If the Village Planning Commission finds that land proposed to be subdivided is unsuitable for subdivision development due to flooding, bad drainage, steep slopes, inadequate water supply, transportation facilities, and other such conditions which may endanger health, life, or property; and, if from investigations conducted by the public agencies concerned, it is determined that in the best interests of the public, the land should not be developed for the purpose proposed, the Commission shall not approve the land for subdivision unless adequate methods are advanced by the subdivider for meeting the problems that will be created by the development of the land.
