The project will consist of trenchless work on St Louis Terrace, Soledad Avenue and Crespo Drive and is not expected to affect sewer service.

Construction will begin in the spring on a city of San Diego sewer rehabilitation project on three La Jolla streets: St Louis Terrace between Viking Way and Little Street, Soledad Avenue between Sierra Mar Drive and Crespo Drive and along parts of Crespo Drive in La Jolla.

Four other San Diego neighborhoods are also included in the project: Clairemont Mesa; Rancho Peñasquitos; Mira Mesa; and Otay Mesa-Nestor.

The work is necessitated as those sewer mains were built between the 1950s and 1971 and have been identified by the city’s Public Utilities Department as needing “special attention due to their condition,” said project manager Roberto Valadez with the Engineering & Capital Projects Department at the Feb 6 meeting of the La Jolla Community Planning Association.

The project’s proposed scope of work consists of the trenchless rehabilitation of approximately 5,752 feet of existing eight- and 10-inch sewer mains, including the refurbishment of about 33 manholes, installation of 60 linear feet of eight-inch sewer main pipes and replacement of two four-inch sewer laterals, along with two cleanouts and more.

The two new cleanouts will require approximately 25 square feet of excavation and take place in previously disturbed soil and won’t trigger environmental regulations, Valadez said. 

Construction is expected to happen between spring 2025, likely April, and fall 2026; the contractor will deliver door hanger notices to property owners at least one week before work begins on their respective streets. Each street should be affected for about two weeks.

Sewer service to residents in the affected areas will not be interrupted, Valadez said, with work happening from 7:30 am to 3:30 pm weekdays. No night work is expected in La Jolla.

No parking issues are expected, Valadez said. 

All residents received a notice about the impending project in November.

The city is in the process of finalizing the construction award to a contractor, Valadez said,
