New Jersey Proposes Lower Coastal Construction Elevation Standards

New Jersey's Department of Environmental Protection (DEP) has proposed updated flood elevation rules for new construction in coastal and flood-prone areas, reducing the required elevation from 5 feet to 4 feet above FEMA's Base Flood Elevation. This adjustment reflects updated climate science projections predicting a sea-level rise of 4.4 feet by 2100, a decrease from earlier estimates, and incorporates feedback from public comments and stakeholders concerned about affordability and feasibility. The new rules, part of the Resilient Environments and Landscapes (REAL) program, aim to balance protecting communities from future flooding and storm surge impacts while considering economic and design flexibility, including provisions for emergency vehicle access. The changes will be open for public comment and likely finalized by the end of 2025, allowing projects submitted before the effective date to follow existing regulations. DEP Commissioner Shawn LaTourette emphasized the importance of evolving science and public input in shaping these standards to enhance coastal resilience without compromising safety. These updated standards will increase building heights relative to FEMA requirements but represent a moderated approach compared to the initial proposal, reflecting both scientific updates and community concerns.
