Title

El Monte Pipeline No 2

Description

The project proposes rehabilitation and repairs along 12.2 miles of the existing El Monte Pipeline, including the Grossmont Tunnel. The purpose of the rehabilitation is to extend the pipeline’s service life, enhance operational efficiency, and improve reliability. Improvements are proposed at approximately 69 locations comprising 1.35 acres along the existing pipeline, including improvements to and reconstruction of existing appurtenances, such as air valves, blowoffs, and access structures; installation of new isolation valves; and open trench replacement of approximately 450 feet of deteriorated pipeline along El Monte Road. The project would also include repairs to curbs and gutters, sidewalks, and Americans with Disabilities Act (ADA) ramps at affected intersections, repairs to ornamental landscape in previously developed areas and native plant revegetation in open space areas. The pipeline alignment is located in the cities of Santee, La Mesa, El Cajon, and San Diego and the unincorporated community of Lakeside. The project is approximately 12.2 miles long and extends from near Lake Jennings in the northeast to the Alvarado Water Treatment Plant at Lake Murray in the southwest (Navajo Community Planning Area, Council District 7).
