(The SRVRPC also reinforced the County Planning Commission' s position that the park/school site should be initially offered for use as a school site as opposed to an exclusive park site. ) BACKGROUND The Board initially heard the recommendations of both the County Planning Commission and San Ramon Valley Regional Planning Commission on this project at the Board' s April 8, 1997 meeting. After taking testimony, the Board continued the hearing to this date . RECOMMENDED MODIFICATION TO CEQA FINDINGS At the last hearing, the East Bay Municipal Utility District expressed concern about proposed findings that had been prepared relative to this project ' s compliance with the California Environmental Quality Act (CEQA) . Following the last meeting, there has been additional discussions among the interested parties . Staff is recommending that the CEQA -2- The Meadows Kaufman & Broad(A) findings be modified to include the amended language identified below: Section 1: Findings Concerning Significant Impacts C. PUBLIC SERVICES AND UTILITIES; IMPACT C. 1 : "Findin : Mitigation Measures Feasible and Required to the Extent Permitted by Jurisdiction. The Board finds that (a) Mitigation Measures C. 1 (a) , (b) and (c) reduction technicques are not within the responsibility or jurisdiction of Contra Costa County but are within the responsibility and are under the jurisdiction of East Bay Municipal Utility District (EBMUD) could and should be EBMUD ed b E adopted :<. ��r........ ...... ::<:>" a : . . ::::::::.::.;':..... . .......:::::::::.

Q.n..:::..�e�.�.. .......:....... ...:s.::::: The applicant and EBMUD concur with this modification to the CEQA findings . ALTERNATIVE SITE PLAN MAP Attached is an alternative (118-Ac School") site plan dated April 8, 1997 submitted by the applicant on the project . • The site plan is similar to the one recommended by the two Planning Commissions . The primary change is to expand the park/school site to 8 acres, as had been suggested (but not required) by both Commissions. This has been accomplished by removing a tier of residential lots immediately south of the school . 0 The applicant recovered some but not all of the lots lost to the expanded park/school site elsewhere in the project . The number of lots is now reduced from 195 lots to 192 lots . The reconfiguration has been accomplished with a reduction in the curvilinear form from the previous site plan and a "tighter" lotting pattern. • The alternative site plan does not provide for the off-street path connector between Street A and and Court G recommended by the Commissions . • In staff ' s judgement, the modifications do not introduce any new significant impacts that have not already been adequately addressed in the Environmental Impact Report prepared for this project . Staff has forwarded copies of the alternative site plan to the Commissioners on each Planning Commission, the School District and the Town of Danville . -3- The Meadows Kaufman &Broad(A) Modified Conditions to Accommodate the Alternative Site Plan If the Board is inclined to base an approval of the preliminary development plan on the April 8, 1997 Alternative Site Plan, then the conditions of approval should be modified as indicated below.

Dennis Barry, Community Development Department, presented the staff s recommendations and modifications to the previous plans. He noted the seven (7) acre park/school site has been increased to eight (8) acres, which reduced the project from 195 to 192 planned units and thus modified the plan. Further, he stated that the East Bay Municipal Utility District (EBMUD) representatives and the applicants agreed to modify the findings language with regard to water issues (Page 3, Section 1). Mr. Barry further stated that the County Planning Commission recommended there be an off-street path connector added between Street A and Court G, and that the applicant disagrees with this addition on the theory that the path connectors can become attractive nuisances. Heather Ballenger, Public Works Department, presented modifications to the conditions of approval as suggested by the Public Works' staff. The following persons presented testimony: John Bayless, applicant, Kaufinan & Broad of Northern California; Greg Miller, Civil Engineer for the applicants, Carlson, Barbee & Gibson, Inc.; Bill Fallah, Esq., Attorney for Kaufinan & Broad of Northern California; Wayne Tooker, 1641 Lawrence Road, Danville; Jim Blickenstaff, Sierra Club, 2410 Talavera, San Ramon,; Linda Lemon, Save Our Diablo Creeks, 572 Zenith Ridge, Danville; Nancy Beaton, 1631 Lawrence Road, Danville; Lettie Siu, 1465 Lawrence Road, Danville; Tom McDaniel, 1253 Lawrence Road, Danville. John Bayless, applicant, Kaufinan & Broad of Northern California spoke in rebuttal: Greg Miller, Civil engineer for the applicants, spoke in rebuttal. All persons desiring to speak having been heard, the Board discussed the issues. Supervisor Canciamilla moved that the public hearing be closed, and that the Board adopt recommendation Option A with the revised conditions as stated today, that the modified CEQA condition contained on Page 3 also be adopted, that the alternative site plan on page 4, (reducing the number of units and 1 providing for the 8 acre park/school site) be adopted, and instructed that as a condition, the payment of $40,000 be made towards the affordable housing study. Supervisor Rogers seconded the motion and commented on the positive role that the San Ramon Valley Planning Commission has taken in the Tassajara area development. Supervisor Uilkema remarked that concern for appropriate infrastructure in the area had been met with this development. Chairman DeSaulnier advised that he felt the mitigation for the proposed park/school site made this project worthy of support. IT IS BY THE BOARD ORDERED that the public hearing is CLOSED; Option A of staffs recommendations is APPROVED including: Tassajara Meadows' Final Environmental Impact Report is CERTIFIED as adequate and complete; Resolution No. 97\222, determining to amend the County General Plan (County File #GP 0009-95) is ADOPTED, to be included in the next consolidated General Plan Amendment; Rezoning application (County File #RZ 3036-95) is APPROVED; Ordinance 97-9 is INTRODUCED, giving effect to the rezoning, Reading is WAIVED, and May 13, 1997, is SET for adoption of same; the Preliminary Development Plan is APPROVED, with the Findings and Conditions (See attached Exhibit I ); the Mitigation Monitoring Program is ADOPTED; and staff is DIRECTED to post a Notice of Determination with the County Clerk. 2 A.

