ENVIRONMENTAL CONSERVATION STANDARDS
This Chapter sets forth standards for environmental protection and conservation in the Town of Waynesville's land use jurisdiction concerning a variety of different environmental issues. The Town of Waynesville possesses an abundance of unique natural assets. The standards set forth in this section address the enhancement and preservation of these important features. (Article VIII summary)
Land subject to flood hazard, improper drainage, erosion, landslides or that is for topographical or other reasons unsuitable for development as determined by the Town of Waynesville, shall not be platted or developed for residential use nor for any other uses that will continue or increase the danger to health, safety, or property unless the hazards are corrected or mitigated.
12.2.1 Landfill Development.
Areas that have been used for the disposal of solid waste shall not be subdivided into commercial or residential building sites. This includes areas that have been used for the disposal of trash, demolition waste, construction debris, stumps, and other waste materials.
12.3.1 Statutory Authorization, Findings of Fact, Purpose and Objectives.
A.
Statutory Authorization: The Legislature of the State of North Carolina has in Part 6, Article 21 of Chapter 143; Articles 7, 9, 11, and 13 of Chapter 160D; and Article 8 of Chapter 160A; and Article 7, 9, and 11 of Chapter 160D of the North Carolina General Statutes, delegated to local governmental units the responsibility to adopt regulations designed to promote the public health, safety, and general welfare.
Therefore, the Town Council of the Town of Waynesville, North Carolina, does ordain as follows:
B.
Findings of Fact:
1.
The flood prone areas within the jurisdiction of the Town of Waynesville are subject to periodic inundation which results in loss of life, property, health and safety hazards, disruption of commerce and governmental services, extraordinary public expenditures of flood protection and relief, and impairment of the tax base, all of which adversely affect the public health, safety, and general welfare.
2.
These flood losses are caused by the cumulative effect of obstructions in floodplains causing increases in flood heights and velocities and by the occupancy in flood prone areas of uses vulnerable to floods or other hazards.
C.
Statement of Purpose: It is the purpose of this ordinance to promote public health, safety, and general welfare and to minimize public and private losses due to flood conditions within flood prone areas by provisions designed to:
1.
Restrict or prohibit uses that are dangerous to health, safety, and property due to water or erosion hazards or that result in damaging increases in erosion, flood heights or velocities;
2.
Require that uses vulnerable to floods, including facilities that serve such uses, be protected against flood damage at the time of initial construction;
3.
Control the alteration of natural floodplains, stream channels, and natural protective barriers, which are involved in the accommodation of floodwaters;
4.
Control filling, grading, dredging, and all other development that may increase erosion or flood damage; and
5.
Prevent or regulate the construction of flood barriers that will unnaturally divert flood waters or which may increase flood hazards to other lands.
D.
Objectives: The objectives of this ordinance are to:
1.
Protect human life, safety, and health;
2.
Minimize expenditure of public money for costly flood control projects;
3.
Minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the expense of the general public;
4.
Minimize prolonged business losses and interruptions;
5.
Minimize damage to public facilities and utilities (i.e., water and gas mains, electric, telephone, cable and sewer lines, streets, and bridges) that are located in flood prone areas;
6.
Minimize damage to private and public property due to flooding;
7.
Make flood insurance available to the community through the National Flood Insurance Program;
8.
Maintain the natural and beneficial functions of floodplains;
9.
Help maintain a stable tax base by providing for the sound use and development of flood prone areas; and
10.
Ensure that potential buyers are aware that property is in a Special Flood Hazard Area.

12.4.1 Purpose.
This section is adopted in accordance with the North Carolina Sedimentation Pollution Control Act of 1973 as amended for the purpose of regulating certain land-disturbing activity to control accelerated erosion and sedimentation in order to prevent the pollution of water and other damages to watercourses and public and private property by sedimentation.
12.4.2 Applicability.
This section shall not apply to the following land-disturbing activities:
A.
Activities, including the breeding and grazing of livestock, undertaken on agricultural land for the production of plants and animals useful to man.
B.
Activities undertaken on forestland for the production and harvesting of timber and timber products and conducted in accordance with best management practices set out in Forest Practice Guidelines Related to Water Quality, as adopted by the North Carolina Department of Environment, Health and Natural Resources. If not conducted in accordance with these guidelines, the provisions of this section shall apply to such activity and any related land disturbing activity on the tract.

