AUTHORITY AND ENACTMENT The North Carolina General Assembly has, in Chapter 153A, Article 6, Section 121, General Ordinance Making Power; and in Chapter 143, Article 21, Water and Air Resources, authorized Randolph County to adopt regulations designed to promote public health, safety, and general welfare of its citizenry. In addition, NCGS § 160D-926 specifically authorized Randolph County to enact and enforce water supply watershed management regulations. The Randolph County Board of Commissioners does hereby ordain and enact into law the following articles as the Randolph County Watershed Protection Ordinance. B. JURISDICTION The provisions of this Randolph County Watershed Protection Ordinance shall apply within the areas designated as a Water Supply Watershed by the North Carolina Environmental Management Commission and shall be defined and established on a water supply watershed protection map of Randolph County, North Carolina, which is adopted simultaneously herewith. The watershed map and all explanatory matter contained thereon accompany and are hereby made part of this Randolph County Watershed Protection Ordinance. This Ordinance shall be permanently kept on file in the office of the Clerk to the Randolph County Board of Commissioners. C. EXCEPTIONS TO APPLICABILITY Nothing contained herein shall repeal, modify, or amend any Federal or State law or regulation, or any ordinance or regulation pertaining thereto except any ordinance which these regulations specifically replace; nor shall any provision of this Ordinance amend, modify, or restrict any provisions of the Code of Ordinances of Randolph County; however, the adoption of this Ordinance shall and does amend all ordinances, resolutions, and regulations in effect in Randolph County at the time of the adoption of this Ordinance that may be construed to impair or reduce the effectiveness of this Ordinance or to conflict with any of its provisions. It is not intended that these regulations interfere with any easement, covenants, or other agreements between parties. However, if the provisions of these regulations impose greater restrictions or higher standards for the use of a building or land, then the provisions of these regulations shall control. Existing development, as defined in this Ordinance, is not subject to the RANDOLPH COUNTY UNIFIED DEVELOPMENT ORDINANCE PAGE 313 F. ARTICLE 800: WATERSHED PROTECTION ORDINANCE 1779 requirements of this Ordinance. Expansions to existing development must meet the requirements of this Ordinance, except single-family residential development unless the expansion is a part of the common plan of development. In an expansion, the built-upon area of the existing development is not required to be included in the density calculations. Where there is a net increase of built- upon area, only the area of net increase is subject to this Ordinance. Where existing development is being replaced with a new built-upon area, and there is a net increase of built-upon area, only areas of the net increase shall be subject to this Ordinance. If a nonconforming lot of record is not contiguous to any other lot owned by the same party, then that lot of record shall not be subject to the development restrictions of this Ordinance if it is developed for single-family residential purposes. Randolph County requires the combination of contiguous nonconforming lots of records owned by the same party to establish a lot or lots that meet requirements in Section 802 of this Ordinance. Any lot or parcel created as part of a family subdivision after the effective date of these rules shall be exempt from these rules if it is developed for one single-family detached residence and if it is exempt from local subdivision regulation. Any lot or parcel created as part of any other type of subdivision, that is exempt from the Randolph County Subdivision Ordinance shall be subject to the land use requirements (including impervious surface requirements) of these rules, except that such a lot or parcel must meet the minimum buffer requirements to the maximum extent practicable. An applicant may exceed the density limits in Article 803 if all of the following circumstances apply: (1) The property was developed before the effective date of the Randolph County Watershed Protection Ordinance; (2) The property has not been combined with additional lots after January 1, 2021; (3) The property has not been a participant in a density averaging transaction under NCGS § 143-214.5(d2); (4) The current use of the property is nonresidential; RANDOLPH COUNTY UNIFIED DEVELOPMENT ORDINANCE PAGE 314 GONNiY,0,4 "r' ARTICLE 800: WATERSHED PROTECTION ORDINANCE d a: 1779 (5) In the sole discretion, and at the voluntary election, of the property owner, the stormwater from all of the existing and