Bragdon Director of Community Development (J�V DATE: April 15, 1987 County SUBJECT: Progress Report on the Comprehensive General Plan Review Program SPECIFIC REQUEST S) OR RECOMMENDATIONS(S) & BACKGROUND AND JUSTIFICATION RECOMMENDATIONS 1. Accept the report on the progress of the General Plan Review Program from the Director of Community Development. 2. Accept the Report "Recent Growth in Contra Costa County, the San Francisco Bay Area, and California". FINANCIAL IMPACT None. BACKGROUND This is a brief report to update Board members as to the progress made by the 67 member Planning Congress, its three subcommittees, staff and consultants in revising the Countywide General Plan. As the General Plan Review program enters the most crucial phase this Spring, our office will continue to make monthly progress reports to your Board. Report on Recent Growth Trends As part of the technical work that is being prepared for the updated General Plan, staff has put together a brief report summarizing recent growth in the County and State. The report, Recent Growth in Contra Costa County, the San Francisco Bay Area, and California, documents the number of new housing units that have been completed in each jurisdiction in the County during 1986, as well as construction trends since 1980. The report also discusses recent population growth in the County and San Francisco Bay region, and places Contra Costa growth in a statewide context. We hope you will find the report to interesting reading.

Most of the work to date, however, has been accomplished in the three subcommittees organized by the Congress: Jobs/Housing; Infrastructure; and Agriculture/Open Space. In addition, the Water Policy Task Force, appointed by the Board previously, is technically a subcommittee of the Congress. As subcommittees debate and adopt specific goal and policy language, these documents are referred as "Position Papers" to the larger Planning Congress for approval or modification. The first Posi- tion Papers from the subcommittees were considered by the Planning Congress at their March 19th meeting. Copies of these papers, as adopted by the Congress, are included as Attachment A. A second set of Position Papers has been prepared by the Jobs/Housing, Agriculture/Open Space, and Water Task Force subcommittees and will be heard by the Planning Congress at their meeting next Thursday, April 23rd. These papers are also included in Attachment A. Specifically, the Jobs/Housing Subcommittee has been using a map-oriented approach, as the group designates those areas of the County which are not appropriate for development and begins the process of designing alternative land use scenarios to be tested for impact analysis. The subcommittee has also discussed the concept of a jobs/housing balance extensively, and has adopted a working definition for the plan ( see the subcommittee' s paper) . The Infrastructure Subcommittee has been meeting on almost a weekly basis immersing itself in technical background information dealing with services ranging from transportation to child care to flood control. The committee has adopted several specific policies regarding transportation, which call for increased cooperation between the County and cities when defining "level of service" standards, especially in downtown areas. The group has endorsed the concept of widening some roads (e.g. Route 4) , while focussing primarily on methods to increase multiple-occupancy vehicles, such as Transportation Systems Management (TSM) pro- grams. The Agriculture/Open Space Subcommittee has adopted numerous goal and policy statements regarding the preservation of agricultural operations in the County. These policies were drafted by one the planning consultants and have been modified by the committee over the course of several meetings. After concentrating almost exclusively on agricultural issues, the group began this month to discuss goals relating to Open Space and Conservation issues. The planning consultant team hired by the County, headed up by Duncan & Jones, has been actively working with Congress members and staff. Most recently, the consultant has prepared a detailed questionnaire asking for individual committee members ' opinions regarding a whole gamut of growth and growth management issues facing the County. The results of this survey will be discussed by the consultant at the Congress meeting on April 23rd. The consultant has also completed an initial Issues Identification Paper which summarized the previous debates that occurred at the Congress. Technical Work on the Countywide Data Base While the citizens committees have been meeting diligently, the County staff and planning consultants have been working hard to compile an ambitious data base for the entire County. This data base includes detailed demographic, housing, economic, and infrastructure information and will serve as one of the main inputs to the General Plan transportation model. The information a Page 3 is being aggregated at a very fine level: the incorporated and unincorporated areas of Contra Costa County have been divided into 517 individual traffic zones. At this level of detail, the County will be able to forecast future traffic volumes on each link of every major arterial in the region. The first phase of compiling the extensive data base has been completed on a microcomputer in the Community Development Department for the base years of 1980 and 1985. The data will be further refined as we receive corrections and additions from the cities during their review period (see below for a discussion of the cities' role in the process thus far) . The next step, to begin later this month, will be to calibrate the transportation model prepared by Barton-Aschman Associates to the two earlier years. By making sure the model is accurately predicting traffic levels for 1980 and 1985, we increase our confidence in the results of later forecasts. Following calibration of the computer model, staff will build upon the existing data base by inputing data regarding recent and tentative approvals of projects in the cities and County. A first report from the transportation consultants to the Board and Congress will forecast future traffic levels in the County based upon the impacts of already approved projects. Further runs of the transportation model will be based upon the generalized land use alternatives considered by the Planning Congress sub- committees. Several possible land use alternatives have been adopted by the Congress as outlined in the Jobs/Housing Position Paper #1 ( see Attachment A) . The data base that has been developed will also be used to evaluate and forecast infrastructure service