Todd Road and Standish Avenue Intersection Improvements Project

The Todd Road and Standish Avenue Intersection Improvements Project, managed by Sonoma County Public Infrastructure under solicitation 2025091118, involves upgrading a 2.66-acre site in unincorporated Sonoma County. The scope of work includes installing a traffic signal, new storm drain inlets, and ADA-compliant curb ramps at each leg of the intersection. Additionally, the project will implement standard curb radii, sidewalk improvements, four new push-button crossings with striping, and Class II bicycle lanes and signage on both sides of Todd Road. Construction will occur primarily within existing county right-of-way, though a small property acquisition of less than one-tenth of an acre is required for curb compliance. The project adheres to AASHTO standards, the 2020 Caltrans Highway Design Manual, and the Sonoma County General Plan 2020. Environmental compliance has been addressed through a Mitigated Negative Declaration under CEQA, with specific focus on protecting biological resources such as the California tiger salamander and burrowing owl. Key regulatory requirements include potential CESA Incidental Take Permits and strict adherence to U.S. DOT regulations for the transport of hazardous materials. The project is led by Assistant Engineer Olguin P. Caban, and final environmental documentation was filed in January 2026 following a public review period and consultation with the California Department of Fish and Wildlife.