D.
For the duration of an emergency, activities essential to protect human life.
E.
Land disturbing activities conducted by the State of North Carolina; by the United States; by persons having the power of eminent domain; by local governments; or which are licensed or bonded, in whole or in part, by the State of North Carolina or the United States; all of which are under the exclusive regulatory jurisdiction of the State of North Carolina.
F.
Those done for the purposes of fighting fires.
G.
The stock-piling of fill dirt, raw or processed sand, stone or gravel in material processing plants and storage yards, provided that sediment control measures have been utilized to protect against off-site damage.
H.
Individual gravesites.
I.
Lawns, gardens and similar horticultural activities.
J.
Activities undertaken on agricultural lands which do not exceed one thousand (1,000) square feet of land disturbance. In determining land disturbance, lands under diverse ownership being developed as a unit shall be aggregated.
12.4.3 General Requirements.
A.
Plan Required: No person shall initiate any land-disturbing activity exceeding one thousand (1,000) square feet of land, without first having an approved sedimentation and erosion control plan as set forth in Section 154.088.
B.
Basic Control Objectives: The basic control objectives of this section and approved sedimentation and erosion control plans are set forth below.
1.
On-site areas which are subject to severe erosion, and off-site areas which are especially vulnerable to damage from erosion and/or sedimentation, are to be identified and receive special attention.
2.
All land-disturbing activities are to be planned and conducted to limit exposure to the shortest feasible time.
3.
All land-disturbing activities are to be planned and conducted to limit the size of the area to be exposed at any one time.
4.
Surface water runoff originating upgrade of exposed areas should be controlled to reduce erosion and sediment loss during the period of exposure.
5.
All land-disturbing activities shall be planned and conducted so as to prevent off-site sedimentation damage.
6.
When the increase in the velocity of stormwater runoff resulting from a land-disturbing activity is sufficient to cause accelerated erosion of the receiving watercourse, plans must include measures to control the velocity to the point of discharge so as to minimize accelerated erosion of the site and increased sedimentation of the stream.
12.4.4 Mandatory Standards for Land-Disturbing Activity.
No land-disturbing activity subject to the control of this section shall be undertaken except in accordance with the following mandatory standards:
A.
Buffer Zone around Water Bodies.
1.
No land disturbing activity during periods of construction or improvement to land shall be permitted in proximity to a lake or natural watercourse unless a buffer zone is provided along the margin of the watercourse of sufficient width to confine visible siltation within the twenty-five (25%) percent of the buffer zone nearest the land-disturbing activity.
2.
Waters that have been classified as trout waters by the state environmental management commission shall have an undisturbed buffer zone twenty-five (25) feet wide or of sufficient width to confine visible siltation within the twenty-five (25) percent of the buffer zone nearest the land-disturbing activity, whichever is greater. Provided, however, the town may approve plans which include land-disturbing activity along trout waters when the duration of the disturbance would be temporary and the extent of the disturbance would be minimal. This subsection shall not apply to land-disturbing activity in connection with the construction of facilities to be located on, over, or under a lake or natural watercourse.
3.
Unless otherwise provided, the width of a buffer zone is measured from the edge of the water to the nearest edge of the disturbed area, with the twenty-five (25) percent of the strip nearer the land-disturbing activity containing natural or artificial means of confining visible siltation.
4.
The twenty-five (25) foot minimum width for an undisturbed buffer zoned adjacent to designated trout waters shall be measured horizontally form the top of the bank.
5.
When a temporary and minimal disturbance is permitted as an exception, land-disturbing activities in the buffer zone adjacent to designated trout waters shall be limited to a maximum of ten (10) percent of the total length of the buffer zone within the tract to be disturbed such that there is not more than one hundred (100) linear feet of disturbance in each one thousand (1,000) linear feet of buffer zone. Larger areas may be disturbed with written approval of the Administrator.
6.
No land-disturbing activity shall be undertaken within a buffer zone adjacent to designated trout waters that will cause adverse temperature fluctuations in these waters, as set forth in 15 NCAC 2B. 0211 "Fresh Surface Water Classification and Standards (available at the North Carolina Division of Environmental Management).
B.
Graded Slopes and Fills.
1.
The angle for graded slopes and fills shall be no greater than the angle which can be retained by vegetative cover or other adequate erosion control devices or structures, and which can be demonstrated to be stable. Stable is defined as the condition where soil remains in its original configuration, with or without mechanical constraints.
