Funding Opportunities / Grants and Loans

Many state and federal agencies offer grants to improve water infrastructure, restore habitat, green urban areas, capture and conserve stormwater, and clean up groundwater; some agencies also offer low-interest loans and, at times, loan forgiveness. A convenient way to keep track of grant funds becoming available under Proposition 1, which funds many of the current grant programs, is to visit the state's Bond Accountability website periodically here for project solicitation notices. The Bond Accountability website organizes the information by program. One can also subscribe to the Proposition 1 listserve to be kept informed by email of relevant information. Finally, one can view a master schedule which is regularly updated that tracks each of the Proposition 1 programs.

Another valuable source of information on grants and loans is the California Financing Coordinating Committee (CFCC) website. The CFCC was formed in 1998 and is made up of seven funding agencies: five state and two federal. CFCC members facilitate and expedite the completion of various types of infrastructure projects by helping customers combine the resources of several agencies. Project information is shared between members so additional resources can be identified. CFCC members conduct free Funding Fairs statewide each year to educate the public and potential customers about the different member agencies and the financial and technical resources available. The tabs below give more detail on various types of grants and loans programs. Available materials which describe the programs and the process by which to apply for funding should be read carefully and directions should be followed closely.

Additionally, the California Infrastructure and Economic Development Bank's (IBank) Infrastructure State Revolving Fund (ISRF) Program is a useful low-cost financing tool for public agencies, including special districts, assessment districts and joint powers authorities, as well as non-profit corporations sponsored by public agencies. Eligible projects include but are not limited to city streets, drainage, water supply and flood control, environmental mitigation measures, parks and recreational facilities, sewage collection and treatment, and water treatment and distribution. ISRF Program funding is available in amounts ranging from $50,000 to $25 million, with loan terms for the life of the project up to a maximum of 30 years. Sources of financing repayment may include enterprise revenues, general fund revenues, property assessments, Mello-Roos, special taxes, and other recurring revenues acceptable to IBank. The IBank's Small Business Finance Center also offers loans through its Farm Loan Program. Funds can be used for, among other things, operating and production expenses, equipment, and soil and water conservation.

Finally, a number of forums and workshops have been held in recent years on developing successful stormwater financing strategies.  Through a collaboration between the new West Coast Environmental Finance Center, located at California State University, Sacramento, U.S. EPA, and the Water Boards, stormwater financing forums were held in April 2017 in Oakland and Los Angeles.  The agenda for the Los Angeles forum can be accessed here.  Presentations from both of the forums can be downloaded from the following webpages:
Los Angeles:

Prior to establishment of the West Coast Environmental Finance Center, the U.S. EPA in collaboration with the Water Boards held a knowledge exchange workshop in Los Angeles in 2015. The U.S. EPA invited the East Coast Environmental Finance Center housed at the University of Maryland to provide information during the workshop.  The presentation from that workshop can be found at: University of Maryland EFC Presentation ; a manual produced by the Center in 2014 can be downloaded at EFC Local Government Stormwater Financing Manual

Water Quality-Focused Grant and Loan Programs

The State Water Resources Control Board, Division of Financial Assistance administers various financial assistance programs, including loans and grants for constructing municipal stormwater capture and use and/or stormwater treatment facilities, sewage treatment facilities, and water recycling facilities; improving public water systems; groundwater cleanup projects; watershed protection projects; and for non-point source pollution control projects. Each program briefly described below has its own guidelines, application process and funding cycle. Many grant programs receive funding currently from Proposition 1. For the latest information, access the State Water Board's Division of Financial Assistance website at and the summary of funding programs at Applications for many programs can be submitted through the Financial Assistance Application Submittal Tool (FAAST) at Some grant programs may offer the opportunity to submit pre-proposals via FAAST for early feedback; potential applicants are strongly encouraged to do so in order to develop proposals that are consistent with the funding program's guidelines. Potential applicants should subscribe online to the funding program's announcements and updates sent via email. Sign-up at:

Proposition 1 requires the State Water Board to operate a multidisciplinary technical assistance program for small disadvantaged communities, and allows for the State Water Board to fund technical assistance (TA). The State Water Board's Office of Sustainable Water Solutions was created to promote permanent and sustainable solutions to help ensure effective and efficient provision of safe, affordable, and reliable drinking water and wastewater treatment services. The Office is focused on addressing both financial assistance and TA needs, with a focus on Small Disadvantaged Communities (DACs). The Office provides direct assistance to potential funding applicants, as well as contracting and coordination with external TA providers. Assistance may involve project coordination and development, legal assistance, engineering, and environmental analysis, and/or leak detection/water audits. The application deadline is continuous.

In 2017, the U.S. Environmental Protection Agency (EPA) launched the Water Finance Clearinghouse, a web‐based portal to help communities make informed financing decisions for their drinking water, wastewater, and stormwater infrastructure needs. The Clearinghouse provides communities with a searchable database with more than $10 billion in water funding sources and over 550 resources to support local water infrastructure projects. It consolidates and expands upon existing EPA-supported databases to create a one-stop-shop for all community water finance needs. The Water Finance Clearinghouse was developed by EPA's Water Infrastructure and Resiliency Finance Center, an information and assistance center that provides financing information to help local decision makers make informed decisions for drinking water, wastewater, and stormwater infrastructure to reach their public health and environmental goals.

U.S. Environmental Protection Agency

FUNDING PROGRAM: Urban Waters Small Grants Program

The program seeks to help local residents and their organizations, particularly those in underserved communities, restore their urban waters in ways that also benefit community and economic revitalization.

Habitat Restoration-Focused Grant Programs

Multiple agencies offer grant programs which feature habitat restoration as their main focus. However, there may be ancillary water quality benefits from undertaking the restoration, particularly when restoration involves streams or wetlands. Many of these grant programs are currently funded by Proposition 1 and require matching funds, often of non-State origin. These types of projects may be an opportunity to partner with other entities to obtain multiple sources of funding that might lead to more quantifiable water quality gains from habitat restoration. Proponents of projects listed in the workplan for the Southern California Wetlands Recovery Project may want to pursue these types of funding.
