The total housing units was 8,686, with 3,354 being permanently occupied and the remaining 5,332 being vacant recreational, rental, or occasional use units. The Town estimates the seasonal population to be 3.2 times the permanent population, which would be 27,795 for the year 2010. The maximum number of persons residing, vacationing, and visiting the Town of Oak Island in any one day, e.g., fourth of July, has been as high as 35,000. 1.2 Growth Rate: In 2000, the Town of Oak Island population was 6,571. According to the US Census Bureau, the 2010 population was 6783, for an annual growth rate of 3.2%. 1.3 Jurisdictional and MS4 Area: The jurisdictional town boundaries encompass approximately 19.91 square miles. The MS4 service area is approximately 10 square miles. 1.4 MS4 Conveyance System: There are 127 stormwater discharge locations identified within the Town of Oak Island, 59 of which discharge into the Davis Canal. A few of these are point discharges, but most are sheet flow discharges from the streets leading to the canal. The largest point discharge is located at the intersection of E. Pelican Drive and SE 40th Street. Stormwater that drains to the ditches on Pelican Drive discharges into the Davis Canal. There is a series of pipes and ditches leading to 10 discharges into ponds located between SC ® 59`h Street and SE 7151 Street. Pipes and ditches leading to the Intracoastal Waterway convey the remaining discharges. Most of these discharges are 100 to 200 feet short of the waterway, thus providing some vegetative filtering before discharging into the waterway. There are 167 drop inlets, most of which are located at the eastern end of the Town, or what was the Town of Yaupon Beach. Also in the eastern part of the Town are two manholes located on McGlamery Street, which are for maintenance of an 18-inch corrugated metal pipe conveying stormwater to the marsh adjacent to the Intracoastal Waterway. The Town has 13.3 miles of storm drainage pipe, including road culverts, and 19.7 miles of designated storm drainage ditches. The conveyance system is maintained by the 'rown's Public Works department, which includes periodic cleaning of roadside swales, catch basins and seeding eroded areas to ensure the open portions of the system remain vegetated. 1.5 Land Use Composition: Estimated percentage of the MS4 area under residential, commercial, industrial, and open space land use.

(Ord. of 8-13-2002, § 2.0) Sec. 18-703. - Findings of facts. The town council finds that the discharge of non-stormwater drainage to waters of the state and to the municipal storm drainage system could have significant adverse impact upon health, safety, and welfare of the community. More specifically: (1) Illicit stormwater discharges carry pollutants into receiving water bodies, degrading water quality and effect in closures of shell fishing waters. (2) A nutrient such as phosphorus or nitrogen accelerates eutrophication of receiving waters, adversely affecting flora and fauna. (3) Improper connection to the storm drain system and to waters of the state adversely impacts quality of receiving waters. (4) Septic tank discharges from non -compliant systems, washing machine discharges, and illegal dumping into the stormwater drains are examples of illicit discharges. (5) The town must have the authority to deter and/or stop illicit discharges to stormwater drains and ditches. (6) Substantial economic losses result from these adverse impacts on community waters. S(7) Illicit discharges to water bodies diminish their capacity to naturally process runoff nutrients, Oak Island, North Carolina, Code of Ordinances Page 5 of 15 PART II - CODE OF ORDINANCES Chapter 18 - LAND USE DEVELOPMENT ARTICLE VI. - ILLICIT STORMWATER DISCHARGE 9 thereby harming flora and fauna. (8) Increase of illicit discharge to waters can percolate into the soil, thereby decreasing groundwater quality. (9) Improperly managed stormwater systems can decrease the quality of property and human life. (10) Improperly managed stormwater drainage systems can interfere with the maintenance of optimum estuarine areas and biological productivity. (11) Many future problems can be avoided if land is developed in accordance with an illicit stormwater discharge ordinance. (Ord. of 8-13-2002, § 3.0) Sec. 18-704. - Objectives.

