Sec. 7-11-6. Traffic impact analysis.
(a)   Purpose. The purpose of this section is to ensure that applicants for new construction, additions and/or expansions to existing structures, and/or changes of use consider and mitigate the impact of the development on the existing and/or proposed roadway system. While the city and the State of North Carolina recognize their responsibility to build and maintain a public transportation system, the project applicants may need to assist in improving transportation facilities in order to maintain the existing level of service by accommodating additional traffic generated by the development. These transportation facilities involve pedestrian, non-motorized vehicular traffic and motorized vehicular traffic. The city's traffic engineering division will provide any necessary assistance in the preliminary review of these requirements.
(b)   Traffic impact analysis required. All proposals for new construction, additions and/or expansions to existing structures, and/or changes of use which will result in total peak hour trips equal to or greater than 100 peak hour trips using trip generation rates from the most recent edition of the Trip Generation Manual published by the Institute of Transportation Engineers shall include an analysis of the traffic to be generated.

Sec. 7-11-7. Flexible development standards.
(a)   Purpose. The purpose of this section is to provide the planning and development director, design review boards, and city council, as applicable, with the authority to allow deviations from the development standards for setbacks, front and corner side setbacks, lot area and dimension, number of parking spaces, signage, open space, landscaping, height, and building floor area set forth in this chapter provided that certain conditions exist. The intent of this section is to promote the orderly and efficient development of property.
(b)   Approval of flexible development standards. Regardless of the minimum development standards otherwise required in this Code, the planning and development director shall administer the following flexible development standards for the purpose of facilitating the orderly development and redevelopment of property within the City of Asheville. Determination of the applicability of flexible development standards shall be made by the planning and development director, design review boards, and city council, as applicable and as provided in this section. The planning and development director, design review boards, and city council may place conditions on an approval to assure that the circumstances which warranted the application of the flexible development standards are maintained. Decisions by the planning and development director shall be in writing and may be appealed to the board of adjustment by following the procedures for such appeals provided in section 7-6-2 of this chapter.
(c)   Flexible development standards permitted. The cumulative total of any flexible development standard applied to a property by category or location shall not exceed the maximums set forth in this section. The planning and development director shall maintain appropriate records to insure compliance with this provision.
(1)   Setbacks. The planning and development director is authorized to approve requests that deviate from required setbacks set forth in article VIII of this chapter as follows:
a.   Building additions - all zoning districts. Setbacks may be adjusted when flexibility is needed to accommodate a building addition that is less than 50 percent of the pre-existing gross floor area. In these instances, a deviation of ten percent or 24 inches, whichever is greater, may be granted upon determining that one or more of the following conditions exists:
i.   The lot does not meet the dimensional standards established for the zoning district in which it is located.
ii.   The structure is physically in line with an existing, legally established wall or walls of a principal structure already within the minimum setback area.
iii.   The part of the proposed structure that would encroach into the minimum setback area is less than 50 percent of the width of the affected building facade(s), provided the part of the structure that would encroach into a front setback shall either be open, unheated space (such as a porch or screen room) or not subject to occupancy (such as a chimney).
iv.   The part of the proposed structure that encroaches into the minimum setback area is necessitated by a life-safety code, flood hazard reduction, Americans with Disabilities Act standard, or other public safety code requirements.
b.   Structures located in local historic districts and local historic landmarks. Setbacks may be adjusted for structures undergoing design review when flexibility is needed in order to comply with design standards. In these instances setbacks may be adjusted as follows:
i.   Primary structures. Setbacks may be adjusted up to ten percent or 24 inches, whichever is greater.
ii.   Accessory structures. Side and rear setbacks may be adjusted up to 36 inches.
(2)   Parking garages and parking lots. Except for parking required for residential development of less than five units, the planning and development director is authorized to approve parking garages and parking lots in connection with a permitted use that has up to 25 percent less than the required number of spaces set forth in article XI of this chapter upon determining that one or more of the following conditions exists:
a.   The applicant is proposing an adaptive reuse that does not expand the pre-existing floor area of an existing structure with a permitted use.
b.   The applicant is constructing an addition to an existing structure or site and sufficient new parking will be provided to accommodate the additional square footage without reducing the amount of parking serving the existing structure or site prior to the addition.
c.   The proposed parking lot or garage will allow the preservation of an existing aquatic buffer or floodway.
d.   The proposed parking lot or garage will accommodate a tree canopy preservation area where the entirety of the requirement is met by preserving existing canopy.
These reductions may not be used in conjunction with reductions offered elsewhere in this chapter.
(3)   Variances. No variances shall be allowed under article VI of this chapter with regard to deviations from development standards that have been approved pursuant to this section of the city Code nor shall any deviations from these development standards make void or otherwise modify any variance decision by the board of adjustment.

Sec. 7-11-8. Sidewalk requirements.
(a)   Purpose. The purposes of this section are to insure that adequate provision of transportation and other public requirements, the promotion of health, safety and the general welfare and the coordination of streets and other public facilities are considered in the development and use of property and that development and use of property are done in accordance with an adopted City of Asheville (herein "city"), transportation or corridor plan, including but not limited to such plans as the Transportation Improvement Program (TIP), greenway, neighborhood, small area, and pedestrian thoroughfare plans. The city council hereby incorporates by reference as if set forth in full herein the findings of the city's pedestrian thoroughfare plan and further finds and declares that the construction of sidewalks advances those interests of the city and, in order to accomplish those purposes, this section sets out requirements for the construction of sidewalks and, where a developer requests it and certain conditions exist, for the payment of a fee in lieu of the requirement for construction of sidewalks.
(b)   Guidelines for requiring sidewalks. Sidewalks shall be required for all new construction and for renovations, additions and/or expansions to existing structures which fall into one or more of the following categories:
(1)   All new single-family residential development which consists of 20 or more single-family homes (see "new development" explication below);
(2)   AH new multi-family residential development, except for the construction of less than ten units (see "new development" explication below);
(3)   All new office, institutional, commercial, and industrial development (see "new development" explication below);
(4)   All existing office, institutional, commercial, and industrial development additions or expansions to structures where the expansion results in an increase of more than 75 percent value of the structure as defined in section 7-11-1 of this chapter.
(5)   All new streets, improved streets or extension to streets.
"New development" shall be interpreted to include all new construction in addition to the use of a building or property where the use has, ceased for a period of more than 180 days. See also subsections 7-17-5(c) and 7-17-5(d) concerning "overcoming presumption of cessation of use". This does not include minor additions or expansions that do not meet the city's threshold standards identified in subsection (3) above.
(c)   Additional conditions for requiring sidewalks. Notwithstanding (b) above, the following findings must be made prior to the city engineer/designee requiring the construction of a new sidewalk or a "fee in lieu of constructing a sidewalk for an applicable project. One or more of the following conditions must be met, as determined by the city engineer/designee.
(1)   The applicable project area, including the street frontage, is identified as a needed pedestrian linkage within an adopted city transportation or corridor plan, including but not limited to such plans as the Transportation Improvement Program (TIP), greenway, neighborhood, small area, and pedestrian thoroughfare plans.
(2)   The current or projected (within five years) average daily traffic count (ADT) for the street is 300 vehicles per day or more as determined by the city traffic engineer. Traffic generated from the applicable project or any additions to the applicable project will be included in calculating the ADT for this condition.
In the event that the sidewalk is not required, the developer must provide a recorded easement, if necessary, for the future development of the sidewalk. The developer wherever practical shall grade for the future development of a sidewalk.
(d)   Public and private streets. Sidewalks shall be constructed along all public and private street frontages that meet the requirements of section 7-11-8(c) of the lot for which the development is proposed.
All sidewalks shall be constructed in accordance with the standards set forth in the city's Standard Specifications and Details Manual.
(e)   Fee in lieu of construction. Where a new sidewalk is required to be constructed, a fee in lieu of that sidewalk may be paid if one or more of the following conditions apply:
(1)   The sidewalk is proposed to be constructed within an existing right-of-way where sufficient right-of- way or easement width does not exist or cannot be dedicated to build the sidewalk without reducing existing transportation facilities such as travel lanes, on-street parking, bike lanes, and the adaptive reuse or preservation of an existing building or structure prevents extending the sidewalk onto private property. In these instances, compliance to the maximum extent practicable is required and a fee is paid for the balance of sidewalk not constructed.
(2)   The sidewalk is a part of a publicly funded project that includes sidewalks and construction is scheduled to begin within two years of permitting. In this case, the developer would pay the fee based on the public agency's design.
(3)   The total project costs are less than $100,000.00 and the cost of the construction of the sidewalk would exceed 15 percent of the total cost of the approved project.
(4)   The traffic volumes on an existing road, including any added trips expected as a result of the project, do not exceed 500 vehicles per day and the required sidewalk is more than 1,320 feet (one-fourth mile) from an existing sidewalk, measured from the closest points along the road frontage.
(5)   When the sidewalk would require the relocation of multiple public utility facilities or structures.
(6)   The sidewalk would be located in a floodway and a no rise certification can not be obtained and a CLOMR cannot be approved without the requirement of purchasing additional affected properties.
(7)   The sidewalk would require construction and/or grading to occur on adjacent property to connect to future sidewalk and where there is no right-of-way or easement available. In these instances, compliance to the maximum extent practicable is required and a fee is paid for the balance of sidewalk not constructed. Additionally, an easement sufficient to provide future connections shall be provided.
