napa1Client: City of St. Helena

Waterways staff worked with the City of St. Helena and a team of consultants to design, permit, and construct a multi-objective flood control project that provides 100-year flood protection for residential properties along the Napa River, restores important floodplain and aquatic habitat, and improves public access.  Specific elements of the project include a geomorphically-based floodplain terrace, shoreline restoration involving removal of an existing gabion and rip-rap bank protection structures and replacement with a natural point bar shoreline configuration, bioengineered bank stabilization structures, FEMA certified levee setbacks and floodwall construction, relocation of homes from the floodplain, and approximately 2,500 ft of pedestrian trails with interpretive signage.
