Stormwater Resource Plan
Draft Stormwater Resources Plan Public Review and Comment.
The Contra Costa Clean Water Program is pleased to announce the release of the Public Review Draft of the Contra Costa Stormwater Resource Plan: Greening the Community for Healthy Watersheds (CCW SWRP).
The CCW SWRP used a watershed-based planning approach to compile existing stormwater management project concepts and develop potential project concepts designed to improve Contra Costa watersheds and communities. The potential projects identified in the CCW SWRP will help clean water in creeks and bays while providing additional community and environmental benefits.
The CCW SWRP can be viewed or downloaded using the links in the side navigation bar or the links below. Please use the comment submittal form to provide your comments and suggestions on the CCW SWRP. All comments must be received by October 1, 2018.
Contra Costa Watersheds Stormwater Resource Plan (SWRP)
The 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, which provides matching grants to public agencies, nonprofit organizations, public utilities, state and federally recognized Native American tribes, and mutual water companies for multi-benefit stormwater management projects. Multi-benefit stormwater management projects include 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 FY 2016/17, the CCCWP Management Committee made a strategic decision to apply for a Prop 1 SWGP planning grant to develop a SWRP for CCC. There were several reasons for this decision. For CCCWP Permittees to compete for Prop 1 implementation grants and any future bond monies for stormwater and dry weather capture projects, they must develop a SWRP. The requirements for development of a SWRP are also very similar to the required elements of the MRP 2.0 mandated GI Plans (Provision C.3.j). For example, both call for: 1) focusing water quality priorities based on watersheds, management areas or specific drainage areas; 2) identifying and prioritizing projects using quantitative measures or metrics; 3) prioritizing projects that provide multiple benefits; 4) establishing procedures for tracking progress and implementation of performance measures; and 5) conducting outreach and education, and encouraging public participation. CCCWP Permittees made the decision to apply for funding for a SWRP and to leverage the SWRP planning process and deliverables to develop components for the MRP 2.0 mandated GI Plans.
In summer 2016, the CCCWP was awarded a Prop 1 planning grant for development of the Contra CostaWatersheds Stormwater Resource Plan. The committed grant amount for the project is $499,180 with a match amount of $500,760. In order to meet MRP 2.0 compliance deadlines, the Program launched the SWRP planning process on an accelerated schedule in February 2017, while the grant agreement documents were being finalized by the California State Water Resources Control Board. The final grant agreement was signed on May 2, 2017.
Grant tasks that were accomplished in FY 2016/17 include:
- Formation of a Technical Advisory Group (TAG) composed of Permittees, non-governmental organization (NGO) representatives, Water Board representatives, and other government agency representatives. The TAG members represent a wide range of stakeholder interests in the SWRP process, as well as a wide range of geographic areas across CCC. The first TAG meeting was held on June 27, 2017.
- Gathered data and planning documents from jurisdictions across the county for the planning process; compiled, reviewed, and summarized the data, and prepared a preliminary draft technical memorandum summarizing the data and data gaps.
- Distributed a request for information on existing stakeholder projects for inclusion in the SWRP. This request was distributed widely throughout the county and generated significant response from municipalities and other government agencies, and well as watershed stakeholder groups.
- Gathered watershed characterization information and prepared a preliminary draft planning area description, map, and boundaries memorandum.
- Prepared a preliminary draft SWRP outline.
- Prepared a preliminary draft memorandum describing the approach to addressing water quality compliance in the SWRP.
- Developed a draft stakeholder outreach and engagement plan and began stakeholder outreach. There will be five stakeholder engagement workshops in late summer and fall 2017; regular presentations and updates on plan development will be given at bimonthly Contra Costa Watershed Forum (CCWF) meetings. The first presentation was given at the May 2017 meeting.
Grant tasks accomplished in FY 2017/18 include:
- Finalized the Stakeholder Engagement Plan and conducted five Stakeholder Workshops, in the North, South, East, West and Central areas of the County, to gather input and potential projects for inclusion in the SWRP. These outreach efforts generated over 500 projects, from concepts to those being planned to those in progress.
- Provided updates to the Contra Costa Watershed Forum and to the Bay Area and East Contra Costa Integrated Regional Water Management (IRWM) groups
- Submitted quarterly Progress Reports
- Held two meetings of the Technical Advisory Group to review key project deliverables
- Completed all of the preliminary information collection, data gathering, planning, and technical evaluations and preliminary required by grant and needed for the SWRP including:
- Completed data collection and watershed descriptions
- Developed the SWRP annotated outline
- Developed the SWRP implementation strategy
- Evaluated modeling tools and developed the recommended modeling approach
- Developed and completed screening process for stakeholder-submitted projects
- Completed geospatial modeling to identify potential projects based on geography, hydrology, drainage patterns, land uses, available parcels.
- This effort generated 18,000 potential project opportunities.
- Scored the projects opportunities based on SWRP multiple benefits criteria. Permittees reviewed and prioritized the project opportunities
- Selected 10 projects and developed them into GI BMP project concepts
- Completed and submitted the SWRP Administrative Draft.