The fee shall be based on the amounts identified in the city's Fees and Charges Manual and may be prorated based on partial compliance. In no case shall the fee in lieu of constructing the sidewalk exceed 15 percent of the total cost of the approved project. The total cost of the project shall include all construction costs associated with the improvement as approved by the city.
In the event that a fee in lieu of constructing a sidewalk is approved, the developer must provide a recorded easement if necessary for the future development of the sidewalk. All fees shall be paid prior to the issuance of the zoning permit and shall not transfer to future projects on the same property.
The developer wherever practical shall grade for the future development of a sidewalk.
(f)   Use of fees. All fees collected by the city pursuant to these provisions shall be accounted for separately from other monies, shall be expended only for the construction or rehabilitation of sidewalks or other pedestrian improvements in the city.
(Ord. No. 2664, § 1(a), 2-8-00; Ord. No. 2904, § 1(a), 3-12-02; Ord. No. 3417, § 1(e), 11-28-06; Ord. No. 3791, §§ 1c, d, 9-22-09; Ord. No. 3816, § 1, 12-15-09; Ord. No. 4424, § 1a, 6-9-15; Ord. No. 4361, § 1jj, 3-23-21)
Sec. 7-11-9. Emergency wireless communications.
(a)   Purpose. The purpose of this section is to ensure that buildings and structures shall not interfere with the city's communication network. Developments shall be modified to accommodate the needs of the city's communications network, to eliminate any interference a development would create or otherwise accommodate the needs of the city's communication network within the development proposal. Adequate provisions shall be made for a radio signal booster system which will correct for a reduction in the radio signal to a level below that required to assure the 95 percent area coverage reliability needed for public safety communications.
(b)   Radio signal booster system required. Except as otherwise provided no person shall maintain, own, erect, or construct, any building or structure or any part thereof, or cause the same to be done which fails to support adequate radio coverage for public safety entities, including, but not limited to, firefighters, emergency medical services and police officers. The following structures are exempt from these requirements:
(1)   Single-family residential buildings; any building constructed of wood frame; any building 25 feet high or less; as long as none of the aforementioned buildings make primary use of metal on concrete construction or contain below grade storage or parking areas. For purposes of this section, parking structures are included in the definition of buildings, and stair shafts are included in the definition of all parts of a building, but elevators may be excluded.
(2)   Buildings constructed prior to the effective date of this section (February 12, 2008) shall be required to comply with public safety radio coverage provisions of this section. However, should exempted structures undergo renovation or modification where the cost of the renovation or modification exceeds 75 percent of the appraised value of the structure this exemption shall not apply.
(c)   Easements. The city may require an easement to utilize the roof for communications infrastructure components to support current and future public safety communication needs. This includes, but is not limited to a 12 feet × 25 feet rooftop area for; antennas, base stations, UPS power supplies, and microwave dish antennas. The building owners shall provide a secure climate controlled environment, no less than ten feet × 20 feet × ten feet, suitable for sensitive electronic equipment. This room shall be located within the top floor of roof area to allow for less than 100-foot cable runs to the antenna locations. Power for the equipment in this room shall be fed from the building emergency generator. Additional construction specifications will be made available as required.
(d)   Specifications. All emergency wireless communications shall be constructed in accordance with the standards set forth in the City of Asheville Standards and Specifications Manual.
(e)   Alternative standards. Based on sound telecommunication engineering practices, the information technology director or his designee may approve alternative standards that are equal to or better than those set forth in this chapter and in the City of Asheville Standards and Specifications Manual.

Direct glare. Glare resulting from high luminances or insufficiently shielded light sources in the field of view. It is usually associated with bright areas, such as luminaires, ceilings, and windows that are outside the visual task or region being viewed. A direct glare source can also affect performance by distracting attention.
Directional lighting. Lighting provided on the workplane or on an object. Light that is predominantly from a preferred direction.
Fixture. See luminaire.
Flood lamp. A form of lighting designed to direct its output in a specific direction with a reflector formed from the glass envelope of the lamp itself. Such lamps are so designated by the manufacturers and are typically used in residential outdoor area lighting.
Flood light. A form of lighting designed to direct its output in a diffuse, more or less specific direction, with reflecting or refracting elements located external to the lamp. These lights are prohibited in the City of Asheville.
Footcandle (FC). A quantitative unit measuring the amount of light (illumination) falling onto a given point. One footcandle equals one lumen per square foot.
Fully shielded. A light fixture constructed, installed and maintained in such a manner that all light emitted from the fixture, either directly from the lamp or a diffusing element, or indirectly by reflection or refraction from any part of the fixture, is projected below the horizontal plane through the fixtures lowest light emitting part.
Glare. The effect produced by a light source within the visual field that is sufficiently brighter than the level to which the eyes are adapted, to cause annoyance, discomfort, or loss of visual performance and ability.

Uplight. The portion of luminous flux (light) from a luminaire emitted at angles above the horizontal.
Vehicular canopy. A roofed, open, drive-through structure designed to provide temporary shelter for vehicles and their occupants while making use of a business' services.
Vertical footcandles. A quantity of illumination (footcandle(s)) at a given point that is measured or calculated at a specified height in a plane perpendicular to the line of sight when looking at the brightest light source in the field of view.
Very low luminosity lighting. Temporary, seasonal, or permanent lighting fixtures whose luminosity does not exceed 15 lumens. See also low luminosity lighting.
Wall-mounted fixture. A luminaire/fixture that is typically mounted on or attached to a wall, column or building surface.
Wall pack. A type of light luminaire/fixture typically flush-mounted on a vertical wall surface.
Wide-body refractive globe. A translucent lamp enclosure used with some outdoor fixtures to provide a decorative look (including but not limited to acorn- and carriage light-style fixtures). "Wide-body" refers to a wider than average size globe (greater than 15.75 inches in diameter). "Refractive" refers to the redirection (bending) of the light as it goes through the lens, rendering the light fixture more effective. Wide-body refractive globes are intended to soften and spread the light being distributed from the light source thereby reducing direct glare.
(c)   Light measurement technique. Light level measurements shall be made at the property line of the property upon which light to be measured is being generated. If measurement on private property is not possible or practical, light level measurements may be made at the boundary of the public street right-of-way that adjoins the property of the complainant or at any other location on the property of the complainant. Measurements shall be made at finished grade (ground level), with the light-registering portion of the meter held parallel to the ground pointing up. The meter shall have cosine and color correction and have an accuracy tolerance of no greater than plus or minus five percent. Measurements shall be taken with a light meter that has been calibrated within two years. Light levels are specified, calculated and measured in footcandles. All footcandle values below are maintained footcandles.

ARTICLE XII. ENVIRONMENTAL PROTECTION STANDARDS
Sec. 7-12-1. Flood protection.
(a)   Authority, purpose, objectives, findings.
(1)   Authority: This section is adopted pursuant to N.C.G.S. part 6, article 21 of chapter 143; part 23 of article 9 of chapter 160D; and article 8 of chapter 160A.
(2)   Purpose: It is the purpose of this section to promote public health, safety, and general welfare and to minimize public and private losses due to flood conditions within floodprone areas by provisions designed to:
a.   Restrict or prohibit uses that are dangerous to health, safety, and property due to water or erosion hazards or that result in damaging increases in erosion, flood heights, or velocities;
b.   Require that uses vulnerable to floods, including facilities that serve such uses, be protected against flood damage at the time of initial construction;
c.   Control the alteration of natural floodplains, stream channels, and natural protective barriers, which are involved in the accommodation and restrain of floodwaters;
d.   Control filling, grading, dredging, and all other development that may increase erosion or flood damage; and
e.   Prevent or regulate the construction of flood barriers that will unnaturally divert flood waters or which may increase flood hazards to other lands.
(3)   Objectives: The objectives of this section are to:
a.   Protect human life, safety, and health; minimize damage to public facilities and utilities (i.e. water and gas mains, electric, telephone, cable and sewer lines, streets, and bridges) that are located in floodprone areas;
b.   Minimize expenditure of public money for costly flood control projects; minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the expense of the general public;
c.   Minimize prolonged business losses and interruptions; ensure that potential buyers are aware that property is in a special flood hazard area;
d.   Help maintain a stable tax base by providing for the sound use and development of floodprone areas in such a manner as to minimize future flood damage.
(4)   Findings:
a.   The floodprone areas within the jurisdiction of the City of Asheville (city) 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 floodprone areas of uses vulnerable to floods or hazardous to other lands which are inadequately elevated, flood-proofed, or otherwise protected from flood damage.
(b)   General provisions.
(1)   Applicability: This section shall apply to all special flood hazard areas within the city's territorial and extra-territorial jurisdiction.
(2)   Effect upon outstanding floodplain development 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 section; provided, however, that when construction is not begun under such outstanding permit within a period of six months subsequent to the date of issuance of the outstanding permit, construction or use shall be in conformity with the provisions of this section.
(3)   Special flood hazard areas: The special flood hazard areas are those identified under the Cooperating Technical State (CTS) Agreement between the State of North Carolina, FEMA, its Flood Insurance Study (FIS) and its accompanying Flood Insurance Rate Maps (FIRM), for Buncombe County dated January 6, 2010, all of which are adopted by reference and declared to be a part of this section. For purpose of grandfathering, the initial FIRMs for the Buncombe County unincorporated area are dated August 1, 1980 and for the City of Asheville are dated July 16, 1980.