needs. Because growth management will be a critical component of the updated General Plan, it is anticipated that a detailed permit management system tied to service constraints and opportunities will be required, which will be based upon the data base prepared during this plan revision. The computerized data base will also serve a third important function: to allow staff and consultants to analyze the fiscal impacts of new land uses. In conjunction with the need to more efficiently plan urban development to minimize new expenditures on infrastructure systems, the County and cities must agree upon a method to assess the relative costs and bene- fits to all jurisdictions of specific General Plan changes or large development projects. By continually updating the data base that has now been prepared, the County should have the means to analyze the infrastructure and fiscal impacts of land use changes on a local, subregional, and regional level. Coordination With the Cities in the General Plan Review Program The eighteen cities in the County have been actively involved in the General Plan Review program through their representation on the 67 member Planning Congress. In addition, city planning staffs have been kept appraised of the technical work being completed by County staff and consultants. To date, there have been two formal meetings held with the city planning directors and staff on February 12th and March 26th. During the February meeting, information regarding the County' s program and similar General plan revisions underway by individual cities were discussed. On March 26th, the city representatives each received the raw demographic and housing data, in the form of computer printouts, which have been developed by County staff for each jurisdiction and their Sphere of Influence area. As men- tioned above, the city staffs are now in the process of reviewing the County' s data base to correct any mistakes or deficiencies. The County has also requested from' the cities information regarding recently approved and pending development projects, to assist us in the first transportation model run. Page 4 At both meetings with city planning staffs, informal discussions pinpointed specific steps that can be taken to better coordinate planning efforts between the County and cities. Most of the participants felt the sharing of information was extremely valuable, and it was decided that future meetings will be regularly scheduled to keep the city staffs involved in the process. Also, copies of these progress reports to the Board will be regularly sent to the cities. The next scheduled meeting with city representatives will be held on April 23rd with the public works directors and/or traffic engineers, to review the computerized transportation network and links prepared by Barton-Aschman Associates. Coordination of land use and transportation planning between the jurisdictions has been identified as a criticial issue by Planning Congress members. At the Congress meeting scheduled for later this week, April 23rd, the group will be discussing for the first time the concept of "metering" development permits in conjunction with infrastructure improvements. Other growth management tech- niques will be formally debated at future Congress and subcommittee meetings. The six jurisdictions of North Central Contra Costa County (Martinez, Pleasant Hill, Concord, Clayton, Walnut Creek, and the County) have also been actively promoting closer coordination through participation at the TRANSPAC (the Central Contra Costa County Transportation and Land Use Partnership) organization. Phase I of the TRANSPAC work program has been completed and the specific recommendations in the Phase I report will be forwarded to the Board for their adoption in the near future. TRANSPAC members have recently debated whether to hire a consul- tant to prepare a transportation model for the area or whether to use the model being developed for the Countywide General Plan Review. At this point, the group has made a preliminary decision not to duplicate the County' s effort, but to piggyback their transportation planning efforts on the Barton-Aschman model. The city staff members involved in TRANSPAC will carefully monitor the data and assumptions that are being input into the County computer model and, hopefully, the policy makers of the six jurisdictions will agree to use the one model to analyze and resolve subregional planning issues. Individual cities will continue to rely upon their own more detailed traffic models to determine impacts upon specific locations and intersections. Our department will continue to keep_ the Board informed of all relavent policies and position papers that are adopted by the Planning Congress, as well as all major work papers that are prepared by staff and consultants. CONTRA COSTA COUNTY COMPREHENSIVE GENERAL PLAN REVIEW PLANNING CONGRESS Agriculture/Open Space Subcommittee Position Paper No. 1 The following goal and policy statements regarding the issue of Agricultural Economy have been adopted by the Subcommittee. The statements have been modified from the first installment of a consultant's report. Further issues will deal with Agriculture/ Urban Conflicts, Agricultural Land Conservation, and Agricultural Land Preservation. The Subcommittee has not yet adopted policies regarding open space or conservation issues. This paper was slightly revised and adopted in total by the Planning Congress on March 19, 1987. ISSUE 1 - Agricultural Economy Agriculture is an important part of Contra Costa County's heritage, economy, and lifestyle. However, agriculture has declined in im- portance to the overall economy as the County has become more urbanized. Agriculture in Contra Costa County, like many other parts of the State and nation, is undergoing a difficult period, characterized by low commodity prices, high operational costs, competition with other producing areas, and other difficulties. Although the County is not the cause of many of these problems, it can evaluate its programs and regulations that do affect agri- culture and modify these programs and regulations, as well as es- tablish new programs which promote and assist agriculture in a variety of ways. Goal Statement 1 Contra Costa County shall maintain and promote a healthy and competitive agricultural economy. Objective 1.1 -- Promote and market agricultural products grown in Contra Costa County. Policy Options 1. Continue to support the "Harvest Time" Program. ► Page 2 2. Create and support a "Locally Grown in Contra Costa" market- ing program. 