Project Construction Schedule

The Napa River/Napa Creek Flood Protection Project includes improvements to six miles of the Napa River from Highway 29 at the Butler Bridge/Southern Crossing to near Trancas Street, and Napa Creek from its outfall to the Napa River for about one mile upstream.  Elements of the Napa Project include bank terracing, bridge replacements, bypass channels, culverts, floodwalls, and levees.  

A number of Project components have been completed, such as the 600 plus acres of restored wetlands in the South Wetlands Opportunity Area, the replacement of the Third Street, First Street and Maxwell Bridges, the construction of the new Soscol Avenue Bridge, the cleanup of contaminated properties in the Oil Company Road area, the east bank terracing, and the Hatt to First Floodwall and Promenade, including the renovation of Veterans Memorial Park.  The remaining components that are currently under construction or yet to begin are listed below.  As of 2014 the Napa County Flood Control and Water Conservation District (NCFCWCD) is reanalyzing remaining project elements to more effectively compete for Federal funding and determine priorities moving forward.
