The Three Rivers Levee Improvement Authority is proposing to implement improvements to the Reclamation District 784 levee system to provide 500-year flood protection to southwest Yuba County. Based on the preliminary review, levee improvements may be necessary along a total of up to approximately 11 miles of existing levee segments located on the north side of the Bear River, west side of the Western pacific Interceptor Canal, and south side of the Yuba River. Existing embankments in the western portion of the Yuba Goldfields also may be modified and extended.