3. Permit and support a wide variety of promotional and marketing activities of County-grown and processed products. Objective 1.2 -- Consider agricultural production, processing, and services as an important industry within the County and integrate agriculture into the County's overall economic development pro- grams. Policy Options 1. The Private Industry Council (PIC) should develop programs to assist agriculture provided that such assistance is requested. Individual participation shall be voluntary. 2. The agricultural industry should be as eligible for economic assistance and support as is provided to other industries. 3. To the extent possible, consider the promotion of agricul- ture produced in Contra Costa County as a priority in the disbursement of available County funds. 4. The Board of Supervisors should cooperate with the County's agricultural interests and communicate supportive positions to State and Federal legislative bodies when major legisla- tion is proposed which may affect local agriculture. 5. Contra Costa County should adopt a "Buy American" policy regarding the purchase of agricultural goods. Goal Statement 2 Promote the physical and service infrastructure, public and pri- vate, which supports a viable agriculture production industry. Objective 2.1 -- Contra Costa County shall permit agricultural processing and services businesses in agriculturally designated areas. ' Page 3 Policy Options 1. Allow agriculturally-related commercial and industrial uses to be conveniently and accessibly located in Commercial Agriculture areas, subject to appropriate planning and/or permit procedures. 2 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 having more than one employee but clearly subordinate to on-site produc- tion activities, occupying less than 1/2 acre of land and not adversely affecting agricultural production in the area, are permissible in all agricultural designations, subject to approval 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" . Objective 2.2 -- Support efforts to assure an adequate, quality, and fairly priced water supply to irrigated agricultural areas. Policy Options 1. Identify methods for providing irrigation water at a price affordable by agriculture. 2. Explore and encourage concepts for water conservation and use of reclaimed water in order to extend existing supplies. Objective 2.3 -- Maintain and reconstruct Delta levees to assure the continued availability of valuable agricultural land protected by the existing network of levees and related facilities. T Page 4 Policy Options 1. Seek State and Federal grants- to assist in levee maintenance and reconstruction projects. 2. Identify local financing mechanisms for funding levee improvements. 3. Approve land use policies and other regulations which conserve and protect existing levees. 4. Encourage levee maintenance and construction that is sensi- tive to the preservation of riparian habitat, where feasible. EP:mb:Papernol.ep Slightly revised by Plg. Congr. 3/19/87 c CONTRA COSTA COUNTY COMPREHENSIVE GENERAL PLAN REVIEW PLANNING CONGRESS Infrastructure Sub-Committee Position Paper No. 1 This position paper was adopted with slight modifications by the Planning Congress on March 19, 1987. TRANSPORTATION By consensus, the subcommittee has adopted the following initial performance standards and policy statements for transportation: 1) As an initial effort, the following situations should be explored with the transportation model : a) Evaluate existing land use conditions and transportation network. b) Evaluate land use conditions and the transportation network specified in the existing county and cities general plans. For both situations, the results should identify the network segments that are worse than level of service "D" , the network improvements required to achieve a level of service "D" or better, and the cost of these improvements. Maps produced from this effort should show network segments color-coded to indicate level of service as defined by volume/capacity ratios. The colors should be chosen to represent 5% intervals for levels of service D, E and F. 2) Request that consultants and staff prepare suggestions for defining transportation level of service for CBD (central business district) , urban, suburban, and rural areas. 3) The General Plan should include a strong policy statement encouraging cooperation between the cities and the county when defining level of service standards, particularly for "downtown" areas. I 4) Highway 4 should be improved as shown in Caltrans' I I Route Concept Report. 5) Development of a secondary road system of expressways should be considered as a possible solution to congested freeways. 6) "Densification" is not an appropriate method to encourage an increase in either the passenger per vehicle rate, or the use of public transportation systems. 7) Efforts to reduce peak period traffic congestion should include some widening of roads, but should primarily focus on encouraging use of multiple-occupancy vehicles, with measures such as TSM (transportation systems management) , developing park-and-ride lots, expanding parking at BART stations, and developing bikeways and pedestrianways. 8) Transit service should be supplied for those who need it, and alternative ways to provide transit service should explored, such as dial-a-ride. GRG 3/5/87 Slightly revised 3/19/87 gpu\pptrans i CONTRA COSTA COUNTY COMPREHENSIVE GENERAL PLAN REVIEW PLANNING CONGRESS Jobs/Housing Subcommittee Position Paper No. 1 This position paper was adopted in total by the Planning Congress on March 19, 1987. One of the primary responsibilities of this Subcommittee is the preparation of a draft Land Use Element. The Subcommittee has taken numerous actions leading in that direction. They are outlined below: 1. The Subcommittee concurred in the usage of the existing standardized County land use categories as the basis of future discussion; they, however, reserved the right to change from those categories in the future if they felt they were not accurately reflecting future needs. 