Have adequate drainage provided to reduce exposure to flood hazards 4. Have BFE data provided if development exceeds either of 50 lots /units or of five acres. Such BFE data shall be adopted by reference per Section 42 -37. (Ord. of 8 -28- 1995, § 5.4, eff. 8 -28 -1995) Sec. 42 -94a. Standards for floodplains with BFE but without established floodways or non - encroachment areas. (5) Along rivers and streams where BFE data area is provided, but neither floodway not non - encroachment areas are identified for a SFHA on the FIRM or in the FIS, no encroachments, including fill, new construction, substantial improvements, or other development, shall be permitted unless certification with supporting technical data by a North Carolina licensed Professional Engineer is provided demonstrating that the cumulative effect of the proposed development, when combined with all other existing and anticipated development, will not increase the water surface elevation of the base flood by more than one foot at any point within Orange County. Sec. 42 -94b. Floodway and non - encroachment areas. Areas designated as floodways or non - encroachment areas are located within the SFHA established in Section 42 -37. The floodways and non - encroachment areas are extremely hazardous areas due to the velocity offloodwaters that have erosion potential and carry debris and potential projectiles. The followingprovisions shall apply to all development within such areas: 1. No encroachments, including fill, new construction, substantial improvements and other (5) developments shall be permitted unless it has been demonstrated through hydrologic and hydraulic analyses, performed according to standard engineering practice, that the proposed encroachment would not result in any increase in the flood levels during the occurrence of the base flood. Such certification and technical data shall be presented to the Floodplain Administrator before issuance of floodplain development permit. 2. If the requirements of Section 42- 94b(1) are adhered to, all development shall comply with all applicable flood hazard reduction provisions of this Ordinance. 3. No manufactured homes shall be permitted, except replacement manufactured homes in an existing manufactured home park or subdivision, provided the following provisions are met: a. The anchoring and elevation standards of Section 42- 92(3); and b. The no encroachment standard of Section 42- 94b(2) is met. Sec. 42 -94c.