new built-upon area of the property is treated under all applicable Randolph County, State, and Federal laws and regulations; and (6) The remaining vegetated buffer on the property is preserved per the requirements of this Ordinance. D. REPEAL OF EXISTING WATERSHED ORDINANCE This Ordinance in part carries forward by re-enactment, some of the Randolph County Watershed Protection Ordinance adopted by the Randolph County Board of Commissioners on October 7, 1997, and as amended, and it is not the intention to repeal but rather to re-enact and continue in force such existing provisions so that all rights and liabilities that have accrued thereunder are preserved and may be enforced. All provisions of the Randolph County Watershed Ordinance which are not re-enacted herein are hereby repealed. All suits at law or in equity and/or all prosecutions resulting from the violation of any ordinance provisions heretofore in effect, which are now pending in any court of this state or of the United States, shall not be abated or abandoned by reason because of the adoption of this Ordinance, but shall be prosecuted to their finality the same as if this Ordinance had not been adopted; and all violations of the existing Randolph County Watershed Protection Ordinance, prosecutions for which have not yet been instituted, may be hereafter filed and prosecuted; and nothing in this Ordinance shall be so construed as to abandon, abate or dismiss any litigation or prosecution now pending and/or which may heretofore have been instituted or prosecuted. E. CRIMINAL PENALTIES Any person violating any provisions of this Ordinance shall be guilty of a violation of this Ordinance and be subject to Article 400, Section 405. The maximum fine for each offense shall not exceed $500.00. Each day that the violation continues shall constitute a separate offense. F. REMEDIES If any subdivision, development, and/or land use is found to violate this Ordinance, the Randolph County Board of Commissioners may, in addition to all other remedies available either in law or in equity, institute a civil penalty of $500.00, action or proceedings to restrain, correct, or abate the violation; to prevent the occupancy of the building, structure, or land; or to prevent any illegal act, conduct, business, or use in or about the premises. Also, the North Carolina Environmental Management Commission may assess civil penalties under NCGS 143-215.6(a). Each day that the violation continues shall constitute a separate offense. RANDOLPH COUNTY UNIFIED DEVELOPMENT ORDINANCE PAGE 315 GONNiY,M0,4 to a: ARTICLE 800: WATERSHED PROTECTION ORDINANCE 1779 If the Watershed Administrator finds that any of the provisions of this Ordinance are being violated, he shall notify in writing the person responsible for such violation, indicating the nature of the violation, and ordering the action necessary to correct it. He shall order the discontinuance of the illegal use of land, buildings, or structures; removal of illegal buildings or structures, or additions, alterations, or structural changes thereto; discontinuance of any illegal work being done; or shall take any action authorized by this Ordinance to ensure compliance with or to prevent violation of its provisions. If a ruling of the Watershed Administrator is questioned, the aggrieved party or parties may appeal such ruling to the Watershed Review Board. H. SEVERABILITY Should any section or provision of this Ordinance be declared invalid or unconstitutional by any court of competent jurisdiction, the declaration shall not affect the validity of this Ordinance as a whole or any part thereof that is not specifically declared to be invalid or unconstitutional. EFFECTIVE DATE This Ordinance shall take effect and be in force on the date of adoption of the Randolph County Unified Development Ordinance. 802. SUBDIVISION REGULATIONS A. GENERAL PROVISIONS No subdivision plat of land within the Water Supply Watershed shall be filed or recorded by the Randolph County Register of Deeds until it has been approved with the provisions of this Article. Likewise, the Randolph County Clerk of Superior Court shall not order or direct the recording of a plat if the recording of such plat would conflict with this Article. The approval of a plat does not constitute or affect the acceptance by Randolph County or the public of the dedication of any street or other ground, easement, right-of-way, public utility line, or other public facility shown on the plat and shall not be construed to do so. All subdivisions shall conform to the mapping requirements contained in NCGS 47-30. All subdivisions of land within the jurisdiction of Randolph County after the effective date of this Ordinance shall require a plat to be prepared, approved, and recorded under this Ordinance. B.

