Document Description
The Contra Costa Water District (CCWD) is proposing construction of the Contra Costa Canal Encasement Project, which involves installing up to 3.97 miles of buried pipeline in place of the existing unlined portion of the Contra Costa Canal. The pipeline installation would occur between the trash rack near Rock Slough and Pumping Plant No. 1. Using preliminary engineering design analyses, CCWD recommends that the new pipeline be installed in the U.S. Bureau of Reclamation's 300-foot canal right-of-way (ROW). CCWD would consider constructing portions of the pipeline outside of the open waters of the canal but within the ROW, as well as adjacent to the canal ROW, if use of portions of adjacent property where CCWD would hold construction easements would improve constructability without incurring significant environmental impacts. The final pipeline alignment would be determined during the final design process.