We are property owners residing at 1641 Lawrence Road and Tassajara Meadows will have a major impact on our quiet rural community on Lawrence Road. We,along with many of our neighbors,wish to go on the record with the following concerns. Since,the Tuesday 3:00 PM meeting time is extremely inconvenient for most daytime workers,we may have our neighbor,Don Beaton,submit this letter on our behalf. 1. Improper notification of the Board of Supervisors meeting which included Tassajara Meadows on the agenda We were not given written notification of the May 6 3PM meeting and this is an ongoing problem with the county and the developers. It is unseemly that the Board tolerates such negligence in light of the matters that will be discussed. 2. Risk of pollution and erosion from the drainage of Tassajara Meadows through Alamo Creek Alamo Creek cuts through the center of our three acre parcel of land. As the creek winds down the valley its channel becomes deeper and the banks become steeper. It is a haven for native plants and a sanctuary for many wild animals. Since Tassajara Meadows drains through Alamo Creek,the influx of water will seriously damage our fragile creek banks and even the foundation of our home which sits 40 feet from the bank. Pollutants will harm wildlife including some endangered species such as the red-wing blackbird and kit fox which reside in the area surrounding the creek. 3. Lack of emergency escape routes In the case of a wild fire,flood or any other natural disaster,residents on Lawrence Road have no emergency escape routes. Everyone will have to make his or her way out through Tassajara Meadows. .This could create a huge disaster, since all residents of Lawrence Road will have to wait for the residents of Tassajara Meadows to evacuate first. If a major fire is raging up the valley;many Lawrence Road residents could be killed while a huge bottleneck of over 200 households forms at Camino Tassajara. 4. Traffic The infrastructure to handle the increased traffic,pollution,and noise will not be in place. We and our neighbors request detailed answers to the concerns listed above. We love our homes and the quaint neighborhood on Lawrence Road. It is a special place. We must retain it. It will stand as a reminder to future generations of what made Contra Costa special in the beginning when there were native creeks,plants,and wildlife in abundance; before the valley becomes a maze of cookiecutter homes;before we savagely destroyed nature. We await your response. Sincerely, Lois Tooker cc: Arma Estrada,Attorney at Law Request to Speak Form ( THREE (3) MINUTE LIMIT) D 411i� .

