Tecolote Canyon Trunk Sewer Improvement & Golf Course Water Connection

Project Description

This project provides for the rehabilitation and replacement of 4.7 miles of trunk sewer pipe in Tecolote Canyon. These repairs and upgrades will prevent sewer line ruptures and provide additional capacity to the sewer system. Project activities include sewer line maintenance, installation and replacement of manholes and access path improvements to facilitate future maintenance. Both open trench and trenchless methods for replacing and rehabilitating the trunk sewer will be used, depending on the area of the canyon. Trenchless work will occur in environmentally sensitive locations and will include the use of a steel casing, a jacking pit and a receiving pit.

This project will also install 700 linear feet of 16-inch water main to service the Tecolote Canyon Golf Course and provide redundancy in the water system for the efficient delivery of water to the surrounding communities.

Other activities include the construction of stream crossings and manhole protections. Revegetation plans include a 120-day plant establishment period, 25-month monitoring for vegetated areas and 60-month monitoring for all restoration areas.

For everyone's safety, anyone visiting the area is asked to use caution and stay a safe distance from any construction activity.

Current Work (Updated June 9)

The pipeline installation of the sewer pipe from the Nature Center to the USD entrance has been completed. Construction operations will now be from the USD entrance to the Tecolote Golf Course.
The contractor is currently cleaning up and restoring the Nature Center parking lot.
Sections of the hiking trail are temporarily closed for public safety due to heavy construction vehicle traffic, limited space within the trails, deep excavations and around-the-clock construction activities.
For additional details on trail closures, see the project flyer.
- Phase 1a remains closed 24/7. This phase stretches from the Nature Center to the University of San Diego (USD) access point and requires an around-the-clock closure of this portion of the trail through fall 2025.
- Phase 1b is closed until 5 p.m., Monday through Friday. This phase runs north of the USD access point. The September Street trail loop will not be impacted by the current work and will remain open. During Phase 2, the main trail will remain open north of the USD access point.