The plat shall be recorded within thirty days of approval. The Subdivider shall provide the Watershed Administrator with evidence the plat has been recorded with the Randolph County Register of Deeds within five working days. C. SUBDIVISION STANDARDS AND REQUIRED IMPROVEMENTS All lots shall provide adequate building space with the development standards contained in Article 803. Lots that are smaller than the minimum required for residential lots may be developed using built-upon area criteria under Article 803. To calculate the built-upon area, the total project area shall include the total acreage in the tract on which the project is to be developed. RANDOLPH COUNTY UNIFIED DEVELOPMENT ORDINANCE PAGE 318 ARTICLE 800: WATERSHED PROTECTION ORDINANCE d a: 1779 The application shall be accompanied by a description of the proposed method of providing stormwater drainage. The subdivider shall provide a drainage system that diverts stormwater runoff away from surface waters, incorporates Stormwater Control Measures to minimize water quality impacts, and meets any local requirements. The application shall, where required, be accompanied by the Sedimentation and Erosion Control Plan approved by the North Carolina Division of Land Quality administering a Sedimentation and Erosion Control Ordinance approved by the North Carolina Division of Energy, Mineral and Land Resources. Roads constructed in critical areas and watershed vegetated conveyance areas. Where possible, roads should be located outside of critical areas and watershed vegetated conveyance areas. Roads constructed within these areas shall be designed and constructed to minimize their impact on water quality. D. CONSTRUCTION PROCEDURES No construction or installation of improvements shall commence in a proposed subdivision until a subdivision plat has been approved. No building or other permits shall be issued for the erection of a structure on any lot not on record at the time of adoption of this Ordinance until all requirements of this Ordinance have been met. The subdivider, before commencing any work within the subdivision, shall plan with the Watershed Administrator to provide for adequate inspection. E. PENALTIES FOR TRANSFERRING LOTS IN UNAPPROVED SUBDIVISIONS Any person who, being the owner or agent of the owner of any land located within the jurisdiction of Randolph County, thereafter subdivides his land in violation of this Ordinance or transfers or sells land by reference to, the exhibition of, or any other use of a plat showing a subdivision of the land before the plat has been properly approved under this Ordinance and recorded in the Randolph County Register of Deeds, shall be guilty of violation of this Ordinance and be subject to Article 400, Section 405. The description by metes and bounds in the instrument of transfer or other document used in the process of selling or transferring land shall not exempt the transaction from this penalty. Randolph County may bring an action for an injunction of any illegal subdivision, transfer, conveyance, or sale of land, and the court shall, upon appropriate findings, issue an injunction and order requiring the offending party to comply with this Ordinance. F. STORM WATER DRAINAGE FACILITIES The application shall be accompanied by a description of the proposed method of providing stormwater drainage.

Project density shall be calculated as the total built-upon area divided by the total project area. 2. A project with existing development, as that term is defined in the Ordinance, may use the calculation method in Sub-item (1) of this item or may calculate project density as the difference of total built-upon area minus existing built-upon area divided by the difference of total project area minus existing built-upon area. 3. Expansions to existing development shall be subject to 15A NCAC 02B .0624 except as excluded in 15A NCAC 02B .0622 (1) (d). 4. Where there is a net increase of built-upon area, only the area of the net increase shall be subject to 15A NCAC 02B .0624. 5. Where existing development is being replaced with a new built-upon area, and there is a net increase of built-upon area, only the area of the net increase shall be subject to 15A NCAC 02B .0624. 