Excludes environmentally sensitive and flood-prone land from designation as vacant or available for purposes of affordable housing construction.

This bill excludes environmentally sensitive and flood-prone land from being counted as available for affordable housing construction under New Jersey's fair share housing law. Specifically, it requires municipalities to exclude lands regulated by state or federal agencies - including those in Highlands Preservation Areas, flood hazard zones under the Flood Hazard Area Control Act (P.L.1962, c.19), and wetlands protected by the Freshwater Wetlands Protection Act (P.L.1987, c.156) - from calculations of "vacant" land. Municipalities must now exclude these areas when determining their affordable housing obligations, preventing such lands from being used to meet housing requirements. The change updates existing law to explicitly include these regulated lands in the exclusion list.
