Continuing the hearing to an appropriate date to allow for staff preparation and Board consideration of draft findings on which to base a disapproval of the two applications . FISCAL IMPACT None . The applicant is responsible for staff costs above 1200 of the initial filing fees for this project . BACKGROUND This appeal pertains to an approximate 45-acre parcel adjoining the east side of the Town of Danville at the southeast corner of the intersection of Lawrence Road and Camino Tassajara. Except for a hill (that the applicant proposes to grade flat) , the site is essentially level . The Board of Supervisors considered an earlier version of this project on May 6, 1997 . At that time, the Board voted 4-1 (Supervisor Gerber dissenting) to: • adopt the Tassajara Meadows General Plan amendment redesignating the 45-acre site from Agricultural Lands to Single Family Residential - High Density and Public/Semi- Public uses; . • rezone the site from Heavy Agricultural, A-3 , to Planned Unit District, P-1; and • approve a preliminary development plan for a 192-unit single family residential development and an 8-acre park/school site. The Board also accepted as adequate for the purposes of compliance with the California Environmental Quality Act (CEQA) , the Camino Tassajara Final Environmental Impact Report, and adopted findings and mitigation monitoring program for the general plan amendment, rezoning, and preliminary development plan approval . It should be noted that while the prior approval was granted for the preliminary development level of entitlement, the information that was included with that application was nearly equivalent to the standard requirements of a final development plan and tentative map applications . The road alignments and designs, and lot configurations were all included with the earlier version of the project . The applicant had elected not to go forward with the hearing on the final development plan and vesting tentative map to allow for preparation of residential design details . Internal Pedestrian Connection - One of the modifications approved by the Board was, at the applicant' s request, the elimination of a pedestrian walkway to join G Court with A Street and provide easier -2- Appeal of The Meadows Project Danville/Tassajara area access to the school/park for residents along the southern tier of the project . The Commission had recommended that the project be conditioned on the provision of such a walkway. The applicant was concerned that such a walkway might constitute an attractive nuisance. Following the Board' s approval, the applicant modified their Final Development Plan and Vesting Tentative Map exhibits to make them consistent with the Board action. Commission Hearing On June 23 , 1997, the County Planning Commission conducted a hearing on the proposed Final Development Plan and Vesting Tentative Map for the Meadows project . The San Ramon Valley Regional Planning Commission also participated in the hearing in an advisory capacity to the County Planning Commission. The modified Final Development Plan and Vesting Tentative Map site plan are virtually identical to the previous Preliminary Development Plan site plan. After completing testimony, the Commission closed the. hearing and continued the matter to allow for submission of design details from the applicant including a House Plotting Plan for the project . On July 8, 1997, after reviewing additional plan documents submitted by the applicant, the County Planning Commission voted 5- 1 (Clark, dissenting; Gaddis, absent) to approve the project . It should be noted that at the Commission' s request, the applicant provided for a 6-foot walkway joining G Court and A Street in the House Plotting Plan, and the project was so conditioned. (See COA #1 of the Subdivision Permit, pg. SUB-5 . ) The San Ramon Valley Regional Planning Commission commented as individual Commissioners on the project . The Regional Planning Commission was also provided an opportunity to act collectively on the proposed project in the event of an appeal, but declined to do so. LETTER OF APPEAL On July 16, 1997, the Community Development Department received an appeal of the Commission' s approval of the project from Wayne Tooker, Jim Blickenstaff (Sierra Club - Bay Chapter) , and Linda Lemon (Save Our Danville Creeks) . The appeal is concerned with several aspects of the project including proposed drainage from the site; effect on protected amphibians; the appearance of the project; and deed disclosure of surrounding activities . APPLICANT RESPONSE In a letter dated July 25, 1997, the Applicant' s legal counsel, dated July 25, 1997 has responded to the points in the appeal letter. DISCUSSION Staff responds to each of the appeal points below. The responses are organized by subject matter rather than the sequence in which they were listed in the appeal letter. It should be noted that the issues that have been raised are similar to ones that were raised in testimony to the Commission. -3- Appeal of The Meadows Project Danville/Tassajara Area A. Water Quality. 