been oriented to its waterfront,since the western end of the County is located on San Francisco and San Pablo Bays,and the northern shoreline fronts along the Carquinez Strait, Suisun Bay and the Sacramento San Joaquin River Delta. Industrial development in the county was concentrated along the shoreline,and this legacy remains today with port-oriented heavy industrial uses located in scattered locations from Richmond to Antioch. These industrial uses are important to the county economic base and the continued use of appropriate shoreline areas for heavy industries that rely on water traffic should be protected. There is one major deep water port in the county,the Port of Richmond,located in that city.

The Southern Pacific railroad .� line,now owned by�'��T �~ y��� �����'�'nn�� Union:Pacific(LJP).stretches 60 miles from Richmond to the Alameda County line near Clifton Court Forebay. The WUP line is a high speed double track between Richmond and Martinez,and carries by far the most freight traffic of all the railroad corridors in the County. From Martinez,the 8RUP track splits,with one track crossing the river to carry freight up the S.�ento Valley to the northwestem U.S.,and one track(kno«n as tile"Mcxoco.tine")continuing through Antioch,Oakley,Brentwood,Byron Trac ,and into the San Joaquin Valley and points south. The:Moc(xo line is seldom used by U.P and niay be acquired by BART for operation of a planned conlinuter rail ser--ice in East Couii!yl. The 55-mile long Burlingrton Nor-theni Santa Fe (' BNSF)railroad corridor roughly parallels the SUP line between Richmond and Hercules,where it then turns inland through rural Franklin Canyon �. running south of Route 4 to the industrial areas east of Martinez. From there it again closely parallels the&RUP(and Sacramento Northern/Union Pacific)tracks as it passes through Pittsburg and Antioch,and then through Oakley and across the Delta to Stockton. . ' -U. • , .� .. Two smaller freight lines also operate in the County. Union Pacific controls the subsidiary Sacramento Northern line from Clyde to Pittsburg, and the Bay Point and Clayton rail line serves the T' tea An1iy's Military Traffic;:Management Command. The other major railroad corridor in the county,the SP tracks running north-south between Concord and through the San Ramon Valley to the Alameda County line,was abandoned in the 1960s and has been largely acquired by the County�•ith the assistance o state funds res er.,ed for implementingr,mass transit systems. This abandoned SP San:Ranson Valley Branch Line is now Imo;y1 as the Iron Horse Corridor. CulTently it is used as a trail by pedestrians and bicyclists.and for pipelines and utilities operated by Dublic and pfivate entities. The Counly is d.evelo 1in T a management pro gmm for the Iron Horse Corridor. starting witll a Landscape Element that wws approved by the :Board of Superyisors in 2000. The County's management pro ant reserves a portion of the Iron.Horse Corridor for future use as a rail transportation line,per the requirements of the state wants that enabled the Count; to o acquire the richt-of-way. The poi tion.of the Iron Horse Corridor that is used as a trail is maintained by the East Bay Regional Park District.

A41. thesieRail lines are directly involved with the economic vitality of the County,since numerous industries depend on the rail movement of heavy goods such as oil and chemical products,coal,lumber,and automobiles, as well as containerized cargo. The importance of railroad lines is further increased by the growing ridership of intercity passenger trains serving the County, and future plans for urban, commuter, and intercity rail passenger service to provide alternatives to the region's freeway congestion.

HOUSING ELEMENT 6.1 INTRODUCTION The development and preservation of housing is important to all the people within Contra Costa County. To plan for the development of adequate housing for all income segments, a housing element is Im pared as a part of the Geneml Plan. This document constitutes the Housing Element,which specifically addresses housing needs and resources in the • County unincorporated areas. Section 6.1, Introduction of this Element reviews the geographic areas covered by the Contra Costa County Housing Element, the purpose and content of the Element, the public participation process undertaken to assist in the development of the Element,and its relationship with the rest of the General Plan. A. Community Context 11 County Geography Established in 1850, the County of Contra Costa is one of nine counties in the San Francisco Bay Area. The County covers 733 square milesof`land area and extends from the northeastern shore of San Francisco Bay easterly to San Joaquin County. The County is bordered on the south and west by Alameda County and on the north by Suisun and San Pablo Bays. The western and northern communities are highly industrialized,while the inland areas contain a variety of urban,suburban/residential,commercial,light industrial,and agricultural uses. Contra Costa County is comprised of large unincorporated areas and the cities and towns of Antioch,Brentwood,Clayton, Concord,Danville,El Cerrito,Hercules,Lafayette,Martinez,Moraga,Oakley,Orinda,Pinole,Pittsburg,Pleasant Hill, Richmond, San Pablo, San Ramon,and Walnut Creek. The unincorporated areas include the following communities: Alamo,Bayview-Montalvin Manor,Bay Point,Bethel]sW4 Blackhawk,Byron,Canyon,CrockM Diablo,Discovety Bay,East Richmond Heights,El Sobrante,Kensington,Knights n,Mountain View,North RichrnoricL Pacheco,Pleasant Hill BART, Rodeo, Rollingwood,Tara Hills, and Vine Hill. The incorporated cities and towns are separate political entities;the unincoporated areas are within the land use jurisdiction of the County government. The County is large and diverse. It encompasses several housing sub4narkets,which we determined by a combination of topography, historical development patterns, and social and economic phenomena. In general, the County can be divided into three primary subregions—West,Central,and East West County is urbanized with a developed industrial base. Central County is a rapidly urbanizing area with much new office and light industrial development East County has historically been y agricultural but is now experiencing considerable residential development Figure 6-1 illustrates the geographic relationship between the cities and towns and the unincorporated areas. This Housing Element is concerned with the housing needs,constraints,resources,and solutions for the unincorporated areas. 2. County Residents The 2000 Census indicates that Contra Costa County is home to 949,000 residents,making it the ninth most populous county in California. Several cities experienced - Li4flucc-urit population growth during the last decade. In particular, the City of Brentwood population tripled in ten years,experiencing a growth of 2080/6. Other connnunifies with significant growth include Clayton(47%).Antioch(46%).Oakley(390/6),Danville(33%).,and San Ramon(27%). 71be uninco ted areas of the County had a population of 151,690 in 2000,repmmmtirig an increase of 14%since 1990. Countywide growth was 18%during the same period. Residents have been athacted to Contra Costa County in the 1990s xfinarily due to the availability of rapid trarisit,close proximity to major employment centers in Oakland,San Francisco,,and the Silicon Valley, as well as employment growth within the County along the 1-680 corridor and Tri-Valley area. The relatively affordable housing prices in the County compared to other Bay Area counties also contribute to the population growth. Like the rest of the Bay Area, the County has become more edinically diverse in recent decades. The number and proportion of Hispanic and Asian residents have increased considerably,according to the 2000 Census.' The number of families is also growing in the County, indicating the continued need to provide adequate affordable housing, including first-time homebuyer and move-up housing opportunities. VA�ile the number of Black residents has increased,its proportion of the County population has remained at slightly over 9%. 6-1 6. Housing Element Contra Costa County has one of the fastest growing work forces among Bay Area counties,with growth in its employment base driven primarily by the need to provide services to an*increasing local population. Nevertheless,the number of white- collar jobs has increased in the County due to the decentralization of office-related employment to the County from other parts of the region,particularly San Francisco. However,the Association of Bay Area Governments(ABAG)expects that Contra Costa County will continue to provide"bedroom communities"for the workforce of other Bay Area counties. The County is expected to gain nearly 23,000 more employed residents than jobs between 2000 and 2020. 3. County Housing Market Single-family homes are the predominant housing type in the County. This is especially true in the unincorporated areas, where single-family dwellings comprise 80%of the housing stock. Multi-family units account for 14% of the housing units.,while the iernairung 6%are mobile homes. Although home prices are more affordable in Contra Costa County than m most areas in the Bay Area,housing affordability is still an important issue affecting many residents in the County. A significant number of lower- and moderate-income households spend more than one-third of their incomes on housing.2 This level of housing payment is typically considered as burdensome to lower-and moderate- income households and suggests that income growth has not kept pace with the increase in housing costs. Neighborhood and housihg quality is another issue in unincorporated County areas. About 46%of the housing stock in unincorporated areas is thirty years or older, the age when most homes begin to have major repair or updating needs. In particular, significant housing rehabilitation needs have been identified in the Bay Point, North Richmond,and Rodeo redevelopment project areas. Contra Costa County is faced with various important housing issues: preserving and enhancing the affordability of housing for all segments of the population; providing new types of housing in response to changing demographic trends; L",Arm and improving the quality of the housing stock;and achieving a balance between employment and ' housing opportunities. This Housing Element provides policies and progxrs to address these and other related issues. B. Role and Content of Housing Element Ae availability of housing is of vital The Housing Element of the General Plan has two purposes: statewide importance, and the early (1) to provide an assessment of both current and future attainment of decent housing and a housing needs and constraints in meeting these needs;and suitable living environment for every (2) to provide a strategy that establishes housing goals, California family is a priority of the hi policies,and programs. hest order.g This Housing Element represents Contra Costa County's long-term California Government Code, Section commitment to the development and improvement of housing with 65580 specific goals for the short term,, 2001-2006. This Element identifies strategies and programs- that focus on: (1) preserving and improving housing and neighborhoods; (2) providing adequate housing sites; (3) assisting in the provision of affordable housing; (4) removing governmental and other constraints to housing investment;and (5) promoting fair and equal housing opportunities. The Housing Element consists of the following major components: • An introduction reviewing the purpose and scope of the Element(Section 6.1); • An analysis of the County's demographic profile,housing characteristics, and existing and future housing needs(Section 6.2); • A review of potential market, governmental, and environmental constraints to meeting the County's identified housing needs(Section 6.3); • An evaluation of the land, financial, and organizational resources available to address the County's identified housing needs goals(Section 6.4); • An evaluation of accomplishments under the adopted Housing Element(Section 6.5);and • A statement of the Housing Plan to address the County's identified housing needs, including housing goals,policies and programs(Section 6-6). 2 -1be S=e Dep=MM Of I-JOUSn and GDMMMMty Development {HCS) has established four income categories based on County median fz* uxorne(RFS. Very low-mcorrie households am those eammg uxonr up to 50%of the County MR. Low-income households am those eammg 51 to 80% of the County MR. Combined,the very low- and low-income households are referred to as lower-income households. Maden to-income households am those eaming 81 to 120P/o of the CmmyMFI. Upper-income households am those earning more than 120%of the Cerny MR. 6-2 ,v C + afi� � . . . U) w .. .I -I I I . tQ� , � tai ; I..... . NO& ft- .�4 :. s* ; 9 *. I . �" •; .:, . .:.:,::..::.:..

Housing Element C. Data Sources Various sources of information are used to prepare the Housing Element. Data from the 1990 Census on population and housing are used to a large extent in the Element. Although dated, the 1990 Census remains the most comprehensive and widely accepted source of information until detailed data from the 2000 Census is available. Where possible, preliminary data from the 2000 Census have been incorporated in the Element. Several data sources are used to update the 1990 Census and supplement limited 2000 Census information: • Demographic and housing data provided by the Association of Bay Area Governments and the State Department of Finance; • Housing market information, such as home sales,rents,and vacancies, is updated by surveys and property tax assessor's files, • Public and nonprofit agencies are consulted for data on special needs groups, the services available to them,and gaps in the system;and • Lending patterns for home purchase and home improvement loans are provided using the Home Mortgage Disclosure Act{NMDA)database. D. Public Participation The County encourages the participation of residents and local agencies in the process of identifying housing needs and formulating housing policies and progrya i . During the development of the Housing Needs Assessment(Section 6-2), the County consulted with and/or obtained information fi-om a variety of organizations serving low- and moderate- income persons and those with special needs. These agencies are referenced throughout the document. In gyration of the Housing Element,opportunities were provided for the public to help shape the County's housing goals,policies,and strategies. Two publicly noticed study sessions for the Planning Commission were held to discuss 4MOM housing needs and community concerns and discuss and policies, respectively. Over 300 groups and individuals were notified of the study sessions,including representatives fivin the following general categories: • Board of Supervisors/County departments • County cities and towns • Other local,State,and federal government agencies and special districts • Transportation committees • Municipal Advisory committees • Chambers of Commerce • School districts • Libraries • Housing developers/advocates • Real estate associations • interfaith groups • Interested individuals • News media Specific agencies were contacted directly to encourage in the study sessions. Private citizens and mIxesetitatives from for-profit and non-profit housing developers and service agencies ceded the study sessions.Public input received has been incorporated into the Draft Element for review by the State Department of Housing and Community Development(HCD). In addition,County staff spoke on the Draft Housing Element at meetings of the following groups: • Area Office of Aging • Contra Costa Interfaith Coalition • Mobile Home Advisory Committee • Faith Works! • Contra Costa Continuum of Care Board To adopt the Housing Element, public hearings were held before the Planning Commission and County Board of %mom Supervisors. Notices were published in local newspapersin advance of each hearing and copies of the Draft Element were made available for public review at selected County government offices,public h-braries,and other public locations in the unincorporated areas. Drafts of the Housing Element were also posted on the County website at www.cocoplans-org. 64 6. Housing Element E. Relationship to the General Plan The 2001-2006 Housing Element is a key component of the County's General Plan. The County of Contra Costa adopted its General Plan in 1991, which includes the following elements: Land Use; Growth Management-, Transportation and Circulation;Housing;Public Facilities/Services;Conservation;Open Space;Safety-,and Noise. The Housing Element Wilds upon the other adsting General Plan Elements and is consistent with the goals set forth in those elements. The Housing Element goals should be interpreted and implemented consistent with other General Plan goals. A consistency matrix identifying the related goals is provided on the following page. For each housing goal presented in this Housing Element,the related goals in each General Plan Element are identified by number. For example,Goal 3-D in the Land Use Element calls for"[the provision ofl a range and distribution of land uses that serve all social and economic segments of the County and its subregion." This Land Use Element goal is consistent with the intent of Housing Element Goals 4,6,and 8 reliating to the provision of a range of housing choices to all social and economic segments of the population. The County will ensure consistency between General Plan elements so that goals and policies introduced in one element are consistent with other elements. If it becomes apparent that over time, changes to any element are needed for internal consistency,such changes will be proposed for consideration by the Planning Commission and County Board of Supervisors.

To accomplish this goal,a comprehensive assessment of the housing needs of the region must be conducted. Section 6.2,Housing Needs Assessment presents and analyzes the demographic,socioeconomic,and housing characteristics of the unincorporated County areas to determine the nature and extent of housing needs. Until the detailed 2000 Census data are available,the 1990 Census remains the most comprehensive and widely accepted source of information for describing the demographic,housing and socioeconomic profiles of a community. As such,data 6-5 6. Housing Element from the 1990 Census are used to a large extent in this housing needs assessment. Where possible,the 1990 Census and mom& preliminary 2000 Census data are supplemented with current market data and secondary sources of information. A. Population Characteristics The type and amount of housing needed in a community are largely determined by population growth and various demographic variables. Factors such as age, race/ethnicity, household size, occupation, and income combine to influence the type of housing needed and the ability to afford housing. 1. Population Trends Contra Costa County is the ninth most populous county in California,with its population at approximately 949,000 as of the 2000 Census. This represents an increase of 18% since 1990. Major factors that have contributed to attracting more residents to the County in the 1990s include: the availability of rapid transit; close proximity to major employment centers in Oakland and San Francisco; relatively affordable housing prices in the County; and development of new employment centers along the 1-680 corridor and Tri-Valley area. The Association of Bay Area Governments(ABAG)projects that the County will have 1,021,500 residents by 2005 and 1,076,800 by 2010. While the population of every city in the County increased during the 1990s,population growth has been the strongest in the East County,particularly in Antioch,Brentwood,and Oakley. According to ABAG,East County and San Ramon will account for much of the household growth between 2000 and 2020. (East County includes Antioch,Pittsburg,Brentwood,Bay Point "mom Oakley,and Rural East Contra Costa County. The San Ramon Valley includes the unincorporated community of Dougherty Valley.) Substantial growth is also expected in Bay Point an unincorporated community within Pittsburg's sphere of influence, as the Pittsburg/Bay Point BART(Bay Area Rapid Transit)station is the new terminus for the Bay Point/Pittsburg line. ABAG is also anticipating noticeable growth for the West County, especially for the cities of Richmond and Hercules. Redevelopable land near the new Richmond Parkway connecting 1-80 and 1-580 will help fuel growth for the Richmond area. Hercules will most likely grow due to its supply of vacant land and its location at the junction of Highways 80 and 4,which is currently under expansion. Central County will continue to absorb new housing growth,despite the diminishing supply of vacant land. Undeveloped land remains available in pockets and some communities are experiencing redevelopment in neighborhoods near the downtown and other activity centers,such as the Walnut Creek and Pleasant Hill BART Stations. In the 2000 Census, the population of unincorporated areas in Contra Costa County was reported at 151,690, representing an increase of 14% since 1990. This level of growth is lower than,that experienced by the County as a whole and by the incorporated cities and towns. However, this trend is partially a result of annexations that had occurred during the past decade,effectively reducing the geographic areas and associated population under the County jurisdiction. ABAG projects that the population of the unincorporated areas will increase to 177,000 by 2005 and to 185,900 by 2010. In Table 6-1,the population of unincorporated areas in the County by region(sub-area)is shown.

The Central region had the largest population of the three unincorporated sub-areas in both 1990 and 2000. During the 1990s, the population of this sub-area increased significantly (29%), from 50,134 in 1990 to 64,920 in 2000. In contrast,the East and West regions grew by only 6%and 3%,respectively. As of 2000,the East and West regions had a population of 41,891 and 44,879, respectively. Specifically,unincorporated communities that are census-designated places(CDPs)which grew most dramatically in the 1990s include Blackhawk(62%)and Discovery Bay(68%). -MONO 2. Age Characteristics A community's current and future housing needs are determined in part by the age characteristics of residents. Typically, each age group has distinct lifestyles, family type and size, incomes, and housing preferences. As people move through each stage of life, their housing need and preferences also change. As a result, evaluating the age characteristics of a community is important in determining the housing needs of residents. 6-6 6. Housing Element Table 6-2 provides the age characteristics of residents in the unincorporated areas and the County as a whole in 1990. As shown, the age composition of unincorporated area residents was very similar to that Countywide. According to the 1990 Census, the largest age group in the unincorporated areas was young adults at 34%,followed by middle age residents at 22%,the school age population at 17%,and seniors at 11%. Table 6-2 Age Characteristics Age Groups Unincorporated County Total County Persons Percent Persons Percent Preschool(Ag s<4) 9.)469 7% 60,743 8% School Age(5-17) 23,1005 17% 141,345 18% College Age(18-24) 11.)390 9% 721,259 9% Your Adults(25-44) 45.)421 34% 282,171 35% Middle Age(45-64) 29.)577 22% 159,1718 20% Senior Adults(65+) 14?202 11% 87,496 11% Total 13,31,064 100% 803,732 100% Source: 1990 Census(2000 Census data not available). *Excludes Oakley both in 1990 and 2000—Oakley incorporated in 1999. A high proportion of young adults generally indicates a need for rental units and first-time homebuyer or first move- up opportunities, including condominiums, town homes, or single-family homes. Middle age residents typically occupy larger homes and are usually at the peak of their earning power. Senior residents in Contra Costa County are mostly homeowners and typically occupy single-family homes. Nationwide trends, however, indicate that as the baby boom generation ages, the demand for move-down housing or specialized residential developments, such as assisted living facilities or active adult communities will grow. Complete age data from the 2000 Census have not been released by the Census Bureau. However, preliminary Census data indicate that 112,077 unincorporated County residents were age 18 years and above in 2000,representing an increase of 11%since 1990. Between 1990 and 2000,the number of persons under 18 in the unincorporated areas grew by 22%; their share of the total population increased from 24% to 26%. The growth of this segment of the population suggests a corresponding growth in the number of young adults and middle age persons. Preliminary Census data also indicate significant differences in the age distribution among the various communities in the unincorporated areas. Several communities have a median age well above 40, including Bethel Island(48.5), Kensington (47.1). Diablo (45.8), Port Cost (45.7), and Alamo (43). Communities with a lower median age, signifying a younger population, include Bay Point (29.1), Rollingwood (29.9), and Byron (30.5). In general, communities in the Western sub-region have a higher median age than the central and eastern sub-regions. 3. Race and Ethnicity The San Francisco Bay Area, including Contra Costa County, has been """.7 changing in the racial and ethnic composition of its population. These changes may have implications for housing needs to the extent the groups typically have different household characteristics, income levels, and cultural background that may affect their wed and references for housing. Recent studies have also suggested that different race lethtfic groups differ in their attitudes toward mid/or tolerance for"housing problems"as defined by the federal Department of Housing and Urban Development(HUD), including overcrowding and housing cost burden? According to these studies,the perceptions regWing housing density and overcrowding,as well as cultural practices of living with extended milies,tend to vary among ditfert'nt racial/ethnic groups. The population of unincorporated areas in Contra Costa County has become more diverse in recent decades. As of 2000,white residents comprised the largest racrJethnic group in the unincorporated County areas, as they were in 1990 (Table 6-3). However, the share of white population declined from 75% to 63% during the 1990s, wWe the other race/ethnic groups, especially Hispanics, grew noticeably in size and proportion. The number of Hispanic residents increased by 84%and their share of the total population grew from 10%to 17%. The number of Asian and Black residents also expanded,by 49%and 22%, respectively. The number of residents in the"All Other"category grew dramatically, largely because the 2000 Census allowed people to identify themselves as members of more than one racial group. The"All Other"category includes American Indians and Alaska Natives, and persons who identified "Some other race' and "Two or more races." As the County population becomes'increasing diverse,different types of housing should be provided to accommodate the diverse needs. Such studies include the following:"The Deterrninants of Household Overcrowding mid the Role of Immigration in Southern California"by S.Y. Choi (1993); "I"he Changing Problem of Overcrowding"by D. Myers,William Baer, and S.Y. Choi (1996);and"migration Cohorts and Residential Overcrowding in Southern California"by D.Myers and S.W.Lee(1996). 6-7 6.

The race/ethnic composition of residents varies significantly by location in the County. According to preliminary data from the 2000 Census, approximately 80%of residents of the unincorporated communities(Census designated places or CDPs)in the Central sub-region are White,compared to 51%and 52%for the East and West sub-regions. Conversely, the Hispanic share of population is noticeably higher in the East and West sub-region (29%and 19% respectively) than in the Central sub-region (7%). Also noteworthy is that Asian and Black residents comprise a greater portion of the population in the West sub-region(13%and 11%)than in other areas of the County. Specifically, four CDPs have significant proportions of Hispanic residents—Bay Point (39%), Bayview-MontavIin (31%),Tara Hills(21%)and Vine Hill(20%). Six CDPs have relatively significant proportions of Black residents— East Richmond Heights(14%),Rodeo(14%),Tara Hills(13%),Bay Point(12%),El Sobrante(10%),and Bayview- Montalvin Manor (10%). North Richmond is also known to have a concentrated Black population. Some CDPs with relatively high proportions of Asians include Rodeo (17%), Blackhawk-Camino Tassajara (17%), Tara Hills (15%),Bayview-Montalvin Manor(13%),and Bay Point(11%). Therefore,Bay Point,Bayview Montalvin Manor and Tara Hills represent the most ethnically diverse communities in the unincorporated areas. 4. Employment Employment has an important impact on housing needs. Different jobs and income levels determine the type and size of housing a household can afford. Employment growth in the region also typically results in an increase in housing demand, particularly in areas that fiuiction as a"bedroom conununity." Based on the 1990 Census,a total of 430,746 Contra Costa County residents were in the labor force, with the unemploynwnt rate estimated at 5%. According to the State Employment Development Department,the unemployment rate in the County was 2.7%in 2000.

Table 6-4 shows the types of occupations held by residents in unincorporated areas and the County as a whole. As of 1990,the two largest occupational categories were ft . and sales/technical/adrninistrati - These categories accounted for 33% and 32%of employed residents in the County's unincorporated ams, respectively. Relatively how paying jobs are in both categoiies,except for certain sales positioris,translating into higher incomes for the residents engaged in these activities. Contra Costa County has one of the fastest growing work forces among Bay Area counties, with growth in its employment base driven primarily by the need to provide services to an increasing local population. The number of white-collar jobs has also increased in the County due to the decentralization of office-related employment to the County from other parts of the region,particularly San Francisco. Now 6-8 6. Housing Element Major industries in the County include petroleum refining, telecommunications, retail and financial services, steel manufacturing, prefabricated metals, chemicals, electronic equipment, paper products and food processing. Table 6-5 identifies the major employers in Contra Costa County,which includes firms and businesses in a variety of industries. ABAG anticipates that Contra Costa County will add approximately 69,400 new jobs between 2000 and 2010. About half(51%) of this growth will be in the services sector, which will add 35,330 jobs (an increase of 27%) during the ten-year period. Other sectors that will grow noticeably over the ten-year period are the high technology, and transportation, communication, and utilities sectors. Specifically, the number of jobs in the high technology industry is projected to increase by 43%, from 6,370 to 9,130. The number of jobs in the transportation, communication,and utilities will grow by 30%,from 25,180 to 32,730.

Most manufacturing and wholesale trade jobs will be captured by Oakley,Richmond,and Pittsburg. Antioch, San Ramon, and Brentwood will experience the highest growth in retail employment. Growth in service jobs will be concentrated in San Ramon,Concord,and Richmond. The County has traditionally supported a number of"bedroom communities"for the work force of other Bay Area counties. ABAG expects this situation to continue, indicating the County will add nearly 23,000 more employed residents than jobs between 2000 and 2020. B. Household Characteristics Household vAx and size,*income levels,the presence of special needs populations,and other household characteristics UUMUTUM the qW of housing needed by residents. This section details the various household cbarxtefisfics affecting housing needs. 1. Household Type The Census defines a"household" as any group of people occupying a housing unit which may include single persons living alone, families related through marriage or blood, or unrelated persons sharing living quarters. Persons living in retirement or convalescent homes,dormitories,or other group living situations are not considered households. Household characteristics are important indicators of the type and size of housing needed in a community. The State Dqwtment of Finance estimates that 61,863 households lived in the unincorporated areas of Contra Costa County in 2000. The distribution of these households by type can be infwed from the 1990 Census since household data from the 2000 Census are not yet available. As shown in Table 6-6,the majority of households in the unincorporated areas are fitmilies,(73%). Single persons comprise 20%of households,while 7%of households were unrelated persons living together("Offiee). 4 Rural East Contra Costa County includes Discovery Bay, Bethel Island, Byron, Knightsen, and other small rural communities in the eastern part of the County. 6-9 6.

Housing need generally varies by household type. Families typically occupy single-family homes. (Approximately 80%of the housing stock in unincowated areas are single-family dwellings.) However,because of the relatively high costs of most single- f unily homes,some fimiffies,live in aptrur or condominium,units,which tend to be more affordable. Subsidized housing for lower-income families are �y available the Housing Authority of Contra Costa County and non-profit housing providers. Of the 1,149 go t assisted housing units in orated areas,909 units are for families. Single peons typify occupy smaller ap t units or condominiums,such as studios and one-bedroom units. Singlo-Pemon households may include seniors living alone,young single adults,and other individuals. 2. Household Income Table 6-7 Income is the most factor agog the Median Household Income Unincorporated Areas housing opportunities available to a household, Census Median Household the ability to balance housing costs with Designated Income as%of other basic necessities of life.

Based on projections by ABAG, the mean household income of Contra Costa County residents in 2000 was $79,000, which was the fourth highest among the nine counties of the San Francisco Bay Areas Only Marin, San Mateo,and Santa Clara counties had a higher mean household income than Contra Costa County. Income level varies significantly by location in Contra Costa County. As shown in Table 6-7, Alamo and Blackhawk in Central County are very high-income areas, with their respective household incomes more than double the County median in 1989. Discovery Bay and Kensington also had higher median household incomes than the County as a whole. Lower- income unincorporated areas include Bay Point, Bethel Island, and Pacheco. All three communities had a median income of less than 80% of the County median. Not surprisingly, these } communities also have a relatively high concentration of lower-income households based on HUD data. North Richmond and portions of El Sobrante are also known to have a high proportion of very low-income households. 5 In 1995 Dollars 6-10 6. Housing Element According to ABAG, the 2000 mean household income of residents in the unincorporated areas ranged from$61,500 in Rodeo-Crockett to $177,900 in Alamo-Blackhawk. Rural East County,which includes Sand Hill,Discovery Bay,Bethel Island,and other small rural communities in the eastern part of the County,had a mean household income of$80,600. Table 6-8 provides the income distribution of households living in unincorporated areas in 1990 and 1999. As indicated, 42% of all households in the unincorporated areas in 1999 earned upper incomes (above 120% of the County median family income or MFI). Approximately 26%of households were in the moderate-income range(81 to 120%of MFI)and 32%were in the lower(80%or less of MFI)income categories.

Special Needs Groups Certain groups have greater difficulty in finding decent affordable housing due to their special needs and/or circumstances. Special circumstances may be related to one's employment and income, family characteristics,disability, and household characteristics, among others. As a result, certain segments of residents in Contra Costa County may experience a higher prevalence of lower income,housing cost burden,overcrowding,or other housing problems. "Special needs" groups include the following: senior households, mentally and physically disabled persons, large households,single-parent households(female-headed households with children in particular),homeless persons,and agricultural workers. This section provides a detailed discussion of the housing needs facing each particular group as well as programs and services available to address their housing needs. Determining the housing issues of special need groups is easier than definning the magnitude. Because detailed data from the 2000 Census is not available as of this writing, the 1990 Census is used to estimate the size of a particular group. Recent information from service providers and government agencies is used to supplement the 1990 data. Table 6-9 the special needs groups residing in unincorporated areas of the County(excluding Oakley).

Senior Households Senior households have special housing needs primarily due to three major concerns -physical disabilities/limitations, income,and health care costs. According to the 1990 Census, 18%(8,893)of households in the unincorporated areas of 6-11 6. Housing Element Contra Costa County were headed by seniors, defined as persons 65 years and older. Countywide, there were 54,825 OWNS* elderly households. Some of the special needs of seniors are as follows: > Limited Income-Many seniors have limited incotne available for health and other expenses. Because of their refired in .6 status,one out of two elderly households(50%)1 Contra Costa County earns extremely low or very low-income > Disabilities-Of the senior population Countywide,one-third have a work disability and/or self-care or mobility limitation. > Cost Burden-Because of the limited supply of affordable housing and their limited*income,28%of senior 7 households in the County experience housing cost burden. The prevalence of housing cost burden varies "Now significantly by tenure:20%of homeowners and 62%of renters. Over 80%of elderly households(7,404) in the unincorporated areas were homeowners in 1990. Because of physical and/or other limitations, senior homeowners may have difficulty in carrying out regular home maintenance or repair activities. Elderly women are especially likely to be in need of assistance due to their physical and/or other limitations. Various programs can address the special needs of seniors, including but not limited to congregate care, supportive services, rental subsidies, shared housing, and housing rehabilitation assistance. For the frail elderly, or those with 1� disabilities, housing with architectural design features that accommodate disabilities can help ensure continued independent living. Elderly with mobility/self-care limitations also benefit from transportation alternatives. Senior housing with supportive services can be provided for those who require assistance with daily living. Social anm d supportive services aavailable in Contra Costa County dnxegh various agencies and orI (bW not *NAM& 9M limited to):the County Office on Aging,Older Adults Clinics,AlAzirrier's Disease Research Center,Health Irn==Counseling and.

Disabled Persons Physical, mental, and/or developmental disabilities may prevent a person from working, restrict one's mobility, or make it difficult to care for oneself. Thus, disabled persons often have special housing needs related to potentially limited earning capacity, the lack of accessible and affordable housing, and higher health costs associated with a disability. Some residents suffer from disabilities that require living in a supportive or institutional setting. The 1990 Census defines three types of disabilities: work,mobility, and self-care limitations. Disabilities are defined as mental,physical or health conditions that last over six months. The Census tracks the following disabilities: ✓ Work disability-Refers to a condition lasting over six months which restricts a person's choice of work and prevents that person from working full-time. ✓ Mobility limitation - Refers to a physical or mental condition lasting over six months that makes it difficult for a person to go outside the home alone.✓ NOW" Self-care limitation - Refers to a physical or mental condition lasting over six months that makes it difficult to take care of one's personal needs. According to the Census,a total of 13,087 persons with disability resided in the unincorporated County areas,representing venom approximately 13%of the population 16 years of age or old. About 54%of these residents face work disability., 19%have mobility/self-care limitations,and the rerrtain. 27%have both work disabilities and mobility/self-care limitations. In 1999, an estimated 66,000 persons (16years and above)Countywide had some form of disability related to work, mobility, or self-care limitations. The Regional Center of the East Bay estimated in 2000 that there were over 3,000 individuals in the County with developmental disabilities. Persons with developmental disabilities may have communication and learning disorders,and may lack basic life skills. In addition.,between 8,,000 and 17,000+mentally disabled persons are estimated to be living in the County(Contra Costa Consortium 2000-2005 Consolidated Plan). The County's mental health system serves approximately 7,200 mentally disabled adults annually. The living arrangement of disabled persons depends on the severity of the disability. Many live at home independently or with other family inembers. To maintainindependent living,disabled persons may need assistance. This can include special housing design features for the disabled, income support for those who are unable to work,and in-home supportive services for persons with medical conditions among others. Services are typically provided by both public and private agencies. AWWft As shown in Table 6-10, 114 licensed community care facilities are located in the unincorporated areas, including 2 small family homes, 12 group homes, 26 adult residential facilities, and 74 elderly residential facilities. The OWMW 6 Extimiely low is defined as below 30%of area median family incorne. Very low is between 30%and 50%of area median family income. 7 Lower-and moderate-income households that spend more than 30%of their incomes on housing costs(including mortgage or am rent,utilities,taxes,and insurance)are typically considered as overpaying for housing,experience a housing cost burden. 6-12 6. Housing Element majority (74) of care facilities are for the elderly, reflecting the special needs of senior residents, especially those with disabilities. Of the 672 beds available in elderly care facilities,54 are for seniors suffering from dementia.8 . Independent Living Resource(111R),an area non-profit organization,provides information and referral,attendant referral,advocacy., housing assistance, and peer counseling services for persons with disabilities. ILR also offers advocacy services, which aim to maintain or increase access to services,benefits,and odw social services and advises clients regarding their rights under Section 504 of the federal Rehabilitation Act of 1972 for disabled individuals. RR's housing referral services assist clients by ;*1;*%r1 a adaptable, of accessible, affordable agpartrr s and houses,information on how to adapt a living environment to a disabled individuals needs,and assistance with obtaining a low income housing subsidy. ILR has offices in Antioch,Concord,and Richmond. Transportation service for paww with disabilities is available through County Connection Link made available by the Central Contra Costa Transit Authority. Under this--- door-to-dom.)dial-a-ride para-transit services are offered to individuals with disabilities. Transportation services are also provided by East and West County Para-transit,WestCat and Tri-Delta Transit Services.

Single-Parent Households Because of their relatively lower hxxmws and higher living expenses,singk1mrent households we more likely to have difficulty finding affordable,decent,and safe housing. These lxx. kls often require special consideration and assis#ance as a result of their greater need for affordable hours*accessible day carel6bildicme,health care,and other st sportive services. Female-headed fiunilies with children are a particularly vuhxrble group because dry nwst balance the needs of their children with work respomibilities. An estimated 3,016 female-headed households with children lived in the unincorporated: areas of the County in 1990, 6%of all households(1990 Census). Countywide,there were a total of 21,215 female-headed households with children,comprising 7%of all households in the County.Within unincorporated areas,approximately 31%of female-headed S to iust arried-couple des with chipupportive families with children lived in poverty in 1990,, 3%of m J-- services for single mothers are available through various non-profit organizations in the County,including the East Bay Perinatal Council,Pregnancy Center of Contra Costa,Mount Diablo Adult Education,and Safe Serenity Home,among others. Battered women with children comprise a sub-group of female-headed households that are especially in need. In Contra Costa County, the largest agency serving battered women is Battered Women's Alternatives, now known as STAND! Against Domestic Violence. STAND! assists over 8,000 battered women in Contra Costa, Solano, and Alarneda counties annually,and offers a variety of services to victim of domestic violence,including a 24-hour crisis line,,a 24-bed emergency shelter,a transitional housing center,legal advocacy,employment assistance,and a batterer's Program. Large Households Large households are defined as those consisting of five or more inerijuets. These households cornnVpnsee a need group, because of the often limited supply of mately affordable housing units in,a community. In order to save for other basic necessities such as food,clothing and medical care,it is common for lower-income large households to reside in smaller units,which 8 Dementia is caused by different illnesses affecting the brain. It may*involve memory loss,and ability to think clearly, to understand words and to recognize people. People with dementia can show personality changes and unusual/distressing behavior. Dementia is rare before the age of 65 and the risk increases with age. 6-13 0". Housing Element frequently results in overcrowding. An estimated 5,069 large households resided in the County unincorporated areas in 1990,28% OWNM (1,430)of which were renter households. Countywide,there were a total of 30,854 large households,of which 31%were renters. The housing needs of large households are typically met through larger units. As of 1990,the unincorporated areas in the County had 27,569 owner-occupied and 3,883 renter-occupied large units(with three or more bedrooms)that could accommodate large households. However,many of these units are single-flinuly homes and are expensive;they are not likely to be occupied by lower-income renter households. Therefore,overcrowding is more prevalent among large renter households. Countywide,51% of large renter households and 19%of large owner households lived in overcrowded conditions in 1990. To address overcrowding,communities can provide motives to facilitate the development of affordable apartrnerrts with three or more bedrooms to meet the needs of large households. Oftentimes,the shortage of large rental units can be alleviated through the provision of affordable owner rJ*housing opportunities,such as condominiums coupled with homeownership assistance and self- help housing(through Habitat for and other sirnilm organizations). Also,Section 8=W assistance provided by the Housing Authority of Contra Costa County(HACCC)can enable large families to rent units they odunvise cannot afford. The HACCC currently manages 447 public housing units for families in the unincorporated areas. With a total of 250 units for families,Bayo Vista in Rodeo is the largest public housing development in the unincorporated areas. Agricultural Workers two^ Agriculture has been an irortannt,but recently declining industry in Contra Costa County. Between 1997 and 1999,the total gross value of agricultural products and crops dropped from $95.2 million to $86.7 million. Approximately 54%of land Countywide is allocated tos m'40 and harvested cropland. (County Department of Agriculture). According to the 1997 Census of Agriculture,587 farms were operating in Contra Costa County,the majority of which were less than 50 acres in size. Agricultural workers we traditionally defined as persons whose primary incomes are earned through permanent or seasonal agricultural labor. Permanent finn laborers work in the fields,processing plants,or support activities on a generally year-round basis. When woddoad increases during harvest periods,the labor force is supplemented by seasonal labor,often supplied by a labor contractor. For some crops,fivrns may employ migrant workers,defined as those whose travel distance to work prevents them from to their primary resideence every evening. Determining the true size of the agricultural labor force is problematic. For the government agencies drat track firm labor do not consistently define (e.g.field laborers versus workers in processing plants),lc*th of employment(e.g.pm,­____t or seasonal),or place of work(e.g.the location of the business or field). According to the 1990 Census, 5,344 persons in Contra Costa County were employed in the fanning, forestry, and fishing occupational category in 1990. Of these persons, 1,529 or 29%were residents in the unincorporated areas. A Statewide study of migrant and seasonal farmworkers completed in 2000 estimated that 2,470 migrant and seasonal farmworkers were working in Contra Costa County(Migrant and Seasonal Farmworker Enumeration Profiles Study-- California, U.S. Department of Health and Human Services, 2000). Based on discussions with various agencies, the County understands that the majority of the fartriworker population in the unincorporated areas consists of resident- saw households requiring permanent affordable housing rather than migratory workers with seasonal housing needs. Fannworkers are generally considered to have special housing needs because of their limited income and the often unstable nature of their employment(i.e.having to move throughout the year from one harvest to the next). While no local survey is available which documents the specific housing needs of farm labor in Contra Costa County,Statewide surveys provide some insight into the demographic characteristics and housing needs of farmworkers. Among the major findings are: ✓ Limited Income-Farmworkers,typically earn very low incomes. According to the Rural Community Assistance Corporation, three-quarters of California's farmworkers earned less than$10,000 a year in 2000. Only one out of seven earned more than$12,500 annually. V Overcrowding-Because of their very low incomes,farmworkers have limited housing options and are often forced to double up to afford rents. A Statewide survey indicates that overcrowding is prevalent and a si cant housing problem among farmworkers(The Parfier Survey,California Institute for Rural Studies,1997). ✓ Substandard Housing Conditions - Many fannworkers live in overcrowded conditions and substandard housing, including informal shacks, illegal garage units, and other structures generally *AM unsuitable for occupancy(The Parlier Survey, 1997). The provision of a equate housing for 6a mmicers and their families is a ns*uW concern is the State. In 1999,the State legislature amended the housing element law to rrraxrdate j'1,'1:1risdic wim address housing for agricultural workers. Under the County's Zoning Code,farm.Labm housing is pwnitted in the agricultural zone districts(A-2,A-3,and A4)subject to a land use permit The County Consortium.Consolidated Plan(2000-2005)indicates that some housing is provided for agricultural workers in County farm er camps,but there is a need for additional housing opportunities for farmworkers and their families. SNOW. To meet the housing needs of farmworkers,the County has provided CDBG and/or HOME fimding for various developments in East County that provide affordable homeownership opportunities for extremely low and very low income households,ince many fi tworker farnilies. These projects include Via de Guadehipe,Najam Estates,Colonia Santa Mar*Marsh Creek Vista,and Arroyo Seco,totaling 241 units. In addition,the County recently approved$1 million in fiscal year 2001/02 HOME Rinds for the 6-14 6. Housing Element Villa Amador project in Brentwood. This project involves the new construction of 91 town home rental units affordable to lower income households. The project sponsor is also applying for State Fmnworker Housing Grant Finds to support the development of the project The County recognizes the imrportarice of providing affordable housing to the fannworker population. The County Agriculture Advisory Task Force has been requested by the Board of Supervisors to develop tions to address the affordable housing needs of farmworkers in Contra Costa. Homeless Persons The 1990 Census documented 47 homeless persons in the unincorporated areas of Contra Costa County and a total of 936 Countywide. Based on current experience, these figures are clearly undercounts. The methodology used in the 1990 Census to count the number of homeless is widely acknowledged as ineffective, thereby resulting in substantial undercounting of the homeless population in many communities,especially larger cities. The Contra Costa Continuum of Care Plan indicates that at least 14,700 people m Contra Costa County experience an episode of homelessness annually, with 4,000 people homeless on any given night. More than three-quarters of them are members of a family,including nearly 7,000 children. On any given night,homeless persons in the County are living on the streets or in temporary accommodations, such as an emergency shelter. Additionally, many others are at risk of becoming homeless,especially very low-income households who are overpaying for housing and struggling to make ends meet. There are three major types of facilities that provide shelter for homeless individuals and families: emergency shelters,transitional housing,and permanent housing.These types of facilities are defined below: ✓ Emergency Shelter-A facility that provides overnight shelter and fulfills a client's basic needs(i.e. food, clothing, medical care) either on-site or through off-site services. The permitted length of stay can vary from one day at a time to three months. There are approximately 490 emergency shelter beds in Contra Costa County, including those reserved for persons with special needs such as the mentally disabled, battered women and their children,recovering substance abusers,and persons with HIV/AIDS. ✓ Transitional Housing-A residence that provides housing for up to two years.Residents of transitional housing are usually connected to supportive services designed to assist the homeless in achieving greater economic independence and a permanent, stable living situation. Services may include substance abuse treatment,mental and physical health care interventions,job training and employment services, individual and group counseling and life skills training. There are approximately 400 transitional housing units in the County. ✓ Permanent Housing-Permanent housing that is affordable in the connnunity or service-enriched permanent housing that is linked with on-going supportive services(on-site or off-sine)and designed to allow fonnerly homeless clients to live at the facility on an indefinite basis. There are approximately 160 permanent supportive housing units in Contra Costa County. Table 6-11 on the following page is a listing of the major housing facilities for the homeless in Contra Costa County. These facilities serve a variety of homeless persons, including battered women and children, mentally and/or physically disabled persons,individuals recovering from substance abuse,and needy families. As a means to help meet the special needs of the hornless,the Contra Costa Crisis Center has establi.sned a 24-Dour homeless hotline that connects homeless individuals and families to resources available in the County. Through the Center,homeless persons are screened for shelters,given emergency motel vouchers,provided free voice mail boxes,and referred to local programs that offer I ansitional .,job training,substance abuse treatment,mental health counseling,ems food,health care,and other services. To more ensively address the issue of hornlessness,the County Health Services Department develops plans and programs to assist the homeless throughout Contra Costa County. Specifically,the Department provides emergency and transitional shelter as well as supportive services designed to enable homeless persons to achieve greater economic independence and a stable living environment The Department coordinates the activities of and provides staffsupport to the Contra Costa Contim m of Care Board (CoC Board),which consists of representatives from local jurisdictions,homeless service providers,advocacy and volunteer groups, the business and faith communities,residents at large,and previously or currently homeless persons. The CoC Board serves in an advisory capacity to the County Board of Supervisors on issues related to homelessness, and participates in the long-range planning and development of strategies to alleviate homelessness m the County. The CoC Board works with the Health Services Department to develop the County's Continuum of Care Plan and annual McKinney Act application,educate the public about homeless issues,and advocate for increased funding for homeless programs. The County Housing Authority also plays an important role in providing shelter to homeless individuals and families. During the 1990s,the Housing Authority acquired and/or rehabilitated major homeless facilities,including the Mountain View transitional housing facility in 1993 and West County Emergency Shelter in 1994. The Housing Authority is currently completing the rehabilitation of the Central County Emergency Shelter. Under the County's Zoning Code, emergency shelters and transitional housing designed to meet the needs of those who are homeless or formerly homeless are permitted in all residential zones subject to a land use permit. In addition, these facilities are allowed in most commercial and industrial districts with a land use permit. (See discussions on the provision of a variety of housing types contained in Section 6.3,Housing Constraints). 6-15 3.Land Use Element (h) Mineral resources quarrying; (i) Oil and gas wells; (j) Pipelines and transmission lines;and (k) Veterinarian offices and kennels.