(4)   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 section and other applicable regulations.
(5)   Abrogation and greater restrictions: This section is not intended to repeal, abrogate, or impair any existing easements, covenants, or deed restrictions; however, where this section and another conflict or overlap, whichever imposes the more stringent restrictions shall prevail.
(6)   Interpretation: In the interpretation and application of this section, all provisions shall be: (a) considered as minimum requirements; (b) liberally construed in favor of the city; and (c) deemed neither to limit nor repeal any other powers granted under state statutes.
(7)   Warning and disclaimers of liability: The degree of flood protection required by this section is considered reasonable for regulatory purposes and is based on scientific and engineering consideration. Larger floods can and will occur. Actual flood heights may be increased by manmade or natural causes. This section 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 section shall not create liability on the part of the city or any officer or employee thereof for any flood damages that result from reliance on this section or any administrative decision lawfully made hereunder.
(c)   Administration.
(1)   Floodplain administrator: The public works director is hereby designated to administer and implement the provisions of this section. Except as specifically stated, any act authorized by this section to be carried out by the floodplain administrator may be carried out by his/her designee.
(2)   Duties and responsibilities of the floodplain administrator: In addition to all other customary and incidental powers of the floodplain administrator as well as the powers and duties that may be conferred by other ordinances of the city and other applicable laws, statutes, rules and regulations, the floodplain administrator shall perform, but not be limited to, the following duties:
a.   Review all floodplain development applications and issue permits for all proposed development within special flood hazard areas to assure that the requirements of this section have been satisfied.
b.   Review all proposed development within special flood hazard areas to assure that all necessary local, state, and federal permits have been received.
c.   Notify adjacent communities and the North Carolina Department of Crime Control and Public Safety, Division of Emergency Management, State Coordinator for the National Flood Insurance Program prior to any alteration or relocation of a watercourse, and submit evidence of such notification to the Federal Emergency Management Agency (FEMA).
d.   Assure that maintenance is provided within the altered or relocated portion of the watercourse as referenced in the preceding paragraph, so that the flood-carrying capacity is maintained.
e.   Prevent encroachments into floodways and non-encroachment areas unless the certification and flood hazard reduction provisions of subsection 7-12-1(e)(5) are met.
f.   Obtain actual elevation (in relation to mean sea level) of the reference level (including basement) and all attendant utilities of all new and substantially improved structures, in accordance with subsection 7-12-1(d)(3); and obtain actual elevation (in relation to mean sea level) of all public utilities in accordance with the provisions of subsection 7-12-1(d)(3).
g.   Obtain actual elevation (in relation to mean sea level) to which all new and substantially improved structures and utilities have been flood-proofed, in accordance with the provisions of subsection 7-12-1(d)(3).

d.   No new habitable structures or substantial improvements to habitable structures shall be permitted in floodways and non-encroachment areas, except this subsection shall not be applicable to structures that have substantial damage.
(6)   Standards for areas of shallow flooding (zone AO as referenced on the FIRM): Located within the special flood hazard areas established in subsection 7-12-1 (b)(3), 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. In addition to subsection 7-12-1 (e)(1) and (2), all new construction and substantial improvements shall meet the following requirements:
a.   The reference level shall be elevated at least as high as the depth number specified on the flood insurance rate map (FIRM), in feet, plus a freeboard of two feet, above the highest adjacent grade; or at least two feet above the highest adjacent grade if no depth number is specified.
b.   Non-residential structures may, in lieu of elevation, be flood-proofed to the same level as required in subsection 7-12-1(e)(6)a. so that the structure, together with attendant utility and sanitary facilities, below that level shall be 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 in accordance with subsection 7-12-1(d)(3) and subsection 7-12-1(e)(2)b.
c.   Adequate drainage paths shall be provided around structures on slopes, to guide floodwaters around and away from proposed structures.
(7)   Nonconforming uses: A structure(s) or the use(s) of a structure or premises which are lawful before the effective date of this section, or before any amendment to this section after that date, but which is not in conformity with the provisions herein may be continued as a nonconforming use, or for the purposes of this section may be changed to another nonconforming use (changes in use shall be made in conformance with subsection 7-12-1 (e)). Changes in ownership of any property under the jurisdiction of this section shall not affect the continued operation of the nonconforming use. All nonconforming uses shall be subject to the following conditions:
a.   Any substantial improvement of a nonconforming structure shall be made in compliance with the provisions of this section.
b.   If the nonconforming use is discontinued for a period of 180 or more consecutive days, and there are no substantial good faith efforts to re-establish the use during this period, any future use of the building and/or premises shall conform to this section. Obtaining permits to maintain the existing use or significant continuous efforts to market the property for sale or lease for the existing use (e.g., MLS listing, realtor contract, etc.), shall be regarded as substantial good faith efforts. A nonconforming use shall be deemed discontinued after a period of more than two years regardless of any substantial good faith efforts to re-establish the use and any future use of the building and/or premises shall conform to section.
c.   If any nonconforming use or structure or substantial improvement is destroyed by any means, including floods, said use or structure may be replaced provided the replacement of said structure and/or substantial improvements thereto will not result in an increase in the level of the current regulatory flood level. In all instances, a registered professional engineer or architect shall provide the floodplain administrator with an acceptable certification demonstrating that said replacement would not result in an increase in the current regulatory flood levels.
d.   Any use which has been permitted as a restricted use and is in full compliance with this section and attached standards shall be considered a conforming use.
e.   Any change of a nonconforming use as specified herein shall be approved by the board of adjustment under the provisions of this section. Proposed changes in a nonconforming use to a residential use shall be expressly prohibited.

Sec. 7-12-2. Stormwater, soil erosion and sedimentation control, illicit discharge and connection ordinance.
(a)   Authority, purpose, objective, findings, jurisdiction, applicability, exemptions.
(1)   Authority: This section is adopted pursuant to N.C.G.S. § 143-214.7 and applicable rules promulgated by the North Carolina Environmental Management Commission (NCEMC) thereunder; Session Law 2006- 246; chapter 160A (Cities and Towns), article 14; chapter 160D (Local Planning and Development Regulation) article 9; section 5 of the North Carolina Constitution; chapter 113A, article 4 (Sedimentation Pollution Control); article 21, part 6 (Floodway Regulations).
(2)   Purpose: It is the purpose of this section to comply with the federal and corresponding state stormwater discharge National Pollution Discharge Elimination System (NPDES) regulations; to protect, maintain and enhance the environment of the City of Asheville (City), by establishing minimum requirements and procedures to control the potential adverse effects of increased stormwater runoff associated with both future development and existing developed land and non-point and point source pollution associated with new development and redevelopment as well as illicit discharges into municipal stormwater systems; to regulate the clearing, grading, excavation, filling and manipulation of the earth and the moving and storing of waters in order to control and prevent accelerated soil erosion and sedimentation; and to establish decision-making processes for development that protect the integrity of watersheds and preserve the health of water resources.
(3)   Objectives: To assure the city of the authority to take any action required by it to obtain and comply with its NPDES permit for stormwater discharges. Among other things, these regulations require the city to establish legal authority which authorizes or enables the city at a minimum to:
a.   Control the contribution of pollutants to the city's MS4 and receiving waters by stormwater discharges associated with residential, commercial, industrial, and related facility activity and the quality of stormwater discharged from sites of residential, commercial, industrial, and related facility activity; and
b.   Prohibit illicit discharges and illicit connections to the city's MS4 and receiving waters; and control the discharge to the city's MS4 and receiving waters, of spills, dumping or disposal of materials other than stormwater; and
c.   Control through intergovernmental agreements, contribution of pollutants from one municipal stormwater system to another; and
d.   Control accelerated erosion and sedimentation; and
e.   Require compliance with conditions in ordinances, permits, contracts or orders as follows:
1.   To establish and implement all inspection, surveillance and monitoring procedures necessary to determine compliance and noncompliance with permit conditions including the prohibition of illicit discharges and illicit connections to the city's MS4 and receiving waters;
2.   To require that new development and redevelopment maintain the pre-development hydrologic response in their post-development state as nearly as practicable for the applicable design storm in order to reduce flooding, stream bank erosion, non-point source pollution and increases in stream temperature, and to maintain the integrity of stream channels and aquatic habitats for biological/ecological function and drainage;
3.   To encourage the use of better management and site design practices, such as the use of vegetated conveyances for stormwater and the preservation of green space and other conservation areas to the maximum extent practicable (MEP);
4.   To establish provisions for the short-term and long-term responsibility for and maintenance of structural and non-structural stormwater BMPs to ensure that they continue to function as designed, are maintained appropriately, and pose no threat to public safety; and to minimize public and private property damage resulting from erosion, sedimentation and flooding; and to regulate developments that create demand for public investment in flood control works.
(4)   Findings:
a.   Stormwater runoff can have a significant adverse impact on the health, safety and general welfare of the city and on the quality of life of its citizens. These impacts can be in the form of pollution to our water bodies, erosion and sedimentation, flooding and other degrading impacts.
b.   The sedimentation of streams, lakes, wetlands and other waters of this State constitute a major pollution problem. Sedimentation occurs from the erosion or depositing of soil and other materials into the waters. Control of erosion and sedimentation is deemed vital to the public interest and necessary to public health and welfare, and expenditures of funds for erosion and sedimentation control programs shall be deemed for a public purpose.
c.   Changes in land use can create adverse impacts. The city has been designated a Phase II Municipal Separate Storm Sewer System (MS4) Community under the NPDES and is required to obtain a permit pursuant to the 1972 Federal Water Pollution Control Act as amended in 1987 as well as the applicable and statutory laws promulgated thereunder. In response to these requirements this jurisdiction is compelled to adopt minimum stormwater controls such as those included in this section.
d.   The city is in a unique geographic area with steep slopes, erodible soils, extreme rainfall patterns and other unique factors that require special attention and specifically different requirements from other jurisdictions.
