WHEREAS, the City of Batesville on July 27, 1982, adopted an Ordinance known as the City of Batesville, Arkansas, Flood Hazard Prevention Code, and; WHEREAS, there are certain amendments and additions that are required to clarify the existing code, now; BE IT THEREFORE CONSIDERED AND ORDAINED that the following additions are hereby incorporated into the Flood Hazard Prevention Code and made a part thereof as follows: ARTICLE 2 - DEFINITIONS Article 2 of said Flood Hazard Prevention Code shall be amended to add the following definitions: ELEVATED BUILDING -- means a nonbasement building (i ) built, in the case of a building in Zones Al-30, AE, A, A99, A0, AH, B, C, X, and D, to have the top of the elevated floor, or in the case of a building in Zones V1• 30, VE, or V, to have the bottom of the lowest horizontal structure member of the elevated floor elevated above the ground level by means of pilings, columns (posts and piers) , or shear walls parallel to the floor of the water and (ii ) adequately • anchored so as not to impair the structural integrity of the building during a flood of up to the magnitude of the base flood. In the case of Zones A1-30, AE, A, A99, AO, AH, B, C, X, or D, "elevated building" also includes a building elevated by means of fill or solid foundation perimeter -falls with openings sufficient to facilitate the unimpeded movement of flood waters. In the case of Zones V1-30, VE, or V, "elevated building" also includes a building other- wise meeting the definition of "elevated building" , even though the lower area is enclosed by means of breakaway walls if the breakaway walls meet the stand- ards of Section 60. 3(e)(5) of the National Flood Insurance Program regulations. EXISTING CONSTRUCTION - means for the purpose of determining rates, struc- tures for which the "start of construction" commenced before the effective date ' of the FIRM or before January 1, 1975, for FIRMS effective before that date. "Existing construction" may also be referred to as "existing structures" . FLOOD PROTECTION SYSTEM - means those physical structural works for which funds have been authorized, appropriated, and expended and which have been con- structed specifically to modify flooding in order to reduce the extent of the areas within a community subject to a "special flood hazard" and the extent of the depths of associated flooding. Such a system typically includes hurricane tidal barriers , dams, reservoirs, levees or dikes. These specialized flood modifying works are those constructed in conformance with sound engineering standards. FUNCTIONALLY DEPENDENT USE - means a use which cannot perform its intended purpose unless it is located or carried out in close proximity to water. The term includes only docking facilities, port facilities that are necessary for the loading and unloading of cargo or passengers, and ship building and ship repair facilities, but does not include long-term storage or related manufact- . uring facilities. HABITABLE FLOOR - means any floor usable for the following purposes ; which includes working, sleeping, eating, cooking or recreation, or a combination thereof. A floor used for storage purposes only is not a "habitable floor" . NEW CONSTRUCTION - means, for flood plain management purposes, structures for which the "start of construction" commenced on or after the effective date of a flood plain management regulation adopted by a community. WATER SURFACE ELEVATION - means the height, in relation to the National Geodetic Vertical Datum (NGVD) of 1929 (or other datum, where specified) , of floods of various magnitudes and frequencies in the flood plains of coastal or riverine areas. ARTICLE 5-B - PROVISIONS FOR FLOOD HAZARD REDUCTION, SPECIFIC STANDARDS • Article 5-B of said Flood Hazard Prevention Code shall be amended to add the following: ENCLOSURES - new construction and substantial improvements, with fully enclosed areas below the lowest floor that are subject to flooding shall be designed to automatically equalize hydrostatic flood forces on exterior walls by allowing for the entry and exit of floodwaters. Designs for meeting this requirement must either be certified by a registered professional engineer or architect or meet or exceed the following minimum criteria: a. A minimum of two openings having a total net area of not less than one square inch for every square foot of enclosed area subject to flooding r w 0 shall be provided. b. The bottom of all openings shall be no higher than one foot above grade. c. Openings may be equipped with screens, louvers, valves, or other coverings or devices provided that they permit the automatic entry and exit of floodwaters. This Ordinance adopted this day of 1987.