Southeastern Contra Costa County contains a range of natural and cultural resources which warrant special recognition in the General Plan. Mineral and meteorological resources exist which have the potential to be developed as additional uses within this essentially agricultural area. Multiple uses of the land which assist in its long term protection as an agricultural area are to be encouraged. Policies regarding these specific natural and cultural resources are briefly summarized below. However, a more detailed discussion and additional policies should be referred to in other elements of this General Plan,separated into the following topics: 0 wind turbine developnwnt or wind energy"farms"(policies are found in the Conservation Element); 0 mineral resource areas(policies are found in the Conservation Element); 0 archaeological and wildlife resources(policies are also found in the Conservation Element); 0 Contra Costa Water District reservoir(s) planned in this area (policies are found in the Public Facilities/Services Element); 0 the East Contra Costa County Airport(policies are found in the Transportation and Circulation Element); 0 existing and planned recreation uses in the area(policies are found in the Public Facilities/Services Element); 0 general circulation uses(policies are found in the Transportation/Circulation Element);and 0 Policies and implementation measures regarding the wildlife and archeological resources of the area are included in the Conservation Element. The southeastern portion of the County is blessed with archaeological and wildlife resources which are unique and worthy of long term protection and preservation. While in certain portions of the planning area multiple uses of the land may conflict with the need for environmental protection and enhancement,there are other areas where multiple use may reinforce preservation. As a practical matter,it should be recognized that historically it has been the agriculturalists who have protected the unique environmental resources of the area. Their continued efforts in this regard are critical to the long range preservation of the area's resources. +- 4W-.3-70. The California Energy Resources Conservation and Development Commission has identified the Altamont Pass area, including the south-eastern portion of Contra Costa County,as an area with high wind energy potential. The"Wind Energy Resources"section of the Open Space/Conservation Element contains a map that depicts the generalized boundaries of the wind energy resource area in Southeast County, based on materials developed for the State Energy Commission. The map identifies those areas that experience average wind speeds of at least 15 mph at an altitude of 70 feet above the ground. The same section includes specific policies that govern new wind turbine development in the County. Clusters of wind turbines generate a certain amount of noise which could be a nuisance if new subdivisions or residences are allowed immediately adjacent to the existing turbines or on properties already approved for wind turbines. New residential uses should be discouraged within the wind energy areas.If wind farms become obsolete or are removed in the area, these policies should be reviewed through a subsequent General Plan Amendment. Wind farm uses are to be considered appropriate within the resource area or along the periphery of the wind energy resource area,subject to a careful review of the environmental m4mcts of specific wind farm proposals. A=W3-71-_,....__Within Southeast Contra Costa County there is a geological deposit of dornegine sandstone located just southerly of Camino Diablo and easterly of Vasco Road. This area is further discussed and mapped in the"Mineral Resources"section of the Open Space/Conservation Element. Limited residential or ranchette development of these mineral properties may be appropriate,but residential use shall be identified as secondary to mineral operations and will not be allowed to preclude the full 3-33 3.Land Use Element utilization of identified mineral resources. Any nearby residential use will be permitted conditionally after recognizing the probable expansion of mineral operations and accepting the possible nuisance and inconvenience associated with mineral operations. 3�_�-72._ Public agencies are in the process of acquiring substantial portions of thepA5 area to serve the needs of the growing population of the East Bay.

Each is discussed further in the Circulation Element and the Public Facilities/Services Element,respectively. The general location of the airport is shown on the land use element plan map. As the airport project proceeds, land developments in the area must take into account safety, noise, aviation easements, and preservation of the area's agricultural and biological resources. . btfild.!"a-a'vaqtleros- R The district Board of Directors.bas decided t JL e or eiistiLiv.

The historic significance of the Byron Hot Springs site is acknowledged,the rehavilitation of buildings of historic value at the Byron Hot Springs site and the re-estab i sI -ent of the historic suse of the buildings as a hotel and spa are supported. The rehabilitation of the historic buildings on the Byron Hot Springs site should occur in a manner that is both consistent with other General Plan policies and compatible with the operation of the nearby Byron Airport,as reconmwnded in the ALUC compatibility Plan. Implementation of this policy should occur through a discretionary permit review process. Any proposal for the development of a larger resort complex on the Byron Hot Springs site,which may include the incidental rehabilitation of historic buildings,should be undertaken in the -- context of existing General Plan policies. 3-74,--3-93.. This plan further recognizes that if a reservoir or reservoirs are built, that the Contra Costa Water District or other agencies may be required to construct additional secondary construction and access roads on these lands in order to serve their facility. 3-75= - The Southern Pacific railroad provides rail service through Brentwood and Byron. No change in status is anticipated in this plan amendment. However,the railroad right of way does provide the potential for a recreational trail route and for construction of future pipelines. POLICIES FOR THE BAY POINT AREA T.and Ike 3-76, 3- --The following policies shall guide development in the Bay Point area: (a) Upgrade comiraanity appearance by encouraging development of new uses to replace antiquated developn=ts.

(d) Achieve and maintain a healthy environment for people and wildlife,that sizes health hazards and disruptions caused by the production,storage,transport and disposal of toxic materials. (e) A Redevelopment Plan for the Bay Point area was adopted by the Board of Supervisors in December,1987. All development proposals should be reviewed by,and coordinated with,Redevelopment Agency staff to ensure compatibility with the Redevelopment Plan. Additionally, involvement with the redevelopment process will allow the County to coordinate concurrent development proposals and to possibly facilitate the construction of public irr�roven=ts that will further the goals of the Redevelopment Plan.

Existing drainage facilities are antiquated and inadequate. Modifications to existing road design and access points would be desirable to handle greater traffic loads. Given these parameters, an incremental uncoordinated approach to development would probably fail to safeguard community interests. Therefore, this plan supports the assembly of land designated for multiple family residential uses in sufficient acreages to make feasible the provision of a quality residential environment and adequate infrastructure to handle drainage and traffic concerns. Those projects that meet these objectives will be eligible for the maximum housing units within the range of the applicable density category. -3-7 -3-98.---The following development standards shall be applied to projects proposed in the Willow Pass Road Mixed Use Corridor MI 14): (a) access to parcels along Willow Pass Road should be ed and should be from secondary roads whenever feasible; (b) development of shared access with uses on abutting properties should be considered at the time of project review; (c) the assembly and consolidated development of frontage parcels is encouraged by this designation; (d) control on the placement design, number, and size of signs should occur during project review and should be adequate to inform the community of the farm's identity without being visually disruptive;and (e) the County shall consider the adoption of a streetscape plan for Willow Pass Road including, if appropriate, revision to existing precise alignment plans.

Particularly vulnerable areas should be avoided. Slopes over 25%are generally not suited for conventional cut and fill pad development; 3-45 3.Land Use Element (b) Where flood control and drainage works are required along natural water courses, special consideration should be given to using innovative means of retaining the natural appearance of the waterway,and preserve the vegetation and wildlife it supports; (c) Conservation of the scenic beauty of the planning area requires restoration of natural contours and vegetation after grading and other land disturbances, and the design of public and private projects to minimize damages to significant trees and other visual landmarks; (d) Public facilities for outdoor recreation should remain an important land utilization objective in the community, to promote high visual quality, air quality maintenance, and to enhance outdoor recreation opportunities of all residents;and (e) Extreme topographic modification,such as filling in canyons or removing hilltops is to be avoided. Clustering and planned unit development approaches to development are encouraged. All future development, whether large or small scale, should be based on locating safe and suitable sites for buildings, roads and driveways. Edwards Canyon is very sensitive to erosion and siltation problems and should be given special protection. Scenic Waterways are watercourses which receive use by fishing and recreational boat traffic and traverse areas of significant scenic quality. The scenic waterway designation applies to the waterway and its shoreline. -"1-!69.The shoreline and hills along Carquinez uinez Strait between Crockett and Martinez constitute one of q the few undeveloped coastal areas in the East Bay. The scenic beauty of the area enhances, and is complemented by, the historic town of Port Costa. Preservation of this resource through the establishment of a recreation area is encouraged by this plan. _3-.1F .--Crockett has an abundance of charming Victorian buildings. The special scenic and historic qualities of the town should be reflected in a sensitive approach to rehabilitation of these buildings. The structures listed below have been identified as local historic places, reflecting their historic and cultural importance to the community. It is a policy of this plan that the following places should be protected and their historic qualities should be preserved and enhanced: - (a) the American Legion Hall at Pomona and Alexander Streets; (b) the Rolph Park Monument at Pomona Street and Rolph Park Drive; (c) the Railroad depot on Loring Avenue; (d) the Crockett Auditorium on Pomona Avenue; (e) the Episcopal Church on Pomona Avenue; (f) the C&H Company House and Guest house in Crolona Heights; (g) the Crockett Library on Loring Avenue; (h) the Edwards Homestead;and ._ (i) the Loring Road Victorians. - 3-311.17 --Devel ment of the Pointe Crockett General Plan Amendment is intended to support up to 100 units,while the exact placement of housing units and open space areas will be further defined through the site process.

Open space tions for this area reinforce the Countywide goal of agricultural preservation for continued Pace desi� agricultural productivity. The existing pattern in the open space area of relatively large parcels under consolidated ownership is necessary to successful range practices and will be maintained under this plan.The scenic value of the Franklin Canyon area has been asserted by the Rodeo community and is reflected in the -" scenic route designated for Highway 4 in the scenic routes section of the Transportation and Circulation Element.The hills and ridges along this route are the primary source of the corridor's visual quality and every effort should be made to protect its scenic characteristics. - —Because of noise related impacts, both from transportation sources and from industry, acoustical B P studies will be required for major new developments and multiple family projects in the Planning Area even those extending beyond the 60 CNEL Noise Contours. -- POLICIES FOR THE EL SOBRANTE AREA In cooperation with the Ci of Richmond, develop a Specific Plan for the San Pablo Dam Road - 3= p City . commercial corridor to provide detailed plans and implementation measures to increase parking for shoppers and increase roadway capacity for through traffic. 96.

For all industrial categories,the Plan should accommodate and guide the growth and development of industry. With growth and development there needs to be a recognition of environmental, social and economic values which will work to mixa* * e land use conflicts, to establish a reasonably pleasing setting and to protect natural resources that are irreplaceable. Through appropriate regulatory mechanisms (e.g., zoning ordinance,nuisance ordinance,etc.)provide for the following: 0 Require a setback from San Pablo and Wildcat Creeks for new structures. The size of the setback will be developed through site development review in conjunction with responsible agencies (e.g., Department of Fish and Game, Flood Control District). Lands within these setback areas shall reinforce the habitat values and/or trail setting of the adjacent flood control project for these creeks. o Require setbacks within shoreline areas to protect wetlands designated by State or Federal regulatory agencies and to provide public access as appropriate. The size of the setback or mitigation will be developed in conjunction with all affected agencies. 349 3.Land Use Element o Require health risks assessments and, where appropriate, provide necessary buffers for all new applications handling substantial amounts of hazardous materials. o Achieve an upgrading of the visual appearance and unity of the area through architectural and -- landscape requirements and utility undergrounding. o Require special geotechnical studies and construction techniques in areas of potential seismic or geological hazards (e.g., Alquist-Priolo Special Study Zone, high liquefaction, and reclaimed wetland areas). o Use established standards to limit activities that may endanger human health and can cause damage to the environment. o Use established standards to limit activities which may be objectionable such as odors, fumes or other emissions so they will be contained within the property boundaries. o Require projects adjacent to parks or recreational corridors to minimize impacts on the recreational values of those facilities. o Require a shadow analysis for projects adjacent to commercial nurseries and protect the solar access of affected properties. o Require archaeology reconnaissance surveys for all projects within an archaeological sensitivity area. When cultural resources are located within a project, measures to deal with the historic --� resource shall be recommended by a qualified archeologist. o Require all uses to comply with the regulations of the Bay Area Air Quality Management District,the Regional Water Quality Control Board, the San Francisco Bay Conservation and Development -- Commission,the State and County health departments,and any other regulatory agencies which exist or may be established to ensure environmental quality in the San Francisco Bay Region. o Screen all outside storage/maintenance areas from public streets. a .1.--- LIGHT INDUSTRY Amend the "Light Industry" land use category of the General Plan Land Use Element for North Richmond to read as follows: Industrial activities in this category are established in areas where development is carefully controlled to ensure compatibility between the industrial operations and other activities and the -- character of the district,community and environment in which they are located. The appearance of each site,building or industrial operation,and each industrial district as a whole,should establish a reasonably pleasing and harmonious setting. Types of uses within this category can range from research, engineering, product development and testing,and sales development to light manufacturing,warehousing,distribution centers,and commercial nurseries. Support retail/service uses may also be found in this category. In addition to the policies and factors established to guide development in all commercial and industrial areas, the following policies and factors are established to guide the development of Special Industrial areas: -- (1) "Apply special zoning designations or planned unit districts to provide use limitations,in cases where uses need to be limited to protect the character of an area,"in all cases where. (2) Limit activities which may result in noise, glare or vibrations extending beyond the property boundary." 5h HEAVY INDUSTRY snow Amend the "Heavy Industry" land use category of the County General Plan Land Use Element for North Richmond to read as follows: "Industry activities in this category are traditionally larger scale and include very little or no office -- space. Sufficient visual open space and/or landscaped screening between industrial operations and adjacent residential or recreational activities shall be required as needed." 3-50 3.Land Use Element This category accommodates a wide variety of activities including,but not limited to,oil refining, contractors'storage yards,warel"isess and sbops. For the North Richmond area,this category also nurseries. Support retail/service uses may also be found in this category. In addition to the policies and factors established to guide developtrient in all comms and irYdustrial areas,the following policies and factors are established to the development of General areas: 0 Encourage commercial nurseries to remain in the area. 0 Require projects involving auto dismantling activities to be enclosed and prohibit outside storage of vehicles. 0 Limit activities which may result in noise, clare or vibrations beyond the designated industrial areas. 0 Make a finding that new residential uses within this designation are incompatible. -3-174, —3T--22-10. 'IMPLEMENTATION The City of Richmond and the County shall undertake a rezoning study of the area to minLy the zoning in conformance with their respective General Plans. All new permits with conditions of approval shall be rnonitored,by the County or City. Additionally,the City of Richmond and the County shall undertake amore vigorous zoning investigation and enforcementprog warn. The County and City shall require verification that all appropriate State and Federal or regional permits are granted before building pem-iits are issued for the projects. Project applicants shall provide a site history for uses that have previously been on the property as part of any permitLy application process. As appropriate,soils analysis for toxic wastes dull be required for permit applications. A Redevelopment Plan for the North Riclunorid area was adopted by the Board of Supervisors in July 1987. All development proposals should be reviewed by,and coordinated with,Redevelopment Agency staff to ensure compatibility with the Redevelopment Plan. Additionally, involvement with the redevelopment process will allow the County to coordinate concurrent development proposals and to possibly facilitate the construction of public improvements that will ftirther the goals of the Redevelopment Plan. 3-176, Lands which were the site of the West Contra Costa Sanitary Laing ownership and which are designated as Open Space,will continue to allow solid waste facilities on the proms as an interim use of the land. 3-]77. -.-rMZ-rU—- "The West County Integrated Resource Recovery Facility site, circumscribed by Central Street, P-01-- Brookside Drive, Third Street and the Wildcat Creek, is recognized as a non-di 'L nsal facihtyC14.I.-*,NP%;-%-. concern for file" 11--tIrLite-mentation of the eomity,s sofid waste nmnuagenmnt systemin-the.-countVwide Int2rated w Ste Management Plan." 3--2 t 4.

POLICIES FOR ESTABLISHMENT OF COUNTY HOMELESS SHELTERS 3.194, 3TWAZ V-65 4 1 Background information on homelessness is also discussed in Section 6.6 of Chapter 6, the Housing Element. Beginning on Page 6-61 of the Housing Element of this general plan,and specifically in Table 6-15 on page 6-62, non-county homeless shelters are discussed. The Housing Element discussion does not apply to County homeless shelters. The purpose of the following policies is to designate where County homeless shelters may be established and under what circumstances. Other policies that address homelessness are contained in the Public Facilities/Services Element. 71-266. ounty homeless shelters may be established in all general plan land use designations (including residential, commercial and industrial, mixed use areas, and other uses), except for Congregate Care/Senior Housing,Landfill,and all Open Space(including Agricultural Lands,parks and Recreation,Agricultural Core, WOO Delta Recreation and Resources, Water, and Watershed) designations. County homeless shelters may be established within areas that lie in incorporated or unincorporated areas. 3-186, 3-0`57 -A County homeless shelter may be established as set forth above, provided that the Board of Supervisors is satisfied that the shelter: (a) has undergone applicable environmental review; (b) will famish residents with sleeping quarters, food, and access to bathroom facilities and trauportation services if necessary or advisable while they are housed at the shelter; (c) will include appropriate and adequate security measures and on-site supervision; (d) will provide a procedure for the receipt and consideration of neighbors'concerns; (e) will benefit the health,safety and welfare of shelter residents;and (f) will not prevent the implementation of General Plan land uses in the vicinity. 3,9 POLICIES FOR SPECIAL CONCERN AREAS Three areas have been designated Special Concern Areas in view of their key locational qualities.

GROWTH MANAGEMENT PROGRAM 4.1 INTRODUCTION The purpose of this Element is to establish policies and standards for traffic levels of service and standards for fire, police,parks,sanitary facilities,water and flood control to ensure generally that public facilities consistent with adopted standards areprovided By including this Element in the adoption of the General Plan,the County intends to establish a long range program which will match the demand for public facilities to serve new development with plans,capital improvement prograrns and development impact mitigation programs. The intent is to ensure that growth takes place in a manner that will ensure protection of the health,safety and welfare of both existing and future residents of Contra Costa County. The responsible management of growth in the County is key to preserving the quality of life for current and future County residents. This Growth Management Element is the culmination of a process which was created by the Mayors'Conference and the County Board of Supervisors. The Contra Costa Transportation Partnership Cbmmission was established as a Transportation Authority under State law(PUC Section 180000)to provide a forum for transportation issues in the County and to propose ways to =em nage traffic congestion. 4:he r,,,�♦amis By a�rovfi Measure C-1988,the voters established�the Transportation Authority • law tA dal4alnm ga CnwatAXAA�4- gwnoAa�efl . , ` ' ' ' '- added one-half cent to the County sales tax for the next?U ,. , JL . Y�2-1*s to be used for transportation funding=and gave the Tran tion Authority the charge to uimleulent a Gt owth Manawement PYo gun. That pro<grain requires the Coim!y and each city to develop a Groyab Mauagemeiit Element as pait of its General. Plan in order to be eli Bible to receive local street maintenance and improvement funds oder-gene��lted b�• Measure C-.1988., - . This Growth Management Element complies with the model element developed by the Transportation Authority and includes the sections required by Measure C-1988 to be part of this Growth Management Element. These sections (1)adopt traffic levels of service standards(LOS)keyed to types of land use,and(2)adopt performance standards maintained through capital projects for fire, police, parks, sanitary facilities, water and flood control. The Transportation Authority fi.Ay "e rr~1 recognizes that facilities standards,as are discussed in this Element,establish performance standards to be applied in the County's development review process. In addition to adopting this Growth Management Element as part of the General Plan under Measure C-1988,the voters of the County,in Measure C-1990,reaffirmed that growth management should be an integral part of this General Plan. This Element is also adopted pursuant to the authority granted to local jurisdictions by Section 65303 of the Government Code of the State of California,which states: "The General Plan may include any other elements or address any other subjects which,in the judgement of the legislative body,relates to the physical development of the county or city." 4.2 RELATIONSHIP TO OTHER GENERAL PLAN ELEMENTS As indicated in Section 3,Land Use Element,the Growth Management Element works closely in conjunction with the Land Use Element to ensure that development proceeds in a manner which will not negatively affect facility and traffic service standards for existing land uses. In this regard,it should be noted that developments which cannot satisfythe requiredbythese standards should not be approved. By utilizing this Growth Management Element to responsibly manage new developmentthe County will ensure that new development projects will bear their share of the adverse burdens and impacts they impose on public facilities and servicers. As a result,the Growth Management Element must be carefully considered together with Land Use and other elements of this General Plan when assessing General Plan consistency. The timing of the potential physical development contemplated in the Land Use Element will in part be A ' ed by the ability of developers to satisfy the policies and standards 4-1 described in this Growth Management Element The Urban Limit Line(ULL)and the 65/35 Land Preservation Standard also work together with the Growth Management Element to ensure that growth occurs in a responsible n-mmer and sh*es balances between many con4xting values and interests. 41000, In addition, this Growth Management Element contains implementing programs which encourage new development to feeilitate the attainment e -promote the goals and objectives of the Conservation Element; the Public Facilities and Services Element;and the Housing Element. Moreover,by establishing an interjurisdictional land, supply and develgpment monitoring program, the Growth Management Element coordinates the WOO* implementation of the County General Plan with those of the 199 cities in the County. To carry out the goals and objectives of the Land Use and Circulation Elements of the Plan,new development must "Now demonstrate that the level of service standards of the Growth Management Element will be met Only in this way will the negative effects of such growth be avoided. While it is anticipated that new growth will be able to mitigate its potential facts through development fees and other exactions,it is possible that the timing of project approvals may be affected by the inability of individual developments to carry its appropriate cost of full service increments needed to allow further growth in a given area ofthe County. Thus,the improvements needed to implementthe CircWation and Public Facilities and Services Elements of the Plan will in part be directly tied to,and dependent upon,the implementation of the Growth Management Element. Similarly,implementation ofthe Land Use Element will only proceed when it can be dernonstraited,that the growth Noma* TrMM standards can be met by new development. Policies relating to this"Pay as you Grow"philosophy underpinning the Growth Management Element can be found in MON* the Transportation and Circulation Element,Overall Transportation/Circulation Goals 5-E and 5-F,and in the Overall Transportation/Circulation Policies 5-1 through 5-4. Related Land Use Element Goals 3-F and 3-H and Land Use Policies 3-5 through 3-10 are also part of the policy framework which underlies the Growth Management Element,and are integrally related to it. In a similar fashion, each of the required growth management performance standards included in this Element is also included in the Public Facilities and Services Element under the applicable goals and policies listed for sewers,water,police,fire,parks and flood control. 4.3 TRAFFIC SERVICE STANDARDS AND FACILITIES STANDARDS The basic unit ofmeasuziernent ofperfommnce ofan intersection or roadway segrnent is called a Level ofService(LOS).LOS is a measure ofthe ratio ofthe volume to capacity of a roadway or Mtersection and is as a letter A through F. In general LOS A describes fire flowing conditions,and F describes very congested conditions,with long delays. Routes of Regional Significance are those roadways which carry sivolutins of through traffic,which neither begins nor ends within the affected jurisdiction. They generally include Interstate Freeways and State Highways,as well as local roads which,due to their tow location between job and housing centers,carry signiflcant volumes of intra-county trips. All other roadways iii dffte pi are refeff ed to in the Growth Management Element as Basic Routes. &asic routes,and their sigr>i�li��rd intersections,are those to which LOS are applied in Imul6- proposed projects maybe 1 The methodology used in de imm if projects exceed allowable LOS standards is the 212 N&e.00111KOd 1AVidla 6esmediod established by the Contra.Cosw Tram pott-ifion Autliori!y fii its Technical Proceduits. At present,most Basic Routes in the unincorporated area operate at or better than the LOS Standards specified in the Growth Management Element. Tvlan3,Routes of Regional Significance are getais below these standards,however, reflecting the fact that the trips are not dependent upon land uses in unincorporated Contra Costa County,but are cumulative with traffic generated by land uses located outside ofthe unincorporated areas. Public Protection Facility standards contained in this plan are based upon the 1990 facilities to unincorporated population ratio. In the area of parks,for example,the current unincorporated population to park acreage yields a ratio of less than I acre per 1,000 persons. While certain developed areas of the County experience flooding in the event of the 100-year flood,the County Ordinance Code collect-and-convey requirements are applied to all new developments. Water and sewer services are generally adequate for existing development. low* For the purposes of establishing a Public Protection Facility standard,several factors must be considered. Firstly,the unincorporated community of Kensington has established a Community Services District which provides the full range of police services in the area,and the Sheriff does not service this area. Secondly,the California Highway Patrol is responsible for enforcement of the Vehicle Code on highways and County roads throughout the unincorporated area. Thirdly,certain economies of scale enable the Sheriffto provide patrol and investigation services in physical facilities 4-2 substantially smaller than a comparable series of cities would require,due to centralized administrative services,crime lab facilities and other similar functions which numerous cities would duplicate in each location. According to the Department,very little time is spent by deputies in the stations;nearly all is spent in the vehicles on patrol;no clericals are housed in the stations. In addition,the Sheriff also provides coroner services,incarceration and criminalistics services. For these reasons,direct comparisons between County facilities standards and standards that maybe adopted by cities in the County are not advised,since such comparisons would be highly misleading. The computation of a Sheriff facility standard in this General Plan includes only patrol and investigation services, adjusted for a marginal increase in centralized administrative services. As of January, 1991,the County provides approximately 155 square feet of floor area per thousand population in six locations throughout the County.—Iii 1997.it became evident that the Sherift"s Office needed to include support facilities necessary to conduct atrol. and lnyesti�ra�tio_.n.whicll are now included in the calculation of new square ..foo e. It should be noted that implementation of the goals of this Plan's various elements depends not only upon the County's administration of the Growth Management Program described below,but upon the interplay of several levels of government. Federal and State funding for improvements to Basic Routes will be required to attain and maintain traffic levels of service at designated levels. Finally,the County,the 1,9-9 cities,the Contra Costa Transportation Authority,the Bay Area Rapid Transit District,and the California Department of Transportation will all have to work cooperatively in order to mitigate the negative impacts of growth upon the regional transportation system to achieve the levels of population,housing and jobs anticipated by this Plan. 4.4 GOALS,POLICIES AND IMPLEMENTATION MEASURES GOALS 4-A. To provide for the levels of growth and development depicted in the Land Use Element,while preserving and extending the quality of life through the provision of public facilities and ensuring traffic levels of services necessary to protect the public health,safety and welfare. 4-B. To establish a cooperative inter urisdictional growth monitoring and decision making process in which each jurisdiction can share in the beneficial aspects of new growth,and avoid its potential negative effects. POLICIES 4-1. New development shall not be approved in unincorporated areas unless the applicant can provide the infrastructure which meets the traffic level of service and performance standards outlined in Policy 4-3,or a funding mechanism has been established which will provide the infrastructure to meet the standards or as is stated in other portions of this Growth Management Element. 4-2. If it cannot be demonstrated prior to project approval that levels of service will be met per Policy 4-1, development will be temporarily deferred until the standards can be met or assured. Projects which do not,or will not,meet the standards shall be scheduled for hearing before the appropriate hearing body with a staff recommendation for denial,on the grounds that the project is inconsistent with the goals,policies, and objectives of the Growth Management Element of the County General Plan. 4-3. Table 4-1 shows the performance standards which shall apply to development projects. In the event that a signalized intersection on a Basic Route exceeds the applicable level of service standard,the County may approve projects if the County can establish appropriate mitigation measures,or determine that the intersection or portion of roadway is subject to a finding of special circumstances,or is a Route of Regional Significance, consistent with those findings and/or action plans adopted by the Contra Costa Transportation Authority pursuant to Measure C-1988. Mitigation measures specified in the action plans shall be applied to all projects which would create significant impacts on such regional routes,as defined by the Authority in consultation with local agencies and as permitted by law. For the purpose of reporting to the Contra Costa Transportation Authority in compliance with the Growth Management Program,a list of intersections that will be reported on Basic Routes will be prepared and maintained by the Community Development Department. 4-3 4-4. The County institute an ongoing growth management program process,as generally depicted in Figure 4-1. *.low 4-5. For the purpose of applying the Traffic Level of Service standards consistent with Measure C--1988 only, unincorporated areas subject to the growth xnanagejnent standards of this Element shall be characterized as Central Business District Urban,Suburban,Semi-rural and Rural as depicted in Figure 4-2. Pow% 4-6. Conformity with the growth management standards will be analyzed for all development projects such as, subdivision maps,or land use permits. A general plan amendment is a long range planning tool and is not to be considered a development project or a project approval under the growth management program. Traffic LOS Standards will be considered to be met if: 0 measurement of actual conditions at the intersection indicates that operations are equivalent to or better than those specified in the standard;or 0 the County has included projects in its adopted capital improvements program which, when own* constructed,will result in operations equal to or better than the standard. TABLE 4-1 GROWTH MANAGEMENT PERFORMANCE STANDARDS Traffic Levels of Service Keyed to Land Use Type Rural Areas: Peak Hour Level of Service of low C (Volume/Capacity Ratio=.70-.74) Semi-Rural Areas: Peak Hour Level of Service of high C (Volume/Capacity Ratio=.74-.79) Suburban Areas: Peak Hour Level of Service of low D (Volume/Capacity Ratio=.80-.84) Urban Areas: Peak Hour Level of Service of high D (Volume/Capacity Ratio=.85-.89) Central Business Peak Hour Level of Service of low E Districts(CBD): (Volume/Capacity Ratio=.90-.94) Note: These terms are used solely with reference to the Growth Management Element performance standards. Water The County,pursuant to its police power and as the proper governmental entity responsible for directly regulating land use density or intensity,property development and the subdivision of property within the unincorporated areas of the County, shall require new development to demonstrate that adequate water quantity and quality can be provided. At the project approval stage,(subdivision map,land use permit,etc.),the County may consult with the appropriate water agency. The County,based on information furnished or available to it from consultations with the appropriate water agency,the applicant or other sources,should determine whether(1)capacity exists within the water system if a development project is built within a set period of time,or(2)capacity will be provided by a ftmded program or other mechanism. Project approvals conditioned on(1)or(2)above,will lapse according to their terms if not satisfied by verification that capacity exists to serve the specific project("will serve letters"), actual hook-ups or comparable evidence of adequate water quantity and quality availability. 4-4 moo i 1 ■ •O Lm cc LO >, L Low LO 0 — N O o V _ �-, 0 C 0 as cc _ 4� •i = _° ` m � •� � aLD o0 '� c� Ida Co CM 0 0 0 _ _O _ _ _ V = �• V. 0 •_ O .� _ 0._ = o *a w v a 0 E c i ` >% O Cc !Q cc 0 0 0. a d- .0 C — a. cccis ca m L L L A o c� o a Page 0 Two0 0 � � � w 4-5 l J t ' is ,r i i ENO Pon lob Y a f-" sit, r K .•' 1 1 -•+ �� tf x tii�• '+1�'s t1-6.r'■«'t' f�i U3 #• ,L'`1` {:},•t . x�i3+y l D t as L y iz t•a'x,14}i,isi,r;'�Rwt'!1t 1 i i.•t4 t ;inning wig s K� E ! •" 1•. •. !.1:•`.i.. •.•. 11.■.•'t..• � M 1/11•Rfw •k • t"•ii t t1 11� {'. r•_• �- jf Y$ Q'a' 2 r Fr J ►�,r wt 't•'� •t' +' `'+�' 1.•`«'■ �' .RG r7 ow" 'r }K Q i T' ,}•t' ;1• ,t tt"i t f {{ ,1.. s a)'► '" •�eqw iri r••t•t �. ,...t,i r FIs. ��`.-•�4 a/i�•w}tr a m.

At the project approval stage,(subdivision map,land use permit,etc.),the County may consult with the appropriate sewer agency. The County,based on information furnished or available to it from consultations with the appropriate sewer agency,the applicant or other sources,should determine whether(1)capacity exists within the sewer system if the development project is built within a set period of time,or(2)capacity will be provided by a funded program or other mechanism. Project approvals conditioned on(1)or(2)above,will lapse according to their terms if not satisfied by verification that capacity exists to serve the specific project("will serve letters"),actual hook- ups or comparable evidence of adequate sewage collection and wastewater treatment capacity availability. Fire Protection Fire stations shall be located within one and one-half miles of developments in urban, suburban and central business district areas. Automatic fire sprinkler systems may be used to satisfy this standard. Public Protection A Sheriff facility standard of 155 square feet of station area and support facilities per 1,000 population shall be maintained within the unincorporated area of the County. Parks and Recreation Neighborhood parks: 3 acres required per 1,000 population. Flood Control and Drainage Require major new development to finance the full costs of drainage improvements necessary to accommodate peak flows due to the project. Limit development within the 100 year flood plain until a flood management plan has been adopted and implementation is assured. For mainland areas along rivers and bays, it must be demonstrated that adequate protection exists through levee protection or change of elevation prior to development. Development shall not be allowed in flood prone areas designated by the Federal Emergency Management Agency until a risk assessment and other technical studies have been performed. IMPLEMENTATION MEASURES 4-a. Incorporate the performance standards outlined in Policy 4-3 into the review of development projects. 4-b. Work cooperatively with the 1,99 cities and the Contra CostaW n�Transportation Authority through each of the SubRegional Transportation P.lau1Committees to define action plans for mitigating the impacts of development on Routes of Regional Significance. 4-c. Require traffic impact analysis for any project which is estimated to generate 100 or more AM or PM peak-hour trips based upon the trip generation rates as presented in the Institute of Traffic Engineers(ITE) Trip Generation,+6th edition, 19 97,o.r the.most cinTent published edition. 4-d. Require that during the review of development proposals, the traffic impact analysis shall determine whether a project could cause a signalized intersection or freeway ramp to exceed the applicable standard and shall identify mitigations/fees such that the intersection or ramp will operate in conformance with applicable standards. Development proposals shall be required to comply with conditions of approval detailing identified mitigation measures and/or fees. In no event shall Local Road Improvement and Maintenance Funds replace development mitigation fee requirements,pursuant to Measure C-88. 4-7 •....,, 4-e. Establish through application to the Contra Costa Transportation Authority,and in conjunction with the regional committees,a list of Routes of Regional Significance and Intersections proposed for Findings of Special Circumstances.

The County shall develop and carry out a growth management/monitoring program as generally indicated in Figure 4-1,as follows: (a) a land supply and development monitoring process; (b) periodic review of performance standards and monitoring of infrastructure constraints; (c) interagency coordination and decision-making to provide information for the first two-tasks and successfully implement the overall growth management program; (d) a i obs/housing performance evaluation to determine their relative balance within each sub-region .,.., of the County;and (e) growth management determinations,a process which identifies growth areas capable and incapable of Saba meeting performance standards,and directs resources to overcoming any constraints. These components are described in detail below. Adoption of Performance Standards The first step in the growth management program process is completed upon the adoption ofe standards for public facilities and services in this Growth agement Elerrient. Figure 4-1 shows the flow chart ofthe growthmanageme 1 process. Land Sumly/Development Monitoring Analysis The second step in the growth management process,an analysis of land supply and development monitoring,will con m=ce at the beginning of each calendar year. Annual status reports on the implementation of the General Plan and its Growth Management pfogmmElenient will be submitted to the Board of Supervisors and City Councils in June. This status report will fulfill the requirements ofGovernnmt Code 65400(b)in the State planning and zoning laws,which requires that every " city and county must prepare an annual report to the City Council or Board of Supervisors and the State which summarizes the status of the General Plan and the progress that has been made in its implementation.The subsequent steps in the process, commencing with the perf�ce standards evaluation,will occur on a five-year cycle. The land supply and development monitoring process is a two-part component designed as the basis for the periodic re-examination of lands available in the County for urban development. The availability of developable lands is then contrasted against the actual rate of growth which has been measured over the most recent period. In essence,this component is a land supply and demand tracking process. This process is designed to work in tandem with the other four components (performance standards/infrastructure constraints analysis, inter urisdictional coordination, jobs/housing balance analysis, and growth management determinations) in order to obtain an updated,working perspective of the current capacity of the County to accommodate growth. The land supply 1 and development monitoring process is prepared in an objective fashion by staff, using a set mo" methodologydefined and agreed to by the jurisdictions involved(the County,the 1,99 cities,the Local Agency , gr Formation Commission(LAFCO)and the individual service providers). The re-examination of the land supply (initially set by the General Plan Review Program) will occur on an annual basis, in concert with the State -� Population Certification program which is already conducted l.?Y.J�,1 the County and each city planning department. . ' '. a .. eal ndnr .c r.r• Using a standard format and methodology should provide a high degree of confidence in the process and the established annual schedule should alert the development interests,city agencies,and special districts as to when their contribution will be critical. At the beginning of each annual cycle,formal notification will be given to each of the cities informing them that the land supply and development monitoring process is being initiated and requesting their active participation and cooperation. 4-12 "x' 63 X C—fiql wk X Au 4 aiu--ulm 41'-AI:14 The Land Use Information System(LUIS),developed in 1987,%�-.Y 'W-'%..-"I A. 1,"a&1-6'%.'A,1..V F.&%"4 AAAJ MAZAA AWA amaiid the more recent Geo c Inf ste provides the foundation for tracking Geaei.A- Plan RR-Nieyv..A%.fb ormation Sy * overall land supply,land absorption,and changing land uses in the County. The specific questions that must be answered during this process with the use of the updated LUIS data system are: 0 how many acres of vacant land in the County,specified by land use type,are identified as available for development.? 0 what changes have occurred in these numbers since the previous evaluation? 0 how many acres of underutilized or previously developed land are available for redevelopment? 0 how many acres of land County-wide have been identified as unavailable for development based upon environmental,health and safety,public resource,or other conditions?The County Community Development Department staffwill prepare a report which examines the absorption rate(i.e.approved development projects) and the General Plan Amendment requests that have been received. The report on the status of development areas will rely upon residential and commercial/industrial building permit and other project approval information from the cities. This permit approval and General Plan Amendment application information will then be compared to the expected rate of residential and job growth projected for the jurisdiction over the planning period by the respective General Plans. The annual report will be forwarded to decision-making bodies for use in reviewing fin-ther General Plan Amendments which would alter the land supply component. Performance Standards Evaluation and Infrastructure Constraints Analysis While the second component of the growth program(land supply and development monitoring)will be prepared on an annual basis,the final four components will generally be performed only once every five years. Although these final four components of the Growth Management Program will be comprehensively and formally evaluated every five years,circumstances may necessitate evaluating and modifying the standards during the annual review of the land supply and development component of this Growth Management Program. If circumstances so necessitate,the Board of Supervisors should consider all information before it including the Land Supply/Development Monitoring Analysis,fiscal constraints,and other information obtained through consultation with the s0llt 43L 3&1&ty-Contm Costa Transportation Authority, before modifying the standards. The data and analysis generated in the annual land supply and development monitoring reports will be aggregated for use in the tasks outlined in the following processes. The intent of this third component of the growth management program,performance and infrastructure capacity evaluation,is to re-examine minimum allowable performance standards for development projects set in the General Plan, and to determine the remaining available capacities of certain infi-astructure facilities. The growth management program for the Contra Costa County General Plan mandates the establishment of infrastructure performance standards for several different services or facilities, including circulation (traffic), sanitary sewage,flood control and drainage,water supply,police and fire protection and emergency services,and parks and recreation. These standards and policies attempt to define a quality of life by setting benchmark indicators of the minimum levels of service required for specific urban services. Every five years the- e standards would be reviewed by staff and the service providers by e�ining prior experience and ability to serve. In addition,service districts may be provided an opportunity to explain why certain standards are not being met and to explore measures to be taken to alleviate the situation. This information would then be used to evaluate whether the standards for the current review period were appropriate. The second major task to be completed during this phase of the growth management program is an evaluation of the remaining infrastructure capacity in various areas of the County. Part of this evaluation will determine where and why certain existing urbanized areas are not being adequately served. The assumption is that adequate infrastructure capacities can be engineered and built to serve virtually any amount and location of urban growth within the ULL,but that opportunities exist to plan for cost-effective and efficient growth in areas particularly within the ULL,where underutilized infrastructure capacities already exist or where the extension of services is relatively unconstrained compared to other areas. 4-13 The basic data requirements of this portion of the process include: 0 a determination of the remaining capacity for each facility or service provider based upon the defined performance standards,and identification of the geographic areas that could be served by the capacity; 0 an itemization of funded infrastructure improvement projects, their location and expected date of completion,and the service area or population they are designed to serve; 0 identification of urbanized areas with inadequate service,as defined by the adopted performance standards; 0 an itemization of the major capital improvements not now funded but needed to bring existing areas into compliance with the performance standards; 0 itemization of major capital improvements necessary to serve anticipated future development at the adopted service level,and the cost of these improvements; 0 identification of major physical,economic and/or environmental constraints to the provision of service or facilities in a given area;and 0 identification of possible sources of funding for the improvements. The object of the data gathering is to illustrate where future growth can and cannot occur without major investment n new or improved infrastructure systems,and to identify the level and source of financing required. Additionally, the exercise will allow the preparation of estimates of future required capacity based upon the performance standards. One outcome of this process will be to provide with up-to-date *information concerning where future Soaft growth is expected to occur,thus assisting in capital facilities planning efforts. To ensure that high density"leapfrog!'growth does not occur,as a matter of policy,this growth management program **Now mandates that new urban and central business district levels of development shall not be approved unless the development is within the ULL and near existing or committed urban or central business district levels of development. Jobs/Housine Performance Evaluation The purpose of this step is to provide a basis for assessing the jobs/housing balance within each section of the County for the current five year review cycle,to assist the jurisdictions in the sub-regions in determining preferred locations for residential and employment growth,and to assist in focusing the direction of implementation programs. The jobsthousing balance evaluation is based upon the County's Land Use Information System data base,augmented by the infon-nation provided in the development monitoring evaluation. The evaluation considers growth in housing units and employment and housing and employment availability,relative affordability and commute patterns,and to the extent that the data are available,price of the units and wage levels of the jobs added. The jobs/housing performance evaluation will be used to identify areas where jobs or housing should be stimulated and encouraged. It would also be used to provide information about areas in which infrastructure deficiencies need to be corrected in order to facilitate a better jobs/housing balance. Interjurisdictional Coordination and Decision-Making The growth management program outlined here will not succeed without the cooperation and active participation of the County,the Local Agency Formation Commission,the 189 cities,and the service providers. These agencies and cities may view cooperation with the Count's nanagement program as a threat to their local authority over land use or other growth issues. The County's efforts to achieve cooperation must be aimed at persuading the cities and agencies that the growth management program will ultimately enhance their ability to meet their own General Plan goals. In addition, the County will participate in the cooperative planning process established by the (2gunpi vlr% 1%_11%.X%"&%T Iransportation .AuthoritvG.e.ff.wnt*,%.i...n:,:1 for the purpose of reducing the cumulative regional traffic impacts of development. *Now 4-14 Inter urisdictional cooperation would not require all of the cities and agencies to adopt the same goals,policies and implementation measures as will be 'included in the County's General Plan and growth management program. However, it would be desirable for the County to request that the cities and agencies adopt resolutions that specifically recognize and accept the growth management program and its premise. A key commitment by the jurisdictions involves the dedication of a relatively small,but adequate,level of staff time to assist the County in gathering the required data for the necessary planning studies. Additional commitments must be made on the part of policy makers and staff to review the annual land supply and development monitoring reports, consider them when making important planning decisions, and to actively participate in the growth management determination process every five years. Growth Management Determinations Building upon the preceding components of the growth management program, the final aspect of the process involves using the reports that have been generated to make the important decisions about where future growth in the County should be encouraged in order to minimize infrastructure costs and to enhance the overall level of "quality of life." The process for making these determinations is as important as the determinations themselves. The process can help to achieve consensus among cities and the County(in consultation with service providers)as to appropriate amounts and locations of new residential,commercial and industrial growth in the County. The growth management determination process should include the following steps,several of which are based upon information developed in the previous components of the program: 0 indicate on a County General Plan map the current city boundary lines,Spheres of Influence,the Urban Limit Line and current service areas for all of the major utilities/facilities; 0 add to the base map information regarding improvements or extensions to service systems that have been completed since the last review period or improvements itemized in capital improvement programs,as well as constructed and approved development projects and adopted General Plan Amendments; 0 identify lands that have been determined to be undevelopable; 0 identify on the map the geographic areas with infrastructure constraints and the locations of development projects that have been unable to meet performance standards; 0 review the annual land supply and development monitoring reports in conjunction with the performance standards and infrastructure constraints analysis reports to determine whether an adequate supply of vacant land is designated for urban use in the County and city General Plans,on both a Countywide and subregional basis, to allow the anticipated amount of urban development during the remainder of the twenty year period. This urban development must be subject to the 65/35 Land Preservation Standard. (See Section 3,Land Use Element.) 0 Determine whether adjustment to the urban limit line is needed in order to provide sufficient land to accommodate anticipated needs. Growth management determinations shall be made in consultation with the Goun. Trmisportation Authority. In it is anticipated that these growth - determinations, will be made in a series of joint meetings conducted on a subregional basis with representatives of the cities. The Local Agency Formation Commission(LAFCO)and the service districts should also be consulted. Staffwill present the base map and accompanying reports to the County and City Pbnning Commissions,LAFCO and service district boards,with a request that the agencies review the recommendations and make formal comments. After this review period is complete and appropriate changes,if needed,have been made,the map and reports will be recirculated to all of the jurisdictions in the County. The final action will be to request that the cities,LAFCO and service providers adopt resolutions in support of the recommendations and to initiate any General Plan Amendment hearings which may result from the review process. 4-15 Definitions of Terms The following definitions apply to the geographic terms used with respect to the Growth Management Element pregram only. The level of service designations for unincorporated County areas are shown in Figure 4-2. R,=. Rural areas are defined as generally those parts of the County that are designated in the General Plan for agricultural,open space or very low density residential uses,and which are characterized by medium to very large parcel sizes(10 acres to several thousand acres). These areas have very low population densities,usually no more MOM than 1 person per acre or 500 people per square mile. Suburban. Suburban areas are defined as generally those parts of the County that are designated in the General Plan for low and medium density single family homes; low density multiple family residences; low density meow neighborhood- and community-oriented commercial/industrial uses; and other accompanying uses. Individual structures in suburban areas are generally less than 3 stories in height and residential lots vary from about one fifth of an acre(8,000 or 9,000 square feet)up to 2 or 3 acres. Population densities in suburban areas fall within a wide ...ft range,from about 1,000 to 7,500 persons per square mile(1.5 to 12.0 people per acre). Urban. Urban areas are defiled as generally those parts of the County that are designated in the General Plan primarily INNNO for multiple family housing,with smaller areas designated for high density single family homes;low to moderate density commercial/industrial uses; and many other accompanying uses. Urban areas usually include clusters of residential buildings(apartments and condominiums)up to three or four stories in height and single family homes on relatively small lots. Many commercial strips along major arterial road are considered urban areas. 104 Examples of urban areas in Contra Costa County are the older neighborhoods in Richmond,El Cerrito,Pittsburg, and Antioch and the downtown commercial districts in smaller cities such as Martinez,Danville,and Lafayette. -- Population densities in urban areas are usually at least 7,500 persons per square mile (12.0 people per acre). Employment densities in commercial areas may range up to about 15 jobs per acre. Central Business District/Maior Commercial Center. Central business districts or major commercial centers are defined as those areas designated in the General Plan for high density commercial and residential uses. They consist of either the downtown area of a major city in Contra Costa County (Concord, Walnut Creek, and Richmond)or a large business/office complex(such as Bishop Ranch or the Pleasant Hill BART station area). AMMOO These areas are characterized by large concentrations of jobs and consist of clusters of buildings four stories or more in height. CBD's or major commercial centers generally have employment densities. mum N~ Now 4-16 `� 5.

