It is the express purpose of this section and article to promote the preservation of natural features in the Township of Vernon in respect of the unique and varied nature of the same. Whenever an application shall be made for an approval or permit pursuant to or involving this article, the applicant shall establish in writing or in hearing that no significant disturbance of natural features, including but not limited to trees, woodlands, streams, ridgelines, scenic vistas, wetlands, open waters, rock outcroppings, and topsoil is proposed or anticipated; or, in the event that the same is proposed or anticipated, then the applicant shall establish how and to what extent such features shall be preserved to the satisfaction of the reviewing official or Board. This section shall not be construed so as to relieve an applicant for site plan or subdivision approval of the responsibility of submitting a site-specific and informative environmental impact statement when the same is required pursuant to this chapter. Whenever disturbance of natural features appears necessary, the maximum extent of natural features consistent with the reasonable and permitted or approved use of the property shall be preserved.
