the creation of mitigation features. A field visit with USAGE staff to verify the delineation is included. Task 4. Final Wetland and Riparian Mitigation Plan, Mission Creek A final wetland and riparian mitigation plan will be prepared to describe the creation of 1.0 acre of perennial wetland habitat and creation/restoration of approximately 1.2 acres of riparian habitat surrounding the Mission Creek wetland. The final wetland and riparian mitigation plan will be based on the conceptual plan submitted to the USAGE, CDFG and the RWQCB in June 2007, but will describe the creation of additional low-lying areas surrounding the wetland in which riparian habitat will be created. We will review additional ground-water monitoring data collected by the City and/or Zone 7 Water Agency to evaluate ambient water table conditions. The plan will describe habitat types and areas created to mitigate for the Bernal Bridge project, as well as the excess wetland acreage that will be used to mitigate for a future City of Pleasanton project. The plan will be prepared in a format suitable for presentation to the agencies, and will describe mitigation site creation, soils, hydrology, site preparation, planting and seeding, maintenance, monitoring and reporting, and performance standards. Following approval by the City, this plan will be submitted to the USAGE, RWQCB, CDFG and USFWS. Implementation of the mitigation plan by the City will become a condition of the permits. We have assumed that we will receive aerial photos, hydrologic information and other pertinent information required for the hydrologic analysis from Zone 7 and City of Pleasanton. Task 5. Final Wetland and Riparian Restoration Plan, Arroyo del Valle at Bernal Bridge A final wetland and riparian restoration plan will be prepared to describe the restoration of riparian and wetland habitat that will be temporarily disturbed during construction of the bridge. We propose to create a separate document for this element of mitigation to provide clarity about the type, area and location of mitigation plantings at Arroyo del Valle as opposed to plantings at the Mission Creek site that mitigate for permanent impacts of the Bernal Bridge, and impacts related to the future City project. The plan will be similar in format and content to the Mission Creek plan, but will be restricted to riparian plantings on the banks of the creek and the salvage, storage and planting of emergent vegetation in the creek. It will also describe the removal of the existing rock riprap beneath the bridge, as discussed with Brian Wines of the RWQCB during the 2006 site visit. The plan will describe mitigation goals, design and implementation, maintenance, monitoring, reporting and performance standards. Following approval by the City, this plan will be submitted to the USAGE, RWQCB, CDFG and USFWS. Implementation of the mitigation plan wilt become a condition of the permits. Task 6. Hydraulic Modeling To aid in design of the diversion structure on Mission Creek, and to evaluate potential tail-water (downstream) conditions at the wetland outfall, Balance will update HEC-RAS models that were developed for Mission Creek and the Fairgrounds Channel conceptual plan. We will model existing conditions based on the initial survey and as-built topographic map provided by the City of Pleasanton/proposal7rev2
