FISCAL IMPACT:
Estimated Project cost: $10,700,000.00. (100% Local Road Funds.)
BACKGROUND:
The purpose of the projects is to perform preventative maintenance and rehabilitation of roads throughout the County using routine pavement surface treatments. The project will apply a slurry seal, mill and overlay, and/or reconstruct various roads in areas such as, but not limited to, Crockett, Rodeo, Port Costa, Danville, Blackhawk and Diablo. Additionally, a portion of Rodeo Creek Trail (along Rodeo Creek) from Seventh Street to Willow Avenue will be treated with a slurry seal. 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. Replacement of existing curb ramps and/or curb work in compliance with the American with Disabilities Act may be performed in these areas. Work may also include striping for Bicycle facilities and replacing existing thermoplastic stripes and pavement markings along Viewpoint Boulevard in Rodeo. Construction is anticipated to begin in Summer 2026 and last 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. A temporary traffic control system will be implemented during construction. Residential streets will be closed for up to approximately four hours 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. Vegetation trimming and tree removal may be necessary.
The project consists of minor alterations, involving negligible or no expansion of use to existing roads, including performing preventative maintenance and repairs pursuant to Article 19, Section 15301(c) of the CEQA Guidelines.
CONSEQUENCE OF NEGATIVE ACTION:
Delay in approving the project may result in a delay of design and construction, and may jeopardize funding.
