Overview
The 2026 Street Surface Seal Project is a key part of South San Francisco’s ongoing Pavement Management Program. This project focuses on preserving roadway conditions and extending pavement life in the Winston Manor and Serra Highlands neighborhoods. The work includes applying a protective surface treatment, commonly referred to as a “slurry seal,” to approximately 440,000 square yards of existing asphalt streets.
The project also includes several critical maintenance and safety enhancements:
- Structural Repairs – Repairing damaged pavement prior to sealing through localized base repairs and crack sealing to prevent water infiltration.
- Surface Treatment – Applying a full surface seal to protect the roadway from sun exposure and moisture, extend pavement life, and improve skid resistance.
- Safety Striping – Refreshing painted curbs and replacing worn pavement markings with new, high-visibility striping and pavement markings.

Frequently Asked Questions
Who will be performing this work?
The City has contracted with Dryco Construction, Inc. for this project. Founded in 1985, Dryco Construction has successfully delivered numerous paving projects throughout the Bay Area.
Will there be road closures, traffic impacts, or access issues during construction?
Yes, temporary lane closures and detours will be in place during construction. Every effort will be made to maintain access for vehicles, pedestrians, and cyclists, including access to nearby driveways, throughout the construction period.
Please drive carefully through construction zones to ensure the safety of both the public and construction workers.
What should we expect during construction?
Temporary “No Parking” signs and electronic message boards will be posted in advance of work. Access to active construction zones will be limited; however, priority access will be maintained for local residents. Affected residents will also receive advance notice of scheduled work.
