. Installation of an interim traffic signal at the Bernal Avenue/ Vineyard Avenue intersection, and construction of a partial roadway widening on Bernal Avenue just south of the Arroyo Del Valle. . Interim modifications to improve traffic movement at the Bernal Avenue and Vineyard Avenue intersection and on Vineyard Avenue including the installation of traffic mast arms and signal heads, installation of median curbing, and widening of Vineyard Avenue. . Sanitary sewer improvements including the installation of 18" sanitary sewer lines and appurtenant structures on Bernal Avenue through the Vineyard and Bernal Avenue intersection in advance of repaving the roadway intersection. . Acquisition of mitigation credits ($7,000) for the preservation of Red - legged Frog habitat from Ohlone Preserve Conservation Bank. DISCUSSION Mitigation for wetland and riparian habitat was accomplished both on -site and off -site in accordance with the environmental permit requirements (Nationwide 401 Permit). The on -site mitigation area is located in the Arroyo Del Valle adjacent to the bridge, while the off -site mitigation area is located at the southeast corner of Valley Avenue and Laguna Creek Lane, adjacent to Mission Creek on the Bernal Property. The use of the Bernal property for wetland and riparian mitigation complied with the Bernal Property Specific Plan, which designated this area as agricultural. Per the Specific Plan, agricultural uses were anticipated to provide "hands -on" lessons in the natural sciences and ecology and to provide for a living classroom experience. An observation deck will be evaluated and installed at a later date to foster these learning activities as stated in the Specific Plan. Therefore staff recommends that $100,000 to be reserved under the project account for this anticipated project. Long- term monitoring to assess the performance of the wetland and riparian mitigation effort will be conducted for a total of five years to ensure performance standards have been met and that United States Army Corps of Engineers (USAGE), Regional Water Quality Control Board (RWQCB) and California Department of Fish and Games (CDFG) mitigation requirements have been fulfilled. The mitigation monitoring effort includes site monitoring, habitat monitoring, hydrologic monitoring, and annual reporting. On March 16, 2010, the City Council approved a contract amendment with Mosaic Associates for a not -to- exceed amount of $115,194 to provide the required monitoring and reporting services. Performance of mitigation sites for the next 4 years or until accepted by the regulatory agencies is unpredictable and may require correction /adjustment. Therefore, staff recommends that the remaining balance of the project account to be remained to cover both the initial contract amount with Mosaic as well as any additional remedial measures necessary as a result of the monitoring efforts. The Department of Parks & Community Services has accepted both mitigation sites as part of the Parks Division's on -going maintenance routine of planted areas. Page 3 of 4