(5)   Jurisdiction: With the exception of applying subsection 7-12-2(k), pertaining to the prohibition, detection and elimination of illicit connections, illicit discharges and improper disposal to the stormwater system in the city's extraterritorial jurisdiction, this section shall apply to the territorial and extraterritorial jurisdictions of the city as well as to all properties owned by the city within Buncombe County to include the areas designated on the map entitled "Phase II Stormwater Map of the City of Asheville, North Carolina" ("the Stormwater Map"), which is adopted simultaneously herewith along with all explanatory matters contained thereon and made a part of this section.
(6)   Applicability: Unless exempted pursuant to subsection 7-12-2(a)(7) below, beginning with and subsequent to its effective date, this section shall be applicable as follows:
a.   All development and redevelopment, including, but not limited to, site plan applications, subdivision applications, and land disturbing applications.
b.   The provisions of subsection 7-12-2(k), pertaining to prohibition, detection and elimination of illicit connections, illicit discharges and improper disposal to the stormwater system shall apply to all properties, lands, city's MS4 and waters of the state within the territorial jurisdiction of the city as well as to all properties owned by the city within Buncombe County.

f.   Review of the design plan by other agencies: Upon approval of a permit for proposed land disturbance of one acre or greater, the stormwater administrator will forward, as required, one copy of the design plan to the Buncombe County Soil and Water Conservation District ("district") for its review. The district shall review the design plan and submit its comments and recommendations to the stormwater administrator within 20 days after the district received the design plan. Failure of the district to submit its comments and recommendations to the stormwater administrator within the prescribed time shall not delay final action on the permit application by the stormwater administrator.
(5)   Review and approval:
a.   Preconstruction conference: When deemed necessary by the stormwater administrator due to the complexity, risk or ingenuity of a project, a preconstruction conference may be required.
b.   Timeline for review of permit applications: The stormwater administrator will review each complete permit application with formal plans within 30 days and for sketch plans within 15 days of receipt thereof and notify the person submitting the permit application that it has been approved, approved with conditions, approved with performance reservations, or disapproved.
c.   Approval: If the stormwater administrator finds that the permit application complies with the standards of this section, the stormwater administrator shall approve the application. The stormwater administrator may impose conditions of approval as needed to ensure compliance with this section, or other local, state or federal regulations. The conditions shall be included as part of the approval.
d.   Disapproval for content: The stormwater administrator shall disapprove a permit application if it is found that the application fails to comply with the standards of this section, and shall notify the applicant of the reason(s) for the disapproval. The applicant shall have an opportunity to submit a revised application.
e.   Other disapproval: The stormwater administrator shall disapprove a permit application if implementation of the permit application would result in a violation of the rules adopted by the NCEMC to protect riparian buffers along surface waters. In the event that a permit application is disapproved pursuant to this paragraph, the stormwater administrator shall notify the director of the Division of Land Resources (DLR) of NCDENR of such disapproval within ten days. The city shall advise the applicant and the director of the DLR in writing as to the specific reasons that the plan was disapproved. A permit application may also be disapproved upon finding that an applicant, or a parent, subsidiary, or other affiliate of the applicant is:
1.   Conducting or has conducted development, redevelopment or land disturbing activity without an approved plan, or has received notice of violation of an approved plan and grading and stormwater permit previously approved by NCEMC or a local government pursuant to the Sedimentation Pollution Control Act (Act) and has not complied with the notice within the time specified in the notice.
2.   Has failed to pay a civil penalty assessed pursuant to the Act or a local ordinance adopted pursuant to the Act by the time the payment is due.
3.   Has been convicted of a misdemeanor pursuant to NCGS 113A-64(b) or any criminal provision of a local ordinance adopted pursuant to the Act; or (For purposes of this subsection, an applicant's record may be considered for only the two years prior to the application date).
4.   Has failed to substantially comply with state rules or local ordinances and regulations adopted pursuant to the Act.
f.   Failure to timely approve: Failure to approve, approve with modifications, or disapprove a complete permit application with formal plans within 30 days of receipt shall be deemed approved. Failure to approve, approve with modifications, or disapprove a permit application with a sketch plan within 15 days of receipt shall be deemed approved.
g.   Review of revised permit application: The stormwater administrator will review each revised permit application submitted and within 15 days of receipt thereof, will notify the person submitting the permit application that it has been approved, approved with modifications, approved with performance reservations, or disapproved.
h.   Failure to recognize: Any failure of the stormwater administrator in administering this section to include but not limited to: recognizing hazardous conditions, failure to disapprove the permit application, failure to inspect, to issue a notice of violation, assess a civil penalty or file a civil action, shall not relieve the owner from responsibility for the conditions or damages resulting therefrom and shall not result in the city, its officers or employees, being responsible for the damages resulting therefrom.
i.   Failure to timely submit revised application: If a revised permit application is not resubmitted within 180 days from the date the applicant was notified of the disapproval, the permit application shall be considered withdrawn, and a new submittal for the same or substantially the same project shall be required along with the appropriate fee.
j.   Amendment to a plan: Applications for amendment of a permit application in written and/or graphic form may be made at any time under the same conditions as the original permit application. Until such time as said amendment is approved by the stormwater administrator, the land disturbing activity shall not proceed except in accordance with the permit application as originally approved. The review process for the amendment shall be the same as for a new permit application submittal.
(6)   Other considerations of the review and approval process:
a.   Display of approved plan and permit: The approved plan and grading and stormwater permit must be kept on file at the job site until the job is stabilized and completed.
b.   Revised permit application after approval: The stormwater administrator may, after approving a permit application, require a revised application upon making the following findings:
1.   Either upon review of such permit application or on inspection of the job site, determines that a significant risk of accelerated erosion, off-site sedimentation, or risk of damage due to stormwater flows exists.
2.   Upon finding that the erosion and sedimentation control or the post-construction stormwater control measures presented in the permit application are inadequate to meet the requirements of this section.
c.   Status of work: Pending the preparation of the revised permit application, work shall cease or may continue under conditions outlined by the stormwater administrator.
(d)   Permit close out and release requirements.
(1)   Permit close out: For all development, redevelopment and land disturbing activity, which requires a grading and stormwater permit pursuant to the provisions of this section, no certificate of compliance or occupancy shall be issued by the city without a final release of the grading and stormwater permit by the stormwater administrator, except where multiple units are served by a single grading and stormwater permit, in which case the city may elect to withhold a percentage of permits or certificates of occupancy until a final release of any required performance securities.
(2)   Final release requirements:
a.   As-built record drawings: For all development, redevelopment and land disturbing activity which require structural BMPs, stormwater management control facilities, conveyances and related improvements, an as-built record drawing must be submitted and approved by the stormwater administrator. The as-built record drawing shall be certified, signed and sealed by a North Carolina professional engineer or landscape architect. Requirements for the as-built record drawing and submittal can be found in the stormwater BMP manual.
b.   Certificates of completion: For all development, redevelopment and land disturbing activity which require structural BMPs, stormwater management control facilities, conveyances, and related improvements, a certificate of completion must be submitted by the professional engineer or landscape architect, the property owner, the developer and the contractor to the stormwater administrator. The certificate serves to certify that all facilities and improvements have been constructed and installed per the approved design plan, as-built record drawing and requirements set forth in the stormwater BMP manual. The certificate of completion form shall be available from the office of the stormwater administrator.
c.   Operation and maintenance agreement: For all development, redevelopment and land disturbing activity which require structural BMPs or stormwater management control facilities, an operation and maintenance agreement must be submitted and approved by the stormwater administrator, on a form available from the office of the stormwater administrator.
d.   Slope stability certifications: For all development, redevelopment and land disturbing activity which require a slope stability certificate in accordance with the provisions of this section, the slope stability certificate must be submitted and approved by the stormwater administrator. The slope stability form shall be available from the office of the stormwater administrator.
e.   Other requirements: Depending on the scope of the development, redevelopment and land disturbing activity, other items may be required for final approval. These may include, but are not limited to, easements and plats.
(3)   Final inspection: The stormwater administrator shall perform a final inspection verifying that all disturbed areas have been stabilized, that all permanent erosion control measures and stormwater management BMPs, facilities and improvements have been installed per the approved design plan, as- built record drawing and compliance with all requirements set forth in the stormwater BMP manual. A certificate of occupancy shall not be issued until there is a final inspection signed by the stormwater administrator.
(e)   Erosion prevention and sediment control.
