Mitigation Monitoring and Reposing Program B. Infrastructure Systems: Drainage Page I S INFRASTRUCTURE SYSTEMS: DRAINAGE Mitigation Measure: 84b. Set back development sufficiently to accommodate a Bow of 27,000 cfs (with WSEL of 316 feet as illustrated in DF.IR Figure ~ in a channel widened to the east only; if Zone 7 adopts a Master Plan for regional flood control prior to the submittal of the project grading plan, adjust setback consistent with that plan. Impact to be Mitigated: Development of the project could conflict with implementation of Zone 7 regional flood control plans for the Arroyo de la Laguna south of [he Ber- nal Avenue bridge. Ageocy/individual Responsible for Implementation: Site and project developer(s) Implementation Timing: Prior [o and during grading of the West Pazcel. Mitigation Speciflcatioos: The August, 2000 Specific Plan project provides a setback from the main channel of [he Arroyo de la Laguna of approximately 300 fee[ from the [op of the eastern bank as part of the Phase 1 development Such a setback leaves open a wide range of in-channel flood control improvement options for Zone 7, which has recently revised its estimated future 100-year Dow from 27,000 cfs to 25,500 cfs. This setback requirement is incorporated in the August, 2000 Specific Plan. Phase it compatibility with implementation of regional flood control plans will be evaluated in conjunction with the Yhase Il Ylan. Agency/Individual Responsible for Monitoring: City of Pleasanton, Planning Department and Public Works Department Action by Monitor: Verify setback in the adopted Phase I Plan. Monitoring Timing: Prior [o approval of tentative map and site grading plan; upon completion of grading Monitor: Completion Date: Signature:
