Prop 1 SWGP Background

Prop 1 (Assembly Bill 1471, Rendon) authorized $7.545 billion in general obligation bonds for water projects including surface and groundwater storage, ecosystem and watershed protection and restoration, and drinking water protection. The State Water Board will administer Prop 1 funds for five programs. Of the $7.545 billion, Prop 1 (Section 79747) provides $200 million in grant funds for multi-benefit storm water management projects.

Water Code section 79747 identifies funds available for multi-benefit storm water management projects which may include, but shall not be limited to: green infrastructure, rainwater and storm water capture projects and storm water treatment facilities. Storm Water Resource Plans, or functionally equivalent plan(s), are required to obtain grant funds for storm water and dry weather capture projects.

Storm Water Resource Plans and Concurrence Review Process

Water Code section 10563 (as amended by Senate Bill 985) requires public agencies to develop a SWRP or functionally equivalent (FE)-SWRP as a condition of receiving grant funds from a bond (approved after January 2014) for storm water and dry weather runoff capture projects. The intent of Senate Bill 985 is to encourage the use of storm water and dry weather runoff as a resource to improve water quality, reduce localized flooding, and increase water supplies for beneficial uses and the environment. Water Code section 10565 requires the State Water Board to establish Guidelines for entities developing a SWRP or FE-SWRP. The SWRP Guidelines were adopted by the State Water Board on December 15, 2015.

It is the responsibility of the applicant to self-certify completeness of the SWRP or FE-SWRP; however, the State Water Board will verify that the Water Code and SWRP Guidelines requirements were properly addressed through a concurrence review process. A SWRP or FE-SWRP self-certification checklist must be signed by the authorized representative and reviewed by the State Water Board in order to confirm eligibility to receive SWGP grant funds.

Even though the SWRPs are due within ninety (90) days of the final Prop 1 implementation grant award funding list being issued, we encourage applicants to have their plans reviewed in advance. Please submit your SWRP or FE-SWRP, a completed self-certification checklist, and a cover letter explaining the approach used to arrive at a functionally equivalent document (if applicable) with your FAAST implementation grant application to swgp@waterboards.ca.gov to obtain State Water Board concurrence review.
