Mid-Canal Storage Project
Document Type
MND - Mitigated Negative Declaration
Received
Present Land Use
Existing federal right-of-way and canals. County GP and zoning do not apply to federal right-of-way.
Document Description
The project consists of creating a single wide channel by joining two existing parallel canal channels, one the original earthen canal constructed in the 1940s, and the second concrete-lined canal constructed in 2005 as a part of the Coachella Canal Lining Project (CCLP). All earthwork required to join the two channels and create the storage reservoir will be conducted within the existing fence lines defining boundaries of the federal right-of-way within which the parallel canals are located. The project will provide up to 728 acre-feet of water storage to alleviate water storage deficiencies and increase water storage capacity, reliability, and efficiency within the CVWD water distribution system. The project will also resolve an ongoing maintenance problem in the affected lined-canal segment caused by high-clay content that results in significant cracking of the concrete. All earthwork will be balanced on site with no material to be exported. Imported rock material will be placed on the eastern reservoir bank for erosion control. Work will be staged so that water supply deliveries are maintained throughout project development. Earthwork and related construction activities are expected to be completed in 6 to 8 months beginning in late summer 2023 and concluding in late-winter 2024.
