Subdivisions should be planned to take advantage of the topography of
the land, to economize in the construction of drainage facilities, to reduce
the amount of grading and to minimize the destruction of trees and topsoil.
If any portion of the land within the subdivision is subject to flooding
or other hazards, due consideration shall be given to such problems in the
design of the subdivision. Land subject to flooding and land otherwise uninhabitable
shall not be planned for residential occupancy nor for such other uses that
may increase danger to health, life or property or may aggravate the flood
hazard.