2.
In any event, slopes left exposed shall, within thirty (30) working days of completion of any phase of grading, be planted or otherwise provided with ground cover, devices or structures sufficient to restrain erosion.
3.
Fill slopes greater than two (2) feet horizontal run to one (1) foot vertical rise (2:1) and higher than five (5) feet above adjacent grade, and cut slopes steeper than one and three-quarters (1.75) feet horizontal run to one (1) foot vertical rise and higher than five (5) feet above adjacent grade, shall be designed by a registered professional and upon completion shall be certified to be stable by a registered professional engineer or landscape architect.
4.
All fill slopes shall be compacted full depth to not less than ninety-five (95) percent maximum density (Standard Proctor), shall be placed on a surface cleared of growth and debris, and be properly benched and drained. Such certification shall be required prior to issuance of any certificate of compliance for the site, and shall in any case be submitted within thirty (30) days of the slope reaching final grade.
5.
Terracing or slope breaks should be used on steep slopes to reduce the length of cut and fill slopes to prevent erosion and formation of gullies. Benches should be five (5) feet wide, rounded at the edges, and spaced according to the following table:
6.
The use of gunite or similar materials is not allowed as a method for slope stabilization.
C.
Groundcover.
1.
Whenever any land-disturbing activity is undertaken, the person conducting the land-disturbing activity shall install such sedimentation and erosion control devices and practices as are sufficient to retain the sediment generated by the land-disturbing activity within the boundaries of the tract during construction upon and development of the tract, and shall plant or otherwise provide a permanent ground cover sufficient to restrain erosion after the completion of construction or development.
2.
Except as provided elsewhere in this section provisions for a ground cover sufficient to restrain erosion must be accomplished within thirty (30) calendar days following completion of construction or development, whichever period is shorter.
D.
Grading of Steep Slopes.
1.
Grading on residentially zoned property with a slope in excess of fifteen (15) percent shall be limited to disturbing not more than five (5) acres at a time.
2.
Any one disturbed area must be brought into final compliance with the requirements of the standards set forth in this section.
3.

If the violator does not pay for the clean-up cost, revoked permits shall not be reissued and a lien shall be place on the violator's property until the cost is recouped by the town.
It is hereby determined that:
• This section shall be officially known as "the stormwater ordinance." It is referred to herein as "this section."
• 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 which 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.
Therefore, the Town of Waynesville has established this set of water quality and quantity regulations to meet the requirements of state and federal law regarding control of stormwater runoff and discharge.
12.5.1 Purpose.
The purpose of this section 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, as well as illicit discharges into the Town of Waynesville's municipal stormwater systems. 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. These requirements establish stormwater management requirements and controls to prevent surface water quality degradation to the extent practicable in the streams and lakes within the Town Limits and Extraterritorial Jurisdiction of Waynesville. This Section seeks to meet this purpose by fulfilling the following objectives:
• Minimize increases in stormwater runoff from new development or redevelopment to the maximum extent practicable for the applicable design storm in order to reduce flooding, siltation, streambank erosion, increases in stream temperature, and to maintain the integrity of stream channels and aquatic habitats.
• Minimize increases in non-point and point source pollution caused by stormwater runoff from development or redevelopment that would otherwise degrade local water quality. Minimize the total volume of surface water runoff that flows from any specific site during and following development in order to replicate pre development hydrology to the maximum extent practicable through the use of structural and nonstructural stormwater management Best Management Practices (BMPs).
• Establish minimum post development stormwater management standards and design criteria for the regulation and control of stormwater runoff quantity and quality.
• Establish design and review criteria for the construction, function, and use of structural stormwater BMPs (also called stormwater control measures, or SCMs) that may be used to meet the minimum post-development stormwater management standards.
• Ensure that structural and nonstructural stormwater BMPs are properly maintained and pose no threat to public health or safety.
• 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.
• Control illicit discharges into the municipal separate stormwater system.

A.
Reference to Design Manual: The Town of Waynesville shall use the policy, criteria, and information, including technical specifications and standards, in the North Carolina Department of Environmental Quality (NC DEQ) Stormwater Design Manual as the basis for decisions about stormwater plans and about the design, implementation, and performance of structural and non-structural stormwater control measures.