2. The Subcommittee decided to utilize the map based approach to deter- mine the initial land use alternatives to be developed for testing. (This approach is to utilize graphic representation of an alternative - rather than starting with goals and policies and creating alterna- tives based on those written goals. This decision was made reflecting the diversity of the County and the differing approaches in estab- lished city general plans. ) 3. The Subcommittee spent extensive time discussing the concept of jobs-housing balance. Upon completion of these discussions the Com- mittee unanimously approved the following two motions: o "The General Plan should support and stimulate housing infill where the jobs-housing ratio shows an overabundance of jobs to housing." o "The General Plan should support and stimulate job infill where the jobs-housing ratio shows an overabundance of housing to jobs." 4. For purposes of interpreting the jobs housing goals listed in #3 above the following definitions and the legal requirement were accepted by vote. o Definition of Jobs/Housing Balance "A jobs/housing balance occurs if people live in housing that is affordable at the wages they earn, and travel reasonably short distance to their jobs and the services they use." -- California Statewide Housing Plan, 1982 o Legal Requirement "In exercising its authority to zone for land uses, a city, county, or city and county shall designate and zone sufficient vacant land for residential use with appropriate standards, in relation to zoning for nonresidential use, and in relation to growth Page 2 projections of the general plan to meet housing needs identified in the general plan." -- Government Code Sec. 65913.1 o Housing Unit "A house, an apartment, mobile home-manufactured housing or other group of rooms, or a single room is regarded as a housing unit when it is occupied or intended for occupancy as separate living quarters, that is, when the occupants do not live and eat with any other persons in the structure and there is either (1) direct access from the outside or through a common hall , or (2) a kitchen or cooking equipment for the exclusive use of the occupants of the unit. The occupants of a housing unit may be a family or other group or persons, or a person living alone." 5. The Subcommittee started its discussion of alternatives which it wished to be tested as part of technical program. A cautious approach to this was taken where three base case situations and one alternative were agreed to for initial analysis and running of the transportation models. The are: o Existing Situation While not really an alternative, this is the existing situation against which all alternatives will be tested. 1985 is the base year for the study. County staff has prepared a 1985 land use inventory of the urbanized portions of the County. This will be the basis for the calibration of the traffic models. Land use information will be calculated from the existing maps and allo- cated to traffic analysis zones. Traffic zones are subsets of 1980 (and where modified, 1990) census tracts, consistent with the MTC Regional Model . There are approximately 165 census tracts and there will be approximately 500 traffic zones. o Modified Existing Situation This base case situation takes the existing situation (discussed above) and adds to it all major projects which have been approved by the city and County planning agencies. The purpose of this is to test the adequacy of the transportation system when all previous approvals which may buildout are also considered. The city plan- ning departments have been requested to assist in the compilation of this material . o City/County Composite Plan (Build Out Scenarios) The Congress is familiar with this map which is at 2,000 feet to an inch; it is the multicolored map which shows the City General Plans translated into County General Plan categories that was Page 3 presented at a previous Congress meeting. The map will be updated to reflect the recently adopted San Ramon General Plan within its sphere of influence. The Danville and Orinda plan revisions are far enough along where they should be included for testing - neither plan revision varies substantially from the County plans which they are replacing. This will form the basis of the calcu- lating of land uses allowed under city and the County General Plan. Where cities have calculated buildout under their General Plans this will be translated into traffic zones for direct input into the traffic models. o Spread Development Alternative One obvious alternative would open new areas to development to balance the amount of job growth shown on adopted General Plans within the County as well as to reflect the major job focus in Pleasanton (Hacienda Business Park) . Obvious locations for con- sideration of major new areas of growth are in the Tassajara Valley and in East County. This would follow the traditional pattern of opening new areas for development as the need for them becomes apparent. This follows the evolutionary growth process the Bay Area has followed to date. Due to municipal and ownership interests in the development of certain lands, this alternative was approved for testing purposes. The Subcommittee recognizes the need to consider other alternatives for testing, but has decided to withhold action on selecting them until the initial results of the traffic model have been released and provide guidance to problems the group on the nature of our transportation. This approach to consideration of alternatives and selection of base case situations was unanimously approved by the Subcommittee. 6. Considerations of Environmental or Practical Constraints In addition to starting the alternative selection process, the Subcom- mittee has been pursuing a constraints analyses of lands upon which it would be necessary to limit development potential . The Subcommittee has considered a range of factors and has made findings that the fol- lowing areas will not generally be designated for urban development. o All existing major and local parklands owned or operated by a public agency. o East Bay Municipal Utilities District owned watershed lands. o The major mineral extraction areas in the Byron and Clayton areas. (Implementation of the Surface Mining and Reclamation Act. ) Page 4 o Major low intensity use State and Federal land holding e.q. , the Concord Naval Weapons Station. (The proposed State College site on Ygnacio Valley Road is specifically not included in this grouping. ) o Marshlands o Existing major water areas, e.q. , San Pablo Bay or Clifton Court Forebay. o The Southeast Contra Costa County area (as recommended by the Southeast Contra Costa County General Plan Review Subcommittee) except for the proposed Byron Airport and Byron Hot Springs areas which were held over for further discussion. 7. In addition to these substantive matters three procedural recommenda- tions were made: o A white paper should be developed, presenting decisions made by the Subcommittee to be forwarded to the General Plan Congress. This report is in response to that decision. o Decisions on non-controversial items will be by consensus, how- ever, votes will be taken on substantive issues, so that the is- sues can be brought to closure. o That a listing shall be maintained by the subcommittee of un- resolved issues to insure that no issues get lost in the review process.