The Mown reserves the option to require submittal of a stormwater management application prepared by a licensed engineer For any land use project. An application must be submitted to Conurlurllty Development Services that describes how the stormwater runoff will be controlled and managed to meet Town requirements. If the Stormwater Administrator finds that the application complies with the standards of the Town ordinance, the application will be approved. Additional conditions may be included as part of the approval. The application must include a completed Stormwater Management Worksheet (Appendix L) and a site plan or survey of the property showing the proposed stormwater management plan, including, I . Size and location of any building or other structures 2. Sire and location of all driveways and walkways 3. Location ofseptic tank and drain field, ifapplicable 4. Location and dimensions of drywells or drip line trenches (or alternative stormwater management system) 5. Show location of sediment fence. SEDIMENT MUST BE Rl?TAINED ON SITE 6. Other site specific features if required by Town of Oak Island — Community Development Services • If the project meets or exceeds any of the three (3) conditions listed below, the stormwaler management system must be stamped, signed, and dated by a licensed professional engineer or surveyor. l . Impervious surface area of'30% or greater (See Stormwater Mana cement Worksheet, Appendix E) 2. Addition of 6" or more of uncompressed fill material 3. Grading resulting in a slope of 5% (6" of fail over a 10' horizontal distance or greater) If the project does not exceed any of the above listed conditions and is located in an area that is not governed by a State issued stormwater permit, the owner, contractor, or authorized agent may prepare the stormwater management application using the standard method outlined below or another method that complies with State and local requirements. Projects located in an area governed by a state issued stormwater permit must comply with those requirements. The stormwater management application must be approved before any work begins. • The Standard Method • The standard method requires routing roof runoff from ail structures into infiltration devices (e.g., downspout drywells or drip line trenches) and installation of a driveway channel with drywells. Drywells and drip line trenches are small, excavated pits, filled with stone or gravel that temporarily stores stormwater runoff until it infiltrates (soaks) into the surrounding soil. These devices lielp protect our tidal creeks and estuaries by infiltrating the stormwater runoff on land thereby decreasing pollution and lessening flooding impacts. • Raised Slab Homes, Slab on Grade homes, Crawl space homes, and filing homes with habitable enclosures under must have gutters with downspouts routed into appropriately sized pits as described in Appendix 13. When gutter downspouts are routed into drywells or other stormwater management device, a bypass should be installed oil the downspout. The bypass will allow water to escape in the event rainfall in excess of the design criteria is experienced preventing overflow water from backing up into downspouts. • filing homes with no enclosures may utilize a continuous drip line infiltration trench under all eves as described in Appendix F. • Size of drywells: All infiltration devices must comply with 'Town approved sizing and design guidelines. • Sediment must be retained on site. • The following site conditions must be met in order for infiltration devices to be installed. 1. A site on the property must be available for the drywells and/or drip -line trenches with required setbacks from structure foundations, water wells or septic drain fields. Minimum horizontal setbacks from a septic system are as follows: upslope 10 feet, side slope 15 feet, down slope 25 feet. Minimum setback from foundations is 5 feel. • 2. Soils must be sufficiently permeable. 3. Water table depth allows for construction of drywells. if the seasonal water table is within 12" of the bottom of the bottom of the excavation, alternative stormwater control devices are recommended. Contact the Stormwater Administrator (910.201.8008) for more information. • If site conditions such as slope, soil type, high ground water levels exist that prevent any of the above conditions from being met or an alternative method of stormwater management is desired, the stormwater management application must describe the method to be used. • All infiltration devices (e.g., downspout drywell, drip line trenches, driveway drywells, etc.) must be filled with clean AASI-ITO #57 Stone (or equivalent washed drain rock -- 0.75-3.0 inches in diameter). • To extend the useful life of the system, filter fabric must line sides and top of. the infiltration device to prevent fine soils from migrating into the drain rock. • Infiltration systems should be equipped with cleanout sumps or downspout screens to collect leaves, needles, roof grit and other debris or leaf guards should be installed on gutters to prevent leaves and other plant material from entering downspouts and clogging the dry well. • Infiltration devices connected to downspouts must have a four (4) or six (f) inch perforated pipe, placed in the upper portion of the rock fill and extending the length of the trench. Any number of drywells/trenches may be used, provided the volume of voids in each drywell is adequate to receive the rain runoff from that portion of roof.area being routed to it. • Community Development Services must inspect all infiltration devices prior to certifying; the • structure for occupancy. Do not backfill over any underground installation until it has been inspected. • The applicant/homeowner shall maintain in good condition all stormwater practices constructed in accordance with the stormwater ordinance.

It is hereby determined that: Development and redevelopment alter the hydrologic response of local watersheds and increase 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 Federal Water Pollution Control Act of 1972 ("Clean Water Act") and Federal Phase II Stormwater Rules promulgated under it, as well as rules of the state environmental management commission promulgated in response to federal phase II requirements, compel certain urbanized areas, including this jurisdiction, to adopt minimum stormwater controls such as those included in this article. Therefore, the Town of Oak Island establishes this set of water quality and quantity regulations to meet the requirements of the state and federal law regarding control of stormwater runoff and discharge. (Ord. of 3-10-2009) Sec. 18-654. - Purpose. (a) General. The purpose of this article 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 post -development stormwater runoff and nonpoint and point source pollution associated with new development and redevelopment. 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. (b) Specific. This article 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 predevelopment hydrologic response in their post -development state as nearly as practicable for the applicable design storm to reduce flooding and erosion, nonpoint and point source pollution and increases in stream or tidal creek temperature, and to maintain the integrity of stream channels, aquatic habitats and estuaries; (3) Establishing minimum 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 Oak Island, North Carolina, Code of Ordinances Page 2 of 23 PART II - CODE OF ORDINANCES Chapter 18 - LAND USE DEVELOPMENT ARTICLE V. - STORMWATER MANAGEMENT DIVISION 6. -DEFINITIONS 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 green space, 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 stormwater 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 stormwater management plans, for the inspection of approved projects, and to assure appropriate long-term maintenance.

