Public Notifications & Community Meetings

2023/2024 Street Surface Seal Project

This project will provide asphalt pavement maintenance of several residential, collector, and arterial streets in Downtown and Old Town neighborhoods of the City of South San Francisco (City) as part of the Pavement Management Program (PMP).

With over 140 centerline miles of roadway, the pavement network represents a highly visible and valuable asset to the community and local businesses.

Residents of the City identified the condition of the roadways as a priority concern through public outreach by City Council and the City Manager. As a result, City Council secured funding for yearly asphalt pavement maintenance projects that will repair localized failed sections of the asphalt pavement prior to application of Surface Seal. New high visibility, thermoplastic lane line delineation, legends and markings will be applied once the surface seal treatment has had a chance to set / cure for a minimum of 7 to 10 days.

City PW Engineering staff has divided the City into 6 distinct areas that are naturally divided by major arterial roads as shown in the map (2023-2028 Surface Seal Map and Schedule)

By performing a preventive maintenance treatment to the asphalt pavement roadways in a systematic approach, the City is able to extend the life span of our roadways and provide cost effective protective surface treatment with increased visibility. The surface seal treatment protects the asphalt pavement from water infiltration, from degradation of the asphalt binder in the asphalt pavement caused by UV rays, and provides a new dark wearing surface with increased roughness to prevent slick conditions in inclement weather. In addition, the installation of new high visibility, thermoplastic lane line delineation, speed limit legends, stop legends, limit lines, and crosswalks enhance visibility in the day, at night and during inclement weather. Using the systematic approach of concentrating the work by areas allows for contractors to provide competative bids in comparison to having to account for loss of production and downtime in their bids due to projects with street segments that are spread out throughout the City.

This program will bring meaningful and long-lasting improvements to the community, and enhance street aesthetics and multimodal transportation functions. The project will provide immediate increase to the City’s network pavement condition index (PCI) and send a positive message to resident’s who have concerns with roadway conditions.

The Project also includes several improvements to the City’s existing bicycle network. A major goal of the City is to improve bicyclist comfortability, accessibility, and interconnectivity of the bike network in the City.

Aside from the practical aspects of the project, the City incorporated requirements for multiple advance notifications into the construction contract so that residents, businesses and public services are made aware of this upcoming street work and the dates and times when residents will be impacted by the work.

Street parking will be temporarily impacted during construction. Temporary No Parking signs will be deployed notifying the public of sections of street parking that will be impacted by the scheduled construction. Work will may also result in temporary sidewalk closures as work is underway. The work is scheduled from 8:00 a.m. to 5:00 p.m. Monday through Friday. Residents can expect minor delays through the work zones during construction. Temporary pedestrian detour signage will be deployed noting safe path of travel. Pedestrians are encouraged to use alternate routes. Please follow signage and safety personnel instructions at all times.

The work on this project will occur in 3 Phases.

  • Phase 1 only includes repair of localized failed asphalt pavement areas in the roadway.
  • Phase 2 will start at completion of Phase 1 and is a "Winter Suspension" as the project will not be able to proceed during inclement weather season.
  • Phase 3 includes the removal of existing lane delineation, application of crack seal, application of surface seal, and installation new thermoplastic lane line delineation.

City anticipates Phase 1 will start in early October 2023 and conclude in early December 2023. Phase 2 will conclude by April 10, 2024 or at the start of Phase 3.
