Article 4: Overlay Zoning Districts Section 1.1: Special Flood Hazard Area (SFHA) Orange County, North Carolina – Unified Development Ordinance Page 4-12 (C) Control the alteration of natural floodplains, stream channels, and natural protective barriers, which are involved in the accommodation of flood waters; (D) Control filling, grading, dredging, and all other development, which may increase erosion or flood damage; and (E) Prevent or regulate the construction of flood barriers, which will unnaturally divert floodwaters or which may increase flood hazards to other lands. 4.3.2 Objectives The objectives of this overlay district are to: (A) Protect human life, safety, and health; (B) Minimize expenditure of public money for costly flood control projects; (C) Minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the expense of the general public; (D) Minimize prolonged business losses and interruptions; (E) Minimize damage to public facilities and utilities such as water and gas mains, electric, telephone, cable and other communication facilities, and sewer lines, streets, and bridges located in flood prone areas; (F) Help maintain a stable tax base by providing for the sound use and development of flood prone areas in such a manner as to minimize flood blight areas; and (G) Ensure that potential homebuyers are notified that property is in a Special Flood Hazard Area. 4.3.3 Findings of Fact (A) The flood prone areas within the planning jurisdiction of Orange County are subject to periodic inundation, which results in loss of life, property, health and safety hazards, disruption of commerce and governmental services, extraordinary public expenditures of flood protection and relief, and impairment of the tax base, all of which adversely affect the public health, safety, and general welfare. (B) These flood losses are caused by the cumulative effect of obstructions in floodplains causing increases in flood heights and velocities, and by the occupancy in flood prone areas by uses vulnerable to floods or hazards to other lands, which are inadequately elevated, flood proofed, or otherwise unprotected from flood damages. 4.3.4 Applicability Regulations pertaining to this overlay district shall apply to all SFHAs within the planning jurisdiction of Orange County and within the jurisdiction of any municipality within Orange County whose governing body has duly authorized its application within its municipal, or extraterritorial jurisdictional, boundaries in accordance with North Carolina law. 4.3.5 Basis for Establishment (A) The SFHA are those identified by the FEMA or produced under the Cooperating Technical State agreement between the State of North Carolina and FEMA or Flood Insurance Study (FIS) and its accompanying FIRMs for Orange County dated February 2, 2007, with incorporation of Letters of Map Amendments 07-04-6156R, 08-04-2897A, 08- 04-2898A, 08-04-2899A, and 08-04-2900A, Letters of Map Revision 06-04-BQ22P, 06- 04-C141P, 07-04-6156R, and 08-04-1666P and Summary of Map Amendment #115- CWG (C) dated May 16, 2008, which with accompanying supporting data, including Letters of Map Amendment or Revision and Summary of Map Amendments, are adopted by reference and declared to be a part of this Ordinance. 44
