The NC Office of State Planning estimates that Laurel Park’s population as of July 1, 2008 is 2271. • Seasonal: Census 2000 listed Laurel Park with a seasonal population of 124. Laurel Park has several out of state/in state residents with second homes in Laurel Park. 1.2 Growth Rate: July 1, 1998 = 2064 2000 Census = 2027 July 1, 2008 = 2271 10 year population difference = 207 207/2064 = 10 % as ten year growth rate 10.0% / 10 = 1 % per year 1.3 Jurisdictional and MS4 Service Areas: Jurisdictional Area Total: 2.88 square miles MS4 Service Area: 2.61 square miles (removes DOT maintained road area) 1.4 MS4 Conveyance System: The Town of Laurel Park’s storm sewer system is mainly open drainage ways with a minimal amount of curb and gutter on local, state, and private roads. The Town maintains most roads within the community and the roadways drain into receiving wooded areas and/or streams directly. The State DOT maintains systems along the State Roads, which in Laurel Park includes a section of US 64W and several arterial roads. (Laurel Park’s State Powell Bill Map, July 1, 2009): There are private drives and small roadways that are both paved and unpaved that connect to Town and State roads and are maintained by owners. Most use open ditches. Town maintenance includes leaf pickup, garbage pickup, brush removal, street sweeping, and storm-drain clearance. Public Works staff routinely cleans out roadway and driveway culverts and storm drains as needed. Laurel Park’s Public Works Department currently maintains 8 full time employees. Town, state, and private systems channel water into ditches that flow into un-named tributaries leading into Shaw Creek, Wash Creek (Rainbow Lake, Temple Terrace Lake), Tonys Creek, North Fork Willow Creek, or Finley Creek. Several other un-named blue-line 3 streams indicated on the USGS Topographical Survey may hold or carry water into these creeks during periods of rain, but are usually dry. 1.5 Land Use Composition Estimates: • Residential 52 % • Commercial 7 % • Industrial 0 % • Open Space 41 % Total = 100 % Estimate Methodology for Land Use Estimates: ➢ Jurisdictional Area and Land Use Composition were estimated from Henderson County Planning’s ArcView GIS System based on current County Land Records.

The Town developed, implemented, and will enforce a Stormwater Management Program (SWMP) designed to reduce the discharge of pollutants from its small MS4 to the maximum extent practicable (MEP), to protect water quality, and to satisfy the appropriate water quality requirements of the Clean Water Act. 7.1 PUBLIC EDUCATION AND OUTREACH ON STORM WATER IMPACTS. Minimum Measure (i): A public education and outreach program on the impacts of Stormwater discharges on water bodies to inform citizens of how to reduce pollutants in Stormwater run-off. The public body may satisfy this requirement by developing a local education and outreach program; by participating in a statewide education and outreach program coordinated by the department; or a combination of those approaches. To meet this requirement the Town implemented a public education program to distribute educational materials to the community and conduct outreach activities to educate the public on the impacts of Stormwater discharges on water bodies. Goals: 1. Explore the feasibility of regional approaches to the development and distribution of public educational materials and/or using any statewide education or outreach programs, and develop a public materials distribution plan within two years. Have informational materials available in Town Hall, on the Town’s web-site, and through other mechanisms. 2. Work with local entities including Land-of-Sky Regional Council, the Mud Creek Water Shed Restoration Council, RiverLink, Henderson County Environmental Conservation Organization, and other local agencies and organizations to develop local training sessions and materials for the public. This could include topics such as Phase II Requirements, Low-Impact Design, Watershed Planning and Protection, Erosion and Sediment Control Planning and Design, Hazardous Material Disposal, or Habitat and Stream Restoration. Conduct or support and advertise at least one such training per year. 7.1.1 Discussion. (1) Target Pollutant Sources our Education Program will address and Why: • Sedimentation and Erosion – Laurel Park is a mountainous community. When land is disturbed during any construction process, the erosion rate has the potential to accelerate rapidly. This coupled with natural erosion because of the mountainous terrain makes soil and erosion control a Town priority. • Hazardous Materials – As with any community, the proper disposal of hazardous materials is important. The Town is the headwaters to numerous streams, and the protection of these streams is important to Laurel Park and the surrounding areas. 