Purpose of Manual The purpose of this Administrative Manual is to provide guidance to the general public for the effective and efficient implementation and administration ofthe Phase 11 Stormwatcr Ordinance (referred to as the Stornnvater Ordinance). The Administrative Manual includes application requirements and forms, maintenance agreements, criteria for recordation of documents, inspection reports, requirements for submittal of bonds. Copies may be viewed at Community Development Services or by contacting Public Works — Stormwater Director at 910.201, 9008. 2. Impacts of Stormwater on Water Quality Stormwater runoff from developed areas is a source of water pollution and water quality degradation. Development and redevelopment alter the hydrologic response ofthe lown's watersheds and increase stormwater runollrates and volumes, flooding, soil erosion, stream channel erosion, nonpoint source pollution, and sediment transport and deposition, as well as reducing groundwater recharge. • These changes in stormwater runo fT contribute to increased quantities of Pollutants and alterations in hydrology that are harmful to public health and safety as well as to the natural environment. These efTects can be managed and minimized by applying proper design and we] l-planned-contro Is to manage stormwater runoff. 3.

Concept Plan and Consultative 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 early in the development process. The purpose ofthe consultative meeting, is to discuss stormwater 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. The recommended content ofthe concept plan is outlined in the Stormwater Ordinance and should be submitted in advance ofthe meeting. 8. Stormwater Management Permit Application Submission and Review A stormwater permit is required for all development and redevelopment unless exempt as defined by the Stormwater Ordinance (e.g., single-family or duplex residences that will add 10,000 square feet or less of built upon area). All applications shall be submitted to Community Development Services by the landowner or the landowners duly authorized agent. An application shall be considered as timely submitted only when it contains all elements of complete application in accordance with the Stormwater Ordinance. If the Stormwater Administrator finds that an applicat ion is incomplete, the applicant shall be notified of the deficient elements and shall be provided with an opportunity to submit a complete application. Within twenty (20) working days after a complete application is submitted, the Stormwater Administrator shall review the application and determine whether the application complies with the standards. If the Stormwater Administrator finds that the application complies with the standards of this ordinance, the Stormwater Administrator shall approve the application. The Stormwater Administrator may impose conditions of' approval as needed to ensure compliance with this ordinance. The conditions shall be included as part of the approval. I f the Stormwater Administrator finds that the application fails to comply with the standards of this ordinance, the Stormwater Administrator shall notify the applicant and shall indicate how the application fails to comply. The applicant shall have an opportunity to submit a revised application. A complete revised application shall be reviewed by the Stormwater Administrator within ten (10) working days after its re -submittal and shall be approved, approved with conditions or disapproved. If a revised application is not re- submitted within thirty (30) calendar days from the date the applicant was notified, the 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 for a new submittal. One re -submittal of a revised application may be submitted without payment ofan additional permit review fee.

Final Plat Recordation Enibrceable restrictions on property usage are required to run with the land to ensure that future development and redevelopment maintains the site in compliance with the Stormwater Ordinance. This is achieved through specific notations on final plats as described below, which shall be reviewed and approved by the Stormwater Administrator prior to recordation. To the extent that a lot is subject to these restrictions, those restrictions that show up on the recorded final plat shall be picked up by the surveyor and shown on the survey for the lots given to the purchasers at the time ofelosing. In this way, the property owner shall be 0 made aware of the restrictions and shall maintain the site in compliance with the Stormwater Ordinance. The following shall appear on all plats: Location of all designated "Undisturbed Open Space Areas". The location and name of major streams and buffer boundaries including the delineation of each buffer zone and the top of the stream bank (field located).