Investigate options for making Agricultural Preserve con- tracts more attractive, such as changes in allowable uses or increasing tax benefits. 3 . Support property tax assessments within agricultural areas based upon its agricultural use, for properties that don' t qualify for the Williamson Act. n ISSUE 3 Agricultural/Urban Conflicts Agricultural and urban land uses conflict in a variety of ways. Agricultural uses may produce noise, odors, flies, and exposure to pesticide/herbicide sprays. On the other hand, urban uses near farms create problems such as trespassing, theft, and van- dalism. Although many of these conflicts are difficult to re- solve, methods are available to limit the creation of future conflicts, and reduce existing conflicts.

Objective 6.1 Require urban developments to establish effective buffers between agricultural and urban uses. Policy Options 1. Require adequate setbacks for any non-agricultural struc- tures located within or adjacent to cultivated agriculture. 2. Where a discretionary development permit is sought within or adjacent to agricultural districts, potential conflicts should be reduced by creation of a natural or constructed buffer between the agricultural and urban land use.

EP/jb EP/paperno2 CONTRA COSTA COUNTY COMPREHENSIVE GENERAL PLAN REVIEW PLANNING CONGRESS Jobs/Housing Subcommittee Position Paper No. 2 Position paper No. 1 of this subcommittee was adopted by the Planning Congress at its March meeting. It included the consideration of environmental or practical constraints to land for development. The purpose of determining constraints is to limit areas for consideration of development potential in the preparation of alternatives that will be prepared for indepth testing. The subcommittee recommended and the Planning Congress concerned with the following areas being excluded from consideration of urbanization: o All existing major and local parklands owned or operated by a public agency. o East Bay Municipal Utilities District owned watershed lands. o The major mineral extraction areas in the Byron and Clayton areas. (Implementation of the Surface Mining and Reclamation Act. ) o Major low intensity use State and Federal land holding e.g. , the Concord Naval Weapons Station. (The proposed State College site on Ygnacio Valley Road is specifically not included in this grouping. ) . o Marshlands. o Existing major water areas, e.g. , San Pablo Bay or Clifton Court Forebay. o The Southeast Contra Costa County area (as recommended by the Southeast Contra Costa County General Plan Review Subcommittee) except for the proposed Byron Airport and Byron Hot Springs areas which were held over for further discussion. The subcommittee has continued its discussion of constraints and has two additional concepts and associated land areas to recommend to the Congress as being included as constraints to "urban" development for the plan alternatives which are to be developed. They area discussed individually below. o Flood Inundation Areas The Committee agreed to limit development potential from major flood inundation areas. For this initial cut, the larger contiguous areas within the 100 year flood hazard area as defined by the Federal Emergency Jobs/Housing Subcommittee -2- Position Paper No. 2 Management Agency have been recommended. The two exceptions are Bethel Island which is currently under indepth evaluation for its urbanization potential as part of a specific plan program and the partially developed lands along the levee perimeter of Dutch and San Mound Sloughs. While there may be additional lands subject to similar limiting factors, the Committee selected these areas as the inital constraint areas due to their logical boundaries and large size. The generalized boundaries are shown on the attached map. The Committee spent over one entire meeting discussing the problems of lowland development and five main issues were identified: - flooding due to runoff and tides - settlement of shallow soils - deep subsidence - liquefaction - flooding potential from a world wide sea level rise. The Subcommittee recommends this action by unanimous vote. Recommendation: Show the areas designated on the attached map as a constraint for conventional urban development. o Extensive Areas Exceeding 26% Average Slopes The subcommittee spent considerable time discussing the impacts of slopes as a constraint to development with the County's engineering geologist. It was decided that extensive areas with slopes exceeding an average of 26% would be recommended as a constraint to be recognized in the development of plan alternatives. The Committee put limitations on the use of this as a constraint; - It only include lands outside of currently adopted city and sewer spheres of influence. - That the boundaries are not meant to be considered precise at this time and are to be interpreted flexibly. That areas designated above 26% slope can be redesignated for development if that is necessary to create logical plan boundaries or if they can be developed in a fashion which meets logical development standards. Jobs/Housing Subcommittee -3- Position Paper No. 2 Based on these limitations, the Subcommittee approved this constraint with only one negative vote. (A display map of the areas will be available at the Congress meeting) Recommendation: Show extensive areas with an average slope over 26% as a constraint outside of city or sewer district spheres of influences and subject to the stated limitations listed above.

