Our solution included the removal of an existing concrete ford crossing and replacement with a pedestrian and light access vehicle bridge and restored channel configuration. The design improved adult and juvenile steelhead passage and habitat through creation of a natural step-pool morphology, woody debris cover and pool habitat. Pool habitat was identified as a limiting factor to fish production in this important tributary to Coyote Creek Specific project tasks included flood frequency analysis, hydraulic modeling and design, topographic mapping, construction plans and contract documents, and regulatory compliance (CDFG/USFWS/RWQCB/CEQA).
Quail Hollow Bridge Replacement and Channel Restoration
Client: City of San Jose
Waterways staff was retained to assess existing conditions and provide recommendations for enhancement of riparian and aquatic habitat along 2.5 miles of stream channel within Alum Rock Park, in the City of San Jose. The assessment identified Quail Hollow as a high priority project site based on fish passage impediments, stream channel erosion, and recreational access concerns.
