All applicants with wetlands on site are required to obtain a wetlands delineation and letter of interpretation (LOI) from the New Jersey Department of Environmental Protection. This applies to both saltwater and freshwater wetlands.

No building, structure or use shall be permitted within areas defined as wetlands by the New Jersey Wetlands Act of 1970 and delineated on the wetlands maps prepared by the New Jersey Department of Environmental Protection, except in accordance with a permit issued under the Act.