6. The total project area shall exclude the following: a. Areas below the normal high-water line (NHWL); and b. Areas defined as coastal wetlands according to 15A NCAC 07H .0205, herein incorporated by reference, including subsequent amendments and editions, and available at no cost at http://reports.oah.state.nc.us/ncac/, as measured landward from the NWHL. 7. Projects under a common plan of development shall be considered as a single project for purposes of density calculation except that on a case-by- case basis, Randolph County may allow projects to be considered to have both high and low-density areas based on one or more of the following criteria: a. Natural drainage area boundaries; b. Variations in land use throughout the project; or c. Construction phasing. RANDOLPH COUNTY UNIFIED DEVELOPMENT ORDINANCE PAGE 324 /ii.Mo9Jy ARTICLE 800 WATERSHED PROTECTION ORDINANCE LOW-DENSITY PROJECTS: In addition to complying with the project density requirements of this Ordinance, low- density projects shall comply with the following: 1. Stormwater runoff from the project shall be released to vegetative areas as dispersed flow or transported by vegetated conveyances to the maximum extent practicable. In determining whether these criteria have been met, Randolph County shall consider site-specific factors such as topography and site layout as well as protection of water quality. Vegetated conveyances shall be maintained in perpetuity to ensure that they function as designed. Vegetated conveyances that meet the following criteria shall be deemed to satisfy the requirements of this sub-item: a. Side slopes shall be no steeper than 3:1 (horizontal to vertical) unless it is demonstrated to Randolph County that the soils and vegetation will remain stable in perpetuity based on engineering calculations and on-site soil investigation; and b. The conveyance shall be designed so that it does not erode during the peak flow from the ten-year storm event as demonstrated by engineering calculations. 2. In place of vegetated conveyances, low-density projects shall have the option to use curb and gutters with outlets to convey stormwater to grassed swales or vegetated areas. Requirements for these curb outlet systems shall be as follows: a. The curb outlets shall be located such that the swale of a vegetated area can carry the peak flow from the ten-year storm at a non-erosive velocity; b. The longitudinal slope of the swale or vegetated area shall not exceed five percent except where not practical due to physical constraints. In these cases, devices to slow the rate of runoff and encourage infiltration to reduce pollutant delivery shall be provided; c. The swale's cross-section shall be trapezoidal with a minimum bottom width of two feet; d. The side slopes of the swale or vegetated area shall be no steeper than 3:1 (horizontal to vertical); e. The minimum length of the swale or vegetated area shall be one hundred feet; and RANDOLPH COUNTY UNIFIED DEVELOPMENT ORDINANCE PAGE 325 4o�Mii .�o9Jy ARTICLE 800: WATERSHED PROTECTION ORDINANCE f. Low-density projects may use treatment swales designed under 15A NCAC 02H .1016 instead of the requirements specified in sub-items (a) through (e) above. OPTIONS FOR IMPLEMENTING PROJECT DENSITY: Randolph County has the following options in place of or in addition to the requirements of the above sections as appropriate. 1. Randolph County may allow only low-density development in the water supply watershed areas under this Ordinance. 2. Randolph County may regulate low-density single-family detached residential development using the minimum lot size requirements, dwelling unit per acre requirements, built-upon area percentages, or some combinations of these. 3. Outside of WS-I watersheds and the critical areas of WS-II, WS-III, and WS- IV watersheds, Randolph County may regulate new development under the 10/70 Option under the following requirements: a. A maximum of ten percent of the land area of a water supply watershed outside of the critical area and within Randolph County's planning jurisdiction may be developed with new development projects and expansions of an existing development of up to seventy percent built-upon area. b. In the water supply watershed classified on or before August 3, 1992, the beginning amount of acreage available under this option shall be based on Randolph County's jurisdiction as delineated on July 1 , 1993. In water supply watersheds classified after August 3, 1992, the beginning amount of acreage available under this option shall be based on Randolph County's jurisdiction as delineated on the date the water supply watershed classification became effective. The average within the critical area shall not be counted under the 10/70 Option acreage; c. Projects that are covered under the 10/70 Option shall comply with the low-density requirements outlined in the Low-Density Project above; d. The maximum built-upon area allowed on any given new development project shall be seventy percent; e. Randolph County having jurisdiction within a designated water supply watershed may transfer, in whole or in part, its RANDOLPH COUNTY UNIFIED DEVELOPMENT ORDINANCE PAGE 326 V",6,1 ate; ARTICLE 800 WATERSHED PROTECTION ORDINANCE 1779 right to the 10/70 land area to another local government within the same water supply watershed upon submittal of a joint resolution and approval by the Environmental Management Commission; and f. When the water supply watershed is composed of public lands, such as National Forest land, Randolph County may count the public land acreage within the watershed outside of the critical area in calculating the acreage allowed under this provision. 