More than one half of the gain was the result of in-migration. The jump in population was the biggest one year increase since 1942-1943, when defense industries lured thousands of workers and their families to the state. Almost two thirds (395,000) of the new resi- dents live in the greater Los Angeles-Orange-San Diego metropolitan areas of Southern California. The net increase in the San Francisco Bay Area's population amounted to 80,600 additional residents over the twelve month period (see Table I) .

Some of the fastest growing urban counties in the state are in Southern California, including Riverside (5.6% increase) , San Bernardino (5.1%) , and San Diego (3.6%) . Other counties that are growing faster than the statewide average are located in the Bay Area (Solano and Sonoma) , in the Central Valley (San Joaquin, Sacramento) , in the foothills of the Sierra, and on the Central Coast (San Luis Obispo) . In the two population centers of the state, the six counties of the huge Los Angeles-San Diego magalopolis are growing at a rate of 2.7%, while the nine counties of the San Francisco Bay Area are growing only half as fast (1.4% annually) . Surprisingly, the largest county in the Bay Area, Santa Clara, grew very slowly over the last year (0.5%) , reflecting the continuing slowdown in the electronics industry and other constraints. The most rapidly growing region of California is the Mother Lode country, consisting of the retirement and recreation communities in the Sierra Nevada foothills stretching from Mariposa to Sierra County, including Lake Tahoe. Population Growth in California (1980-1986) Since the U.S. Census taken in April , 1980, California has grown by an incredible 3.3 million residents. The urbanized area in Southern California, consisting of the Los Angeles Basin, Ventura and Orange Counties, and the San Diego metropolitan region, now contains an estimated population of 15.3 million, while the State population has surged to almost 27 million (see Table II) . In contrast, the San Francisco Bay region has grown by almost one half million persons since 1980, representing a 9.4% increase. The Bay Area is now home to 5.7 million residents scattered throughout nine counties. Three counties in the region have grown very slowly over the last six years (Marin, Napa, and San Mateo) , the four largest counties have grown at a rate slightly less than the statewide average of 14% (Santa Clara, Alameda, San Francisco, and Contra Costa) , and the remaining two northern counties (Solano and Sonoma) are experiencing rapid growth as they change from a rural to suburban environment. While Contra Costa's growth rate for the 1980 to mid-1986 period was higher than the regional average, it's inter- esting to note that in the East Bay, Alameda County has added a third more residents (106,600) than Contra Costa (73,500) . 1 TABLE II POPULATION GROWTH IN SELECTED CALIFORNIA COUNTIES (1980-1986) Pop.

Figures have been rounded. -4- Recent Housing Growth in Contra Costa County During the year ending December 31, 1986, almost 7,800 housing units were completed throughout Contra Costa County, an increase of 24% over the previous year. Seventy percent of the new housing completions were in either the traditional growth areas of the North Central cities (Concord, Pleasant Hill , and Walnut Creek) or in East Contra Costa (Antioch, Pittsburg, Brentwood, and Oakley) . Surprisingly, housing growth during 1986 in the San Ramon Valley was only 1,002 units, trailing the West County area (1,365 units) , North Central County (2,648 units) , and East County (2,775 units) (see Table III) . Table III breaks down housing completion data for each jurisdiction by type of unit, categorized as single family homes (either detached homes on separate lots, or attached condominiums or townhouses) and multiple family (apartment) units. It should be noted that the data in Table III measure housing unit completions, i .e. a final building permit, not the issuance of an initial building permit to construct. Thus, the numbers are a very accurate representation of exactly how many units were actually finished and ready for occupancy. Housing construction "hot spots" are illustrated on Map 1, at the end of this report. In Contra Costa County, Antioch has been by far the most active location for new home construction. The city registered an incredible 1,200 units completed during the last year, or a building pace of 100 new homes each month. One out of every six new housing units built in the County last year was in Antioch. Construction in the city was divided roughly equally between single family homes (676 units) and new apartment units (521 units) . Much of the building has occurred in the rapidly growing Southeast Antioch area along Hillcrest Avenue. Several thousand additional units are currently under construction in this area, and a total buildout of approximately 15,000 homes has been planned. In neighboring Pittsburg, a total of 430 apartment units were finished during the last year. New rental housing is being built in Pittsburg, as well as in Antioch, at a very rapid pace. Both cities gave preliminary approval during 1986 to build 1,000 apartment units, some of which are reflected in the completed numbers. In Pittsburg, about 100 single family homes were also added, primarily located in the foothills south of Route 4. The small city of Brentwood experienced a very high rate of growth during the last year. Well over 300 homes were completed in several medium sized subdivisions that have been constructed on the west side of the city. North of Brentwood in the unincorporated community of Oakley, a similar amount of growth (335 homes) has occurred. Oakley's new housing is centered in the large Gateway project (Garrow & Cardinale) , as well as in the later phases of subdivisions being built by the Hofmann Company, Seeno, Woodhill Devel- opment, and others. Development activity is expected to remain strong in both the Brentwood and Oakley areas in the coming years, assuming major infrastructure problems do not constrain growth.

