(A) Lands to which this chapter applies. This suchapter shall apply to all Special Flood Hazard Areas within the jurisdiction, including Extra-Territorial Jurisdictions (ETJ) if applicable, of the Town of Beech Mountain and within the jurisdiction of any other community whose governing body agrees, by resolution, to such applicability.
(B) Basis for establishing the special flood hazard areas.
(1) FEMA. The Special Flood Hazard Areas are those identified by the Federal Emergency Management Agency (FEMA) or produced under the Cooperating Technical State (CTS) agreement between the State of North Carolina and FEMA in its Flood Hazard Boundary Map (FHBM) or Flood Insurance Study (FIS) and its accompanying flood maps such as the Flood Insurance Rate Map(s) (FIRM) and/or the Flood Boundary Floodway Map(s) (FBFM), for Watauga County, panel #'s 150e, 151e and 153e dated September 21, 1998, which with accompanying supporting data, and any revision thereto, including Letters of Map Amendment or Revision, are adopted by reference and declared to be a part of this subchapter. The Special Flood Hazard Areas also include those defined through standard engineering analysis for private developments or by governmental agencies, but which have not yet been incorporated in the FIRM. This includes, but is not limited to, detailed flood data:
(a) Generated as a requirement of § 154.328(C)(11) and (12) of this subchapter;
(b) Preliminary FIRMs where more stringent than the effective FIRM; or
(c) Post-disaster Flood Recovery Maps.
(2) Municipal. In addition, upon annexation to the Town of Beech Mountain or inclusion in the Extra-Territorial Jurisdiction (ETJ), the Special Flood Hazard Areas identified by the Federal Emergency Management Agency (FEMA) and/or produced under the Cooperating Technical State agreement between the State of North Carolina and FEMA as stated above for the Unincorporated Areas of Avery and Watauga Counties, with accompanying maps and other supporting data, and any revision thereto, are adopted by reference and declared to be a part of this subchapter.
(C) Establishment of floodplain development permit. A Floodplain Development Permit shall be required in conformance with the provisions of this subchapter prior to the commencement of any development activities within Special Flood Hazard Areas as determined in § 154.327(B) above.
(D) Compliance. No structure or land shall hereafter be located, extended, converted, altered, or developed in any way without full compliance with the terms of this suchapter and other applicable regulations.
(E) Abrogation and greater restrictions. This suchapter is not intended to repeal, abrogate, or impair any existing easements, covenants, or deed restrictions. However, where this subchapter and another conflict or overlap, whichever imposes the more stringent restrictions shall prevail.
(F) Interpretation. In the interpretation and application of this chapter, all provisions shall be:
(1) Considered as minimum requirements;
(2) Liberally construed in favor of the governing body; and
(3) Deemed neither to limit nor repeal any other powers granted under state statutes.
(G) Warning and disclaimer of liability. The degree of flood protection required by this subchapter is considered reasonable for regulatory purposes and is based on scientific and engineering consideration. Larger floods can and will occur on rare occasions. Actual flood heights may be increased by man-made or natural causes. This subchapter does not imply that land outside the Special Flood Hazard Areas or uses permitted within such areas will be free from flooding or flood damages. This subchapter shall not create liability on the part of the Town of Beech Mountain or by any officer or employee thereof for any flood damages that result from reliance on this subchapter or any administrative decision lawfully made hereunder.
(H) Penalties for violation. Violation of the provisions of this subchapter or failure to comply with any of its requirements, including violation of conditions and safeguards established in connection with grants of variance or special exceptions, shall constitute a misdemeanor. Any person who violates this subchapter or fails to comply with any of its requirements shall, upon conviction thereof, be fined not more than $50 or imprisoned for not more than 30 days, or both. Each day such violation continues shall be considered a separate offense. Nothing herein contained shall prevent the Town of Beech Mountain from taking such other lawful action as is necessary to prevent or remedy any violation.

