The purpose of designating wetlands and wetland transition areas as critical areas is to assure that density calculations for various types of planned developments result in a unit construction that can be accommodated on the subject lands without encroaching upon the wetlands. The designation of wetlands and wetland transition areas as a critical land factor is to signal the location of environmentally fragile lands which should be incorporated in open space plans or located within a portion of a lot which need not be physically developed. Further, Montgomery Township embraces the policy of the State of New Jersey as established by the Freshwater Wetlands Protection Act, N.J.S.A. 13:9B-1 et seq., that freshwater wetlands are a finite and valuable resource and that activities in or affecting wetlands should not destroy the natural wetland functions important to the public safety and general welfare. Any disturbance of wetlands and wetland transition areas is subject to the approval of NJDEP Division of Land Resource Protection.
