No land shall be subdivided for any use which is determined by the plan commission/board of appeals and the village board after investigation to be unsuitable for such use by reason of flooding or bad drainage, adverse earth or rock formation or topography, or any other feature likely to be harmful to the health, safety or welfare of the future residents in the proposed subdivision or to the community. However, if the subdivider agrees to make improvements which will, in the opinion of the village engineer, make the area safe for occupancy and provide adequate lot and street drainage and storm water detention facilities, the subdivision may then be approved. For flood limits refer to FEMA flood insurance rate map dated September 3, 1997, as well as the U.S. department of interior, U.S. geological survey in cooperation with the Northeastern Illinois plan commission including all supplements published by the U.S. geological survey.
