Marin Stormwater Resource Plan

Marin Stormwater Resource Plan


On August 28, 2014, the California State Legislature passed SB 985, amending the Stormwater Resource Planning Act. The Act requires that municipalities develop a Stormwater Resource Plan (SWRP) to be eligible for bond-funded grants for stormwater and dry weather runoff capture projects.

The State Water Board has a set of SWRP Guidelines that municipalities must satisfy to be eligible for grant funding. SWRPs must be a watershed-level resource planning document that describes watershed issues, identifies project opportunities with multiple benefits, and creates a prioritized list of project opportunities based on quantifying multiple benefits. For stormwater capture and reuse projects, multiple benefits might include augmenting the water supply, improving water quality, reestablishing the natural water drainage or mimicking natural ecosystems, enhancing or restoring habitat, and/or providing community benefits.

Marin SWRP Development

MCSTOPPP has developed a countywide SWRP for Marin's 11 cities and towns and the County. The SWRP identifies publicly-owned parcels and streets as potential sites for stormwater capture and reuse projects, and scores the sites based on a multi-benefit project opportunity analysis methodology. MCSTOPPP has worked with many public agencies to stitch together existing documentation, reports, and plans to create a Functionally Equivalent SWRP that is consistent with Marin's planning efforts and satisfies the SWRP Guidelines.

Please note that the sites listed are a list of potential project opportunities that do not currently have designs or funding, and are in no way a commitment by the municipalities or the county to implement projects at these locations. The goal of the plan is to identify sites where stormwater capture and reuse projects may be feasible, and to rank them according to a multiple benefit methodology, to satisfy SWRP Guidelines so the sites are no longer ineligible for bond-funded grants.
