1 1 C n 1 11. Cantilevered portions of structures, provided that foundation and supports are located outside the floodway and non-encroachment area and the underside of the cantilevered portion is at least two feet above base flood elevation. e. Prohibited uses. Storage or processing of materials that are flammable, corrosive, toxic, or explosive, or which could otherwise be injurious to human, animal or plant life in time of flood is prohibited in the floodway and non-encroachment area. (9) Floodway and non-encroachment area fringe permitted uses. The following uses shall be permitted within the floodway and non-encroachment area fringe to the extent that they are otherwise permitted by this article and the zoning ordinance. a. Uses permitted below flood protection elevation: 1. Any use as permitted and regulated in the floodway and non-encroachment area. 2. Fill material graded to drain, provided such is protected against erosion. Any fill material on which a structure is to be located shall be extended at grade ten feet beyond the limits of the structure foundation, and shall have a side slope no steeper than two feet horizontal to one foot vertical. All material used as fill within the floodway and non-encroachment area fringe must be derived from adjacent floodway and non-encroachment area fringe and the same deeded parcel as that area being filled. The net result of borrow and fill within the floodway and non- encroachment area fringe area shall constitute no net loss to the flood storage capacity of the floodway and non-encroachment area fringe. A professional engineer must certify that no net loss of storage will occur as a result of the fill activity. 3. Structure foundations and supports, provided such are firmly anchored to prevent flotation. b. Uses permitted above flood protection elevation: 1. Any residential or nonresidential use permitted by this article and the zoning ordinance provided that the lowest flood elevation of any structure is located two feet or more above base flood elevation. Heating and electrical equipment installed below flood protection elevation shall be flood-proofed. 2. Any nonresidential use permitted by this article and the zoning ordinance provided that all portions of the structure are elevated or flood-proofed, as provided in this division, to an elevation at least two feet above base flood elevation. 3. Heating and electrical equipment installed below flood protection elevation shall be flood- proofed. Nonresidential structures may floodproof this equipment if placed below the base flood elevation, but the floodproofing must be certified by a professional engineer or architect registered in North Carolina. (c) Prohibited uses. Uses that are prohibited below the flood protection elevation are the storage or processing of materials that are flammable, corrosive, toxic, or explosive or which could otherwise be injurious to human, animal or plant life in time of flood. (Ord. of 2-16-87, art. 5, § B; Ord. of 10-17-94, art. 5, § B; Ord. No. 1998-10, 6-15-98) Sec. 38-78. Standards for streams without established base flood elevations and/or floodway and non-encroachment areas. Located within the areas of special flood hazard established in section 38-32, are small streams where no base flood data has been provided or where no floodway and non- encroachment areas have been identified. The following provisions apply within such areas: (1) No encroachments, including fill, new construction, substantial improvements of new development or new development shall be permitted within a distance of the stream bank equal to the setback established by the Coastal Area Management Act (CAMA) regulations. Where no setback is established by CAMA regulations, the area of no encroachment shall be 20 feet each side from top of bank, unless certification with supporting technical data by a Item# 11 Attachment number 2 !7 7 Page 126 of 185