The Design Manual includes a list of acceptable stormwater treatment practices, including specific design criteria for each stormwater practice. Stormwater treatment practices that are designed, constructed, and maintained in accordance with these design and sizing criteria will be presumed to meet the minimum water quality performance standards of the Phase II and other applicable stormwater laws.
B.
Right to Consult: Stormwater management practices that are designed, constructed, or maintained in accordance with the Stormwater Design Manual are presumed to comply with these requirements. However, the Stormwater Administrator shall have the right to consult duly qualified professionals to impose any conditions or require any modifications deemed necessary to meet the purpose, intent, and requirements of this section.
C.
Relationship of Design Manual to Other Laws and Regulations: If the specifications or guidelines of the Design Manual are more restrictive or apply a higher standard than other laws or regulations, that fact shall not prevent application of the specifications or guidelines in the Design Manual.
D.
Changes to Standards and Specifications: If the standards, specifications, guidelines, policies, criteria, or other information in the Design Manual are amended subsequent to the submittal of an application for approval pursuant to this ordinance but prior to approval, then Section 15.16.1-Permit Choice will apply.
12.5.7 Standards.
A.
General Requirements:
1.
A Stormwater Management System Concept Plan is required for all development and redevelopment projects to which this section applies. This plan shall be prepared by a licensed professional engineer or landscape architect and meet the design specifications of the Town of Waynesville in addition to those standards set forth in this section. See Section 15.7.3 for the specific application process.
2.
The use of natural vegetation and creative landscaping in establishing stormwater control measures is required if applicable. A developer must incorporate the use of natural topography and land cover such as wetlands, ponds, natural swales as they exist prior to development to the degree that they can accommodate the additional flow of water.
3.
Developers are required to use the aforementioned natural measures as well as other BMPs (pervious pavement, discontinuous imperviousness, etc.) in developing property in the town's jurisdiction for the purpose of cleansing and diffusing surface water flow.
4.
Developments shall be designed and constructed with a positive drainage flow away from buildings towards approved stormwater management facilities.
5.
No utilities or habitable structures may be located within any impoundment area of any stormwater management facility. Structures may not be located over a storm drainage line.
6.
All stormwater management facilities will be considered permanent.
7.
[Reserved.]
8.
No stormwater structure, or part thereof, shall project into the property setbacks as established for each zoning district in Section 2.4 Dimensional Standards. If there is no setback or setback is less than 10 feet, then use a minimum distance of 10 feet from the perimeter lot line to a stormwater structure or any part thereof.
9.
Fencing: All sections of stormwater structures shall be surrounded with a permanent, continuous fence or vegetation barrier at the top of the embankment with no opening wider than two (2) inches if a stormwater structure contains:
• A proposed retaining wall higher than 4 feet, and/or
• A 3:1 slope, and/or
• A slope height from the toe of the SCM to the crest is greater than 5 feet.
Any stormwater structure with a continuous fence around the entire perimeter shall provide ingress and egress for SCM/pond maintenance but restricted by lockable gates of adequate size to allow for the easy passage of necessary maintenance equipment. Fences shall be shown on all as-built plans.
10.
Signage: Any SCM that is designed as a pond must have warning signs posted for public visibility and at any major approach to the pond, identifying the area as a stormwater management site to raise public awareness of potential hazards of the site (i.e., no swimming, boating, skating, unsafe to enter, etc.).
11.
Conversion to Stormwater Management Structure: After permanent stabilization of all disturbed contributory drainage areas and flushing of the storm drains, temporary sediment basins, if initially built and certified to meet permanent standards, may be converted to permanent stormwater management structures. To convert the basin from temporary to permanent use, the outlet structure must be modified in accordance with approved stormwater management design plans and inspected for watertight connections. Sediment and other debris should be removed to a contained spoil area. Regrading of the basin may be necessary to achieve the final design grades and to provide an adequate topsoil layer to promote final stabilization. Final elevations and a complete description of any modifications to the riser structure's geometry should be shown on the approved plans.
B.
Water Quality Design Requirements:
1.
All Low Density projects and High Density projects must have the built-upon area at a minimum of thirty (30) feet landward of all perennial and intermittent surface waters. This distance shall be measured horizontally from the edge of water. A perennial or intermittent surface water shall be deemed 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 (USDA) or the most recent version of the 1:24,000 scale (7.5 minute) quadrangle topographic maps prepared by the United States Geologic Survey (USGS). An exception to this requirement may be allowed when site-specific determination is made using NC Division of Water Quality-approved methodology.