Mr. Mark.DeSaulnier Board of Supervisor Contra Costa County 651 Pine Street Martinez, CA 94553 Subject: Comments on Tassajara Meadows General Plain Amendment and Related Actions Dear Mr. DeSaulnier: The final EIR documented the development of 230 homes. 1.t came to my attention that the proposed land use for this project has been changed to include about 1.90 homes and a 7-acre park/school site. This is a signircantchange in the proposed project land use compared to that documented in the Final E.M. This change in land use will have sign!flcant impacts on traffic volumes, traffic operation., safety, access and internal circulation. Since none of these impacts were addressed in the context of the proposed park/school site, the Final EIR did not address nor mitigate these impacts. As a registered Traffic Engineer, I am very familiar with traffic and safety issues related to school sites. The rnaximum capacity of a public school is typically 600 students. Within the San Ramon Valley (SRV) Unified School District,existing enrollment at individual school site varies from 300 to 800 students. The SRV School District currently offers limited school bus service to those who pay an annual fee. Currently, about 35 of the 18,000 students in the SRV School District use the school bus service. It is reasonable to assume that the SRV School District will provide similarly limited school bus service to the proposed school site. Relatively few students will access the school site by public transit. Therefore, the vast majority(90 to 95%) of the students will be dropped off and picked up by parents/adults who drive. The proposed school will generate roughly 890 vehicle trips(450 enter, 400 exit)just before school(7:30-8:30 am) and roughly 650 vehicle trips (300 enter, 350 exit)just after school (2:00-3:00 pm.). Hence, the volume of peak hour traffic generated by the school site alone is several times that generated by the 230 homes combined. (According to the Final )✓M 230 homes will generate 200 trips in the A.M.peak hour and 150 trips in the PM peak hour.) These peak hour traffic generation estimates already account for vehicle trips made by employees and visitors. The large volume of vehicles entering and exiting the proposed school site will result in traffic congestion, vehicle queuing,vehicular conflicts acid safety hazards. Some of the students who walk or bike to the proposed school site will be required to cross Camino Tassajara. Camino Tassajara is currently a two-lane road and will ultimately be widened to a six-lane arterial street. The crossing of six travel lanes will be a safety hazards for pedestrians(and especially for juveniles) even at signalized intersections. Other potential problems at the school site are overflow parking onto neighboring residential streets during special events.

Lawrence Road currently provides access to 60+ homes. According to the Lawrence Road-Leema Roars Specific Plan, Lawrence Road will ultimately provide access to 170+homes. It is for the many reasons stated-above that the Final EIR is grossly inadequate and should not be voted by the Board at this.time. Thank you.

CONTRA COSTA BOARD OF SUPERVISORS RECEM MAY - 61997 May 6, 1997 CLLmw BOARo OF SU,A RVEM To All Board Members Regarding: Tassajara Meadows We are filing this letter with the Contra Costa Board of Supervisors to let our concerns be know regarding the impact of the Tassajara Meadows Project to the residence of Lawrence Rd. We reside at 1631 Lawrence Rd., and have many concerns with the growth that is being allowed to develop in this area. 1. Alamo Creek runs through our property, and we have serious concerns that the added water run off from the future development up stream, could cause damage to our property, and the environment. 2. County Statute 914-4.004 states analysis of water flow should take place before any urban run off takes place. As of this date, no one to our knowledge has reviewed Alamo Creek and its effects on our property, and the other property owners on Lawrence Rd. 3. We are also concerned that any change in the realignment of Lawrence Rd., would have an adverse effect in the traffic patterns that now exist. Will the new homeowners be informed by the developer, that in order to service Lawrence Rd. residence, there will be numerous Commercial Vehicles that would be required to travel through their development, such as propane trucks, feed supplies, horse trailers, etc.? This does not seem to be a safe plan considering that there will be children playing in the streets. We feel it is imperative that Lawrence Rd. stays open to Tassajara in order to service the needs of the existing residence. We hope the Board of Supervisors will look at all aspects of this project and all future projects with regards to it effect on the local environment. As existing property owners on Lawrence Rd., we want to go on record as to these concerns. We also feel that by scheduling these meetings at 3:00 p.m. in the afternoon, on a week day, that your are hoping the residence will not be able to voice their concerns. Thank you for your attention to this matter. Donald and Nancy Beaton 1631 Lawrence Rd.