1 . Appeal Point - Vague and/or ineffective on-site mitigation for water quality. No on-site detention basin for. . . water quality. The use of grassy swales alone as water quality mitigation is of limited effectiveness. Staff Response - The goal of any storm water plan for construction and long term water quality protection for a watershed impacted by new development, is to reduce or eliminate certain impacts to water quality and local habitat . These are not new ideas within the environmental field. The term BMP or Best Management Practice is used to represent a measure or method used to protect water quality on either a short term (erosion and sedimentation during construction phases of the project ) or perpetual basis (grassy swales which are used to filter pollutants from the roads and yards adjacent to the swale . ) In any case, an impact is defined and a mitigation measure commensurate with the impact is enforced in the conditions of approval . Each storm water plan must be tailored to the contours, soils, habitat and development type . So each plan must fit both the site and its proposed modifications . Measures like dry wells, would not be a good measure to use in an area prone to slides . However, surface infiltration through pavers and other pervious materials may not be unreasonable for ancillary structures like walks and patios . In addition, grassy swales and small wetland basins could be used to reduce or eliminate sedimentation of existing local watercourses and could also filter some pollutants inherent in the introduction of new growth into a watershed. Finally, because these BMPs are contingent on the final site design, staff has allowed for flexibility and innovation. Staff firmly recommends that a complete and cohesive plan to address impacts to water quality be developed. But this concept must be balanced to the allow the developer' s engineers and environmental planners flexibility to create new systems that may be more effective in protecting water quality than the rote methods referred to above. (See COA #120, pg. SUB-36 of the Subdivision Permit) 3 . Appeal Point - Potential for damage to Alamo Creek including . . . contamination from pollutants. Staff Response - Refer to item #1 above . B. Drainage. 1 . Appeal Point - No on-site detention basin for flood control . . . " Staff Response - Build out of the project will result in an increase in impervious surface and therefore an increase in storm water run-off from the site and ultimately, an increase in flow within Alamo Creek downstream. As agreed to by Contra Costa and Alameda Counties, Alamo Creek shall be limited to a maximum flow of 132 .3 cubic meters per second (4670 cfs) at the County -4- Appeal of The Meadows Project Danville/Tassajara area line. To mitigate this project' s increase in storm water run-off, the conditions of approval require that the applicant select one of three options . (See COA #113 and #114 of the Subdivision Permit, pg. SUB-33) The first alternative requires that an on-site detention facility be constructed to reduce post-development flows to pre-development levels . The Development Plan and Tentative Map do not provide for an on-site basin. If a basin were to be constructed, this would require a modification of the Development Plan and Tentative Map. The second alternative allows the applicant to approach and enter into agreements with other developers within the Alamo Creek watershed to size their basin(s) to reduce this projects downstream impacts and insure that the flow at the county line is not exceeded. The applicant would be required to demonstrate that they have obtained all necessary agreements with and rights from those developers that are cooperating with the applicant. A third alternative allows the applicant to drain into the Lawrence Road Benefit District storm drain system. Storm water run-off from this project has been incorporated into the sizing of the Lawrence Road storm drain line . Drainage from this system will be mitigated through the use of downstream detention facilities within the Dougherty Valley project . The applicant will be required to form or annex to an existing benefit assessment district to collect revenue to help maintain the downstream detention facilities . The Flood Control District does not maintain basins less than 18, 500 m3 (-15 acre-feet) in size. If an on-site basin were constructed, it' s size may not meet this criteria. The basin would therefore have to be maintained through some other maintenance entity. The Flood Control District recommends that drainage be mitigated through larger more regional type facilities rather than numerous individual, privately maintained basins. Therefore, the third alternative is preferred. 