Document Description
TRLIA is proposing to improve the Reclamation District 784 urban levee system to provide 500-year flood protection to southwest Yuba County. The project would reduce flood risk, ensure the system is adaptable to climate change, and address differing flood protection levels resulting from incremental construction and improvement of the system. Project components include improving 10 miles of existing levees south of the Yuba River, east of the Feather River, north of the Bear River, west of the Western Pacific Interceptor Canal (WPIC) and southeast of the Olivehurst Detention Basin. Approximately 3 miles of new levee would be constructed on the west edge of the Yuba Goldfields and to extend the WPIC West Levee to the north.
