Executive Summary:
Sonoma County Public Infrastructure (SPI) requests that the Board approve a Project Specific Maintenance Agreement (PSMA) with Caltrans for the SR-12 Pedestrian Crossing Improvements at Waterman Avenue and Central Avenue (Project W12050) and delegate authority to the Director of SPI to execute the agreement. The PSMA establishes the respective maintenance responsibilities of the County and Caltrans for specified improvements within State right-of-way and is required before Caltrans can issue the final encroachment permit for construction.
Discussion:
The SR-12 Pedestrian Crossing Improvements Project will upgrade the existing marked crosswalks on SR 12 at Waterman Avenue and Central Avenue. Improvements include pedestrian-activated solar-powered Rectangular Rapid Flashing Beacons (RRFBs), overhead pedestrian lighting, ADA-compliant curb ramps and sidewalk improvements, high-visibility crosswalk markings, signage, and associated concrete and pavement work.
Sonoma County Public Infrastructure (SPI) has completed design of the Project. The Project is categorically exempt from the California Environmental Quality Act (CEQA) under the Class 1 Existing Facilities exemption pursuant to CEQA Guidelines Section 15301, and a Notice of Exemption was filed with the County Clerk and State Clearinghouse in September 2025 (State Clearing House No. 2025090726). With design and environmental review complete, SPI anticipated advertising and awarding the construction contract in early 2027 using the Road Commissioner’s authority under Sonoma County Code Section 2-29. Because the Project is located within State right-of-way, construction will be performed under an encroachment permit issued by the California Department of Transportation (Caltrans).
In preparation for construction of the improvements within State right-of-way, the County and Caltrans must establish their respective responsibilities for ongoing maintenance of the improvements. The proposed Project Specific Maintenance Agreement (PSMA) establishes these responsibilities. Under the PMSA, the County will maintain the RRFB systems, sidewalks, ADA curb ramps and detectable warning surfaces, as well as any decorative or stamped concrete pedestrian improvements. The County will also be responsible for costs associated with the operation, maintenance, repair, replacement, and energy needs of the solar-powered RRFB systems at Waterman Avenue and Central Avenue. Caltrans will remain responsible for maintaining roadway pavement markings within the traveled way, including crosswalk markings, lane lines, bicycle lane striping and symbols, fog lines, stop bars, directional arrows, raised pavement markers, and similar markings.
Maintenance activities performed within State right-of-way must comply with applicable State standards, and the County must obtain any required Caltrans encroachment permit before entering State right-of-way to perform maintenance. Approval of the proposed PSMA will formalize the respective ongoing maintenance responsibilities of Caltrans and the County for the project improvements.
SPI requests that the Board adopt a resolution approving the proposed PMSA with Caltrans for the SR 12 Pedestrian Crossing Improvements at Waterman Avenue and Central Avenue and authorize the Director of SPI to execute the Agreement.
