Document Description
The South Coast water District (District) is the contract operator for a large water main known as the Joint Transportation Main (JTM). The District proposes the replacement of a 42-inch, 30-inch, 24-inch and 8-inch isolation valves along the 60-inch JTM and a 24-inch Eastern Transmission Main (ETM) located in the City of Laguna Woods. These valves and flow meter have not been operated in several decades and have become inoperable. The valves associated with the JTM will require repair and replacement. The valve vaults will be raised to grade for future safe access and maintenance. Due to the size, depth, and location of the vaults, the construciton activities will require large excavations and removal of some trees and other vegetation to provide contractor access.
