It is referred to herein as "this ordinance." 53-102 AUTHORITY The City of Roxboro is authorized to adopt this ordinance pursuant to North Carolina law, including but not limited to Article 14, Section 5 of the Constitution of North Carolina; North Carolina General Statutes Chapter 143-214.7 and rules promulgated by the Environmental Management Commission thereunder; Chapter 143-215.6A; Chapter 153A- 454; Chapter 160A, §§ 174, 185, 459; as well as Chapter 11 3A, Article 21, Part 6, Floodway Regulation. 53-103 FINDINGS It is hereby determined that: Development and redevelopment alter the hydrologic response of local watersheds and increases stormwater runoff rates and volumes, flooding, soil erosion, stream channel erosion, nonpoint and point source pollution, and sediment transport and deposition, as well as reducing groundwater recharge; These changes in stormwater runoff contribute to increased quantities of water -borne pollutants and alterations in hydrology that are harmful to public health and safety as well as to the natural environment; and These effects can be managed and minimized by applying proper design and well -planned controls to manage stormwater runoff from development sites. Further, the Commission has identified Falls of Neuse reservoir, a water supply reservoir, as nutrient sensitive waters; has identified all or a portion of the reservoir as impaired waters under the federal Clean Water Act due to exceedances of the chlorophyll a standard; and has promulgated rules (the "Falls Rules") to reduce the average annual loads of nitrogen and phosphorus delivered to Falls Reservoir from all point and nonpoint sources of these nutrients located within its watershed, including stormwater from new development in this jurisdiction; Further, the Federal Water Pollution Control Act of 1972 ("Clean Water Act") and federal Phase 11 Stormwater Rules promulgated under it, as well as rules of the North Carolina Environmental Management Commission promulgated in response to federal Phase II requirements, compel certain urbanized areas, including this jurisdiction, to adopt the minimum stormwater controls such as those included in this ordinance. Therefore, the City of Roxboro City Council establishes this set of water quality and quantity regulations to meet the requirements of state and federal law regarding control of stormwater runoff and discharge for development. 53-104 PURPOSE The purpose of this ordinance is to protect, maintain and enhance the public health, safety, environment and general welfare by establishing minimum requirements and procedures to control the adverse effects of increased stormwater runoff, nitrogen and phosphorus in stormwater runoff and nonpoint and point source pollution associated with new development and redevelopment in the City of Roxboro corporate limits. It has been determined that proper management of construction -related and post -development stormwater runoff will minimize damage to public and private property and infrastructure; safeguard the public health, safety, and general welfare; and protect water and aquatic resources. This ordinance seeks to meet its general purpose through the following specific objectives and means: 1. Establishing decision -making processes for development that protects the integrity of watersheds and preserve the health of water resources; 2. Requiring that new development and redevelopment maintain the pre -development hydrologic response in their post -development state for the applicable design storm to reduce flooding, streambank erosion, nonpoint and point source pollution and increases in stream temperature, and to maintain the integrity of stream channels and aquatic habitats; 3. Establishing rru*n1mum post -development stormwater management standards and design criteria for the regulation and control of stormwater runoff quantity and quality; 4. Establishing design and review criteria for the construction, function, and use of structural stormwater BMPs that may be used to meet the minimum post - development stormwater management standards; 5. Encouraging the use of better management and site design practices, such as the use of vegetated conveyances for stormwater and the preservation of greenspace, riparian buffers and other conservation areas to the maximum extent practicable; 6. Establishing provisions for the long-term responsibility for and maintenance of structural and nonstructural s/orm2pater BMPs to ensure that they continue to function as designed, are maintained appropriately, and pose no threat to public safety; 7. Establishing administrative procedures for the submission, review, approval and disapproval of stormwatermanagementplans, for the inspection of approved projects, and to assure appropriate long-term maintenance. 8. Controlling illicit discharges into the municipal separate stormwater gstem. 9 53-105 APPLICABILITY AND JURISDICTION (A) General Beginning with and subsequent to its effective date, this ordinance shall. be applicable to all development and redevelopment, including, but not limited to, site plan applications, subdivision applications, and grading applications, within the corporate and extra territorial jurisdictional limits unless exempt pursuant to this ordinance. (B) Exemptions Single family and duplex residential and recreational development and redevelopment that cumulatively disturbs less than one half acre in the Falls Lake Watershed or one (1) acre within the rest of the City's jurisdiction or does not increase the built upon area of the site and is not part of a lar ger commonplan of development or sale is exempt from the provisions of this ordinance. This exemption does not exist for the Water Supply Watershed Standards within the City's