One More Year Under the Old Flood Rules: NJDEP Extends the REAL Legacy Deadline to July 2027

On September 21, 2026, the New Jersey Department of Environmental Protection (“NJDEP”) extended by one year the deadline that decides which version of the State’s flood hazard, freshwater wetlands, coastal zone, and stormwater rules governs a development project. The deadline, now July 20, 2027, controls access to what the Department calls legacy treatment: the right to have a project reviewed under the standards in place before the Resilient Environments and Landscapes (REAL) rules took effect.

REAL was adopted on January 20, 2026 and recast all four programs around projected rather than historic climate conditions. Legacy treatment remains available for individual and general permits, verifications, letters of interpretation, transition area waivers, and water quality certificates, on an application NJDEP deems both administratively and technically complete. The Department need not confirm completeness before the deadline; an application that was complete when filed keeps legacy status even if confirmed afterward. Permits-by-registration and general-permits-by-certification do not benefit.

REAL’s new Climate-Adjusted Flood Elevation requires construction in tidal flood areas to sit four feet above FEMA’s 100-year flood elevation. The rules also map Inundation Risk Zones for areas projected to flood as seas rise, widen riparian buffers, lower wetlands mitigation thresholds, and pull more redevelopment into stormwater review. On a constrained site, that can determine how high a building sits, how much of the parcel is usable, and whether the project remains financially viable.

The extension is a delay rather than a repeal. NJDEP has described the year as time to weigh targeted amendments to the rules. While industry groups have welcomed the additional time, environmental organizations called it a rollback, citing flood risk. REAL nonetheless remains on the books as adopted, although challenges by industry associations and three Jersey Shore counties remain pending in court. 

For projects now in the pipeline, it is vital to ensure permit applications with NJDEP are complete. An application the Department ultimately finds incomplete, and that is resubmitted after the cutoff, will lose legacy status entirely, so the practical deadline is prior to the new July 20, 2027 date.