4. New development shall meet the development requirements on a project- by-project basis except Randolph County may submit ordinances that use density or built-upon area criteria averaged throughout Randolph County's watershed jurisdiction instead of on a project-by-project basis within the watershed. Before approval of the ordinance, Randolph County shall demonstrate to the Environmental Management Commission that the provisions as averaged meet or exceed the statewide minimum requirements and that a mechanism exists to ensure the planned distribution of development potential throughout Randolph County's jurisdiction within the watershed. 5. Randolph County may administer oversight of future development activities in single-family detached residential developments that exceed the applicable low-density requirements by tracking dwelling units rather than percentage built-upon area, as long as the SCM is sized to capture and treat runoff from (i) all pervious and built-upon surfaces shown on the development plan and (ii) any off-site drainage from pervious and built-upon surfaces, and when an additional safety factor of fifteen percent of the built- upon area of the project site if figured in. 807: DENSITY AVERAGING An applicant may average development density on up to two noncontiguous properties for purposes of achieving compliance with the water supply watershed development standards if all the following circumstances exist: 1. The properties are within the same water supply watershed. If one of the properties is in the critical area of the watershed, the critical area property shall not be developed beyond the applicable density requirements for its classification. 2. Overall project density meets applicable density or stormwater control requirements under 15A NCAC 2N .0200. RANDOLPH COUNTY UNIFIED DEVELOPMENT ORDINANCE PAGE 327 "^ } ARTICLE 800: WATERSHED PROTECTION ORDINANCE d a: 1779 3. Vegetated setbacks on both properties meet the minimum statewide water supply watershed protection requirements. 4. Built-upon areas are designed and located to minimize stormwater runoff impact on the receiving waters, minimize concentrated stormwater flow, maximize the use of sheet flow through vegetated areas, and maximize the flow length through vegetated areas. 5. Areas of concentrated density development are in upland areas and, to the maximum extent practicable, away from surface waters and drainage ways. 6. The property or portions of the properties that are not being developed will remain in a vegetated or natural state and will be managed by a homeowners' association as a common area, conveyed to Randolph County as a park or greenway, or placed under a permanent conservation or farmland preservation easement unless it can be demonstrated that Randolph County can ensure long-term compliance through deed restrictions and an electronic permitting mechanism. A metes and bounds description of the area to remain vegetated and limits on use shall be recorded on the subdivision plat, in homeowners' covenants, and on the individual deed and shall be irrevocable. 7. Development permitted under density averaging and meeting applicable low-density requirements shall transport stormwater runoff by vegetated conveyances to the maximum extent practicable. 8. A Special Use Permit or other such permit or certificate shall be obtained from the Randolph County Watershed Review Board or the Randolph County Zoning Board of Adjustment to ensure that both properties considered together meet the standards of this Ordinance and that potential owners have a record of how the watershed regulations were applied to the properties. 808: CLUSTER DEVELOPMENT Cluster development is allowed in all Watershed Areas, except WS-I, under the following conditions: 1. Minimum lot sizes do not apply to single-family cluster development projects; however, the total number of lots shall not exceed the number of lots allowed for single-family detached developments as outlined in Section 805. The density or built-upon area for the project shall not exceed that allowed for the critical area or protected area, whichever applies. RANDOLPH COUNTY UNIFIED DEVELOPMENT ORDINANCE PAGE 328 GONNiY,M0,4 to d a: ARTICLE 800: WATERSHED PROTECTION ORDINANCE 1779 2. All built-upon areas shall be designed and located to minimize stormwater runoff impact on the receiving waters and minimize concentrated stormwater flow, maximize the use of sheet flow through vegetated areas, and maximize the flow length through vegetated areas. 3. Areas of concentrated density development shall be located in upland areas and as far as practicable from surface waters and drainage ways. 4. The remainder of the tract shall remain in a vegetated or natural state. The title to the open space area shall be conveyed to an incorporated homeowner's association for management; or a conservation organization for preservation in a permanent easement. 