STORMWATER RESOURCE PLAN


Contra Costa Watersheds Stormwater Resource Plan (SWRP)

The Contra Costa Clean Water Program (CCCWP) is pleased to announce the release of the Contra Costa Watersheds Stormwater Resource Plan: Greening the Community for Healthy Watersheds (CCW SWRP). The CCW SWRP was submitted to the State Water Board, East Contra Costa County Integrated Regional Water Management Group, and the Bay Area Integrated Regional Water Management Plan (IRWMP) in January 2019. The State Water Board issued its concurrence with the SWRP in February 2020. The CCW SWRP can be viewed or downloaded using the links in the side navigation bar.

The CCW SWRP was created to advance stormwater management projects and programs within Contra Costa County. The plan builds upon a foundation of support for and successful implementation of watershed protection programs, restoration projects, and low impact development throughout the County. These projects value stormwater as a resource and provide multiple benefits for the community. The CCW SWRP identifies potential stormwater management projects and programs that are eligible to apply for grant funds like the Proposition 1 Storm Water Grant Program. You are invited to view the SWRP Projects and Project Opportunities using the SWRP Project Viewer, a GIS-based web mapping application. The CCW SWRP is a living document and will be periodically updated to reflect changing regulatory requirements and implementation strategies. Updates of the SWRP are expected to occur every five-years.   Following the initial publication in January 2019, the SWRP Project list will be dynamically updated and maintained in the SWRP Project Viewer. The public and watershed stakeholders are encouraged to recommend additional projects for the SWRP. Please use the “Suggest a Project” form using the links in the side navigation bar and your idea will be routed to appropriate jurisdiction(s) where the project is located. If you don’t hear back on your suggested project within a few weeks, please contact the jurisdiction representative or CCCWP at (925) 313-2360.


Stormwater Resource Planning and Proposition 1

Assembly Bill (AB) 1471 Water Quality, Supply, and Infrastructure Improvement Act of 2014 (Prop 1) was approved by California voters in the general election on November 4, 2014. Among other funds, Prop 1 provided $200 million for a Storm Water Grant Program for multi- benefit stormwater management projects. Multi-benefit stormwater management projects include green infrastructure (GI), rainwater and stormwater capture projects, and stormwater treatment facilities.

Prior to the passage of Prop 1 in November 2014, the California Legislature adopted SB 985 – the Storm Water Resource Planning Act. SB 985 amended the Water Code to require the development of a SWRP to receive grants from a bond act approved after January 1, 2014 for stormwater and dry weather runoff capture projects. A SWRP must use a watershed-based planning approach to develop a prioritized list of multi-benefit stormwater management projects. The SWRP must be developed in accordance with the State Water Board’s SWRP Guidelines.

In summer 2016, the CCCWP was awarded a Prop 1 planning grant for development of the Contra Costa Watersheds Stormwater Resource Plan. The committed grant amount for the project was $499,180 with a match amount of $500,760. The grant agreement was finalized in May 2017 and work commenced on the project. The CCW SWRP was finalized and submitted to the State Water Board, the East Contra Costa County Integrated Regional Water Management (IRWM) Group and the Bay Area IRWM Plan in January 2019. The Bay Area IRWMP adopted the CCW SWRP on February 25, 2019. The East County IRWM Group incorporated the CCW SWRP into the 2019 IRWM Plan update. Following updates to the final SWRP, the State issued a concurrence letter accepting the SWRP in February 2020. The Contra Costa SWRP will position local jurisdictions to compete for Prop 1 implementation grants and any future bond monies for stormwater and dry weather capture projects.
