National Culvert Removal, Replacement, & Restoration Grants – FY24 (Year 3)

The Bipartisan Infrastructure Law established the National Culvert Removal, Replacement, and Restoration Grant program (Culvert Aquatic Organism Passage Program) to provide funding for projects that would meaningfully improve or restore passage for anadromous fish (anadromous fish species are born in freshwater such as streams and rivers, spend most of their lives in the marine environment, and migrate back to freshwater to spawn).