5. Cluster developments that meet the applicable low-density requirements shall transport stormwater runoff by vegetated conveyances to the maximum extent practicable. 809: VEGETATED SETBACKS REQUIRED A minimum one-hundred-foot vegetative buffer (fifty feet on each side of perennial water) is required for all new development activities along all perennial waters indicated on the most recent versions of the USGS 1:24,000 (7.5 minute) scale topographic maps or as determined by Randolph County studies. Desirable artificial streambank or shoreline stabilization is permitted. Where USGS topographic maps do not distinguish between perennial and intermittent streams, an on-site stream determination may be performed by an individual qualified to perform such stream determinations. No new development is allowed in the buffer except for water-dependent structures, other structures such as flag poles, signs, and security lights which result in only diminutive increases in impervious areas, and public projects such as road crossings and greenways where no practical alternative exists. These activities should minimize built-upon surface area, direct runoff away from the surface waters, and maximize the utilization of stormwater Best Management Practices. Any such development must obtain a Special Use Permit from the Randolph County Watershed Review Board. 810: APPLICATION OF REGULATIONS No building or land shall hereafter be used, and no development shall take place except in conformity with the regulations herein specified for the watershed area in which it is located. RANDOLPH COUNTY UNIFIED DEVELOPMENT ORDINANCE PAGE 329 GD�NiY,#0,4 • ARTICLE$00:WATERSHED PROTECTION ORDINANCE 1779 No area required for complying with the provisions of this Ordinance shall be included in the area required for another building. Every residential building hereafter erected, moved, or structurally altered shall be located on a lot that conforms to the regulations herein specified, except as permitted in Section 809. If a use or class of use is not specifically indicated as being allowed in a watershed area, such use or class of use is prohibited. 811 : RULES GOVERNING THE INTERPRETATION OF WATERSHED AREA BOUNDARIES Where uncertainty exists as to the boundary of the watershed areas, as shown on the Watershed Protection Map of Randolph County, North Carolina, the following rules shall apply. A. Where boundaries are indicated as approximately following either a street, alley, railroad, or highway lines or centerlines thereof, such lines shall be construed to be said boundaries. B. Where area boundaries are indicated as approximately following lot lines, such lot lines shall be construed to be said boundaries. However, a surveyed plat prepared by a registered land surveyor may be submitted to Randolph County as evidence that one or more properties along these boundaries do not lie within the watershed area. C. Where the watershed area boundaries lie at a scaled distance more than twenty-five feet from any parallel lot line, the location of the watershed area boundaries shall be determined by use of the scale appearing on the watershed map.

RANDOLPH COUNTY UNIFIED DEVELOPMENT ORDINANCE PAGE 336 4o�Mii Mo9Jy ARTICLE 800: WATERSHED PROTECTION ORDINANCE • 777% 824: POWERS AND DUTIES OF THE WATERSHED REVIEW BOARD A. ADMINISTRATIVE REVIEW The Watershed Review Board shall hear and decide appeals from any decision or determination made by the Watershed Administrator in the enforcement of this Ordinance. B. VARIANCES The Watershed Review Board shall have the power to authorize, in specific cases, minor variances from the terms of this Ordinance, and may review major variance requests and make recommendations to the North Carolina Environmental Management Commission regarding the same. In addition, Randolph County shall notify and allow a reasonable comment period for all other local governments having jurisdiction in the designated watershed where the variance is being considered. (1) Application for a variance shall be made on the proper form obtainable from the Watershed Administrator and shall include the following information: (a) A site plan is drawn to a scale of at least one inch to forty feet, indicating the property lines of the parcel upon which the use is proposed; any existing or proposed structures; parking areas and other built-upon areas; and surface water drainage. The site plan shall be neatly drawn and indicate the north point, name and address of the person who prepared the plan, date of the original drawing, and an accurate record of any later revisions. (b) A complete and detailed description of the proposed variance, together with any other pertinent information that the