Napa River Rutherford Restoration Project

Horizon Water and Environment (Horizon) is supporting the Napa County Flood Control and Water Conservation District and project partner Philip Williams and Associates (PWA) on this important 5 mile river and floodplain restoration project that also protects agricultural lands.  Restoration activities include setting back levees, stabilizing streambanks, removing invasive plants, and installing instream features such as woody debris, river benches, and gravel bars to improve fish spawning and refugia habitat.  Horizon is leading the permitting process including coordinating with the U.S. Army Corps of Engineers, U.S. Fish and Wildlife Service, National Marine Fisheries Service, California Department of Fish and Game and the San Francisco Bay Regional Water Quality Control Board to gain project approvals.

In 2010 Horizon successfully obtained all necessary permits and agency approvals for Reach 3, which was constructed later that summer according to schedule.  Horizon secured permits for Reach 4 for summer 2011 construction, also keeping to the project schedule.  Horizon’s primary technical role was to translate key geomorphic, habitat, and construction concerns from regulators to the design team to revise the designs to gain approvals.  Horizon’s important procedural role was to keep all the regulatory agencies well coordinated to ensure that project approvals occurred in support of the District’s tight construction schedule.