In West Pittsburg, over 300 new units were completed during 1986, including 56 new homes in Kaufman & Broad's California Landing project, 90 homes in Presley's Amber Cove, and another 150 units spread out between the Lynbrook project (Crocker Homes) and Woodhill 's Westwood Village. In Discovery Bay, the planned community of waterfront homes near Byron, 62 units were finished during 1986 by either custom homebuilders or the master builder of the project, the Hofmann Company. North Central County includes the five northern cities along I-680, from Martinez to Walnut Creek, as well as Lamorinda (Lafayette, Moraga, and Orinda) . This part of the County has historically been a high growth area since the 1950's. The cities are now reaching a built out environment, as the last remaining vacant parcels are being developed. In addition, the downtown business districts in some of the cities are being redeveloped with multiple family housing. Surprisingly, the North Central cities of Concord, Walnut Creek, and Pleasant Hill added almost 1,900 units of housing last year, compared to about 2,050 units added in the three East County cities. However, the building activity in North Central County is expected to slow in the coming years. Concord, the largest city in the County, has experienced very strong residential growth recently. Over 300 single family homes were completed in outlaying subdivisions on Pine Hollow Road and elsewhere. An impressive amount of multiple family housing, almost 500 units, was also built, most of which consisted of several large apartment complexes built along Clayton Road, between Kirker Pass and Alberta. In Walnut Creek, over 400 units of apartments were also added to the housing stock. Most of the projects were located in the downtown area, with some construction along Oak Road. New single family development included the Main Chance townhouses north of the downtown. The City of Pleasant Hill added over 500 housing units, with several hundred single family homes finished in subdivisions on the hilly west side of the city. About 150 new senior citizens apartments were also constructed in the large Ellinwood mixed use project. Homebuilding activity in these two cities is expected to slow significantly in the coming years, however, due to slow growth initiatives recently adopted by the voters, as well as a dwindling supply of vacant land for development. A significant amount of housing was also completed in the unincorporated areas within North Central County. Many of the 409 single family units that were finished under County jurisdiction were located at the Pleasant Hill BART station and on nearby Oak Road, and consisted of condominiums designed for nearby office workers. -7- Martinez added 210 units of new housing during 1986, primarily located in the growing John Muir Parkway area just north of Route 4. Several thousand additional units have been planned in this area, as well as a substantial amount of job generating uses. In tiny Clayton, almost no development occurred during 1986, although in the coming year it is anticipated the city will approve final plans for the 1,400 unit Oakhurst Country Club development by Presley Homes, which will eventually double the size of the city. In the older Lamorinda area, a modest amount of development was recorded (approximately 125 single homes) . This portion of the County is effectively built out, except for one isolated pocket of vacant land that could be developed in the near future, the Gateway Valley in Orinda. Although the San Ramon Valley has a reputation as one of the most rapidly growing areas in the Bay Area, the number of homes that have been completed there over the last two years has been consistently lower than in the other three sections of the County. In 1986, the Town of Danville completed only 124 homes, many of which were in one project (Danville Ranch by Braddock & Logan) . However, approximately 1,800 units have already been given prelimi- nary or final approval in the large Sycamore Valley, and several hundred are currently under construction. The City of San Ramon registered 200 new single family units and two dozen apartments. The largest amount of development occurred in the huge 3,700 unit Canyon Lakes project, which is being built in the unincorporated area east of San Ramon by several different companies. Approximately 300 homes were completed in the first neighborhoods of the project, coupled with some building in a nearby Shapell Industries subdivision (New Castle) and an apartment compex (Lincoln Properties' Country Brook) . Upon completion, the units in these unincorporated development have been immediately annexed into the City of San Ramon, under the terms of a tax-sharing agreement worked out with the County. At Blackhawk, the planned community of luxury homes east of Danville in the unincorporated area, custom homebuilding has continued at a steady pace. The project added 266 new homes in 1986. The final phase of the 2,300 unit community is expected to be completed during the next two years. In addition, five other large residential projects in the unincorporated Tassajara area, with a combined total of approximately 2,500 proposed new homes, are in the process of receiving final approval from the County, in a joint review process with the two cities. These developments are expected to be under construction during the late 1980's. In West Contra Costa County, there are two locations where a substantial amount of new development has taken place: Hercules and Richmond. Hercules, a former company town for a dynamite manufacturer, has consistently been one of the fastest