               Development and land disturbing activity in floodway and floodway fringe are regulated
               by the county zoning ordinance, section 11, natural resource protection standards
               in addition to the Durham, North Carolina Flood Damage Protection Ordinance. Where
               development is allowed by the county zoning ordinance, the following provisions are

                  Fill material shall be used for all new construction and substantial improvements
                  to create an elevation that is two feet above base flood elevation. The fill material
                  shall be required to extend for a distance of 40 feet from the exterior walls of a
                  building. Where the distance to the property line is less than 40 feet, the fill shall
                  extend to the property line. The required fill material distance shall include a sloped
                  edge with a maximum 3:1 slope (for example, for a fill three feet deep: 31 feet of
                  flat fill + nine feet of sloped fill) or a retaining wall in lieu of the slope (for
                  example, a side yard of flat fill and a retaining wall). Residential accessory structures