(2) Any person aggrieved by the decision of the appeal board may appeal such decision to the Court, as provided in G.S. Ch. 7A.
(3) Variances may be issued for the repair or rehabilitation of historic structures upon the determination that the proposed repair or rehabilitation will not preclude the structure's continued designation as a historic structure and the variance is the minimum necessary to preserve the historic character and design of the structure.
(4) In passing upon variances, the appeal board shall consider all technical evaluations, all relevant factors, all standards specified in other sections of this subchapter, and:
(a) The danger that materials may be swept onto other lands to the injury of others;
(b) The danger to life and property due to flooding or erosion damage;
(c) The susceptibility of the proposed facility and its contents to flood damage and the effect of such damage on the individual owner;
(d) The importance of the services provided by the proposed facility to the community;
(e) The necessity to the facility of a waterfront location, where applicable;
(f) The availability of alternative locations, not subject to flooding or erosion damage, for the proposed use;
(g) The compatibility of the proposed use with existing and anticipated development;
(h) The relationship of the proposed use to the comprehensive plan and floodplain management program for that area;
(i) The safety of access to the property in times of flood for ordinary and emergency vehicles;
(j) The expected heights, velocity, duration, rate of rise, and sediment transport of the flood waters and the effects of wave action, if applicable, expected at the site; and
(k) The costs of providing governmental services during and after flood conditions including maintenance and repair of public utilities and facilities such as sewer, gas, electrical and water systems, and streets and bridges.
(5) A written report addressing each of the above factors shall be submitted with the application for a variance.
(6) Upon consideration of the factors listed above and the purposes of this subchapter, the appeal board may attach such conditions to the granting of variances as it deems necessary to further the purposes of this subchapter.
(7) Variances shall not be issued within any designated floodway or non-encroachment area if any increase in flood levels during the base flood discharge would result.
(8) Conditions for variances:
(a) Variances may not be issued when the variance will make the structure in violation of other federal, state, or local laws, regulations, or ordinances.
(b) Variances shall only be issued upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief.
(c) Variances shall only be issued upon:
1. A showing of good and sufficient cause;
2. A determination that failure to grant the variance would result in exceptional hardship; and
3. A determination that the granting of a variance will not result in increased flood heights, additional threats to public safety, or extraordinary public expense, create nuisance, cause fraud on or victimization of the public, or conflict with existing local laws or ordinances.
(d) Any applicant to whom a variance is granted shall be given written notice specifying the difference between the Base Flood Elevation (BFE) and the elevation to which the structure is to be built and a written statement that the cost of flood insurance will be commensurate with the increased risk resulting from the reduced reference level elevation. Such notification shall be maintained with a record of all variance actions.
(e) The Floodplain Administrator shall maintain the records of all appeal actions and report any variances to the Federal Emergency Management Agency and the State of North Carolina upon request.

(D) Standards for floodplains without established Base Flood Elevations. Within the Special Flood Hazard Areas established in § 154.328(B), where no Base Flood Elevation (BFE) data has been provided, the following provisions shall apply:
(1) No encroachments, including fill, new construction, substantial improvements or new development shall be permitted within a distance of 20 feet each side from top of bank or five times the width of the stream whichever is greater, unless certification with supporting technical data by a registered professional engineer is provided demonstrating that such encroachments shall not result in any increase in flood levels during the occurrence of the base flood discharge.
(2) If § 154.329(C)(1) is satisfied and Base Flood Elevation (BFE) data is available from other sources, all new construction and substantial improvements within such areas shall also comply with all applicable provisions of this subchapter and shall be elevated or floodproofed in accordance with elevations established in accordance with § 154.328(C)(11) and (12). When Base Flood Elevation (BFE) data is not available from a federal, state, or other source, the reference level, including basement, shall be elevated at least two feet above the highest adjacent grade.
(E) Standards for floodplains with BFE but without established floodways or non-encroachment areas. Along rivers and streams where Base Flood Elevation (BFE) data is provided but neither floodway nor non-encroachment areas are identified for a Special Flood Hazard Area 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 registered 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 more than one foot at any point within the community.
(F) Floodways and non-encroachment areas. Located within the Special Flood Hazard Areas established in § 154.327(B) are areas designated as floodways or non-encroachment areas. The floodways and non-encroachment areas are extremely hazardous areas due to the velocity of floodwaters that have erosion potential and carry debris and potential projectiles. The following provisions shall apply to all development within 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 in accordance with 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 prior to issuance of floodplain development permit.
(2) If § 154.329(F)(1) is satisfied, all development shall comply with all applicable flood hazard reduction provisions of this subchapter.
(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 the elevation standards of § 154.329(B)(3); and
(b) The no encroachment standards of § 154.329(F)(1) are met.
(G) Standards for areas of shallow flooding (AO Zones). Located within the Special Flood Hazard Areas established in § 154.327(B), are areas designated as shallow flooding areas. These areas have special flood hazards associated with base flood depths of one to three feet where a clearly defined channel does not exist and where the path of flooding is unpredictable and indeterminate. The following provisions shall apply within such areas:
(1) All new construction and substantial improvements of all structures shall have the lowest floor, including basement, elevated to the depth number specified on the Flood Insurance Rate Map (FIRM), in feet, above the highest adjacent grade. If no depth number is specified, the lowest floor, including basement, shall be elevated at least to the regulatory flood protection elevation as defined for the Special Flood Hazard Areas where no BFE has been established.
(2) All new construction and substantial improvements of non-residential structures shall have the option to, in lieu of elevation, be completely floodproofed together with attendant utilities and sanitary facilities to or above that level so that any space below that level is watertight with walls substantially impermeable to the passage of water and with structural components having the capability of resisting hydrostatic and hydrodynamic loads and effects of buoyancy. Certification is required as per § 154.328(B)(3) and § 154.329(B)(2).

(A) Effect upon outstanding building permits. Nothing herein contained shall require any change in the plans, construction, size or designated use of any development or any part thereof for which a floodplain development permit has been granted by the floodplain administrator or his or her authorized agents before the time of passage of this subchapter; provided, however, that when construction is not begun under such outstanding permit within a period of six months subsequent to passage of this subchapter or any revision thereto, construction or use shall be in conformity with the provisions of this subchapter.
(B) Effective date. This suchapter shall be effective upon adoption.
