Authorize the Mayor, or designee, to sign a letter in support of Contra Costa Water District’s request for federal funding for the Contra Costa Canal Emergency Flood Control Project authorized in the Water Resources Development Act (“WRDA”) of 2007.
Rock Slough, which terminates in Oakley, is the main channel where the Contra Costa Water District (“CCWD”) obtains water from the Delta for its main canal to service its approximately 550,000 customers. The City of Brentwood (“City”) utilizes this slough as well as the CCWD main canal to convey its surface water purchased from the East Contra Costa Irrigation District (“ECCID”) to either the Randall Bold Water Treatment Plant or the new treatment plant currently under construction.
CCWD has requested $10 million in Federal grant funding for Fiscal Year 2009 for its Canal Emergency Flood Control Project. This project is intended to replace federally-owned earthen levees where Rock Slough transitions into the Contra Costa Canal (“Canal”) with an underground pipeline.
Approximately four miles of the current Canal consists of an open, earthen ditch without protective lining. In its current state, it is susceptible to contamination and failure in an earthquake that could potentially disrupt service to CCWD and the City.
It is proposed that the undergrounding of the Canal would do the following:
• Eliminate runoff and seepage which currently degrades the water quality.
• Reduces the need for upstream freshwater releases into the Delta to offset degradation.
• Increases the security of the CCWD and City drinking water supply.
• Reduces drowning hazards for the public in an area of on-going development.
As a partner with CCWD, the City is a stakeholder with a vested interest in the protection of these water resources. It is in the City’s best interest to show our support and partner with CCWD as they undertake this project to improve the quality of our drinking water.
