Much progress has been made in recent weeks on the SDG&E’s Bear Valley Parkway Replacement Project – Pipeline Safety Enhancement Plan (PSEP) To date, it is about 75% complete.

After starting construction in November 2020, San Diego Gas and Electric Company crews have trenched more than two miles along Bear Valley Parkway between San Pasqual Valley Road and Beethoven Drive and installed 11,000 feet of new pipe.

In March, construction crews completed installing new pipe along a 2,800-foot section along Mule Hill Trail in the San Dieguito River Park. The trail is open again for hikers with a temporary fence for future habitat restoration. Habitat restoration areas will be seeded in Fall 2021 with native seed that was collected onsite pre-construction. The seed mixes include grassland and coastal sage scrub. Restoration monitoring and maintenance will continue for the next several years.

To accommodate increasing school and other traffic along Bear Valley Parkway as COVID-19 restrictions ease, crews have switched to overnight work for the next 6 to 8 weeks.

For the next several weeks, crews will be working along Bear Valley Parkway at night. Construction work zones for pipe installation will typically be about 1,000 feet long.  On an average day, about 160 feet of pipe will be installed in the trench. 

Reduced traffic lanes may be necessary along Bear Valley Parkway between Las Palmas and Beethoven Drive Monday-Friday until May 31, 9 p.m.-5 p.m.

Traffic control will be set up and flaggers present during these activities.  Residents and businesses along Bear Valley Parkway will have in and out access during this time.  Follow the direction of traffic control signs and flaggers as detours are subject to change depending on the location of construction activities.  Please plan accordingly and anticipate delays.    

Current work activities consist of pot holing, saw-cutting and excavating the trench to prepare for the pipeline replacement. The pipe will contain a special coating to protect it from corrosion. Once installed, it will be welded and x-rayed. Once that is complete, additional pipeline safety features will be installed in the trench, including a yellow warning mesh to prevent accidental dig-ins and fiber optic technology that will detect leaks, intrusion and ground disturbances and alert us immediately. Restoration and repaving activities will finalize the project’s construction.

When complete, the natural gas pipeline safety project will replace 3.5 miles of 1949-vintage pipe in Escondido along Bear Valley Parkway between San Pasqual Valley Road and Beethoven Drive and through an approximate half-mile section of Mule Hill Trail in the San Dieguito River Park.
