Wetlands (as officially defined under federal and/or state regulations) shall not count towards more than 50% of the required minimum lot area. The Township may require an applicant to prove that a lot will contain sufficient contiguous buildable land area that is outside of wetlands. This subsection shall only apply to a lot within a subdivision or land development submitted for approval after the adoption of this chapter.

It shall be the responsibility of each applicant to determine whether land areas proposed for alteration meet the federal or state definition of a "wetland" prior to submittal of development plans to the Township. If the Zoning Officer has reason to believe that wetlands may be present on a site proposed for development or subdivision, the Zoning Officer may require that the applicant provide a suitable wetland delineation study prepared by a qualified professional.

A minimum setback of 20 feet shall be required between any new principal building for which a building permit is issued after the effective date of this chapter and any wetland.