2 . Appeal Point - Participation in an unmitigated drainage plan for the Lawrence Road Benefit District. Staff Response - The Lawrence/Leema Specific Plan was approved prior to the initiation of hydrology studies for the Dougherty Valley project . The Dougherty Valley drainage study considered the Specific Plan area to be existing development and therefore included in the existing condition flow calculations for Alamo Creek as it enters the Dougherty Valley project . The detention basin plan for Dougherty Valley therefore accounts for storm water run-off from this project as well as the rest of the Lawrence/Leema Specific Plan area. 3 . Appeal Point - Potential for damage to Alamo Creek including severe erosion. . . Staff Response - The conditions of approval require that the applicant retain a licensed geotechnical engineer to perform a study which analyzes slope stability, allowable creek velocity and erosion potential within Alamo creek, downstream of the project, where peak run-off and run-off volume has increased because of the project . -5- Appeal of The Meadows Project Danvllle/Tassajara Area 6 . Appeal Point - Potential for destruction of property and harm to property values south of Danville's planned drainage into Alamo Creek. Staff Response - The conditions of approval require that the applicant submit a drainage study which analyzes existing, interim and ultimate drainage conditions and facilities as well as the feasibility of the plan to provide necessary drainage mitigation. The impacts from existing drainage facilities and implemented mitigation on watercourses downstream of the project and at the County line must also be addressed. C. Impact on Protected Animal Species 4 . Appeal Point - Potential for damage to red-legged frog and Western Pond turtle habitat. Staff Response - The site does not contain any riparian, pond or other aquatic habitat area. A 1995 biotic resources study on which the EIR was partially based reported the lack of any permanent or long term seasonal water habitats on or immediately adjacent to the site, and therefore concluded that the presence of any amphibians or turtles was precluded. (See pg. 4 of the Biotic Survey Report of the Corrie Property prepared by Dr. Samuel McGinnis, August 4, 1995) 5 . Appeal Point - Potential for "take" of red-legged frog. Staff Response - See response to Appeal Point #4 above. D. Visual Impact of Project as Seen From Camino Tassajara 7 . Appeal Point - Weak Conditions of Approval that will allow excessive negative impacts to view-shed along Camino Tassajara. These include allowance of a large number of two (2) story buildings along their frontage and along the eight (8) acre school/park site. Harsh and inarticulate wall massing on sides and backs of houses. Staff Response - The project as proposed and conditioned will result in an attractive view as seen from Camino Tassajara. The applicant has provided a Landscape Concept Plan dated received by the Community Development Department on January 29, 1997, and 5/28/97 Site Plan providing for a min. 38-foot buffer from edge of road along Camino Tassajara. Of the 38-foot buffer, a varied width (23-27 feet) will consist of a landscaped planter area in front of both the proposed school/park site and proposed residential lots. Landscape Improvements in front of the school/park site will have to be determined by the ultimate user of that site. However, for the section of Camino Tassjara abutting the residential lots, the applicant has proposed landscape improvements consisting of a combination of trees (minimum 15-gallon and 24-inch box sizes) shrubs, and ground cover. The planter slopes upwards to the residential lots . The plans also provide for a six-foot decorative soundwall as conditioned (see COA #63 .B. of Subdivision Permit) whose placement would be staggered along the southern boundary of the planter area. -6- Appeal of The Meadows Project Danville/Tassajara area The House Plotting Plan provides for a combination of single- and two-story plans . Eight of the 15 lots backing onto Camino Tassajara will be single story residences.' All of the two-story models are required to incorporate build-out/cantilever designs as indicated on residential design drawings . (See COA #66 .C. of the Subdivision Permit, pg. SUB-22 . ) E . Deed Disclosure Concerning Existing Surrounding Activities 8 . Appeal Point - The need for Deed