RECOMMENDATION ' It is recommended that: ' a. The existing Drainage Fee Ordinance (No.98-58) for Drainage Area 52D be repealed; ' b. A new drainage fee ordinance reflecting cost increases for the detention basin right-of-way and construction be adopted; and ' c. The drainage plan for Drainage Area 52D be amended. 2. DRAINAGE AREA LOCATION AND DESCRIPTION ' Drainage Area 52D is located in the East County in the Oakley Area. A portion of the drainage area is within the incorporation limits of the City of Oakley. The drainage area is bounded by Marsh Creek to the west, by the Atchison Topeka and Sante Fe Railroad to the east, Cypress Road to the north, and the extension of Hill Avenue to the south. The exact boundary is shown on Contra Costa County Flood Control and Water Conservation ' drawing FD-12630. The drainage area contains approximately 240 acres. The General Plans for the area ' designate about 140 acres in the north as residential with 7 to 12 units per acre and the remaining area in the south as agricultural residential. ' 3. REASON FOR THE CHANGE OF PLAN AND DRAINAGE FEE ORDINANCE The plan is being changed to reflect conversion of the South Basin to off-site storage ' thereby reducing the amount of basin area required. The South Basin will be intersected by the future extension of Laurel Road over the Atchison Topeka and Sante Fe Railroad. To compensate for the storage lost due to the road embankment additional basin area ' would have to be acquired or the basin would have to be converted to off-site storage which is more efficient. The off-site storage option is recommended. The proposed amended plan is shown on District drawing FC-13067. ' The current fee of$ 0.66 per square foot of new impervious surface is insufficient to cover the estimated project costs and the long-term debt for the basin right-of-way that ' was purchased over ten years ago. 1 4. COST ESTIMATE A detailed engineer's estimate is attached as Appendix A The following is a summary of these costs: Construction $905,000.00 ' Rights-of-way(incl. debt) $865,000.00 Engineering and Administration $203,000.00 ' Total Subregional $1,973,000.00 Marsh Creek Regional Share $104,000.00 Total Costs $2,077,000.00 5. CALCULATION OF THE NEW FEE As indicated above the total cost to implement the remaining portions of the proposed plan and funding the drainage areas indebtedness for the Basin #2 right-of-way is $2,077,000. The estimated amount of impervious surfaces to be constructed in the future ' in this drainage area is 2,590,000 square feet. The required fee is calculated by dividing the estimated cost by the estimated quantity of new impervious surface area. This yields a fee amount of$ 0.80 per square foot of new impervious surface. ' Development types and densities are based on the City and County General Plans and Specific Plans. The amount of impervious surface for the various types of development is based on the Contra Costa County Flood Control and Water Conservation District report entitled "Report on Impervious Surface Drainage Fee Ordinance" dated January 5,1982 The fee schedule is shown in Exhibit A attached to this report. ' 6. FUTURE UPDATING OF PROPOSED FEES ' The standard impervious surface drainage fee ordinance has been modified to include a paragraph that authorizes annual fee updates using the Engineering News Record Construction Cost Index. The updates will occur annually on January 1. The new ' paragraph is Section X, Review of Fees. 7.CALIFORNIA ENVIRONMENTAL QUALITY ACT An initial study of environmental significance was prepared for the formation of the drainage area and the adoption of the original plan and fee ordinance. An addendum to this document was prepared to address the environmental impact of the proposed improvements that would result from the proposed Drainage Plan Amendment No. 2.

