In July 2016, San Francisco Public Works began roadway improvements on San Marcos and Santa Rita avenues that would include sewer replacement, stairway repair, concrete work on curbs, and sidewalk and driveway replacement. All sewers have been visually inspected via video camera and evaluated by San Francisco’s Public Utility Commission. An evaluation and condition assessment of the sewers under this project were completed and identified for full segment replacement. During detailed design, we explored trenchless technologies. Under this project and where appropriate, two sewer location segments were designed for trenchless rehabilitation. The remaining locations were designed for open cut replacement.
