"Flood Zone Clarification Act"; modifies procedure for delineation of State flood hazard areas.

The bill modifies how New Jersey defines flood hazard areas by requiring the state to set flood hazard boundaries no more than one foot above the Federal Emergency Management Agency's (FEMA) 100-year flood elevation for each watercourse. It prohibits the Department of Environmental Protection (DEP) from implementing or adopting its proposed "NJPACT Rules" (which would have set flood hazard areas five feet above FEMA levels) before June 1, 2038, without legislative approval. The DEP must update flood hazard delineations within three months of any FEMA updates and must seek legislative authorization before adopting new rules related to flood hazard areas. This affects property owners, developers, and local governments in flood-prone areas by changing the standards for development permits under the Flood Hazard Area Control Act.
