Arroyo Del Valle Bridge Feasibility Study / Livermore, CA

Background

The East Bay Regional Parks District (EBRPD), Tri-Valley Conservancy (TVC) and Livermore Area Recreation and Parks District (LARPD) are collaborating on the construction of a trail connecting two regional parks: Shadow Cliffs and Del Valle Reservoir. The trail will serve bicycles and pedestrians and be accessible to the crossing at the Arroyo Del Valle in LARPD’s Sycamore Grove Regional Park.

Overall Progress

Wildscape completed a feasibility study and conceptual design for a proposed bridge across the Arroyo Del Valle in Livermore, CA that will connect two popular regional park trails. Managing a multi-disciplinary team and collaborating with stakeholders and landowners including the EBRPD, the LARPD, the City of Livermore, TVC, Zone 7 Water Agency and the USGS we identified feasible alternative alignments for a multi-use bridge crossing over Arroyo Del Valle creek and developed conceptual designs, costs, and a permitting matrix for the preferred alternative. Topographic, geologic, soils, and stream gage data were assessed along with dam operations and the FEMA regulatory floodplain in order to determine bridge height, span and structural needs, permitting requirements and associated construction costs.
