Marin Civic Center Green Stormwater Infrastructure Project

Marin County is preparing to undertake the construction of green stormwater infrastructure improvements at the Civic Center campus and the 1600 Los Gamos Drive County facility parking lot. The project will involve the installation of bioretention facilities and associated stormwater drainage enhancements designed to better manage runoff and treat pollutants, specifically targeting compliance with NPDES Phase II Total Maximum Daily Load requirements for polychlorinated biphenyls and mercury. These improvements aim to reduce the transport of harmful contaminants into local waterways by enhancing natural filtration processes and increasing stormwater capture and infiltration capacity. The work will be concentrated within the urban confines of San Rafael, California, with the primary performance location identified as the 94903 ZIP code area. The project is forecasted for a July 2026 release, with Liza DeFrain, Senior Planner for Marin County, listed as the primary point of contact for inquiries via email and phone. While no solicitation number or NAICS code has been assigned yet, the initiative aligns with broader environmental compliance goals for the county and reflects a commitment to sustainable urban infrastructure. The project does not currently indicate any specific set-aside provisions for small businesses or disadvantaged groups, and all communications and updates will be accessible through the California Environmental Quality Act portal for public transparency.