TRANSPORTATION AND CIRCULATION ELEMENT 5.1 INTRODUCTION The purpose of this Element of the Contra Costa County General Plan is to establish transportation goals and policies, and to establish specific implementation measures to assure that the transportation system of the County will have adequate capacity to serve planned growth in Contra Costa County through the year 20209.The intention of this Element is to provide a plan and implementing measures for an integrated,multi-modal transportation system that will safely and efficiently meet the transportation needs of all economic and social segments of the County and provide for the transport of goods and services throughout Contra Costa County. The transportation system outlined in this Element recognizes on the one hand the limited availability of transportation funding and,on the other hand,increased demands for mobility within Contra Costa County. As a result,the Element emphasizes the efficient use of the existing transportation system,particularly existing roadways and transit systems,and cost effective enhancements to this system to accommodate planned growth consistent with the Land Use Element. Nonetheless,the County will continue to seek revenue from a variety of sources for needed transportation improvements and to work toward the establishment of new and creative funding mechanisms(i.e.,private/public and regional partnerships)consistent with the goals and policies of the Growth Management Element and Measure C- 1988. LEGAL AUTHORITY The Transportation and Circulation Element is prepared pursuant to Section 65302(b) of the California Government Code. This Element has been a mandatory component of local General Plans since 1955. The Transportation and Circulation Element is required to address the location and extent of existing and planned transportation routes, terminals, and other local public utilities and facilities. It is further required to be consistent with the other elements of the General Plan,accommodating future travel demand and contributing to,rather than inhibiting,the attainment of desired land use patterns in the Land Use Element. 5.2 RELATIONSHIP TO OTHER ELEMENTS Section 65300.5 of the California Government Code requires that the various elements of a General Plan comprise an integrated, internally consistent,and compatible statement of policies for the adopting agency. The law emphasizes that the Transportation and Circulation Element be coordinated with the Land Use Element. The transportation plan,policies,and implementing measures established by this Element comply with the requirement by utilizing the same projections of future population and economic activity as does the Land Use Element,by using the same geographic distribution of future population and economic activity as expressed in the Land Use Element map,and by designing the transportation plans and policies to contribute to the achievement of the planned land-use pattern. The Roadway and Transit Network Plans shown in this element have been constrained to reflect limited financial resources. Consistency with the Land Use Element is maintained through the interplay of these elements with the Growth Management Element. The Transportation and Circulation Element funding programs�e�e�-�tefor capital projects are correlated with the programs contemplated in the Growth Management Element. The Transportation and Circulation Element incorporates the implementation of the Contra Costa Transportation Authority's (CCTA), Expenditure Plan passed by the voters in November 1988. This Element also assumes availability of the revenue generated by Regional Measure 1,the Propositions 108, 111 and 116 approved by the 5-1 5.Transportation and Circulation Element Mow voters in June 1990,the California T'raffic Congestion Relief Act of 2000,and Proposition 42 approved by the voters m 2002. This element also asstunes maintenance of the various fee programs on new development established by the Cogn ,to constma the road facilities needed to seltiJe that development. The Board of Supervisors designated the CCTA as the Congestion Management Agency for Contra Costa County. The County -meets the congestion management planning requirements through the planning process established by the CCTA. A separate Scenic Routes Element was previously required as a mandatory General Plan component. However,state law now encourages the scenic routes'goals and policies be included within the Transportation and Circulation Element. Thus,this plan merges the scenic route discussion and policies into this Element. Biking,Hiking and Equestrian Trails Plans are included as part of the Recreation section of the Ptib.:'ke . N.-Open Space --- Element. It should be noted that some transportation related issues are included in other elements of the Contra Costa County General Plan. Policies that address the impacts of vehicle emissions on air quality,-#. +Me:are found in the Open Space/Conservation Element. The Noise Element also addresses transportation issues by identifying the .�.. noise impacts of traffic in the County,based upon the Roadway Network Plan and the traffic volumes that are forecasted on key roadways. The topic of oil and natural gas pipelines,often covered in Circulation Elements is discussed in the Safety Element. moon 5.3 RELATIONSHIP TO OTHER GENERAL PLAN DOCUMENTS The goals,policies and implementation measures contained in this Element are intended to guide planning for public and private projects that are subject to either approval of the County planning agency,or to review by County staff, although they may be under the jurisdiction of other public agencies operating in the County. Such goals,policies and implementation measures are further intended to be in accordance with other elements mom of the General Plan, as well as with other planning documents, such as the Contra Costa Transportation Autho it„y's Count3Afide C�'alnprehensive Transportation Plan '• The Transportation and Circulation Element is largely consistent with the Metropolitan Transportation Commission's -1-988-2001.Update of the Bay Area Regional Transportation Plan. The:EL�ist County Corridor and the 1-680 b swa�► through the State Route 24 interchange ...* .. . ,are not included in the Regional Transportation Plan. 5.4 ORGANIZATION OF TRANSPORTATION AND CIRCULATION ELEMENT This Transportation and Circulation Element addresses roadways,transit,bikeways,and transportation demand management(TDSM)programs,as well as air,rail,and water transportation facilities. The format of the Element is as follows: 1.M An analysis of existing and future transportation needs, e0m ed A,A IL N7 . . . 2. The fundamental concept that shapes this element. 3.{33 A presentation of �' ' ' . , goals, policies and implementation programs for each of the following topics: o Roadways and transit o Transportation System Management o Bikeways o Scenic Routes o Airports and Heliports o Ports and Proprietary Wharves 5-2 " 5.Transportation and Circulation Element o Railroads Note that the required discussion of terminals is provided as part of the treatment of airports,heliports,ports, proprietary wharves,and railroads. 5.5 EXISTING AND FUTURE TRANSPORTATION NEEDS Travel conditions in Contra Costa County are greatly influenced by its location on the eastern side of the San Francisco Bay metropolitan region(see Figure 5-1). Bridges,freeways,and trains link Contra Costa to every part of the Bay Area. Commute patterns are especially affected by the employment centers in San Francisco and Alameda County,and the residential areas of Solano County. Itis esri.rx�ated ttlat ? .. • nf.n I I • and 46 percent of work trips originating in Contra Costa are destined for another Bay Area county. Such inter-county travel patterns require that the Transportation and Circulation Element recognize the impacts � p of development outside Contra Costa County in addition to projected development inside the County. The Element accomplishes this task by incorporating projections of future population and employment activity in the remaining eight Bay Area counties for the year 2020-5. These projections were prepared by the Association -- f of Bay Area Governments,and were combined with the Contra Costa data to estimate the influence of regional growth on the level and orientation of travel in the County. Estimates of inter-regional traffic,primarily from the Central Valley,were also included in the forecasts. EXISTING NETWORK The County's transportation system is comprised of an;R"E ,• �r „.,n •� � *•d network of Federal, State and County roads, regional transit systems, bikeways, elderly and <1transportation services (paratransit),as well as air,water and rail service,and pipelines. Pipelines are discussed in the Safety Element. Roadways The County's roadway network includes Interstates 80,580,and 680,State Routes 4,24 and 242, ...Sta4e Route . In addition,numerous locally maintained arterials,streets and roads makeup the remaining network. Of special importance are the four bridges and three tunnels that link Contra Costa with the Bay Area Region. These include the Richmond-San Rafael Bridge,Carquinez Bridge,Benicia-Martinez Bridge,Antioch Bridge,and the Caldecott Tunnel. 5-3 Figure S-1 East Bay Regional Highway and Transit System ' , Sacramento Dixon Naps Yolo y Cou buy Pot x�.

Bus Bus service makes up the balance of the County's mass transit system. AC Transit serves portions of Western Contra Costa County with fixed bus service to Northern Alameda County and downtown San Francisco. The northwest portion of the County is served by the Western Contra Costa Transit Authority(WESTCAT),which operates both fixed-route and demand-response dial-a-ride buses. Central Contra Costa County is served by both fixed route and demand response buses operated by the Central Contra Costa Transit Authority(CCCTA),also called the County Connection. The eastern end of the County is provided both fixed route and demand-response bus service by the Eastern Contra Costa Transit Authority(Tri-Delta). Park and Ride Park and Ride facilities have been established throughout the County to encourage the use of transit and high occupancy vehicles. BART maintains twelve park and ride lots In Contra Costa providing over-1-I Ran 18,1)00 parking spaces forPALA 'BART .. - atron. s. Ten of these.lots are at BART stations and others are in Antioch and Brentwoodat • = • . Caltrans has established t# =teen-sixteen park and ride facilities in the County providing over€60 1.,600 spaces ,which are used primarily as staging areas for carpools and vanpools. ���H��.ILt wiciely 1 Bikeways County bikeways include both on-road and off-road facilities which are operated and maintained by the County,cities and the East Bay Regional Park District. According to a 2001 MTC Surygy for the nine-county Bay Area,bicycles account for 1.4 percent of all trips .. ,8 5 percent of . rthese trips are trips towyork. However,bikeways in the County are currently dominated by recreational users and are not widely used for commute purposes. The Counter is currently partigipatin,=in a countywide effort sponsored by CCTA to evaluate ..': ores ways of increasing the use of bicycles.for A. transportation-. Further discussion,as well as goals,policies and implementation measures,regarding bikeways are included in the "Parks and Recreation"section of the�i�iz -Open Space� Element. AMTRAK AMTRAK operates both long distance and intercity trains throw Contra Costa County. Intercity senrice is in.e.r.easing, 11. trains operate daily between Sacramento and Oakland thru Contra Costa 8 trains operate daily between Oakland and Bakersfield through Contra Costa County. ' , .. 5-5 5.Transportation and Circulation Element Air,Water and Railroads Several air,water,and railroad transportation systems and facilities are located within the County. A description and policies regarding Buchanan Field and the East County airports is found in the"Airports and Heliports"section. A similar description and relevant policies for water transportation facilities are included in the section "Ports and Proprietary Wharves",and rail-related facilities and policies are described in the"Railroads"section. EXISTING TRAVEL DEMAND The most comprehensive and recent data on local travel was collected from two sources,dttthe -- Metropolitan.Transportation Commission's(MTC)2.001 Regional Transportation Plan and the?000 Census Journ.ev to Work data.The.R.e zional Transportation Plan released by MTC;in 2001 rives a wene-ral over<=iew of reizional and local travel patterns within Contra Costa and the Bay Area. In addition the plan forecasts future .. travel demand,whicll is discussed in Ln-eater detail in following section.The 2000 Census data documents the travel data of 3,416,710 Bay=Area commuters and provides the most succinct oven4ew of where Contra Costa and Bay .Area Residents live and work. It should be noted that at the time of this revision staff from MTC;are evaluating how the.2000 Journey to Work Census Data,released in March of 2003 effects the data presented in the 2001 Re hona.l Transportation Plan as this plan was prepared prior-to the data released by the U.S.Census Bureau. 1 ' r • %.. . mom The.Metropolitan.Transportation Commission estimated that Contra Costa County residents made an average of 2 million vehicle trips in 2000, per day.

ABAG's projections for the year 22020 are provided at the 2000 Census Tract level. These tract-level forecasts were released as part of ABAG-'s 2002 Projections that report and provide forcasting data for the years 2000 through 2025.ABAG's projections are then agtrre:;ated and split into a reitional travel analysis zone systems consisting of 1,454 zones in the Bay Area) by the.Metropolitan Transportation Commission.

FUNDAMENTAL CONCEPTS THAT SHAPE THIS ELEMENT The projected increase in travel demand will require expanded transportation facilities and services, since existing facilities are strained to near capacity in one or bath directions during rush hours. The need to provide g1a a -expanded facilities poses both environmental and financial problems. The Transportation and Circulation Element can be used to guide, shape and control growth itself and should therefore relate to the issue of growth. However, it is only one component of a General Plan designed as a development, conservation and economic blueprint for the County. Roadway and transit improvements do not necessarily lead to uncontrolled growth. The Land Use Element and Growth Management Element set the timing and densities of future growth. A well-planned and balanced transportation network provides for and accommodates anticipated employment and residential growth and helps to relieve existing congested roadways. A defined transportation network also gives public and private interests a vision of needed improvements and an opportunity to assess costs and develop funding programs well in advance of actual growth. -- The following fundamental concepts have been recognized in developing this Transportation and Circulation Element: o Traffic flow is limited by the capacity of the system. o There are formidable limits to expansion and/or improvements to the system. o A desirable living environment and a prosperous business environment cannot be maintained if traffic levels continue to increase without limits. Various methods must be used to control and reshape the impact of automobiles in Contra Costa County and to "` � xtprovide convenient and reliable alternatives to commutintr alone by car. o When traffic demand sinificantly exceeds the capacity of the system, many negative effects can 5-8 5.Transportation and Circulation Element festuccur,including congestion,loss of time and productivity,accidents,personal frustration,increase in pollution,adverse community reaction;and use of residential streets for commuting purposes. o Contra Costa County,the Bay Area and California will continue to experience population growth over the next 20 years and transportation systems will continue to be strained. o Near-term solutions to conflicts between traffic demands and system capacity limits require utilizing existing roadways to the effective limits of their design capacity in order to rte-manage congestion. o Longer-term solutions require either significant enhancements to the system,fundamental changes in travel behavior patterns,or a combination of both. • Some of the specific approaches proposed in this Element for both near-term and longer-term solutions include the following: Place limits on the capacity of streets and highways which enter the County(near-term). — t rr&,,f ility,md gm nietxe of'irxand' ttwx itservice(bW4=4 — Expand undersized roadways and plan for new roadways(longer-term). Accept congestion untilrax-©rr,�...t;. E ""aS an in��1=itabl�� traffic condition dtrt-ing rush hours(near-term). �� — Improve the design of new development to provide alternative routes for circulation on the roadway system(near-and longer-term). Improve the design of new development to allow convenient aeeess t{ause of alternative forms of transportation. — Encourage ride sharing and staggered work hour programs(near-term). Construct HOV lanes and on-amp metering lights along commute corridors(near-term). o Even with the investment of$348.6 billion in State and Federal revenue to add to local funds for transportation improvements over the life of this plan, the amount of growth in the region and the attractiveness of travel by private automobile will make desired level of service standards (LOS) unattainable along portions of County roadways. 5.6 ROADWAYS AND TRANSIT INTRODUCTION The need for roadway and transit facilities is most directly tied to the land use patterns set forth in the Land Use Element. As described above,buildout of the land use plan through the year 20052020,together with anticipated growth outside of the County,would place excessive demands on the existing circulation infrastructure in the County. The goals,policies and implementation measures set forth in this section,together with those in the Growth Management Element,are intended to address the future circulation needs of Contra Costa County. ROADWAY AND TRANSIT NETWORK PLANS The Roadway and Transit Network Plans are the result of a coordinated planning process that incorporates the goals, policies and implementation measures of this Transportation and Circulation Element,in addition to the Land Use Element and Growth Management Element. As such,these network plans are a compromise between the ultimate 5-9 5.Transportation and Circulation Element transportation needs of the County,fiscal reality,and the potential development constraints imposed by the Growth Management Element. The premise of the Roadway and Transit Network Plans is therefore best sununarized as follows: o A roadway and transit network plan to accommodate travel demand that would result from assumed year?88-5-2020 buildout of the land use plan was developed. Fall ., . liam There is a shortfall in luldinl,to implement this plan. 9- A , , • r .. , ♦ ►. nc duan ./ o The combination of the 2 -Land Use plan with a Ffmancially Ggonstrained transportation network,and the provision of the Growth Management Element,will have the effect of slowing growth in the County until additional transportation revenues are secured and more efficient commuting habits are adopted. The �,�„� •���"�� �`��rt�.,�~1Wa Roadway Network Plan is shown in Figure 5-2. The. . Transit Network Plan is shown in Figure 5-3.

ROADWAY DESIGNATIONS AND DESIGN CRITERIA This section describes the classifications of roadways shown in the accompanying Roadway Network Plan. The purpose of the classifications is to define the Circulation Element's intent for the function and design of roadways specified in the Roadway Network Plan. Freeways womb Freeways are defined as controlled-access, high speed roadways designed to cavy high volumes of intercity, intercounty,and interstate traffic,although they may carry considerable local traffic in urban areas. This class of facilities is devoted entirely to the task of traffic movement, and performs no direct land service function. The onnap following design standards shall apply to freeways: 1. Opposing travel lanes shall be separated by a median. --- 2. Access shall not be permitted from abutting parcels. 3. Auxiliary lanes may be provided from one interchange to another in densely developed urban areas which have closely spaced interchanges or where substantial travel demand exits between two consecutive interchanges. now Expressways Expressways are defined as controlled-access,moderate speed roadways serving intercity or intercounty trips. Awaw This class of facilities is devoted entirely to the task of traffic movement,and performs limited land service function. Intersections may be at grade. The following design standards shall apply to expressways: 1. Opposing travel lanes shall be separated by a median if there are two or nx=travel lanes in each direction. 5-10 5.Transportation and Circulation Element 2, Access shall not be permitted from abutting parcels;however,access maybe allowed prior to iniproveinent of roadway segments to expressways standards if there is no alternative access route to a parcel. 3. Intersections with median breaks shall occur only at arterials or other expressways. 4. Acceleration and deceleration lanes may be provided at intersections. is r: o °O rrr r • ers•� O° • s � ' � R • waw ewe • • ••• -� / °° ab ° Q ... •� 0600 O°O a �^ °o ° U w d� a rr •.r• • i t ! • • i• e • • f F ! • r r•• '"w•faew � r r _ co o C o .•, ' 4• 0 N N {,n W a U1 0 C4 a> t7 ttS N r� Q ow �ee A` #low • _ e 0 � • cd E e r _ ■ • • o r r r • r • � /11 .

Their traffic function is of county-wide or intercity importance,rather than serving primarily local area traffic. Arterials mainly serve to move traffic,but they normally also perform a secondary land service function. 1 Access from abutting parcels may be allowed but shall be secondary to protection of the traffic serving function of the roadway. Driveways and parking shall be restricted or may be prohibited altogether to improve capacity and safety. 2. Opposing travel lanes shall generally be separated by a median if there are two or more travel lanes in each direction. 3. Turning lanes and deceleration/acceleration lanes shall be provided at intersections with roadways designated as arterials,or collectors,and are desirable at other intersections. 40 Rights-of-way at approaches to intersections with other arterials shall be sufficient to accommodate dual left-turn lanes. 5. Signalization shall generally give priority to through-traffic on the arterial. Collectors Collectors are for internal traffic movement within a community, carrying traffic to arterials and between neighborhoods. They are low speed roadways that do not ordinarily carry a high proportion of through trips and are not,of necessity,continuous for great lengths. Collectors may also serve to provide access to property, especially in rural areas. Access from abutting parcels in residential areas shall be discouraged. Driveways and parking may be restricted. Local Roads Local Roads are low speed,low capacity roadways that provide circulation within neighborhoods and access to adjacent land. Street design standards and layouts are used to discourage through traffic movements,avoid high travel speeds and volumes,and minimize neighborhood noise and safety impacts. Curbside parking is usually allowable. TRANSIT NETWORK CONCEPTS The Transit Network Plan corit lates,two different roles for public transportation: 1)provision of basic mobility for those individuals without access to automobiles or who are otherwise transit dependent;and 2)provision of an alternative means of travel for individuals with access to automobiles,especially peak-period conunuters. The Traftsit Network Plan establishes local transit service areas;areas where development densities will warrant the provision of fixed-route transit service by 20052020. Fixed-route transit operations are the prirY try means of serving the basic mobility needs for transit dependent individuals in urban areas of the County. The Plan assumes additional local bus service to BART stations,as well as the LMlementation of the e-BART concept from the.PittsbW-v_/Bav Point BART 4 DittsLums anci A ntioniq A%%J'AL JLL&T'X%.R%."LJL0 station to Byrome. 4 The Transit Network Plan establishes transit corridors along the county's freeways in order to provide speedconvenient and reliable alternatives to driving alone on congested freeways. Within these corridors,the County will pursue the construction of rail transit ek.-tensieffis service and high occupancy vehicle facilities,the establishment of express bus service,the integration of rail transit and bus service,and the promotion of carpools and vanpools. Existing and proposed studies will identify the feasibility of improving specific transit operations in A%0.9.1 XW A A 16 9.1 DI the Transit Corridors.

Design and allow for on-road bikeways on arterials and collectors as an alternative to car travel where this can be safely accommodated. 5-aj. Cooperate with MTC in its effort to increase tolls on regional bridges serving the County to help pay for alternative transportation service. 5.7 TRANSPORTATION DEMAND MANAGEMENT Transportation Demand Management(TDM)is oriented towards encouraging efficient use of existing transportation facilities during peak periods of travel TDM recognizes that large scale investments in highway and transit facilities are frequently limited by the availability of financial resources and adverse commnw reactions. TDM measures usually.l) involve lower capital costs; 2)provide incentives designed to modify travel demand; 3)are implemented by local government or the private sector,and 4)give all travel modes equal consideration in providing access to development~ The County currently promotes TDM strategies in unincorporated areas through certain County ordinances. Even with substantial investment in transit facilities, driving alone is likely to remain the choice of most county residents who commute. The County should continue to monitor the effectiveness of its zonine and 5-21 5.Transportation and Circulation Element subdivision ordinances to ensure that new development promotes a balanced transportation system and does not solely rely on the automobile.

Development of a comprehensive bikeway system within these areas would provide further incentive to commute by bike. A comprehensive bikeway system is defined as a system of bike paths,bike lanes,and bike routes interconnected f-- and spaced closely enough to satisfy the travel needs of most cyclists. Many existing bikeways are of a recreational design combined with pedestrian trails and located off-street. These facilities should be supplemented by on-street commuter bikeways that provide direct access to commercial uses. NNOW "Bikeway"means all facilities that provide primarily for bicycle travel. The following categories of bikeways are defined in the California Streets and Highway Code. ANWW o Class I Bikeway(Bike Path or Bike Trail):Provides a completely sepated right-of-way designated forthe exclusive use of bicycles and pedestrians with cnossflows by minin�iz�ed. o Class H Bikeway(Bike Lane): Provides a restricted right-of-way designated for the exclusive use or semi-exclusive use of bicycles with through travel by motor vehicles or pedestrians prohibited,but with vehicle parking and crossflows by pedestrians and motorists permitted. o Class III Bikeway(Bike Route): Provides a right-of-way designated by signs or permanent markings and shared with pedestrians or motorists. .•.. .In.M,u ch of 2002 the Contra Costa Transporaition Authori initiated a cooperative effort«l-ith the cities and the coirnt�tc? piWare a Count de Bi 1e and Pedestrian.Plan.

This plan has two basic purposes: it enables the County to request that the State designate state routes to the State highways program,while at the same time providing a local scenic route implementation program. Such a plan provides recognition of the perception we have of our surroundings while traveling through the County. Presently Contra Costa County has numerous roadways that pass through areas affording pleasurable views. The number of such roadways where scenic quality exists will diminish,however,unless protected. Their character is changed through improvements to them or when land adjacent to them is developed. This plan identifies a Countywide scenic route system and ensure that new projects approved along a scenic route are reviewed to maintain their scenic potential. Most scenic routes depend on natural landscape qualities for their aesthetics and many formally designated scenic routes have been established in predominantly rural areas in the past,but neither natural beauty nor rural settings are necessary to the designation of scenic routes. DEFINITION AND MAPS OF SCENIC ROUTES For the purposes of this plan, the following definitions will apply; they should aid in understanding the relationship of the scenic roads to their environs. A scenic route is a road,street,or freeway which traverses a scenic corridor of relatively high visual or cultural value. It consists of both the scenic corridor and the public right-of-way. The public right-of-way includes the roadbed and adjacent lands in public control. It includes lands utilized for roadway protection,storm drainage,public utilities,pedestrian travel,and roadside plantings. Usually this land is owned in fee or dedicated to local jurisdictions or the State. It should also include cycling or hiking trails,roadside rests,or turnouts,etc. Public projects in the right-of-way should be designed and carried out recognizing the purpose of this plan. Semi-public rights-of-way include railroads,canals,or power transmission lines. A scenic corridor is usually much wider than the road right-of-way and extends to the contiguous areas beyond it. Width of scenic corridors will vary greatly depending upon the present degree of development, land forms, topography,and the nature of scenic quality. The scenic corridor consists of much of the adjacent area that can be seen from the road. It is within this area that development controls,dedication,and the purchase of easements or lands in fee simple will be required,and public projects will be reviewed for compliance with this plan. Controls should be applied to retain and enhance scenic qualities,restrict unsightly use of land,control height of structures, and provide site design and architectural guidance along the entire scenic corridor. Route 24 from the Alameda County line to the Interstate 680 interchange,and Interstate 680 south of that interchange to the Alameda County line,are existing State designated scenic routes within the State Scenic Routes program. Route 4 from Hercules to the intersection with Railroad Avenue is proposed for State designation as is the proposed State Route 94.Bypasis to the Delta. While the State Scenic Routes plan forms the skeletal ork for the County Scenic Routes program,Figure 5-4 identifies the other roadways which form the Countywide scenic routes plan.Inclusion on this map provides direction to 1 -C9on staffto review projects m a fashion which is compatible with the scenic qualities ofthese roads. Scenic routes are shown for the unincol rated-cu:eas:routes with scenic potential or to connect scferntc areas are shown as conn .. ectingroutes.

Additionally,there are ._ several private airfields which operate in the county and requests for heliports have been received from time to time. This section adds policies to the County General Plan which guide the use of airports,private airfields and heliports. The overall goals and policies for airport and heliport operations in the county are outlined in the next two sections. A more detailed description and policies for Buchanan Field and the East.t . w*Byron Airport are included in separate sections below. Finally, special policies required by the Airport Land Use Commission are included following the ._.. discussion of the two airports. The noise contours for these airports are included within the Noise Element of this Plan. AIRPORTS AND HELIPORTS GOALS 5-S. To encourage the development and operation of two general purpose public airports in the county. 5-T. To allow heliports,restricted to appropriate locations, that would add to the economic well-being and safety of the county. AIRPORTS AND HELIPORTS POLICIES MOMW Overall Policies 544. Regulate the location of private airfields and heliports to minimize their impacts on adjacent residents, sensitive receptors,and to ensure public safety. --r 545. Protect the Byron Airport environs from urban encroachment through a combination of land acquisition, easement acquisitions and land use regulations. ... 546. Work with adjacent cities to ensure that Buchanan Field Airport environs are developed and redeveloped in ways which protect the public safety and maintain the viability of the airport. 547. Work with the FAA and helicopter operators to minimize conflicts with residential areas and sensitive land uses, such as schools,hospitals,residences,and other sensitive noise receptors. Policies Regarding Buchanan Field Buchanan Field is located on a X95 acre site in the unincorporated area of Contra Costa County adjacent to the cities of Concord and Pleasant Hill;a very small portion of airport pmoperiy is located within Concord. It is a general use airport and has provision for scheduled commuter airline service. The land use plan designations for this airport are shown on the Land Use Element map. Land uses allowed on Mow the airport property should enhance the airport function and be consistent with its goals and operational requirements. Most of the site is designated "Public/Semi-Public"to reflect the airport use.—� 4a Special policies of this plan that apply to Buchanan Field are as follows: SNOW 548. The Transportation and Circulation Element requires the construction of the Diamond Boulevard extension from Concord Avenue northerly to Center Avenue as a condition of approval of development projects on the western side of the airport to major new uses. 549. The Buck Field Golf Course exists on the southwest edge of the airport adjacent to the intersection of Concord Avenue and I-680. The road improvements called for by this plan,and in particular the Diamond -- Boulevard extension, will require modification to the existing golf course. This plan encourages the 5-26 "� 5.Transportation and Circulation Element maintenance of a small golf course or some other recreation facility in the location of the golf course. 5-50. Passive recreational uses are appropriate in the approach path of the airport and will constitute an environmental enhancement and balance to serve as amenities for the development at the airport. Some maintenance responsibilities for these recreational facilities may be required of the airport projects. 5-51. Trail connections surrounding the airport are required. A riding,hiking and bicycle trail is shown along the Walnut Creek Flood Control Channel. Hiking and bicycle trails are shown flanking the airport on its remaining perimeter. These trails will serve as an amenity to the new office facilities in the area,as well as providing a connection to a regional trail linkage along the Walnut Creek Channel. ContraEast •Byron Aires The County has developed a -full-service general aviation airport ata site adjacent to the e:-moo Town of ByronAir ffiL The project location is approximately three miles south ofthe town ofByron and 2%2 miles north ofthe Alameda County line. The Byron Highway passes one mile to the northeast. Long range plans call for construction of a runway capable of serving 250,000 operations annually,and construction of parking to accommodate 250 aircraft. The airport acquisition and development was jointly funded by the County,the State and Federal Governments. The airport boundaries encompass 1307 acres of which only 230 93 acres will be available for airport and compatible purposes. In addition to the land to be acquired in fee,an additional 2,000 acres of conservation easements may be acquired to preclude additional residential development and to control noise,height of structures,etc. In addition, aviation easements within two miles ofthe airport will also be acquired,later if needed,to assist in controlling development. The expressed intent of the County is to have a second airport free from urban encroachment,and to prevent the establishment of related commercial or industrial development around the planned airport Water and sewer services will be limited to serve only the airport;utilities will not serve growth on the adjacent properties. It is also for this reason that extra rights-of-way beyond the airport development proper are being acquired. Additionally,no residential development or sensitive receptors, e.g. hospitals,schools,etc.,should be allowed within the projected 60 CNEL noise contours for the new airport. (For information only,Measure C-1990 provides that one of the enumerated bases for changing the Urban Limit Line,upon a4/5 vote,substantial evidence and public hearing,would be the following finding. (f)an objective study has determined that a change to the Urban Limit Line is necessary or desirable to further the economic viability of the East Contra Costa County Airport,and either(i)mitigate adverse aviation related environmental or community impacts attributable to Buchanan Field, or(ii)further the County's aviation related needs.) Special policies of this plan that apply to the East County Airport are as follows: 5-52. The County shall acquire fee title and/or conservation(development rights)easements to an appropriate amount of buffer land around the planned East County Airport. 5-53. The buffer land or conservation easements acquired around the airport shall ensure that incompatible uses will not be allowed to locate within the safety zone. 5-54. Establishment of commercial,industrial or residential development around the planned airport shall not be allowed 5-55. Water and sewer services to the airport will be limited to serve only the airport properties; utilities will not serve growth on the adjacent properties. 5-56. No residential development or sensitive receptors,e.g.hospitals,schools,etc.,shall be allowed within the projected 60 CNEL noise contours for the new airport. Special Policies Regarding the Airport Land Use Commission The Public Utilities Code requires that the intent and purpose of adopted Airport Land Use Commission(ALUC)plans and policies be incorporated into the County General Plan. The following policies apply to the two County airports: 5-57. Structural heights shall be designated by the Federal Aviation Regulations(FAR)Part 77 surfaces associated with the various runway designations shown on the latest Airport Layout Plan. 5-58. The Structural Height Limits defines maximum structural height. Height limits will be placed on new 5-27 5.Transportation and Circulation Element buildings,appurtenances to buildings,all other structures and landscaping in accordance with the Airport Layout Plan except in special instances when for reasons of safety the Commission may impose a more restrictive structural height. An applicant for any structure within the Airport Land Use Commission Planning Area proposed to penetrate any height limit surface shall submit an aeronautical analysis which specifies the proposed project's effect on airport instrument procedures for all runways,the effect on airport utility,and the effect on overall aviation safety. If,after reviewing the aeronautical study and other related information,it is determined that the proposed project would not have an adverse effect on safety and airport utility then,the project may be approved for heights other than those indicated by the FAR,Part 77,Structural Height Limits. 5-59. All major land use actions within the Buchanan Field and Byron Airport Influence Areas as shown upon Figure 5-5 shall be referred to the Contra Costa County Airport Land Use Commission for comment. The definition of what constitutes a major land use action is found on pages 2-6 through 2-8 of the Contra Costa County Airport Land Use Compatibility Plan adopted in December of 2000. If it is unclear whether or not an action falls within this listing,the County should err on the side of caution and refer the matter to the ALUC staff. Gomm 5-60. New construction or building exterior alterations located in areas of terrain penetration as defined by the ALUC Airspace Protection Surfaces will be reviewed on a case by case basis with consideration given to topography,flight patterns,existing vegetation and other factors which might affect airspace and safety. The County will rely on ALUC land use compatibility guidance and programs for considering airspace safety analysis issues and height limitations of structurers. 5-61. Temporary structures,such as construction cranes or antennae,which would penetrate any adopted height limit surface,may be allowed after a case by case review,provided that obstruction lighting and marking is installed and a two week notice of temporary structure emplacement is provided by the proponent to the County Manager of Airports. Temporary structure emplacement shall be subject to reasonable time limit. 5-62. The County may require an exterior building materials reflectivity analysis upon review of the proposed types of building materials, building height, and building location and use on site. Such analyses should be required for development of any structures on or adjacent to public airports which would be over three stories in height and utilize reflective surfaces. Reflectivity studies shall address the potential for pilot and airport operation interference,proposed mitigation to any identified potential interference resulting from reflected sunlight,and any other subject areas related to reflectivity which the County may deem appropriate. The County may include some or all of the proposed mitigation in its project approval process. " 5-63. Within each safety zone designated by the ALUC, the following are incompatible uses (The ALUC Airport Influence Area Maps for Buchanan Field Byron Airports are shown on Figure 5-5.): (1) Any light source which would direct a steady light orming light of red,white,green,or amber color associated with airport operations toward an aircraft engaged in an initial straight climb following takeoff or toward an aircraft engaged in a straight final approach toward a landing at an airport,other than an FAA approved facility. (2) Any construction which would cause sunlight to be reflected toward an aircraft engaged in an initial straight climb following takeoffortoward an aircraft engaged in a straight final approach toward a landing at the airport. (3) Any use which would generate smoke, attract large concentrations of birds, or may otherwise adversely affect safe air navigation within a safety zone. (4) Any use which would generate electrical interference that would be detrimental to the operation of aircraft and/or aircraft instrumentation. (5) Any use which would utilize or cause to be stored highly toxic,inflammable or otherwise hazardous materials which, in the event of an aircraft accident, could be released into the surrounding ..._ environment to threaten human life or property. (6) Within the safety zone clear area,any use which involves the erection of a permanent above ground structure other than FAA approved facilities. -- (7) Within the safety zones,excluding the clear areas,any use which on a regular basis would result in a density(excluding streets)in excess of 30 persons per acre or one person/500 square feet of gross 5-28 AN& 5.Transportation and Circulation Element building flood area,whichever is less. (8) Any of the following uses:new single and multiple family residences,shopping centers,restaurants, schools,hospitals,arenas and other places of public assembly. 5-64. The following are suggested uses within the ALUC Compatibility Zones for Buchanan Field: (1) agriculture; (2) open space; (3) warehousing; (4) light industry; (5) parking of automobiles;and (6) low occupant density public uses,such as sewage treatment plants. 5-65. Within the ALUC Compatibility Zone B-1,no new lot splits shall be allowed and buildings on existing lots of record shall be located as far as practical from the extended runway centerline and shall be limited to two stories in height. The following are suggested uses within the ALUC Compatibility Zones for the East Contra Costa Airport (1) agriculture; (2) open space; (3) low intensity park and recreation uses; (4) low occupant density public uses;and (5) parking of automobiles. 5-66. Airports and heliports may be allowed by issuance of a land use permit in zoning districts found by the Board of Supervisors to be suitable for such uses. 5-29 AL cr10. z:1 4 .................

Create a new zoning district for County airports similar to the Planned Unit(P-1)District zone which provides for public review of on-site projects,and rezone both airports to that district. 5-ap. Review county ordinance code provisions and consider the suitability of each zoning district for the establishment of airports and heliports. 5-aq. Continue to regulate all heliports in the county by the land use permit process. 5-ar. Create a new zoning district to regulate private land use on the two public airports. 5-as. Undertake hearing to rescind the"Airport Zoning Plan for Buchanan Field"adopted in 1955,and to approve preparation of an updated structural height limit plan. 5-atiat. The subdivision ordinance should be amended to require the following actions prior to recording a final map for the ALUC Planning Area: (1). Dedication of suitable aviation and noise easements for the area of the particular subdivision; (2). Require the developer to record a covenant or provide other nis rwinAstom*prospective buyers of lots that the property may be subject to frequent overflight and associated noise impacts. 5-a=au. Any project in an area near the Buchanan Field airport with a designated noise level of 60 BA decibel CNEL or greater as shown on the Projected Noise Levels Map shall be required to attach a statement to any deed, lease,rental agreement, or Covenants, Conditions and Restrictions document pig to the use of the pry. The statement shall indicate that the property is subject to aircraft overflight,and associated noise irripacts. 5-agar An acoustical study shall be required for any discretiormyresidential project which the County will consider which is within the area designated on the Projected Noise Levels map to exceed 60 dBA level. The study should be submitted prior to accepting the application as complete and shall be by a certified noise acoustical firm. 5.11 PORTS AND PROPRIETARY WHARVES INTRODUCTION Contra Costa has historically been oriented to its waterfront,since the western end of the County is located on San Francisco and San Pablo Bays,and the northern shoreline fronts along the Carquinez Strait, Suisun Bay and the Sacramento San Joaquin River Delta. Industrial development in the county was concentrated along the shoreline,and this legacy remains today with port-oriented heavy industrial uses located in scattered locations from Richmond to Antioch. These industrial uses are important to the county economic base and the continued use of appropriate shoreline areas for heavy industries that rely on water traffic should be protected. There is one major deep water port in the county,the Port of Richmond,located in that city. In addition,there are several private ports or proprietary wharves,which serve large petroleum refineries and other industrial firms. PORTS AND PROPRIETARY WHARVES GOALS 5-U. To maintain the economic viability of the county's existing ports,wharves,and shipping lanes. PORTS AND PROPRIETARY WHARVES POLICIES 5-67. The continued use of existing ports and pr+aprietaxy wharves shall be recognized and encouraged. 5-31 5.Transportation and Circulation Element 5-68. Water-oriented industrial uses which require deep water access shall be encouraged along the shoreline,while other industrial uses which could be located on inland sites shall be discouraged 5-69. New or replacement proprietary wharfs shall be allowed adjacent to industrial use areas,as long as environmental safeguards are followed and public access to the shoreline is provided. 5-70. The County shall advocate maintenance of deep water channels at a depth that keeps ocean vessel use viable from San Francisco to the Army's Military Traffic Management Command former Concord Naval Weapons Station). 5-71. The Concord Naval Weapons Station deep water port should be utilized for private port use if the property ever becomes excess government property. PORTS AND PROPRIETARY WHARVES IMPLEMENTATION MEASURES 5-9-y . The County shall continue to work with the Bay Conservation Development Commission,the State Lands Commission,and other appropriate agencies to ensure adequate deep water access is provided to industries along the county's shoreline. ,.... 5-azax. The deep water site at Selby should be reserved for a water-related industrial use. 5.12 RAILROADS -- INTRODUCTION There are four railroad lines which currently carry freight within Contra Costa County. The Southern Pacific railroad .� line,now owned by�'��T �~ y��� �����'�'nn�� Union:Pacific(LJP).stretches 60 miles from Richmond to the Alameda County line near Clifton Court Forebay. The WUP line is a high speed double track between Richmond and Martinez,and carries by far the most freight traffic of all the railroad corridors in the County. From Martinez,the 8RUP track splits,with one track crossing the river to carry freight up the S.�ento Valley to the northwestem U.S.,and one track(kno«n as tile"Mcxoco.tine")continuing through Antioch,Oakley,Brentwood,Byron Trac ,and into the San Joaquin Valley and points south. The:Moc(xo line is seldom used by U.P and niay be acquired by BART for operation of a planned conlinuter rail ser--ice in East Couii!yl. The 55-mile long Burlingrton Nor-theni Santa Fe (' BNSF)railroad corridor roughly parallels the SUP line between Richmond and Hercules,where it then turns inland through rural Franklin Canyon �. running south of Route 4 to the industrial areas east of Martinez. From there it again closely parallels the&RUP(and Sacramento Northern/Union Pacific)tracks as it passes through Pittsburg and Antioch,and then through Oakley and across the Delta to Stockton. . ' -U. • , .� .. Two smaller freight lines also operate in the County. Union Pacific controls the subsidiary Sacramento Northern line from Clyde to Pittsburg, and the Bay Point and Clayton rail line serves the T' tea An1iy's Military Traffic;:Management Command. The other major railroad corridor in the county,the SP tracks running north-south between Concord and through the San Ramon Valley to the Alameda County line,was abandoned in the 1960s and has been largely acquired by the County�•ith the assistance o state funds res er.,ed for implementingr,mass transit systems. This abandoned SP San:Ranson Valley Branch Line is now Imo;y1 as the Iron Horse Corridor. CulTently it is used as a trail by pedestrians and bicyclists.and for pipelines and utilities operated by Dublic and pfivate entities. The Counly is d.evelo 1in T a management pro gmm for the Iron Horse Corridor. starting witll a Landscape Element that wws approved by the :Board of Superyisors in 2000. The County's management pro ant reserves a portion of the Iron.Horse Corridor for future use as a rail transportation line,per the requirements of the state wants that enabled the Count; to o acquire the richt-of-way. The poi tion.of the Iron Horse Corridor that is used as a trail is maintained by the East Bay Regional Park District. Tl1e same tracks used and oNN-med by freight railroads also carry an.increasing_number of passenger tains.

The importance of railroad lines is further increased by the growing ridership of intercity passenger trains serving the County, and future plans for urban, commuter, and intercity rail passenger service to provide alternatives to the region's freeway congestion.

HOUSING ELEMENT 6.1 INTRODUCTION The development and preservation of housing is important to all the people within Contra Costa County. To plan for the development of adequate housing for all income segments, a housing element is Im pared as a part of the Geneml Plan. This document constitutes the Housing Element,which specifically addresses housing needs and resources in the • County unincorporated areas. Section 6.1, Introduction of this Element reviews the geographic areas covered by the Contra Costa County Housing Element, the purpose and content of the Element, the public participation process undertaken to assist in the development of the Element,and its relationship with the rest of the General Plan. A. Community Context 11 County Geography Established in 1850, the County of Contra Costa is one of nine counties in the San Francisco Bay Area. The County covers 733 square milesof`land area and extends from the northeastern shore of San Francisco Bay easterly to San Joaquin County. The County is bordered on the south and west by Alameda County and on the north by Suisun and San Pablo Bays. The western and northern communities are highly industrialized,while the inland areas contain a variety of urban,suburban/residential,commercial,light industrial,and agricultural uses. Contra Costa County is comprised of large unincorporated areas and the cities and towns of Antioch,Brentwood,Clayton, Concord,Danville,El Cerrito,Hercules,Lafayette,Martinez,Moraga,Oakley,Orinda,Pinole,Pittsburg,Pleasant Hill, Richmond, San Pablo, San Ramon,and Walnut Creek. The unincorporated areas include the following communities: Alamo,Bayview-Montalvin Manor,Bay Point,Bethel]sW4 Blackhawk,Byron,Canyon,CrockM Diablo,Discovety Bay,East Richmond Heights,El Sobrante,Kensington,Knights n,Mountain View,North RichrnoricL Pacheco,Pleasant Hill BART, Rodeo, Rollingwood,Tara Hills, and Vine Hill. The incorporated cities and towns are separate political entities;the unincoporated areas are within the land use jurisdiction of the County government. The County is large and diverse. It encompasses several housing sub4narkets,which we determined by a combination of topography, historical development patterns, and social and economic phenomena. In general, the County can be divided into three primary subregions—West,Central,and East West County is urbanized with a developed industrial base. Central County is a rapidly urbanizing area with much new office and light industrial development East County has historically been y agricultural but is now experiencing considerable residential development Figure 6-1 illustrates the geographic relationship between the cities and towns and the unincorporated areas. This Housing Element is concerned with the housing needs,constraints,resources,and solutions for the unincorporated areas. 2. County Residents The 2000 Census indicates that Contra Costa County is home to 949,000 residents,making it the ninth most populous county in California. Several cities experienced - Li4flucc-urit population growth during the last decade. In particular, the City of Brentwood population tripled in ten years,experiencing a growth of 2080/6. Other connnunifies with significant growth include Clayton(47%).Antioch(46%).Oakley(390/6),Danville(33%).,and San Ramon(27%). 71be uninco ted areas of the County had a population of 151,690 in 2000,repmmmtirig an increase of 14%since 1990. Countywide growth was 18%during the same period. Residents have been athacted to Contra Costa County in the 1990s xfinarily due to the availability of rapid trarisit,close proximity to major employment centers in Oakland,San Francisco,,and the Silicon Valley, as well as employment growth within the County along the 1-680 corridor and Tri-Valley area. The relatively affordable housing prices in the County compared to other Bay Area counties also contribute to the population growth. Like the rest of the Bay Area, the County has become more edinically diverse in recent decades. The number and proportion of Hispanic and Asian residents have increased considerably,according to the 2000 Census.' The number of families is also growing in the County, indicating the continued need to provide adequate affordable housing, including first-time homebuyer and move-up housing opportunities. VA�ile the number of Black residents has increased,its proportion of the County population has remained at slightly over 9%. 6-1 6. Housing Element Contra Costa County has one of the fastest growing work forces among Bay Area counties,with growth in its employment base driven primarily by the need to provide services to an*increasing local population. Nevertheless,the number of white- collar jobs has increased in the County due to the decentralization of office-related employment to the County from other parts of the region,particularly San Francisco. However,the Association of Bay Area Governments(ABAG)expects that Contra Costa County will continue to provide"bedroom communities"for the workforce of other Bay Area counties. The County is expected to gain nearly 23,000 more employed residents than jobs between 2000 and 2020. 3. County Housing Market Single-family homes are the predominant housing type in the County. This is especially true in the unincorporated areas, where single-family dwellings comprise 80%of the housing stock. Multi-family units account for 14% of the housing units.,while the iernairung 6%are mobile homes. Although home prices are more affordable in Contra Costa County than m most areas in the Bay Area,housing affordability is still an important issue affecting many residents in the County. A significant number of lower- and moderate-income households spend more than one-third of their incomes on housing.2 This level of housing payment is typically considered as burdensome to lower-and moderate- income households and suggests that income growth has not kept pace with the increase in housing costs. Neighborhood and housihg quality is another issue in unincorporated County areas. About 46%of the housing stock in unincorporated areas is thirty years or older, the age when most homes begin to have major repair or updating needs. In particular, significant housing rehabilitation needs have been identified in the Bay Point, North Richmond,and Rodeo redevelopment project areas. Contra Costa County is faced with various important housing issues: preserving and enhancing the affordability of housing for all segments of the population; providing new types of housing in response to changing demographic trends; L",Arm and improving the quality of the housing stock;and achieving a balance between employment and ' housing opportunities. This Housing Element provides policies and progxrs to address these and other related issues. B. Role and Content of Housing Element Ae availability of housing is of vital The Housing Element of the General Plan has two purposes: statewide importance, and the early (1) to provide an assessment of both current and future attainment of decent housing and a housing needs and constraints in meeting these needs;and suitable living environment for every (2) to provide a strategy that establishes housing goals, California family is a priority of the hi policies,and programs. hest order.g This Housing Element represents Contra Costa County's long-term California Government Code, Section commitment to the development and improvement of housing with 65580 specific goals for the short term,, 2001-2006. This Element identifies strategies and programs- that focus on: (1) preserving and improving housing and neighborhoods; (2) providing adequate housing sites; (3) assisting in the provision of affordable housing; (4) removing governmental and other constraints to housing investment;and (5) promoting fair and equal housing opportunities. The Housing Element consists of the following major components: • An introduction reviewing the purpose and scope of the Element(Section 6.1); • An analysis of the County's demographic profile,housing characteristics, and existing and future housing needs(Section 6.2); • A review of potential market, governmental, and environmental constraints to meeting the County's identified housing needs(Section 6.3); • An evaluation of the land, financial, and organizational resources available to address the County's identified housing needs goals(Section 6.4); • An evaluation of accomplishments under the adopted Housing Element(Section 6.5);and • A statement of the Housing Plan to address the County's identified housing needs, including housing goals,policies and programs(Section 6-6). 2 -1be S=e Dep=MM Of I-JOUSn and GDMMMMty Development {HCS) has established four income categories based on County median fz* uxorne(RFS. Very low-mcorrie households am those eammg uxonr up to 50%of the County MR. Low-income households am those eammg 51 to 80% of the County MR. Combined,the very low- and low-income households are referred to as lower-income households. Maden to-income households am those eaming 81 to 120P/o of the CmmyMFI.

