This section is in development...


Welcome to the CASQA Stormwater Funding Resource Portal. The portal was created to assist member agencies and other California municipalities in navigating the complex landscape of funding stormwater programs and projects. It contains information, links, and references, to guide you in developing sustainable funding for stormwater programs and projects.  

As we continue to populate the portal, we invite your feedback and recommendations for additional links or resources that should be considered for inclusion. Contact Us


To support the establishment of stormwater management programs and funding of stormwater projects in California through the identification of resources, funding opportunities, and related guidance.

Overview and Background

California law poses unique challenges to funding stormwater programs and projects. This overview provides some background on Proposition 218 and the recently passed Senate Bill 231.

Sustainable Stormwater Program Funding

Stormwater programs, including operations, maintenance, and regulatory compliance activities, can be supported through a variety of funding sources. Stormwater utility fees and special taxes require voter approval. Other strategies such as developer fees, special financing districts, capital improvement bonds, or realigning duties to other departments can be completed without ballots. This section helps you identify the possibilities.

Project Funding

Stormwater infrastructure projects require planning and capital investments. Grants, bonds, and loans are traditional sources of funding. Utilities also need to understand how to estimate costs. This section helps in planning future buildout of stormwater systems. 

Regional Studies

A few regional studies have been done exploring stormwater funding opportunities and the associated barriers and opportunities. This section presents these studies.