disclosures of commercial and agricultural uses of properties around project site. Staff Response - The site abuts residential uses to the west and north, and agricultural uses to the east and south. Condition of Approval #58 of the Subdivison Permit (pg. SUB-19) provides for the standard deed disclosure to prospective buyers of nearby agricultural activities . Staff is not aware of any legal commercial activities in the area that might be regarded as a nuisance to prospective residents in the new subdivision. The properties to the south on Lawrence Road were zoned for agricultural use before being incorporated into Danville. It is staff' s understanding that Danville has designated these properties for residential use. ALTERNATIVE ACTION If the Board is not satisfied that required CEQA and project findings can be made, then the Board could consider disapproval of the current applications as provided by Option B above. In this regard, the applicant could re-apply with modified plans which would be consistent with the Board' s approval of the Preliminary Development Plan and modifications which the Board would consider and review and may deem appropriate. TIME LIMIT ON DECIDING APPEAL ONCE HEARING IS CLOSED It should be noted that once the Board closes the hearing on this appeal, state law [Government Code §66452 .5 (d) ] requires the Board to make a decision on an appeal of a decision on a subdivision project within ten calendar days . Failure to act within this timeframe may result in an automatic approval . 'Contrast with the Tassajara Ridge project located immediately to the west in Danville, where the site is elevated above Camino Tassajara and almost all of the residences backing onto Camino Tassajara are 2-story designs . -7- ADDENDUM TO ITEM D.7 Agenda August 5, 1997 This being the time noticed for the appeal by Wayne Tooker, Jim Blickenstaff, and Linda Lemon (Appellants) from the decision of the Contra Costa County Planning Commission on the application of Kaufinan & Broad (Applicants and Owners) for approval of a Vesting Tentative Map to subdivide approximately 45 acres into 192 single family residential lots and an 8 acre school/park site (County File #8000-95); and on the application of Kaufinan & Broad (Applicants and Owners) for approval of the Final Development Plan to allow a 192 detached single unit family residential .project and an 8 acre school/park site (County File #DP 3090-95). Dennis Barry, Interim Community Development Department Director, presented the staff report. Robert Drake, Community Development Department, advised that during the pre-hearing meeting of the parties, both sides were amenable to the suggestion to insert additional language in the Conditions of Approval for the subdivision. Mr. Drake noted that on Page Sub-19, Condition No. 58, titled "Notification of Agricultural Area", in the second paragraph after the word "...activities;" the suggestion was made to insert the following words: of activities and related traffic;". Mitch Avalon, Public Works Department, commented that the parties had also agreed to the suggestion that there be an amendment to the language in the Conditions of Approval, on Page Sub-35, Condition No. 116, regarding erosion potential on downstream properties, but that the language had not been finalized. The public hearing was opened and the following people spoke: Richard Ambrosini, Kaufinan & Broad, 3130 Crow Canyon Road, San Ramon; Linda Lemon, appellant, Save Our Danville Creeks, 522 Zenith Ridge, Danville; Wayne Tooker, appellant, 1641 Lawrence Road, Danville; Jim Blickenstaff, appellant, Sierra Club, 2410 Talavera Road, San Ramon; All those desiring to speak having been heard, the hearing was closed and the Board discussed the issues. Supervisor Rogers requested that Community Development staff respond to the issues Mr. Blickenstaff raised regarding water quality and the desire to have those issues addressed before final approval of the project. Dennis Barry noted that there are specific plan improvements to be met, and an analysis is required before putting water into that system to avoid creating additional erosion problems. Mr. Barry also advised that in the Community Development staff s point-of-view, water quality issues in this 1 instance have been mitigated above the usual and necessary compliance with the final EIR on this project. Supervisor Canciamilla asked what would happen if a detention basin was required, and Dennis Barry and Mitch Avalon both advised that this issue had been addressed in the Conditions of Approval. Supervisor Gerber stated that she would. vote consistent with her previous record on this project, and would not be supporting the motion. Supervisor Canciamilla noted that it was