In addition, the Legislature of the State of North Carolina has, in Chapter 143, Article 21 of the North Carolina General Statutes, entitled Water and Air Resources, directed local governmental units to adopt regulations designed to promote the public health, safety, and general welfare pursuant to the more specific requirements set forth in 15A NCAC 213 .0100, 15A NCAC 213 .0200, and in the Jordan Water Supply Watershed Nutrient Management Strategy Rules, 15A NCAC 213 .0262 through .0273 and .0311(p). Also pursuant to the Federal Water Pollution Control Act of 1972, federal Phase II Stormwater rules promulgated under it, and NCGS 143-215.1 and S.L. 2006-246, the Town is required to obtain a Phase II National Pollutant Discharge Elimination System (NPDES) permit for stormwater management for its municipal separate storm sewer system and to adopt, among other things, requirements and procedures to control the adverse effects of increased post development stormwater runoff and nonpoint and point source pollution associated with new development and redevelopment. (Additional specific purposes may be found in the Swift Creek Land Management Plan and the 2045 Land Use Map Update.) In furtherance of these goals and under such authorities, the Town of Apex promulgated this Sec. 6.1 Watershed Protection Overlay Districts. 6.1.2 Primary and Secondary Watershed Protection Overlay Districts Except for those lands and uses exempted pursuant to Sec. 6.1.3 Exemptions, the Watershed Protection Overlay Districts shall encompass all lands within the Town of Apex and its extraterritorial jurisdiction as established in Sec. 1.2.2 Authority to Regulate Zoning, Subdivision And Building Practices in ETJ. The boundaries for the Town's extraterritorial jurisdiction area (hereinafter "ETJ") are delineated on the Town of Apex's "Official Zoning District Map." A copy of this map shall be on record in the office of the Town Clerk and in the Planning Department for inspection by the general public during normal business hours. The Town and its ETJ shall be divided into two (2) districts for the purpose of watershed protection. The Primary Watershed Protection District shall consist of all lands identified by the state as water supply watershed protected areas. The Secondary Watershed Protection District shall consist of the remainder of lands within the Town and its ETJ. These two (2) districts shall be identified on the Town of Apex's "Watershed Protection Overlay District Map." A copy of this map shall be on record in the office of the Town Clerk and in the Planning Department for inspection by the general public during normal business hours. All subsequent changes to the area that is identified by the state as water supply watershed protected area are herein adopted by reference, and the Planning Department shall cause such changes to be reflected on said map. A portion of the Jordan Lake Watershed, which consists of all lands and waters draining to the B. Everette Jordan Reservoir, is located within the Town's Primary Watershed Protection District and a portion is located within the Secondary Watershed Protection District as also depicted on the Town's Watershed Protection Overlay District Map. The Town shall also maintain a "Stormwater Control Measures (SCMs) Map" of the Town and its ETJ that depicts the geographic location of all the SCMs approved under Sec. 6.1 July 21, 2020 Article 6 - Page 1 Article 6 / Overlay Districts Sec. 6.1 / WATERSHED PROTECTION OVERLAY DISTRICTS Sec. 6.1.3 / Exemptions and the map shall be updated as necessary to accurately reflect the location of such structures.