applicant feels would be helpful to the Watershed Review Board in considering the application. (c) Evidence or proposed witness testimony that tends to support a finding that each of the factors listed in subsection three below are met. (2) The Watershed Administrator shall notify in writing each local government having jurisdiction in the watershed and the entity using the water supply for consumption. Such notice shall include a description of the variance being requested. Local governments receiving notice of the variance request may submit comments to the Watershed Administrator before a RANDOLPH COUNTY UNIFIED DEVELOPMENT ORDINANCE PAGE 337 F. ARTICLE 800: WATERSHED PROTECTION ORDINANCE 1779 decision by the Watershed Review Board. Such comments shall become a part of the record of proceedings of the Watershed Review Board. (3) Before the Watershed Review Board may grant a variance, it shall make the following three findings, which shall be recorded on the permanent records of the case, and shall include the factual reasons on which they are based: (a) There are practical difficulties or unnecessary hardships in the ways of carrying out the strict letter of the Ordinance. To determine that there are practical difficulties or unnecessary hardships, the Board must find the five following conditions exist: (i) If he complies with the provisions of the Ordinance, the applicant can secure no reasonable return from, nor make reasonable use of, his property. Merely providing that the variance would permit a greater profit to be made from the property will not be considered adequate to justify the Board in granting a variance. Moreover, the Board shall consider whether the variance is the minimum possible deviation from the terms of the Ordinance that will make possible the reasonable use of his property. (ii) The hardship results from the application of the Ordinance to the property rather than from other factors such as deed restrictions or other hardships. (iii) The hardship is due to the physical nature of the applicant's property, such as its size, shape, or topography, which is different from that of neighboring property. RANDOLPH COUNTY UNIFIED DEVELOPMENT ORDINANCE PAGE 338 4o�Mii..Mo9Jy sZf ARTICLE 800 WATERSHED PROTECTION ORDINANCE (iv) The hardship is not the result of the actions of an applicant who knowingly or unknowingly violated the Ordinance, or who purchases the property after the effective date of the Ordinance, and then comes to the Board for relief. (v) The hardship is peculiar to the applicant's property, rather than the result of widespread conditions. If other properties are equally subject to the hardship created by the restriction, then granting a variance would be a special privilege denied to others and would not promote equal justice. (b) The variance is in harmony with the general purpose and intent of the Ordinance and preserves its spirit. (c) In the granting of the variance, public safety and welfare have been assured and substantial justice has been done. The Board shall not grant a variance if it finds that doing so would in any respect impair the public health, safety, or general welfare. (4) In granting the variance, the Board may attach thereto such conditions regarding the location, character, and other features of the proposed building, structure, or use that relate to the purpose and standards of this Ordinance. If a variance for the construction, alteration, or use of the property is granted, such construction, alteration, or use shall be per the approved site plan. (5) The Watershed Review Board shall refuse to hear an appeal or an application for a variance previously denied if it finds that there have been no substantial changes in conditions or circumstances bearing on the appeal or application. (6) A variance issued under this section shall be considered a Watershed Protection Permit and shall expire if a building permit or Watershed Occupancy Permit for such use is not RANDOLPH COUNTY UNIFIED DEVELOPMENT ORDINANCE PAGE 339 "^ } ARTICLE 800:WATERSHED PROTECTION ORDINANCE d a: 1779 obtained by the applicant within six months from the date of the decision. (7) If the application calls for the granting of a major variance, and if the Watershed Review Board decides in favor of granting the variance, the Watershed Review Board shall prepare a preliminary record of the hearing with all deliberate speed. The preliminary record of the hearing shall include: (a) The variance application; (b) The hearing notices; (c) The evidence presented; (d) Motions, offers of proof, objections to evidence, and rulings on them; (e) Proposed findings and exceptions; (f) The proposed decision, including all conditions proposed to be added to the permit. The preliminary record shall be sent to the Environmental Management Commission for its review. C. SUBDIVISION APPROVAL See Article 800, Section 802. D.