jurisdiction. Commercial, industrial, institutional, multifamily residential or local government development and redevelopment that cumulatively disturbs less than 12,000 square feet in the Falls Lake Watershed or one (1) acre within the rest of the City's jurisdiction or does not increase the built upon area of the site and is not part of a larger commonplan of development or sale is exempt from the provisions of this ordinance. This exemption does not exist for the Water Supply Watershed Standards within the City's jurisdiction. Development and redevelopment that disturbs less than the above thresholds are not exempt if such activities are part of a IaTer commonplan of development or sale and the larger common plan exceeds the relevant threshold, even though multiple, separate or distinct activities take place at different times on different schedules. Development that is exempt from permit requirements of Section 404 of the federal Clean Water Act as specified in 40 CFR 232 (primarily, ongoing farming and forestry activities) are exempt from the provisions of this ordinance. Redevelopment projects that are exempt from this ordinance must provide equal or greater stormwater control than the previous development. This ordinance shall not require private property owners to install new or increased stormwater controls for (i) preexisting development or (ii) redevelopment activities that do not remove or decrease existing stormwater controls. When a preexisting development is redeveloped, either in whole or in part, increased stormwater controls shall only be required for the amount of impervious surface being created that exceeds the amount of impervious surface that existed before the redevelopment. AU subdivisions must be reviewed by the Stormwater Administrator prior to recording by the Register of Deeds to determine whether or not the property/project is subject to this ordinance. (C) No Development or Redevelopment Until Compliance and Permit No development or redevelopment shall occur except in compliance with the provisions of this ordinance or unless exempted. No development or redevelopment for which a permit is required pursuant to this ordinance shall occur except in compliance with the provisions, conditions, and limitations of the permit.

One re -submittal of a revised application may be submitted without payment of an additional permit review fee. Any re -submittal after the first re -submittal shall be accompanied by a permit review fee additional fee, as established pursuant to this ordinance. 53-203 APPLICATIONS FOR APPROVAL (A) Concept Plan and Consultation Meeting Before a stormwater management permit application is deemed complete, the Stormwater Administrator or developer may request a consultation on a concept plan for the post -construction stormwater management system to be utilized in the proposed development project. This consultation meeting should take place at the time of the preliminary plan of subdivision or other early step in the development process. The purpose of this meeting is to discuss the stormwater management measures necessary for the proposed project, as well as to discuss and assess constraints, opportunities and potential approaches to stormwater management designs before formal site design engineering is commenced. Local watershed plans and other relevant resource protection plans should be consulted in the discussion of the concept plan. To accomplish this goal, the following information should be included in the concept plan, which should be submitted in advance of the meeting: (1) Existing Conditions / Proposed Site Plans Existing conditions and proposed site layout sketch plans, which illustrate at a minimum: existing and proposed topography; perennial and intermittent streams; mapping of predominant soils from soil surveys (if available); stream and other buffers and features used in designing buffers and meeting any applicable buffer requirements; boundaries of existing predominant vegetation; proposed limits of clearing and grading; and location of existing and proposed roads, buildings, parking areas and other impervious surfaces. (2) Natural Resources Inventory A written or graphic inventory of natural resources at the site and surrounding area as it exists prior to the commencement of the project. This description should include a discussion of soil conditions, forest cover, geologic features, topography, wetlands, and native vegetative areas on the site, as well as the location and boundaries of other natural feature protection and conservation areas such as lakes, ponds, floodplains, stream buffers and other setbacks (e.g., drinking water well setbacks, septic setbacks, etc.). Particular attention should be paid to environmentally sensitive features that provide particular opportunities or constraints for development and stormwater management. 18 (3) Stormwater Management System Concept Plan A written or graphic concept plan of the proposed post -development stormwater management system including: preliminary selection and location of proposed engineered stormwater controls; low -impact design elements; location of existing and proposed conveyance systems such as grass channels, swales, and storm drains; flow paths; location of floodplain/floodway limits; relationship of site to upstream and downstream properties and drainages; and preliminary location of any proposed stream channel modifications, such as bridge or culvert crossings. Stormwater Management Permit Application The stormwater management permit application shall detail how post -development stormwater runoff will be controlled and managed and how the proposed project will meet the requirements of this ordinance, including Section 3, Standards.