Housing Element C. Data Sources Various sources of information are used to prepare the Housing Element. Data from the 1990 Census on population and housing are used to a large extent in the Element. Although dated, the 1990 Census remains the most comprehensive and widely accepted source of information until detailed data from the 2000 Census is available. Where possible, preliminary data from the 2000 Census have been incorporated in the Element. Several data sources are used to update the 1990 Census and supplement limited 2000 Census information: • Demographic and housing data provided by the Association of Bay Area Governments and the State Department of Finance; • Housing market information, such as home sales,rents,and vacancies, is updated by surveys and property tax assessor's files, • Public and nonprofit agencies are consulted for data on special needs groups, the services available to them,and gaps in the system;and • Lending patterns for home purchase and home improvement loans are provided using the Home Mortgage Disclosure Act{NMDA)database. D. Public Participation The County encourages the participation of residents and local agencies in the process of identifying housing needs and formulating housing policies and progrya i . During the development of the Housing Needs Assessment(Section 6-2), the County consulted with and/or obtained information fi-om a variety of organizations serving low- and moderate- income persons and those with special needs. These agencies are referenced throughout the document. In gyration of the Housing Element,opportunities were provided for the public to help shape the County's housing goals,policies,and strategies. Two publicly noticed study sessions for the Planning Commission were held to discuss 4MOM housing needs and community concerns and discuss and policies, respectively. Over 300 groups and individuals were notified of the study sessions,including representatives fivin the following general categories: • Board of Supervisors/County departments • County cities and towns • Other local,State,and federal government agencies and special districts • Transportation committees • Municipal Advisory committees • Chambers of Commerce • School districts • Libraries • Housing developers/advocates • Real estate associations • interfaith groups • Interested individuals • News media Specific agencies were contacted directly to encourage in the study sessions. Private citizens and mIxesetitatives from for-profit and non-profit housing developers and service agencies ceded the study sessions.Public input received has been incorporated into the Draft Element for review by the State Department of Housing and Community Development(HCD). In addition,County staff spoke on the Draft Housing Element at meetings of the following groups: • Area Office of Aging • Contra Costa Interfaith Coalition • Mobile Home Advisory Committee • Faith Works! • Contra Costa Continuum of Care Board To adopt the Housing Element, public hearings were held before the Planning Commission and County Board of %mom Supervisors. Notices were published in local newspapersin advance of each hearing and copies of the Draft Element were made available for public review at selected County government offices,public h-braries,and other public locations in the unincorporated areas. Drafts of the Housing Element were also posted on the County website at www.cocoplans-org. 64 6. Housing Element E. Relationship to the General Plan The 2001-2006 Housing Element is a key component of the County's General Plan. The County of Contra Costa adopted its General Plan in 1991, which includes the following elements: Land Use; Growth Management-, Transportation and Circulation;Housing;Public Facilities/Services;Conservation;Open Space;Safety-,and Noise. The Housing Element Wilds upon the other adsting General Plan Elements and is consistent with the goals set forth in those elements. The Housing Element goals should be interpreted and implemented consistent with other General Plan goals. A consistency matrix identifying the related goals is provided on the following page. For each housing goal presented in this Housing Element,the related goals in each General Plan Element are identified by number. For example,Goal 3-D in the Land Use Element calls for"[the provision ofl a range and distribution of land uses that serve all social and economic segments of the County and its subregion." This Land Use Element goal is consistent with the intent of Housing Element Goals 4,6,and 8 reliating to the provision of a range of housing choices to all social and economic segments of the population. The County will ensure consistency between General Plan elements so that goals and policies introduced in one element are consistent with other elements. If it becomes apparent that over time, changes to any element are needed for internal consistency,such changes will be proposed for consideration by the Planning Commission and County Board of Supervisors.

To accomplish this goal,a comprehensive assessment of the housing needs of the region must be conducted. Section 6.2,Housing Needs Assessment presents and analyzes the demographic,socioeconomic,and housing characteristics of the unincorporated County areas to determine the nature and extent of housing needs. Until the detailed 2000 Census data are available,the 1990 Census remains the most comprehensive and widely accepted source of information for describing the demographic,housing and socioeconomic profiles of a community. As such,data 6-5 6. Housing Element from the 1990 Census are used to a large extent in this housing needs assessment. Where possible,the 1990 Census and mom& preliminary 2000 Census data are supplemented with current market data and secondary sources of information. A. Population Characteristics The type and amount of housing needed in a community are largely determined by population growth and various demographic variables. Factors such as age, race/ethnicity, household size, occupation, and income combine to influence the type of housing needed and the ability to afford housing. 1. Population Trends Contra Costa County is the ninth most populous county in California,with its population at approximately 949,000 as of the 2000 Census. This represents an increase of 18% since 1990. Major factors that have contributed to attracting more residents to the County in the 1990s include: the availability of rapid transit; close proximity to major employment centers in Oakland and San Francisco; relatively affordable housing prices in the County; and development of new employment centers along the 1-680 corridor and Tri-Valley area. The Association of Bay Area Governments(ABAG)projects that the County will have 1,021,500 residents by 2005 and 1,076,800 by 2010. While the population of every city in the County increased during the 1990s,population growth has been the strongest in the East County,particularly in Antioch,Brentwood,and Oakley. According to ABAG,East County and San Ramon will account for much of the household growth between 2000 and 2020. (East County includes Antioch,Pittsburg,Brentwood,Bay Point "mom Oakley,and Rural East Contra Costa County. The San Ramon Valley includes the unincorporated community of Dougherty Valley.) Substantial growth is also expected in Bay Point an unincorporated community within Pittsburg's sphere of influence, as the Pittsburg/Bay Point BART(Bay Area Rapid Transit)station is the new terminus for the Bay Point/Pittsburg line. ABAG is also anticipating noticeable growth for the West County, especially for the cities of Richmond and Hercules. Redevelopable land near the new Richmond Parkway connecting 1-80 and 1-580 will help fuel growth for the Richmond area. Hercules will most likely grow due to its supply of vacant land and its location at the junction of Highways 80 and 4,which is currently under expansion. Central County will continue to absorb new housing growth,despite the diminishing supply of vacant land. Undeveloped land remains available in pockets and some communities are experiencing redevelopment in neighborhoods near the downtown and other activity centers,such as the Walnut Creek and Pleasant Hill BART Stations. In the 2000 Census, the population of unincorporated areas in Contra Costa County was reported at 151,690, representing an increase of 14% since 1990. This level of growth is lower than,that experienced by the County as a whole and by the incorporated cities and towns. However, this trend is partially a result of annexations that had occurred during the past decade,effectively reducing the geographic areas and associated population under the County jurisdiction. ABAG projects that the population of the unincorporated areas will increase to 177,000 by 2005 and to 185,900 by 2010. In Table 6-1,the population of unincorporated areas in the County by region(sub-area)is shown. Table 6-1 Poeulation Growth Trends Jurisdiction 1990 2000 Numeric Change %Change Unincorporated Sub-Areas East 391,438 41,891 2,453 +6% Central 50,1134 64.1920 141,786 +29% West 43,492 44,879 1.1387 +3% Total Unincorporated* 133,064 151,690 18.)626 +14% Cities and Towns 6701,668 797,126 126,1458 +19% Total County 803,732 948,1816 145,1084 +18% Sources: 1990,2000 Census. *Excludes Oakley both in 1990 and 2000—Oakley incorporated in 1999. The Central region had the largest population of the three unincorporated sub-areas in both 1990 and 2000. During the 1990s, the population of this sub-area increased significantly (29%), from 50,134 in 1990 to 64,920 in 2000. In contrast,the East and West regions grew by only 6%and 3%,respectively. As of 2000,the East and West regions had a population of 41,891 and 44,879, respectively. Specifically,unincorporated communities that are census-designated places(CDPs)which grew most dramatically in the 1990s include Blackhawk(62%)and Discovery Bay(68%). -MONO 2. Age Characteristics A community's current and future housing needs are determined in part by the age characteristics of residents. Typically, each age group has distinct lifestyles, family type and size, incomes, and housing preferences. As people move through each stage of life, their housing need and preferences also change. As a result, evaluating the age characteristics of a community is important in determining the housing needs of residents. 6-6 6. Housing Element Table 6-2 provides the age characteristics of residents in the unincorporated areas and the County as a whole in 1990. As shown, the age composition of unincorporated area residents was very similar to that Countywide. According to the 1990 Census, the largest age group in the unincorporated areas was young adults at 34%,followed by middle age residents at 22%,the school age population at 17%,and seniors at 11%. Table 6-2 Age Characteristics Age Groups Unincorporated County Total County Persons Percent Persons Percent Preschool(Ag s<4) 9.)469 7% 60,743 8% School Age(5-17) 23,1005 17% 141,345 18% College Age(18-24) 11.)390 9% 721,259 9% Your Adults(25-44) 45.)421 34% 282,171 35% Middle Age(45-64) 29.)577 22% 159,1718 20% Senior Adults(65+) 14?202 11% 87,496 11% Total 13,31,064 100% 803,732 100% Source: 1990 Census(2000 Census data not available). *Excludes Oakley both in 1990 and 2000—Oakley incorporated in 1999. A high proportion of young adults generally indicates a need for rental units and first-time homebuyer or first move- up opportunities, including condominiums, town homes, or single-family homes. Middle age residents typically occupy larger homes and are usually at the peak of their earning power. Senior residents in Contra Costa County are mostly homeowners and typically occupy single-family homes. Nationwide trends, however, indicate that as the baby boom generation ages, the demand for move-down housing or specialized residential developments, such as assisted living facilities or active adult communities will grow. Complete age data from the 2000 Census have not been released by the Census Bureau. However, preliminary Census data indicate that 112,077 unincorporated County residents were age 18 years and above in 2000,representing an increase of 11%since 1990. Between 1990 and 2000,the number of persons under 18 in the unincorporated areas grew by 22%; their share of the total population increased from 24% to 26%. The growth of this segment of the population suggests a corresponding growth in the number of young adults and middle age persons. Preliminary Census data also indicate significant differences in the age distribution among the various communities in the unincorporated areas. Several communities have a median age well above 40, including Bethel Island(48.5), Kensington (47.1). Diablo (45.8), Port Cost (45.7), and Alamo (43). Communities with a lower median age, signifying a younger population, include Bay Point (29.1), Rollingwood (29.9), and Byron (30.5). In general, communities in the Western sub-region have a higher median age than the central and eastern sub-regions. 3. Race and Ethnicity The San Francisco Bay Area, including Contra Costa County, has been """.7 changing in the racial and ethnic composition of its population. These changes may have implications for housing needs to the extent the groups typically have different household characteristics, income levels, and cultural background that may affect their wed and references for housing. Recent studies have also suggested that different race lethtfic groups differ in their attitudes toward mid/or tolerance for"housing problems"as defined by the federal Department of Housing and Urban Development(HUD), including overcrowding and housing cost burden? According to these studies,the perceptions regWing housing density and overcrowding,as well as cultural practices of living with extended milies,tend to vary among ditfert'nt racial/ethnic groups. The population of unincorporated areas in Contra Costa County has become more diverse in recent decades. As of 2000,white residents comprised the largest racrJethnic group in the unincorporated County areas, as they were in 1990 (Table 6-3). However, the share of white population declined from 75% to 63% during the 1990s, wWe the other race/ethnic groups, especially Hispanics, grew noticeably in size and proportion. The number of Hispanic residents increased by 84%and their share of the total population grew from 10%to 17%. The number of Asian and Black residents also expanded,by 49%and 22%, respectively. The number of residents in the"All Other"category grew dramatically, largely because the 2000 Census allowed people to identify themselves as members of more than one racial group. The"All Other"category includes American Indians and Alaska Natives, and persons who identified "Some other race' and "Two or more races." As the County population becomes'increasing diverse,different types of housing should be provided to accommodate the diverse needs. Such studies include the following:"The Deterrninants of Household Overcrowding mid the Role of Immigration in Southern California"by S.Y. Choi (1993); "I"he Changing Problem of Overcrowding"by D. Myers,William Baer, and S.Y. Choi (1996);and"migration Cohorts and Residential Overcrowding in Southern California"by D.Myers and S.W.Lee(1996). 6-7 6.

The race/ethnic composition of residents varies significantly by location in the County. According to preliminary data from the 2000 Census, approximately 80%of residents of the unincorporated communities(Census designated places or CDPs)in the Central sub-region are White,compared to 51%and 52%for the East and West sub-regions. Conversely, the Hispanic share of population is noticeably higher in the East and West sub-region (29%and 19% respectively) than in the Central sub-region (7%). Also noteworthy is that Asian and Black residents comprise a greater portion of the population in the West sub-region(13%and 11%)than in other areas of the County. Specifically, four CDPs have significant proportions of Hispanic residents—Bay Point (39%), Bayview-MontavIin (31%),Tara Hills(21%)and Vine Hill(20%). Six CDPs have relatively significant proportions of Black residents— East Richmond Heights(14%),Rodeo(14%),Tara Hills(13%),Bay Point(12%),El Sobrante(10%),and Bayview- Montalvin Manor (10%). North Richmond is also known to have a concentrated Black population. Some CDPs with relatively high proportions of Asians include Rodeo (17%), Blackhawk-Camino Tassajara (17%), Tara Hills (15%),Bayview-Montalvin Manor(13%),and Bay Point(11%). Therefore,Bay Point,Bayview Montalvin Manor and Tara Hills represent the most ethnically diverse communities in the unincorporated areas. 4. Employment Employment has an important impact on housing needs. Different jobs and income levels determine the type and size of housing a household can afford. Employment growth in the region also typically results in an increase in housing demand, particularly in areas that fiuiction as a"bedroom conununity." Based on the 1990 Census,a total of 430,746 Contra Costa County residents were in the labor force, with the unemploynwnt rate estimated at 5%. According to the State Employment Development Department,the unemployment rate in the County was 2.7%in 2000.

Table 6-4 shows the types of occupations held by residents in unincorporated areas and the County as a whole. As of 1990,the two largest occupational categories were ft . and sales/technical/adrninistrati - These categories accounted for 33% and 32%of employed residents in the County's unincorporated ams, respectively. Relatively how paying jobs are in both categoiies,except for certain sales positioris,translating into higher incomes for the residents engaged in these activities. Contra Costa County has one of the fastest growing work forces among Bay Area counties, with growth in its employment base driven primarily by the need to provide services to an increasing local population. The number of white-collar jobs has also increased in the County due to the decentralization of office-related employment to the County from other parts of the region,particularly San Francisco. Now 6-8 6. Housing Element Major industries in the County include petroleum refining, telecommunications, retail and financial services, steel manufacturing, prefabricated metals, chemicals, electronic equipment, paper products and food processing. Table 6-5 identifies the major employers in Contra Costa County,which includes firms and businesses in a variety of industries. ABAG anticipates that Contra Costa County will add approximately 69,400 new jobs between 2000 and 2010. About half(51%) of this growth will be in the services sector, which will add 35,330 jobs (an increase of 27%) during the ten-year period. Other sectors that will grow noticeably over the ten-year period are the high technology, and transportation, communication, and utilities sectors. Specifically, the number of jobs in the high technology industry is projected to increase by 43%, from 6,370 to 9,130. The number of jobs in the transportation, communication,and utilities will grow by 30%,from 25,180 to 32,730.

Most manufacturing and wholesale trade jobs will be captured by Oakley,Richmond,and Pittsburg. Antioch, San Ramon, and Brentwood will experience the highest growth in retail employment. Growth in service jobs will be concentrated in San Ramon,Concord,and Richmond. The County has traditionally supported a number of"bedroom communities"for the work force of other Bay Area counties. ABAG expects this situation to continue, indicating the County will add nearly 23,000 more employed residents than jobs between 2000 and 2020. B. Household Characteristics Household vAx and size,*income levels,the presence of special needs populations,and other household characteristics UUMUTUM the qW of housing needed by residents. This section details the various household cbarxtefisfics affecting housing needs. 1. Household Type The Census defines a"household" as any group of people occupying a housing unit which may include single persons living alone, families related through marriage or blood, or unrelated persons sharing living quarters. Persons living in retirement or convalescent homes,dormitories,or other group living situations are not considered households. Household characteristics are important indicators of the type and size of housing needed in a community. The State Dqwtment of Finance estimates that 61,863 households lived in the unincorporated areas of Contra Costa County in 2000. The distribution of these households by type can be infwed from the 1990 Census since household data from the 2000 Census are not yet available. As shown in Table 6-6,the majority of households in the unincorporated areas are fitmilies,(73%). Single persons comprise 20%of households,while 7%of households were unrelated persons living together("Offiee). 4 Rural East Contra Costa County includes Discovery Bay, Bethel Island, Byron, Knightsen, and other small rural communities in the eastern part of the County. 6-9 6.

Housing need generally varies by household type. Families typically occupy single-family homes. (Approximately 80%of the housing stock in unincowated areas are single-family dwellings.) However,because of the relatively high costs of most single- f unily homes,some fimiffies,live in aptrur or condominium,units,which tend to be more affordable. Subsidized housing for lower-income families are �y available the Housing Authority of Contra Costa County and non-profit housing providers. Of the 1,149 go t assisted housing units in orated areas,909 units are for families. Single peons typify occupy smaller ap t units or condominiums,such as studios and one-bedroom units. Singlo-Pemon households may include seniors living alone,young single adults,and other individuals. 2. Household Income Table 6-7 Income is the most factor agog the Median Household Income Unincorporated Areas housing opportunities available to a household, Census Median Household the ability to balance housing costs with Designated Income as%of other basic necessities of life.

Based on projections by ABAG, the mean household income of Contra Costa County residents in 2000 was $79,000, which was the fourth highest among the nine counties of the San Francisco Bay Areas Only Marin, San Mateo,and Santa Clara counties had a higher mean household income than Contra Costa County. Income level varies significantly by location in Contra Costa County. As shown in Table 6-7, Alamo and Blackhawk in Central County are very high-income areas, with their respective household incomes more than double the County median in 1989. Discovery Bay and Kensington also had higher median household incomes than the County as a whole. Lower- income unincorporated areas include Bay Point, Bethel Island, and Pacheco. All three communities had a median income of less than 80% of the County median. Not surprisingly, these } communities also have a relatively high concentration of lower-income households based on HUD data. North Richmond and portions of El Sobrante are also known to have a high proportion of very low-income households. 5 In 1995 Dollars 6-10 6. Housing Element According to ABAG, the 2000 mean household income of residents in the unincorporated areas ranged from$61,500 in Rodeo-Crockett to $177,900 in Alamo-Blackhawk. Rural East County,which includes Sand Hill,Discovery Bay,Bethel Island,and other small rural communities in the eastern part of the County,had a mean household income of$80,600. Table 6-8 provides the income distribution of households living in unincorporated areas in 1990 and 1999. As indicated, 42% of all households in the unincorporated areas in 1999 earned upper incomes (above 120% of the County median family income or MFI). Approximately 26%of households were in the moderate-income range(81 to 120%of MFI)and 32%were in the lower(80%or less of MFI)income categories.

Special Needs Groups Certain groups have greater difficulty in finding decent affordable housing due to their special needs and/or circumstances. Special circumstances may be related to one's employment and income, family characteristics,disability, and household characteristics, among others. As a result, certain segments of residents in Contra Costa County may experience a higher prevalence of lower income,housing cost burden,overcrowding,or other housing problems. "Special needs" groups include the following: senior households, mentally and physically disabled persons, large households,single-parent households(female-headed households with children in particular),homeless persons,and agricultural workers. This section provides a detailed discussion of the housing needs facing each particular group as well as programs and services available to address their housing needs. Determining the housing issues of special need groups is easier than definning the magnitude. Because detailed data from the 2000 Census is not available as of this writing, the 1990 Census is used to estimate the size of a particular group. Recent information from service providers and government agencies is used to supplement the 1990 data. Table 6-9 the special needs groups residing in unincorporated areas of the County(excluding Oakley).

Senior Households Senior households have special housing needs primarily due to three major concerns -physical disabilities/limitations, income,and health care costs. According to the 1990 Census, 18%(8,893)of households in the unincorporated areas of 6-11 6. Housing Element Contra Costa County were headed by seniors, defined as persons 65 years and older. Countywide, there were 54,825 OWNS* elderly households. Some of the special needs of seniors are as follows: > Limited Income-Many seniors have limited incotne available for health and other expenses. Because of their refired in .6 status,one out of two elderly households(50%)1 Contra Costa County earns extremely low or very low-income > Disabilities-Of the senior population Countywide,one-third have a work disability and/or self-care or mobility limitation. > Cost Burden-Because of the limited supply of affordable housing and their limited*income,28%of senior 7 households in the County experience housing cost burden. The prevalence of housing cost burden varies "Now significantly by tenure:20%of homeowners and 62%of renters. Over 80%of elderly households(7,404) in the unincorporated areas were homeowners in 1990. Because of physical and/or other limitations, senior homeowners may have difficulty in carrying out regular home maintenance or repair activities. Elderly women are especially likely to be in need of assistance due to their physical and/or other limitations. Various programs can address the special needs of seniors, including but not limited to congregate care, supportive services, rental subsidies, shared housing, and housing rehabilitation assistance. For the frail elderly, or those with 1� disabilities, housing with architectural design features that accommodate disabilities can help ensure continued independent living. Elderly with mobility/self-care limitations also benefit from transportation alternatives. Senior housing with supportive services can be provided for those who require assistance with daily living.

Disabled Persons Physical, mental, and/or developmental disabilities may prevent a person from working, restrict one's mobility, or make it difficult to care for oneself. Thus, disabled persons often have special housing needs related to potentially limited earning capacity, the lack of accessible and affordable housing, and higher health costs associated with a disability. Some residents suffer from disabilities that require living in a supportive or institutional setting. The 1990 Census defines three types of disabilities: work,mobility, and self-care limitations. Disabilities are defined as mental,physical or health conditions that last over six months. The Census tracks the following disabilities: ✓ Work disability-Refers to a condition lasting over six months which restricts a person's choice of work and prevents that person from working full-time. ✓ Mobility limitation - Refers to a physical or mental condition lasting over six months that makes it difficult for a person to go outside the home alone.✓ NOW" Self-care limitation - Refers to a physical or mental condition lasting over six months that makes it difficult to take care of one's personal needs. According to the Census,a total of 13,087 persons with disability resided in the unincorporated County areas,representing venom approximately 13%of the population 16 years of age or old. About 54%of these residents face work disability., 19%have mobility/self-care limitations,and the rerrtain. 27%have both work disabilities and mobility/self-care limitations. In 1999, an estimated 66,000 persons (16years and above)Countywide had some form of disability related to work, mobility, or self-care limitations. The Regional Center of the East Bay estimated in 2000 that there were over 3,000 individuals in the County with developmental disabilities. Persons with developmental disabilities may have communication and learning disorders,and may lack basic life skills. In addition.,between 8,,000 and 17,000+mentally disabled persons are estimated to be living in the County(Contra Costa Consortium 2000-2005 Consolidated Plan). The County's mental health system serves approximately 7,200 mentally disabled adults annually. The living arrangement of disabled persons depends on the severity of the disability. Many live at home independently or with other family inembers. To maintainindependent living,disabled persons may need assistance. This can include special housing design features for the disabled, income support for those who are unable to work,and in-home supportive services for persons with medical conditions among others. Services are typically provided by both public and private agencies. AWWft As shown in Table 6-10, 114 licensed community care facilities are located in the unincorporated areas, including 2 small family homes, 12 group homes, 26 adult residential facilities, and 74 elderly residential facilities. The OWMW 6 Extimiely low is defined as below 30%of area median family incorne. Very low is between 30%and 50%of area median family income. 7 Lower-and moderate-income households that spend more than 30%of their incomes on housing costs(including mortgage or am rent,utilities,taxes,and insurance)are typically considered as overpaying for housing,experience a housing cost burden. 6-12 6. Housing Element majority (74) of care facilities are for the elderly, reflecting the special needs of senior residents, especially those with disabilities. Of the 672 beds available in elderly care facilities,54 are for seniors suffering from dementia.8 . Independent Living Resource(111R),an area non-profit organization,provides information and referral,attendant referral,advocacy., housing assistance, and peer counseling services for persons with disabilities. ILR also offers advocacy services, which aim to maintain or increase access to services,benefits,and odw social services and advises clients regarding their rights under Section 504 of the federal Rehabilitation Act of 1972 for disabled individuals. RR's housing referral services assist clients by ;*1;*%r1 a adaptable, of accessible, affordable agpartrr s and houses,information on how to adapt a living environment to a disabled individuals needs,and assistance with obtaining a low income housing subsidy. ILR has offices in Antioch,Concord,and Richmond. Transportation service for paww with disabilities is available through County Connection Link made available by the Central Contra Costa Transit Authority. Under this--- door-to-dom.)dial-a-ride para-transit services are offered to individuals with disabilities. Transportation services are also provided by East and West County Para-transit,WestCat and Tri-Delta Transit Services.

Single-Parent Households Because of their relatively lower hxxmws and higher living expenses,singk1mrent households we more likely to have difficulty finding affordable,decent,and safe housing. These lxx. kls often require special consideration and assis#ance as a result of their greater need for affordable hours*accessible day carel6bildicme,health care,and other st sportive services. Female-headed fiunilies with children are a particularly vuhxrble group because dry nwst balance the needs of their children with work respomibilities. An estimated 3,016 female-headed households with children lived in the unincorporated: areas of the County in 1990, 6%of all households(1990 Census). Countywide,there were a total of 21,215 female-headed households with children,comprising 7%of all households in the County.Within unincorporated areas,approximately 31%of female-headed S to iust arried-couple des with chipupportive families with children lived in poverty in 1990,, 3%of m J-- services for single mothers are available through various non-profit organizations in the County,including the East Bay Perinatal Council,Pregnancy Center of Contra Costa,Mount Diablo Adult Education,and Safe Serenity Home,among others. Battered women with children comprise a sub-group of female-headed households that are especially in need. In Contra Costa County, the largest agency serving battered women is Battered Women's Alternatives, now known as STAND! Against Domestic Violence. STAND! assists over 8,000 battered women in Contra Costa, Solano, and Alarneda counties annually,and offers a variety of services to victim of domestic violence,including a 24-hour crisis line,,a 24-bed emergency shelter,a transitional housing center,legal advocacy,employment assistance,and a batterer's Program. Large Households Large households are defined as those consisting of five or more inerijuets. These households cornnVpnsee a need group, because of the often limited supply of mately affordable housing units in,a community. In order to save for other basic necessities such as food,clothing and medical care,it is common for lower-income large households to reside in smaller units,which 8 Dementia is caused by different illnesses affecting the brain. It may*involve memory loss,and ability to think clearly, to understand words and to recognize people. People with dementia can show personality changes and unusual/distressing behavior. Dementia is rare before the age of 65 and the risk increases with age. 6-13 0". Housing Element frequently results in overcrowding. An estimated 5,069 large households resided in the County unincorporated areas in 1990,28% OWNM (1,430)of which were renter households. Countywide,there were a total of 30,854 large households,of which 31%were renters. The housing needs of large households are typically met through larger units. As of 1990,the unincorporated areas in the County had 27,569 owner-occupied and 3,883 renter-occupied large units(with three or more bedrooms)that could accommodate large households. However,many of these units are single-flinuly homes and are expensive;they are not likely to be occupied by lower-income renter households. Therefore,overcrowding is more prevalent among large renter households. Countywide,51% of large renter households and 19%of large owner households lived in overcrowded conditions in 1990. To address overcrowding,communities can provide motives to facilitate the development of affordable apartrnerrts with three or more bedrooms to meet the needs of large households. Oftentimes,the shortage of large rental units can be alleviated through the provision of affordable owner rJ*housing opportunities,such as condominiums coupled with homeownership assistance and self- help housing(through Habitat for and other sirnilm organizations). Also,Section 8=W assistance provided by the Housing Authority of Contra Costa County(HACCC)can enable large families to rent units they odunvise cannot afford. The HACCC currently manages 447 public housing units for families in the unincorporated areas. With a total of 250 units for families,Bayo Vista in Rodeo is the largest public housing development in the unincorporated areas. Agricultural Workers two^ Agriculture has been an irortannt,but recently declining industry in Contra Costa County. Between 1997 and 1999,the total gross value of agricultural products and crops dropped from $95.2 million to $86.7 million. Approximately 54%of land Countywide is allocated tos m'40 and harvested cropland. (County Department of Agriculture). According to the 1997 Census of Agriculture,587 farms were operating in Contra Costa County,the majority of which were less than 50 acres in size. Agricultural workers we traditionally defined as persons whose primary incomes are earned through permanent or seasonal agricultural labor. Permanent finn laborers work in the fields,processing plants,or support activities on a generally year-round basis. When woddoad increases during harvest periods,the labor force is supplemented by seasonal labor,often supplied by a labor contractor. For some crops,fivrns may employ migrant workers,defined as those whose travel distance to work prevents them from to their primary resideence every evening. Determining the true size of the agricultural labor force is problematic. For the government agencies drat track firm labor do not consistently define (e.g.field laborers versus workers in processing plants),lc*th of employment(e.g.pm,­____t or seasonal),or place of work(e.g.the location of the business or field). According to the 1990 Census, 5,344 persons in Contra Costa County were employed in the fanning, forestry, and fishing occupational category in 1990. Of these persons, 1,529 or 29%were residents in the unincorporated areas. A Statewide study of migrant and seasonal farmworkers completed in 2000 estimated that 2,470 migrant and seasonal farmworkers were working in Contra Costa County(Migrant and Seasonal Farmworker Enumeration Profiles Study-- California, U.S. Department of Health and Human Services, 2000). Based on discussions with various agencies, the County understands that the majority of the fartriworker population in the unincorporated areas consists of resident- saw households requiring permanent affordable housing rather than migratory workers with seasonal housing needs. Fannworkers are generally considered to have special housing needs because of their limited income and the often unstable nature of their employment(i.e.having to move throughout the year from one harvest to the next). While no local survey is available which documents the specific housing needs of farm labor in Contra Costa County,Statewide surveys provide some insight into the demographic characteristics and housing needs of farmworkers. Among the major findings are: ✓ Limited Income-Farmworkers,typically earn very low incomes. According to the Rural Community Assistance Corporation, three-quarters of California's farmworkers earned less than$10,000 a year in 2000. Only one out of seven earned more than$12,500 annually. V Overcrowding-Because of their very low incomes,farmworkers have limited housing options and are often forced to double up to afford rents. A Statewide survey indicates that overcrowding is prevalent and a si cant housing problem among farmworkers(The Parfier Survey,California Institute for Rural Studies,1997). ✓ Substandard Housing Conditions - Many fannworkers live in overcrowded conditions and substandard housing, including informal shacks, illegal garage units, and other structures generally *AM unsuitable for occupancy(The Parlier Survey, 1997). The provision of a equate housing for 6a mmicers and their families is a ns*uW concern is the State. In 1999,the State legislature amended the housing element law to rrraxrdate j'1,'1:1risdic wim address housing for agricultural workers. Under the County's Zoning Code,farm.Labm housing is pwnitted in the agricultural zone districts(A-2,A-3,and A4)subject to a land use permit The County Consortium.Consolidated Plan(2000-2005)indicates that some housing is provided for agricultural workers in County farm er camps,but there is a need for additional housing opportunities for farmworkers and their families. SNOW. To meet the housing needs of farmworkers,the County has provided CDBG and/or HOME fimding for various developments in East County that provide affordable homeownership opportunities for extremely low and very low income households,ince many fi tworker farnilies. These projects include Via de Guadehipe,Najam Estates,Colonia Santa Mar*Marsh Creek Vista,and Arroyo Seco,totaling 241 units. In addition,the County recently approved$1 million in fiscal year 2001/02 HOME Rinds for the 6-14 6. Housing Element Villa Amador project in Brentwood. This project involves the new construction of 91 town home rental units affordable to lower income households. The project sponsor is also applying for State Fmnworker Housing Grant Finds to support the development of the project The County recognizes the imrportarice of providing affordable housing to the fannworker population. The County Agriculture Advisory Task Force has been requested by the Board of Supervisors to develop tions to address the affordable housing needs of farmworkers in Contra Costa. Homeless Persons The 1990 Census documented 47 homeless persons in the unincorporated areas of Contra Costa County and a total of 936 Countywide. Based on current experience, these figures are clearly undercounts. The methodology used in the 1990 Census to count the number of homeless is widely acknowledged as ineffective, thereby resulting in substantial undercounting of the homeless population in many communities,especially larger cities. The Contra Costa Continuum of Care Plan indicates that at least 14,700 people m Contra Costa County experience an episode of homelessness annually, with 4,000 people homeless on any given night. More than three-quarters of them are members of a family,including nearly 7,000 children. On any given night,homeless persons in the County are living on the streets or in temporary accommodations, such as an emergency shelter. Additionally, many others are at risk of becoming homeless,especially very low-income households who are overpaying for housing and struggling to make ends meet. There are three major types of facilities that provide shelter for homeless individuals and families: emergency shelters,transitional housing,and permanent housing.These types of facilities are defined below: ✓ Emergency Shelter-A facility that provides overnight shelter and fulfills a client's basic needs(i.e. food, clothing, medical care) either on-site or through off-site services. The permitted length of stay can vary from one day at a time to three months. There are approximately 490 emergency shelter beds in Contra Costa County, including those reserved for persons with special needs such as the mentally disabled, battered women and their children,recovering substance abusers,and persons with HIV/AIDS. ✓ Transitional Housing-A residence that provides housing for up to two years.Residents of transitional housing are usually connected to supportive services designed to assist the homeless in achieving greater economic independence and a permanent, stable living situation. Services may include substance abuse treatment,mental and physical health care interventions,job training and employment services, individual and group counseling and life skills training. There are approximately 400 transitional housing units in the County. ✓ Permanent Housing-Permanent housing that is affordable in the connnunity or service-enriched permanent housing that is linked with on-going supportive services(on-site or off-sine)and designed to allow fonnerly homeless clients to live at the facility on an indefinite basis. There are approximately 160 permanent supportive housing units in Contra Costa County. Table 6-11 on the following page is a listing of the major housing facilities for the homeless in Contra Costa County. These facilities serve a variety of homeless persons, including battered women and children, mentally and/or physically disabled persons,individuals recovering from substance abuse,and needy families. As a means to help meet the special needs of the hornless,the Contra Costa Crisis Center has establi.sned a 24-Dour homeless hotline that connects homeless individuals and families to resources available in the County. Through the Center,homeless persons are screened for shelters,given emergency motel vouchers,provided free voice mail boxes,and referred to local programs that offer I ansitional .,job training,substance abuse treatment,mental health counseling,ems food,health care,and other services. To more ensively address the issue of hornlessness,the County Health Services Department develops plans and programs to assist the homeless throughout Contra Costa County. Specifically,the Department provides emergency and transitional shelter as well as supportive services designed to enable homeless persons to achieve greater economic independence and a stable living environment The Department coordinates the activities of and provides staffsupport to the Contra Costa Contim m of Care Board (CoC Board),which consists of representatives from local jurisdictions,homeless service providers,advocacy and volunteer groups, the business and faith communities,residents at large,and previously or currently homeless persons. The CoC Board serves in an advisory capacity to the County Board of Supervisors on issues related to homelessness, and participates in the long-range planning and development of strategies to alleviate homelessness m the County. The CoC Board works with the Health Services Department to develop the County's Continuum of Care Plan and annual McKinney Act application,educate the public about homeless issues,and advocate for increased funding for homeless programs. The County Housing Authority also plays an important role in providing shelter to homeless individuals and families. During the 1990s,the Housing Authority acquired and/or rehabilitated major homeless facilities,including the Mountain View transitional housing facility in 1993 and West County Emergency Shelter in 1994. The Housing Authority is currently completing the rehabilitation of the Central County Emergency Shelter. Under the County's Zoning Code, emergency shelters and transitional housing designed to meet the needs of those who are homeless or formerly homeless are permitted in all residential zones subject to a land use permit. In addition, these facilities are allowed in most commercial and industrial districts with a land use permit. (See discussions on the provision of a variety of housing types contained in Section 6.3,Housing Constraints). 6-15 8.Conservation Element 8.3 RELATIONSHIP TO OTHER GENERAL PLAN DOCUMENTS The goals,policies and implementation measures contained in this element are intended to guide planning for public and private projects that are subject either to approval of the County planning agency,or to review by County staff,although they may be under the jurisdiction of other public agencies operating in the County. Such goals, policies and implementation measures are intended to accord and have equal legal status with the other elements of the General Plan. 8.4 CONSERVATION ELEMENT ORGANIZATION This chapter of the General Plan is divided into eight sections that present background information,policies, maps, and implementation measures regarding: 0 vegetation and wildlife,including important trees,natural vegetation,wildlife habitat,significant ecological resources; 0 agricultural resources; 0 renewable energy resources including commercial wind farms,energy recovery and solar projects; 0 mineral resource areas; 0 soil resource areas,including agricultural soils; 0 oil and gas resources; 0 water resources,including urban and rural creeks; 0 harbors; and 0 air resources. 8.5 OVERALL GOALS AND POLICIES REGARDING RESOURCE CONSERVATION The following goals and policies are overall statements regarding the need to preserve and efficiently manage open space and other resources in the County. More detailed policies particular to each type of resource are ,. then discussed under separate topic sections in the remainder of the element. OVERALL CONSERVATION GOALS 8-A. To preserve and protect the ecological resources of the County. 8-B. To conserve the natural resources of the County through control of the direction,extent and timing of urban growth. -- 8-C. To achieve a balance of uses of the County's natural and developed resources to meet the social and economic needs of the County's residents. OVERALL CONSERVATION POLICIES 8-1. Resource utilization and development shall be planned within a framework of maintaining a healthy and attractive environment. 8-2. Areas that are highly suited to prime agricultural production shall be protected and preserved for agriculture and standards for protecting the viability of agricultural land shall be established. -" 8-3. Watersheds,natural waterways, and areas important for the maintenance of natural vegetation and wildlife populations shall be preserved and enhanced. 8-4. Areas designated for open space/agricultural uses shall not be considered as a reserve for urban uses and the 65 percent standard for non-urban uses must not be violated. 8-5. In order to reduce adverse impacts on agricultural and environmental values,and to reduce urban costs to taxpayers, scattered urban development in outlying areas shall be precluded outside the ULL. 8-2 8.Conservation Element 8.6 VEGETATION AND WILDLIFE INTRODUCTION The County has a diverse range of habitats and unique species. Much of the County's natural environment remains while substantial areas have already received permanent public protection. There are additional resources which warrant similar public control. The vast majority of privately held lands supporting vegetation and wildlife resources are found within the agricultural areas of the County. Agriculturalists and biological habitats have co- existed for decades in Contra Costa County;thus privately preserving resources with public benefit. The topographic variety of the County, from the summit of Mount Diablo to the San Francisco Bay/Delta estuary complex, combines to form the setting for its range of habitat and wildlife. In addition to the naturally occurring habitats in the County, suburban communities attract their own assemblage of wildlife. In these areas, the lush shrub and tree plantings of backyard gardens function as a partial substitute for natural scrub and woodland habitats. For example,black-tailed deer occur in gardens and yards during late summer and early fall months. There are unique biotic resources found within Contra Costa County which have biological and wildlife importance. While most of the significant habitat areas are found in unincorporated locations,several important wildlife areas are Within city limits. Wetlands are one of the most important habitat resources within the County. Wetlands,especially marshes scattered along the County's shoreline,have been awarded substantial legal and policy protection. For purposes of this plan,wetlands are lands transitional between terrestrial and aquatic systems where the water table is usually at or near the surface,or the land is covered by shallow water. For purposes of this classification,wetlands must have'one or more of the following attributes: (1) at least periodically, the land supports predominantly hydrophytes;(2)the substrate is predominantly undrained hydric soil;and(3)the substrate is non-soil and is saturated with water or covered by shallow water at some time during the growing season of each year. MAPS AND INVENTORY OF SIGNIFICANT ECOLOGICAL RESOURCE AREAS The most significant ecological resource areas in Contra Costa County are defined by three separate categories: (1 areas containing rare,threatened and endangered species;(2)unique natural areas;and(3)wetlands and marshes. These three categories overlap somewhat,since some of the most significant and unique biological resource areas in Contra Costa County also include habitats for rare, threatened and endangered animal or plant species. The most important unique natural areas in the County-habitats of rare,threatened and endangered species,and wetland areas- are inventoried and briefly described in Table 8-1. The generalized locations of each area are shown on Figure 8-1. The Community Development Dent maintains more detailed maps of these areas in their offices. The animal and plant species that have been designated as" ""endangered,"or"threatened"by eidxx the State of Califom� or the Federal government,and which are known to occur in Contra Costa County are listed in Table 8-2. Inf=moon ' g the known and inferred habitats of some of these rare,threatened and endangered species is included in Figure 8-1. An "endangered species"is one which is in danger of extinction throughout all or a significant portion of its range. A "threatened species"is one which is likely to become an endangered species within the foreseeable future.-k1986C4W%�,a "Vara" fl ft. .. & 1. -JQAA, 4 .. 1 Fet aaw63"A X 4 ffldaed the . , tioon .A The California Environmental Quality Act provides that species which qualify for classification as endangered, threatened or tee-species ul'c;oncers should be protected as such even if they have not been designated under Federal or State endangered species laws. 8-3 1 f •1 7� ?01• f io CIO '�`' F Z N *or�.••• � �a 4 U ...�� J'4 Vii'�•...x ! /, 6` � � 11, Al cc3 r CCS to .�:n d ,•s y.eR � �� /'• ,` b ;w. �'F I ,�1{ max• // , •, f ay •�„ '� r'ti,, f i 0OA- 1 woop t-'•w r..

Data inventoried in the Natural Diversity Data Base is only an indication of the potential for the presence of a protected species. Only field surveys can determine the presence or absence of the species or suitable habitat at any particular site. Some of the unique habitat areas that support Federal or State designated endangered species are already protected by public agencies(e.g.Mt.Diablo State Park and the Antioch Dunes),although many key areas remain under private ownership. r T pilia --A pjA&1tpi-g1 .0 ..

The acquisition of lands in the Vasco Ca-yes area by the �WA ILAAW appw&to ou i • - t :4i ertl,ast:BUy.Regional Park District,and of watershed lands by the Contra Costa Water District,may also aid in the pent protection of some of these resources. To facilitate a better understanding of the unique archeological and natural resources in the southeast County area,a detailed inventory should belxgoEfforts to secure king for such an effort should be explored upon adoption of this plan. Private landowners of ecologically significant resource areas (identified in Figure 8-21) who apply for subdivision or other land use permits shall,unless sufficient information is already available to the County, provide information to the County on the nature and extent of the biotic resources that exist in the area. The County Planning Agency shall be responsible for determining the balance between the multiple uses of the land and the protection of resources. The cumulative impacts on the natural resources from other rural uses such as agriculture, mining, or wind energy, must be examined and addressed as part of the review of applications. Both public and private stewardship of the resources within unique natural areas shall be considered as long as the protection is long term and guaranteed in some manner. Due to the fragile nature of some of these resources,however,public access to the areas should be limited or restricted. The following statements shall guide County elected and appointed officials in making decisions which may affect the ecological resources of Contra Costa County. Note that not all of the biotic areas within the County are discussed here. Goals,policies,and implementation measures regarding riparian corridors vegetation and wildlife along creeks and streams are included in a later section of this element,"Water Resources-Urban and Rural Creeks." VEGETATION AND WILDLIFE GOALS 8-D. To protect ecologically significant lands,wetlands,plant and wildlife habitats. 8-E. To protect rare,threatened and endangered species of fish,wildlife and plants,significant plant communities, and other resources which stand out as unique because of their scarcity,scientific value,aesthetic quality or cultural significance. Attempt to achieve a significant net increase in wetland values and functions within the County over the life of the General Plan. The definition of rare,threatened and endangered includes those definitions provided by the Federal Endangered Species Act,the California Endangered Species Act,the California Native Plant Protection Act and the California Environmental Quality Act. 8-F. To encourage the preservation and restoration of the natural characteristics of the San Francisco Bay/Delta estuary and adjacent lands, and recognize the role of Bay vegetation and water area in maintaining favorable climate,air and water quality,and fisheries and migratory waterfowl. VEGETATION AND WILDLIFE POLICIES 8-6. Significant trees,natural vegetation,and wildlife populations generally shall be preserved. 8-19 8.Conservation Element 8-7. Important wildlife habitats which would be disturbed by major development shall be preserved,and corridors for wildlife migration between undeveloped lands shall be retained. 8-8. Significant ecological resource areas in the County shall be identified and designated for compatible low- intensity land uses.Setback zones shall be established around the resource areas to assist in their protection. 8-9. Areas determined to contain significant ecological resources,particularly those containing endangered species, ` shall bemaintained in their natural state and carefully regulated to the maximum legal extent. Acquisition of the most ecologically sensitive properties within the County by appropriate public agencies shall be encouraged. 8-10. Any development located or proposed within significant ecological resource areas shall ensure that the resource is protected. 8-11. The County shall utilize performance criteria and standards which seek to regulate uses in and adjacent to significant ecological resource areas. 8-12. Natural woodlands shall be preserved to the maximum extent possible in the course of land development. 8-13. The critical ecological and scenic characteristics of rangelands, woodlands, and wildlands shall be recognized and protected. 8-14. Development on hillsides shall be limited to maintain valuable natural vegetation,especially forests and open grasslands,and to control erosion. Development on open hillsides and significant ridgelines throughout the County shall be restricted,and hillsides with a grade of 26 percent or greater shall be protected through implementing zoning measures and other appropriate actions. 8-15. Existing vegetation, both native and non-native, and wildlife habitat areas shall be retained in the major open space areas sufficient for the maintenance of a healthy balance of wildlife populations. 8-16. Native and/or sport fisheries shall be preserved and re-established in the streams within the County wherever possible. 8-17. The ecological value of wetland areas,especially the salt marshes and tidelands of the bay and delta, shall be recognized. Existing wetlands in the County shall be identified and regulated. Restoration of degraded wetland areas shall be encouraged and supported whenever possible. -- 8-18. The filling and dredging of lagoons,estuaries,and bays which eliminate marshes and mud flats shall be allowed only for water-oriented projects which will provide substantial public benefits and for ...., which there are not reasonable alternatives,consistent with State and Federal laws. 8-19. The County shall actively oppose any and all efforts to construct a peripheral canal or any other water diversion system that reduces Delta water flows unless and until it can be conclusively demonstrated that such a system would,in fact, protect, wve and enhance water quality and fisheries of the San Francisco Bay-Delta estuary system. 8-20. Fish,shellfish,and waterfowl management shall be considered the appropriate land use for marshes son" and tidelands,with recreation being allowed as a secondary use in limited locations,consistent with the marshland and tideland preservation policies of the General Plan. 8-21. The planting of native trees and shrubs shall be encouraged in order to preserve the visual integrity of the landscape, provide habitat conditions suitable for native wildlife, and ensure that a maximum number and variety of well-adapted plants are sustained in urban areas. -- 8-20 '�"' 8.Conservation Element 8-22. Applications of toxic pesticides and herbicides shall be kept at a minimum and applied in accordance with the strictest standards designed to conserve all the living resources of the County. The use of biological and other non-toxic controls shall be encouraged. 8-23. Runoff of pollutants and siltation into marsh,and wetland areas from outfalls serving nearby urban development shall be discouraged. Where permitted,development plans shall be designed in such a manner that no such pollutants and siltation will significantly adversely affect the value or function of wetlands. In addition,berms.,gutters,or other strucum should be required at the outer boundary of the buffer zones to divert runoff to sewer systems for transport out of the area. 8-24. The County shall strive to identify and conserve remaining upland habitat areas which are adjacent to wetlands and are critical to the survival and nesting of wetland species. 8-25. The County shall protect marshes.,wetlands,and riparian corridors from the effects of potential industrial spills. 8-26. The environmental impacts of using poisons to control ground squirrel populations in grasslands shall be thoroughly evaluated by the County. 8-27. Seasonal wetlands in grassland areas of the County shall be identified and protected. 8-28. _fforts shall be made to identify and protect the County's mature native oak,bay,and buckeye trees. 8 28.1.