his understanding that the drainage issues had been fully addressed in the Conditions of Approval. He then moved approval of Option A of staffs recommendations and approval of recommendation Nos. 1 through 5, amending recommendation No. 4 to add the suggested language to Condition 58, noting that the modification was mutually agreed upon. Supervisor Rogers seconded the motion, and stated that many elements in the local community supported this project, and the land dedication was an important component of the project. Following further discussion, the Board took the following action: IT IS BY THE BOARD ORDERED that the public hearing is CLOSED; staffs Recommendation Nos. 1, 2, 3, and 5 in Option A are APPROVED; Recommendation No. 4 in Option A is APPROVED as amended; the decision of the Contra Costa County Planning Commission is SUSTAINED; the Appeal of Wayne Tooker, Jim Blickenstaff and Linda Lemon is DENIED; the Tassajara Meadows Final EIR is CERTIFIED as adequate for purposes of compliance with CEQA for the Final Development Plan (County File #DP 3090-95) and the Vesting Tentative Map (County File #SD 8000-95); the Findings and Statement of Overriding Considerations documenting compliance with CEQA is ADOPTED; the Mitigation Monitoring Program is RE-ADOPTED; the Findings in support of the Final Development Plan and Vesting Tentative Map is ADOPTED; and staff is DIRECTED to file a Notice of Determination. 2 FINDINGS AND CONDITIONS OF APPROVAL FOR THE MEADOWS FINAL DEVELOPMENT PLAN, COUNTY FILE NO. DP953090 (Kaufman & Broad - Applicant & Owner) PER AUGUST 5, 1997 BOARD OF SUPERVISORS APPROVAL FINDINGS A. Required Finding: The applicant intends to start construction within two and one-half years from the effective date of the zoning change and plan approval. FiF nding- The applicant has indicated that they intend to commence construction within two and one-half years. B. Required Finding: The proposed planned unit development is consistent with the county general plan. Finding- -The tentative map provides for 192 single family residential lots and an 8-acre park/school site. The park/school site conforms with the public/semi-public designation on the general plan. The proposed number of dwelling units also conforms with the permitted number of dwelling units under the Single Family Residential-High Density designation (5.0- 7.2 units per net acre). The site consists of 27.3 net acres[net acres = (44.4 acres- 8 acres)x 0.75]. Therefore, considering the residential designation portion of the site alone, the general plan allows up to 196 units to be placed on the site. C. Required Finding: In the case of residential development, it will constitute a residential environment of sustained desirability and stability, and will be in harmony with the character of the surrounding neighborhood and community.. Finding- The project will be required to provide varied residential designs and landscaping improvements along roadways. The project has a similar unit density to development occurring to the west of the project, and with planned development elsewhere in the immediate vicinity. D. Required Finding: The development of a harmonious integrated plan justifies exceptions from the normal application of this code.. Finding-The project will be required to comply with additional landscape and architectural design standards that are not typically associated with residential projects that are 'Were the 8-acre park/school site included in the net acreage calculation, the general plan would allow for consideration of more dwelling units. The Meadows Final Development Plan File#DP953090 Kaufman&Broad(A &O) developed under conventional zoning. The applicant is conveying a major portion of the site to the local School District that will help address the local demand for school facilities.

C:\wpdoc\dp953090.eoa RD\ rev.8/5/97-rd FDP-5 FINDINGS AND CONDITIONS OF APPROVAL FOR THE MEADOWS VESTING TENTATIVE MAP APPROVAL, COUNTY FILE #SD958000 (Kaufman & Broad - Applicant & Owner) PER AUGUST 5, 1997 BOARD OF SUPERVISORS APPROVAL FINDINGS A. Growth Management Element Performance Standards 1. Traffic - The proposed development will increase traffic volumes to the roads and intersections in the community, however, the EIR concluded that the traffic impacts would not decrease the level of service at any of the 14 intersections studied in the EIR. Accordingly, the EIR concluded that the project would not result in any significant impacts associated with traffic volumes. 