(a) Application for a building or grading permit. An application for a building or grading permit for land located in a floodplain district shall contain or be accompanied by the following information:
(1) a demonstration that new structures cannot be located outside the floodplain and that encroachments into the floodplain are minimized;
(2) the elevations of the proposed final grading; the lowest floor levels; the floor area below the lowest floor; the existing ground contours; the 100-year flood elevation; and the high-velocity water and wave action elevation, including its relation to a stream channel, shoreline, floodplain district, and floodplain subdistrict, as certified by a design professional;
(3) the method of elevating a proposed structure, including details of proposed fills, pile structures, retaining walls, foundations, and erosion protection measures, as prepared by a design professional;
(4) the methods used to protect electrical, plumbing, and mechanical systems and utilities from flooding;
(5) for a substantial improvement to an existing structure, the State's assessed value or, at the developer's option, a current "as is" appraisal performed by a professional real estate appraiser of the market value of the structure, excluding land value;
(6) for a relocation, alteration, or modification of all or part of a watercourse or stream, evidence that notice has been sent as required by § 16-2-204 and an engineering study prepared by a design professional that analyzes all reasonable alternatives and fully evaluates the effects of the construction, using applicable 100-year flood and floodway data prepared by FEMA, and that includes a certification that the flood-carrying capacity within the watercourse or stream will not be affected;
(7) an acknowledgment that flood insurance for a structure not elevated or floodproofed in conformance with this title may be available only at prohibitive rates or not at all and that construction below the level of the 100-year flood increases risk to life and property; and
(8) for accessory structures, a statement on the building plans that reads as follows: "No conversion of this area to habitable space is to occur unless the lowest floor is elevated to one foot above the 100-year flood elevation. At this site the 100-year flood elevation is ___________."
(b) Application for subdivision. An application for subdivision on land that includes areas within a floodplain district shall include:
(1) a delineation of the 100-year flood elevation if determined by the flood insurance study or watershed studies conducted by the County; and
(2) if the 100-year floodplain elevation has not been determined, the developer shall determine the 100-year floodplain elevation in accordance with the County Procedures Manual and delineate the elevation on the proposed plans. Plans shall be certified by a design professional.
