The East Bay Regional Park District (EBRPD), Tri-Valley Conservancy (TVC) and Livermore Area Recreation and Park District (LARPD) collaborated on the planning, design and construction of a new pedestrian bridge and trail connecting two regional parks: Shadow Cliffs and Del Valle Reservoir. The new trail and bridge over Arroyo Del Valle in LARPD’s Sycamore Grove Park serves pedestrians, cyclists and equestrians.
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, Wildscape identified feasible alternative alignments for a multi-use bridge crossing over Arroyo Del Valle creek. 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. During the second phase, Wildscape produced final plans, specifications, and Engineer’s estimate and supported TVC and LARPD during Contractor bidding and construction.
