New Jersey Resilient Environments and Landscapes (REAL) Rules

New Jersey’s Resilient Environments and Landscapes (REAL) rules, adopted in January 2026, represent a landmark regulatory reform effort by the New Jersey Department of Environmental Protection (NJDEP) to better account for climate change and future conditions in development and environmental protection. New Jersey is particularly vulnerable to the effects of climate change due to its extensive coastline, urban density, and critical infrastructure in low-lying areas. The REAL rules, and the broader Protecting Against Climate Threats (NJ PACT) initiative, are designed to better support New Jersey communities, residents, and businesses in building resilience to sea-level rise, extreme weather, chronic flooding, and other impacts of a changing climate. In particular, the rules modernize flood hazard area standards and incorporate climate-informed requirements, prioritize nature-based shoreline protection solutions, and update stormwater management and wetland protection standards to better reflect changing precipitation and hydrologic conditions.

Regulation within the Flood Hazard Area (N.J. Admin. Code § 7:13)

The REAL rules transform flood hazard area standards by introducing a new Climate-Adjusted Flood Elevation (CAFE) and an Inundation Risk Zone (IRZ). The rules strengthen construction standards and expand the floodplain within which a permit must be obtained for proposed development.

REAL amends the Flood Hazard Area Control Act Rules to redefine the flood hazard area within which development is subject to regulation and permitting requirements, using the new climate-adjusted flood elevation (CAFE) approach. The flood hazard area is defined by the land and space above the land that lies above the CAFE. For tidal areas, the CAFE is intended to accommodate the effects of sea-level rise on flood elevations through the year 2100, and is determined by adding four feet to the 100-year flood elevation as determined by either NJDEP or FEMA, whichever is greater. For fluvial (riverine) regulated waters, the CAFE is determined as the higher of either 2-feet above the NJDEP Design Flood Elevation, or 3-feet above the FEMA 100-year flood elevation.

Within the flood hazard area, the rules also incorporate a new Inundation Risk Zone (IRZ), which is defined as “the portion of a tidal flood hazard area that has been determined to be at

significant risk for future permanent or daily inundation by 2100” as determined by scientific findings from Rutgers University. For regulated activities proposed within an IRZ, developers must comply with additional considerations and mitigation measures, including completion of a new Inundation Risk Assessment and alternatives analysis demonstrating that future tidal flooding projections have been incorporated into project design.

Nature-Based and Resilience-Focused Design (Coastal Zone Management Rules, N.J. Admin. Code § 7:7)

The REAL rules also amend New Jersey’s Coastal Zone Management Rules, strengthening protections for beaches, dunes, and coastal wetlands and prioritizing nature-based shoreline stabilization methods. The rules prioritize nature-based solutions for coastal resilience, including living shorelines, marsh restoration and enhancement, and the beneficial reuse of dredged materials. New coastal development must incorporate forward-looking climate science and resilience-based engineering documentation, including inundation criteria for structural siting and layout.

Stormwater Management Updates (N.J. Admin. Code § 7:8)

The rules modernize stormwater standards to reflect higher rainfall volumes and more frequent flooding statewide. Key changes include incorporating county-specific precipitation adjustment and future change factors, requiring stormwater quality treatment for reconstruction of motor vehicle surface areas even without added impervious area, and mandating green infrastructure as the primary compliance pathway. A five-year review cycle for precipitation data is codified to keep standards current.

Wetlands and Freshwater Protections (N.J. Admin. Code §§ 7:7A, 7:38)

Revised freshwater wetlands rules require more site-specific evaluation of hydrologic change, redevelopment impacts, and ecological function. Wetland conservation is strengthened by limiting development in wetland areas, promoting restoration of degraded wetlands, and adapting to saltwater intrusion from rising sea levels. Exceptional resource value wetlands and trout production waters receive heightened protections. It classifies wetlands by resource value and maintains a tiered permit structure.

Affordable Housing and Overburdened Communities

The REAL rules include a hardship exception that allows qualifying projects to seek relief from certain elevation and siting requirements where strict compliance would be infeasible. Affordable housing developments are expressly recognized as presumptively satisfying the “compelling public need” prong of this test, meaning they do not need to separately justify why the project serves a public interest. Applicants must still demonstrate that the regulated activities would not pose a threat to public health, safety, and welfare, and must meet the exception's remaining criteria.

NJDEP has also emphasized that the rules are intended to increase resilience in urban and overburdened communities that have historically experienced chronic flooding and poor water quality, and that the cost of resilience measures such as elevation is marginal relative to the long-term savings in flood insurance costs and avoided property damage and loss of life.

Permitting Process Modernization

The REAL rules also restructure NJDEP's permitting framework for regulated activities. The previous system of permits-by-rule was largely repealed and replaced with a tiered structure (ranging from categorical exemptions and streamlined registration pathways to individual permits) designed to align the level of review with the nature, scale, and expected environmental effects of a proposed activity.

Five Year Data Review

NJDEP committed to revisiting the sea-level rise and precipitation data incorporated into the rules every five years beginning on Jan. 20, 2026, and amending the regulations as appropriate to reflect evolving climate science.

NJDEP proposed the REAL rules in August 2024, published a Notice of Substantial Change in July 2025 reflecting public and stakeholder feedback, and formally adopted the rules on January 20, 2026. The amended rules contain regulations to allow certain applications to be reviewed under the previous regulations for 180 days after REAL's adoption, referred to as “legacy” provisions. The legacy period expires on July 20, 2026. To qualify, permit applications must be deemed administratively and technically complete by NJDEP before that date.
