Makes various changes to powers and duties of NJ Infrastructure Bank.

S 3472 creates a new "Community Hazard Assistance Mitigation Program" (CHAMP) for the New Jersey Infrastructure Bank to provide loans for hazard mitigation and resilience projects. The program will fund projects undertaken by state entities, local government units, and nonprofit organizations, including allowing local governments to provide loans to private property owners for measures like floodproofing and wind retrofits. It includes a graduated loan forgiveness program that provides full forgiveness for households earning 50-80% of median income and partial forgiveness for higher-income households. The bill also extends the deadline for the bank to stop incurring new debt from 2033 to 2053.
