Intent. In order to provide for the health, safety and welfare of the present and future population of the County, the Planning Commission shall only approve a proposed subdivision when such subdivision would not bring about the development of land which is unsuitable due to flooding, poorly drained soils, excessive erosive action by water, unstabilized slope or fill, or other conditions which may cause danger to life, health or property or aggravate erosion or flood hazards or when the lands involved would, in its opinion, become unsuitable through the development proposed. Additionally, the Planning Commission shall only approve a proposed subdivision where it finds that such subdivision would bring about the development of land which is not of such high environmental sensitivity that its development would have undue adverse impacts upon tidal or nontidal wetlands, the one-hundred-year floodplain, forest stands, existing significant trees, greenways, areas of critical or special habitat, water bodies on the state's impaired waters list or having an established total maximum daily load requirement, and source water and aquifer recharge protection areas.
