15 The name of a subdivision shall not duplicate nor closely approximate the name of an existing subdivision within the County or any municipality within the County. SECTION 4.5 FLOOD DAMAGE PREVENTION Lots that are subject to flooding shall not be established in subdivisions for the purpose of creating building sites except as herein provided and in accor- dance with the Flood Damage Prevention Ordinance of Cabarrus County: 1. If there is any water course of any type running through or within 150 feet of the property proposed for subdivision, the prospective subdivider shall furnish reasonable evidence to the Planning Board that lots within the subdivision will not be flooded. 2. The prospective subdivider shall make a determination of the crest elevation of a flood of 100-year probable frequency in accordance with generally accepted engineering practice. This determination must reflect the actual conditions imposed by the completed subdivision, and must give due consideration to the effects of urbanization and obstructions. 3. No proposed building lot shown that is wholly subject to flooding shall be approved. 4. No proposed building lot that is partially subject to flooding shall be approved, unless there is established on the lot plan a line repre- senting an actual contour at an elevation one (1) foot above the 100-year flood. Such line shall be known and identified on the lot plan or the "building restriction flood line". No filling shall be permitted in the 100 year flood area. Ail buildings or structures designed or intended for use shall be located on such a lot so that the lowest usable and functional part of the structure shall not be below the elevation of building restriction flood line. Usable and functional part of the structure is defined as being inclusive of living areas, basements, sunken dens, utility rooms, attached carports and mechanical appurtenances such as furnaces, air conditioners, water pumps, electrical conduits and wiring but shall not include water lines or sanitary sewer traps, piping and cleanouts provided openings serving the structure are above the building restriction flood line. Where only a portion of a proposed building lot is subject to flooding, such lot may be approved only if they will be available for building, a usable lot area of not less than 1,200 square feet. The usable lot area shall be determined by deducting from the total lot area the area of the setback required by an applicable zoning district regulation and any remaining area of the lot lying below the building restriction flood line. 5. During the construction, preparation, arrangement and installation of subdivision improvements, and facilities in subdivisions located at or along a stream bed, the developer shall maintain the stream bed of each stream, creek or backwash channel contiguous to the subdivision in an unobstructed state. The developer shall also remove from the channel and banks of the stream all debris, logs, timber, junk and other accumulations of a nature that would, in time of flood, clog or damn the passage of waters in their downstream course. Installation of appropriately sized storm water drains, culverts or bridges shall not be construed as obstructions in the streams. SECTION 4.6 SEDIMENTATION POLLUTION CONTROL Upon approval of the preliminary plat the Planning Staff shall notify the North Carolina Department of Natural Resources and Community Development of such approval. Ail applicable requirements of the North Carolina Sedimentation Pollution Control Act, General Statute l13A as amended shall be complied with by the developer. The subdivider is required to submit to the Planning Staff evidence of a state approved erosion and sedimentation control plan before any construction or grading commences, else preliminary plat is null and void and
