- Tennessee Valley/Manzanita Connector Trail Project – Marin County (First Review)
The Design Review Board will hold a public hearing on a proposal by the Marin County Department of Public Works to upgrade and widen the existing 0.65-mile Tennessee Valley Trail that runs from Marin Avenue, along Tennessee Valley Road to the Mill Valley-Sausalito multi-use pathway. A portion of the project is within the Bay and shoreline band. The proposed project would involve removing the existing trail from Coyote Creek Marsh and reconstructing a portion of it in an upland area adjacent to the marsh and reconstructing another portion of it within the marsh on an eight-foot-wide, pile-supported boardwalk. In addition, the project includes constructing a new connector path between the Tennessee Valley Pathway and Highway 1, near the entrance to the Holiday Inn/Frantoio Restaurant parking lot. Further, a new pre-fabricated pedestrian/bicycle bridge is proposed across Coyote Creek and a new crosswalk and traffic signal would be installed to the south of the Highway One Bridge across Coyote Creek to allow the public to cross the highway safely instead of having to pass underneath the bridge. The project would result in approximately 7,450 square feet of new pile-supported fill in the Bay needed to construct the elevated boardwalk through Coyote Creek Marsh. The U.S. Army Corps of Engineers has initiated informal consultation with both the U.S. Fish and Wildlife Service (FWS) and the National Marine Fisheries Service to evaluate whether the proposed trail and boardwalk would have any adverse impacts on a number of state and federally-listed species that may potentially occur with the project area. Initial discussions between the applicant and the FWS indicate that the salt marsh harvest mouse may be the only species that is potentially vulnerable to impacts from the trail project. The Board’s review of this project will focus on: (1) whether the design of the project is consistent with the Commission’s laws and policies concerning Bay fill; (2) whether the public access is sited and designed to be compatible with wildlife utilizing the project site; (3) whether the project provides adequate, usable and attractive public access improvements; and (4) whether the project is sited and designed to be resilient to the potential impacts of sea level rise.

- Dumbarton Bridge Seismic Retrofit Project. (First Review)
The Design Review Board will hold a public hearing regarding a proposal by the California Department of Transportation (Caltrans) to seismically retrofit the Dumbarton Bridge in the City of Menlo Park in San Mateo County, and the City of Fremont in Alameda County. Caltrans proposes to strengthen the existing bridge’s substructure by adding concrete bolster along the pier footings, columns and bent caps of the main channel crossing and the two approach sections of the bridge. The project would also include reinforcing the two trestle sections of the bridge to add lateral strength. In addition, Caltrans proposes to replace all 44 deck joints on the bridge. The project will require use of temporary trestles to accommodate construction vehicles and equipment. While the temporary trestles are in place, retrofit work would be conducted on the superstructure (roadway bed) and substructure (under-deck structure sections) of the various bridge sections, including: (1) retrofit of the bridge hinges located within the superstructure; (2) strengthening of the pile caps, columns, pedestals and bent caps; and (3) other related work. Reinforcing the connection between the columns, pedestals, and pile caps would involve adding a reinforced concrete collar. The reinforcement would increase the size of the pedestals as they sit atop the pile caps. In addition, the project involves the construction of a concrete tidal barrier along the shoreline to keep Bay water from encroaching onto the north frontage road at the western approach to the bridge. Proposed public access improvements would include replacing the bridge railings along the existing bike/pedestrian path and creating a new public viewing area on the south side of the western approach to the bridge.
