O'Shaughnessy Sewer System Repairs Project

The O'Shaughnessy Sewer System Repairs Project, sponsored by the San Francisco Public Utilities Commission and led by the San Francisco Planning Department, involves the rehabilitation of eight manholes and the replacement of approximately 334 feet of wastewater collection line between manhole locations 2 and 5. Specific work includes replacing manholes 2, 5, and 7, installing a new manhole at location 1, and performing various repairs such as epoxy sealing, grouting, and the installation of riser rings and concrete aprons at other locations. The project is classified under NAICS code 237110 and was officially approved on September 25, 2025, following a Common Sense Exemption from environmental review under CEQA Section 15061(b)(3). Construction activities will take place in San Francisco, California, adjacent to roadways, with strict requirements that no work occurs within the roads or causes damage to them. To ensure site protection, all culverts, rock walls, headwalls, and other features associated with Hetch Hetchy Road must be flagged for avoidance before construction begins. Primary administrative contact for the project is Senior Planner Timothy Johnston, and the project is associated with case number 2025-004774ENV.
