14.08.020 Definitions. <br />Unless specifically defined below, words or phrases used in this chapter shall be interpreted so as to <br />give them the meaning they have in common usage and to give this chapter it's most reasonable <br />application. <br />Accessory Structure <br />A structure on the same parcel of property as a principal structure and the use of which is <br />incidental to the use of the principal structure. For floodplain management purposes, the <br />term includes only accessory structures used for parking and storage. <br />Alteration of watercourse <br />Any action that will change the location of the channel occupied by water within the banks of <br />any portion of a riverine waterbody. <br />Appeal <br />A request for review of the county floodplain administrator's interpretation or application of <br />any provision of this chapter or a request for a variance. <br />Area of shallow flooding <br />A designated AO, AH, or AR/AH Zone on the Flood Insurance Rate Map (FIRM) with a one <br />percent or greater annual chance of flooding to an average. depth range from one to three <br />feet, a clearly defined channel does not exist, the path of flooding is unpredictable and <br />indeterminate, and velocity flow may be evident. AO is characterized as sheet flow and AH <br />indicates ponding. <br />Area of special flood hazard <br />The land in the floodplain within a community subject to a one percent or greater chance of <br />flooding in any given year. Designation on FIRM maps include the letters A, AO, AH, Al -30, <br />AE, A99 and AR. Also referred to as "100-year floodplain" and "special flood hazard area." <br />Agriculture <br />"Agriculture" is the grazing, feeding, and watering of livestock; plowing, seeding, cultivation, <br />and harvesting for the production of crops and pasture; soil and water conservation <br />practices; the maintenance of farm or stock ponds, irrigation ditches, irrigation structures, <br />drainage ditches, underground drainage systems, fences and farm roads, the control of <br />noxious weeds or other generally accepted agriculture practices, and for purposes of this <br />chapter does not include associated structures and/or appurtenances. <br />ASCE 24 <br />The most recently published version of ASCE 24, Flood Resistant Design and Construction, <br />published by the American Society of Civil Engineers. <br />Base flood <br />The flood having a one percent chance of being equaled or exceeded in any given year. Also <br />referred to as the "100-year flood." <br />Base flood elevation <br />The computed elevation to which flood water is anticipated to rise during the base flood <br />period. Base Flood Elevations (also referred to as BFEs) are shown on Flood Insurance Rate <br />Maps (FIRMs) and on the flood profiles. The BFE is the regulatory requirement for the <br />elevation or floodproofing of structures. Relationship between the BFE and a structure's <br />elevation determines the flood insurance premium. <br />Basement <br />Any area of the building having its floor subgrade (below ground level) on all sides. <br />Best available information <br />