13 • Fecal Bacteria – Laurel Park has a high number of operating septic systems within the community. Proper maintenance and care of these systems are a priority within the community. (2) Target Audiences that will have storm water impacts: • The general public • Developers • Professional landscapers • Town staff (3) Outreach Program: • The Town worked with the Land-of-Sky Regional Council in establishing a work group, with several other local government entities, to develop outreach strategies and “BMPs”. The regional group developed brochures for the public, newspaper articles, TV ads, and a web page used to educate the public on storm water impacts. The Town includes the brochures developed in welcome packets to new residents and the brochures are available at Town Hall upon request. • The Town continues to work with the Mud Creek Watershed Restoration Council striving to improve and protect water quality throughout the Mud Creek. The Town has one Commissioner on the Council. (4) Evaluation: Laurel Park is a fairly small Town, mainly residential in nature, and it is difficult to evaluate effectiveness of efforts involving outreach. The Town will continue using the mechanisms developed to education the public (web site information, brochures, and news articles). 7.2 PUBLIC INVOLVEMENT AND PARTICIPATION. Minimum measure (ii): A public involvement and participation program consistent with all applicable state and local requirements. To meet this requirement the Town of Laurel Park will: Goals: 1. Continue to seek input and provide updates on Phase II requirements and implementation to the Town Council and the Town Planning Board as part of regularly scheduled public meetings. 2. Use the Planning Board to develop strategies and finalize an implementation plan. 14 3. Explore feasibility of working with other local agencies or adjoining communities to develop public input and informational workshops or other processes. As an example, the Mud Creek Restoration Council. 4. Explore feasibility of initiating a local “Adopt-a-Stream” or “Adopt-a-Creek” program in coordination with RiverLink, Henderson County Environmental Conservation Organization, Scout Troops, or other local entities. 5. Continue to promote and participate in the annual North Carolina “Big Sweep” Event each September urging citizens to do their part to restore the beauty and function of our lakes, streams, rivers, and creeks by volunteering to participate in the North Carolina Big Sweep event. 7.2.1 Discussion: • At the April 20, 2004 Town Council meeting, the Laurel Park Town Council conducted a public hearing to receive comments of the Town’s proposed Stormwater Management Program. • At the January 15, 2008 Town Council meeting, the Laurel Park Town Council conducted a public hearing to receive comments and adopted a Stormwater Management Ordinance. • At the December 20, 2005 Town Council meeting, the Laurel Park Town Council held a public hearing to receive comments of the 2015 Comprehensive Plan and adopted the plan. One of the implementation strategies addressed Stormwater Management. • The Town continues to work with the Mud Creek Watershed Restoration Council striving to improve and protect water quality throughout the Mud Creek. The Town has one Commissioner on the Council. • The Town annually participates in the North Carolina Big Sweep program which is a statewide community effort to retrieve trash from local waterways. • The Friends of Laurel Park sponsors twice a year a litter sweep effort to remove trash from right-of-ways in an effort to eliminate litter from stormwater outlets. 7.2.2 Evaluation: Laurel Park is a fairly small Town, mainly residential in nature, and it is difficult to evaluate the effectiveness of efforts. The Town will continue participating in the programs developed to ensure public involvement and improve Stormwater Management. Currently, the Town experiences minimal complaints on Stormwater Management. 15 7.3 ILLICIT DISCHARGE DETECTION AND ELIMINATION. Minimum Measure (iii): A Program to detect and eliminate illicit discharges within the MS4. The Program shall include a storm sewer system mapping component that at a minimum identifies Stormwater outfalls and the names and location of all waters within the jurisdiction of the public body. To meet this requirement the Town of Laurel Park will develop, implement, and enforce a program to detect and eliminate illicit discharges into the MS4. Goals: 1. Develop a map of the MS4 system and its outfalls relative to available USGS information. Update and maintain as needed. 2. Adopt a local ordinance with regulatory fines to prohibit illicit discharges into the MS4 system or receiving streams. 3. Develop a plan to detect and eliminate illicit discharges as part of the local regulations implemented with the permit. 4. Prevent hazardous materials from reaching area streams through timely and effective emergency management in hazardous spill situations. 5. Regular inspections of existing septic systems and wells by the Henderson County Environmental Health Department will be conducted. 