05/12/2005 Sec. 42-94. Subdivisions, manufactured home parks, and major developments. All subdivisions manufactured home par and maior development proposals located within SFHAs shall: 33 1 n„ w,,• ~~~~~ ~,,,,r Be consistent with the need to minimize flood damage. 2 n n ,.~~:____._.._r r -~~~ ~w~n Have public utilities and facilities such as sewer, gas, electric, cable, and water systems located and constructed to minimize flood damage. 3 n„ wa• ~~~ ~~~» Have adequate drainage provided to reduce exposure to flood hazards 4. Have BFE datashall-be provided if development x."~:e='.°-r exceeds either t~ `'__z-n-hse of 50 lots/units or five acres. Such SFE 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. 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 includini: fill new construction substantial improvements, or other_development, shall be permitted unless certification with supporting technical data by a North Carolina licensed Professional Eneineer is provided demonstrative that the cumulative effect of the proposed development when combined with all other existine and anttcrpated development, will not increase the water surface elevation of the base flood by more than one foot at anygomt within Orange County. Sec. 42-94b. Floodway and non-encroachment areas. Areas desi Hated as floodwa s 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 of floodwaters that have erosron potential and carry debris and potential projectiles The following provisions shall apply to all development wrthm such areas: 1. No encroachments including fill new construction substantial improvements and other 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 durin the occurrence of the base flood. Such certt£-catton and technical data shall be presented to the Floodplain Administrator before issuance of floodplain development permit. :'. r.p ~fi~i Innuupf ~ <~ni iI~II~u?;qu rL,:~t~i ~.I1nadL.~u~mcd:~
