Infrastructure Projects & Scientific Studies

We partner with communities and organizations to create projects and studies that aim to improve our neighborhoods while capturing and cleaning stormwater.

The Safe, Clean Water Program invites municipalities, community organizations, nonprofits, and individuals to imagine, design, and implement stormwater infrastructure. These improvements prioritize green spaces and recreation areas in underinvested communities. These projects produce many benefits by:

  • Creating new park spaces and recreational opportunities
  • Growing our yearly collection of rainwater to supply water for millions of people in LA County annually
  • Improving flood protection through infrastructure upgrades
  • Increasing shade and reducing concrete, which reduces heat island effects
  • Protecting streams, creeks, rivers, and the ocean from pollution so they can be enjoyed by people and wildlife
  • Reducing trash and eliminating toxins and other harmful pollutants from stormwater runoff before it reaches our beaches

Additionally, the Safe, Clean Water Program provides funding for scientific studies that will bolster the effectiveness of the projects we design and implement and encourage innovation and adoption of new technologies and practices.

Types of Projects

Wondering what kinds of projects can improve water supply and quality while also greening our communities? Take a look:

  • Bioretention

    Bioretention projects, like rainwater gardens, collect and clean stormwater by filtering it through plants, soil, sand, and gravel.

  • Biofiltration

    Biofiltration relies on microorganisms to break down and remove pollutants in wastewater.

  • Infiltration Well

    Infiltration wells capture and preserve stormwater runoff before it reaches rivers, streams, and oceans.

  • Cistern

    Cisterns act as both above and below ground reservoirs that catch and store rainwater for future use.

  • Rain Barrel

    Rain barrels collect and hold stormwater runoff from roofs to use for lawns or indoor and outdoor plants.

  • Infiltration Facility

    Infiltration Facilities help to replenish groundwater by storing stormwater runoff and allowing it to gradually filter through the soil.

  • Treatment Facility

    Water Treatment Facilities intercept and treat stormwater so that it can be recycled to irrigate green spaces.

  • Sanitary Sewer

    These projects divert stormwater and other urban runoff to sanitary sewer systems for treatment.

  • Scientific Studies

    These studies can encourage innovation and adoption of new technologies and practices related to stormwater management.

From idea to implementation

How it works:

Each year, the Safe, Clean Water Program spends much of its revenue funding local infrastructure projects that increase water supply, improve water quality, and provide community enhancements. 

Municipalities should submit local stormwater project and program ideas as part of their Annual Plan. Learn more here.

Watershed-based project ideas from municipalities, individuals, community groups, and nonprofits are selected through a yearly call for proposals that solicits applications falling into one of three categories: 

  1. Infrastructure Program
  2. Technical Resources Program
  3. Scientific Studies Program 

Read on for a step-by-step overview to better understand the application process. For more in-depth instructions, download our Regional Program Funding Process Handbook.

  • We know that great ideas can come from anywhere. Whether you’re a municipality, community organization, nonprofit, or an individual feeling inspired to design or propose a project, we want to hear from you.

    The Program is designed to support a range of ideas, from fully fleshed out infrastructure projects to early stage proposals that need support determining feasibility to scientific studies that will bolster the effectiveness of the projects we design and implement.

  • Because each watershed has unique qualities, projects should be tailored to the needs of their location. Watershed coordinators are available to support and educate applicants on every step of the process, from application to implementation.

    Do you know your watershed or watershed coordinator? If not, we have a tool to help you find out.

  • A feasibility study is conducted to determine the feasibility of a proposed project and include a detailed investigation and report. All infrastructure projects seeking funding from the Safe, Clean Water Program must have completed a feasibility study.

    Need help conducting your feasibility study? The Safe, Clean Water Technical Resources Program can provide assistance. Apply here and reach out to your watershed coordinator for support.

    For more information on technical resources, visit the Technical Assistance Resources page.

  • Applications are submitted to the Watershed Area Steering Committee (WASC) through the Safe, Clean Water project portal.

  • Applications go through a series of evaluations and approvals based on a range of criteria, including water quality benefits, water supply benefits, community investment benefits, nature-based solutions, community support, and leveraging funds. The following bodies are part of the annual review process:

    • Watershed Area Steering Committees (WASCs) – Nine WASCs, each comprised of representatives from municipalities, agencies, and community stakeholders, review applications and determine which infrastructure projects are shared with the Scoring Committee for evaluation. Project concepts, studies, and scored projects are then deliberated by the WASCs as they determine which projects should be included in the annual Stormwater Investment Plan (SIP) for their watershed area.
    • Scoring Committee – The Scoring Committee, comprised of six subject matter experts in water quality benefits, water supply benefits, nature-based solutions, and community investment benefits, reviews the projects recommended by each WASC and indicates which are eligible for funding and which do not meet the scoring threshold.
    • Regional Oversight Committee (ROC) – This committee consists of nine subject matter experts with knowledge in water quality benefits, water supply benefits, nature-based solutions, community investment benefits, public health, sustainability, and other relevant issue areas. There are also two non-voting members representing the chair of the Regional Water Quality Control Board and the District. The ROC reviews each SIP submitted by the WASCs and evaluates how each plan will achieve the goals of the Program.
    • LA County Board of Supervisors – The ROC shares its findings with the LA County Board of Supervisors along with a recommendation of whether or not the Board should approve each WASC’s SIP. Final decisions about which projects receive Program funding are made by the LA County Board of Supervisors annually.

  • Projects and studies that are approved for funding must complete a fund transfer agreement between the project developer and the Los Angeles County Flood Control District in order to receive Program funds.

    You can download a sample fund transfer agreement here.

    Once approved, the Safe, Clean Water Program requires reporting and independent audits to ensure that everyone who receives funding fulfills the objectives and goals of the Program. Refer to the Reporting and Accountability Page to learn more.
