McAllister Street, 20th Street, and 24th Street Pavement Renovation and Sewer Replacement Project

Project Description
San Francisco Public Works and the San Francisco Public Utilities Commission have partnered to complete infrastructure improvements on several blocks throughout San Francisco as part of the McAllister Street, 20th Street, and 24th Street Pavement Renovation and Sewer Replacement Project. Our partnership allows us to minimize impacts to the public by consolidating our work whenever possible. This project will include sewer main replacement/rehabilitation, curb ramp installation, street base repairs, grinding (removal of existing asphalt) and repaving.

Construction is scheduled to begin at the first location in September 2024 with completion expected at the last location in October 2025. San Francisco Public Works will manage the project during construction. The work hours may vary by location; however, the typical working hours are 7:30 a.m. to 5 p.m., Monday through Friday. Weekend work is allowed but is not anticipated at this time.

Below is a list of the blocks included in this contract:

• McAllister Street (Masonic Avenue to Divisadero Street)
• 20th Street (Eureka Street to Castro Street)
• 24th Street (Homestead to Castro Street)
• 24th Street (Noe Street to Guerrero Street)
• 25th Street & Douglass Street intersection
   

Note: Not all blocks will include sewer main replacement or rehabilitation work. The blocks scheduled to include sewer work are as follow:

• McAllister Street (Masonic Avenue to Broderick Street)
• 20th Street & Diamond Street intersection
• 20th Street & Castro Street intersection
• 24th Street (Fair Oaks Street to Quane Street)
• 24th Street (Vicksburg Street to Sanchez Street)

Typically, the first phase of work on a block will include sewer main replacement and/or rehabilitation (lining). Once the new sewer main has been installed, or the existing one is lined, our engineers will review video of the sewer laterals to determine which, if any, need to be replaced. The sewer laterals are the connection between the main and the curb/sidewalk. Note: Sewer laterals are only replaced on an as-needed basis depending on the condition of the existing line. Sewer service will not be interrupted during construction. Please continue to use your household and business plumbing as usual.

Once the sewer work is complete on a block, crews will begin preparations to repave a block. Preparations may include concrete street base replacement work. This task will require the contractor saw-cut, excavate the broken concrete, and pour fresh cement. Replacing any damaged/broken street base now will help prolong the durability of the new pavement. This may happen at several locations along the block. Preparations may also include the installation of ADA compliant curb ramps at 4-way intersections and T-intersections.