A) Relationship to Resource Conservation Areas The area of land on a property that is located within the riparian buffer may be counted by the developer in accordance with Sec. 8.1.2 Resource Conservation Area, when calculating the amount of RCA that is required on that property by said Section. B) Measurement of Riparian Buffers The buffer width at a particular point along a stream shall be measured on a line perpendicular to a vertical line marking the top of the stream bank to the landward edge of the buffer. For ponds and lakes the buffer shall begin at the normal water level and extend landward on a line perpendicular to a vertical line marking the normal water level. 1) Additional Setbacks from Riparian Buffers All buildings shall be set back 10 feet and all vehicular use areas shall be set back five (5) feet from any riparian buffer. C) Classification of Surface Waters on Property Riparian buffers shall be maintained for all perennial and intermittent streams, lakes, and ponds as set forth in Sec. 6.1.6 Low -Density Development Option, and Sec. 6.1.7 High -Density Development Option of this Ordinance. Classifications of surface waters as perennial or intermittent streams, as ephemeral streams (a classification requiring no buffer under the requirements of Sec. 6.1 Watershed Protection Overlay Districts), or as a lake or pond shall be as indicated on the most recent version of the U.S.G.S. 1:24,000 (7.5 minute) scale topographic maps, the most recent version of the soil survey map prepared by the Natural Resources Conservation Service of the United States Department of Agriculture, or a map approved by the Geographic Information Coordinating Council and the Environmental Management Commission. In the event that there exists a discrepancy among any of these maps that would affect a required buffer, the classification requiring the most stringent buffer shall be applied. However, an alternative map approved by the Environmental Management Commission shall not be used for buffer delineation on projects that are existing and ongoing within the meaning of Sec. 6.1.11.J. July 21, 2020 Article 6 - Page 8 Article 6 / Overlay Districts Sec. 6.1 / WATERSHED PROTECTION OVERLAY DISTRICTS Sec. 6.1.11 / Riparian Buffers D) Appeals of Stream Classification Because the Neuse River is protected by a state-wide buffer program, which is managed by the NC DEQ, the authority to hear appeals of stream classifications for that portion of the Town of Apex and its ETJ that lies within the Neuse River Basin, which shall be indicated on the Town of Apex's "Watershed Protection Overlay District Map," rests within the sole jurisdiction of the NC DEQ unless the Town of Apex is delegated the authority to maintain its Neuse Buffer Program locally. Therefore, appeals of stream classifications shall be handled in the following manner: 1) Within the Neuse River Basin When any affected party within the Neuse River Basin believes that the maps have inaccurately depicted surface waters, he or she shall consult the NC DEQ as set forth in 15A N.C.A.C. 2B.0233(3). In the event that the Town of Apex is delegated the authority to maintain Neuse buffers locally, the Environmental Engineering Manager shall make decisions and interpretations regarding stream classifications in accordance with all applicable state criteria and the best available scientific information. Any disputes over such on -site determination shall be referred to the Director of the NC DEQ in writing. A determination of the Director as to the accuracy or application of the maps is subject to review as provided in Articles 3 and 4 of G.S. 150B. 2) Within the Jordan Lake Watershed When any affected party within the Jordan Lake Watershed believes that the maps have inaccurately depicted surface waters, the Environmental Engineering Manager, or his or her designee, shall make decisions and interpretations regarding stream classifications in accordance with the protocol in Sec. 6.1.11.D.4 and all applicable state criteria and the best available scientific information. Any disputes over such on -site determination made by the Town of Apex shall be referred to the Director of the NC DEQ in writing. A determination of the Director as to the accuracy or application of the maps is subject to review as provided in Articles 3 and 4 of G.S. 150B. 3) In All Remaining Areas Within Both the Primary Watershed Protection District and the Secondary Watershed Protection District In all remaining areas, the Environmental Engineering Manager, or his or her designee, shall make decisions and interpretations regarding stream classifications in accordance with the protocol in Sec. 6.1.11.D.4 and all applicable state criteria and the best available scientific information. Any person aggrieved by a decision of the Town regarding such on -site determination may appeal such decision to the Board of Adjustment. 4) Exemption Based On On -Site Determination A Town representative who makes an on -site stream classification shall have successfully completed the NC DEQ's Surface Water Identification Training Certification course, its successor, or other equivalent training curriculum approved by the NC DEQ. The specific origination point of a stream shall be established using the latest version of the Division publication, Methodology for Identification of Intermittent and Perennial Streams and Their Origins, available at https://deq.nc.gov/about/ divisions/water-resources/water-resources-permits/wastewater-branch/ 401-wetlands-buffer-permits/401-application-forms-help-documents or from the NC DEQ — 401 and Buffer Permitting Branch, or its successor.