The designer of the stormwater management measures and plans shall certify, under seal, that the as - built stormwater measures, controls, and devices are in compliance with the approved stormwater management plans and designs and with the requirements of the Stormwater Ordinance. Final approval by the Stormwater Administrator shall occur before the release ofany performance securities. 16. Stormwater Management flan Requirements for Single-Family/Duplex Development and Redevelopment exempt from the Post -Construction Stormwater Ordinance All development and redevelopment of single-family or duplex residences that will add 10,000 square feet or less of built upon area are exempt from obtaining an individual stormwater perniit except all such development must provide appropriate control systems that are any combination of infiltration systems, hioretention systems or other system designed in accordance with State Standards. The systems must control and treat the runoff.from all surlaces generated by one and one-half inches of rainfall or less (Stormwater Management Ordinance for Oak Island, North Carolina Sec. f 8-655) from all impervious surfaces on site. All application must be submitted to Community Development Services that describes in detail how the stormwater runotrwill be controlled and managed to meet this requirement. If the Stormwater Administrator finds that the application complies with the standards of the Town ordinance, the Stormwater Administrator will approve the application. The Stormwater Administrator may impose conditions of'approval as needed to ensure compliance with the Town stormwater ordinance. The conditions will be included as part of the approval. The purpose of these guidelines is to prevent flooding and the degradation of water quality related to stormwater runofl'and soil erosion. The application must include a completed Stormwater Management Worksheet (Appendix E) and a site plan of -the property showing details of the proposed stormwater management device(s). I . Size and location of any building or other structures 2. Location of'septic tank and drain field if applicable 3. Show proposed infiltration system (or alternative stormwater management system) including the location, size, and volume of storage provided. Draw arrows showing which impervious surfaces (including roof areas) will be routed into each infiltration device. 4. Show location of erosion and sedimentation control devices 5. Other site specific features if required by Town of Oak Island — CoiYrnuinity Development Services The stormwater management application must be approved before any work begins. If the project meets or exceeds any of the three (3) conditions listed below, the stormwater management system must be stamped, signed, and dated by a licensed professional engineer or surveyor. l . 13UA of 30% or greater (See Appendix I-L, Stormwater Management Worksheet) 2. Addition of -six (6) inches or more of uncompressed fill rnatcrial 3. Grading resulting in a slope of'5% (6 inches of fall over a 10 ft. horizontal distance or greater) f the project does not exceed any ofthe above listed conditions and is located in an area that is not governed by a state issued stormwater permit, the owner, contractor, or authorized agent may prepare the stormwater management application using the standard method outlined below or another method that complies with State and local requirements. Projects located in an area governed by a state issued stormwater permit must comply with those requirements. The Dry Well Method The standard method requires routing roof runofffrom all structures into infiltration devices (e.g., downspout drywells or drip line trenches) and installation ofdriveway channels with infiltration devices. All infiltration devices must comply with Town approved sizing and design guidelines. The following site conditions must be met in order for infiltration devices to be installed. A site on the property must be available for the infiltration device that does not conflict with any septic drain field, structure foundations, or water well. Minimum horizontal setbacks from a septic system are as follows: upslope 10 feet, side slope 15 feet, down slope 25 feet. Infiltration devices must have a minimum setback of 5 feet from foundations. Soils must be sufliciently permeable. Water table depth allows for construction ofdrywells. If this is not possible, other alternative stormwater control devices are recommended. Contact the Stormwater Administrator for more intbrmation. The site plan minimizes the amount of pavement, concrete, driveways and other impervious surfaces to the maximum extent possible. If site conditions such as slope, soil type, high ground water levels exist that prevent any ofthe above conditions from being met or an alternative method of stormwater management is desired, the stormwater management application must describe the method to be used. All infiltration devices (e.g., downspout drywell, drip line trenches, driveway drywells, etc.) must be filled with clean AASHTO #57 Stone (or equivalent washed drain rock — 0.75-3.0 inches in diameter). To extend the useful life ofthe system, filter fabric must line sides and top ofthe infiltration device to prevent fine soils from migrating into the drain rock and be equipped with cleanout sumps or screens to collect leaves, needles, roofgrit and other debris. Infiltration trenches connected to downspouts must have a four (4) or six (6) inch perforated pipe, placed in the upper portion ofthe rock Jill and extending the length ofthe trench (Alternative methods may be approved by the Stormwater Administrator). Any number of drywells/trenches may be used, provided the volume of voids in each drywell is adequate to receive the rain runoff from that portion of roof area being routed to it. Refer to Appendix E, Stormwater Management Worksheet, for sizing and design guidelines. Community Development Services must inspect all infiltration devices prior to certifying the structure for occupancy. Do not backfill over any underground installation until it has been inspected. The applicant/homeowner shall maintain in good condition all stormwater practices constructed in accordance with the stormwater ordinance. The above guidelines are intended to simplify and expedite the review and approval of stormwater management applications and are not necessarily all- inclusive. The Town reserves the option to require submittal of a stormwater management application prepared by a licensed engineer for any land use project. • E 0 Appendix E: Town Oak Island Vegetation Management Program Ordinance 66 • 0 PART li - CODE OF ORDINANCES Chapter 32 - VEGETATION ARTICLE Ill. - VEGETATION MANAGEMENT PROGRAM ARTICLE III. - VEGETATION MANAGEMENT PROGRAM Sec. 32-71. - Purpose of article.
