(a) The flood hazard areas of Sioux Falls, South Dakota, are subject to periodic inundation which results in damage to persons and property, health and safety hazards, disruption of commerce and governmental services, and extraordinary public expenditures for flood protection and relief, all of which adversely affect the public health, safety and general welfare.
(b) These flood impacts are created by the unusual and rapid accumulation or runoff of surface waters from any source, the cumulative effect of obstructions in floodplains which cause an increase in flood heights and velocities, and by the occupancy of flood hazards areas by uses vulnerable to floods and hazardous to other lands because they are inadequately elevated, or otherwise protected from flood damage.
