30 <br />areas due to the velocity of floodwaters that have erosion potential and carry debris and potential <br />projectiles. The following provisions shall apply to all development within such areas: <br />1. No encroachments, including fill, new construction, substantial improvements and other <br />developments shall be permitted unless it has been demonstrated through hydrologic and <br />hydraulic analyses, performed according to standard engineering practice, that the proposed <br />encroachment would not result in any increase in the flood levels during the occurrence of <br />the base flood. Such certification and technical data shall be presented to the Floodplain <br />Administrator before issuance of floodplain development permit. <br />2. If the requirements of Section 42- 94b(1) are adhered to, all development shall comply with <br />all applicable flood hazard reduction provisions of this Ordinance. <br />3. No manufactured homes shall be permitted, except replacement manufactured homes in an <br />existing manufactured home park or subdivision, provided the following provisions are met: <br />a. The anchoring and elevation standards of Section 42- 92(3); and <br />b. The no encroachment standard of Section 42- 94b(2) is met. <br />(Ord. of 10 -03 -2005, eff. 10 -03 -2005) <br />Sec. 42 -94c. Standards for Floodplains without Established Base Flood Elevations. <br />Within the SFHAs established in Section 42 -37, where no BFE data has been provided, the <br />following provisions shall apply: <br />1. No encroachments, including fill, new construction, substantial improvements or new <br />development shall be permitted within a distance of twenty feet each side from top of bank or <br />five times the width of the stream whichever is greater, unless certification with supporting <br />technical data by a North Carolina licensed Professional Engineer is provided demonstrating <br />that such encroachments shall not result in any increase in flood levels during the occurrence <br />of the base flood discharge. <br />2. If the requirements of Section 42 -94(1) are adhered to and BFE data are available from other <br />sources, all new construction and substantial improvements within such areas shall also <br />comply with all applicable provisions of this Ordinance and shall be elevated or flood <br />proofed according to elevations established according to Section 42- 69(11 /12). When BFE <br />data are not available from a federal, state, or other source, the reference level, including <br />basement, shall be elevated at least two (2') feet above the HAG. <br />(Ord. of 10 -03 -2005, eff. 10 -03 -2005) <br />Sec. 42 -95. Standards for areas of shallow flooding (AO zones). <br />Located within the SFHAs established in Section 42 -37, are areas designated as shallow <br />flooding areas. These areas have special flood hazards associated with base flood depths of one (1) to <br />three (3) feet where a clearly defined channel does not exist and where the path of flooding is <br />unpredictable and indeterminate. The following provisions shall apply within such areas: <br />
