Palos Verdes Reservoir - Final Design

NOE - Notice of Exemption

Document Description
The Metropolitan Water District of Southern California (Metropolitan) Palo Verdes Reservoir has a 28-acre Hypalon floating cover. The floating cover is approaching 20 years old and is at the end of its useful life. In the past, the floating cover has experienced numerous tears in the cover material. Repair of these tears has become increasingly difficult due to aging of the material. Recently, Metropolitan discovered deterioration of the underside of the cover over large areas. In addition, the reservoir's existing gunite-concrete surface has several areas of damage, which will require installation of a new membrane liner and subdrain system to collect and convey flows, and to reduce excess hydrostatic pressures. Metropolitan will coordinate with the California Department of Health Services for appropriate inspection and maintenance activities at Palos Verdes Reservoir during the interim period until a new floating cover is installed. Metropolitan is proposing to prepare final design for the replacement cover and associated repairs.