7.3.1 Discussion: • Storm Sewer System Map. A map of Laurel Park’s Storm Sewer System was developed by our consulting engineering firm, William G. Lapsley and Associates. The map shows major outfalls and drainage areas and the names and location of receiving streams relative to USGS mapping information. • Regulatory Mechanism and Enforcement: The Town adopted on January 15, 2008 a Stormwater Management Ordinance using the State model. The ordinance contains enforcement measures that involve notification and potential fines for violations. • Detection and Elimination: Priority for possible illicit discharges is the areas near the receiving streams relative to USGS mapping information. The Town will continue to work closely with the County’s Department of Environmental Health, as needed, to identify and eliminate any contaminants from on-site sewage disposal systems. Procedures for tracing sources of illicit discharges are largely complaint driven and then the complaint is given to the appropriate agency/department for resolution. • Non Stormwater Discharges: The Town’s ordinance states that prohibited substances include but are not limited to: oil, anti-freeze, chemicals, animal waste, paints, garbage, and litter. The ordinance also addresses several allowable discharges, such as, water line flushing, landscape irrigation, rising ground waters, uncontaminated ground water 16 infiltration (as defined at 40 CFR 32.2005(20)), discharges from potable water sources, foundation drains, air conditioning condensation, springs, lawn watering, individual residential car washing, street wash water; and other non-stormwater discharges for which a valid NPDES discharge permit has been approved and issued by the State of North Carolina, and provided that any such discharges to the municipal separate storm sewer system shall be authorized by the Town of Laurel Park. • Outreach: The Town will continue to inform public employees, businesses, and the general public of hazards associated with illegal discharges and improper disposal of waste through informational materials, such as, brochures, web sites, and newsletters. • Staff Training: The Town periodically conducts classes with Public Works personnel highlighting illicit discharge detection (and good housekeeping measures). If staff in another department observes a possible illicit discharge, they would report it to Town Hall. • Evaluation. Over time, we will be able to evaluate overall effectiveness by looking at the number of complaints received. To date, our experience so far suggests that there is not a large problem with illicit discharges, as we have received very few complaints and have not observed any illicit discharges. We will continue education efforts to make sure that the public is aware of an avenue for reporting potential violations. 7.4 CONSTRUCTION SITE STORMWATER RUNOFF CONTROL. Minimum Measure (iv): A program to reduce pollutants in any Stormwater runoff within the MS4 from construction activities resulting in a land disturbance of greater than or equal to one acre. Reduction of storm water discharges from construction activity disturbing less than one acre is included as part of the Town’s overall program. The Town is currently and will continue to meet this requirement by working with Henderson County’s Soil & Erosion Control Division as our locally delegated program for meeting this minimum measure. Their program meets or exceeds the requirements of NCDENR (who we previously delegated prior to the County’s adoption of an ordinance.) The Town refers developers to the County for erosion control permits and works closely with County staff in reporting and resolving possible violations. Also, the Town’s zoning ordinance contains procedures to be followed by builders or property owners when disturbing less than one acre. Goals: 1. Maintain an effective Erosion and Sediment Control Program for construction activities in coordination with the Henderson County Soil and Erosion Control Division for construction activities resulting in land disturbance of greater than one acre. 2. Maintain an effective Erosion and Sediment Control Program for construction activities in coordination with the local zoning ordinance for construction activities resulting in land disturbance of less than one acre (mainly single family residential lots). 17 7.4.1 Discussion: • Regulatory Mechanism: The Town’s subdivision and zoning ordinances both have procedures in place addressing construction activities resulting in land disturbance of more than one acre and in land disturbance less than one acre. • Plan reviews: The Town has procedures for pre-construction review of all site plans. For review of construction activities resulting in land disturbance of more than one acre, a permit is required from the Henderson County Soil and Erosion Office. For review of construction activities resulting in land disturbance of less than one acre, the zoning administrator issues a land disturbing permit. • Enforcement: County staff and the Town zoning administrator accomplishes enforcement. Procedures, such as, stop work orders, fines, bonding (for larger projects) are used for enforcement. • Inspections: Inspections occur on a random basis or on occasion by complaint. • Public Information: The program is included within the overall public education programs. • Evaluation: The program is working extremely well. The Town receives or has initiated approximately two or less complaints a year. The county office has been extremely responsive for any assistance requested and does random inspection on its permits issued. 