Document Description
Initial Study and Environmental Checklist The Joint Regional Water Supply System (JRWSS) transmission main is a water pipeline constructed in 1961 to convey potable water from Irvine to San Clemente, California, part of which is contract operated by South Coast Water District. A 2000-foot section in a residential area needs upgrading and is difficult to access for maintenance or repair. The intent of this project is to construct 2,350-foot replacement segment in Crown Valley Parkway and safely abandon the existing pipeline segment in place.