Terms used in this Rule shall be defined in Rule .0610 of 15A NCAC 02B. B. APPLICABILITY This Rule shall apply to landowners and other persons including Randolph County, State, and federal entities conducting activities within the riparian buffers as described in Item (C) of this Rule in the Randleman Lake Watershed. C. BUFFERS PROTECTED The following minimum criteria shall be used for identifying regulated riparian buffers: (1) Surface water shall be subject to this Rule if the feature is approximately shown on any of the following references, or if there is other site-specific evidence that indicates to the Authority the presence of waters not shown on any of these references: (a) The United States Geological Survey's National Map, available online at https://www.usgs.gov/core-science- systems/national-geospatial-program/national- map; (b) The most recent version of the published manuscript of the soil survey map that shows stream layers prepared by the Natural Resource Conservation Service of the United States Department of Agriculture; or (c) Other maps approved by the North Carolina Environmental Management Commission as more accurate than those identified in Sub-item (C) (1) (a) and (C) (1) (b) of the Rule. Other RANDOLPH COUNTY UNIFIED DEVELOPMENT ORDINANCE PAGE 341 volt..Mo9Jy Qom,, .R o'• Y ARTICLE 800: WATERSHED PROTECTION ORDINANCE 1779 maps shall use a hydrography dataset developed using hydrography specifications and standard metadata approved by the Geographic Information Coordinating Council (GICC) and maintained on a GICC list of the best available hydrography. Edits, deletions, and additions to the hydrography dataset shall follow GICC-approved standards and specifications, per stewardship governance. Other maps shall have their hydrography dataset and procedures for edits, deletions, and additions reviewed and approved by the GICC. Other maps shall be submitted to the Division for review and recommendation to the North Carolina Environmental Management Commission. Before recommendation to the North Carolina Environmental Management Commission, the Division shall issue a thirty-day public notice through the Division's mailing list under 15A NCAC 02H .0503. Division staff shall present recommendations including comments received during the public notice period to the North Carolina Environmental Management Commission for a final decision. Maps approved under this sub-item shall not apply to projects that are existing and ongoing within the meaning of this Rule as set out in Item (F) of this Rule; (2) This Rule shall apply to activities conducted within fifty-foot- wide riparian buffers directly adjacent to surface waters in the Randleman Lake Watershed (e.g., intermittent, and perennial streams, lakes, reservoirs, and ponds) excluding wetlands; (3) Wetlands adjacent to surface waters or within fifty feet of surface waters shall be considered as part of the riparian buffer but are regulated under 15A NCAC 02H .0506; (4) Stormwater runoff from activities conducted outside the riparian buffer shall comply with Item (I) of this Rule; (5) Riparian buffers protected by this Rule shall be measured under Item (H) of this Rule; (6) A riparian buffer may be exempt from this Rule as described in Items (E), (F), and (G) of this Rule; and RANDOLPH COUNTY UNIFIED DEVELOPMENT ORDINANCE PAGE 342 .o�Mlt.M09J-. o,, y , s�) ARTICLE 800 WATERSHED PROTECTION ORDINANCE (7) No new clearing, grading, or development shall take place, nor shall any new building permits be issued in violation of this Rule. D. ON-SITE DETERMINATION When a landowner or other affected part believes that the maps listed in Sub-Item (C) (1) of this Rule have inaccurately depicted surface waters or the specific origination point of a stream, or the specific origination point of the steam is in question or unclear, he or she shall request the Authority to make an on-site determination. On-site determinations shall be made by Authority staff that is certified under NCGS 143-214.25A. Registered Foresters under Chapter 98B of the General Statutes who are employees of the North Carolina Forest Service of the Department of Agriculture and Consumer Services can make on-site determinations for forest harvesting operations and practices. Randolph County may accept the results of an on-site determination made by other parties who have completed the Division's Surface Water Identification Training Certification course, its successor, or other equivalent training curriculum approved by the Division. On-site determinations shall expire five years from the date of the determination. Any disputes over on-site determinations shall be referred to the Director in writing within sixty calendar days of written notification from the Authority. The Director's determination is subject to review as provided in NCGS 150B Articles 3 and 4. E. EXEMPTION BASED ON ON-SITE DETERMINATION Surface waters that appear on the maps listed in Sub-Item (C) (1) of this Rule shall not be subject to this Rule if an on-site determination shows that they fall into one of the following categories: (1) Ditches and manmade conveyances including manmade stormwater conveyances, other than modified natural streams unless the ditch or manmade conveyance delivers untreated stormwater runoff from an adjacent source directly to an intermittent or perennial stream; (2) The absence on the ground of a corresponding perennial waterbody, intermittent water body, lake, reservoir, or pond; (3) Ephemeral streams; and (4) Manmade ponds and lakes that are not fed by an intermittent or perennial stream or do not have a direct discharge point to an intermittent or perineal stream.
