Development is improper and therefore prohibited which may result in loss and damage to public and private improvements through inundation by flood waters and subsequent expensive construction of storm sewers' and other public projects, in the permanent destruction of natural resources, loss of water retention facilities, open space and wildlife habitats and impairment of public and private water supplies.