7.5 POST-CONSTRUCTION STORM WATER MANAGEMENT IN NEW DEVELOPMENT AND REDEVELOPMENT. Minimum Measure (v): A program to address post-construction Stormwater runoff from new development and redevelopment projects that cumulatively disturb greater than or equal to one acre, including projects less than one acre that are part of a larger common plan of development or sale, that discharge into the MS4 or into an interconnected MS4. To meet this requirement the Town will develop, implement, and enforce a program within 12 months from date of permit issuance or 12 months from date of granting of permit by rule status. The program will ensure that controls are in place that would prevent or minimize water quality impacts and will include strategies and structural and non-structural BMPs that are best suited for Laurel Park’s topography and landscape. To achieve this the Town will: Goals: 1. Consider any model ordinance that the State may provide; 2. Use the Town Planning Board to review/draft recommended changes to current ordinances for Town Council review/adoption; and 3. Work with other communities, Land-of-Sky Regional Council, or other agencies to study the feasibility for regional approaches to implementation and enforcement. 18 7.5.1 Discussion: The Town’s program shall require all subject projects to apply for locally issued permit coverage under one of the following Stormwater management options and parameters as set forth in guidance document SWU-268-103102: Low Density Projects. Projects shall be permitted as low density if they meet the following criteria: • No more than two dwelling units per acre or 24 percent built-upon area (BUA) for all residential and non-residential development; • Stormwater run-off from the development shall be transported from the development by vegetated conveyances to the maximum extent practicable; • All BUA shall be at a minimum of 30 feet landward of all perennial and intermittent surface waters. For the purpose of this Rule, a surface water shall be present if the feature is approximately shown on either the most recent version of the soil survey map prepared by the Natural Resources Conservation Service of the United States Department of Agriculture or the most recent version of the 1:24,000 scale (7.5 minute) quadrangle topographic maps prepared by the United States Geological Survey (USGS). An exception to this requirement may be allowed when surface waters are not present in accordance with the provisions of 15A NCAC 2B .0233 (3)(a); and • The permit shall require recorded deed restrictions and protective covenants to ensure that development activities maintain the development consistent with the approved project plans. High Density Projects. Projects exceeding the low density threshold established above shall implement Stormwater control measures that: • Control and treat the difference in Stormwater runoff volume leaving the project site between the pre and post development conditions for the 1 year 24 hour storm. Runoff volume drawdown time shall be a minimum of 24 hours, but not more than 120 hours; • All structural Stormwater treatment systems used to meet the requirements of the program shall be designed to have an 85% average annual removal for Total Suspended Solids; • General Engineering Design Criteria for all projects shall be in accordance with 15A NCAC 2H .1008(c). • All BUA shall be at a minimum of 30 feet landward of all perennial and intermittent surface waters. For the purpose of this Rule, a surface water shall be present if the feature is approximately shown on either the most recent version of the soil survey map prepared by the Natural Resources Conservation Service of the United States Department of Agriculture or the most recent version of the 1:24,000 scale (7.5 minute) quadrangle topographic maps prepared by the United States 19 Geological Survey (USGS). An exception to this requirement may be allowed when surface waters are not present in accordance with the provisions of 15A NCAC 2B .0233 (3)(a); and • The permit shall require recorded deed restrictions and protective covenants to ensure that development activities maintain the development consistent with the approved project plans. Operation and Maintenance: The Town’s program shall include an operation and maintenance component that ensures the adequate long-term operation of the structural BMPs required by the program. The program shall require owners of permitted BMPs to submit annual maintenance and inspection reports conducted and certified by a qualified professional. NOTE: Since implementation no development of this nature has occurred. Control of Fecal Coliform: The Town works closely with the Henderson County Environmental Health Department to ensure the proper operation and maintenance of on- site, private wastewater treatment systems, septic, and private well systems. Programs Draining into SA Waters: N/A Programs draining into trout (Tr) waters: A portion of community is a source of the North Fork Willow Creek, classified as C Tr