In order to provide for the health, safety and welfare of the present and future population of the town, the Planning Commission shall refuse to approve any proposed subdivision when such subdivision would bring about the development of land which is unsuitable for such use due to flooding, lack of drainage, excessive erosive action by water, unstabilized slope or fill or other conditions which may cause danger to life, health or property or aggravate erosion of flood hazards or when the lands involved would, in its opinion, become unsuitable through the development proposed.
