The topography of the proposed subdivision shall be preserved wherever possible in its natural state by minimizing grade changes on the property. No grade change shall be permitted that would require the installation of a retaining wall or other engineered device within any required yard to protect or support the subject property or any adjacent lot. Areas on a lot designated for development shall be designed so as to preserve the natural features of the lot, avoid disturbance of areas of environmental sensitivity, including wetlands, floodplains, slopes in excess of 15%, ravines and habitat of endangered wildlife, and minimize negative impacts to or alteration of natural features. The existing landscape shall be preserved in its natural state by minimizing the removal or destruction of existing trees and other natural features on the property, so that the resulting development shall be in keeping with the general appearance of the surrounding area and will not adversely affect the ecology of the area.
