What is the Delta Levees Special Projects Program?

The Delta Levees Special Flood Control Projects Program works directly with local agencies to provide critical financial assistance for flood protection in the Delta. This funding protects and enhances the economic, environmental and cultural resources in the Delta. The Program is authorized under the California Water Code to provide funding to safeguard public benefits, including roads, utilities, urbanized areas, water quality, recreation, navigation and fish and wildlife from flood hazards. The Program mitigates the habitat impacts of each project and ensures a net long-term habitat improvement in the Delta.

When did the program start?

To ensure protection of local and state interests in the Delta, the Delta Levees Special Projects Program was established in 1988 by the California State Legislature under SB 34 and later revised under SB 1065 (1991) and AB 360 (1996). Since its inception the Program has invested approximately $300 million in the Delta for flood protection and related habitat projects. The Program was authorized originally to address flooding on the eight western Delta islands, as well as the communities of Thornton, New Hope and Walnut Grove. It was expanded in 1996 to the entire Delta and to portions of the Suisun Marsh (approximately 12 miles of levees on islands bordering the Northern Suisun Bay from Van Sickle Island westerly to Montezuma Slough), as outlined in Section 12311 of Water Code.

Who can participate in the Program?