growing cities in the State. In 1975, the city contained only 51 residents; the city's population is now estimated at about 12,000. During 1986 the city added over 300 single family homes and 161 apartment units. A similar amount of annual growth is expected to continue through the 1990's. -8- Richmond expeienced a very large increase of 665 housing units during the last year, primarily located in three areas of the city: along the water- front, around the Hilltop regional shopping mall , and along Castro Ranch Road in E1 Sobrante.' Large projects which were active in 1986 included the Brickyard Landing and Marina Bay condominiums at the waterfront; the Hilltop Village condominiums and Hilltop Bayview apartments; and Carriage Hills subdivision by Dame near E1 Sobrante. Other locations in West County which supported a moderate amount of housing development included Pinole, which added 134 units during 1986, and the unincorporated community of E1 Sobrante, with about 50 new homes. Growth Trends in Contra Costa During the 1980's Over the last decade as unincorporated land adjacent to cities has been annexed and developed, and new cities have incorporated, the County's role in approving and servicing new residential areas has shrunk dramatically. In 1980, approximately 43% of all housing completions occurred under County jurisdiction. By the end of 1986, the proportion of development in the unincorporated areas had plummeted to under one quarter (see Figure IV) . FIGURE IV HOUSING GROWTH IN CITIES AND COUNTY (196D-1966) 6 76.5% M F 6 x 0 x 4 04 Cities M e 57% Ob x � G 3 43% x P. 71% 0 2 a 23.5% Unincorporated i x 1 I 9% D 196D 1991 1962 1963 1964 1985 1996 -9- Growth in Contra Costa County has added 35,700 units of new housing since 1980, for an average of 5,100 homes completed each year. But homebuilding during the 1980's has fluctuated wildly consistent with the national economic climate (see Table V and Figure VI) . The decade began on a relatively high note, as 6,240 units were finished in 1980. Housing starts began a nosedive during the next year, however, due to very high interest rates and a national recession. By the end of 1984 the local homebuilding industry had recovered, completing 5,100 new units. The following year saw almost 6,300 homes and apartments built in the County, an increase of 23%. During the most recent year, 7,800 units were con- structed, representing another 24% increase over the previous twelve month period. By examining the housing statistics for each jurisdiction in the County over the last seven years, it becomes apparent that the strong construction activity in North Central County during 1986 has been a consistent pattern for some time (see Table V and Figure VI) . Almost 12,600 housing units have been built in the communities along the northern section of I-680 since 1980, compared to 10,900 units completed in East County, 6,300 in West County, and 5,900 in the San Ramon Valley. The cities that have experienced the most development activity over the last seven years are Antioch (approximately 3,900 new units) ; Concord (3,300) ; Pittsburg (2,850) ; Martinez (2,600) ; San Ramon (2,250) ; and Richmond (2,200) . Other communities that added over 1,000 units since 1980 include Walnut Creek (1,900) ; Pleasant Hill (1,900) ; the unincorporated areas of North Central County (1,700) ; Hercules (1,700) ; unincorporated Oakley (1,500) ; Danville (1,450) ; and the unincorporated communities of Blackhawk (1,250) and West Pittsburg (1,050) . In terms of the type of housing that has been constructed in Contra Costa County since 1980, Figure VII illustrates the change over time of the mix between traditional single family homes on a separate lot, attached condominiums or townhouses, and multiple family apartment units. In 1980, about three quarters (73%) of the new housing built in the County consisted of single family homes, 7% was condos or townhouses, and 20% was apartment units. Over the last eight years, the mix of new housing has shifted significantly away from homes on individual lots toward attached housing (either condos or apartments) . During the construction slowdown of the early 1980's, the percentage of new housing that was detached homes dropped from three quarters of the total to about six out of every ten new units. By the end of 1985, that proportion had shrunk further to about one half, and during the last construction year, for the first time less than one half (42%) of the housing completed in the County was detached family homes. d a W a, d a d � LL. a Q io oti (ap n-effnojCj,L) o1jull ZuTum og asp X jm xogiunN TABLE V ANNUAL GROWTH IN HOUSING UNITS BY JURISDICTION IN CONTRA COSTA COUNTY (1) (1980-1986) Total 1980 1981 1982 1983 1984 1985 1986 1980-1986 ---- ---- ---- ---- ---- ---- ---- --------- EAST COUNTY Antioch 478 361 273 462 267 865 1,197 3,903 Brentwood 36 79 16 5 15 100 327 578 Pittsburg 443 529 246 308 196 596 534 2,852 W.

Townhouses and condominiums together accounted for only 7% of the new housing in 1980. That portion climbed rapidly to about 24% of all new residential construction by 1983, but decreased to about 21% of the total by the end of 1986. Apartment building has flourished during the last two years, with 1,652 and 2,755 units completed in 1985 and 1986, respectively. Apartments represented one out of every five new units during 1980, dropped to only 15% of the total in 1983-1984, and have sharply increased to account for 29% and 37% of all completions during the last two years. However, multiple family construction is expected to weaken in the coming years due to changes in Federal tax laws.
