Document Description
he County of Alameda (Lead Agency) proposes to construct a six-mile, Class 1, multi-use trail for pedestrians, bicyclists, and equestrians between the unincorporated community of Sunol and Niles District of the City of Fremont, both in Alameda County. In addition, the project would provide a critical link to Palomares Road bypassing State Route 84 (SR-84) and would expand the Alameda Creek Trail, which provides a direct connection to the 500-mile San Francisco Bay Trail. The proposed trail would consist of a 10-foot wide, all-weather surface with 2-foot shoulders on either side composed of decomposed granite. The trail would meet accessibility guidelines, and include different barrier options to separate trail users from railroad and highway traffic. In addition, retaining walls would need to be installed in some locations to accommodate slope cuts. These walls would be sculpted concrete with soil nail tiebacks. The project would include provisions of staging areas with sufficient parking to avoid impacts to surrounding neighborhoods from visitors’ vehicles. Staging areas would be created at both Niles and Sunol, as well as Palomares Road. In addition, existing staging areas associated with the Alameda Creek Trail could support the need for parking. The project would be implemented in three phases.
