The Bipartisan Infrastructure Law will invest more than $44 billion in the Clean Water and Drinking Water State Revolving Funds, or SRFs, presenting a tremendous opportunity to finance natural infrastructure solutions that can improve water quality and protect communities against flooding. While natural infrastructure can be a cost-effective way to improve water quality and reduce flood risk, these projects have historically been difficult to finance through SRFs due to a lack of consistent repayment streams.

EDF and Quantified Ventures recently published a report that identified five replicable repayment streams that communities and conservation groups can use to access SRF financing for natural infrastructure such as wetlands, floodplain restoration, and riparian buffers. These repayment streams include stormwater utility fees, source water protection fees, and environmental markets.