The following other uncommon or protected species which occur or may occur in the County should also be included in the list: plant species which are included in the California Native Plant Society's Inventory of Rare and Endangered Vascular Plants of California,species of special concern as designated by CDFG, and California Fully Protected animals as defined by California Fish and Game Code. In addition to making updates as new information becomes available,the list should be reviewed at least once every two years for adequacy. 8-c In cooperation with other public and private agencies, prepare a detailed inventory of biological and archeological resources in the Southeast County area,to be used in project review. Develop ent Review Process 8-d Update and maintain detailed maps of the significant ecological resource areas described in Implementation 8-a above,and use them in the environmental review process to determine potential impacts upon these resources. 8-e Prior to the approval of discretionary permits involving parcels within a significant ecological resource area as described in Implementation Measure 8-a,the County shall require a biotic resources evaluation 8-21 8.Conservation Element based upon field reconnaissance performed at the appropriate time of year to determine the presence or absence of rare,threatened or endangered species of plants or animals. Such evaluation will consider the potential for significant impact on these resources,and measures proposed to mitigate such impacts,where feasible,or indicate why mitigation if not feasible. 8-f Prepare a list of standard mitigation measures from which the County could select appropriate measures to mitigate the impacts of projects in or adjacent to significant ecological resource areas. M00% 8-g Require the environmental impact analysis of all significant grassland land sites proposed for development to include an early spring site reconnaissance to determine the presence of vernal pools and rare species associated with vernal pools,and document the use of any seasonal wetlands by water bird species. A general observation of such sites during the dry portion of the year shall be deemed insufficient for environmental review. Significant grasslands include generally parcels of more than 40 acres which are located in an area dominated by native or introduced grass species. 8-h Amend the ordinance to require developers to pay mitigation costs according to an adopted schedule,such as requiring,where appropriate,and to the extent legally permissible,that three new trees be planted for every 40- one mature tree removed as part of a development. Replacement trees should be the same or a similar species as the tree removed,and should be native species or naturalized species which are well-adapted to the site's conditions without posing a threat of invasion into surrounding lands. 8-i Amend the ordinance to prohibit damage to heritage trees by soil compaction,grading,filling or alteration of drainage patterns beneath the root zones of heritage trees during construction. Watering programs for lawns and gardens in new subdivisions should be designed to prevent soil saturation around the root zones Ameaft of oak trees during the summer months to avoid infection by oak root fungus. Wetland Areas 8-j A setback the edge of any wetland area maybe required for any new structure. The breadth of any such setback shall be determined by the County after environmental review examining(a)the size and habitatValueofthepolentiall:y affected wetland,and(b)potential impacts on the wetland,and adjacent uplands,arising out of the development and operation ofdx new structure. Unless enviruunental review indicates that greater or lesser protection is necessary or ,fie,setbacks generally will be between 50 and 100 feet in breadth. Expansions or other modifications of non- habitable agria*mIly-related struchm existing as of 1990 be exempt from this setback Parcels 0% which would be re-mhzed unbuddable by application of this " shall also be exempt. 8-k Permit minor landfill (less than one acre) or other land reclamation for water-oriented uses only if a AMNON finding has been adopted by the planning body that verifies no alternative site is available,and if public benefits clearly exceed public detriments from the loss of open water or tidelands areas. 8-1 The County shall require avoidance,minimization and/or compensatory mitigation techniques to be employed with respect to specific development projects having a potential to affect a wetland. In evaluating the level of compensation to be required with respect to any given project,(a)on-site mitigation shall be preferred to off-site and in-kind mitigation shall be preferred to out-of-kind,(b)functional replacement ratios may vary to the extent necessary to incorporate a margin of safety reflecting the expected degree of success associated with the mitigation plan,and 0 acreage replacement ratios may vary depending on the relative functions and values of those wetlands being lost and those being supplied. Agnew To the extent permitted by law,the County may require 3:1 con4xnwtoryMAR,gation of any project affecting a "Significant Wetland". 8-m Urge the appropriate State and federal agencies to implement a rigid and frequent inspection system of all industrial facilities along the shoreline which have the potential of creating hazardous spills. 8-22 8.Conservation Element k 8-n Adopt an emergency response plan which outlines how to ensure the swift construction of floating oil slick barriers at the mouths of all slough and creek channel inlets along the County's shoreline areas,in the event of an oil or other hazardous material spill.

Proper planting and maintenance techniques are necessary to ensure the long term survival of newly establish oaks. 8.7 AGRICULTURAL RESOURCES INTRODUCTION The following section presents background data on the relative importance of the County's agricultural resources. The analysis is based upon economic performance indicators, and *indicates that agricultural resources in the County represent a significant economic asset. The dominant trend in local agriculture in Contra Costa County since 1940 has been a significant decrease in the amount of acreage in production. Much of this decline is attributable to the'increasing urbanization of the region,a process which over time gradually converts agricultural lands to housing and other urban uses. In Contra Costa County,land in all types of active agricultural uses(cropland and grazing lands)has declined.bvy 14-Ail"IfLi AA 01m&AA Blvtwo&41 COCOMW Ok-laeras ila&1A 9_0 1 41 QNX E=FA-2.9 51 I 4hed2&Vinu& ArVAR'l tE) t 6 rMan-ga"t af All 'Ang4b;633AQ� 'W-1%-1%4AJMJ%.J1 A U"-No"f&%.Y abiies-L -A.,,..,..0 E.Kems.if)I WW WA LAJA N—A.7"14w..T Table 8-3 includes a general summary of changes in acreage devoted to the major types of agricultural production in Contra Costa County since 1940. It should be noted that range and pasture lands,which provide gazing for large farm animals and dry fanning of grains for feed,have historically accounted for a large portion of total agricultural acreage in the County. These lands include all areas with steep slopes,rugged terrain,a lack of adequate water supply,or other natural constraints which make the land unsuitable for more intensive agricultural activities. In 1940,two-thirds of all agricultural lands in the County were in this rangelands category,by 1990 2000 rangeland accounted for83-84 percent of all agricultural acreage,primarily due to the decline in other intensive fanning techniques. 8-23 8.Conservation Element ..

In Contra Costa County,minor subdivisions of farming properties are often requested so that a member of the family can build an additional home on the property. Banks require collateral for construction loans; few landowners wish to risk the entire holding,or a large portion of it, as security for a construction loan. Minor subdivisions are also requested when a farming family wishes to sell of a small piece of their land in order to make up a shortfall on the remaining operation. While the limited subdivision of agricultural lands for legitimate reasons should be accommodated by the County, ` it is apparent that allowing a proliferation of land divisions in a given area will have a disastrous effect on other farmers or ranchers who are trying to remain in business. The proliferation of minor subdivisions has the effect of creating smaller and smaller parcels of land in agricultural areas,with more and more"ranchette"units owned by non-farming families moving into the area and bidding up the price of the land, which in turn drives out the original farmers. Adequate minimum parcel sizes in agricultural zones must be maintained in order to protect the existing farm operations and to discourage urban landowners from building homes in the area. �- Vere are a number of standards and implementation policies which the County can choose From in protecting the economic viability of agricultural land. One opportunity for assisting the farm or ranch operation to remain in business is M-- the concept of"transfer or purchase of development credits"(TDR/PDR). Transfer or purchase of development credits is a method of preserving agricultural and other open space lands by providing the owner with compensation either by providing cash payments for a property's urban development potential or by crediting and transferring this potential to ..� another property. In this way,the agricultural landowner reaps the benefit of agricultural land development potential without the negative effect that construction and occupation of homes on these lands can bring. I_ Other strategies for the continued viability of agricultural pursuits include preservation agreements with the County,granting conservation easements,direct purchase,leasebacks,tax benefits for agriculture or open space 8-2b 8.Conservation Element land,purchase or transfer of development rights,clustering development,establishment of an agricultural soils trust fund, and agricultural mitigation fees or land dedication(in-lieu fee). During the 3.0,17(11"143714 102 kJ1%AA&%.& a�... last few decades,the County has seen the growth of"ranchett&'style housing. These homes appeal to people with urban incomes who wish to pay extra to live in the more rural,hilly parts of the county and are typically located on large lots(five acres or more). Many of these property owners are small time farmers,while some of the demand is from residents who own horses and wish to stable them near their homes. Ranchcttes are also occupied by retired ranchers or farmers who do not wish to leave the area,but no longer work the land. The policies Of the Contra Costa County Board of Supervisors regarding ranchettes is contained in a 1983 resolution of the Board(No. 83/407)entitled"Rural Residential Development." The policy states that ranchettes created by such parcelization are inappropriate in prime agricultural areas where active cultivation such as row crops or orchards are present. Furthermore,the policy states ranchettes are to be discouraged within city spheres of influence. This General Plan incorporates the Rural Residential Development policy as it relates to subdivisions of lands planned for agricultural uses. The plan specifically discourages major subdivisions in agricultural areas. However, if major subdivision occurs, the plan requires rezoning of the project area to the Planned Unit Development District,with the property owner required to deed further development rights to the County in order to mitigate the impact of development of the lands. The Plan also incorporates an Urban Limit Line. Reflecting Measure C-1990,for prime productive agricultural lands(Class I and H Soils based on the SCS Capability Classification)outside the Urban Limit Line,a minimum parcel size is determined to be 40 acres. One factor and criteria for determining whether land should be located outside the ULL is also related to the preservation of economically viable agricultural land. Land which qualifies for rating as Class I and Class H in the Soil Conservation Service Land Use Capability Classification is one of the factors to be considered in establishing the ULL. Rural residential and certain agricultural structures(allowed by applicable zoning)are included within the 65 percent non-urban uses in the 65/35 Land Preservation Standard. Agricultural lands within the Urban Limit Line would have variable sizes. MAPS AND INVENTORY OF AGRICULTURAL RESOURCE AREAS Figure 8-2 illustrates the most important agricultural lands found in the County. This figure indicates that there are important grazing lands found in the Briones,Hills,Bollinger Canyon,Tassajara,and other areas,while the most important orchard and row crops are located in the East County area. While there are some public lands in the County(e.g.,watershed lands owned by the East Bay Municipal Utility District(EBMUD))that allow the grazing of livestock,these lands are not generally included on the Figure 8-2 map,since grazing is not the primary activity. The use of EBMUD lands,as well as regional or State park lands, for grazing may be discontinued in the future. The agricultural preservation policies found in this section focus on these remaining important grazing,orchard, and row crop areas in the County. AGRICULTURAL RESOURCES GOALS 8-G. To encourage and enhance agriculture, and to maintain and promote a healthy and competitive agricultural economy. 8-H. To conserve prime productive agricultural land outside the Urban Limit Line exclusively for agriculture. 84. To minimize conflicts between agricultural and urban uses. 8-J. To encourage cooperation between the County and cities in the preservation of agricultural lands. 8-27 a h • Y ,R .r N p ENO so ' O ui IC QK vi Inn Wcr Z ' ate• b Z t^ 06 Ki V' r y TT t: t A 7 3 t t 4Y 1 OG F k Q, h k a r� Q Cd Aw O 1 -� x t . 5 c r ` a.:' •� Z lJ { r ... r ..ww VI r■.w + � • b � to d N J03 Y dr...1 O ti O N V W.

(2) Agricultural/Open Space subdivisions are considered a long-term,rural/residential use of the land. Parcel size shall be a minimum of 5 acres in lands designated Agricultural Lands and 20 Acres in lands designated Delta Recreation and 40 acres in lands designated prime productive agricultural lands. (3) Any application for parcels to be separated from a larger parcel or parcels under the same ownership shall indicate on the plan all of the contiguous land held by the applicant. (4) Prior to the filing of the Final or Parcel Map the applicant must comply with the following: (a) Each parcel must have an"on site"producing water well or install a"test well" -- having a minimum yield of three gallons per minute with bacterial and chemical quality in compliance with the State standards for a pure,wholesome and potable water supply(Title 22,Section 64433). If the chemical analysis exceeds the State -- standards for "maximum contaminant levels" for water potability, a statement must be attached and"run with the deed"advising of these levels;or (b) Have verifiable water availability data from adjacent parcels presented by the applicant,or knowledge of the same,known by the Health Services Department concerning water quality and quantity per(a)above;and,have a statement that "attaches and runs with the deed"indicating that a water well shall be installed on the subject parcel complying with the general requirements stated above prior to obtaining a Building Inspection Department permit for construction. (c) In addition to the above,a by drogeological evaluation may be required in known or sued water short areas.This will include seasonal as well as yearly variations. (d) The purpose for requesting hydrogeological evaluations is to determine the total projected number of dwelling units that can be supplied with drinking water from existing aquifers. The two primary circumstances that would generally require hydrogaological evaluations are: (i. where aproposed major subdivision contemplatingthe addition of large numbers of dwelling units on individual wells would mbstantiallyincrease the densitywithin an mono existing drainage basin.Hydrogeological data relevant to recharge of aquifers and projected yield would become essential not only to support approval of large major 8-30 MOW 8.Conservation Element subdivisions under these circumstances,but also to ensure that the water supplies serving existing structures would not be depleted bythe proposed increase demand (ii. In those cases where density is increasing in particular drainage basins due to the buildout of previously approved subdivisions using individual wells for water supplies,existing well yields begin to evidence declines due to the increased demand or in water short basins,hydrogeological studies would be appropriate as conditions of approval of subsequent development to provide sufficient yield for proposed uses.Specific reasons will be stated in support of requested hydrogeological evaluations in each case. (6) Road,street and access requirements,including necessary right-of-way acquisition and/or dedications,will be subject to the Department of Public Works recommendations for each parcel in accordance with the County Subdivision Ordinance and with standards and policies of that department. (7) The land must be suitable for septic tank use according to the County Ordinance Code criteria and Health Services Department Regulations. Percolation tests must be passed on all lots prior to the filing of the Parcel or Final Map. (8) The applicant shall indicate on the Tentative Subdivision Map the following information for each parcel: proposed driveways,building site,well site,leach field site,provision for water storage for fire fighting. Homesites shall be designed with a minimum of grading. Where significant grading is needed and acceptable erosion control plan shall be provided with the application. Home siting shall be reviewed for energy conservation features(building site orientation and feasibility for solar facilities will be considered). (9) Parcels shall be reasonable free of hazards, including,but not limited to flooding and high landsliding susceptibility. (10) Special detailed plans may be required for provision of flood control,roads and other services. (11) Developer shall obtain requirements for road and flood control improvements from County Public Works Department prior to submitting an application for subdivision. Required improvements shall be included on the Tentative Subdivision Map. (12) Adequate fencing shall be provided to contain domestic animals on the residential parcels with all gates to be closeable by a nearby rancher/farmer when necessary. (13) Exception to any of the above Rural Residential Ranchette criteria may be considered by the hearing body upon a showing, in writing, of unique or unusual circumstances relative to the subject property. Development Review Process 8-w Within the major resource conservation areas, consider approval of development that is only directly related to agricultural production,recreation,water-related recreation,or the utilization of mineral,soil, water, and animal resources; or agricultural/residential uses of similar character. 8-x Discourage applications for major subdivisions of agricultural lands. Where such applications are accepted for processing,require concurrent application for rezoning of such lands to the Planned Unit Development District. Require deed of development rights to prevent further subdivision when so doing is consistent with law. 8-31 8.Conservation Element 8-y Identify and map those properties that include prime productive agricultural soils(Class I and H capability according to the U.S.Soil Conservation Service)for use in the review of development applications and evaluating the ULL. Zoning Ordinance Revisions 8-z Modify the agricultural zoning districts to allow agricultural service businesses and uses in agriculturally designated areas as follows: (1) Small agricultural service businesses, which can be defined as a home occupation, are permissible in all agricultural designations; (2) Larger agricultural service businesses which have more than one employee but are clearly subordinate to on-site production activities,and which occupy less than%acre of land and do not adversely affect agricultural production in the area, may be permissible in all agricultural designations,subject to issuance of a land use permit; (3) Agricultural service businesses that occupy more than 1/2 acre of land and are not subordinate to on-site production activities will require rezoning with a "Agricultural Service Combining District"overlay. 8-aa Agricultural employee housing may be permitted, in addition to the residential density allowed by the underlying zoning or land use designation, in accordance with the needs of the local production sector. Criteria to establish the specific conditions which will apply to the agricultural employee housing shall be included in the Zoning Ordinance and shall address permanent and transient employees. 8-ab. Review and revise,as necessary,minimum lot size standards in agricultural zoning districts within the Urban Limit Line to be consistent with the goals and policies in this General Plan. Minimum lot sizes for prime productive agricultural soils designated agricultural use in the Land Use Element(Class I and II)shall be set at 40 acres outside the Urban Limit Line. Infrastructure Services 8-ac. Consider detaching land in agricultural production not planned for development from any special taxing districts which are intended to serve urban needs,such as sewage treatment and hospital districts. 8-ad. In a manner consistent with growth management policies, allow water lines or other urban infrastructure which must be constructed across agricultural properties outside LAFCO designated Spheres of Influence in order to serve parks,other open space uses,or existing urban development,of a size as needed to serve the open space or existing urban uses. Do not require adjacent property owners to pay for the service, and generally mitigate to an insignificant level any identified growth-inducing impacts of the project. " 8-ae. Provide a circulation system appropriate to rural development to support land uses and economic activity. 8-af. Discourage the construction of growth-inducing highways or roads serving areas outside LAFCO designated Spheres of Influence unless the growth-inducing impacts of the project have been mitigated Highways built in non-urban areas should limit access to what is necessary to serve planned land uses and emergency needs. �... 8-ag. Encourage water reclamation and other public improvement projects which would increase,enhance,and protect agricultural land and its production capabilities. ,,, Agricultural/Urban Buffers and Conflicts 8-ah. Require adequate setbacks for any non-agricultural structures located within or adjacent to cultivated agriculture. 8-32 ""' 8.Conservation Element 8-ai. Where a discretionary development permit is sought within or adjacent to agricultural districts,reduce potential conflicts by creation of a natural or constructed buffer between the agricultural and urban land use. Such buffers must occur on the parcel for which the discretionary permit is sought. 8-aj. Where unmitigable conflicts exist between agricultural and residential uses, generally give priority to maintaining the agricultural use. 8-ak. In grazing areas, include within buffers fencing that will effectively contain grazing animals, keep domestic dogs out of grazing areas,and deter trespassing. 8-al. Conduct a study of the nature and extent of the conflicts between agriculture and urban land uses;identify the present and future areas where agriculture and urban land uses border one another;establish specific design guidelines which address: (1) the appropriate width and design features of buffer areas and fencing; (2) the necessary organizational components of homeowners' association language that provide for maintenance of buffers and fences and other measures such as surety bonds; (3) necessary amendments to the Zoning Ordinance and Subdivision Ordinance which assure that the design guidelines are rigorously imposed and enforced; and (4) control of trespassing,crop theft,and vandalism. 8-am. Require an agricultural notification statement in the proms deeds for all new residential lots created in or adjacent to planned agricultural districts. The statement shall inform owners about allowed adjacent agricultural practices. 8-an. Sponsor educational programs in cooperation with the county's school districts and the East Bay Regional Park District to inform students regarding need to respect agricultural uses. 8-ao Dro"Cl-e. Contijiue to iiMlement the"Right-to-Farm"Ordinance which protects ranchers and farmers within &a%.Yar agricultural district from nuisance complaints and unreasonable restrictions or regulations on farm structures or farming IKL",L practices. The ordinance will describe normal farm practices expected to occur in agricultural areas and assure the right of the fanner or rancher to continue such practices subject to appropriate health and safety standards. 8-ap. Vigorously enforce the provisions of the existing State of California agricultural nuisance law by the appropriate County departments. 8-aq. Control the predation on grazing animals by domestic dogs by: (1) establishing a county-wide law which prohibits free running dogs; (2) posting grazing areas with signs specifying the provisions and penalties imposed by the law; (3) imposing civil fines upon dog owners whose dogs damage livestock; and (4) increasing efforts by County Animal Control to manage free running dogs. 8-33 8.Conservation Element Programs to Support the Economic Viability of Agriculture 8-ar. Create and support a"Locally Grown in Contra Costa"marketing program. Permit and support a wide variety of promotional and marketing activities of county-grown and processed products. Continue to support the"Harvest Time"Program. 8-as. Research means of maintaining and improving the economic viability of agriculture in the County. 8-at.

There are two main sources of renewable energy available to the County: wind energy and solar power. 8-35 8.Conservation Element The Energy Resources Conservation and Development Commission of the State of California has identified the Altamont Pass area,including the Byron Hills portion of Contra Costa County,as an area with high wind potential. The private sector responded to that information and to federal and State tax incentives,which no longer exist,by moving rapidly into the wind energy business as a secondary use to agricultural pursuits. Applications for clusters of wind turbines are generally referred to as"Wind Farms." While the County has approved a substantial number of wind turbines and a large number of units have been constructed under those approvals, there is more property within the wind resource area that could be considered for additional wind farm development. This potential needs to be balanced against protection of the environmental resources of the southeast County area. The County's mild climate makes solar heating feasible if structures are properly sited in developments and have their solar access protected. State legislation now exists to protect solar access to individual properties. Solar heating for swimming pools has become common;however,use of this resource is still limited. Additionally,there are opportunities for conversion of municipal and other wastes to energy resources(e.g.,methane). Furthermore,retrofitting existing structures can save substantial amounts of energy. RENEWABLE ENERGY RESOURCES GOALS 8-K. To encourage the use of renewable resources where they are compatible with the maintenance of environmental quality. 8-L. To reduce energy use in the County to avoid risks of air pollution and energy shortages which could prevent orderly development. MAP OF RENEWABLE ENERGY RESOURCE AREAS Figure 8-3 shows the generalized boundaries of the wind energy resource areas based on materials developed for the State Energy Commission. The map identifies those areas that experience average wind speeds capable of being utilized for wind energy turbines(generally at least 15 mph at a height of 70 feet. RENEWABLE ENERGY RESOURCES POLICIES -- 8-49. Commercial wind farms shall be restricted to the south Byron Hills portion of the County. 8-50. New residential uses should be discouraged within the wind energy areas(depicted in Figure 8-3),since clusters of wind turbines generate noise. Turbines could become a nuisance if new subdivisions or residences are allowed immediately adjacent to the existing turbines or on properties already approved for wind turbines. fimwm 8-51. All new wind turbine applications shall comply,at a minimum,with the site-specific criteria included in the wind energy conversion systems regulations in the County Ordinance Code. ... 8-52. Energy recovery projects,e.g.methane recovery from sewage(biomass),shall be encouraged,subject to adequate environmental protection. 8-53.

Mineral extraction is important in Contra Costa County,as in other counties,because minerals such as crushed rock,sand,among others,supply the necessary components for local home building as well as for a diverse array of other industries. As such,the mineral industry is responsible for significant employment within the County. --� To protect valuable mineral resources in California,the State Legislature has adopted the Surface Mining and Reclamation Act(SMARA),which includes a process called"classification-designation." The purpose of this process is to provide local agencies with information about the location,need and importance of various mineral resources within their jurisdiction,and to ensure this information is used in local land use decisions. The fust mineral commodity which has been researched and designated by the State in each county is"construction aggregate,"which includes sand,gravel and crushed rock. The most important mineral resources that are currently mined in the County include crushed rock near Mt.Zion,on the north side of Mt.Diablo,in the Concord area;shale in the Port Costa area;and sand and sandstone deposits,mined from several locations,but focussed in the Byron area of southeast County. -- MAP OF MINERAL RESOURCES AREAS Figure 8-4 maps the significant mineral resource areas,found within the unincorporated area of the County,which this plan will protect. ' - Figure 8-4 is a regionally significant deposit of diabase located in the Mt Zion area near Concord and Clayton. —" i. Diabase is an intrusive igneous rock which is used extensivelyfor roadbase and as rip-rap to prevent erosion.Both Lone Star and Kaiser quarries utilise this tee. Their continued operatian is portant to the County and the region. Any expansion of the Mt.Zion quarrying operations will require a new County permit. The permit process shall include a complete analysis of impacts on Mt. Diablo State Park. Ultimately, upon closure of the mining operations,the quarried land should be considered for transfer to the State Park. Concord is considering residential development adjacent to the Mt.Zion quarries. Figure 8-4,ealHASi.sts-efidentifies,a geological deposit of domegine sandstone,located just south of Camino Diablo and east of Vasco Road. This mineral resource is a valuable commodity for the continued economic vitality of Contra Costa County, as it is the sole deposit of this material in the State of California,and an important resource nationally. Domegine sandstone is used by Pacific Gas&Electric Company as trench backfill and is a primary ingredient in the manufacture of heat-resistant glass used in the national space program. The resource extends beyond the boundaries -- designated by the State. This plan calls for the protection of the et#ffe sandstone resource area. An additional area in the County which has a long history of mineral resource production is located near Port Costa. Mining in this area began at the turn of the century to support a brick manufacturing operation which is unique in the County,and one of only a few in the entire State.Mining and brick production have been continuous from 1905 to the present,under several different ownerships. In 1966,a lightweight shale aggregate facility was constructed. This resource area is designated for protection on this plan. The Carquinez Straits Regional Shoreline Park,now being developed in the area,surrounds the site. Efforts will be required to ensure the compatibility of park and recreation uses with the mining operations. 8-38 LJ ' Q t � t � r t � v � d r yM•MMMt lbd � N�` f�+1, sup m 0 At i der �,.•o / i tj ! ! 1 tl! itr t p t t F 4 'ti U W %% U Cd 4 4 uj U. r d*"Rd v� ♦ift Vp tV Cds ,»J W �w C O ti,d tU ti✓ 00 a Page 8.39 b w 8.Conservation Element MINERAL RESOURCES GOALS 8-M. To ensure the continued viability of mineral extraction operations which are important to the County's economy. 8-N. To protect areas of identified valuable mineral resources from incompatible nearby land uses through zoning and other land use regulations. 8-0. To minimize and buffer the impact of surface mining activities on the surrounding land uses and the natural environment. MINERAL RESOURCES POLICIES —' 8-54. Mining and quarrying shall be a permitted use in certain privately owned areas which are in an open space designation in the General Plan (e.g. Open Space, Agricultural Lands, etc.) and which contain known -- mineral deposits with potential commercial value. These deposits include,but are not limited to,rocks, gravel,sand,salt and clay. -55. The shale mined at the Port Costa Materials Company site within an area designated as Heavy Industry and Agricultural Lands is compatible with this plan, although the long-term plan for the site, upon completion of quarrying,is for open space and park uses. 8-56. Incompatible land uses shall not be permitted within the mineral resource impact areas identified as containing significant sand and gravel deposits(as shown in Figure 8-4). 8-57. Incompatible uses are defined as land uses inherently incompatible with mining and/or uses that require a high public or private investment in structures, land improvements, and landscaping that prevent mining because of the higher economic value of the land and its improvements. 8-58. Future development in the vicinity of valuable mineral resource zones shall be planned and designed to minimize disturbance to residential areas or other sensitive land uses and to permit the safe passage of quant'trucks. 8-59. Development of compatible land uses shall be encouraged within 1,000 feet of the quarrying sites. Compatible uses include secondary sactivi related to the quarry operation,recreation facilities,parks,agricultural uses,and permanent open space. ..._. 8-60. Opportunities to recycle resources and materials related to quarrying operations shall be encouraged where they are compatible with adjacent land uses. 8-61. Reclamation plans prepared for the closure of quarries shall include conditions addressing the future use of the property,and a condition of the reclamation plan shall assure that future use. mom 8-62. Any proposals to expand existing quarries,or to create new quarries,adjacent to Mt.Diablo State Park shall carefully analyze impacts upon the park. MINERAL RESOURCES IMPLEMENTATION MEASURES 8-bt. Rezone designated mineral resource areas to stringent agricultural zoning designations(A-20,A-40,or A-80) MOMW to protect them for future recovery and from incompatible land uses. 8-bu. Establish a buffer zone around designated resource areas which will be rezoned to restrictive agricultural zones of A-20,A-40 or A-80. 8-bv. Encourage the recording of notices on property titles in mineral resource areas identifying the presence of important mineral resources. 8-40 .- 8.Conservation Element 8-bw. Limited residential or ranchette development of mineral resource properties maybe appropriate,but residential use shall be identified as secondary to mineral operations and will not be allowed to preclude the full utilization of identified mineral resources. Any nearby residential use will be permitted conditionally after recognizing the probable expansion of mineral operations and accepting the posse'ble nuisance and inconvenience associated with mineral operations. 8-bx. Require the posting of bonds for all new mining and quarrying permits to guarantee timely and faithful performance of reclamation and mining plans. 8-by. In analyzing the environmental effects of mining operations,the County shall consider,at a minimum,the following concepts in granting a new permit: (1) natural vegetation for buffering; (2) adequate setbacks; (3) central location of processing equipment and equipment storage; (4) dust control; (5) adequate access roads; (6) erosion control; (7) revegetation and re-establishment of natural appearing features on the site; (8) ultimate land use; (9) hours of operation; (10) night lighting; (11) security fencing; (12) noise impacts; and (13) protection of water quality. 8-bz. work with the Cities of Concord and Clayton to protect the aggregate resources around Mount Zion. 8.10 SOIL RESOURCES INTRODUCTION Contra Costa County is within the central Coast Range Geomorphic Province of California. This province consists of a northwest-trending series of mountain ranges and intermontane valleys. Unconsolidated alluvium,terrace deposits and bay mud occupy the lowland areas. These earth materials consist of sand,silt,clay and gravel of variable density and strength. Alluvial and terrace deposits occupy the intermontane valleys and lower foothills and Bay muds occupy the eastern northern and northwestern margins of the County. Figure 8-5 shows the Count.'s general soils characteristics. Soils of the region can be classified in three broad categories: 1)Lowland Soil Associations,2)Tidal Flat-Delta- Marsh Lowland,and 3)Upland Soil Associations. Each is briefly described below. 1) Lowland Soil Associations. The Soil Conservation Service recognized six central lowland soil associations. Most of these soil associations are slowly to very slowly permeable,highly expansive and corrosive with slight erosion hazards. 2) TidalFlat Delta-�Lowlands. The SCS descnIes three soil associations in the lowlands ofthe Tidal Flat-Delta-Marsh area. Soils of these associations are highly expansive,very highly corrosive,and moderately to slowly permeable. 3) Upland Soil Associations. Five upland soil associations were recognized by the SCS. These associations are generally highly expansive and corrosive with moderate to slow permeability. Different soil types have varying levels of susceptibility to erosion,but all soils benefit from conservation management practices. when erosion occurs,topsoil is lost resulting in reduced crop productivity and sedimentation problems downstream. In turn, sedimentation can fill waterways, diminish water quality, and damage sensitive habitats. Erosion occurs when high rainfall,lack of cover,fragile soils,and steep slopes combine. Urbanization,development activities,recreation,agricultural and logging practices increase erosion. 841 K� .'11 �'�rr�w�� - ��■■r►—+ wry � — 1 !P -A7 0 C3 cc ■/'ter L., l a jr I 1 m f if IF mml ML iii i_ �W' #-'r- 1 i L. ` L^ r t >>w�- • tisk%o��� Y r 1 rTV1 �_ to vmww a!rmn ow r i.: }= 1 ......• yrs_ - NOW- -T AL dgfAMbW- ��AWt ��.A n l IL Ll !' �• .- �..+-ir l 1.

Wind erosion is the greatest factor in soil loss in the Delta area. Grain crops in the TassaJara region of the County are subject to water erosion. Soils in hillside grazing areas are generally stable,but have been stressed recently by several years of drought. Grassland vegetation,which stabilizes hillsides,lacks the root structure to hold soils effectively in a severe rainstorm(over two inches precipitation). However,as annual rainfall returns to pre-drought averages,the root structures will repair and the hills will stabilize.'4* Conversion of agricultural lands to housing or other development temporarily renders exposed soil vulnerable to erosion. This condition improves and stabilizes following construction, if proper construction drainage and landscaping practices have been followed. AGRICULTURAL SOILS Less than 40 percent ofthe land in Contra Costa County consists of Class 1,H,and III soils. Class I and II soils are considered "prime,"or the very best soils for fanning.2CIass H soils are found on the Diablo-San Ramon Valley floor,a large part of the Pittsburg-Antioch Plain,throughout the San Joaquin Delta region,and along,the stream channels of many smaller valleys in the Briones Hills and Diablo Range. Because these areas are located along the traditional transportation corridors,urban development has also moved much of this Class 11 land fnxn production,most recently in the Pittsburg-Antioch area. The largest remaining agricultural area with Class I and 11 soils includes approximately 17,000 acres centered around Brentwood in East County. The area of prime soils extends westward into the Deer Creek,Marsh,and Kellogg valleys,southward to the town of Byron,extends eastward to Discovery Bay,and northward along the ATSF railroad tracks into Oakley. Figure 8-5 illustrates the prime soils types in the East County where most of the impacts of the proposed County General Plan will occur. Class I and II lands in the Soil Conservation Land Use Capability Classification is a factor which was used in establishing the ULL. Important soil types in the Brentwood area include Brentwood clay loam(designated"Bb"on the figure)which is Class I soil; Brentwood clay loam,wet("Bc,"Class 11);Capay clay,0 to 2 percent slopes('CaA,"Class H);Capay clay,wet,0 to 2 percent slopes("CbA,"Class H);and Rincon clay loam,0 to 2 percent slopes("RbA,11 Class II). Must of the Class I and H soils in East County are still under agricultural production although significant development pressure exists in the area. Large areas of Class III soils are found on the islands of the San Joaquin Delta and on lands in the growing Oakley community. Most ofOakley is composed ofC1,ass II Delhi sand,describedby the US.Soil Cbmammfion Service as"excessively&ufiied soils" where runoff is slow or very slow. Delhi sand is used to grow irrigated almonds,vineyards,and some walnuts.The--re Class M soils found on Delta islands are form the Kingile and Rindge associations,which are described as"very poorly drained organic soils"used primarily for inigated field com,milo,asparagus,tomatoes and pasture-I I The next category of soils,Class IV soils,tend to be poorly drained,have excess salts,or are too steep for continuous cultivation. Where cultivable,as in East County and in the southern Diablo Range region,they are suited to irrigated pasture and dry fanning of grains such as barley. Where too steep for cultivation,as in the foothills of the Diablo Range, Class IV soils are excellent grazing land less subject to erosion and overgmzing than other range areas. The role of climate in mitigating some of the shortcomings of the soil characteristics in California makes the distinction between prime and non-prime less clear. In Contra Costa County,where the influence of coastal fog is felt in the western and central regions,the growing season in areas such as Tassajara Valley and Morgan Territory is extended and even Class IV lands may support dry field crops. Maps and Inventory of Soil Resource Areas Figure 8-5 illustrates the location of soil resources found in the County. The soil resource preservation policies found in this section focus on the soil resources and important agricultural soils of the County. SOIL RESOURCES GOALS 8-P. To encourage the conservation of soil resources to protect their long-term productivity and economic value. 8-43 8.Conservation Element 8-Q. To promote and encourage soil management practices that maintain the productivity of soil resources. The following policies and implementation measures, in addition to those identified in the Agricultural Resources Section,shall be used to carry out these goals. SOILS RESOURCES POLICIES 8-63. The County shall protect soil resources within its boundaries. 8-63. Erosion control procedures shall be established and enforced for all private and public construction and grading projects. 8-64. The County shall support and encourage existing local,State,and Federal soil conservation and restoration programs within its borders. 8-65. In the absence of more detailed site-specific studies,determinations of soil suitability for particular land uses shall be made according to the Soil Conservation Service's"Soil Survey of Contra Costa County"., 8-66. The existing County slope map shall be used to identify areas in the County where slope poses severe constraints for particular land uses. 8-67. Lands having a prevailing slope above 26 percent shall require adequate special erosion control and construction techniques. 8-68. Lands having a high erosion potential as identified in the Soil Survey shall require adequate erosion control methods for agricultural and other uses. SOILS RESOURCES IMPLEMENTATION MEASURES 8-ca. Apply the appropriate land use designations to areas with productive agricultural soils. 8-cb. Annually review the California Department of Conservation's updated Important Farmland's Map and the amount of land in the County converted to and from agricultural use. 8-cc. Design discretionary projects so that structures and roads are not g a -zener lly located on slopes of 26 percent or greater. This requirement is not intended to preclude existing parcels as building lots if Health Department and Building Department requirements can be met. Development Review Process 8-cd. Include erosion control measures for any discretionary project involving construction or grading near waterways or on lands with slopes exceeding 10 percent. 8-ce. Encourage agricultural land owners to work closely with the U.S.Soil Conservation Service and local Resource Conservation Districts to reduce soil erosion and to encourage soil restoration. 8-cf. Require a soil conservation program to reduce soil erosion impacts for discretionary projects which could increase waterway or hillside erosion. Design improvements such as roads and driveways to retain natural vegetation and topography to the extent feasible. 8-cg. Retain natural vegetation and topography to the extent economically feasible for any discretionary project improvements near waterways or in areas with a high risk of erosion as noted in the Contra Costa County Soil Survey. 8-44 8.Conservation Element 8-ch. For discretionary projects, prepare and submit to the County Board of Supervisors an erosion and sediment control plan to be included as part of the project where appropriate. 8-ci. Continue to enforce the Uniform Building Code to reduce erosion and slope instability problems. 8.11 OIL AND GAS RESOURCES INTRODUCTION Contra Costa County is one of the leading counties in the State in terms of natural gas production. The County also has a small volume of oil production. The most productive oil and gas fields are concentrated in the eastern portion of the County. The area contains the Brentwood,Oakley,East Brentwood and Dutch Slough fields and a portion of the Rio Vista field,the largest of its type in the State. These fields are all located north of the City of Brentwood and east of Antioch. The only other field of significance,Los Medanos,is located in the hilly area north of Route 4,between Bay Point and the Concord Weapons Station. Other smaller resource areas are scattered throughout the County. The production of oil and gas from wells is an important secondary use of land in the County. The policy issues on this matter deal more with regulation on the extraction of this resource than the appropriateness of use. Issues which need to be dealt with include noise(including drilling,operation,and production enhancement),aesthetics, access to the wells and the impact of equipment on public roads. Efforts need to be made to encourage unified drilling sites to minimize these land use impacts. Natural gas storage areas,such as the Los Medanos Gas Storage field,should be encouraged as more efficient than using surface storage tanks. OIL AND GAS RESOURCES GOALS 8-R. To achieve utilization of oil and gas resources in a manner beneficial to all County residents. 8-S. To ' ' ' e the impact of oil and gas extraction activities on the surrounding land uses and the natural environment. �- OIL AND GAS RESOURCES POLICIES 8-69. The production of gas and oil resources shall be encouraged as a way to support the agricultural viability of nual areas. 8-70. New wells shall be reviewed and approved in a fashion to minimize noise,aesthetic and public safety problems. 8-71. The potential impacts ofoil and gas extraction on the subsistence ofland,especially]andnearbodies ofwater and in the Delta,should be investigated. Ifnecessary,special regulations should be proposed and applied to existing operations. 8-72. New wells shall not be allowed to be drilled in wetland areas. 8-73. Where safety can be assured, the storage of gas in underground natural basins shall be considered preferable to above ground storage tanks. OIL AND GAS RESOURCES IMPLEMENTATION MEASURES 8-cj.

Contra Costa County has a moderate climate,similar to a Mediterranean climate. Measurable rainfall recorded annually in the City of Richmond averages about 21.8 inches per year,with the majority falling between October and April. Average temperatures are mild,and generally range between 50 and 66 degrees F in Richmond. The County is bounded by San Francisco Bay and San Pablo Bays to the west,by Suisun Bay and the channels of the (Sacramento and San Joaquin Rivers), and the south by Alameda County. The San Francisco Bay Delta System (including San Pablo Bay)is generally regarded as the most important water body in California. It is used extensively for both recreational and commercial purposes,and supports a diverse flora and fauna. Water from about 40 percent of the land in California drains into the Bay and comprises most of the State's agricultural and urban supplies. The San Francisco Bay has been greatly altered from its natural conditions by human activities. The quality of waters of the San Francisco and San Pablo Bays vary seasonally. For most of the year,water quality is similar to that of the Pacific Ocean. From December through April,water quality is affected by freshwater inflow form the Sacramento-San Joaquin Delta and from other local,smaller tributaries that drain urbanized portions of Contra Costa County and the entire Bay Area. Water quality in the Delta is affected by a multitude of factors including upstream reservoir releases;tidal changes;the -- discharge of agricultural diverters;and the export rates of the State Water Project and the Central Valley Project. A number of statutes have been enacted specifically regarding the Delta. The California State Water Resources Control has been conducting hearings regarding the Bay/Delta system and the future of water diversion from this system. ..... The California State Regional Water Quality Control Board (RWQCB), San Francisco Bay Region, is the government agency responsible for protecting the health of San Francisco Bay. A water quality control or"basin plan"has been prepared that serves as a blueprint for water pollution control activities in the Bay. The basin plan ' identifies a number of beneficial uses of the Bay that must be protected,including non-contact recreation;wildlife habitat;preservation of rare and endangered species;estuarine habitat;warm freshwater and cold freshwater fish habitat;fish spawning and migration;industrial service supply;navigation;and commercial and sport fishing. ^" All of Contra Costa County's water drains either directly or indirectly into the Bay/Delta system. Water from the western,urbanized portion of the County drains directly into San Francisco Bay or San Pablo Bay,while that from the northern and eastern portions drain into Suisun Bay and the Delta river channels,eventually flowing into San Pablo and San Francisco Bays. The south-central portion of the County is within the Alameda Creek drainage basin;this area's water drains south to Alameda Creek,then west to the San Francisco Bay.