(1)   Basic control objectives: An erosion and sedimentation control plan shall be disapproved if the plan fails to address the basic control objectives. The basic control objectives which are to be considered in developing and implementing an erosion and sedimentation control plan are:
a.   Identify critical areas: On-site areas which are subject to severe erosion and off-site areas which are especially vulnerable to damage from erosion and/or sedimentation are to be identified and receive special attention;
b.   Limit time of exposure: All land disturbing activities are to be planned and conducted to limit exposure to the shortest practicable time;
c.   Limit exposed area: All land disturbing activities are to be planned and conducted to limit the size of the area to be exposed at any one time;
d.   Control surface water: Surface water runoff originating upgrade of exposed areas shall be controlled to reduce erosion and sediment loss during the period of exposure;
e.   Control sedimentation: All land disturbing activities shall be planned and conducted so as to prevent off-site sedimentation damage; and
f.   Manage stormwater runoff: When the increase in the velocity of stormwater runoff resulting from a land disturbing activity is sufficient to cause accelerated erosion of the receiving watercourse, plans must include measures to control the velocity to the point of discharge so as to minimize accelerated erosion of the site and increased sedimentation in the stream.
(2)   Mandatory standards for land disturbing activity:
a.   Land disturbing activity subject to this section shall be undertaken in accordance with the following requirements:
1.   Land disturbing activity shall not occur within a 30-foot undisturbed buffer around all perennial and intermittent surface waters.
2.   Land disturbing activity described in subsection (a)(7)(c)(1) of this section shall observe a buffer zone around lakes and natural watercourses along the margin of the watercourse of sufficient width to confine visible siltation within the 25 percent of the buffer zone nearest the land disturbing activity.
3.   Land disturbing activity occurring pursuant to a decision rendered under subsection (j) of this section shall meet the buffer requirements established in that decision.
4.   Measurement of aquatic buffer width: The width of the undisturbed buffer is measured horizontally from the top of bank to the landward side of the watercourse (i.e. moving perpendicularly away from the water toward uplands or disturbed areas.
5.   Overgrowth of greenery: Removal of invasive species, undergrowth and selective thinning of trees smaller than four inches in diameter is allowed within the aquatic buffer provided notice is given to the office of the stormwater administrator.
6.   Stabilization of riverbanks: Most land disturbing activities in and on the bank of perennial and intermittent waters are regulated by the U.S. Army Corps of Engineers under Section 4040 of the Federal CWA and the North Carolina Division of Water Quality under Section 401 of the Federal CWA. In addition, a grading permit is required unless the activity is exempt as described in subsection 7-12-2(a)(7). In all cases, and to the maximum extent practicable, riverbank stabilization activities must use bioengineering methods and principles of natural design rather than concrete walls and other hardened structures.
7.   Trout buffers: No land disturbing activity shall be undertaken within an aquatic buffer adjacent to designated trout waters, as classified by the NCEMC that will cause adverse temperature fluctuations in the trout waters, as set forth in 15 NCAC 2B.0211 "Fresh Surface Water Classification and Standards." Exceptions and variances to buffers along designated trout streams may only be granted by DENR—Division of Land Resources.
b.   Grading activity in a designated landscape buffer zone. When developing a site in a designated landscape buffer zone, the following shall apply:
1.   Land disturbance is permitted in the designated landscape buffer zone and the developer is required to plant trees and shrubs which are 50 percent larger than normally required in order to reestablish quickly a visual buffer.
2.   Utilities are to be installed along the edge of the designated landscape buffer zone and cross perpendicular to the designated landscape buffer zone. Land disturbance that occurs in a designated landscape buffer zone shall not result in a slope that exceeds 3:1. Developers will be encouraged to provide as gradual a slope as practicable in the buffer area to provide increased soil stability and a better planting environment for buffer trees and shrubs.
3.   The land disturbing activity shall be conducted in accordance with the approved erosion and sedimentation control plan.
c.   Grading along property line: For land disturbing activities for which a formal erosion and sedimentation control plan is required by this section, no grading activity or land disturbance may be conducted within ten feet of any property line unless written notice of the grading activity or land disturbance has been provided to the adjacent property owner and approval of the stormwater administrator has been received. Grading for access point and utility extensions shall be exempt from this subsection.
d.   Grading without an approved development plan: Land disturbance without an approved development plan, defined as the grading (including mass tree removal) of a site for which no development plan has been approved, shall not be permitted.
1.   A landscape plan must be approved by the planning department and an erosion control plan must be approved by the stormwater administrator prior to initiation of the land disturbing activity. No grading and stormwater permits shall be issued prior to review and approval of the landscape plan by the planning department.
2.   The landscape plan must show the location of existing trees to be preserved and the location and type of any required buffer yard trees and street trees which will remain. The determination of the type of buffer required shall be based upon the most intense development permitted in the zoning district in which the project being graded is located.
3.   All required trees shall be planted within 30 days of completion of the land disturbance activity or within 12 months of the date the land disturbance activity was initiated, whichever is less. This time period may be extended through the posting of a financial guarantee as provided for in section 7-11-2 of the UDO.
4.   An effective permanent ground cover shall be applied on the site within 14 days of completion of the land disturbing activity unless completion occurs outside a growing season, in which case an effective temporary ground cover shall be applied within 14 days. No ground cover shall be required for bare rock.
e.   Graded slopes and fills:
1.   Angle: The angle for graded slopes and fills shall be no greater than the angle that can be retained by vegetative cover or other adequate erosion control devices or structures. In any event, slopes left exposed will, within 14 days of completion of any phase of grading, be planted or otherwise provided with temporary or permanent ground cover, devices, or structures sufficient to restrain erosion. The angle for graded slopes and fills must be demonstrated to be stable. Stable is the condition where the soil remains in its original configuration, with or without mechanical constraints. The use of gunite or similar materials is not allowed as a method for slope stabilization.
2.   Benches: Terracing or slope breaks should be used on steep slopes to reduce the length of cut and fill slopes to prevent erosion and formation of gullies. Benches should be five feet wide, rounded at the edges, and spaced according to the following table:
 
Slope
Spacing
50% (2:1)
No more than 20 vertical feet
33% (3:1)
No more than 35 vertical feet
25% (4:1)
No more than 45 vertical feet
 
3.   Compaction requirement: All fill slopes shall be compacted full depth to not less than 95 percent maximum density (Standard Proctor), shall be placed on a surface cleared of growth and debris, and be properly benched and drained.
4.   Severe slopes: All constructed severe slopes greater than 2:1 shall be designed by a North Carolina registered professional engineer. Additionally, for constructed severe slopes greater than five feet in height, an inspection and a stability certificate are required by a North Carolina registered professional engineer with geotechnical expertise sufficient to perform the inspection and stability analysis. For all constructed severe slopes within proposed or existing public rights-of-way, periodic inspections and compaction reports are required by a North Carolina registered professional engineer with geotechnical expertise.
5.   Slope setback requirements: Setback from existing adjacent property and rights-of-way lines is required for retaining walls and constructed moderate and severe slopes as indicated. For the purpose of this subsection, constructed moderate and severe slopes shall include those created for the construction of retaining walls. The setback shall be measured from and applied for both the head and the toe of the slope.
a)   The setback shall be equal to the maximum height of the slope.
b)   The required setback may be reduced if a subsurface exploration analysis of the area is completed by a North Carolina registered professional engineer with geotechnical expertise and the analysis indicates that the reduction in the setback will not cause greater risk of damage to adjacent public and private properties.
6.   Stability certificate findings: At a minimum, the stability certificate must state that the slope is free of failures, including, but not limited to cracks, sloughs and slippages, that the compaction requirement as set forth above has been met, that soil should remain in its original configuration and that temporary or permanent ground cover is provided. The stability certificate must be submitted and approved before a certificate of occupancy is issued.
f.   Fill material: Unless a permit from NCDENR—Division of Waste Management to operate a landfill is on file for the official site, acceptable fill material shall be free of organic or other degradable materials, masonry, concrete and brick in sizes exceeding 12 inches, and any materials which would cause the site to be regulated as a landfill by the State of North Carolina.
g.   Access and haul roads: Temporary access and haul roads, other than public roads, constructed or used in connection with any land disturbing activity shall be considered a part of such activity.
h.   Allowable disturbances:
1.   Maximum limits of disturbance at one time: Land disturbance in any area with a natural average slope in excess of 15 percent shall be limited to disturbing not more than five acres at a time. Any one disturbed area must be stabilized per the requirements of the soil erosion and sediment control standards as set forth in this section prior to beginning disturbance on any subsequent area.
a)   The stormwater administrator may grant a waiver to the five-acre limitation but only if: (i) the disturbance does not exceed 20 acres; and (ii) the erosion and sediment controls in the formal plan are designed for a 50-year storm; and (iii) a North Carolina licensed registered professional is contracted with to perform all required inspections as required by subsection 7-12-2(g)(5); and (iv) the area of disturbance is located a minimum of 50 feet from a perennial or intermittent stream or down slope properties.
b)   For the purposes of this provision, non-contiguous areas located within 1,500 feet of each other and owned and/or developed by the same person(s) shall be considered the same project.
2.   Steep slope and others: For properties where steep slope and/or ridgetop protection regulations apply, as defined in section 7-12-4 of the UDO, limits on maximum allowable disturbance shall be as indicated by those applicable regulations. The as-built record drawing must be submitted and approved by the stormwater administrator prior to final inspection approval for any phase of land disturbing activity.
3.   Security for re-vegetation: A security for re-vegetation is required for all land disturbances which exceeds five acres. The security shall be in the form of a construction bond, letter of credit, or certified check and must be provided prior to the issuance of the grading and stormwater permit. The security shall be sufficient to re-vegetate proposed disturbed areas and shall be valid for one year from the issuance of the permit and be updated throughout the process.
i.   Borrow and waste area:
1.   When the person conducting the land disturbing activity is also the person conducting the borrow or waste disposal activity, areas from which borrow is obtained and which are not regulated by the provisions of the Mining Act of 1971, and waste areas for surplus materials other than landfills regulated by NCDENR—Division of Waste Management, shall be considered as part of the land disturbing activity where the borrow material is being used or from which the waste material originated. When the person conducting the land disturbing activity is not the person obtaining the borrow and/or disposing of the waste, these areas shall be considered a separate land disturbing activity.
