For East Bay Regional Parks District (EBRPD) and Alta Planning + Design
Pinole, California

This preliminary engineering/biological assessment study evaluated design, construction, and drainage issues along a paved, 1.7-mile, multi-use trail segment connecting the existing Bay Trail at Pt. Wilson with Pt. Pinole Regional Park to the south. The alignment for this segment parallels and is located primarily within the Union Pacific Railroad (UPRR) right-of-way. The study verified the preferred alignment, determined infrastructure and other improvements necessary to accommodate the trail, and resolved possible  conflicts between neighboring land uses, sensitive wildlife habitat, and trail users. Key elements included: 1) review and assessment of current EBRPD agreements with UPRR, 2) determination of setback and safety criteria established by UPRR, 3) determination of fencing/barrier types required to separate trail users from the active railroad envelope and adjacent wetlands, 4) identification of storm drainage requirements and tidal influence areas along the Montalvin Manor subdivision, 5) identification of potential wetlands, endangered species, and other significant environmental issues, 6) development of the preliminary engineering plan and construction cost estimate, and 7) completion of CEQA Initial Study.
