-12- give this Ordinance its most reasonable application. EQUAL DEGREE OF ENCROACHMENT - a standard applied in determining the location of a floodway limits so that flood plain lands on both sides of a stream are capable o£ conveying a proportionate share of flood flows. This is determined by considering the hydraulic conveyance of the floodplain along both sides oP a stream for a significant reach. FLOOD - a temporary rise in stream level that results in inundation of areas not ordinarily covered by water. FLOOD FREQUENCY - the average frequency statistically determined, for which it is expected that a specific flood level or discharge may be equalled or exceeded. FLOODWAY - the channel of the watercourse and those portions of the adjoining flood plains which are reasonably required to carry and discharge the regional flood. FLOODWAY FRAME - that portion o£ the regional floodplain located outside oE the floodway. PERSON - any natural person, firm, partnership, association, or corporation, but this definition does not include governmental units. REACH - a hydraulic engineering term to describe longitudinal segments o£ a st_ream or river. A reach will generally include the segment of the flood hazard area where flood heights are influenced by a man-made or natural obstruction. In an urban area, the segment o£ a stream or river between two consecutive bridge crossings would typically constitute a reach. REGIONAL FLOOD - the flood which is representative of large floods known to have occurred generally in the area and reasonably characteristic of what can be expected to occur on a particular stream. The regional flood generally has a flood frequency of approximately 100 years as determined by an analysis of floods on a partiaular stream and other streams in the same general region. REGIONAL FLOOD PLAIN - the area inundated by the regional flood (100 year frequency flood). This is the flood plain area which shall be regulated by the standard, and criteria of this ardinance. REGIONAL FLOOD PROTECTION ELEVATION - the elevation oP regional flood plus one foot of freeboard to provide a safety £actor. STRUCTURE - anything constructed or erected on the ground including but without limitation to buildings, factories, sheds, cabins, mobile homes, and other similar items. SUBDIVISION - means the division of any parcel of land shown as a unit or as con- tiguous units on the last preceding records of the County Auditor into two or more parcels, sites or lots, any one of which is less than five acres for the purpose, whether immediate or future, of transfer of ownership. Subdivision also includes the improvement of one or more parcels of land for residential, business or industrial structures or groups of structures involving the