The water quality of creeks within urbanized areas has been degraded by the presence of high levels of suspended solids,together with traces of contaminants associated with the operation ofmotorvehicles such as oil and grease,gasoline and other hydrocarbons,lead,rubber,etc. No serious water quality problems exist within the County,however,an unknown quantityofhazardous wastes are currently dim ofby or unsafe means.These disposal practices could lead to surface and groundwater contamination that may not be detected Certain portions of the County are more prone to flooding than other portions. In general,the low-lying areas adjacent to San Francisco,San Pablo and Suisun Bays,and the eastern portion of the County near the San Joaquin River are the most susceptible to flooding. Urban and Rural Creeks When Contra Costa County was sparsely populated and predominantly rural, creeks and streams flowed uninterrupted from the coastal hills to the Bay and Delta. These watercourses supported a wide variety of plant, animal, and aquatic life. Riparian vegetation and strearnside habitats minimized erosion, sustained perennial streams, contributed to groundwater reserves, moderated temperature extremes and provided an attractive and pleasant environment. It is of benefit to County residents to preserve vestiges of this pre-settlement environment and to work toward re-establishing this environmental heritage. As agricultural land in portions of the County was converted to urban uses,permeable ground surfaces were replaced with impervious surfaces. Paving,roofs,and efficient drainage systems reduced the proportion of rainfall percolating into the ground and increased the volume and velocity of surface runoff carried to the creek channels. This resulted in increased flood frequency and severity,channel cutting and loss of vegetation in upper watersheds,and silting in lower channels. Creeks and streams were relocated and realigned to accommodate increased flows. Channels were increased in width and depth and lined with concrete or rip-rap. Creeks were placed in conduits and culverts. Although these improvements have been effective in transporting stormwater runoff and in reducing flooding and property damage, these benefits have come at the expense of natural channels and native riparian habitat, which are difficult to replace and are sometimes irreplaceable. Traditionally,the more efficient the drainage system feeding into a natural watercourse,the greater the damage to natural waterways and streamside vegetation and the greater the downstream flood damage risk.The continued use of traditional facilities in individual development projects exacerbates these problems. Many undeveloped properties he upstrearri from established urban development. Each new development project which increases peals runoff',although seemingly insignificant, contributes to a future need to make improvements to existing downstream public flood control facilities and natural channels at substantial cost to county residents. The use of alternate stormwater management techniques such as the floodplain,the levied floodway,the bypass channel,and the detention basin can either lessen or eliminate completely the reed for these nnproverrrents, reducing public costs and providing a more diverse and attractive environment. While it may be desirable to keep all of the renmining creeks and streams in their natural state,this is not always possible. Within existing developed areas,structural modifications to watercourses are often the only viable alternative. The shortage of available land within a built-up urbanized area,as well as its high cost,may rule out the possibility of keeping a watercourse in its natural state. Where this is the case,alternate structural approaches can be utilized which are designed to be compatible with their environment. Instead of rip-rap and concrete,slope protection devices can be used to stabilize banks. Landscaping can also be used to soften the visual impact of structurally modified watercourses. 847 8.Conservation Element Control of flooding is not the only drainage concern. With increased development and stormwater runoff,a wide variety of nutrients and toxic substances have been introduced into county waters. Nutrient wastes in the form of sewage,agricultural fertilizers,and manure lead to reduced dissolved oxygen in surface waters and limit the capacity of water to support aquatic organisms. Toxic substances, such as industrial wastes, insecticides and herbicides, can poison wildlife and become concentrated in the food chain. Both types of pollutants can adversely affect the quality of groundwater. Erosion and sedimentation often inflict heavy public costs for flood control,harbor and channel dredging,post- flood clearing and private property damage,besides damaging aquatic life and carrying toxic substances into public and private water supplies.Design and construction techniques have been developed which are cost-effective and essential to erosion and sedimentation reduction. There is also a need to provide enhanced opportunities for public access to creeks,streams,and drainage channels,where conditions and liability constraints permit. Total county population will continue to increase and with it the demand for recreation facilities will grow. Drainage features which can be made into parks or open space,or incorporated as assets into new development projects,will be used and appreciated by present and future county residents. The Contra Costa County Flood Control and Water Conservation District is empowered to control flood and storm OWN" waters throughout the county. Even though the district has no direct influence over the County or the cities regarding land use and planning matters,the district does develop drainage plans for entire watersheds which cross jurisdictional boundaries. These drainage plans specify the flood control improvements needed to serve planned development in the area and are used to set drainage fees assessed against new development. A more-complete discussion of adopted and proposeddrainage per,as well as numerous flood control goals,policies and implementation measures,are included in the'Drainage and Flood Control"section of the Public Facilitie&Scrvices,Element (Chapter 7). Raiders should note that d=is a great deal of overlap between these two sections of the General Plan;some goals and policies are repeated in both sections. Both this section and the"Drainage and Flood Control"section in ClmpteO sbouldbe consulted together for a full understanding of County policies regarding flood control,waterways and areas. WATER RESOURCES GOALS 8-T. To conserve,enhance and manage water resources,protect their quality,and assure an adequate long-term supply of water for domestic,fishing,industrial and agricultural use. 8-U. To maintain the ecology and hydrology of creeks and streams and provide an amenity to the public,while at the same time preventing flooding,erosion and danger to life and property. 8-V. To preserve and restore remaining natural waterways in the county which have been identified as important and irreplaceable natural resources. 8-W. To employ alternative drainage system improvements which rely on increased retention capacity to lessen or eliminate the need for structural modifications to watercourses,whenever economically possible. 8-X. To enhance opportunities for public accessibility and recreational use of creeks, streams, drainage channels and other drainage system improvements. GENERAL WATER RESOURCES POLICIES NNW 8-74. Preserve watersheds and groundwater recharge areas by avoiding the placement of potential pollution sources in areas with high percolation rates. 8-75. Preserve and enhance the quality of surface and groundwater resources. 8-76. Ensure that land uses in rural areas be consistent with the availability of groundwater resources. 8-77. Provide development standards in recharge areas to maintain and protect the quality of groundwater supplies. 8-48 soon moo 8.Conservation Element Policies to Protect and Maintain Riparian Zones 8-78. Where feasible, existing natural waterways shall be protected and preserved in their natural state, and channels which already are modified shall be restored. A natural waterway is defined as a waterway which can support its own environment of vegetation,fowl,fish and reptiles,and which appears natural. 8-79. Creeks and streams determined to be important and irreplaceable natural resources shall be retained in their natural state whenever possible to maintain water quality,wildlife diversity,aesthetic values,and recreation opportunities. 8-80. Wherever possible,remaining natural watercourses and their riparian zones shall be restored to improve their function as habitats. 8-81. Fisheries in the streams within the County shall be preserved and re-established wherever possible. 8-82. Riparian habitat shall be protected by providing for channel cross-sections adequate to carry 100-year flows,as per policies contained in the Public Facilities/Services Element. If it is not possible to provide a channel cross section sufficient to carry the 100-year flow,then detention basins should be developed. 8-83. The remaining willow riparian areas in East County shall be protected from intensive cattle grazing. 8-84. Riparian resources in the Delta and along the shoreline shall be protected and enhanced. Policies for New Development Along Natural Watercourses 8-85. Natural watercourses shall be integrated into new development in such a way that they are accessible and provide a positive visual element. 8-86. Existing native riparian habitat shall be preserved and enhanced by new development unless public safety concerns require removal of habitat for flood control or other public purposes. 8-87. On-site water control shall be required of major new developments so that no increase in peak flows occurs relative to the site's pre-development condition,unless the Planning Agency determines that off-site measures can be employed which are equally effective in preventing adverse downstream impacts. 8-88. New development which modifies or destroys riparian habitat because of needed flood control,shall be responsible for restoring and enhancing an equivalent amount of habitat within or near the project area. 8-89. Setback areas shall be provided along natural creeks and streams in areas planned for urbanization. The setback areas shall be of a width adequate to allow maintenance and to prevent damage to adjacent structures,the natural channel and associated riparian vegetation. The setback area shall be a minimum of 100 feet;50 feet on each side of the centerline of the creek. 8-90. Deeded development rights for lands within established setback areas along creeks or streams shall be sought to assure creek preservation and to protect adjacent structures and the loss of private property. 8-91. Grading,filling and construction activity near watercourses shall be conducted in such a manner as to minimize impacts from increased runoff,erosion,sedimentation,biochemical degradation,or thermal pollution. 8-92. Revegetation of a watercourse shall employ native vegetation, providing the type of vegetation is compatible with the watercourse's maintenance program and does not adversely alter channel capacity. 8-93. Particular care shall be exercised by development proposals to preserve and enhance riparian corridors along creeks which connect to the fireshwater marsh segments of coastal areas in the North Central and East County areas. 8-94. Applications to expand marine uses shall be carefigly evaluated to ensure that a gain,not a loss,ofany associated riparian vegetation will result Runoff of pollutants into marsh and wetland areas from nay urban development,should be prevented by prohibiting any stone sewer outflow pipe in such areas and by requg berm or gutter structures at the outer boundary of the buffer zmes which would divert runoff to sewer s)Aerns for,ransport out of the area. 849 8.Conservation Element WATER RESOURCES IMPLEMENTATION MEASURES Riparian Resources Inventory 8-co. Work with appropriate agencies to inventory the County's riparian resources and to identify areas warranting preservation and enhancement. Zoning and Code Revisions 8-cp. Review and revise the County ordinance code to provide for the protection and enhancement of watercourses and riparian vegetation,as outlined in the above policies(e.g.building setback requirements, regulations limiting the removal of trees and vegetation,etc.). Other Programs 8-cq. Develop a program that fosters the participation of public agencies,private organizations and individuals in the development of watershed management practices that reduce soil loss and excessive runoff(i.e. control of grazing in upper watersheds,timing of release of water from upstream dams,revegetation of upper watersheds),and that minimize the effect on downstream areas. 8-cr. Develop a program for the restoration of riparian vegetation in rural creeks where grazing activities are reducing the extent of the vegetation and are eroding channel banks. 8-cs. Develop guidelines for creek maintenance practices which assure that native vegetation is not removed ,,, unnecessarily. These guidelines should also assure that maintenance is scheduled to minimize disruption of wildlife breeding practices. 8-ct. Re-evaluate the flood control drop structures and long spillways that have been constructed in many of the creeks in North Central County(Walnut Creek,Concord, and Pleasant Hill)to determine the feasibility of constructing fish bypass facilities which would allow anadromous species access to inland spawning sites. Development Review Process 8-cu. Review all public and private projects adjacent to and within creeks and streams to determine their conformance with the policies of this General Plan. 8-cv. As a priority, define and implement a development review process for new projects that ensures conformance with the stream and riparian corridor protection policies of this plan. 8-cw. During the review of proposed development plans,the County staff shall require a building setback of at least 100 feet along natural creeks and streams,and seek to obtain deeded development rights on lands within setback areas. 8-cx. New parcels which are created shall inchide adequate space outside of the watercourses'setback auras for pools,patios,and t s to em=that property owners will not place i-----menu within the areas which require protection. 8-cy. Through the environmental review process,the likely effects of construction and other proposed activities on nearby natural watercourses and related open space shall be determined. Measures shall be identified that will mitigate these effects and encourage the preservation of natural waterways and related open space. Such measures may include,but are not limited to: (1) Clustering of buildings and other site design features; (2) Restoration or enhancement of other riparian habitat within or near the project area;and (3) Purchase of development rights for lands within other stream setback areas. 8-cz. When alteration of streambanks or streambeds is proposed,notify the State Department of Fish and Game in accordance with their authority under State law and/or when their assistance is needed. 8-50 --m 8.Conservation Element 8-da. As a condition of approval for discretionary permits which intensify cattle grazing, 100-foot buffer zones along creek systems should be declared"riparian preserves";establish cooperative agreements with land owners to fence off the areas from livestock;and,institute appropriate planting programs,as needed to replace vegetation. If necessary,install simple gravity flow pipeline systems to transport water from pool areas in the creek to water trough sites for cattle outside the riparian zone. 8-db. Require proposed recreation or housing projects which utilize the shoreline and water resources of the Delta to create slough systems with significant riparian plant communities equal in size to the project area itself. Prohibit construction of barren waterways. 8-dc. Require large industrial projects and expansions in the coastal regions of Antioch and Pittsburg to preserve and, if necessary, create a riparian buffer zone of at least 100 feet between the high tide line and the development edge. Apply conditions of project approval that minimize any surface runoff or storm sewer outflows from contaminating the riparian buffer zones. 8-dd. Require groundwater monitoring programs for all large-scale commercial and industrial facilities using wells. 8-de. Require proof of adequate groundwater in areas not served by municipal water purveyors. Require test wells or the establishment of community water systems in these areas. Deny discretionary applications unless a geologic report establishes that groundwater supplies are adequate and will not be adversely impacted by the cumulative amount of additional development. 8-df. Review and comment on projects and environmental documents that propose wastewater disposal methods which discharge into natural waterways. Request reclamation conservation and re-use programs to minimize discharges and protect water quality and aquifer recharge areas. 8-dg. Review of subdivisions using septic systems shall be conducted by the County's Environmental Health Department to ensure that leachates do not contaminate groundwater recharge areas. Consider on-site wastewater management districts in important recharge areas. 8-dh. Actively pursue the abatement of failing septic systems near waterways. 8-di. Encourage the construction of wastewater disposal systems designed to reclaim and re-use treated wastewater on agricultural crops,and for other irrigation and wildlife enhancement projects. 8.13 HARBORS INTRODUCTION The Port of Richmond is located at the western edge of Contra Costa County,approximately nine miles east of the Golden Gate Bridge. The Port consists of an Outer Harbor about five miles in length,and an Inner Harbor,which covers a distance of about 3.75 miles in length. The Outer Harbor faces natural,deepwater in San Francisco Bay; the Inner Harbor has been dredged from deep water in San Francisco Bay through shallow flats and marshlands. Port of Richmond facilities consist of piers,wharves and docks. Commodities handled at the Port include bulk liquids, bulk dry and scrap metal cargoes,gypsum rock,vehicles,and brake bulk. Container handling was initiated at a new Port of Richmond facility during the early 1980s.s5 ._ _ ,(100 ffnntl 9:10 beivada .. ent hO14 tons. pote"6Q] ww"AHHHH4 J PL OF At*L 01 f.-JR6ehmond Teminal The B. a7 r b Several small craft and recreational harbors or marinas are located along San Francisco Bay,Carquinez Strait,Suisun Bay, and the Sacramento River within Contra Costa County.

The w. State Air Resources Board has Statewide responsibility for air quality,and the Bay Area Air Quality Management District j has permitting authority for stationary air pollutant sources in the region. These agencies'participation in local land use planning is normally limited to commenting on Environmental Impact Reports. --71 rNem. szinalar Roam Xlillllleftrs • ti ' , 1 ' r and N icallar- • hewe � • Past efforts atimproving air quality have focused on'%v dware"type solutions such as requiring pollution abatement equipment for industrial sources or requiring catalytic converters on new automobiles. The simplest and most cwt-effective hardware-type air pollution control measures were dose first implemented;future measures of this type will provide ' ' 'ng re IM* Local air quality planning offers another means of addressing the air pollution problem. Future air quality will be partially determined by local land use and transportation decisions. Judicious land use and transportation planning at the city and county level represents another means of improving air quality on both the local and regional scale. Such planning can keep a balance between growth rates and improvements to the transportation system,reduce long distance commuting, encourage and support non-auto transportation,and reduce future land use conflicts related to air pollution. In a planning sense,air quality is closely related to several other areas within the General Plan. Listed below are other Elements of the Plan which contain policies and implementation measures that are consistent with efforts to improve air quality and are considered part of the Air Quality component of the General Plan. o Transportation and Circulation Element: circulation phasing and coordination roadway routing and design improvements alternative transportation and circulation systems o Land Use Element: jobs/housing balance,community boundaries(Urban Limit Line) growth management standards for timing of growth with the Urban Limit Line 8-52 8.Conservation Element o Safety Element: protection from hazardous materials AIR RESOURCES MAPS ANWANALYSIS Contra Costa County contains a multitude of air pollutant sources. Inventories of these sources have been prepared by the Bay Area Air Quality Management District, classifying sources as to type and strength.

The concentrations of pollutants in the atmosphere are dependant not only on the amount of pollutant emitted,but on the ability of the atmosphere to transport and dilute the pollutant. Some pollutants,such as ozone,are not directly emitted to the atmosphere by any sources,but are the result of chemical reactions in the atmosphere between other pollutants. The chemical reaction that creates ozone in an wban atmosphere occurs between reactive organic gases(ROG)and oxides of nitrogen (NOJ in the presence of sunshine. The rate of reaction is very dependent on sunlight and temperature, so ozone concentrations will depend on the strength of sunlight and the temperature as well as transport and dilution by the wind b a.

The western portions of the County show a very strong influence of winds through the Golden Gate. The prevailing wind directions at Berkeley and San Pablo reflect the direction to the Golden Gate: west at Berkeley and southwest at San Pablo. Ventilation in this area is very good, winds are persistent and strong and calms are relatively infrequent. Although heavily urbanized,this portion of the County has very good air quality due to the good ventilation characteristics,cool temperatures and lack of upwind sources of pollutants. The wind data for the inland Diablo-San Ramon Valley shows a strong influence of terrain on wind.Winds are channeled by terrain,and the area is very sheltered,with relatively low average wind speeds and a very high frequency of calm conditions. The potential for air pollution in this are is high because of reduced ventilation and wane temperatures which promote the formation of ozone.

T'r' AwA%- A� 9* OPEN SPACE ELEMENT 9.1 INTRODUCTION Contra Costa County is bestowed with a wide variety of natural and cultural resources which are currently held publicly or privately as open space. Natural open space areas include woods,mountains,lakes,streams, wetlands,and agricultural land. Scenic resources,parks and recreation land are also considered open space lands. Furthermore,the County has important historic and archaeological sites which qualify as resources and which should be preserved. The Open Space Element of the General Plan has three major components: (1) a policy framework for the preservation of open space lands, (2) an open space map identifying County lands subject to the policies contained herein,and(3)an implementation program. Natural resources, including Agricultural Resources, are discussed under the Conservation Element of the County's General Plan (Chapter 8). The Open Space Element analyzes open space classified as Scenic Resources,Outdoor Recreation,and Historic/Cultural Resources. As in the case with the preservation of natural resources and agricultural resources,the Open Space Element is significantly affected by policies reflected in Measure C -1990. These policies, found throughout this General Plan, include the 65/35 Preservation Standard, the Urban Limit Line, hillside protection polices, preservation agreements and the policy to advise LAFCO to respect and support the County's 65/35 Preservation Standard,ULL,and growth management standard when considering requests for incorporation or annexation to cities or service districts. The ULL works together with the 65/35 Preservation Standard to protect open space. Criteria for considering the location of the ULL includes open space,parks and other recreation areas,lands with slopes with a grade of 26 percent or greater, wetlands and certain other areas not appropriate for urban growth. Even if land is developed within the ULL,a substantial portion is to be retained for open space,parks and recreational uses. LEGAL AUTHORITY This chapter of the Contra Costa County General Plan encompasses many diverse issues dealing with the preservation and management of open space areas in the County. The chapter covers the issues required by the State General Plan laws to be addressed. d The legal requirements for the Open Space Element are included in Section 65560 et. seq. Q;nxw�of the California Government Code. The Open Space Element is a plan for the comprehensive and long-range preservation and conservation of"open space land." "Open space land"is defined in the statutes as any area of land or water which is essentially unimproved and devoted to an open space use and which is designated on a local,regional or State open space plan as open space for the preservation of natural resources,the managed production of resources,outdoor recreation,or for public health and safety. In adopting the requirement that all jurisdictions must prepare an Open Space Element,the Legislature found that the preservation of open space land is necessary not only for the maintenance of the economy of the State,but also for the continued availability of land for the production of food and fiber,for the enjoyment of scenic beauty, for recreation, and for the use of natural resources. The legislature further found that 9-1 9.Open Space discouraging premature and unnecessary conversion of open space land to urban uses is in the public interest -- because it discourages non-contiguous development patterns which tend to increase the costs of community services to community residents. Finally,the legislature found that the anticipated increase in the population of the State demands that cities, counties, and the State make plans at the earliest possible date for the —. preservation of valuable open space land and take positive action to carry out such plans by the adoption and strict administration of laws,ordinances,rules and regulations. Government Code Section 65564 requires that every local open space plan contain an action program consisting of the specific programs which the legislative body intends to pursue in implementing its open space plan. That action program is described in the implementation measures contained in this chapter and in the conservation element and in the CEQA mitigation monitoring program adopted concurrently with this General Plan. 9.2 RELATIONSHIP TO OTHER GENERAL PLAN ELEMENTS The Open Space Element is related to other elements of the General Plan and has equal legal status with all other sections of the Plan. The Open Space Element is closely related to the Conservation Element of the General Plan and is coordinated with that element. Primary impacts of the Open Space Element are expected on land use policies, -- and in view of the interplay with the ULL and 65/35 Preservation Standard the element is coordinated with the Land Use Element. In addition, the Open Space Element is related to the Public Facilities/Services Element and in that open space areas are designated based partly on seismic and landslide risk. With reference to the Land Use Element Map, the following map designations and their respective map symbols are considered to be open space designations within the definition contained in the State statute: o Open Space(OS) o Parks and Recreation(PR) o Agricultural Lands(AL) --- o Agricultural Core(AC) o Delta Recreation(DR) o Watershed(WS) o Water(WA) Lands outside the Urban Limit Line may be designated for landfills with the LF designation. LF is not an open space designation pursuant to the state open space planning statute, Government Code Sections 65560-65570, although LF lands may be surrounded by open space lands. Landfills are public purpose facilities, which are defined as non-urban uses in the Board of Supervisors'65/35 Land Preservation Plan, adopted by the County's voters as Measure C in November 1990. Facilities for public purposes are allowed outside the Urban Limit Line. The LF designation is consistent with, and implements,this provision of the 65/35 plan. ju rafPrQ;A6J11=4 aav%4AIA f. 9.3 RELATIONSHIP TO OTHER GENERAL PLAN DOCUMENTS r.. The goals,policies and implementation measures contained in this element are intended to guide planning for public and private projects that are subject either to approval of the County planning agency,or to review by County staff, although they may be under the jurisdiction of other public agencies operating in the County. Such goals, policies and implementation measures are intended to accord with the other elements of the General Plan,and have equal legal status with all other sections of the Plan. 9.4 OPEN SPACE ELEMENT ORGANIZATION mow 9-2 9.Open Space This chapter of the General Plan is divided into three sections that present background information,policies, maps,and implementation measures regarding: o scenic resources, including scenic ridges, hillsides and rock outcroppings; and, the San Francisco Bay/Delta estuary system; o historic and cultural resources; and o parks and recreation, including local parks,trails and paths, and private recreational facilities. 9.5 OVERALL GOALS AND POLICIES The following goals and policies are overall statements regarding the need to preserve and efficiently manage open space within the County. More detailed policies particular to each type of resource are discussed under separate topic sections in the Conservation Element of the General Plan. OVERALL OPEN SPACE GOALS 9-A. To preserve and protect the ecological,scenic and cultwaVhistoric,and recreational resource lands of the County. 9-B. To conserve the open space and natural resources of the County through control of the direction, extent and timing of urban growth. 9-C. To achieve a balance of open space and urban areas to meet the social,environmental and economic needs of the County now and for the future. OVERALL OPEN SPACE POLICIES 9-1. Permanent open space shall be provided within the County for a variety of open space uses. 9-2. Historic and scenic features,watersheds,natural waterways,and areas important for the maintenance of natural vegetation and wildlife populations shall be preserved and enhanced. 9-3. Areas designated for open space shall not be considered as a reserve for urban land uses. In accordance with Measure C-1990,at least 65 percent of all land in the County shall be preserved for agriculture,open space,wetlands,parks and non-urban uses. 9-4. Where feasible and desirable,major open space components shall be combined and linked to form a visual and physical system in the County. 9-5. The visual identities of urban communities shall be preserved through the maintenance of existing open space areas between cities and/or communities. 9-6. Open space acquisition shall be planned and funded, in concert with the region's staged transportation, landfill,and water and sewage plant and programs. 9-7. Open space shall be utilized for public safety, resource conservation and appropriate recreation activities for all segments of the community. 9-8. Development project environmental review will consider the effect of the project on the County's open space resources,whenever the project proposes to convert substantial amounts of land from an open space designation to an urban development designation. 9-3 AMMON 9.Open Space 9-9. The County shall preserve open space lands located outside the Urban Limit Line by declining to -- authorize requests for general plan amendment studies which would result in redesignation of such lands to urban land use designations. The County shall not designate any open space land located outside the ULL for an urban use. A substantial portion of land developed within the ULL shall be _•,. retained for open space,parks and recreational uses. 9.6 SCENIC RESOURCES INTRODUCTION Contra Costa County is perceived by many as a desirable place to live and work. A major component in that perception is the scenic vistas which are available throughout the County. While there are many localized scenic features in the County,there are two main resources which are treated in this section: (1)scenic ridges, hillsides and rock outcroppings; and(2)the San Francisco Bay/Delta estuary system. Throughout much of Contra Costa County,there are significant topographic variations in the landscape. The largest and most prominent of these hills form the backdrop for much of the developed portions of the area. --- Views of these major ridgelines help to reinforce the rural feeling of the County's rapidly growing communities. These major ridges provide an important balance to current and planned development. Individual home sites or housing tracts are sometimes constructed on ridge tops in such a way that the scenic views from the site are superb, but the view of the ridge to all others, including other property owners, is adversely affected. This can occur if the proposed structures are poorly placed or if the accompanying landscaping is completely unrelated to the natural setting of the surrounding properties. In addition, other features of the development such as roads,power lines and storage tanks can degrade the scenic quality of an area if they are not carefully designed, located and landscaped. .10600 Properties with scenic resources which are already designated for open space use should be protected through strict land regulations and,on occasion,through acquisition. maim For scenic areas that are planned for some amount of development, the application review process shall consider the feasibility of preserving or protecting the scenic qualities of the site. The County Planning Agency shall be responsible for determining the extent and practicality of preserving such resources. The --- preparation of environmental impact reports can often help to analyze the significance of previously unidentified opportunities. Whenever it is determined to be feasible,scenic features should be protected and maintained,either through land dedication to a public agency or the granting of scenic easements. ... On the other hand, there are man-made facilities, such as non-conforming signs and overhead utility lines, which are unattractive and should be eliminated or abated to enhance the scenic qualities of specific areas in the County. The other major scenic resource of Contra Costa County is the extensive water and delta system of San Francisco, San Pablo,and Suisun Bays. The bays extend along the entire western and northern perimeter of the County. This waterway system provides a pleasant contrast to the land forms of the area. Where the water reaches the shoreline, a mix of land uses occur: salt marshes, railroad tracks, industrial activities, housing and parkland. All add to the diversity and interest of the shoreline. mom Appropriate land uses for the shoreline areas are indicated on the Land Use Element map. All new uses along the shoreline should be reviewed for their impact on the visual and scenic aspects of the bay. Efforts should --• be made to require quality design. The Scenic Waterways designation on the Scenic Resources map below applies to the waterway and its shoreline; the intent of the designation is to draw attention to its scenic character for consideration when reviewing projects. 9-4 9.Open Space i SCENIC RESOURCE AREA MAP Figure 9-1 identifies the major scenic resources in the County,including major ridges and scenic waterways, which should be considered when evaluating nearby development proposals. The County has many smaller,localized scenic resources such as isolated hilltops,rock outcroppings,mature stands of trees,lakes,reservoirs and other natural features. These smaller resource areas are not identified on the map,but they should be reviewed on a case-by-case basis to determine their visual quality. All of these scenic resources should be treated as aesthetic opportunities which should be incorporated into the design of any new development. SCENIC RESOURCES GOALS 9-D. To preserve and protect areas of identified high scenic value,where practical,and in accordance with the Land Use Element map. 9-E. To protect major scenic ridges,to the extent practical,from structures,roadways,or other activities which would harm their scenic qualities. 9-F. To preserve the scenic qualities of the San Francisco Bay/Delta estuary system and the Sacramento- San Joaquin River/Delta shoreline. SCENIC RESOURCES POLICIES 9-10. In areas designated for urban development, the principles outlined below shall be applied in the review of development proposals. 9-11. High quality engineering of slopes shall be required to avoid soil erosion,downstream flooding,slope failure, loss of vegetative cover,high maintenance costs,property damages, and damages to visual quality. Particularly vulnerable areas should be avoided for urban development. Slopes of 26 percent or more should generally be protected and are generally not desirable for conventional cut-and- fill pad development. Development on open hillsides and significant ridgelines shall be restricted. 9-12. In order to conserve the scenic beauty of the County,developers shall generally be required to restore the natural contours and vegetation of the land after grading and other land disturbances. Public and private projects shall be designed to minimize damages to significant trees and other visual landmarks. 9-13. Providing public facilities for outdoor recreation should remain an important land use objective in the County, as a method of promoting high scenic quality, for air quality maintenance, and to enhance outdoor recreation opportunities of all residents. 9-14. Extreme topographic modification,such as filling in canyons or removing hilltops,shall be avoided. Clustering and planned unit development approaches to development shall be encouraged. All future development plans,whether large or small scale,shall be based on identifying safe and suitable sites for buildings, roads and driveways. Exemptions to this policy are appropriate for mining, landfill, and public projects in open space areas. 9-15. In areas along major scenic ridges which are designated for open space use,the principles outlined in Policy 9-19 through Policy 9-26 shall apply. 9-16. New water tanks that would harm the visual quality of a scenic ridge shall be buried,camouflaged or screened to mitigate their impacts. 9-17. New power lines shall be located parallel to existing lines in order to minimize their visual impact. 9-5 • � 1ci � f !� 10 r r v1 �b u in $'U W/f C4us 4 3 00 4n r $ rE j F U t � ENO Rd LAJ o ; 4 � � r� Q L QQ ow W •� '✓ ,� a A 42 --' � f � cn r f rte, r � M or • ,� i� W v .•.

When development is permitted to occur on hillsides,structures shall be located in a manner which is sensitive to available natural resources and constraints. 9-20. Hilltops, ridges, rock outcroppings, mature stands of trees, and other natural features shall be considered for preservation, at the time that any development applications are reviewed. 9-21. Any new development shall be encouraged to generally conform with natural contours to avoid excessive grading. 9-22. All new land uses which are to be located below a major scenic ridge shall be reviewed with an emphasis on protecting the visual qualities of the ridge. 9-23. The involvement of public interest groups shall be encouraged when identifying, acquiring, and maintaining those areas of unique visual quality in the County. 9-24. The appearance of the County shall be improved by eliminating negative features such as non- conforming signs and overhead utility lines,and by encouraging aesthetically designed facilities with adequate setbacks and landscaping. 9-25. Maintenance of the scenic waterways of the County shall be ensured through public protection of the marshes and riparian vegetation along the shorelines and delta levees,as otherwise specified in this plan. 9-26. Tule islands and levee remnants within the County shall be restricted from new development. 9-27. Physical and visual public access to established scenic routes shall be protected. SCENIC RESOURCE IMPLEMENTATION MEASURES 9-a. Prepare specific plans and/or adopt an ordinance which would delineate the boundaries of and protect the major scenic ridgelines not already under public ownership. 9-b. Carefully study and review any development projects which would have the potential to degrade the scenic qualities of major significant ridges in the County or the bay and delta shoreline. 9-c. Develop hillside and ridgeline design guidelines to provide better guidance for development, particularly as it relates to grading,massing and relationship of structures to ridgelines. 9-d. Where possible, structures shall not be built on the top of any designated scenic ridgeline. 9-e. Develop and enforce guidelines for development along scenic waterways to maintain the visual quality of these areas. 9-f. Prepare a corridor study in which an appropriate scenic corridor width will be defined along all proposed scenic routes. 9-g. Prepare a visual analysis of proposed scenic routes to identify views of significant visual or cultural value. 9-h. Identify and designate "gateways" within the scenic routes which are located at unique transition points in topography or land use and serve as entrances to regions of the County. 9-7 9.Open Space 9.7 HISTORIC AND CULTURAL RESOURCES mom INTRODUCTION Northern California has been occupied for at least the last 10,000 years. The early inhabitants have been identified as the Paleo Indians who were nomadic, using primarily large pointed tools for hunting and -D collecting seafood. It is assumed that the Bay Area was inhabited from 5,000 to 10,000 BFA pftexiefflmv'years ago;however,no sites have been identified. With the sea level stabilizing,the Bay and Delta were substantially formed. The subsistence pattern of the early inhabitants shifted with emphasis placed on acorn processing and hunting. Trade increased and tools and ornaments were more abundant as well as refined. Between 2,000 and 5,000 Bpvars ate, cultural patterns were established in large villages along the shoreline and inland permanent streams throughout the Bay Area. The population grew rapidly and a complex society developed. The beginning of the cultures that were in place at contact with the Spanish was approximately 1,500 "years a�4-ro. This period saw the continuation of the growth of economic specialization and the introduction of the bow and arrow. The three groups that inhabited Contra Costa County,the Coastanoan(Ohlone),Bay Miwok and the Northern Valley Yokuts, established their territorial boundaries. Prehistoric evidence indicates that perhaps the Yokuts,were the last to arrive in the Bay Area. The Coastanoans inhabited the western hills,plains and the Bayshore from Carquinez south to Salinas. All of the village sites were associated with a permanent source of fresh water. Many were at the mouth of streams along the Bayshore,but a number of villages were established inland along permanent streams at the base of the hills at the 50 to 150 meter elevation,as evidenced by the many sites which have been identified. Special use and seasonal use sites were established throughout the Coastanoan territory,often in association with rock outcrops or abundant food sources. The Bay Miwok settled along the western slopes of the Diablo range,the inland valleys and on the northern coastal plains. Their largest villages were located in the San Ramon Valley. The Northern Valley Yokuts settled along the eastern slopes of the Diablo range to the San Joaquin River. Their primary villages were along the San Joaquin River with only scattered use of the eastern plains and smaller secondary villages in the inland valleys. In 1776 Mission Dolores was established in San Francisco. Cultural subjugation,plagues and the subdivision of the area into ranches largely destroyed Native American lifestyles. Historical sites and landmarks are unique reminders of the social, economic and political history of Contra Costa County and may serve as sources of private investment and places of public recreational and educational activities. There are many local historical societies and organizations within the County which have been organized to preserve sites, structures and natural features which exemplify aspects of the history AMOK of a particular area of the County as a whole. These groups play an active role in increasing the level of appreciation and awareness of the County's many historical resources. Many historical structures in the County are also listed on the National Register of Historic Places,as well as with the State of California Office of Historic Preservation. Many communities have also established architectural standards or forms of regulation or controls, such as zoning, which require preservation of historical structures and landmarks during the development process. *mom MAP OF HISTORIC AND CULTURAL RESOURCE AREAS Archaeological Resources A systematic archaeological survey has not been conducted for Contra Costa County. There are, however, approximately 600 archaeological sites within the County which have been recorded with the Archaeological Inventory,Northwest Information Center at Sonoma State University. Identification of these archaeological OMNI* 9-8 9.Open Space sites is largely the result of sporadic surveys conducted in association with development proposals. Large areas of the County that have been retained in agriculture have never been surveyed and may yield prehistoric settlement patterns. An archaeological sensitivity map has been prepared(see Figure 9-2). This map conceptually illustrates areas of varying archaeological sensitivity within the County and is intended to be used as a planning tool for determining future survey requirements imposed upon development applications. The sensitivity map has been divided into five categories: (1)extremely sensitive(known sites); (2)highly sensitive(high probability for potential sites);(3)medium sensitivity(possible sites);(4)moderately sensitive (higher probability of subsurface resources,due to deposition);and(5)low sensitivity(mainly the ridgetops). These categories and the reasons for designation are described below. As indicated previously,over 600 sites have been identified in Contra Costa County and wherever these sites have been located,an extremely sensitive designation has been applied. Areas near water are considered most likely to contain an archaeological site(s) and have been designated as highly sensitive. This designation includes stream courses because the native groups would have established settlements or seasonal sites along permanent and seasonal streams. Thus the streams provide potential prehistoric and historic resources. Accessible areas near water were designated to have medium sensitivity. This includes the plains areas between two stream corridors. These areas were used for hunting,butchering camps,hunting blinds or food processing sites. The next level of sensitivity, identified as moderately sensitive, generally encompasses the plains and Delta area. This category is divided into two areas: an area showing surface manifestation of use and an area where indications of prehistoric use would most likely be buried. Because of the deposition that has occurred' this part of the County,subsurface monitoring should be conducted as a condition of project approval. The areas designated as low sensitivity may contain special use sites and would not require as intense an archaeological reconnaissance as required with the above categories. However, as a condition of project approval for projects proposed in this designated area, a reconnaissance should be conducted. This would entail an archaeologist to scan a site for outcrops,caves,quarries,etc.,which may have the potential to Yield further information. Substantial areas within Southeast County have been identified by various governmental agencies and knowledgeable individuals as containing both unique biological habitats, scenic values, and significant archeological resources. Specifically,on;P1rL-i,:vaAe.,1A,r Nervvxla land east of Vasco Road caves have been created by the wind in sandstone cliffs overlooking the San Joaquin Valley. These caves were used by some of the County's earliest inhabitants, and valuable Native American artifacts have been discovered. In particular, well-preserved petroglyphs (Indian paintings) have been discovered in the caves, as well as numerous middens in the adjacent area. Both public and private stewardship of the resources on-site shall be considered as long as the protection is long term and guaranteed in some manner. The acquisition of lands in these areas by the CC'1Q_F1%11&:AAt%1:1 z i�ar the Piast .7 A.%XA &J.Aww %. G-®rfl4ch"a C.-3keNS-ita.Ai.m....er.-iffiast Bqy'Regional Park District,and acquisition of watershed lands by the Contra Costa Water District, may wi I I aid in the permanent protection of some of these archeological resources. Due to the fragile nature of some of these resources,public access to the areas should be limited or restricted in some cases. To facilitate a better understanding of the unique archeological and natural resources in the area, a detailed inventory should be prepared. Efforts to secure financing for such an effort should be explored upon adoption of this plan. 9-9 f F r Qa a.' • •r:fir jfj{.jj��(Jjjr c� •a .. z+ _ •. .'•.tyyr .,r� r • :thy '.�. .�`:•+.�,M$ r' ��� �...�+.

While the historic resources inventory is not considered to be a comprehensive listing of the County's historic resources, it is a major starting point for the protection of historic resources. HISTORIC AND CULTURAL RESOURCE GOALS 9-G. To identify and preserve important archaeologic and historic resources within the County. HISTORIC AND CULTURAL RESOURCE POLICIES 9-28. Areas which have identifiable and important archaeologic or historic significance shall be preserved for such uses,preferably in public ownership. 9-29. Buildings or structures that have visual merit and historic value shall be protected. 9-30. Development surrounding areas of historic significance shall have compatible and high quality design in order to protect and enhance the historic quality of the area. 9-31. Within the Southeast County area, applicants for subdivision or for land use permits to allow non- residential uses shall provide information to the County on the nature and extent of the archeological resources that exist in the area. The County Planning Agency shall be responsible for determining the balance between the multiple use of the land with the protection of resources. HISTORIC AND CULTURAL RESOURCE IMPLEMENTATION MEASURES Development Review Process 9-i. Develop an archaeological sensitivity map to be used by staff in the environmental review process for discretionary permits to determine potential impacts upon cultural resources. 9-j. As a condition of approval of discretionary permits,include a procedure to be followed in the event that archaeological resources are encountered during development or construction. Ordinance Revisions 9-k. Review existing County ordinances and guidelines and make amendments as necessary to ensure that they provide adequate safeguards for archaeologic and historic resources. 9-1. Develop design guidelines for areas adjacent to or within scenic corridors or historic sites. Other Programs 9-m. Promote the use of the State of California Historic Building Code to protect historic sites in the County. 9-n. Encourage owners of eligible historic properties to apply for State and Federal registration of these sites and to participate in tax incentive programs for historic restoration. 9-0. Seek coordination and cooperation with Federal,State,and local governments,and with private and non-profit organizations, to establish finding sources to preserve, restore, and enhance unique historic sites. Such funding sources may be used to acquire and preserve sites or to acquire easements over sites and building facades. 9-p. Identify funding mechanisms, including funding from the County to the extent possible,to support programs to preserve,restore,and enhance unique historic sites. 9-11 9.Open Space 9.8 PARK AND RECREATION FACILITIES INTRODUCTION A recreation component of the General Plan is required to plan for the recreational lands and facilities necessary to meet the needs and desires of the community, while coordinating these plans with the other elements. State law requires that a recreation component be adopted for a jurisdiction to be able to exercise a emu" subdivision parkland dedication ordinance. Maps and Descriptions of Parks and Recreation Facilities This parks and recreation plan is divided into separate sections addressing major parks and open space areas, local parks, and trails. Major Parks and Open Space Areas. The provision of major parks to serve the urbanized areas is essential to the physical and mental well-being of all segments of their populations,as these parks form alternatives to the often intense pace of urban life. Major parks provide areas where people can enjoy active and passive recreation not otherwise available, such as nature studies,camping,or just observing the natural landscape. The preservation of lands for outdoor recreation also assists in the conservation of the County's unique natural, scenic,or cultural resources.Such preservation provides for recreational opportunities while helping to maintain the quality of life for county residents and visitors. Major park facilities in the County are owned by the Federal and State governments, along with an extensive system operated by the East Bay Regional Park District. Additionally, there are some municipal facilities which are major parks as well as water district watershed recreation facilities. For the purpose of this portion of the Plan,the following definitions shall apply: Major Parks are intended to provide a broad range of recreational opportunities,which may include hiking,bicycling, equestrian use,fishing,swimming,camping or group sports,etc. Preservation of historical structures also is included within this grouping. Major Open Space Areas are lands within public or land trust ownership of significant undeveloped areas. The major purpose of these areas is to protect the uniqueness ofthese lands through passive recreational activities and habitat uses that do not require substantial facilities or irnprovenwnts. Agriculture is an cq4xc4x ate,secmdaryuse. The existing and proposed Major Parks and Major Open Space Areas are shown on Figure 9-3. While major parks usually cover areas over 100 acres, shoreline and marsh areas may be much smaller, reflecting the unique areas they protect. With recent voter approval of State and regional park bonds,this plan anticipates the expansion of existing major park and open space facilities. The two primary agencies administering major parks in the County are the State Department of Parks and SWAM Recreation and the East Bay Regional Park District. The State Department of Parks and Recreation tWeowlls three parks-;--. Mt. Diablo State Park Cowell Ranch State Historic Park, and Franks Tract State Recreation Area. These parks are intended to serve the population of the State as a whole,not just residents of Contra Costa County. A small portion of the East shore State Park extends into the Co The East Bay Regional Park District encompasses all of Contra Costa County and most of Alameda County. The district currently maintains--'Wnumerous parks within or .,p artially within the County,performing the function of providing major park facilities which is normally undertaken by county government. They maintain parks in differing types which are classified as Regional Parks, Regional Preserves, Regional Recreation areas,Regional Shorelines,Regional Wilderness Areas and Regional Open Spaces. These facilities are included within the major parks definition, R& P4-4opual Wil4ampa.-Q A ."ba z 41-hiall aria '1146-44i withirl thip h4aicw onaws 40-10 4 waca JAC43:34i"4= W"&-Fq 7 T A JL JL -&-&%41%0 AA 2 W A%-# T V&%.A A JLA A t A A%op A V AL q6tp%J A %.1tM4%1%0'A • WONW&A 9-12 its;re > Nr. � w ti_ r f- 1� Aw E3 OW w 1w �0 H , LI, ® e ,-- p 8 El E3 El El E3 Ej- NOW El El i J►♦�� !##;####rte►#+ �,.�.�#�,4 Mj s p r • _� ®} 9.Open Space There are other agencies which operate major park facilities within the County. The U.S. National Park Amoft Service operates the John Muir National Historic Site in Martinez and the Tao House in Danville. The East Bay Municipal Utilities District owns substantial acreage of open space lands,some of which has a secondary recreation function, e.g., Lafayette and San Pablo Reservoirs. The Contra Costa Water District operates -- recreational facilities on its I.,as Vaqueros Reservoir watershed lairds Additionally, the cities of Pittsburg, Walnut Creek and Concord operate facilities which serve a major park function. While no county standard is included for Major Parks or Open Space areas,there are numerous areas within the County which deserve to be placed in new parks or added to existing ones. This plan endorses the expansion of Major Park and Open Space Areas to protect the unique resources of the County. 7 1 1 1 1 MetedT . There are other locations within the Southeast County area which have potential for development of major new recreational facilities;however,plans for their acquisition are just now being realized. At the time that the East Bay Regional Park District or another public agency is prepared to consider seriously the establishment of such facilities, these proposed facilities should be reviewed by the County to ensure compatibility with the concepts found in this plan and with adjacent existing land uses. Afae.EHLg tlafteT' « ... Local Parks. Local parks are areas of open space set aside for recreational use and are located within an acceptable distance from the people they serve. They serve as the focal points for neighborhoods and communities where people can meet and enjoy their leisure time together. Local parks provide a visual counterpoint to the often intense developed areas in which they are located. The more intense the devel- opment,the greater the need for adequate parks. This plan for local parks specifies the County's standards and general locations of existing and proposed facilities. While the map of local park facilities (Figure 94) shows a county-wide distribution, it has an enforceable effect for the unincorporated area only. Where differences exist between this plan and those of a -•- city,the city plans will take precedence within incorporated areas. For the purpose of this plan, local parks are differentiated into neighborhood and community parks. -- Neighborhood parks generally have service areas equivalent to elementary schools, while community parks more commonly are equivalent to high school service areas. The size and location of local parks will vary depending on the population density of the area to be served. The size of a park will vary with the population to ,N•,,, be served. The greater the proposed population,the greater the size of the park necessary to serve a given area. County park standards for local and community parks and types of play areas are shown on Table 9-1. Most local parks are currently located within incorporated areas. The County requires that special units of government,e.g.County Service Areas,be established to maintain these local facilities in the unincorporated areas. #— County Service Areas are preferred over autonomous units of government, due to the ease with which their boundaries can be modified or eliminated during incorporation. In areas planned for development, efforts .00010 should be made to encourage new County Service Areas to provide for maintenance of local parks. 9-14 t � i i � r^ i � � ■ • My U ■ 16• -'' ■ '� f O ' • ■ '' * N��eh ad r - ■ � V�kk t ■ f ■ U lu 1 r ! � r ■ o. ■ r r / ■ ENO1 t r r r r ■ i iMen ■ * �r ■■ J ■ ■■ IA • ■ w ■ % ■ t %% ■ t ■ • t ■ � ■ • o 1 r t i t cl1 •. � r Y O >` a. p en r' • cis '0 0 O 0 Cd O O ■ a- O ,m .0 0o z • E OD ■ w E O L O U ■ a p Q. 1 ■ O Q '�y O � CL Z o- cc ■ ' / of " O � O Cc U Z J Page 'V'" 9-15 w a~ 9.Open Space MOMM TABLE 9-1 COUNTY PARK CRITERIA 1.

Most trails in the County are established for recreational use, though increasingly some are utilized for commute and transportation purposes. As such this plan is functionally also a part of the County's Transportation and Circulation Element.Note that there are additional policies relating to the transportation aspect of on-street bikeways and trails in the Transportation and Circulation Element.This plan is divided into three separate components dealing with equestrian,hiking and bicycle facilities. In many cases,trails can be utilized for more than one purpose. For ease of presentation,these three trail plan components are discussed and mapped separately. While the trails plan is county-wide and relies heavily on municipal plans in these areas,not all trails within those areas are shown;only the regional links are included. This plan encourages development of local feeder trails and paths to provide an interconnected system which can work as a circulation component as well as providing recreational opportunities. The County Trail Plan focuses on non-motor oriented facilities in order to maintain peace and tranquility for its users. Some trails are shown on all three maps to imply multi-use trails. Alcp trailQ aria izlan"1911:fljo--ar The Bicycle Trails Plan is shown on Figure 9-5. ' fui 1409rej type ALJ.'h.q%W nAt following definitions are to be used in this plan: ruk e Bicycle Trails. Trails of this class connect residential neighborhoods and major destinations of bicycle traffic. They will normally accommodate high volumes of short distance traffic as well as inter-community movement. "'I "hen feasible bicycle paths between communities &A are exp esec.]encouraged.to,be developed on their own pathways which are physically separated from other trails or from vehicular traffic. The Hiking Trails Plan is shown on Figure 9-6. The following definitions are used in the plan: Hiking Trail. All trails included in this plan are major, or primary, trails. These are intended for external travel by individuals or groups of varying skills and ages. They typically connect important trail use destinations such as major parks and points of special interest. Hiking trails may be paved or,preferably, surfaced with resilient materials to keep down dust and permit travel in all weather. The Riding(Equestrian)Trails Plan is shown on Figure 9-7. The following definitions are used in the plan: Riding Trail. All trails included in this plan are major, or primary,trails. These are intended for extended travel by riders of varying skills and age groups. They typically connect important trail use destinations such as major parks and points of special interest. Riding trails usually are not paved, but preferably are surfaced with resilient material to keep down dust and permit travel in all weather. Staging Areas. Staging areas are facilities for the assembly of trail user groups and for the parking of vehicles and accessory vehicles such as horse trailers. They need to be located adjacent to both trails and access roads. These areas also should be considered to be trail features and installed by either trail-providing agencies or the user groups. This is not a complete mapping of areas but an initial listing. Sppgific locations are not shomai on Figure 9-7 but will be resolved as part of the trail planning rocess. Private Recreational Facilities. Increasingly,private developments are being considered which provide on- site recreational facilities to serve project residents. These facilities provide project amenities and are effective sales tools. They may limit the effect of new homes on the existing public park facilities; but, generally,they provide compatible facilities to those of the public parks. For this reason,credit from the park dedication ordinance requirements should only be given where it is clear that private developments provide facilities which are open to and serve the public. This plan encourages the placement of such facilities in private developments and encourages the development of pathways that are integrated in location and design with those of adjacent projects. 9-17 l �OOOt Ar O,j A ON = ♦00.►0 ♦ ,- /���/��i�,.. � 0000 >OOOvO�♦s ►� ,� J � ►000 0000000♦ � . � -{ 1� ■��•i�`.*.� '� `00000+��+0*+�•►i�j�++00+++v+� - " � 0000 ~00000 •00+000'+4'00+0 � �100+00�►�r•)OO�t�00�►OOOOOt 110 A 000 0OVA ♦000 00000+0 40t NO r�� 1w:W1 IN q ♦ `Rai ' .0000 X00♦0 �0�0�•�i► it ►Of��.- - ,0♦000+OO�r�i r0♦ - MWA CA Awl ►.idol i AW i Page• - -r • t# •7 40 MAW r• 10, „M r { .