2.   The formal plan shall include a soil volume balance calculation and state if there will be borrowed or waste fill material used. If borrowed or waste fill material is generated, an approved grading permit must be secured for the borrow or waste material site prior to initiation of any land disturbing activity, unless the site is not excluded by the mining or landfill act.
(3)   Design and performance standards:
a.   Design storm protection: Erosion and sedimentation control measures, structures, and devices shall be planned, designed, and constructed to provide protection from the calculated maximum peak rate of runoff from the ten-year storm. Runoff rates shall be calculated using the procedures in the USDA, Soil Conservation Service's "National Engineering Field Manual for Conservation Practices", or other acceptable calculation procedures. If an area has been listed on the watershed overlay zone inventory by the stormwater administrator, erosion control measures for such sites or specific measures on a site shall be designed for, at a minimum, the 25-year storm. The watershed overlay zone inventory is available from the office of the stormwater administrator. The watershed overlay zone inventory shall be subject to a bi-annual review, the process and method for such a review shall be established by policy of the stormwater administrator.
b.   Innovative measures: Erosion and sedimentation measures applied alone or in combination to satisfy the intent of this section are acceptable if they are sufficient to prevent adverse secondary consequences. Innovative techniques and ideas will be considered and may be used following approval by the stormwater administrator if it can be demonstrated that such techniques and ideas are likely to produce successful results.
c.   Watershed overlay zone: In watershed overlay zones, the following design standards shall apply:
1.   Uncovered areas in watershed overlay zones shall be limited at any time to a maximum total area of 20 acres within the boundaries of the site. Only the portion of the land disturbing activity within a watershed overlay zone shall be governed by this section. Larger areas may be uncovered within the boundaries of the site with the written approval of the stormwater administrator.
2.   Erosion and sedimentation control measures, structures, and devices within watershed overlay zones shall be planned, designed and constructed to provide protection from the runoff of the 25-year storm which produces the maximum peak rate of runoff as calculated according to procedures in the United States Department of Agriculture Soil Conservation Service's "National Engineering Field Manual for Conservation Practices" or other calculations or procedures generally recognized in the field including those adopted by any other agency of this state or the United States or any generally recognized organization or association and approved by the stormwater administrator.
3.   Sediment basins within watershed overlay zones shall be designed and constructed such that the basin will have an overall sediment removal efficiency of at least 85 percent and a settling efficiency of at least 70 percent for the 40 micron (0.04 millimeter) size soil particle transported into the basin by the runoff of that two-year storm which produces the maximum peak rate of runoff as calculated according to procedures in the United States Department of Agriculture Soil Conservation Service's "National Engineering Field Manual for Conservation Practices" or other calculations or procedures generally recognized in the field including those adopted by any other agency of this state or the United States or any generally recognized organization or association and approved by the stormwater administrator.
4.   Newly constructed open channels in watershed overlay zones shall be designed and constructed with side slopes no steeper than two horizontal to one vertical (2:1) if a vegetative cover is used for stabilization unless soil conditions permit a steeper slope or where the slopes are stabilized by using mechanical devices, structural devices or other acceptable ditch liners. In any event, the angle for side slopes shall be sufficient to restrain accelerated erosion.
5.   Ground cover sufficient to restrain erosion must be provided for any portion of a land disturbing activity in a watershed overlay zone within 14 days following completion of construction. When construction activity has ceased in a particular site of a larger development, effective permanent ground cover must be applied within 14 days from the date of the last land disturbing activity.
6.   Any additional reasonable measures determined by the stormwater administrator to be required to bring the City of Asheville into compliance, or to maintain compliance with, provisions of the city's NPDES stormwater discharge permit, a total maximum daily load (TMDL) once approved by the State of North Carolina or the U.S. Environmental Protection Agency for one or more pollutants, a consent decree or other order issued under the provisions of the Clean Water Act (33 USC 1251 et seq.) or other federal or state law or regulation.
(4)   Stormwater outlet protection:
a.   Intent: Stream banks and channels downstream from any land disturbing activity shall be protected from increased degradation by accelerated erosion caused by increased velocity of runoff from the land disturbing activity.
b.   Performance standard: Persons engaged in land disturbing activity shall conduct such activity so that the post-construction velocity of the ten-year storm runoff in the receiving watercourse to the discharge point does not exceed the greater of:
1.   The non-erosive velocities for the downstream channel conditions as specified in the North Carolina Erosion and Sediment Control Planning and Design Manual, or
2.   The velocity of the ten-year storm runoff in the receiving watercourse prior to development.
c.   Acceptable management measures: Measures applied alone or in combination to satisfy the intent of this section are acceptable if there are no objectionable secondary consequences. The city recognizes that the management of stormwater runoff to minimize or control downstream channel and bank erosion is a developing technology. Innovative techniques and ideas will be considered and may be used when shown to have the potential to produce successful results. Some alternatives, while not exhaustive, are to:
1.   Avoid increases in surface runoff volume and velocity by including measures to promote infiltration to compensate for increased runoff from areas rendered impervious;
2.   Avoid increases in stormwater discharge velocities by using vegetated or roughened swales and waterways in place of closed drains and high velocity paved sections;
3.   Provide energy dissipaters at outlets of storm drainage facilities to reduce flow velocities to the point of discharge;
4.   Protect watercourses subject to accelerated erosion by improving cross sections and/or providing erosion-resistant lining; and
5.   Upgrade or replace the receiving device structure, or watercourse, such that it will receive and conduct the flow to a point where it is no longer subject to degradation from the increased rate of flow or increased velocity.
d.   Non-applicability: This subsection pertaining to stormwater outlet protection shall not apply where the applicant can demonstrate through engineer analysis on the sealed plans that stormwater discharge volumes and velocities will not create an erosion problem in the receiving watercourse.
(5)   Operations in lakes or natural watercourses: Land disturbing activity in connection with construction in, on, over, or under a lake or natural watercourse falls within the jurisdiction of appropriate state and federal agencies, including but not limited to NCDENR—Division of Water Quality and the Army Corps of Engineers. Developers should consult with the appropriate state and/or federal agencies to obtain the necessary permits and requirements. In all cases and to the maximum extent practicable, operations in lakes and natural watercourses shall minimize the extent and duration of disruption of the stream channel. Where relocation of a stream forms an essential part of the proposed activity, the relocation shall minimize unnecessary changes in the stream flow characteristics.
(6)   Uncovered areas:
a.   Ground cover: Whenever land disturbing activity is undertaken on a site, the person conducting the land disturbing activity shall install erosion and sedimentation control devices and practices that are sufficient to retain the sediment generated by the land disturbing activity within the boundaries of the site during construction upon and development of said site, and shall plant or otherwise provide a permanent ground cover sufficient to restrain erosion after completion of construction or development. Provisions for a ground cover sufficient to restrain erosion must be accomplished within 14 days following completion of construction or development. To the maximum extent practicable, native or indigenous plant species shall be used for permanent ground cover.
b.   Existing uncovered areas: All uncovered areas existing on the effective date of this section which resulted from land disturbing activities, and are subject to continued accelerated erosion, and are causing off-site damage from sedimentation, shall be provided with a ground cover or other protective measures, structures, or devices sufficient to restrain accelerated erosion and control off-site sedimentation.
c.   Extensive control measures: The stormwater administrator reserves the right to require preparation and approval of an erosion control plan in any instance wherein extensive control measures are required.
d.   Planned reservoir: This section shall not require ground cover on cleared land forming the future basin of a planned reservoir.
e.   Fee: No fee shall apply to work required under this subsection except when the stormwater administrator exercises the right to require an erosion control plan.
(7)   Responsibility for installation, operation, and maintenance of temporary and permanent soil erosion and sedimentation control measures:
a.   During construction: During the development of a site, the person conducting the land disturbing activity shall install and maintain all temporary and permanent soil erosion and sedimentation control measures as required by the approved plan, by any provision of this section, by any order adopted pursuant to this section, or any provision of the North Carolina Sediment Pollution Control Act.
b.   After construction: After site development, the property owner or person in possession or control of the land shall install and/or maintain all necessary permanent soil erosion and sedimentation control measures, except those installed within a road or street right-of-way or easement accepted for maintenance by a government agency.
c.   Clean up requirements: When sediment is transported onto a public road surface, the road shall be cleaned thoroughly at the end of each day. Sediment shall be removed from the roads by shoveling or sweeping and transported to a sediment control disposal area. Street washing shall be allowed only after sediment is removed in this manner.
d.   Cost of clean-up by city: If the city must clean-up off-site sedimentation or mitigate other erosion related public safety and environmental hazards, the person in violation will be charged for the cost of the cleanup in addition to the civil penalty. The cleanup cost shall include personnel wages, equipment usage, and related administrative overhead costs. If the violator does not pay for the cleanup cost, revoked permits shall not be re-issued. Additionally, the city shall proceed in accordance with the enforcement provisions of this section to collect the cost of the clean up.
e.   Restoration of land and waters: The city may require a person who engaged in a land disturbing activity and failed to retain sediment generated by the activity, as required by NCGS 113A-57(3), to restore the waters and land affected by the failure so as to minimize the detrimental effects of the resulting pollution by sedimentation. This authority is in addition to any other civil penalty or equitable relief.
f.   Additional measures: Whenever the city determines that significant erosion and sedimentation is occurring as a result of land disturbing activity, despite application and maintenance of protective practices, the person conducting the land disturbing activity will be required to and shall take additional protective action.