2.
In addition to the standards for stormwater management set out in this section, development and redevelopment that drains in whole or part to class TR waters shall design and implement stormwater best management practices that do not result in a sustained increase in the receiving water temperature, while still meeting the other requirements of this section.
3.
The stormwater approval issued shall require recorded deed restrictions and protective covenants to ensure that future development activities maintain the stormwater management measures consistent with the approved project plans.
4.
All Low Density Project sites must employ LID practices to analyze the infiltration capacity and natural drainages of the site and develop a system of controls which mimic the existing natural hydrology and which cumulatively capture and treat the runoff from the 1-year 1-hour storm event. Wherever LID practices are not achievable, or have not been demonstrated, the stormwater management measures shall be designed to control the stormwater runoff according to the requirements of this section.
5.
All High Density projects, for both LID and conventional design approaches, shall include stormwater management measures designed to control the stormwater runoff according to the requirements of this section.

The drawdown time shall be a minimum of 48-hours and a maximum of 120-hours.
b.
The minimum draw down orifice size shall be 2-inches or equivalent.
c.
The post development peak flow rates discharged shall not exceed the pre development 1-year 24 hour peak discharge rates.
5.
No one BMP shall receive runoff from an area greater than three (3) acres. However, the total drainage area from BMPs used in series (i.e., integrated) can exceed this three (3) acre maximum.
6.
Water quality BMPs may encroach into a required buffer as long as the encroachment does not disturb the majority of existing vegetation. Minor understory may be disturbed in order to accommodate water quality structures. Trees and shrubs shall be placed to maximize screening where the encroachment takes place.
7.
General engineering for all projects shall be in accordance with 15A NCAC 2H.1008(c).
8.
All stormwater control measures and stormwater treatment practices required under this ordinance shall be evaluated by the Stormwater Administrator according to the policies, criteria, and information, including technical specifications, standards, and the specific design criteria for each stormwater practice, in the Design Manual. The Stormwater Administrator shall determine whether proposed SCMs/BMPs will be adequate to meet the requirements of this ordinance.
D.
Water Quantity Design Requirements:
1.
For any development to which this section applies, stormwater management facilities, structures, devices and methods shall be designed and built with sufficient capacity to accommodate surface runoff caused by the development in excess of that runoff which would occur from the site if left in its pre development condition.
2.
The calculated difference in the peak runoff rate from the post development peak flow rates, less the pre-development shall determine the size of detention structures.
3.
The storage shall be sufficient to store all excess surface runoff up to the 10-year 24-hour storm event.
4.
The post development peak flow rates discharged from any development that this section applies, shall not exceed the pre development peak discharge rates for the 2-year, 24-hour storm event and the 25-year, 24-hour storm event.

9.
The impoundment of stormwater runoff may be incorporated in the design of stormwater conveyance structures, engineered stormwater BMPs, and ponds. These structures may be located on or off site.
10.
In all instances engineered stormwater management facilities and devices shall be designed to complement a development and the surrounding community. If ponds are used, such areas shall be landscaped as amenities or hidden from view.
E.
Stormwater Conveyance Systems Design Requirements:
1.
Stormwater collection systems (drainage parallel to road, including ditches, swales and pipes) shall be designed to pass the peak flows from the 2-year, 24-hour storm event. The minimum allowable pipe size is 15-inches.
2.
Cross drainage systems that do not convey intermittent or perennial streams shall be designed to pass the peak flow rates from the 10-year, 24-hour storm event.
3.
Cross drainage systems conveying intermittent or perennial streams, shall be designed pass peak flow rates for the 50-year, 24-hour storm event. These structures shall consist of bottomless single span structures.
4.
Inlet capacity and spread calculations must be provided. Roadway inlet locations, capacities, gutter spread, and storm drain pipe system shall be analyzed and designed using a 10-year discharge with a minimum time of concentration of 10 minutes. An intensity of 4 inches/hour should be used for calculating spread and determination of appropriate locations for inlet placement to collect roadway pavement runoff.
5.
It is desirable that inlets be designed for 100% interception of runoff, but minor bypass discharge to a downstream inlet is acceptable if it is accounted for in design computations.
6.
