Project Description

The San Diego County Water Authority is preparing for construction on Pipeline 4 in the communities of Scripps Ranch, Pomerado and the Marine Corps Air Station Miramar. The project consists of the installation of a steel liner in 26,048 lineal feet of existing 69-inch, and 84-inch pipe located in the Scripps Ranch area and on the Marine Corps Air Station Miramar, specifically from Scripps Lake Drive south to the State Route 52 Freeway. Pipeline 4, together with Pipelines 3 and 5, form the Second San Diego Aqueduct, one of two underground pipeline aqueduct systems delivering water to San Diego County.

Location of Construction Portals

Relining work is conducted via 40-foot-long sections of pipe that are excavated to gain access to the interior of the pipe and to introduce relining materials. These construction portals will remain active for approximately five months. Not all portals will be active
at the same time, however. Pipeline relining is done in several phases, and work may shift from one portal to another depending on which phase is under way.

In addition to the construction portals, other locations along the pipeline will be used to support relining activities. Concrete, ventilation and power may be introduced into the pipe at these locations. No excavation will be necessary at these locations, which will be used intermittently during the eight-month-long relining project.

Impacts to Miramar Ranch Elementary School

This project will impact Miramar Ranch Elementary School, as Pipeline 4 lies directly beneath school grounds. One of the construction portal sites is located south of Miramar Ranch Elementary School, 200 feet south of Red Cedar Drive within the existing easement. There will also be construction activity on the school grounds surrounding a 30-inch-diameter man way near the portable classrooms. There will be construction crews, equipment, both air handling and concrete pumping units, concrete trucks, grouting materials, and small trucks in this area. A sound wall will be built around the structure to reduce the noise created to a level permitted under the City of San Diego noise abatement ordinances. Work hours are currently scheduled from 7 a.m. to 7 p.m. Monday through Friday. The Water Authority is working closely with school officials and community leaders to minimize the impacts of relining activities including noise, dust and traffic to the school and the surrounding community.