waters. The Town shall require that, if necessary, selected BMPs that impact this stream do not result in a sustained increase in the receiving water temperature. Programs for Draining into Nutrient Sensitive Waters: N/A Watershed Planning: Local Water Supply Watershed Program: The Town of Laurel Park adopted on January 30, 1997, and amended, on December 17, 2002, the provisions of the Watershed Protection Act (NCGS 143-214.5). This ordinance has strict limits on density and built- upon limits with the watershed and includes stream buffer area requirements (see 3.1a). Natural Resource Protection: Area addressed in above discussions. Open Space Protection: The Town Zoning Ordinance requires 20% of gross lot area to be reserved for landscaping for any commercial development. The Town enforces the stream buffer requirements contained with the Local Water Supply Watershed Program. 20 Street Design: The Town follows the DOT Minimum Construction standards in reviewing any new roads associated with new development. Evaluation: Being a small mainly residential community, the Town has not dealt with any multi-unit development in the past several years, evaluation approaches dealing with multi-unit development will be followed in the event of this type activity should occur. 7.6 POLLUTION PREVENTION/GOOD HOUSEKEEPING FOR MUNICIPAL OPERATIONS. Minimum Measure (vi): A pollution prevention/good housekeeping program for municipal operations that addresses operation and maintenance, including a training component, to prevent or reduce pollutant runoff from those operations. To meet this requirement the Town will develop and implement an operation and maintenance program that includes a training component and has the ultimate goal of preventing or reducing pollutant runoff from municipal operations. To address these concerns, the Town: Goals: 1. Work with the NC Division of Pollution Prevention and Waste Reduction Partners of Land-of- Sky Regional Council to conduct a Good Housekeeping and Pollution Prevention Assessment of the Public Works facility and implement recommendations from the assessment. 2. Continue current maintenance policies and practices of good housekeeping and pollution prevention. 3. Use available training materials from EPA, the State, or other organizations as part of employee training annually. 7.6.1 Discussion: • Affected Operations: The principle municipal operations of the Town of Laurel Park relevant to this permit program are those of automotive/equipment maintenance, vehicle/equipment storage, and materials storage that all occur in the Public Works Facility, 500 Toms Drive, Laurel Park, North Carolina. • Training: The Town will continue to seek training for maintenance and public works personnel in pollution prevention and good housekeeping measures. Selected personnel attended a training session prepared by the Land of Sky Regional Council. The Town will continue periodic on-site training of Public Works Personnel. 21 • Maintenance and Inspections: The Town maintenance staff operates from the maintenance facility daily practicing good housekeeping and pollution prevention for the site. • Vehicular Operations: The Town of Laurel Park’s fleet includes 15 vehicles: Police vehicles: 1 Ford Escape, 3 Ford Explorers, 4 Chevrolet Impalas. Public Works: 5 light pick up trucks, 2 heavy duty Dump trucks. Light vehicle maintenance (oil changes, tire rotation, etc.) for vehicles is accomplished at the Public Works Facility. Used oil is collected for recycling and stored in appropriate containers until removal. Automotive repair and significant maintenance for Town vehicles is done by local private mechanic services. The Town operates a refueling point for vehicles. The 1000-gallon tank is built of double wall construction to prevent leakage and inspected as required. Salt and sand for snow removal are contained in a covered storage area at the Public Works Facility. Other materials are also stored within the Public Works area facility. Hazardous materials are stored in a locked chemical cabinet. • Waste Disposal: The Town does not own or operate a waste transfer station. The Town contracts weekly for residential collection of garbage and recyclables. • Other evaluations: The Town has recently worked with Henderson County in updating the countywide Hazard Mitigation Plan. One objective for the Town is to develop a flood damage prevention ordinance. Although less than 5% of the community is in a mapped flood zone, the Town adopted a flood prevention ordinance effective August 19, 2008 and residents who desire may now get flood insurance. As a small Town we have limited municipal operations and vehicle maintenance. The Town does not own/operate ambulance services, EMT services, transportation or transit services, a wastewater treatment plant, a landfill, and a recyclables processing center, an airport, or marina. The Town contracts for fire services with the Valley Hill Fire and Rescue Department. • Evaluation: The Town will continue to monitor the BMP goals for effectiveness. The Town has not experienced any problems associated with good housekeeping for municipal operations.
