Napa River/Napa Creek Flood Protection Project

Passed by two-thirds of Napa County voters in 1998, the Project provides environmental restoration and economic development by incorporating the following engineered components to achieve 100-year flood protection while maintaining the living river principles:

• lowering of old dikes
• marsh plain and floodplain terraces
• Oxbow dry bypass
• Napa Creek floodplain terrace
• Upstream and downstream dry bypass culverts along Napa Creek
• new dikes, levees, and floodwalls
• bank stabilization and protection (including a grade control structure)
• pump stations and detention facilities
• bridge replacements.