2. Drainage and Flood Control - Condition#71 of the Subdivision conditions of approval requires that the applicant collect and convey all stormwaters entering or originating within the project to an adequate natural or manmade watercourse. The project also lies within the Lawrence Road Benefit District which was formed by the Town of Danville to provide a mechanism to fund or reimburse costs for the construction of utility systems including drainage improvements identified in Lawrence/Leema Road Specific Plan adopted by Danville. Among other facilities, the benefit district will be constructing a storm drain system parallel to Lawrence Road from the southerly project boundary to the southerly boundary of the Lawrence/Leema Road Specific Plan Area. The required storm pipe will vary in size from approximately 42 inches to 54 inches in diameter and will discharge into Alamo Creek. This project will be required to prepare a complete hydraulic study. The drainage improvements will need to be approved by the Danville City Engineer. The site does not lie within a floodplain and no portion Lies within a special Flood Zone of the Federal Emergency Management Agency. Therefore, the project has no significant risk of flood hazard. 3. Water Service -Prior to approval of a final map, the applicant is required to provide evidence to the County that the applicant has obtained a"will serve" letter from the East Bay Municipal Utility District. (Ref. COA#54) 4. Sanitary Sewer Service -Prior to approval of a final map, the applicant is required to provide evidence to the County that the applicant has obtained a"will serve" letter from the Central Contra Costa Sanitary District. (Ref. COA#53.) The Meadows Vesting Tentative Map File#SD958000 Kaufman&Broad-Applicant&Owner 5, Fire Protection-Prior to approval of a final map, the applicant is required to demonstrate that all of the proposed development is located within one and one- half miles of a fire station, or that development within the project that is more than one and one-half miles from a fire station shall be required to provide automatic fire sprinkler systems. (Ref. COA#70.C.) 6. Public Protection -Prior to approval of a final map, the applicant is required to provide funding for a proportional share of the Sheriff facility standard of 155 square feet of station area per 1,000 new residents if determined by the Zoning Administrator to be needed. (Ref. COA#70.D.) 7. Parks and Recreation- The applicant is required to contribute $5000 per residential lot in park dedication fees per tentative agreement with the Town of Danville. This contribution exceeds the normal County park fee requirement, $2000 which alone would satisfy the Growth Management Element Performance Standard of 3 acres per 1000 new residents. These required park dedication fees are earmarked for use by the Town of Danville subject to County disbursement procedures. (Ref. COA#17.) (Ref. Growth Management Element of the General Plan) B. Findings to Approve a Tentative Map Required Finding: The Planning Commission shall not approve a tentative map unless it shall find that the proposed subdivision, together with the provisions for its design and improvement, is consistent with the applicable general and specific plans required by law. FiF nding: The tentative map provides for 192 single family residential lots and an 8-acre park/school site. The park/school site conforms with the public/semi-public designation on the general plan. The proposed number of dwelling units also conforms with the permitted number of dwelling units under the Single Family Residential-High Density designation (5.0- 7.2 units per net acre). The site consists of 27.3 net acres[net acres = (44.4 acres- 8 acres) x 0.751. Therefore, considering the residential designation portion of the site alone, the general plan allows up to 196 units to be placed on the site. 'Were the 8-acre park/school site included in the net acreage calculation, the general plan would allow for consideration of more dwelling units. SUB-2 Findings The project is also required to collect run-off flowing onto and from the project and to convey it to an adequate natural or manmade watercourse. The project also lies within the Lawrence Road Benefit District which was formed by the Town of Danville to provide a mechanism to fund or reimburse costs for the construction of utility systems including drainage improvements identified in Lawrence/Leema Road Specific Plan adopted by Danville. Among other facilities, the benefit district will be constructing a storm drain system parallel to Lawrence Road from the southerly project boundary to the southerly boundary of the Lawrence/Leema Road Specific Plan Area. The required storm pipe will vary in size from approximately 42 inches to 54 inches in diameter and will discharge into Alamo Creek. A combination of collector and local roads are proposed to link into road systems that are being developed in the Town of Danville.

