// Strategic Significance
The Napa River flood control project is an innovative living levee system that has dramatically reduced flood risk in downtown Napa after devastating floods in 1986 and 1995. The project used setback levees and restored floodplains instead of traditional hard levees. It is considered a national model for urban flood control using natural systems.
// Civilian Impact Assessment
Napa CA with 80,000 residents experienced repeated catastrophic downtown flooding before the project. The wine country economy worth billions depends on flood control for vineyards and the city. The 2014 South Napa earthquake complicated flood infrastructure maintenance.