This Board finds and determines that said drainage area ' has inadequate drainage facilities; that future subdivision and development of property within said drainage area will have a significant adverse impact on existing and future developments; that development of property within the drainage area, with its resultant ' increase in impervious surfaces, will require the construction of facilities described in the drainage plan; that the fees herein provided to be charged are uniformly applied on a square foot of impervious surface basis and fairly apportioned within said drainage are ' on the basis of benefits conferred on property upon which additional impervious surfaces in said drainage area are constructed; that the estimated total of all fees collectible hereunder does not exceed the estimated total costs of all drainage facilities tshown on the drainage plan or included in the Engineer's Report; and that the drainage Ordinance No. Page 1 of 5 facilities planned are in addition to existing drainage facilities already serving the drainage area at the time of the adoption of the drainage plan. SECTION III EXEMPTIONS. The fee shall not be required for the following: 1) to replace a structure destroyed or damaged by fire, flood, winds or other acts of God, ' provided the resultant structure has the same, or less impervious surface as the original structure; 2) To modify structures or other impervious surfaces, provided the amount of ground coverage is not increased by more than 100 square feet; 3) To convey land to a ' government agency, public entity, public utility, or abutting property owner where a new building lot or site is not created as a result of the conveyance; or 4) Any lot or property for which drainage fees have been fully paid previously. ' SECTION IV. FEE DEFERMENT. On lots greater than two acres in size, the property owner can defer the payment of the fee on the portion of the lot in excess of ' two acres that is not a required part of the pending development. The deferment of fee is conditional on the property owners granting, as collateral, the development rights to the Board of Supervisors for said area of deferred fee until such time as the fee is paid. SECTION V. BUILDING PERMITS. Except as permitted under Section III and IV, ' the Contra Costa County or the city official having jurisdiction shall not issue any building permit for construction within the drainage area until the required drainage fee has been paid. For initial construction the fee shall be as set for the in Section VII. For ' single family residential swimming pools on lots for which the drainage fee has not been paid, the fee shall be $704.00 per pool. For other construction, modifications or replacements to an existing facility that cause an increase in impervious surface, ' including, but not limited to, driveways, walks patios, etc., the amount of net increase in impervious surface shall be subject to a fee of$.80 per square foot, but not to exceed the amount required under Section VII. ' SECTION VI SUBDIVISIONS. Except as permitted under Sections III and IV, the subdivider shall pay the drainage fee on the entire proposed subdivision or on each ' individual unit for which a final or parcel map is filed prior to recordation of said map. Town house, condominium, and cluster housing type subdivisions creating individual lots less than 4,000 square feet shall be treated as multifamily residential and the lot ' size used in determining the "square feet of land per unit" shall be the lot size prior to subdividing. Except as noted above, the fee for all other subdivisions shall be calculated on an individual lot basis. The fee amount shall be as set forth in Section VII.

' This document serves as an Addendum to the ND for Drainage Area 52D Formation-(CP# 88-82; SCH# 89022112). The ND for the project consists of the ND, and this Addendum. The Contra Costa Community Development Department (CDD) is the lead agency ' for the project, and on June 13, 1989, the Board of Supendsors (Board) as the Goveming Board for the Contra Costa County Flood and Water Conservation District(FCD) approved the project and filed a Notice of Determination (NOD) with the County Clerk. CEQA PROCESS ' The California Environmental Quality Act (CEQA) prescribes that an Addendum (CEQA Guidelines Section 15164) to a previously adopted ND may be prepared if only ' minor technical changes are necessary and none of the conditions described in CEQA Guidelines Section 15162 have occurred: ' 1. No substantial changes are proposed in the project which will require major revisions of the previous ND due to the involvement of new significant environmental effects or a substantial increase in the severity of previously ' identified significant effects; 2. No substantial changes with respect to the circumstances under which ' the project is undertaken which require major revisions of ND due to the involvdment of new significant effects or a substantial increase in the severity of previously identified significant effects; or 1 ' 3. No new information of substantial importance shows that the project will have one or more significant effects not previously discussed in the ND. ' In accordance with CEQA Guidelines Section 15164(d), the Board shall consider this Addendum along with the ND prior to making a decision on the project. According to CEQA Guidelines Section 15164(c) an Addendum does not require circulation for public review but can be included in or attached to the ND. As noted in the Preface, this Addendum is attached to the ND for Drainage Area 52D Formation (CP# 88-82, SCH# ' 89022112). ' EXPLANATION OF THE ADDENDUM This Addendum to the ND for Drainage Area 52D Formation identifies minor technical changes in the project design. ' A. DESIGN The drainage area plans are being changed to accommodate the future extension of Laurel Road and to better conform to the tentative map of a subdivision in the planning ' process. The extension of Laurel Road will require Detention Basin # 2 to be split to allow for road right of way. The changes in the configuration of Basin # 2 also require a reconfiguration of the storm drain network that drains to and from the basin. The alignment of several drainage lines is being altered to conform to the tentative map for a subdivision. Table 1 summarizes the minor technical changes in the attached Draft Engineers Report. 1 Table 1 - Technical changes in DA 52D Plan ' Original facility Amended Facility Basin#2 Basin#2 ♦ 1 basin 7.0 acres ♦ Basin split into 2 sub-basins (total area 4.5 acres) ♦ slope 4:1 to accommodate future expansion of Laurel Rd. ♦ Depth 5' ♦ slope decreased to 5:1 ♦ Outfall 18"spiral ribbed pipe (SRP) ♦ Depth increased to 6' ' ♦ Outfall changed to 48"cast in-place concrete pipe (CIPP) ' Basin#3 Deleted-Removed due to lack of conformance with revised General Plan Line Al Deleted - Will be installed as part of conditions of approval for subdivision (7797) w/ existing tentative map.