Where the public health can be guaranteed,the preservation of these areas for recreational and open space purposes should be considered. In appropriate locations,the provisions of outdoor recreational facilities,e.g.private campgrounds,could add to the recreational diversity of the County. Design of such facilities needs to be of a high standard to be com- patible with the adjacent rural environment. There are resource areas within the County,e.g.,the San Pablo Bay and throughout the Delta,where substantial potential exists for private recreational development. These should be encouraged if the projects include programs for environmental enhancements to their immediate areas and are limited to extensive recreational facilities. Additional marinas to serve the Delta and the Bay may be permitted in select areas if they meet the criteria included in the following"Implementation" section. The joint use of recreational facilities is encouraged. For example,significant potential exists for trails to be developed along PG&E and utility pipeline rights-of-way. The County's role in park and trail planning covers a broad spectrum of concerns. The County prepares plans for recreational facilities that serve the County population as a whole and work toward coordination of park and recreation efforts of Federal,State,regional and local agencies. At the same time,the County is directly responsible for recreational planning for the unincorporated communities. In order to ensure that the recreational needs of present and future residents of the County are provided for during the Planning period,the following goals and policies were developed. PARKS AND RECREATION FACILITIES GOALS 9-H. To develop a sufficient amount of conveniently located, properly designed park and recreational facilities to serve the needs of all residents. 94.

SAFETY ELEMENT 10.1 INTRODUCTION In accordance with the State General Plan Guidelines,the safety element includes maps of known hazards including seismic and other geologic hazards,and other hazards described below. It addresses evacuation routes; peak-load water supply requirements; and minimum road widths and clearances around structures,as they relate to identified fire and geologic hazards. Other locally relevant safety issues,including hazardous materials spills and water quality protection are also discussed in this element. The County Hazardous Waste Management Plan( )is incorporated herein by reference,and the goals and policies of the HWMP related to the Safety Element are stated in this section. LEGAL AUTHORITY As directed by the State legislature, this element of the General Plan is intended to further "the protection of the community from any unreasonable risks associated with the effects of seismically induced surface rupture, ground shaking,ground failure,tsunami,seiche,and dam failure;slope instability leading to mudslides and landslides,subsidence and other geologic hazards known to the legislative body;flooding,and wild land and urban fires (Government Code Section 65302(g))." (Useful Safety Element definitions and information maybe found at the end of this element.) In this General Plan,flooding and flood control are discussed in more than one element. For information,goals and policies regarding these issues,the reader is directed to Sections 7.8,Drainage and Flood Control;and 10.8,Flood Hazards. This element identifies the hazards that Contra Costa County and its cities must consider when making land use decisions. Based on analysis of local hazards and an evaluation of their associated risks to life and property,this element recognizes a degree of acceptable risk and contains policies for risk management. The element also provides the basis for planning and coordination of risk management with other divisions of County government, the incorporated cities,and State and federal agencies in order to ensure that public projects,plans and programs of other government agencies reflect public safety issues for Contra Costa County residents. 10.2 RELATIONSHIP TO OTHER ELEMENTS The Safety Element is expected affect land use policies and hence is coordinated with the Land Use Element. Safety considerations may affect the Open Space/Conservation and Public Facilities/Services Elements,and may present additional justification for lowering density in conjunction with land use decisions,based partly on seismic and landslide risk. The Safety Element is also related to the Housing,Circulation and Transportation;and Public Facilities/Utilities Elements in that it discusses hazards that may affect decision-making in these issue areas. 10.3 RELATIONSHIP TO OTHER GENERAL PLAN DOCUMENTS The goals, policies and implementation measures contained in this element are intended to guide planning for public and private projects that are subject either to approval of the County planning agency, or to review by County staff,although they may be under the jurisdiction of other public agencies operating in the County. Such goals,policies and implementation measures are intended to be consistent with the other elements of the General Plan,as well as with other planning documents,including the County HWMP(1988). 10.4 GENERAL PUBLIC SAFETY ASSUMPTIONS The concept of public safety expressed in this element, and the proposed policies and programs to achieve a suitable degree of public protection,are based on the following assumptions: 0 Hazards are an unavoidable aspect of life. Not all hazards can be eliminated,nor can every degree of risk be eliminated for any specific hazard. 0 Public policy and action are appropriate measures to mitigate significant hazards to the general public or to a large part of the population. Such hazards may have a relatively low risk of occurrence but would be 10-1 10.Safety Element disastrous should they occur,or they may have a relatively high risk of occurrence,such as minor landslides, but would not be disastrous. Hazards of the latter type can be due to persistent safety problems in the County. 0 Through the dissemination of information and public discussion,satisfactory judgments can be made as to the levels of monetary,environmental and social costs appropriate to mitigate hazards to public safety. The policies of this element are not intended to remove all risks associated with the specific hazards discussed,but when implemented will reduce risks to life and property from certain natural and man-made events and conditions, and will lead to greater life safety in case of general disaster. The determination ofacceptable and unacceptable risk requires judgments based onweigiungseveral,factors including the nature of the hazard,the frequency,or risk,of damaging event associated with the hazard,and the relative numberofpersons exposed to the risk. The degree or intensity of any specific hazard is a major consideration in public mitigation efforts.Thus,hazards with a high life-loss potential are less acceptable than hazards which primarily affect properiy,and hazards which could impact entire communities are less acceptable than hazards which may impact relatively few persons.Onlymininlal risk to critical facilities and functions(including water supply,en ency services,evacuation routes,and medical and mass care facilities)is considered acceptable since these facilities and functions are critical to disaster recovery for entire communities. Exposure to the natural hazards considered in the Element is often voluntary, persons who choose to purchase property on unstable ground or subject to wildfire and flooding are usually aware of the potential hazard. On the other hand,exposure to mono some risks,such as exposure to hazardous substances,is usually involuntary. Voluntarily taken risks are not necessarily ac- ceptable from the public point of view because property owners have expectations that grading and building regulations,fire services,and flood control works will provide a significant degree of risk reduction. The greater capital and maintenance costs of public facilities in hazardous areas,represent a disproportionate share of tax revenues for hazard mitigation. 10.5 SAFETY ELEMENT ORGANIZATION This chapter of the General Plan is divided into six sections that present background information,policies,maps, and implementation measures regarding: 0 seismic hazards(earthquakes and faults,and the effects of strong earthquakes,such as liquefaction); -- 0 landslides and associated hazards; 0 flooding hazards,including the impacts of the"greenhouse effect,"subsidence,and dam or levee failure; 0 hazardous material uses,including the transport and storage of hazardous materials,pipelines,etc.; 0 dangers to water quality and public water supplies;and 0 disaster planning and the provision of public protection services. 10.6 SEISMIC HAZARDS INTRODUCTION Earthquakes are sudden releases of strain energy stored in the earth's bedrock. The great majority of earthquakes are not dangerous to life or property either because they occur in sparsely populated areas or because they are small earthquakes which release relatively small amounts of energy. However,where urban areas are located in regions ,..., of high seismicity, damaging earthquakes are expectable if not predictable events. Seismic risk is assumed by every occupant and developer in Contra Costa County because the County is within an area of high seismicity;the San Francisco Bay Region has been impacted by more than ten severe earthquakes during historic time. The major effects of earthquakes are ground shaking and ground failure. Severe earthquakes are characteristically accompanied by surface faulting and less commonly by tsunamis and seiches, further described in the "Flood Hazards" section of this chapter. Flooding may also be triggered by dam or levee failure resulting from an mum earthquake, or by seismically-induced settlement or subsidence. All of these geologic effects are capable of causing property damage and,more importantly,risks to life and safety of persons. A fault is a fracture in the eax's crust along which the rocks on opposite sides have moved relative to each other. By definition, active faults have a high probability of future movement. With regard to planning and development,two aspects of fault displacement should be considered: (a)the effects that sudden movement along faults may have on structures built across their traces,and(b)the relatively slow effects of fault creep on structures built across their traces.Fault displacement involves forces so omft great that the only means of limiting damage to manmade structures is to avoid the traces of active faults. Any movement beneath a structure,even on the order of an inch or two,could have catastrophic effects on the structure and its service lines. 10-2 10.Safety Element Energy release events on an active fault may alternate from one trace to another,and movement on a master fault may trigger adjustments on minor, subsidiary faults. Because of these factors, fault traces which intersect or parallel known active faults warrant special consideration during project review. For the purpose of this Safety Element,earthquakes are classified according to the descriptive names listed in Table 10-1. TABLE 10-1 EARTHQUAKE SIZE DESCRIPTIONS Richter Descriptive Title Magnitude Intensity Effectsr Minor Earthquake l -3.9 Only observed instrumentally or felt only near the epicenter. Modified Mercalli Scale,intensity IV or less. Small Earthquake 4-5.9 Surface fault movement is small or does not occur.

Moderate earthquake 6-6.9 Moderate to severe earthquake range;fault rupture probable. Major earthquake 7-7.9 Landslides, liquefaction and ground failure triggered by shock waves. Great earthquake 8-8+ Damage extends over a broad arra, depending on magnitude and other factors. Maximum intensity ranges from VIII to XII on the Modified Mercalli Scale. Source: Compiled by Contra Costa County Community Development Department. Earthquake planning and seismic review often use a set of descriptions of predicted earthquake capabilities called "maximum credible earthquake"and"maximum probable earthquake." The maximum credible earthquake is the maximum earthquake that appears capable of occurring. The maximum probable earthquake is the maximum earthquake believed likely to occur during a 100-year interval. The maximum credible and maximum probable earthquakes for various faults in the county are defined later in this chapter. The overall energy release of an earthquake is its most important characteristic,but not the only criterion required for seismic safety planning or construction design. Other important attributes include an earthquake's duration,its related number of significant stress cycles and its accelerations. Structures capable of withstanding more powerful earthquakes can fail in a less severe earthquake of long duration or due to especially high local accelerations. Local Geology In order to understand the fault system in Contra Costa County,where earthquakes are most likely to occur,a brief discussion of the local geology is necessary. Figure 10-1 illustrates the generalized geology of the County and the accompanying Table 10-2 summarizes the County's"geologic column"and geologic time scale. The geology of Contra Costa County is dominated by several northwest trending fault systems which divide the County into large blocks of rock. For example,the Briones Hills are bounded by the Hayward fault on the west and elements of the Franklin-Calaveras fault system on the east. Within a particular block the rock sequence consists of(1)a basement complex of broken and jumbled pre-Tertiary sedimentary,igneous and metamorphic rocks;(2)a section of younger Tertiary sedimentary rocks and some volcanic rocks(flows and tuffs)which locally intertongue with and overlie the sedimentary section; and (3) surficial deposits including stream alluvium, colluvium (slopewash deposits at the foot of steeper slopes), slides, alluvial fans, and Bay Plain deposits. The character of each of these categories of rocks is summarized in Table 10-2. 10-3 10.Safety Element TABLE 10-2 --- GEOLOGIC TIME SCALE GENERALIZED STRATIGRAPHIC SECTION AND LITHOLOGIC CHARACTERISTICS Generalized Stratigrayhic Section Geologic Age (Absolute Age)' Formation Name General Lithologic Description QuaternaryAlluvium .� Includes all types of alluvial deposits.

Note: This table is generalized from original source materials. It is not an indicator of ground conditions on individual sites. From the perspective of seismic safety planning,the older,coarser,and well-drained materials tend to be stable during earthquakes,while younger,fine-grained and water-saturated deposits tend to be less stable. Colluvium is mom often marginally stable to unstable. A disproportionate share of landslides originate in colluvium. Faults are seldom single cracks but are typically a series of quasi-parallel or en-echelon breaks that comprise zones. These ..,, breaks form networks composed of major and minor faults. A fault having recorded movement,or one which shows evidence of geologically recent displacement(within about the last 4-811,000 years),is regarded as"active"and is more likely to generate a future earthquake than a fault which shows no signs of recent movement. Along with the criteria for fault activity,the last time of faulting,based on geologic evidence,is used to access fault activity. The historic record is so MOM short,and earthquakes are so scattered,that they are used only as the surest indicator of fault activity. 10-4 w- A 10.Safety Element General Inventory of Seismic Faults "" Figure 10-2 shows the earthquake faults that have been mapped in the County and categorizes their recent activity.

It is to be regarded as a probable occurrence,not as an assured event that will occur at a specific time.(CDMG Note 43,1975). In the context of geologic evidence for activity,those faults which have been active during the Holocene period, approximately the last 4-011,000 years,are considered to be active faults,and those faults which have been active during the Quaternary period,approximately the last-34.6 million years,are considered to be potentially active faults. MOM This serves to differentiate faults for which sufficient evidence of recent activity has been noted to explicitly include them as known geologic hazards,distinct from those faults for which recent displacement is known or suspected,and whose latest activity has not been determined,but may have been within approximately the last 4-011,000 years. In addition to faults which have been classified as active or potentially active,there are others whose activity has not been clearly established by presently available information. Some of these faults are shown on Figure 10-2 - ". Others remain to be studied. Specifically,there are numerous thrust fault*S ui the County that,present,ui apparend ,1my risk of surface fault rupture but are potential.seismic sources.

Six major Bay Area earthquakes have occurred since 1800 that definitely affected the County,and at least two of the faults that produced them run through or into the County. These earthquakes and the originating faults include the 1836 and 1868 earthquakes on the Hayward fault,and the 1861 earthquake on the Calaveras fault. Two earthquakes, in 1838 and 1906,originated on the San Andreas fault,west of the county near San Francisco or to the south,while one earthquake(with two major shocks)that caused some damage in the County occurred in 1872 and was centered north of Contra Costa County in the Vacaville-Winters area of Solano County. These latter events likelx occurred on a thrust fault and are not known to have been accoinpanied by sufflace fault rupture. A smaller earthquake,centered near Collinsville in Solano County on a fault of uncertain identity,occurred in 1889.-- }e-I[ _ -, ions, fe I i teN. eas Sinai]as"':%:r 2.0 beeawse netall efthttm' •� mere worded-by a -%X mecum%Lo&V e-pe Q3 -98 : Existing Policies and Regulations Affecting Seismic Hazards The major State legislation regarding earthquake fault zones is the Alquist-Priolo Special Studies Zones Act. The purpose of the Act is to regulate development near active faults to mitigate the hazard of surface fault rupture. Under the Act, the State Geologist is required to delineate "sp �' --u seathquake fault zones" along known active faults in California. Cities and counties affected by the zones must regulate certain development projects within the zones.They must withhold development permits for sites within the zones until geologic investigations demonstrate that the sites are not threatened by surface displacement from future faulting. Within Contra Costa County faults that a currently zoned include the Fla ard,Calaveras,Concord and Greenville faults. The Seismic:Hazards Mappine Act the Act)of 1990(Public:Resources Cade,Chapter 7.8,Division 2)directs the Califoniia Department of Conservation (DOC), Division of Mines and Ge010f (DMG) rnow called California (:ieolo(ncal Survey(CGS)*]to delineate seismic hazard zones. The purpose of the Act is to reduce the threat to public health and safety and to minimize the loss of life and proyeM by identity ing and mitigating seismic hazards. Cities, counties,and state agencies are directed to use the seismic hazard zone maps in their land-use planning and permittin_� processes Like the Alquist--Priolo Act,projects that fall under the authority of the Seismic Hazards Act are subject to the outcome of comprehensive ggotechnic;al studies. Evaluation and miti2c ation of seismic hazards are to be conducted under guidelines adopted by the California State Mining and Geoloa Board(Sl1-SGB). The Act also directs SMGB to appoint and consult with the Seismic Hazards Mappine Act Ad,%isory Conumttee (,Si-IMAAC)in developing criteria for the preparation ofthe seismic hazard zone maps. SI-FMAAC c;onsisLs of geolo n'sts, seiS111o1o�n:sts, civil and structural engineers, representatives of city and county ,grovenunients, the state insurance c;omxnissione-r and the insumice indusgy. In 1.991 SMGB adopted initial criteria for delineating seismic hazard zonas to promote uniform and effective statewide implementation of the Act. These initial criteria protide detailed standards for mag reyional liquefaction hazards. They also directed CGS to develop a set of probabilistic seismic neaps for. Califoniia and to research methods that might be appropriate for mapping earthquake-induced landslide hazards. 1 he official Seismic Hazard Maps of Contra Costa County have not Tet been issued,but official maps have been issued for portions of San Francisca,Alameda and Santa Clara Counties,and the mapping of Contra Costa Countyis anticipated in the near future When official maps are issued,the Counter would utilize these snaps to identif�T areas that are deemed to present a risk of liquefaction and seismically triggered landslide hazards that require study. Projected Probability of Seismic Hazard Occurrences Using the available data and information,an earthquake probability estimate has been developed for Contra Costa County and is shown in Table 10-4. Table 10-4 evaluates the likelihood that earthquakes capable of producing damage in Contra Costa County will occur on certain faults during a 50-year period. (Fifty years is a rough average nominal life of a structure.) The forecast shows that a structure built in Contra Costa County is likely to be subjected to a severely damaging earthquake during its useful life. Such an earthquake could originate in several locations. Since a structure built in the region probably will be subjected to a damaging earthquake during its useful life,it is reasonable that it be designed to survive the event, or to at least protect its occupants and functions. To do this, architects and engineers need to have information on earthquake characteristics,such as earthquake accelerations and duration of strong ground shaking. These characteristics have been estimated for selected faults in Table 10-5. The data in the table may be used as an approximation of parameters prevailing over a large area and as a beginning point for determining the parameters affecting a particular location. 10-9 10.Safety Element TABLE 10-4 APPROXIMATE PROBABILITY OF OCCURRENCE OF EARTHQUAKES ON SELECTED BAY AREA FAULTS (50-YEAR PERIOD) Approximate Probability of Causative Fault Magnitude; Occurrence(over a 50:year period) San Andreas 7.0-8.0 Likely 8.0-8.5 Intermediate Hayward 6.0-7.0 Likely 7.0-7.5 Intermediate Calaveras 6.0-7.0 Likely 7.0-7.5 Intermediate-Low Concord 5.0-6.0 Likely 6.0-7.0 Intermediate-Low Antioch 5.0-6.0 Likely 6.0-7.0 Intermediate-Low Definition of Terms: Likely: Greater than a 50%probability of occurrence.

Source,-, Contra Costa County Community Development Department estimates The tabulated earthquake characteristics in Table 10-5 are for"bedrock"for seismic response purposes,and may differ in the near-surface materials. Solid ground or rock tends to dampen ground motion while poorly consolidated and water- saturated materials amplify ground motion. These data should be used only by qualified personnel in project background evaluations,and by engineers and architects in their development of structural design criteria.

Figure 10-4 illustrates the estimated seismic susceptibility to damage based upon this mapping. Areas situated on hard bedrock(e.g. the Briones Hills,Las Trampas Ridge,Diablo Range)may be expected to perform satisfactorily under earthquake conditions,provided that ground materials near the surface do not fail. Areas underlain by weakly consolidated sedimentary rocks (e.g. Pinole Ridge, the Tassajara Area, Alamo) are considered to possess a moderately low to moderate damage susceptibility. The characteristics of ground motion in alluvial areas will differ somewhat from nearby bedrock areas (e.g, higher amplitudes,longer period,,somewhat higher accelerations,etc.),and these differences may be important in the design of sophisticated structures. Areas underlain by firm,dry alluvium are considered to possess a moderate damage susceptibility. Areas underlain by young bay mud and deposits of the Sacramento-San Joaquin delta are considered to possess the highest damage susceptibility. Most of the County's development and population are located in areas of moderate to moderately low damage susceptibility. Liquefaction is a specialized form of ground failure caused by earthquake ground motion. It is a "quicksand" condition occurring in water-saturated,unconsolidated,relatively clay-free sands and silts caused by hydraulic pressure(from ground motion)forcing apart soil particles and forcing them into quicksand-like liquid suspension. In the process,normally firm,but wet,ground materials take on the characteristics of liquids. Catastrophic ground failures may result from liquefaction that pose a major threat to the safety of engineered structures. Major landslides, settling and tilting of buildings on level ground, and failure of water retaining structures have all been observed as a result of this type of ground failure. It should be emphasized that great earthquakes anywhere in the Bay Area are capable of triggering liquefaction in Contra Costa County. Historically,ground failure in its various forms,including liquefaction,has been a problem in areas of continually wet,unconsolidated geologic units. In Contra Costa County,the areas which are most susceptible to ground failure include the geologically young sediments of the San Francisco Bay estuary,including the Delta lowlands. Within the area ofcontinually wet,unconsolidated deposits(Zone IV on Figure 10-4),the degree of seismic risk is closely related to local ground conditions.A site underlain by great thickness ofpotentiallyuristablenwmial(sotiqq Am 1 emsisive mud and loose, clay-free sands,etc.)is extremely hazardous. It should be recognized that such a site has a very limited development potential. Conversely,a site underlain by a minimi thickness of soft mud possesses a much better development potential. Utilizing existing knowledge of foundation engineering, a site could be made suitable for a variety of land uses. Liquefaction presents the potential for the most serious consequences m the Delta. Several pre-development studies have confirmed that a high potential for liquefaction exists below levees and proposed developnents. This potential its the possibility that several failures can occur simultaneously on a single levee,possibly access forrepairs.Floodingof ossi protected islands would then be unpreventable and would make relief and later repair very difficult (A further discussion of flooding and liquefaction in the Delta area is included in the"Flood Hazards"section below.) Figure 10-5 shows the estimated liquefaction potential for the County,based on geologic conditions(summarized in Figure 10-1),and a review of soils data from a number of sources.. This nigp will be utilized until the new official seismic hazard niaps are published and available. Areas underlain by hard bedrock are not subject to liquefaction,so these can be eliminated from consideration when large areas are being evaluated on a generalized basis. In Contra Costa County,such areas comprise about half of the land area,but almost all of that has hilly topography. Areas with deep water tables and those underlain by well consolidated ground materials typically have low or moderate liquefaction potentials. The cities of western,central and northern Contra Costa County fall into these categories. Geologically young and water-saturated sandy sediments,such as those found in the extensive shoreline areas in western and northeastern county locations and the delta,are highly susceptible to liquefaction. Soil engineering studies for subdivision and other major land development projects should make a careful appraisal of the liquefaction potential and the possible consequences of such liquefaction. SEISMIC HAZARD ISSUES In areas of substantial risk,geologic conditions should be a primary determinant of land use. Generally,urban or suburban uses or intensities should not be planned for areas where geologic conditions would result in unacceptable risks to life and safety,and areas where the public costs of overcoming geologic deficiencies would 10-11 10.Safety Element mamma exceed public benefits. It should be recognized,however,that much can be done to mitigate potentially hazardous conditions. Project approvals in areas of substantial risk should be based on knowledge of local ground conditions and appropriate mitigation. Because it is impractical for government to prepare detailed geologic information on a countywide basis,it is preferable to deal with geologic conditions through project review. R hiancata mill U State law(198 6)requires that jurisdictions prepare an inventory of unreinforced masonry structures and adopt local ordinances to improve or replace this type of structure. Unreinforced masonry structures are generally believed to be prone to collapse in an earthquake with resultant high risk of deaths and injuries. This was recently colifinned b-v the Paso Robles eartliquake of 2003. Certain public and institutional services are needed immediately following an earthquake to aid the injured,prevent additional casualties, and protect property. It is imperative that these critical and emergency service facilities survive an earthquake and remain operative. Other public facilities such as emergency shelters and gathering areas for separated family members are also important facilities that should be designed to survive any earthquake. Underground components of utility systems are often extensively damaged during significant earthquakes. Pipelines for domestic and fire fighting water,sewer service,gas,and for electrical services and communications can be shattered. Above-ground transmission and distribution systems are also susceptible to earthquake damage, but they are usually easier and less expensive to restore than the underground installations. In addition,utility plants and stations are subject to earthquake damage. Transportation facilities,especially the bridges,roads and streets of the arterial network,are"critical"or"essential"facil- ities for responding to the effects of a substantial earthquake because they are necessary for the movement of emergency vehicles,supplies,and evacuation transport. Later,they are necessary to accomplish reconstruction and restoration of the local economy. For example,airports enable damage-assessment reconnaissance flights immediately after a disaster,and accommodate the evacuation of casualties and supplies afterwards. The full range of transportation facilities,including railroads,ports,and public transportation system,have roles to play in the recovery process. Transportation systems are vulnerable to earthquakes. Road and streets are easily blocked,and are often buckled and broken, but emergency routes can be readily improvised. The interchanges of freeways and similar installations(bridges and overpasses,for example)are often damaged but not readily restored. A major earthquake impacting Contra Costa County would be expected to cause widespread damage to its transportation systems. The linear elements of these systems—roads,railroad tracks,and BART tracks—necessarily cross various earthquake faults as well as areas susceptible to ground failure. Landsliding from non-earthquake causes is a recurring problem that would be intensified by ground shaking. Critical industrial facilities are of special concern because of potential hazardous materials spillage or critical industrial processes disruption. For critical*industrial facilities,seismic safety considerations must include the location of plants and storage areas,and the design and construction of industrial structures. As a result of compliance with out-of-date building codes,some existing installations need to be evaluated in light of current knowledge. Opportunities and Constraints Table 10-6 details the acceptable risks from seismic events relative to various types of structures by use and occupancy. This 0.nis scale was developed by the California Legislature's Joint Committee on Earthquake Planning and has been adopted in most California building codes and by most California planning agencies. g Following the experience of the San Fernando Earthquake of 1971,building code provisions have strengthened many structural design criteria. However, a major deficiency in the code is the lack of strict criteria governing attachment of non-structural elements which present a danger to persons if they are dislodged during an earthquake. NOMM The major technical impediment to the development ofprograms to correct hazardous structural conditions or"dangerous buildings" is the lack of a comprehensive and systematic inventory. Conventional sources of generalized structural information,such as the Federal Census of Housing and Land Use inventories for the general plan,are not adequate to W"Ab make even large-area policy planning assessments of where problem structures are located,what their problems are,and how many structures are involved. Similarly,normal sources of information on individual structures are*inadequate to provide the kinds of information needed for implementation and enforcement programs. In both cases,special inventories and specialized reviews ofexisting data sources are necessary to prepare seismic safety pro dealing with structures. 10-12 *wow 10.Safety Element TABLE 10-6 A SCALE OF ACCEPTABLE RISKS Extra Project Cost Probably Level of Acceptable Risk Kinds of Structures Required to Reduce Risk to an Acceptable Level 1.

In addition,it is assumed that the structure would have been designed and built in accordance with current California practice.Moreover,the estimated 3 additional cost presumes that structures in this acceptable-risk category are to embody sufficient safety to remain fiinctional following an earthquake. Failure of a single structure would affect primarily only the occupants. These additional percentages are based on the assumption that the base cost is the total cost of the building or facility when ready for occupancy. In addition,it is assumed that the structures would have been designed and built in accordance with current California practice. Moreover,the estimated additional cost presumes that structures in the acceptable-risk category are to be sufficiently safe to give reasonable assurance of 5 preventing injury or loss of life during any earthquake,but otherwise not necessarily to remain functional. Ordinary risk": Resist minor eardxpakes without damage,resist moderate earthquakes without structural damage,but with some non-sbuctural damage; resist major earthquakes of the intensity or severity of the strongest experienced in California,without collapse,but with some structural as well as non- structural damage. In most structures,it is expected that structural damage,even in a major earthquake,could be limited to repairable damage. (Structural Engineers Association of California).

The Post-Earthquake Recovery and Redevelopment Advisory Group to the Legislature's Joint Committee on Seismic Safety has made a series of recommendations which suggest control mechanisms that can be instituted prior to an earthquake, and which will go into effect automatically in the post-earthquake period to provide a framework for reconstruction and redevelopment. The objectives of these recommendations are to minimize recovery problems and maximize the degree of seismic safety afforded to future generations inhabiting the affected area. Evaluation Of Existin Policies 10 -a Plans,Pondes and Regulations This advisory group has recommended that counties and cities provide for post-disaster conditions in the General Plans. First,jurisdictions need to ensure that proper consideration be given to changes in land use in areas that are heavily damaged by future earthquakes. The planning staffshould develop contingency procedures for immediate updating of the General Plan for areas that are heavily damaged by a severe earthquake. Additionally,it is suggested that contingency redevelopment be considered in preparing or updating area plans. 10-13 • . y..• t •+ r •' .� r �_)�s ..'�;Dov(• '4 N = i ..`.•`t .>3:�•, j • 'xf{ n0"kI. .' .•..:•.:�1,•N w�}•t}?.. ••d*.y:..t.^;j::i,�:., • M CC ';Y'#+�� �•. i ':LM.p;�t: .••, 1 :;j+'wj al:iiS '�'r'� =';Fti}•F:t'�F'.=M"t..•.•Snt...wJ�.f3 fdl! f7 ~ L „� •_�'A Ott•••;.. `�, ..' a � w,.•.. +- !

The basic recommendation is that the Safety Element be utilized to its fullest in performing project reviews. It is intended to guide public and private planning for development and public works, emergency operations, post-disaster recovery assistance, and redevelopment. The policies are suggested for consideration by all public,private,and utility agencies in the County which impact on,or can improve the state of public safety,guide public and private planning for development and for public works,emergency operations,post- aw� disaster recovery assistance,and redevelopment. The policies are suggested for consideration by all public,private, and utility agencies in the County which impact on,or can improve,public safety. The purpose of the preceding discussion has been to make observations and preliminary estimates of the prevalence,location and degree of hazard posed by certain types of existing structures and facilities. Furthermore, it is intended to indicate the scope,direction and magnitude of the subsequent review of individual facilities. It is apparent that the highest priority should be given to(a)critical structures(including industrial facilities and high occupation buildings)that are sited in hazardous fault zones,in areas subject to seismically-triggered flooding,and in marshland areas;(b)building types that are know to be hazardous;(c)older structures which have not had the benefit of seismic design provisions. SEISMIC HAZARD GOALS 10-A. To protect human life and reduce the potential for serious injuries from earthquakes;and to reduce the risks of property losses from seismic disturbances which could have severe economic and social consequences for the County as a whole. 10-B. To reduce to a practical minimum injuries and health risks resulting from the effects of earthquake ground shaking on structures,facilities and utilities. 10-C. To protect persons and property from the life-threatening,structurally and financially disastrous effects of ground rupture and fault creep on active faults,and to reduce structural distress caused by soil and rock weakness due to geologic faults. 10-D. To reduce to a practical minimum the potential for life loss,injury,and economic loss due to liquefaction- induced ground failure, levee failure, large lateral land movements toward bodies of water, and consequent flooding;and to mitigate the lesser consequences of liquefaction. SEISMIC HAZARD POLICIES 10-1. Contra Costa County, as part of an area with high seismicity, shall recognize that a severe earthquake hazard exists and shall reflect this recognition in its development review and other programs. 10-2. Significant land use decisions (General Plan amendment,rezoning, etc.) shall be based on a thorough evaluation of geologic-seismic and soils conditions and risk. 10-3. Because the region is seismically active,structures for human occupancy shall be designed to perform satisfactorily under earthquake conditions(see Table 10-6). 104. In areas prone to severe levels of damage from ground shaking(i.e.,Zone IV on Map 104),where the risks to life and investments are sufficiently high,geologic-seismic and soils studies shall be required as a precondition for authorizing public or private construction. 10-5. Staffreview of applications for development permits and other entitlements,and review of applications to other agencies which are referred to the County,shall include appropriate recommendations for seismic strengthening and detailing to meet the latest adopted seismic design criteria. 6-0 10-6. Structures for human occupancy,and structures and facilities whose loss would substantially affect the public safety or the provision of needed services,shall not be erected in areas where there is a high risk of severe damage in the event of an earthquake. 10-7. The County should encourage cooperation between neighboring government agencies and public and private organizations to give appropriate attention to seismic hazards to increase the effectiveness of singular and mutual efforts to increase seismic safety. 10-16 -- 10.Safety Element Groundshaking Policies 10-8. Ground conditions shall be a primary consideration in the selection of land use and in the design.of development projects. 10-9. In areas susceptible to high damage from ground shaking(i.e.,Zone IV on Map 10-4),geologic-seismic and soils studies shall be required prior to the authorization of major land developments and significant structures(public or private). 10-10. Policies regarding liquefaction shall apply to other ground failures which might result from groundshaking but which are not subject to such well-defined field and laboratory analysis. Faults and Fault Displacement Policies 10-11. Classify as active those faults which have ruptured the ground surface during Holocene geologic time, roughly the last 10,000 years.

Slopes may suffer landslides, slumping,soil slips,and rockslides. Reclaimed wetlands,whether filled or not,experience amplified lateral and vertical movements which can be damaging to structures,utilities,and transportation routes and facilities. Landslides and other ground failures occur during earthquakes,triggered by the strain induced in soil and rock by the groundshaking vibrations, and during non-earthquake conditions,most frequently during the rainy season. Both natural and man-made factors contribute to these slope failures. Contra Costa County's damage,costs after a large earthquake could be high in proportion to the State as a whole because of its large area of hilly terrain and high proportion of recent,poorly consolidated geologic formations which are prone to slope failure. Ground failure occurs when stresses in the ground exceed the resistance of earth materials to deformation or rupture. This instability can be triggered by earthquake shaking,which instantaneously places high stresses on earth materials by loss of soil strength due to saturation or seismic shaking. Ground failure can also be triggered by man-made changes,such as loading a steep slope or unstable soils. The manifestations of ground failure are complex and highly variable; they include numerous varieties of landslides,sloughing,liquefaction,ground cracking,lurching,lateral spreading,subsidence and differential settle- ment. Whether ground failure may occur, and the type of ground failure that may develop, depend on the topographic,geologic,and hydrologic characteristics of the ground,as well as the extent of ground shaking. Important effects of ground failure in addition to direct life and structure loss and injuries,include loss of access for emergency services and repairs at important facilities which are accessed by traversing unstable ground,and the potential release of hazardous materials from containment facilities. Landslides are perhaps the most common form of ground failure that is not caused by earthquakes. In areas where a severe slope stability problem exists,landslide damage can best be avoided by simply not building on the unstable ground. In some landslide-prone areas,landslides can be totally removed or stabilized. Through good planning and careful,controlled design,landslide losses can be all but eliminated. Although landslides due to slope failure are most frequent in"wet years" with above-average rainfall,they can occur at any time. Landslides may also occur on slopes of 15 percent or less;however,the probability is greater on steeper slopes,with old landslide deposits being the most likely to experience failure. 10-18 OWN" 10.Safety Element Slope failures are not expected to produce a disaster affecting hundreds or thousands of persons in the County. Rather,there is a persistent risk of damage to public and private property including individual residences,roads,canals and reservoirs,and other facilities. On a county-wide basis,the two most important factors influencing the nance of slopes are the nature of the bedrock or surf cial deposits and the slope angle. However,them are a number of other factors which have a profound effect on the stability of a particular hillside. For example,the presence or absence of deep-rooted vegetation;surface and subsurface drainage conditions;thickness and engineering characteristics of soils and underlying weathered,partially decomposed rock-,orientation of bedding;or locally high rainfall can exert a controlling effect on the intensity ofhatural processes occurring on a particuLv hillside. County General Plans historically have recognized that major slope areas in excess of 26 percent are"not readily developable"and"undevelopable,"recognizing the cost and engineering difficulties of grading steep slopes as well as their inherent unsuitability. This development limit in general agrees with customary limits throughout the Bay Area,and varies only slightly from the 30 percent standard reference developed by the State Division of Mines and Geology as the maximum developable slope. This is a state-wide reference which does not reflect special conditions such as clayey soils prevalent in Contra Costa County. Landslides and ground slippages are another form of ground failure which may be precipitated by significant ground motion produced by earthquakes. Areas that are subject to slides and slippages from other natural causes maybe very hazardous under earthquake conditions. This is also to say that earthquake effects will be more extensive if a major earthquake occurs during the rainy season when ground conditions are favorable to landsliding and ground slippage. Whether a landslide will or will not occur at any specific,presently stable slope usually cannot be predicted under"natural conditions"because ofthe range ofnahn-al conditions and changes which occur with time.However,land which has experienced handsliding in the past is believed to be generally more slide-prone,and also is more sensitive to man­ir0ucW changes,such as Wig, factors. watering removing or changing the type of vegetation,and changing patterns,among many possible Many old landslides reach a position of static stability that may be lost as a result of earthquake shaking. The nearer to "equilibrium"condition the land is during normal conditions,the more likely the equilibrium(stable condition)will be lost during earthquake shaking. It should be noted again,however,that equilibrium may prevail under natural conditions at some times,yet be reduced to marginal stability or instability with different,natural or changed,conditions. Slight changes in equilibrium may result in slow,barely recognizable,landslide movement,and/or movement which periodically occurs under unfavorable conditions. Some landslides can be"turned on and off"by allowing groundwater levels to rise or fall,or by changing the mass of material in a particularly sensitive part of the landslide. Map of Slopes and Landslide Hazard Areas Maps showing degree of slope,landslides,landslide deposits,and relative slope stability(or instability)have been produced by several State,regional,and federal agencies;several such maps cover parts of Contra,Costa County,and others,cover areas as large as the entire nine-County Bay Area.

'x-- 10.8 FLOOD HAZARDS INTRODUCTION .0� Substantial areas within Contra Costa County are subject to flooding. According to records maintained by the Federal Emergency Management Agency(FEMA), the majority of the County's creeks and shoreline areas lie within the 100-year flood plain, i.e., an area subject to flooding in a storm that is likely to occur(according to averages based upon recorded measurements)once every 100 years. The FEMA records are maintained as a means of determining flood insurance rates through the National Flood Insurance Program. i * i In the West and Central County,these areas include portions of the shoreline in the vicinity of Richmond,Hercules,Rodeo,, Crockett,Port Costa,and Martinez;most creeks in urbanized areas,including Concord,Walnut Creek,and the San Ramon Valley-,and reservoirs and creeks located on undeveloped East Bay Regional Park District(EBRPD)and East Bay Municipal Utility District(EBMUD)lands. In the East County,substantial acreage hes within the 100-year flood plain,including Bethel 10-22 k 10.Safety Element Island.,the Veale Tract,Holland Tract,Franks Tract,Jersey Island,and the area in the Byron vicinity.Portions of the Pittsburg, Antioch,and Brentwood areas,as well as a number of creeks in East County,are also subject to flooding. The most serious flood hazard that exists in Contra Costa County relates to the system of levees that protect the islands and adjacent mainland in the San Joaquin-Sacramento River Delta area in eastern Contra Costa. Levees are basically long,continuous dams that keep water out of a lower area,such as the Delta islands,many of which are at an elevation just above or below sea level. The islands in the California Delta were drained during the nineteenth century to create high quality agricultural land. Since then,the peat-laden soil of many of the islands has oxidized,resulting in a sinking of their island floors and consequently requiring the construction of higher and heavier levees. Levee failure occurs in some areas where levees rest on soft mud,silt,or peat. The islands continue to flood. In general,the islands have been reclaimed after each flood. However,Franks Tract State Park, essentially a lake east of Bethel Island, and the Big Break area of water north of Oakley,are visible reminders that it is not always practical or economical to reclaim flooded lands. Flooding problems in the Delta area have also been exacerbated by boat movement(primarily recreational)on the waterways which causes waves that accelerate the natural process of levee erosion. The threat of levee failure during periods of high water is constant. In the years 1973, 1980, 1982, 1983,and 1986, one or more Delta island levees failed or were overtopped,and some of these events were summer breaks that did not occur at times of high storm runoff. Some islands in the Delta have been flooded two or three times since 1980. The possibility that flooding will occur on the islands in the Delta is greatly increased by two ongoing,natural processes,which compound the dangers that periodic high tides or strong winter storms may breach a portion of the existing levee system. The two natural process whichimp act the integrity of the levee are rising sea levels,caused by the world-wide"greenhouse effect,"and"subsidence." The greenhouse effect is a phenomenon that is projected to cause a rise in sea level over the next century,thus creating potential flooding problems. Hydrologists estimate the rate of rise may increase from the present one-half foot per century to approximately two to eight feet. The anticipated rise is believed to be caused by warming of the global climate due to accumulation in the atmosphere of gases such as carbon dioxide,methane,and chlorofluorocarbons which result fiun fossil fuel burning and deforestation of tropical rain forests. Since many factors affect global climates,the rate of change over a relatively short time-period,even a century,is very difficult to establish. The T.J.S.Envhumaerital Protection Agency suggests that a rate of four feet per century be assumed for planning purposes for the San Francisco Bay Area. It is important to note that the existing FEMA flood hazard maps do not include the greenhouse effect in their potential flooding analysis. In Contra Costa County,subsidence is caused by the natural process of oxidation of island peat soils,resulting in a gradual sinking of the ground. As many of the islands in the Delta(along with their levees)sink in elevation,the levees that protect the island's agricultural and/or residential uses must be raised and reinforced by adding more earth fill to the top of the levees. Recent evidence indicates that many islands have experienced significant subsidence over the last several decades. For example,it is estimated that Webb Tract in Contra Costa County has subsided up to 17 feet,and Bacon Island adjacent to Contra Costa County has subsided approximately 14 feet. Most reclaimed portions of the Delta in the County have subsided at least 10 feet. Areas that have experienced a measurable amount of subsidence are illustrated in Figure 10-8,Flood Hazards Map included in a later section of this chapter. These areas are highly susceptible to flooding. A number of causes for subsidence have been identified. The oxidation-decay and shrinkage ofpeat and other soils which are rich in organic matter and fine clay particles may be the largest contributor to the problem. However,the withdrawal of shallow ground water for surface drainage may also cause surface compaction and/or soil shrinkage, which results in a loss of elevation. There is also evidence that the pumping of groundwater,oil,or gas supplies from underneath several of the islands may be contributing to the natural consolidation and subsidence. Natural "tectonic"subsidence may also be contributing to the problem. There are great difficulties involved in estimating the amounts and rates of subsidence from island to island in the Delta, since subsidence changes the elevation of bench marks, the survey points from which elevations are determined. It is first necessary to establish elevation control from stable areas outside the Delta,which requires very long survey lines. Recent work is concentrating on the use of an unmanned space satellite as a "survey platform"from which to study changes in elevations. The consequence of subsidence and the possibility of sea levels rising due to the greenhouse effect is the increased potential that levees will fail and tidewater and high river water will inundate farmed and populated areas in the 10-23 10.Safety Element Delta. The California Delta in Contra Costa and in the adjoining counties has historically been devoted to agriculture and its population has remained small. However,growing commercial recreation and residential uses, as evidenced by the success of year-round subdivisions such as Discovery Bay, are leading to increases in the permanent population of the area. It will become increasingly more important,but also more difficult, for the --T County to provide adequate flood protection to residents and businesses in the Delta area. New urban development should be allow only if long term,year-round flood protection can be provided to the area. Allowing more residential and commercial development on or near the islands of the Delta increases the disaster potential of subsidence and flooding when levees fail. Approving land uses in the Delta area that support significant new populations must be carefully measured in terms of the potential loss of lives and property that could occur in the event of a major flood. The economic consequences of certain development should also be studied. -- Seismicity presents additional special problems in the Delta. Delta levees are,in places,underlain by sands that are susceptible to ground failures including liquefaction during an earthquake. Strong earthquake shaking can cause the entire levee foundation to lose strength,leading to levee failure. Many levees are themselves constructed of liquefiable sand. According to a report prepared for the East Bay Municipal Utility District,whose aqueduct pipes cross the Delta, twelve separate faults are capable of causing ground motion sufficient to cause liquefaction,requiring accelerations on the order of 7 to 27 percent of gravity(0.07 to 0.27g),with shaking lasting from about 5 to 23 seconds. A 1985 study by a State Department of Water Resources geologist noted levee slips and cracks from five recent earthquakes,some as distant as 150 miles away from Contra Costa County. A large nearby earthquake could cause a number of simultaneous levee failures,making repairs difficult because the levees are the only land access to -- many points following a levee break. In addition to the flooding hazards associated with levee failure caused by an earthquake,fault ruptures or ground shaking during an earthquake can cause the collapse of dams,as well as seiche and tsunami("tidal waves"). -- Dam safety is regulated by the State Department of Water Resources,Division of Safety of Dams. All large reservoirs in the County have been investigated and many have been strengthened. Further,the Office of Emergency Services has produced inundation maps and emergency plans covering various scenarios of dam failure in the County. The safety of small dams,which are mostly used for stock watering and other agricultural activities,is largely a private concern,with present standards set by the County Grading Ordinance. Many small dams predate even this regulation. However,seismic activity is not considered a significant hazard to small dams. Tsunamis are sea waves created by undersea fault movement. Traveling through the deep ocean,a tsunami wave is a broad,shallow,and fast moving wave. When it reaches the coastline,the wave form pushes upward from the ocean bottom and becomes a high swell of water that breaks and washes inland with great force. The waves may reach fifty feet in height on unprotected coasts,and one recorded tsunami(in Japan in 1896)killed nearly 30,000 people and destroyed over 10,000 homes. Several people were drowned in Crescent City,California,in 1964 by the tsunami generated by the"Good Friday"Alaska earthquake. Historic records of the Bay Area used by one study indicate that 19 tsunamis were recorded in San Francisco Bay during the period of 1868-1968. The maximum wave height recorded at the Golden Gate Tide Gage was 7.4 feet, which may be regarded as a reasonable maximum for future events. The available data indicate a systematic diminishment of wave height from the Golden Gate to about half that height on the shoreline near Richmond,and to nil at the head of the Carquinez Strait. Thus,the damage potential of a tsunami will tend to be greater in the Richmond area and show a general decrease toward the head of Carquinez Strait. Flooding can also result from seiche,which is a long wave-length,large-scale wave action set up in a closed body of water such as a lake or reservoir. Seiche is known to occur during earthquakes,but is not well understood. No occurrences have .... been recorded in the Bay Area. Elongated and deep(relative to width)bodies of water seem most likely to be affected,and earthquake wave orientation may also play a role in seiche formation. Seiche can temporarily flood a shoreline in a manner similar to tsunami;however,its destructive capacity is not as great. Seiche may cause overtopping of impoundments such as dams,particularly when the impoundment is in a near-filled condition,releasing flow downstream. Maps of Flood Hazard Areas Figure 10-8 depicts the general location of the FEMA flood hazard areas throughout Contra Costa County. Flood Hazard Areas are those areas which have statistical chance of flooding once in 100 years. This map is not intended to be used to 10-24 ,ow 10.Safety Element locate parcel-specific sites in relation to Flood Hazard Areas,but to convey the general extent and location of'such areas. The map also indicates areas of subsidence in the County,but does not presently include consideration of the greenhouse effect. FLOOD HAZARD GOALS 10-G.

