Various Locations Large Diameter Sewer Improvements No 1

candidate project Design 26bd175b-d767-428e-99c1-5c64ef9dffa9

The Various Locations Large Diameter Sewer Improvements No. 1 is a sanitary sewer project owned by San Francisco Public Works (Hydraulic Infrastructure Design and Construction division). The work spans dozens of street segments across the city, including stretches of 1st, 4th, 6th and 10th Avenues, 17th Street, Anza, Greenwich and Guerrero Streets. It is currently active and in the design phase, with construction scheduled to run from March 2027 to April 2028 — about four months later than its earlier planned timeline. No cost figures have been published.AI-generated
