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.