On grades, the curb opening can be ignored in determining inlet capacity. The grate efficiency may be assumed to equal that of a parallel bar grate.
7.
Inlet capacity at sags should allow for debris blockage by providing twice the required computed opening (i.e., assume 50% blockage).
8.
Inlet spacing shall be sufficient to limit spread as required for safe vehicle maneuverability. Allowable spread into the travel lane during temporary conditions (detours, phased construction, etc.) should be evaluated based on factors, such as traffic volume, road classification, posted speed limit, and lane width. For curb and gutter sections (with no side parking or bike lanes), the width of the gutter pan is considered the "shoulder."
9.
If the design speed is less than or equal 45 mph, then the allowable spread is up to half the travel lane. If the design speed is greater than 45 mph, the allowable spread shall maintain in the shoulder.
10.
All storm drain grates shall be perpendicular to the travel way.
F.
Uniform Watershed Analysis:
1.
Uniform Watershed Analysis is required for all developments. Calculations must be developed to show the development's impact on the greater watershed.
2.
The requirements, or portions thereof, for detention may be waived by the Stormwater Administrator if it can be shown by detailed engineering calculations and analysis which are acceptable to the Administrator that one of the following exists:
a.
The installation of stormwater management facilities would have insignificant effects on reducing downstream flood peak flow rates and water surface elevations.
b.
Stormwater management facilities are not needed to protect downstream developments and the downstream drainage system has sufficient capacity to receive any increase in runoff for the design storm.
c.
It is not necessary to install stormwater management facilities to control post development peak discharge rates at the exit to a proposed development and installing such facilities would increase flood peak flow rates and or water surface elevations at some downstream locations.
d.
The Administrator determines that stormwater management facilities are not needed to control post development peak discharge rates and installing such facilities would not be in the best interest of the Town.
3.
The requirements, or portions thereof, of this section may not be waived if the Administrator determines that not controlling peak flow rates would increase known flooding problems, or exceed the capacity of the downstream drainage system.
4.
A waiver shall only be granted after a written request is submitted by the applicant containing descriptions, drawings, and any other information that is necessary to evaluate the proposed development or redevelopment. A separate written waiver request shall be required if there are subsequent additions, extensions, or modifications which would alter the approved stormwater runoff characteristics of the development or redevelopment receiving a waiver.
5.
Discharge velocities shall be reduced to provide a non-erosive velocity flow from a structure, channel, or other control measure or the velocity of the 2-year 24-hour design storm runoff in the receiving waterway prior to the development, whichever is greater.
6.
For all stormwater management facilities, a hydrologic/hydraulic study shall be conducted showing how the drainage system will function with and without the proposed facilities. For such studies the existing and developed land use conditions shall be used. Existing land use data shall be taken from the most recent aerial photograph and field checked and updated.
7.
For the design of the facility outlet structure, use developed land use conditions for the area within the proposed development and existing land use conditions for upstream areas draining to the facility.
8.
For any analysis of flood flows downstream from the proposed development, use existing land use conditions for all downstream areas.
12.5.8 Exceptions to the 30-Foot Setback.
Exceptions from the 30-foot landward location of built-upon area requirement of all perennial and intermittent surface waters as well as the deed restrictions and protective covenants requirements shall be granted by the Administrator in any of the following instances:
A.
When there is a lack of practical alternatives for a road crossing, railroad crossing, bridge, airport facility, or utility crossing (including water, sewer, or gas construction and maintenance corridors) as long as it is located, designed, constructed, and maintained to minimize disturbance, provide maximum nutrient removal, protect against erosion and sedimentation, have the least adverse effects on aquatic life and habitat, and protect water quality to the maximum extent practicable through the use of BMPs.
B.
When there is a lack of practical alternatives for a stormwater treatment measures. A lack of practical alternatives may be shown by demonstrating that, considering the potential for a reduction in size, configuration, or density of the proposed activity and all alternative designs, the basic project purpose cannot be practically accomplished in a manner which would avoid or result in less adverse impact to surface waters.
1.
These measures shall be located, designed, constructed, and maintained to minimize disturbance, provide maximum nutrient removal, protect against erosion and sedimentation, have the least adverse effects on aquatic life and habitat, and protect water quality to the maximum extent practicable.
2.
The implementation of the alternative stormwater treatment measures shall not disturb existing vegetation.
3.
