Document Description
The purpose of the project is to perform preventative maintenance and rehabilitation of roads throughout the County using routine pavement surface treatments. The project will apply a slurry seal, microsurface seal, cape seal, thin and/or thick overlay, and/or reconstruct various roads including but not limited to East Richmond Heights, Kensington, and South Walnut Creek (Shell Ridge and Rudgear areas). Additionally, a mill and overlay will be applied to Clark Road in El Sobrante from Jana Vista Road to the East Bay Regional Park District gate. Prior to the surface treatments, pavement preparation, consisting of weed spraying, crack sealing, base failure repairs, leveling, patching, and/or edge grinding may be necessary. Work will include adjusting and setting survey monuments and replacing existing thermoplastic stripes and pavement markings. Bicycle facilities may be striped along Arlington Avenue in Kensington and Rudgear Road in South Walnut Creek. Replacement of existing curb ramps and/or curb work in compliance with the American with Disabilities Act may be performed in Kensington and South Walnut Creek. Construction is anticipated to start in May 2025 and last for approximately five months. The project will maintain the existing drainage pattern and will not create new impervious areas. Appropriate Best Management Practices (BMPs) will be implemented to protect storm drain inlets. Temporary traffic control will be necessary. Residential streets will be closed for approximately half a day in order to apply road surface treatments and to provide sufficient time for it to adhere to the road surface. Residents will be notified prior to street closures and if night and weekend work may be needed. “No Parking” signs will be posted the day before actual road surface treatment application. Emergency vehicles will have access at all times. Tree and vegetation trimming and removal may be necessary.
