Article 10: Definitions 254 <br /> Section 10.1: Definitions <br /> describes federal, state or local regulations in any combination thereof, which provide standards for <br /> preventing and reducing flood loss and damage. <br /> Flood Proofing <br /> Any combination of structural and nonstructural additions, changes, or adjustments to structures, which <br /> reduce or eliminate risk of flood damage to real estate or improved real property, water and sanitation <br /> facilities, or structures with their contents. <br /> Flood-resistant material <br /> Any building product, material, component or system, capable of withstanding direct and prolonged <br /> contact (minimum 72 hours) with floodwaters without sustaining damage that requires more than low-cost <br /> cosmetic repair. Any material that is water-soluble or is not resistant to alkali or acid in water, including <br /> normal adhesives for above-grade use, is not flood-resistant. Pressure-treated lumber or naturally decay- <br /> resistant lumbers are acceptable flooring materials. Sheet-type flooring coverings that restrict <br /> evaporation from below and materials that are impervious, but dimensionally unstable are not acceptable. <br /> Materials that absorb or retain water excessively after submergence are not flood-resistant. Please refer <br /> to Technical Bulletin 2, Flood Damage-Resistant Materials Requirements, and available from the FEMA. <br /> Class 4 and 5 materials, referenced therein, are acceptable flood-resistant materials. <br /> Floodway <br /> The channel of a river or other watercourse and the adjacent land areas that must be reserved in order to <br /> discharge the base flood without cumulatively increasing the water surface elevation more than one foot. <br /> This term may also be referred to as "regulatory floodway." <br /> Floodway encroachment analysis <br /> An engineering analysis of the impact that a proposed encroachment into a floodway or non- <br /> encroachment area is expected to have on the floodway boundaries and flood levels during the <br /> occurrence of the base flood discharge. The evaluation shall be prepared by a qualified North Carolina <br /> licensed engineer using standard engineering methods and models. <br /> Flood Zone <br /> A geographical area shown on a Flood Insurance Rate Map that reflects the severity or type of flooding in <br /> the area. <br /> Floor <br /> See "Lowest Floor". <br /> Floor Area Ratio <br /> Floor Area Ratio (FAR) is the maximum floor area permitted for each square foot of land area. <br /> Footcandle <br /> See Outdoor Lighting, Foot-candle. <br /> Forest Plantation <br /> An area of planted trees that may be conifers (pines) or hardwoods. On a plantation, the intended crop <br /> trees are planted rather than naturally regenerated from seed on the site, coppice (sprouting), or seed <br /> that is blown or carried into the site. <br /> Forest Vegetation <br /> The plants of an area which grow together in disturbed or undisturbed conditions in various wooded plant <br /> communities in any combination or trees, saplings, shrubs, vines, and herbaceous plants. This includes <br /> mature and successional forests as well as cutover stands. <br /> Foundry <br /> Orange County, North Carolina—Unified Development Ordinance Page 10-17 <br />
