Granada Trunk Line Replacement Project

The Los Angeles Department of Water and Power (LADWP) proposes to replace the existing Granada Trunk Line (GTL), which is a potable water trunk line located in the Porter Ranch and Granada Hills neighborhoods of the City of Los Angeles. The Granada Trunk Line Replacement Project (proposed project) would include the replacement of approximately 26,411 feet of the GTL primarily within Rinaldi Street in two sections, or units. Unit 1 would consist of an approximately 13,228-foot portion of the GTL extending from Balboa Boulevard to Yolanda Avenue. Unit 2 would consist of an approximately 13,183 foot portion of the GTL extending from Yolanda Avenue to LADWP’s De Soto Reservoir Regulator Station. The entirety of the trunk line would be replaced with 48-inch-diameter piping. In addition to replacement of the GTL, the proposed project would also replace manholes, isolation valves, blow-off valves, and combination air/vacuum valves along the trunk line.