Minor understory trees may be disturbed in order to accommodate these measures. Trees and shrubs shall be placed to maximize screening where the encroachment takes place.

A.
Trout Waters: In addition to the standards for handling stormwater set out in the Design Manual, development and redevelopment that drains in whole or part to class TR waters shall design and implement the best stormwater practices that do not result in a sustained increase in receiving water temperature, while still meeting the other requirements of this ordinance.
B.
Pet Waste: Pet waste can pollute rivers, streams, and lakes. Stormwater runoff carries pet waste into drainage ditches and storm drains where it is then dumped, untreated, into the nearest waterway. Dog waste contains bacteria, viruses, and parasites that can harm humans and affect water quality. Once in a waterway, pet waste can travel long distances and pollute a large area. Therefore:
• It shall be unlawful for the owner or custodian of any dog to take it off the owner's own property limits without the means to properly remove and dispose of the dog's feces from any public or private property.
• It is the responsibility of a dog's owner or custodian to clean up the dog's feces from any public or private property outside of the dog's owner's own property limits. Such property includes, but is not limited to, parks, rights-of-way, paths, and public access areas.
• "Means to properly remove and dispose of feces" shall consist of having on or near ;hg;one's person a device such as a plastic bag, or other suitable plastic or paper container, that can be used to clean up and contain dog waste until it can be disposed of in an appropriate container.
• This provision shall not apply to handicapped persons assisted by trained guide or assistance dogs.

12.6.1 Purpose.
The purpose of this section is to regulate development in steep slope areas in order to preserve the Town of Waynesville's unique character, conserve the public health, safety and general welfare and to promote environmentally sound design and planning in accordance with the following objectives:
• To protect life and property from all potentially hazardous conditions particular to steep slopes, e.g., rock falls, flash flooding, debris flows, mud slides and increased wildfire hazard.
• To preserve and enhance the scenic and environmental resources of the landscape by encouraging the maximum retention of prominent natural topographic features, i.e., drainage swales, streams, slopes, ridgelines, rock outcroppings, vistas, natural plant formations, and trees.
• To encourage innovative site and architectural design and planning in order for the development to adapt to the natural terrain and be harmonious with the character of the area.
• To minimize grading and cut and fill operations inconsistent with the retention of the natural character of the hillside.
• To preserve where possible, natural streams, ponds and associated riparian vegetation.
• To require the retention of trees and other vegetation to stabilize steep hillsides, retain moisture, prevent erosion and enhance the natural scenic beauty.
• To encourage the retention of trees and other vegetation throughout the site instead of just the periphery of the development.
• To encourage minimal grading which relates to the natural contour of the land, thus rounding off sharp angles at the top and bottom of cut and fill slopes in a natural manner.
• To provide land use densities to promote the best possible development of hillside areas in order to retain significant natural features and to preserve slope stability.
• To encourage road design that follows the natural topography wherever possible in order to minimize grading.
• To preserve predominant views from and of the hillside areas in order to retain the sense of identity and imagery that the hills and mountains now impart to the Town of Waynesville.
12.6.2 Applicability.
A.
For the purposes of this section, a Steep Slope Area is defined as any lot, parcel, tract or portion thereof, that has a natural elevation of 2,900 feet above mean sea level or higher, with a natural average slope of 25% or greater as determined using the following formula:
S = 0.0023 × I × L
A
Where:
S = Average natural slope of parcel in percent
I = Contour interval of map in feet
L = Total length of contour lines within the parcel in feet
A = Area in acres of the parcel
0.0023 = Constant which converts square feet into acres
B.
In the case of conflict between the average natural slope determination of a lot using different methods of calculation the following methods in shall prevail in the following order: 1) use of the above formula based on field survey data, 2) use of the above formula based on the best available topographic data in the Haywood County Geographic Information system, 3) use of a Town approved geographic information system based slope calculation tool.
C.
Application to properties with an average natural slope of 25% or greater split by the 2,900-foot contour line.
1.
If any portion of the lot above 2,900 feet is placed in a permanent conservation easement or otherwise reserved in perpetuity, the residential density from this portion of the property may be transferred to the remainder of the property below 2,900 feet or to adjacent properties in the same ownership below 2,900 feet at the same ratio as that of the underlying zoning district.
2.
The area above 2,900 feet may be developed as provided for in Table 12.6.4, and the remainder of the property below 2,900 feet or with an average slope below 25% may be developed as permitted in the underlying zoning district.
