California Department of Fish and Game U.S. Fish and Wildlife Service Chapter 2. Alternatives Ranch to the west and the grazed parcel to the east. The roadway would have the same surface dimensions as the Reclamation Road extension. This extended access road would provide signalized access to the Refuge headquarters, as visitors would use the lighted intersection at Lakeville Road and Highway 37, travel on Reclamation Road and its extension, and then enter the Refuge headquarters from a southern access gate. A low berm (+3 feet NAVD), approximately 1,600 feet in length, would also be constructed along Reclamation Road to prevent flooding of the roadwayHighway 37 during high water or flooding events. The berm (comprised of the berm along Reclamation Road, and the maintenance road extending to the pump stations) would have a top elevation that is equal to or lower than the lowest elevation of Highway 37 within the project boundary. The top elevation will be equal to the 100-year flood elevation plus 1 foot of freeboard. Construction of this berm would require an estimated 10,300 CY of material. Soil to construct this berm would be generated by other excavations for the project and would be delivered by off-road truck or scraper. The SLT may close two of the three existing private rail crossing and, with approval of the California Public Utilities Commission (CPUC), make the remaining rail crossing into a public rail crossing. SMART may also convey two parcels (approximately 1.86) acres to SLT. Utility Relocation As discussed in the previous section, the existing above-ground utility infrastructure south of the SMART line would need to be relocated so as not to impede tidal restoration of that area. The project proposes a new route that would either run parallel to the SMART line or to Highway 37, then along Tolay Creek to Tubbs Island. New poles would be located along the north side of the railroad tracks to provide power to the vineyard to the east of Sears Point. PG&E typically removes and/or improves any poles and lines they own. Pole relocation work within the project area would likely require two or three trucks and a crew of 6, and wcould take one week or less to complete. Bay Trail System Trail Segments The discussion of proposed trail segments under this alternative is based on information presented in the Final Bay Trail Feasibility Study, prepared for the Project by Questa Engineering in December 2008 (Questa 2008). As part of the restoration effort, SLT would attempt to partially bridge the gap between two disconnected segments of the San Francisco Bay Trail by constructing one or more trail alignments across the Sears Point property, as well as provide additional trails on the property. A total of if funding allows. Up to five trail segments are proposed for the project. The design features of each segment are Sears Point Wetland and Watershed Restoration Project Final Environmental Impact Report/Environmental Impact Statement 2-25 April 2012
California Department of Fish and Game U.S. Fish and Wildlife Service Chapter 2. Alternatives summarized in Table 2-43, and proposed trail routes are shown in Figure 2-10a and 2-10c. Segment 1 is the only segment that has been proposed and adopted as part of ABAG’s Bay Trail Plan. All other segments are optional alternate alignments that are not part of the Bay Trail Plan or the Sonoma County Parks Sonoma Bay Trail Corridor Plan. Segments 1 and 5/5a would be prioritized based on funding during construction. A graded earthen pad adjacent on the north side of the rail line would provide parking for visitors utilizing Segment 1. The parking area would be located in the vicinity of the public crossing, and would provide a firm and stable surface and designated parking spaces consistent with ADA requirements. The exact location has not been determined. The total number of parking spaces would not exceed 15. Table 2-43.