Applicant shall provide an erosion control plan prior to approval of a grading plan. The following interim control measures shall be included in the erosion control plan and employed on site-specific needs in the project area(Identified in the Final EIR): SUB-9 The Meadows Vesting Tentative Map File#SD958000 Kaufman&Broad-Applicant&Owner 0 Conduct grading so as to minimize areas of exposed, erodible material, and avoid concentration of rapidly flowing runoff in unprotected, erodible areas. • Wherever feasible, isolate runoff from ungraded areas, thereby simplifying erosion control and sediment control measures within the graded area. • The erosion control plan may include water bars, temporary culverts and swales, mulch and jute, netting blankets on exposed slopes, hydro seeding' silt fences, and sediment traps/basins. Erosion control requires use of techniques which prevent displacement of soil particles by raindrops, moving water or wind. These techniques include slope design to reduce erosive emergency, use of erosion control blankets and other devices, mulching and establishing vegetation. Sediment control requires the removal of particles which are suspended in moving water. Erosion and sedimentation are natural geologic processes which do not conflict with protection of resource values. The problem arises when grading activities result in increased discharge of runoff and sediment yields that exceed equilibrium conditions and induce instability in stream channels. General Best Management Practices to reduce sediment in runoff waters including the following: Minimize the amount of land disturbance; Install storm drains prior to grading so that sediment is captured during pad grading; - Keep graded slopes as flat as possible. The placement of barriers (silt fences, straw bales) is only partially effective in controlling sediment from exiting the graded area and entering a natural drainage channel. These barriers are ineffective when runoff waters overtop, tunnel under, or flow around the barriers. As a result, drainage control and sediment traps/basins are important components of sediment control. The following criteria shall be used to size sediment traps/basins: Design the sediment basin to accommodate peak runoff from a 10-year storm. 'Technical literature indicates that successful hydro seeding for erosion control requires care in selection of species. Some species of annual grasses are ineffective for erosion control. SUB-10 Conditions of Approval Design the containment system around a specific size soil particle to be removed from moving waters. The U.S. Environmental Protection Agency recommends that particles 0.02 mm or larger be trapped. Provide a long flow path length to ensure the greatest possible opportunity for sedimentation to occur. - Calculate the anticipated sediment yield from a 10-year storm, and provide sufficient storage capacity in the basin to accommodate this volume of sediment. Include a gravel filter in the sediment trap/basin to allow waters to flow through and drain the structure. - Design the depth of the sediment trap/basin for a minimum of at least two feet. - Provide for clean-out and maintenance of storm drain, sediment basin and erosion control facilities throughout the rainy season to ensure effective sediment control. • Because one of the biggest problems with effective sediment control is lack of maintenance, the erosion control plan must have a comprehensive program for inspection and maintenance during the construction period, for several years following construction and for the long-term. The plan shall focus on the winter rainy season and include performance standards and provisions for documenting maintenance activities and funding. • Monitor the effectiveness of the erosion control measures during construction, and for several years thereafter, by sampling runoff. (EIR Mitigation Measure H:lb) Soils and Geohazards 22. In order to reduce the potential impacts of long-term erosion and sedimentation, the project shall incorporate the appropriate design, construction and continued maintenance of long-term erosion control measures.

(Identified in the Final EIR) Examples include the following: SUB-11 The Meadows Vesting Tentative Map File#SD958000 Kaufman&Broad-Applicant&Owner • Construct sediment traps/basins and grassy swales at strategic locations to control sediment. • Revegetate and continuously maintain graded soil surfaces, either through a Geologic Hazards Abatement District, homeowner's association or maintenance district. • Design cut and fill slopes to minimize, as much as possible, the velocity of sheet flow runoff. • Establish performance standards and provide periodic inspection and maintenance of erosion and sedimentation control facilities. • Prior to any excavation, determine whether the depth and extent of excavation would likely encounter contaminated soils and groundwater. • Native vegetation shall be retained, protected, and supplemented wherever possible. Exposure of soil areas shall be limited to the immediate area required for construction operations. • Grading areas shall be clearly marked and no equipment or vehicles shall disturb drainages outside of the grading area. • Use barriers to contain runoff around excavation sites. • If unreported contaminated soil is encountered during excavation, appropriate remediation of soils shall be carried out in contained areas or covered areas, or remediated through treatment prior to initiating excavation. • Filter runoff on-site using hay bales, silt fences and other appropriate control measures. • Install temporary (or permanent) storm water retention or detention structures in which treatment can occur. • No stockpiling of excavated soil or other materials shall occur in drainage channels. No excavated soil or other material shall be disposed of in drainage channels, but shall be hauled away for proper disposal. Care shall be taken to ensure that pollutant spills do not occur in drainage channels. SUB-12 Conditions of Approval • Use tarps to cover any excavation soils storage during the October-April rainy period. (EIR Mitigation Measure H:lc) 23.