The development of 350 homes currently under construction along Lawrence Road and the 190 homes proposed on Tassajara Meadows will greatly impact water quantity and quality. The impervious surface run-off will prevent recharge ground water thus affecting well water quantity. Urban run-off inadequately treated will affect well water quality. It is documented in the Wendt EIR and TVPOA DEIR that the water at the South end of Lawrence Road is of drinking water quality. This project must show proper mitigations for water quality to keep the water in Alamo Creek as clean if not cleaner than it is now. This EIR does not show that. Conditions of Approval#43-45 and 48 are vague and non-specific. Mitigations are required now so that the public can review the proposal. COA are not mitigations and are not subject to the same scrutiny by the public and performance standards. Condition of Approval#49 is vague. If scenario A with on-site detention basin is used,then a hydrology study must be done on Mr. Don Beaton and Mr. Wayne Tooker's properties at the end of Lawrence Road. Hydrology studies by an independent hydrologist of the property owners' choice must be required of the applicant and paid for by the applicant as the impact of this project remains significant to cause creek bank instability and erosion with the real possibility of damaging Mr. Tooker's home. County Ordinance 914-4 and 914-6 has not been met by this EIR. If scenario B with off-site TVPOA detention basin is used, then the water quality and quantity issues along West Branch of Alamo Creek must be addressed as it will significantly impact Simpson Lake and Wildlife Reserve which is located on my property. An independent hydrology study of the creek bank and levee stability must be made and paid for by the applicant as Simpson Lake will be greatly damaged by this project and the cumulative impact of Wendt Project and TVPOA. Scenario B implies that this lead agency is growth inducing as the detention basin on TVPOA does not now exist and TVPOA has not yet been approved. Scenario C assumes Town of Danville has properly mitigated for the significant and cumulative impact on Mr. Beaton and Mr. Tooker's properties--Town of Danville'has not. If applicant chooses Scenario C,the impact of this project will jeopardize Alamo Creek bank stability and create a health and safety hazard for Mr. Tooker and his family. Page 1 of 2 Save Our Danville Creeks Condition of Approval#52 on-site detention basin must be required and is not an option for the applicant . Other developments in the surrounding areas --Blackhawk, Shadow Creek, and Bettencourt were required to have on-site detention basins. Detention basins are a necessity ,they are not optional. All mitigations must be on-site and if not on-site, then the applicant must fully explain why on-site mitigations are not possible. This EIR does not meet this CEQA requirement. No mitigations are provided for post-construction water quality thus violating the Clean Water Act-- no detention basin, no grassy swales, no biofilter--to assure clean water flowing into Alamo Creek. See attached newspaper article documenting urban pollutants impacting creek water. For the record, this;A;Vviolated the Better Government Ordinance by limiting the public access to information on this project for the February 11, 1997 meeting when the project was on the agenda before the Planning Commissioners. As a resident on Lawrence Road, I will state that I was not notified of this meeting or the previous Board of Supervisors meeting regarding this project.. There are too many unanswered questions to approve this project at this time. I urge you to vote no.

Applicant shall reduce post-development flows to predicted pre-development flow levels at the County line. The project shall under no circumstances result in a peak flow rate in Alamo Creek at the County line greater than the flow restriction of 132.3 cubic meters per second (4670 efs), when considering ultimate development of the watershed. This flow limit was agreed upon by Alameda and Contra Costa Counties. The applicant shall mitigate this project's increase in peak flow rates within Alamo Creek by implementing one of the following measures: A. Constructing an on-site detention basin at the down gradient end of the project site to reduce post-development flows to predicted pre-development flow levels at the downstream project boundary and at the County line. The preliminary design of the basin shall be based on results from hydrology modeling which utilizes the CCCFC&WCD model or other hydrology modeling which meets the approval of CCCFC&WCD, OR, B. Prior to filing the first Final Map, obtain agreements and coordinate with other developments within.the Alamo Creek watershed to increase the size and capacity of off-site detention basin(s), as necessary, to reduce this project's post- development flows to predicted pre-development flow levels at the County line.

OR, C. Project storm water shall drain to the southern end of the project and discharge into the Lawrence Road drainage system that runs south down Lawrence Road and discharges into Alamo Creek. Increased storm water run-off from this project and other development in the Lawrence Road area that will be served by this drainage system will be mitigated by detention facilities downstream of the Lawrence Road area. Applicant shall form a benefit assessment district or annex into an existing benefit assessment district to collect revenue for this projects fair share cost of maintaining the downstream storm water detention facilities. (EIR Mitigation Measure I.2a) 50. Prior to the issuance of a Grading Permit(s), applicant shall obtain all drainage related permits (County Drainage Permit, Fish and Game Permit, Army Corps Permit, Regional Water Quality Control Board Permit), as required. 51. Applicant shall retain a licensed geotechnical engineer to perform a study which analyzes slope stability, allowable creek velocity, and erosion potential for Alamo Creek, downstream of the project, where peak runoff and runoff volume has increased due to the project. 52. If an on-site detention basin is constructed, the applicant will be required to comply with the following. If an on-site basin is not constructed, this condition of approval shall be waived. A. Prior to filing the first Final Map, applicant shall submit a revised site plan which provides for an on-site detention basin of adequate volume. Access and maintenance roads shall also be shown. The revised site plan shall be subject to the review of Public Works and the review and approval of the Zoning Administrator. B. Design of the detention basin shall be submitted to the Alameda County Flood Control District for review and comment andAo the CCCFC&WCD for review and approval.

Under the terms of the agreement, Kaufman & Broad will dedicate eight acres to the district for use. as a school site. This dedication will be in lieu of both statutory and supplementary fees. In addition, this site will be fully improved including preliminary grading, Camino Tassajara frontage improvements, the realignment of Lawrence Road, curbs and gutters, sidewalks, two driveway cuts, frontage landscaping, and all utility services stubbed out to the site. The district is very pleased with this agreement which provides full school mitigation and provides us with a needed school site in this area of continued growth. Your consideration of the District's input throughout this process has been appreciated. Sincerely, Joan 1.