' This Addendum is consistent with County policies and does not lead directly or indirectly to significant physical changes in the project, nor does it alter the adequacy or the completeness of the environmental impacts and mitigation measures identified in the ND. Therefore, this Addendum to the ND is appropriate. ' ADDITION TO THE ND This section identifies the language which is added/or changed (bold face type)or deleted (stdkeeu )to the text and figures of the ND. The environmental impacts are discussed in "Initial Study of Environmental Significance Supplemental Information for DA-52D", dated Jan. 24, 1989 (attached). The changes below pertain to the document referenced above. p 1 2' para 2nd sentence - Since the basin will be constructed underground with ' 4494 (5 to 1) side slope it will not result in unstable earth condition, disruptions, and displacement. P. 1 2nd para 3' sentence - Since the basin is only five (sixl feet deep, the changes in geologic substructures and topography will be insignificant. p 2 41' para 2nd sentence - The proposed detention basin less has the potential to become a recreational fasilit+es(facility) in the future. ' 3 t ' CONTRA COSTA COUNTY ADDENDUM FINDINGS for the NEGATIVE DECLARATION for ' DRAINAGE AREA 52D FORMATION ' The following information is added to the previous ND and is presented to comply with Section 15091 of the CEQA Guidelines for the ND for the DRAINAGE AREA 52D FORMATION project. 1. Environmental Effect: Modifications to the design section as described on p. 2 of ' this Addendum, are minor technical changes or additions to the project and will not result in any additional environmental effects not previously discussed. ' Findings: There are no significant environmental impacts associated with the minor technical changes or additions for the proposed activity for which this ' Addendum was prepared. Statement of Facts: a. The project to be developed pursuant to this Addendum to the ND for DRAINAGE AREA 52D FORMATION project is substantially similar to the project tanalyzed in the ND. b. The ND for the DRAINAGE AREA 52D FORMATION project consists of the ND, ' comments received, responses to the comments raised, and this Addendum. The ND was completed in compliance with CEQA. c. There are no substantial changes, pursuant to CEQA Guidelines Section 15162 ' (a)(1), in the project which require major revisions of the ND due to the involvement of new significant environmental effects or a substantial increase in the severity of ' previously identified significant effects.

There are no substantial changes.with respect to the circumstances, pursuant to CEQA Guidelines Section 15162 (a)(2), under which the DRAINAGE AREA 52D FORMATION project is undertaken which require major revisions of the previous ' ND due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects. Those circumstances remain substantially similar to the circumstances analyzed in the ND. ' e. There is no new information of substantial importance, pursuant to CEQA Guidelines Section 15162 (a)(3), which shows that the project will have one or more significant effects not previously discussed in the ND. 4 1 ' f. None of the conditions calling for the preparation of a subsequent or supplemental EIR have occurred (see items 1 c - e above). Therefore, it is appropriate to adopt this Addendum to the ND to make some minor technical changes or additions found on p.2 Section A of this document (CEQA Guidelines 15164). This Addendum shall be considered along with the ND prior to the Board making a decision on the minor technical changes or ' additions to the project, and in considering these changes or additions, the Board is considering the identical or substantially similar underlying project. 1 The findings are supported by substantial evidence in the administrative record and are based on the ND for the DRAINAGE AREA 52D FORMATION project which was subject to public review. ' In accordance with CEQA Guidelines Section 15164(d), the County Board of Supervisors shall consider this Addendum along with the.ND prior to making a decision on the project. t According to CEQA Guidelines Section 15164(c) an Addendum does not require circulation for public review but can be included in or attached to the ND. As noted in the Preface, this Addendum is attached to the ND for the DRAINAGE AREA 52D ' FORMATION project (CP# 88-82; SCH# 89022112).

