FLOOD PLAIN ZONE SECTION XXXII-A I. PURPOSE It is the purpose of this Section to promote the public health, safety, and general welfare, and to minimize flood losses by provisions designed to: A. Restrict or prohibit uses which are dangerous to health, safety or property in times of flood or which cause increased flood heights or velo- cities. B. Require that uses vulnerable to floods, including public facilities which serve such uses, be pro- vided with flood protection at the time of initial construction. C. Protect individuals from buying lands which are unsuited for intended purposes because of flood hazard. II. DEFINITIONS CHANNEL: A natural or artificial low lying land area with definite bed and banks to confine and conduct continuously or periodically flowing water. ENCROACHMENT: See Obstruction. EQUAL DEGREE OF ENCROACHMENT: A standard applied to the evaluation of the effects of uses requiring approval of location on increases in flood heights. It assumes that an encroachment if permitted may confer on all pro- perty owners on both sides of the stream an equal right to encroach to the same degree within that reach. Since the factors affecting hydraulic efficiency are usually not uniform within a reach this will usually not result in equal distances between encroachment lines and the sides of the stream. FLOOD: A temporary rise in a water course flow or stage that results in water overtopping its banks and inundating areas adjacent to the channel. FLOOD PLAIN: The relatively flat area or lowlands adjoining the channel of a stream or watercourse and subject to flood water overflow. FLOOD PROFILE: Engineering conclusions, based upon his- torical facts and/or generally accepted engineering principles, represented on a graph or other medium, showing the relationship of the water surface elevation of a flood to the lands surrounding the channel. - 17 -
