Document Description
The California Department of Fish and Wildlife (CDFW) has executed Lake and Streambed Alteration Agreement (EPIMS- SCL-50335-R3), pursuant to Fish and Game Code section 1602, to the project Applicant, Lani Ho/Santa Clara Valley Transportation Authority.
The project is limited to the installation of features of the new interchange over and in Gavilan Creek. The Phase 1 Project consists of the following improvements: 1) Construction of new US 101/SR 25 interchange on-and offramps. The US 101 southbound off-ramp will begin south of Castro Valley Road and will consist of a bridge extending over Gavilan Creek such that it will not require an extension of the existing Gavilan Creek culvert. The bridge over Gavilan Creek will accommodate flood flows for the Phase 1 Project and the US 101 Improvement Project, while also minimizing impacts to Gavilan Creek, 2) Construction of biofiltration swales to treat runoff from the roadway, with use of erosion control blankets where the swales outfall into Gavilan Creek.