(f)   Post-construction stormwater control.
(1)   Standards for stormwater quantity control: All development and redevelopment to which this subsection applies shall comply with the standards herein. The design of facilities to comply with these standards shall be based on procedures contained in the stormwater BMP manual or as approved by the stormwater administrator guided by the spirit, purpose and intent of this section. The minimum "post-construction" stormwater control requirements included in the stormwater management plan shall provide management measures necessary to accomplish the following:
a.   Limit the two-year and ten-year developed peak discharge rates to pre-developed peak discharge rates using a duration of 24-hours with a SCS Type II design storm and pass the 50-year, 24-hour storm event. The stormwater administrator may require control to pre-development rates for the 25-year, 24-hour storm, if by using existing watershed master plan analysis it is found that that additional flow reduction is required to protect downstream properties, natural and built drainage facilities due to the additional peak flows from the 25-year 24-hour storm event.
b.   Provide extended detention for the difference between the pre-development and post development volume of the 2-year 24-hour SCS Type II design storm. The increase in runoff volume must be detained between 24-hours to 72-hours. Provided that the stormwater administrator may require volume control for the difference between the pre-development and post development volume of the 25-year 24-hour storm if by using existing watershed master plan analysis it is found that that additional volume reduction is required to protect downstream properties, natural and built drainage facilities due to the additional runoff volumes from the 25- year 24-hour storm event.
(2)   Standards for stormwater quality control: All development and redevelopment to which this subsection applies shall comply with the standards herein. The design of facilities to accomplish these standards shall be based on procedures contained in the stormwater BMP manual or approved by the stormwater administrator. The minimum "post-construction" stormwater control requirements included in the stormwater management plan shall provide management measures necessary to accomplish the following:
a.   Control and treat the stormwater runoff leaving the site from the first one inch of rain. The volume of runoff from the first inch of rain must be detained between 48 hours to 120 hours.
b.   All structural stormwater treatment systems used to meet the requirements of the program shall be designed to have a minimum of 85 percent average annual removal for total suspended solids.
c.   General engineering design criteria for all projects shall be in accordance with 15A NCAC 2H.1008(c).
d.   If the developer utilizes stormwater sheetflow measures across aquatic buffers, filtration, [bioretention], enhanced on-site infiltration, and/or other effective measures thereby managing both the stormwater quantity and quality, the post-construction stormwater control standards described in subsection 7-12-2(f)(1) and (2) above shall be altered or waived by the stormwater administrator to the extent that the measures provide the same level of treatment, discharge, and velocity control as would be accomplished under the post-construction stormwater control standards using the methods defined in the BMP manual.
(3)   Aquatic buffers: Post construction:
a.   Aquatic buffer: A 30-foot undisturbed aquatic buffer shall be required along perennial and intermittent waterbodies. Landowners may challenge the classification of a stream (i.e. perennial, intermittent, ephemeral), using the methods for delineating waters developed by the North Carolina Division of Water Quality. Property owners are responsible for the cost of having the necessary field investigations performed by competent persons. By approval of this ordinance, the North Carolina Division of Water Quality hereby authorizes appropriately trained city staff to make a field determination of the stream classification.
b.   Reduction of excess aquatic buffer: Property owners may petition the stormwater administrator for reduction of the portion of any undisturbed aquatic buffer that exceeds state minimum requirements if the property owner agrees to establish and maintain:
1.   Vegetation within the aquatic buffer to meet standards set forth in the best management practices manual or approved by the stormwater administrator as being in accord with such manual; and
2.   A level-spreader outside of the aquatic buffer ensuring sheet flow entering the buffer or undertakes other mitigating stormwater management measures approved by the stormwater administrator as acceptable under industry standards.
c.   Buffer width: The width of the undisturbed aquatic buffer is measured horizontally from the top of bank to the landward side of the watercourse. (i.e. moving perpendicularly away from the water toward uplands or disturbed areas).
d.   Substantial improvements: For substantial improvements on parcels that have previously been developed, the aquatic buffer must be restored by removing built-upon areas from the aquatic buffer and by planting and landscaping the aquatic buffer per landscape requirements as set forth in the UDO where practicable. If complete restoration of the aquatic buffer is not practicable, other mitigating stormwater management measures that enhance the function of the available buffer or otherwise substantially replace the function of the aquatic buffer may be used for compliance with this section, as approved by the stormwater administrator.
(4)   Additional standards for special situations:
a.   Trout waters: In addition to the standards for stormwater handling set out in the stormwater BMP manual, development and redevelopment that drains in whole or in part to trout waters shall design and implement the best stormwater practices that do not result in a sustained increase in the receiving water temperature and allow on-site stormwater treatment devices such as infiltration areas, bio-retention areas, and level spreaders as added controls, while meeting the other requirements of this section.
b.   Watershed overlay zones: In addition to the standards for stormwater handling set out in the stormwater BMP manual, development and redevelopment that is in whole or in part within a watershed overlay zone shall implement additional measures determined by the stormwater administrator to be required to bring the City of Asheville into compliance or to maintain compliance with provisions of the city's NPDES stormwater discharge permit, a total maximum daily load (TMDL) once approved by the State of North Carolina or the U.S. Environmental Protection Agency for one or more pollutants, a consent decree or other order issued under the provisions of the Clean Water Act (33 USC 1251 et seq.) or other federal or state law or regulation.
(5)   On-site waste water:
a.   Operation and maintenance requirements: New and replaced onsite systems for domestic wastewater installed after the effective date of this ordinance must be approved and permitted by the Buncombe County Health Department. Both the Buncombe County septic permit and documentation showing the operation and maintenance for the system are required before a permit may be issued.
b.   Standards for operation and maintenance: Onsite systems for domestic wastewater covered by this section shall be operated and maintained so as to avoid adverse effects on surface water and groundwater, including eutrophication of surface water and microbial or nitrate contamination of groundwater. Septic tank residuals shall be pumped whenever necessary to assure the proper operation of the system to meet these standards, and the seepage shall be reused or disposed of in a manner that does not present significant risks to human health, surface water or groundwater.
(6)   Standards for stormwater control measures:
a.   Stormwater BMP manual: To assist in the design and evaluation of stormwater management facilities in the city, the stormwater administrator shall prepare and adopt a stormwater BMP manual. The stormwater BMP manual shall contain recommended design procedures and criteria presented for conducting evaluations of practices. The intention of the stormwater BMP manual is to establish uniform design practices; it neither replaces the need for engineering judgment nor precludes the use of information not presented. Other accepted engineering procedures may be used to evaluate practices if approved by the stormwater administrator.
1.   If the specifications or guidelines of the stormwater BMP manual are more restrictive or apply a higher standard than other laws or regulations, that fact shall not prevent application of the specifications or guidelines in the stormwater BMP manual.
2.   If the standards, specifications, guidelines, policies, criteria, or other information in the stormwater BMP manual are amended subsequent to the submittal of an application for approval pursuant to this section but prior to approval, the old information shall control and shall be utilized in reviewing the application and in implementing this section with regard to the application.
3.   The stormwater BMP manual may be updated and expanded from time to time, based on advancements in technology and engineering, improved knowledge of local conditions, or local monitoring or maintenance experience.
b.   Evaluation according to contents of the stormwater BMP manual: All stormwater control measures and stormwater treatment practices (also referred to as best management practices, or BMPs) required under this section shall be evaluated by the stormwater administrator according to the policies, criteria, and information, including technical specifications and standards and the specific design criteria for each stormwater practice, in the stormwater BMP manual. The stormwater administrator shall determine whether they will be adequate to meet the requirements of this section.
c.   Determination of adequacy; presumptions and alternatives: Stormwater treatment practices that are designed, constructed, and maintained in accordance with the criteria and specifications in the stormwater BMP manual will be presumed to meet the minimum water quality and quantity performance standards of this section. Whenever an applicant proposes to utilize a practice or practices not designed and constructed in accordance with the criteria and specifications in the stormwater BMP manual, the applicant shall have the burden of demonstrating that the practice(s) will satisfy the minimum water quality and quantity performance standards of this section. The stormwater administrator may require the applicant to provide such documentation, calculations, and examples as necessary to determine whether such an affirmative showing is made.
(7)   Locations and dedication of BMPs, facilities and improvements:
a.   Upon review and recommendation of the stormwater administrator and the director of public works, city council may approve BMPs being located within the city's public rights-of-way. In determining whether to allow a BMP within a city public right-of-way, the factors to consider shall consist of, but not be limited to, whether the BMP is a public benefit, the annual cost to the city to maintain the BMP, the potential liability the BMP exposes to the city, and any other related factors.
b.   The city may accept dedication, subject to final approval from city council, of any existing or future BMPs and stormwater management facilities for maintenance, provided such facility meets all the requirements of this section and any other policies of the city and includes adequate and perpetual access and sufficient area, by easement or otherwise, for inspection and regular maintenance. The city may require as a condition of public acceptance, that the owner arrange for funding costs associated with future maintenance of the BMP or stormwater management facility. Nothing herein shall require the city to accept maintenance of any BMP or stormwater management facility.