Land uses involving hazardous materials or other hazards considered in this section include airports, the Concord Naval Weapons Station, petroleum and chemical processing plants, oil and gas wells, and petroleum product and natural gas pipelines. In addition,land uses that involve hazards to navigation are considered here. Heavy industrial land uses centered on the west and north shores of the County have the potential to present significant Amaw risk to public safety because of the hazardous nature of some petroleum and chemical materials. Potential hazards include explosion and flammability of petroleum products and other chemicals,and chemical toxicity. Hazardous materials uses are concentrated in heavy industries along the coasts,and are also present in lesser quantities in industrial parks in the Counts interior. Notwithstanding industrial safety procedures,the presence of large quantities ofhazardous materials in the County,particularly close to and/or upwind of populated areas,poses a potential safety hazard at all times. Many industrial uses in the County are located on reclaimed marshland underlain by soft, wet, unstable mud. However,damage from earth movements are believed to have a low probability of occurrence because of adequate foundation design of buildings and other structures. Information is not available on whether or not there are older tanks used to store hazardous materials that are not .--� sufficiently stabilized. Informal observation of tanks in the County indicates that there is no requirement to space tanks far enough apart to prevent a fire or explosion from spreading. In areas in which tanks are closely spaced, particularly where these are close to population centers,there is a potential for a disaster affecting a significant population. Although historic accident records suggest that such a risk is low,the seriousness of the event,should it occur,indicates that some additional measure of public safety may be advisable. Hundreds of miles of pipelines for the transportation of natural gas, crude oil, and refined petroleum products traverse Contra Costa County,including residential and commercial areas. Such pipelines cross areas with active fault lines, landslide deposits,unstable slopes, and areas underlain by soft mud and peat. The risk presented to pipelines by geologic conditions has not been quantified. The public safety hazard from a pipeline break would Maedepend on the proximity of the accident to populated areas as well as the nature of the event that produced it(e.g., the landslide or earthquake). 10-28 1 I1 M1 (4 rf Q 3 9 dft z� tires ��q Q • • U mLL.c+ w Apply IAL dh irL rl r ; a ira �G 4 l � a ,....�- r� V1 i � t ti V � t � ti 0 rn � CV it C t at t o Page bJ ,, 10-30 10.Safety Element In general, natural gas is believed to be less hazardous to the public than petroleum products because it is transported at lower pressures and,when released,rises and dissipates into the atmosphere. Petroleum products are pumped at pressures up to 200 pounds per square inch and,when released,flow along the ground. Petroleum fires are also more likely to spread to nearby property than vertical-burning natural gas fires. Several h ndfedN-umerous active gas and oil wells are located in the County,most of which are far from populated areas. Although there is a risk of a well catching on fire,such incidents have been very few and the risk of such a fire causing a general disaster is remote. North and east of Brentwood,future parcel splits resulting in a dispersed but sizeable population could lead to a public safety hazard if rural residential areas are permitted to encroach on the gas producing area. Further,a concentrated population in proximity to the numerous wells in peat areas could expose persons and properties to peat fires which are difficult to control and may smoulder for weeks or months before they are completely extinguished. No particular routes for hazardous materials transportation are designated in the County. Most of these materials are regularly carried on the freeways and major roads designated as explosives routes. The proximity of some of these routes to large numbers of people suggests that an accident involving hazardous materials transportation could reach disaster proportions. The extreme toxicity of some chemicals used in the County and the specialized handling and cleanup procedures required during an accident make proper information and training of local response agencies,such as the police and fire departments,essential. A unique risk to public safety is presented by transportation in the County of quantities of various radioactive materials. In the event of an accident, small amounts of radioactive materials can be dislodged from their protective containers and become extremely difficult to locate. Emergency response to a spill involving radioactive materials requires special knowledge and equipment,and persons may be unknowingly subjected to radiation in traffic accidents or other routine mishaps. Explosives are defined in the California Health and Safety Code(S 2565 Has any substance or combination of substances the primary purpose of which is detonation or rapid combustion. Most munitions and some chemical materials are included in the Class A explosives category regulated by the State and various bridge authorities. There are numerous users of explosive materials in the County, but by far the largest is the C-e AQ;RA —balUCAU fis statinaAnny s Military- Traff c Management Command, to and from which munitions are regularly transported by truck,train and ship. Other explosives used for construction and quarrying are present in smaller amounts throughout the County. Two major railroad companies serve Contra Costa County--=Burlington Northern--Santa Fe and South Union Pacific --and both transport munitions for CN W the.Anny's Military Traffic Management Command. Truck transportation of explosives through populated areas constitutes a potential significant public safety hazard. Permitted routes designated by the California Highway Patrol include the major freeways and other highways in the County. While training requirements exist for carriers of hazardous materials,including explosives,they may be unable to perform immediate remediation of emergency conditions under some situations. The County is responsible for determining land uses and community development configuration within its jurisdiction,but does not determine the nature of substances used on industrial and military sites. Nor does the County grant permits for the use or transportation of hazardous materials, determine appropriate routes for transporting these materials,or require properly informed emergency personnel. Public safety in regard to the use and transportation of hazardous substances generally depends on actions by the State and federal governments. In the case of land uses involving hazardous materials,the County Planning Agency can minimize public safety risks by ensuring that hazardous materials use areas and residential populations are separated to the extent that fire or explosions on industrial and military properties or in gas and oil well areas will not spread to homes or businesses. Preventing environmental releases of hazardous materials depends primarily on industrial safety requirements and procedures. By requiring that project proposals to construct tanks, pipelines, and other facilities be accompanied by thorough investigations of the natural and manmade hazards potentially affecting the proper functioning of these facilities,the County can be assured that risks are reduced to the minimum level that can be achieved by engineering technology. Since emergency and disaster plans and procedures have been prepared by the County Office of Emergency Services (OES), it is appropriate for all potentially disastrous events to be reported to this ^ffi^ethem, so that County emergency services such as traffic control,fire and medical equipment,and evacuation notification can be 10-31 ...... 10.Safety Element available if needed.-R-4,sex-peeted!hat eniefgeney!:JAX:13;341 related te aif:tfaffie eengestion at the Bueltatia A-WA VW Ad A ,,%wA'%A%AAA L TV AAA kO'%w k1oll A.A.kY&A%A%0 16 VO A A%.7 4 Contra Costa County is home to numerous businesses and industries that manufacture, store,use and dispose of "INft hazardous materials and hazardous waste. These businesses are neighbors to an increasingly urbanized population. To ensure the protection of public health and safety and the environment,it is imperative to plan for the safe and effective use of hazardous materials and the management of hazardous waste. In recent years, there has been a growing understanding of the widespread use of hazardous materials. Contra Costa County began planning specifically for the management of hazardous materials and waste in 1983, with the establishment of the County Hazardous Waste Task Force. Most The County has completed the County Hazardous Waste Management Plan, a comprehensive analysis of all aspects of hazardous waste ^moo management from generation through disposal. The plan establishes goals and policies for the safe management of hazardous waste,and recommends the establishment of programs designed to reduce hazardous waste generation by 30 to 40 percent by the year 2000. The plan,which serves as the primary planning document for hazardous waste management in the County and in the incorporated cities,projects the need for commercial hazardous waste management facilities and specifies criteria to determine whether a facility may be established. The management of hazardous materials is the focus of the Contra Costa County Hazardous Materials Area Plan,which was MOM adopted in January of 1988. This Plan outlines the procedures that County regulatory and response agencies will use for monitoring containing and removing hazardous materials from the site of an actual or duratened accidental release. The plan also identifies the agencies within the County responsible for the effective of hazardous materials. --hm" Navir.ational Hazards With over 70 square miles of water and hundreds of miles of shoreline along the bays,rivers and sloughs,off-shore waters are particularly important in Contra Costa County for industrial,commercial,agricultural and recreational uses. The public right to use open water for navigation is established in the State constitution and State law,but navigation can be hazardous if land-based activities result in obstructions,such as docks,low bridges,or elevated pipelines. Where waters are shallow for some distance from shore commercial and industrial docks are usually built out to the shipping channel as a more acceptable plan than continuously dredging a side channel closer to shore. The Corps of Engineers permit system prevents docks from encroaching into shipping channels. Small docks for commercial or private recreational use have proliferated around Bethel Island and on the mainland side of Sand Mound Slough. The U.S. Department of the Interior,,noting"a plethora of uses not associated with commerce activities"on the State's waterways indicates that controls are necessary to protect the public right to use navigable waters. It should also be recognized that because thousands of boaters use the Delta annually,many of them not skilled,the proliferation of smaller docks may be a hazard to public safety. The risk would not be of a disastrous single event, but is rather a persistent hazard probably affecting only a few persons at a time. As previously mentioned,additional discussion of the County HWMP and related General Plan goals and policies is provided in the Public Facilities/Services Element of this document. For a listing of General Plan goals regarding hazardous waste management,the reader is directed to Section 7.12. HAZARDOUS MATERIALS GOALS 104.

Applications for private or commercial recreation docks which would encroach into waterways used primarily for recreation boating should be reviewed by the County to evaluate their aggregate impact upon public safety. HAZARDOUS MATERIALS IMPLEMENTATION MEASURES 10-ad. Encourage the State Department of Health Services and the California Highway Patrol to review permits for radioactive materials on a regular basis and to promulgate and enforce public safety standards for the use of these materials,including the placarding of transport vehicles. 10-ae. Request that State and federal agencies with responsibilities for regulating the transportation of hazardous materials review regulations and procedures, in cooperation with the County, to determine means of mitigating the public safety hazard in urbanized areas. 10.10 WATER SUPPLY REQUIREMENTS INTRODUCTION This section of the Safety Element focuses on water supply safety issues. For a discussion of issues related to general domestic water supply,the reader is directed to the Public Facilities and Services Element of this general plan. Water supply requirements increase during a disaster,with extra amounts being used for fire fighting,sanitation, and debris clean up. Damages to this essential supply can occur in the centralized parts of water supply systems-- the intakes,canals,and major reservoirs--or at the delivery points as a result of disruption of main lines or of the many subsidiary lines to each home,school,business,or hospital. Damage to centralized parts of the water supply system has the potential to affect thousands of persons but can be repaired relatively quickly. Loss of water in localized areas would affect fewer people,but because repair times could be long,hazards to property and safety could be greater for inhabitants of such areas. In a general or widespread disaster the water supply to several parts of the County could be disrupted for days or weeks. Although the risk of such an event is believed to be low,the seriousness of the impact on affected communities indicates that citizens, water suppliers and government agencies should be prepared to supplement water supplies for disaster recovery uses. Large low-density areas of the County do not use water from large public systems,but instead rely on wells. These areas would be expected to have less difficulty supplying water in the event of a disaster such as an earthquake. WATER SUPPLY GOALS 10-J.

The Contra Costa County Office of Emergency Services prepares disaster plans for the county and coordinates required emergency services and facilities from all agencies and levels of government to meet emergency and disaster needs. While there is some overlap between this element and the Public Facilities and Services Element,the policies contained here are primarily related to disaster situations,rather than to ongoing facilities and services standards. Aside from the emergency/disaster situations previously described in this element such as earthquakes,floods and accidental releases of hazardous materials,the Safety Element addresses the additional areas of wildfire,emergency medical response and crime prevention. Wildfire Fire hazards present a considerable problem to vegetation and wildlife habitats throughout the County. Grassland fires are easily ignited,particularly in dry seasons. These fires are relatively easily controlled if they can be reached by fire equipment; the burned slopes, however,are highly subject to erosion and gullying. While brushlands are naturally adapted to frequent light fires,fire protection in recent decades has resulted in heavy fuel accumulation on the ground. Brush fires,particularly near the end of the dry season,tend to burn fast and very hot,threatening homes in the area and leading to serious destruction of vegetative cover. While woodland fires are relatively cool under natural conditions, a brush fire which spreads to a woodland could generate a destructive hot crown fire. No suitable management technique of moderate cost has been devised to reduce the risk of brush fires. Because the natural vegetation and dry-farmed grain areas of the County are extremely flammable during the late summer and fall,wildfire is a serious hazard in undeveloped areas and on large lot homesites with extensive areas of unirrigated vegetation. Several factors affect the relative degree of wildfire hazard, including atmospheric humidity,slope steepness,vegetation type,exposure to the sun,wind speed and direction,accessibility to human activities and accessibility to firefighting equipment. Taking these factors into consideration,a fire hazard severity scale has been devised which characterizes areas throughout the County by the number of days of moderate,high and extreme fire hazard. Mapped information on fire hazard severity is included later in this section. Peat fires represent a special hazard in that once ignited,they are extremely difficult to extinguish. In some instances, islands have been flooded in order to extinguish peat fires. Any area lying generally east of the mean high water line may be peaty due to the marshy origin of the soil,although local areas of mineral soil are present within the general area. Emereency Medical Response Medical emergency services are provided by hospitals,ambulance companies and fire districts. Considerable thought and planning have gone into efforts to improve responses to day-today emergencies and planning for a general disaster response capability. However,certain areas remain which require improvement to enhance public safety. Identification of streets,house numbers,and townhouse and apartment units remains a major factor hampering locating patients. Design of multi-story buildings rarely includes provision for elevators or stairways which can accommodate gurneys,which are preferred for patient transport because they allow for continuous care. In the event of a disaster,many persons could be affected. Although substantial progress has been made in terms of earthquake restrainers being added to freeway overpasses, cities and communities with limited access to hospitals,such as Lafayette,Moraga and Orinda,are still at some risk to access blockage due to the potential for landslides or traffic accidents to temporarily close roads. Crime Prevention While it is not a purpose of this element to deal with crime as such,there are planning-related opportunities to aid in the efficiency of police services and incorporate crime reducing features into development projects which could enhance public safety at relatively little public cost. Response times can be hampered by uncoordinated street naming between jurisdictions,or by conflicting street numbering between cities and the County on the same road/street name. 10-35 10.Safety Element Defensible space is a concept which incorporates crime prevention principles into development design. This "", concept has already been discussed in the"Public Protection"section of the Public Facilities/Services Element. Maps In general, the fire hazard severity is related to distance from the marine atmospheric influences of the Pacific Ocean,intervening topography,slope steepness and vegetative type and coverage. Figure 10-10 shows these areas. PUBLIC PROTECTION SERVICES AND DISASTER PLANNING GOALS 10-N. To provide for a continuing high level of public protection services and coordination of services in a disaster. PUBLIC PROTECTION SERVICES AND DISASTER PLANNING POLICIES 44A.1.0-83. The Office of Emergency Services,in cooperation with cities within the County,shall delineate evacuation routes and,where possible,alternate routes around points of congestion. X0-85:10-84. The Office of Emergency Services,in cooperation with public protection agencies,shall delineate emergency vehicle routes for disaster response,and where possible,alternate routes where congestion or road failure could occur. 40-86~:10-85. In order to ensure prompt public protection services,dwelling unit numbers shall be required to be easily seen from the street or road. .10-86. In order to reduce the risk of crime at little public cost,the County shall encourage the use of citizen action programs such as Neighborhood Alert and Operation ID. 10-88.10-87. The County shall require adequate access for medical emergency equipment in high-occupancy buildings of over two stories. 10-8 :10-88. Every high-rise building shall be designed and constructed to provide for the evacuation of occupants and/or for the creation of a safe environment in case of a substantial disaster,such as a severe earthquake or fire. �... X0 90.10-89. Policies related to wild land fire risk are contained in the Fire Services section of the Public Facilities Element 10 94-.10-90. Restrict homes built in rural areas or adjacent to major open space areas from having roofs which are covered with combustible materials. Figure 10-10 contains the characterization of fire hazard for the County by Fire Weather Classes,and delineates those areas of the County which are subject to peat fires. ,aloft The Fire Weather Classes depicted on Figure 10-10 are defined in terms of the number of days per year of Critical Fire Weather. Class 1 has 0 to 1 days per year of Critical Fire Weather,Class II has 1 to 9.5 days and class III has over 9.5 days. PUBLIC PROTECTION SERVICES AND DISASTER PLANNING EMPLEMENTATION MEASURES 10-ap. Undertake a program in cooperation with cities within the County to unify street name and numbering systems. 10-aq. In cooperation with cities within the County and public protection agencies,delineate evacuation routes, emergency vehicle routes for disaster response and,where possible,alternative routes where congestion or road failure could occur. 10-ar. Development of areas identified by the criteria of the State Division of Forestry as having an Extreme Fire Hazard will be avoided where possible. Homes located in extreme or high fire hazard areas will be constructed with fire-resistant materials and the surroundings should be irrigated or landscaped with fire resistant plants. mom 10-as. Require projects which encroach into areas which are determined to have a high or extreme fire hazard,or which incorporate wildfire hazard areas,to be reviewed by the appropriate Fire Bureau to determine if special fire prevention measures are advisable. ... 10-at. Major developments will not be approved if fire fighting services are not available or are not adequate for the area. 10-36 .� E V ' N / a..:ty r4rrY.:i.�'.,�lw�r•.t•r�q �„ • 0vw:x / I �.ar. � RY4t'�yF'y`,w,.•{:(}Ycir1v�'ii ;:t_.4i��♦ `� ii I. rv:rS�.'O•+• � x 4�y y'•..:✓4,V,t MSaAn ,•• '.Vii: a � ;�trt�:?,i:x ��^trlrxr••rii+"ka ak•���x %if• A �., h M F I `.:$;r�{a.•sa'' 'aY 'Y�'a`ixavr"i+•y.wra+:.ZraY`u'x•a •�r°Y a, ,�'.

NOISE ELEMENT 11.1 INTRODUCTION Section 65302(f)of the California Government Code requires that a noise element be prepared as a part of all city and county general plans. This State law requires that a jurisdiction's noise element identify and work toward mitigation of noise problems in the community. This Noise Element analyzes and quantifies, to the extent practical as determined by the legislative body,current and projected noise levels for all of the following sources: o Highways and freeways; o Primary arterials and major local streets; o Passenger and freight on-line railroad operations and ground rapid transit systems; o Commercial and general aviation,heliport,helistop, and military airport operations; aircraft flyovers,jet engine test stands,and all other ground facilities and maintenance functions related to airport operation; o Local industrial plants including,but not limited to,railroad classification(switching)yards;and o Other ground stationary noise sources identified by local agencies as contributing to the community noise environment. Noise contours are shown for many of these sources and stated in terms of the day/night average sound level (DNL or Ld.). The noise contours are to be used to guide land uses,as specified in the Land Use Element,so that the exposure of community residences to excessive noise is minimized. According to the Code,noise elements shall also include implementation measures and possible solutions that address any existing and perceivable noise problems. The adopted Noise Element shall serve as a guideline for compliance with the State Noise Insulation Standards. (Title 24,Part H,CCR.) This Noise Element follows the guidelines established by the California Department of Health Services entitled, "Guidelines for the Preparation and Content of the Noise Element of the General Plan." The State Guidelines define noise metrics, discuss the process of Noise Element development, and present land use compatibility guidelines based on various noise levels. The contents of the State's guidelines document were reviewed in preparation of this Element and the relevant portions are incorporated into this document. 11.2 RELATIONSHIP TO OTHER GENERAL PLAN ELEMENTS The General Plan elements are important tools used by elected officials to provide policy guidance and assist in decision making. All of the elements of the General Plan are related and interdependent to some degree. However,the Noise Element is most closely related to the Land Use,Housing,Circulation,and Open Space Elements,as shown in Table 11-1. 11.Noise Element TABLE 11-1 RELATIONSHIP OF NOISE ELEMENT TO OTHER GENERAL PLAN ELEMENTS low"" LAND USE HOUSING Guidelines for accepting land uses Decisions regard design,location and in relation to existing and attenuation measures for noise projected noise contours. sensitive areas. NOISE CIRCULATION OPEN SPACE Location,capacity,and design Through separation and extensive determines the extent of noise landscaping noise can be mitigated. impact. The major objective of a noise element is to provide guidelines to achieve noise land use compatibility. The Land Use and Noise Elements,therefore,are related closely. By identifying noise-sensitive land uses and establishing compatibility guidelines for land use and noise,the Noise Element will influence the general distribution,location, and intensity of future land use. Effective land use planning can alleviate noise problems. Residential areas are one of the noise-sensitive land uses. Therefore,the Housing Element is directly affected by the Noise Element. The Housing Element policies and programs should include safeguards against noise intrusion. The implementation of Land Use/Noise Compatibility Guidelines can reduce noise impacts in residential locations. In addition,proper noise mitigation measures during housing construction can guard against adverse noise impact. A city's circulation system is one of the major sources of continuous noise. Therefore, the existing and future circulation system identified in the Circulation Element will influence greatly the Noise Element. Circulation routes such as freeways,highways, and truck routes should be located to minimize the noise impact on noise- sensitive land uses. The location and design of transportation facilities and possible mitigation of noise from #Now existing and planned facilities will greatly influence the overall noise environment within the City. Since noise can affect adversely the enjoyment of quiet activities in open space,the Noise Element is also related closely to the Open Space Element. Inversely, open space can be used as a noise buffer between incompatible land uses. This technique can reduce community noise levels and also provide usable open space for recreation. The goals,policies and implementation measures contained in this Element are intended to guide planning for OWNS public and private projects that are subject either to approval of the County Planning Agency or to review by County staff,although they may be under the jurisdiction of other public agencies operating in the County. Such goals,policies and implementation measures are further intended to be in accordance with the other elements of the 001- General Plan, as well as with other planning documents. This Element completely supersedes the 1975 Noise Element. am" 11-2 -- 11.Noise Element 11.3 ACOUSTICAL STANDARDS Many governmental agencies have promulgated noise standards for various types of projects. In general,these standards are intended to protect persons from excessive exterior and interior noise. Most of these standards address vehicular traffic noise while others address rail,aircraft,or fixed sources. The Department of Housing and Urban Development(HUD)has developed noise policies for Federal housing projects. These HUD policies are contained in'The Noise Guidebook. The policies contained in the guidebook discuss various outdoor noise environments and recommend acceptable interior and exterior noise level goals. The State of California has adopted Title 21 and Title 24,Part 2,of the California Code of Regulations. Title 21 limits airport noise near residential communities to minimize e existing and future land use conflicts. Title 24,Part 2,is concerned with transportation and industrial noise sources and specifically regulates the maximum allowable interior noise level for hotels,motels,and multi-family housing. Title 24,Part 2,also establishes standards for sound isolation of party walls,corridor walls,and floor/ceiling assemblies in multi-family residential construction. The Federal Highway Administration(FHWA)and California Department of Transportation(Caltrans)have similar policies for new roadway construction and roadway expansion. These policies contain maximum acceptable noise levels in areas adjacent to vehicular traffic. These policies also have guidelines for determining when noise barriers should be constructed. The Countys and Use Commission(ALUC)oversees development near airports. The ALUC has a plan Airport L which contains goals and policies. These policies are considered when a project is proposed near an airport or heliport in the County. In addition to a noise element,counties and cities can also adopt noise ordinances. A noise ordinance is intended to regulate sources such as amplified music,construction and mechanical equipment. 11.4 NOISE ELEMENT ORGANIZATION The Noise Element is divided into six remaining sections. These sections dcfme noise probkrns-,quantify the noise probkrns-, set up goals and policies;and,finally,provide implementation mm%=to or eliminate the noise problem. 11.5 FUNDAMENTAL CONCEPTS OF ENVIRONMENTAL NOISE BACKGROUND Three aspects of community noise are important in determining subjective response: 0 The level of the sound(i.e.,magnitude or loudness); 0 The frequency composition or spectrum of the sound;and 0 The variation in sound level with time. Airborne sound is a rapid fluctuation of air pressure and local air velocity. Sound levels are measured and expressed in decibels(dB)with 0 dB roughly equal to the threshold of hearing. The frequency of a sound is a measure of the pressure fluctuations per second,measured in Hertz(Hz). Most sounds do not consist of a single frequency,but are comprised of a broad band of frequencies differing in level. The characterization of sound level magnitude with respect to frequency is the sound spectrum. A sound spectrum is often described in octave bands that divide the audible human frequency range(i.e.,from 20 to 20,000 Hz)into ten segments. Figure 11-1 shows a range of sound spectra for various types of sound over the audible hearing range. FREQUENCY WEIGHTING Many rating methods exist to analyze sound of different spectra. Generally,the simplest method is used so that measurements may be made and noise impacts readily assessed using basic acoustical instrumentation. This method evaluates all frequencies by using a single weighting filter that progressively de-emphasizes frequency components below 1000 Hz and above 5000 Hz. This frequency weighting,shown in Figure 11-2,reflects the relative decreased sensitivity of humans to both low and extremely high frequencies. This weighting is called A- weighting and is applied by an electrical filter in all U.S.and international standard sound level meters. Some typical A-weighted sound levels are presented in Figure 11-3. 11-3 r. s• �r N �,("� sN•Nss� N • • • • • i ! • • a • M V�A i C i i � VOOA ! 0 R f ir 0 lop u POW POOO C4 top o 'Page twoa 1 ' qw �; to IlillilliilllllllllllIIIIIIIIIIIIIIIIIIIIIIillillilillilljlllllll11111111ilillillillill'00000000000 Q Figure 11-3 Typical Sound Levels Measured in the Environment and Industry A—WEIGHTED SOUND PRESSURE LEVEL, IN DECIBELS 140 130 THRESHOLD OF PAIN CIVIL DEFENSE SIREN (100') JET TAKEOFF (200') 120 RIVETING MACHINE 110 ROCK MUSIC BAND DIESEL BUS (15') 100 PILEDRIVER (50') -- AMBULANCE SIREN (700') BAY AREA RAPID TRANSIT 90 BOILER ROOM TRAIN PASSBY (10') PRINTING PRESS PLANT PNEUMATIC DRILL (50') soGARBAGE DISPOSAL IN THE HOME SF MUNI LIGHT—RAIL VEHICLE (350) INSIDE�� SPORTS CAR, 50 MPH FREIGHT CARS (100') VACUUM CLEANER (10') so DATA PROCESSING CENTER SPEECH (1') DEPARTMENT STORE AUTO TRAFFIC NEAR FREEWAY so PRIVATE BUSINESS OFFICE LARGE TRANSFORMER (200') SIGHT TRAFFIC (100') AVERAGE RESIDENCE 40 TYPICAL MINIMUM NIGHTTIME � LEVELS--RESIDENTIAL AREAS SOFT WHISPER (5') 20 RUSTLING LEAVES RECORDING STUDIO r�10 THRESHOLD OF HEARING MOSQUITO (3') 0 (100') = DISTANCE IN FEET BETWEEN SOURCE AND LISTENER CONTRA COSTA COUNTY �. page 631 Pine ,,�..,,.�u.�,,,..d „gym„ 11-5 3, 1.Noise Element NOISE EXPOSURE WNW Noise exposure is a measure of noise over a period of time,whereas the noise level is at an instant in time. Although a single sound level may describe adequately community noise at any moment,community noise levels vary continuously. Most community noise is produced by many distant noise sources that produce a relatively steady background noise having no identifiable source. These distant sources change gradually throughout the day and include traffic,wind in trees,and distant industrial activities. Superimposed on this slowly varying background is a succession of identifiable noise events of brief duration. These include nearby activities,such as single vehicle passbys or aircraft flyovers. AAMM A single number called the equivalent sound level(IQ is used to describe the average noise level over a period of time (i.e.,the total sound energy divided by the duration). Thus,the Lqis the constant sound level that would contain the WAMW same acoustic energy as the varying sound level,during the same time period. In determining the daily measure of community noise,it is important to account for the difference in human response to daytime and nighttime noise. Nighttime exterior background and household noise levels are generally lower than in the daytime. People are more sensitive to noise at night than during other periods of the day and exterior noise intrusions become more noticeable. To account for human sensitivity to nighttime noise, the DNL (Ldn) descriptor was adopted by the Environmental Protection Agency to describe community noise exposure from all sources. The DNL is called the day-night sound level and represents the 24-hour A-weighted equivalent sound level with a 10-dB penalty added to the"nighttime"hourly noise levels(HNL)between 10:00 PM to 7:00 AM. DNL and CNEL levels are typically computed by energy summation of HNL values,with the proper adjustment applied for the period of evening or night. The CNEL is computed identically to the DNL but with the addition of a 5-dB penalty to the evening HNL(i.e., 7:00 PM to 10:00 PM). The CNEL value is typically less than I dB above the DNL value. Figure 11-4 shows the adjustments applied for the DNL and CNEL measures. Noise exposure measures such as Lq,HNL,DNL,and CNEL are all A-weighted,with units expressed in decibels. SUBJECTIVE RESPONSE TO NOISE The effects of noise on people can be classified into three general categories: 0 Subjective effects of annoyance,nuisance,dissatisfaction; 0 Interference with activities such as speech,sleep,and learning; and 0 Physiological effects such as anxiety or hearing loss. The sound levels associated with community noise usually produce effects only in the first two categories. No universal measure for the subjective effects of noise has been developed, nor does a measure exist for the -- corresponding human reactions from noise annoyance. This is primarily due to the wide variation in individual attitudes regarding the noise source(s). An important factor in assessing a permfs subjective reaction is to compare the new noise environment to the existing noise environment In genaraL the more a new noise level exceeds the prior existing level,the less acceptable it is. i Therefore,a new noise source will bejudged more annoying n a quiet area than it would be in a noisier location. Knowledge of the following relationships is helpful in understanding how changes in noise and noise exposure are perceived.: 0 Except under special conditions,a change in sound level of I dB cannot be perceived; Maw 0 Outside of the laboratory,a 3 dB change is considered a just-noticeable difference; 0 A change in level of at least 5 dB is required before any noticeable change in community response maw would be expected; and 0 A 10 dB change is subjectively heard as an approximate doubling in loudness and almost always causes an adverse community response.

The frequency scale is also measured in logarithmic increments. Decibels,measuring ._., sound energy,combine logarithmically. A doubling of sound energy(for instance,from two identical automobiles passing simultaneously)creates a 3-dB increase(i.e.,the resultant sound level is the sound level from a single passing automobile plus 3 dB). The rules for decibel addition used in community noise prediction are: o If two sound levels are within 1 dB of each other,their sum is the highest value plus 3 dB; o If two sound levels are within 2 to 4 dB of each other,their sum is the highest value plus 2 dB; o If two sound levels are within 5 to 9 dB of each other,their sum is the highest value plus 1 dB; and o If two sound levels are greater than 9 dB apart,the contribution of the lower value is negligible and the _... sum is simply the higher value. 11.6 NOISE IN CONTRA COSTA COUNTY OVERVIEW In Contra Costa County,traffic along freeways(e.g.,Interstate 80,Interstate 680,State Rouge 24,and State Route 4),and major arterials(e.g.,Willow Pass Road and Ygnacio Valley Road)are the primary sources of vehicular traffic noise. Rail operations also contribute to the noise environment in the County. The Atchison Topeka and Santa Fe (ATSF) and Southern Pacific (SP)railroad corridors in the County are primarily freight lines. These lines -- generate high noise levels during passbys and their trains are required to sound their whistles when crossing roadways at-grade. The Bay Area Rapid Transit (BART) system is an electrically driven passenger line. BART passbys are typically less noisy than the freight trains. BART trains do not have at-grade crossings. -- Existing air traffic activity also contributes to the noise in Contra Costa County. Buchanan Field, near Concord,is the primary source of aircraft noise. Other sources of aircraft noise are local emergency airports and military helicopter activity. The remaining noise sources are industrial plants such as oil refineries and materials processing plants. The Camp Parks Reserve Forces Training Area(RFTA)near San Ramon also is a noise source. Typical operations at Parks RFTA include small caliber weapons training,helicopter overflights,and vehicular activity. ONGOING PROBLEMS Boom There are many areas within the County that have existing noise problems. Buchanan Field is a constant source of noise complaints. According to the County, it generated• • . ' 375 complaints a min 2003. Interstate 80,680 and Route 4 also generate complaints. However,these complaints typically are handled by the California Department of Transportation. Rail switching yards in Martinez and Richmond are also noisy and have generated complaints. Quall Oil M .- • Industrial . noise generation continues to be a concern.

For example,residential land uses still will remain in relatively close proximity to some industrial noise sources. Currently, residential development is being built or proposed near Camp Parks RFTA. Although adequate setbacks and noise mitigation are usually incorporated into these projects,occasional complaints can be expected. Similarly,loud parties,outdoor music,and other industrial sources will continue to generate sporadic complaints. Activities at Buchanan Field are not anticipated to decrease in the future and may even increase. This activity would be expected to generate future complaints. Gas wells located in East County may be a source of future complaints. These wells generate a high-frequency hissing sound. In preparing this Noise Element,all the existing noise complaints and potential future ones were considered in the development of goals and policies. The purpose of these goals and policies is to protect future residents from the negative impact of noise and,if possible,minimize and reduce the number of complaints the County receives. 11-9 11.Noise Element 11.7 NOISE CONTOURS METHODOLOGY Existing and future traffic noise levels are based on calculations using the Federal Highway Administration Traffic Noise Prediction Model(FHWA RD-77-108),continuous 24-hour noise measurements,and short-term 15-minute measurements along freeways and major arterials in the County. The FHWA method predicts the average hourly noise level along a roadway based on the number of vehicles,the speed of the vehicles,and the percentage of medium and heavy trucks. The 24-hour average noise level(DNL)along a roadway,was calculated from the continuous 24-hour noise measurements. Along some roadways,however,only a 15-minute noise measurement was made. To calculate the DNL,the 15-minute measurement results were compared to the noise level measured during the same time period at a 24-hour noise measurement location on a nearby or similar roadway. The difference between the measured hourly noise levels and the DNL then was calculated for the 24-hour measurement location and the same offset was applied for the 15-minute measurement location. To determine the 24-hour noise level where no measurements were taken,the peak hour L,,q was calculated using the FHWA method and traffic volumes provided by the County The DNL was determined in a manner similar to that of the short-term measured roadways. By comparing the peak-hour noise level(L,,q) and the DNL from 24-hour noise measurements made in the vicinity of the roadway,a peak hour L.,,q to DNL offset was determined. low— This offset was applied to the calculated peak hour level to determine the DNL at the non-measured location. NOISE CONTOUR MAPS/TABLES Roadways/Rail Lines Existing and future DNL noise contours have been prepared for freeways,major arterials,and railways in the County. The contours were prepared on USGS quad maps. A reduced set of the future contours are provided in this document(see Figures 11-5A through 11-5U5Y). Table 11-3-2 summarizes the information contained in the future noise contours. A complete set of full size existing and future noise contours is available for public review at the Community Development Department offices. Airports/Heliports Existing and future CNEL noise contours are provided for Buchanan Field and Byron Airport. These contours were taken from ' AH-he Airport Land Use Compatability Plan adopted by the Contra Costa County Airport Land Use Commission in December of?000. USE OF MAPS/TABLES Noise contours are typically used for planning purposes in conjunction with new residential development. Since the actual full-size contour maps for roadways and rail lines are not contained in the Noise Element,Table 11-3-?has been pry. These tables and maps are designed to help planners,developers,and consultants identify a parcel or proposed residential project that is potentially impacted by noise. The table is intended to be used as follows: Step 1. Determine distance of the project site from a major noise source such as a roadway,airport,or rail.line. Step 2. If the noise source is a roadway or rail line:from Table 11-42,determine the distance from the rail line or roadway centerline to the future 60 DNL contour. soup If the noise source is an airport,determine if the project is within the 60 CNEL contour. Step 3. If the project is within the future 60 DNL or CNEL contour,an acoustical study should be initiated. MOM- Noise contours do not always account for the acoustical shielding provided by site geometry or terrain. Therefore,these contours may overestimate the noise exposure of a particular site. However,noise contours should only be used as a screening tool. Site-specific noise levels and other acoustical issues should be addressed in the acoustical study for the project. 11-10 " 11.Noise Element TABLE 11-32 FUTURE NOISE LEVELS ALONG FREEWAYS AND MAJOR ARTERIALS Distance to DNL at 100 ft. 60 DNL Contour Road/Segment (dB) (feet) Appian Way Route 80 to Valley View Road 65 270 Valley View Road to San Pablo Dam Road 66 320 Bethel Island Road Cypress Road to Gateway Road 67 370 Bollinger Canyon Road 70 620 Byron Highway(M) Cypress Road to Orwood Road 65 270 Orwood Road to Payne Avenue 67 370 Payne Avenue to Route 4 70 590 Camino Diablo Road Marsh Creek Road to Byron Highway 60 100 Clayton Road Kirker Pass Road to Marsh Creek Road 66 320 Crow Canyon Road Alameda County Line to Bollinger Canyon road 73 930 Cummings Skyway Route 80 to Route 4 65 270 Cypress Road Route 4 to Laurel Road 66 320 Laurel Road to Sellers Avenue 69 500 Sellers Avenue to Bethel Island Road 67 370 Danville Boulevard Rudgear Road to Stone Valley Road 62 160 Stone Valley Road to El Portal 60 100 Delta Expressway Route 4 to Laurel Road 77 110700 Laurel Road to San Creek Boulevard 76 930 Sand Creek Boulevard to walnut Boulevard 74 1,100 Walnut Boulevard to East 71 680 Dougherty Road(Realigned) 80 410 Gateway Boulevard Near Route 24 68 430 Near Moraga Way 67 370 Kirker Pass Road Concord Boulevard to Railroad Avenue 73 930 Laurel Road Delta Expressway to O'Hara Avenue 69 500 O'Hara Avenue to Route 4 68 430 Route 4 to Cypress Road 64 230 11-11 11.Noise Element TABLE 11-2 (Continued) Distance to DNL at 100 ft. 60 DNL Contour Road/Segment (dB) (feet) "' Marsh Creek Road Clayton to Deer Valley Road 65 270 Deer Valley Road to Camino Diablo Road 64 230 Camino Diablo Road to East 63 200 Lone Tree Way Empire Mine Road to O'Hara Avenue 68 430 O'Hara Avenue to Route 4 60 100 Pacheco Boulevard Pine Street to Morello Avenue 61 130 Morello Avenue to Route 4 65 270 Route 4 to Concord Avenue 66 320 WNW Pleasant Hill Road Reliez Valley Road to Oak Park Boulevard 69 500 Port Chicago Highway -- Pacifica Avenue to Willow Pass Road 64 230 Richmond Parkway 72 800 San Pablo Avenue Route 80 to Rodeo 67 370 Pinole to Richmond 63 200 San Pablo Dam Road San Pablo Avenue to Appian Way 70 590 Appian Way to Valley View Road 63 200 Valley View road to Castro Ranch Road 64 230 Castro Ranch Road to Bear Creek Road 67 370 Stone Valley Road Route 680 to Miranda Avenue 62 160 Miranda Avenue to Green Valley Road 61 130 Camino Tassajara Road Black Hawk Road to Finley Road 61 370 Finley Road to Alameda County Line 66 320 Taylor Boulevard Pleasant Hill Road South to Pleasant Hill Road North 68 430 Vasco Road Camino Diablo Road to Alameda County Line 71 680 Willow Pass Road Route 4 to Pittsburg 65 270 W indemere Parkway 65 210 "" Ygnacio Valley Boulevard Walnut Creek to Clayton Road 70 590 Nam 11-12 -- 11.Noise Element TABLE 11-2 (Continued) Distance to 60 DNL DNL at 100 ft.

These guidelines,along with the future noise levels shown in the future noise contours 11-2 The standard for outdoor noise levels in residential areas is a DNL of 60 dB. However,a DNL of 60 dB or less may not be achievable in all residential areas due to economic or aesthetic constraints. One example is small balconies associated with multi-family housing. In this case,second and third story balconies may be difficult to control to the goal. A common outdoor use area that meets the goal can be provided as an alternative. 11-3 If the primary noise source is train passbys,then the standard for outdoor noise levels in residential areas is a DNL of 70 dB. A higher DNL is allowable since the DNL is controlled by a relatively few w" number of train passbys that are disruptive outdoors only for short periods. Even though the DNL may be high,during the majority of the time the noise level will be acceptable. 11-4 Title 24, Part 2, of the California Code of Regulations requires that new multiple-family housing projects,hotels,and motels exposed to a DNL of 60 dB or greater have a detailed acoustical analysis describing how the project will provide an interior DNL of 45 dB or less. The County also shall require new single-family housing projects to provide for an interior DNL of 45 dB or less. ''- 11-5 In developing residential areas exposed to a DNL in excess of 65 dB due to single events such as train operation, indoor noise levels due to these single events shall not exceed a maximum A-weighted Mont, noise level of 50 dB in bedrooms and 55 dB in other habitable rooms. Single event indoor residential noise levels from airport related causes will be 45 dB CNEL. 11-6 If an area is currently below the maximum"normally acceptable"noise level,an increase in noise up -� to the maximum should not be allowed necessarily. 11-7 Public projects shall be designed and constructed to minimize long-term noise impacts on existing residents. MEOW 11-8 Construction activities shall be concentrated during the hours of the day that are not noise-sensitive for adjacent land uses and should be commissioned to occur during normal work hours of the day to provide relative quiet during the more sensitive evening and early morning periods. 11-9 Sensitive land use shall be encouraged to be located away from noise areas,or the impacts of noise on these uses shall be mitigated If residential areas are planned adjacent to industrial noise sources,then a noise study shall be performed to determine the extent of any noise impacts and recommend appropriate noise mitigation measures. -- 11-10 Development located within 6,000 feet of the Camp Parks Reserve Forces Training Area shall be required to prepare a detailed acoustical analysis. The analysis shall determine if the project will be affected severely by noise and,if so,what noise mitigation measures are available. 11-11 Noise impacts upon the natural environment, including impacts on wildlife, shall be evaluated and considered in review of development projects. 11-14 1.Noise Element 11.10 IMPLEMENTATION MEASURES DEVELOPMENT REVIEW 11-a Continue to require a review and analysis of noise-related impacts as part of the existing project development review procedures of the County. 11-b Evaluate the noise impacts of a proposed project upon existing land uses in terms of the applicable Federal, State, and local codes, and the potential for adverse community response, based on a significant increase in existing noise levels. 11-c Encourage use of the following mitigation measures tom* u*w noise impacts ofproposed development projects: 1) Site planning. Proper site planning is the first mitigation measure that should be investigated to reduce noise impacts. By taking advantage of the natural shape and terrain of a site, it often is possible to arrange the buildings and other uses in a manner that will reduce and possibly eliminate noise impact. Specific site planning techniques include: a) Increasing the distance between the noise source and the receiver; b) Placing non-noise-sensitive land uses such as parking lots,maintenance facilities,and utility areas between the source and the receiver; C) Using non-noise-sensitive structures such as garages to shield noise-sensitive areas;and d) Orienting buildings to shield outdoor spaces from a noise source. 2) Architectural layout of buildings. In many cases,noise reduction can be attained by careful layout of noise-sensitive spaces. Bedrooms, for example, should be placed away from freeways. Quiet outdoor spaces can be provided next to a noisy highway by creating a U- shaped development which faces away from the highway. 3) Noise Barriers: Noise barriers or walls are commonly used to reduce noise levels from ground transportation noise sources and industrial sources. While serving a dual purpose in that they can reduce noise level both outdoors and indoors, to be effective, a barrier must interrupt the line of sight between the noise source and the receiver. A barrier should provide at least 5 dB of noise reduction to achieve a noticeable change in noise levels. 4) Construction modifications: If site p *%JZ*ri ,architectural layout,noise barriers,or a combination of these measures does not achieve the required noise reduction,then construction modification to walls,roofs,ceilings,doors,windows,and other penetrations may be necessary. CALIFORNIA ENVIRONMENTAL QUALITY ACT(CEQA)GUIDELINES 11-d Amend the County CEQA Guidelines to define projects that have the potential to increase long-term noise levels above the levels specified in the policy section of this Plan as generating a significant impact on the environment. 11-e Noise mitigation features shall be incorporated into the design and construction of new projects or be required as conditions of project approval. ZONING AND OTHER ORDINANCE AMENDMENTS 11-f Adopt a noise ordinance as the method to regulate noise from sources other than transportation sources. The noise ordinance should include specific noise level limits for stationary sources(i.e., projects). These noise level limits should take into account the type of adjacent land use (i.e., residential,commercial,or industrial). The State of California Office of Noise Control has published a Model Community Noise Ordinance. 11-15 11.Noise Element OTHER PROGRAMS 11-g Coordinate efforts among the County,the cities,BART,the State government,and other agencies to develop a multi-phased action program to mitigate noise impacts. - ._. 11-h Prepare and adopt a noise abatement program that is consistent with State and federal guidelines, legally valid, and cost-effective. 11-16 "� ` or oro Q.cps So Alk lot r 4 O,t v (�� •iia. 1 0 � Of 1.a• � .�++ app ` ��� �' V+ '� d � o a�M....l Vo-- yIt � fit, CD MV CD �a PU t y o•, 0 0 �/ `�tom„ d 6 ISO 3 1 g, lid 37 PW 1015 o 0• ap " iL �°� 7 Z� 4 Z 3�* u Q Flo O- G `� ,' o v � • moo ? � N N a -a U) d) UW WOW!

Figure C-1 illustrates the concentrations of Welfare-to-Work participants and the relationship with public transit job centers, and community facilities. Typically,people on welfare are most vulnerable to becoming homeless in case of an economic recession or cut in public assistance. In siting emergency shelters and transitional housing, the County will pay special attention to the geographic relationships between needs and access to services and employment. Another guiding principle is the avoidance of over-impacting a particular neighborhood with such facilities. 13-13 Nomm APPENDIX D RESIDENTIAL DEVELOPMENT APPLICATIONS CONSIDERED FOR REZONING TO THE P=1 ZONING DISTRICT SINCE JULY 1996 Table D-1 on the following page summarizes the residential development applications considered for rezoning to P-1.