As a result of this analysis, each item on the checklist was found to be insignificantly affected by the project. ' The tents provided in this attachment support this finding. Field - Verified Items: 1 a,b,c,d. The proposed project includes a detention basin. Since the basin will be constructed underground with 4 to 1 side slope, it will not result in unstable earth condition, disruptions, ' and displacements. Since the basin is only about five feet deep, the changes in geologic substructures and topography will be insignificant. ' 1 e,f. Since the basin wi11 reduce peak flows before discharging into Marsh Creek, erosion and deposition of soil into Marsin Creek will be insignificant. 1 g. Since the basin cuts are sur-racial geologic hazards .ca.n be considered insignificant. 3 a. Currently, the drainage fry Drainage Area 52D drains into the Knightsen area causing substantial flooaing in there. ' The proposed drainage plan will intercept. ;aid drainage, detain it in the basin and disrl�arge into t t?`=n CrenJt, thus reducing flood problems in jau sghtsen and Dra=r- ge area 52D. The proposed plan will not affect existing irrigation ' facilities. 3 b. Since the project will not create hard surfaces, absorption ' rates will not be changed. 3 c. Since there are no defined aster cou—Ses or cater t rays in that area, the proposed project will not alter the course or ' flow of flood water significantly- 3 d. The proposed pipes will not significantly change t!-ie drainage patters or rate of surface runoff sinceo surface drai age swales will be used along the pipelines. 3 e,f,g. The proposed pipes will be irpervi.ous to rrcund:•,ater in- trusion. 3 h. The surface flood water will be reduced by installing ' pipelines. The reduction of surface water is mitigated by holding this water in a detention basin which will provide access to free grater, open space and groundwater recharge. 3 i. Since the basin will be constructed with- sufficient free board, there will not'be any crater related hazards. ' PAGE 1 OF 3 - t 4 a,c,d. Surface flows which support plant and aninal life vrill remai ' unaffected. The proposed pipes will drain the coil et.tio) points where the surface runoff would.otherwise inundate. Ii addition, most of the project's proposed pipelines will b installed under the paved right of way. 8. The proposed drainage plan was designed as per the Oakle, Area General Plan. ' 18. Since all the proposal pipes and detention basin will be placed below ground, there will be no obstruction of an scenic vistas. 19. Since there are no existing recreational facilities in the area, the proposed plan will not iuPact any recreation] opportunities. The proposed detention basin less/,:.:the potential to be=rp- a reactional facilit-res in the future. �Y rOverlay - Verified Items: 4 b, 5 b. Overlay number 5, "Rare and Endangered Species" does nor- shot, any endangered species of plants or animais which inhabit the area of the proposed proj ec-t. - 13 c, d. The existing transportation systems as shc:•in on overiay number 17, "Major Roads", should not be affecred by the proposed project. Ten=rary Construction Related Items: - These particular items are_ affected on a snort-term basis cniy duri c ' construction of the proposed project- since ' they are only temporary impacts, they were found to be insignificant. 2 a,b,c. During construction of the proposed project, a-_,.-..all amounr of dust may occur at the project site. A dust palliative anc water should be used to ensure this dust is insignificant. In addition, the County's construction specifications include tmeasures for reducing dust. 6 a,b. The noise generated by .the construction equiF:-�t ' minimized by operating muffled machinery only c:. --;--.9 ; :.a1 working hours. The County's construCdicn •ccs- z,,Li cnz r.�e include asures for reducing cdnstructicn roi-:`. ' 13 a,b,e, f. During construction, traffic flc.w will 'te .: highest possible level by miniruzing the encr:cc:�-anr construction equipment into the traveled right-ot-::a�i. ' County's construction specifications include measure providing adequate traffic control during construction. ' Outside Report Item: _ 20 a, b, c, d ' - PAGE 2OF3 - The Northwest Information Center performer an archaeological records ' search for the proposed project site which consisted of a review :of ethnographic, historical and archaeological maps and literature on file;at the Northwest Information Center at Sonoma State University. The research suggests that the area contains one recorded prehistoric archeological site ' but no cultural resources. There is, however, the possibility that prehistoric cultural resources exist within the project area. Should any cultural, features such as human interments, hearths, artifacts, etc. be encountered during construction, work should stop within a 100-foot radius from the find and an archaeologist should be consulted immediately regarding ' steps which horst be taken before continuation of work. Other Items: The remaining ni ng items -on the Initial Study form are not significantly ' affected by this project clue to the type of project being proposed. 7. This project will not produce light or glare. ' 9 a. This project will not s ignif is=ntly inCIL-eaSe the rare of use of any natural resource. ' 10 a,b..