(8)   Operation and maintenance of structural BMPs:
a.   Operation and maintenance agreement: The applicant or owner of a site that is required to have a structural BMP pursuant to this section must execute an operation and maintenance agreement prior to issuance of a certificate of occupancy for development or redevelopment. The form "Operation and Maintenance Agreement," shall be provided by the office of the stormwater administrator.
b.   Content of operation and maintenance agreement: The operation and maintenance agreement shall require the property owner(s) to maintain, repair, and, if necessary, reconstruct the structural BMP, and shall state the terms, conditions, and schedule of maintenance for the structural BMP, and the right of the city to abate a violation. Additionally, it shall grant the city a right of entry in the event the stormwater administrator has reason to believe it has become necessary to inspect, monitor, maintain, repair, or reconstruct the structural BMP. In no case, however, shall the right of entry confer an obligation on the city to assume responsibility for the structural BMP. Additionally, the agreement shall include language to bind the parties thereto and all subsequent owners, successors and assigns, of the site, portions of the site, and lots or parcels served by the structural BMP.
c.   Maintenance responsibility: The final responsibility for complying with the operation and maintenance agreement provided herein remains with the property owner.
d.   Failure to maintain: If the owner fails to maintain the structural BMP in accordance with the operation and maintenance agreement, the city shall proceed in accordance with subsection 7-12-2(i). Any costs incurred by the city to abate such failure shall be recovered by the city at 120 percent of the actual cost.
e.   Recordation: The operation and maintenance agreement shall be referenced on the final plat; and if there is no final plat, then the agreement shall be referenced on an as-built record drawing and also recorded in the Buncombe County Register of Deeds Office, so as to appear in the chain of title of all subsequent purchasers under generally accepted searching principles, at the expense of the owner/applicant prior to the issuance of the certificate of occupancy.
f.   Deed restrictions and protective covenants: Upon conveyance of real property that is subject to or should be subject to a recorded operation and maintenance agreement, the property owner shall include in the deed of conveyance, deed restrictions, and protective covenants, imposing upon the new owner the responsibility for maintenance of the structural BMPs. Failure to know of the existence of structural BMPs on property prior to purchase is not an excuse from the obligation to maintain the structural BMPs. A failure to include deed restrictions and protective covenants as required by this subsection constitutes negligence per se.
(g)   Inspections and investigations.
(1)   City inspections:
a.   Inspections: The city shall perform routine, random, complaint based, systematic inspections or a combination hereof to ensure continued compliance with the requirements of this section. The city may also conduct joint inspections with other agencies inspecting under environmental or safety laws during or post construction.

(j)   Variances, exceptions and appeals.
(1)   Variances: Any aggrieved person may petition for a variance to the board of adjustment to use one's land in a manner otherwise prohibited by this section. Variances may also be requested from the aquatic buffer requirements, deed restrictions and protective covenants required herein. Reasonable and appropriate conditions and safeguards may be imposed on any variance granted. Merely providing that the variance would permit a greater profit from the property shall not be considered adequate justification for a variance. All of the procedural requirements of the entity charged with granting a variance shall be met by the applicant. Provided however, only the NCDENR—Division of Land Resources may grant a variance or exception as herein below set forth, to aquatic buffers along designated trout streams. The stormwater administrator may support an applicant's appeal for a variance if the applicant's application satisfies all of the following criteria:
a.   Unnecessary hardships would result from strict application of this section.
b.   The hardships result from conditions that are peculiar to the property, such as the location, size, or topography of the property.
c.   The hardships did not result from actions taken by the applicant.
d.   The requested variance is consistent with the spirit, purpose, and intent of this section; will protect water quality; will secure public safety and welfare; and will preserve substantial justice.
(2)   Exceptions: The stormwater administrator may approve plans that do not comply with the mandatory standards of subsection 7-12-2(e)(2) of this section if the land disturbing activity is for the construction of facilities to be located on, over, or under a lake or natural water course or work done for the purposes of creating trails, walkways, river access areas, and similar facilities along the rivers, creeks or streams. Where one or more measures required under subsection 7-12-2(e)(2) are not practicable, the stormwater administrator may approve plans provided that additional measures are installed that provide the same level of treatment, discharge and velocity control.
a.   Required exceptions: Notwithstanding the variance allowance herein, the stormwater administrator shall grant an exception from the aquatic buffer requirements, deed restrictions and protective covenants in any of the following instances:
1.   When there is a lack of practical alternatives for a road crossing, railroad crossing, bridge, airport facility, or utility crossing as long as it is located, designed, constructed, and maintained to minimize disturbance, provide pollutant removal, protect against erosion and sedimentation, have the least adverse effects on aquatic life and habitat, and protect water quality to the maximum extent practicable through the use of the BMPs.
2.   When there is a lack of practical alternatives for a stormwater management facility; a stormwater management pond; or a utility, including, but not limited to, water, sewer, or gas construction and maintenance corridor, as long as it is located 15 feet landward of all perennial and intermittent surface waters and as long as it is located designed, constructed, and maintained to minimize disturbance, provide pollutant removal, protect against erosion and sedimentation, have the least adverse effects on aquatic life and habitat, and protect water quality to the maximum extent practicable through the use of BMPs.
3.   A lack of practical alternatives may be shown by demonstrating that, considering the potential for a reduction in size, configuration, or density of the proposed activity and all alternative designs, the basic project purpose cannot be practically accomplished in a manner which would avoid or result in less adverse impact to surface waters.
b.   Limitation of aquatic buffer with a granted exception: Where a temporary and minimal disturbance has been permitted as an exception to the aquatic buffer, to the extent practicable, land disturbing activities in the aquatic buffer shall be limited to a maximum of ten percent of the total length of the aquatic buffer within the site to be disturbed such that there is not more than 100 linear feet of disturbance in each 1,000 linear feet of aquatic buffer.
(3)   Appeals: Any aggrieved party may file an appeal for or from the issuance of a variance, or from the denial/grant of an exception, penalty assessment, notice of violation, permit disapproval/modification, order, requirement, determination or interpretation rendered under the provisions of this section.

Sec. 7-12-3. Protected mountain ridges.
(a)   Purpose. The purpose of this provision is to expand the coverage of the Mountain Ridge Protection Act of 1983 (as amended) in the City of Asheville and the extraterritorial planning jurisdiction of the City of Asheville to further regulate the construction of tall buildings or structures on mountain ridges. This expanded regulation will insure that supplying water to, and disposing of sewage from, buildings at high elevations does not infringe on the groundwater rights and endanger the health of those persons living at lower elevations; that adequate fire protection will be available; that such buildings or structures will not be a hazard to air navigation; and that such tall buildings will not detract from the natural beauty of the mountains.
(b)   Authority. This provision is adopted pursuant to the authority conferred by N.C. Gen. Stat. sec. 113A-208(a), as amended.
(c)   Jurisdiction. This provision shall apply to the construction of tall buildings or structures as defined in N.C. Gen. Stat. sec. 113A-206(3), on protected mountain ridges as defined hereinafter within the corporate limits of the City of Asheville, North Carolina, and within the extraterritorial planning jurisdiction of the City of Asheville in accordance with N.C. Gen. Stat. sec. 113A-208, as amended.
(d)   Tall buildings or structures. "Tall buildings or structures" include any building, structure, or unit within a multi-unit building with a vertical height of more than 40 feet measured from the top of the foundation of said building, structure, or unit and the uppermost point of said building, structure, or unit; provided, however, that where such foundation measured from the natural finished grade of the crest or the natural finished grade of the high side of the slope of a ridge exceeds three feet, then such measurement in excess of three feet shall be included in the 40-foot limitation described herein; provided, further, that no such building, structure, or unit shall protrude at its uppermost point above the crest of the ridge by more than 35 feet. For the purposes of this section 7-12-3, "tall buildings or structures" do not include:
· Water, radio, telephone or television towers or any equipment for the transmission of electricity or communications or both;
· Structures of a relatively slender nature and minor vertical projections of a parent building, including chimneys, flagpoles, flues, spires, steeples, belfries, cupolas, antennas, poles, wires, or windmills; or
· Buildings and structures designated as National Historic Sites on the National Archives Registry.
(e)   Protected mountain ridges defined. The City of Asheville, North Carolina, in accordance with N.C. Gen. Stat. sec. 113A-206(6) as amended, hereby eliminates the 3,000-elevation requirement in defining a protected mountain ridge for the purpose of applying the Mountain Ridge Protection Act in the City of Asheville and its extraterritorial planning jurisdiction. "Protected mountain ridges" are defined, therefore, in the City of Asheville and its extraterritorial planning jurisdiction, as all mountain ridges whose elevation is 500 or more feet above the elevation of an adjacent valley floor.
(f)   Protected Mountain Ridge Act compliance. The provisions of N.C. Gen. Stat. sec. 113A-209 shall be applicable to protected mountain ridges as defined hereinbefore.
(g)   Filing of maps. In accordance with N.C. Gen. Stat. sec. 113A-212, a map or maps tentatively identifying the protected mountain crests as defined by this section has been filed by the North Carolina Secretary of Natural Resources and Community Development with the Buncombe County Board of Commissioners and the Asheville City Council. A map or maps identifying the protected mountain ridges (and) crests in the City of Asheville, North Carolina, has been filed with the Buncombe County Register of Deeds.