D.
Reservation of steep slope areas to reduce average slope. Areas placed in a permanent conservation easement, dedicated to the public for open space, protected as open space by restrictive covenants or otherwise permanently protected in a natural state with a prohibition on vegetation removal and land disturbing activity may be excluded from the calculation of the average slope for the property or properties which include the area, provided that the minimum size of each such reserved area shall equal the minimum lot size for the underlying zoning district.
12.6.3 General Steep Slope Area Development Standards.
A.
No land disturbing activity shall take place until full development approval has been received.
B.
Land disturbing activity shall be limited to designated building envelopes and approved road and driveway corridors as shown on approved site plans.
C.
Diversion or channelization of perennial streams shall not be permitted unless without such diversion or channelization a tract existing at the time of adoption of this amendment is rendered unusable for any of the principal uses allowed within the zoning district.
D.
The riparian stream buffers shall be left intact, which means that removal of trees, or other vegetation, or disturbance of soils within this buffer is prohibited, except for necessary road crossings. The buffers shall be a minimum of 30' from the edge of the stream or 25 feet from the top of bank, whichever is greater.
E.
Perennial streams shall not be placed in culverts except to the minimum extent possible for necessary road crossings.
F.
Developers shall make reasonable efforts to preserve and protect existing natural features of the slope, such as trees and other plan material, and rock outcroppings which may help to stabilize the slope.
G.
The maximum area of disturbance per phase shall not exceed 5 acres.
H.
Cut and fill slopes shall comply with the standards of Section 12.4.
I.
Stormwater management shall comply with the standards of Section 12.5.

Therefore, the Town Council of the Town of Waynesville, North Carolina, does ordain as follows:
B.
Findings of Fact:
1.
The flood prone areas within the jurisdiction of the Town of Waynesville are subject to periodic inundation which results in loss of life, property, health and safety hazards, disruption of commerce and governmental services, extraordinary public expenditures of flood protection and relief, and impairment of the tax base, all of which adversely affect the public health, safety, and general welfare.
2.
These flood losses are caused by the cumulative effect of obstructions in floodplains causing increases in flood heights and velocities and by the occupancy in flood prone areas of uses vulnerable to floods or other hazards.
C.
Statement of Purpose: It is the purpose of this ordinance to promote public health, safety, and general welfare and to minimize public and private losses due to flood conditions within flood prone areas by provisions designed to:
1.
Restrict or prohibit uses that are dangerous to health, safety, and property due to water or erosion hazards or that result in damaging increases in erosion, flood heights or velocities;
2.
Require that uses vulnerable to floods, including facilities that serve such uses, be protected against flood damage at the time of initial construction;
3.
Control the alteration of natural floodplains, stream channels, and natural protective barriers, which are involved in the accommodation of floodwaters;
4.
Control filling, grading, dredging, and all other development that may increase erosion or flood damage; and
5.
Prevent or regulate the construction of flood barriers that will unnaturally divert flood waters or which may increase flood hazards to other lands.
D.
Objectives: The objectives of this ordinance are to:
1.
Protect human life, safety, and health;
2.
Minimize expenditure of public money for costly flood control projects;
3.
Minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the expense of the general public;
4.
Minimize prolonged business losses and interruptions;
5.
Minimize damage to public facilities and utilities (i.e., water and gas mains, electric, telephone, cable and sewer lines, streets, and bridges) that are located in flood prone areas;
6.
Minimize damage to private and public property due to flooding;
7.
Make flood insurance available to the community through the National Flood Insurance Program;
8.
Maintain the natural and beneficial functions of floodplains;
9.
Help maintain a stable tax base by providing for the sound use and development of flood prone areas; and
10.
Ensure that potential buyers are aware that property is in a Special Flood Hazard Area.

5.
Additions/Improvements.
(a)
Additions and/or improvements to pre-FIRM structures when the addition and/or improvements in combination with any interior modifications to the existing structure are:
(i)
Not a substantial improvement, the addition and/or improvements must be designed to minimize flood damages and must not be any more non-conforming than the existing structure.
(ii)
A substantial improvement, with modifications/rehabilitations/improvements to the existing structure or the common wall is structurally modified more than installing a doorway, both the existing structure and the addition must comply with the standards for new construction.
(b)
Additions to pre-FIRM or post-FIRM structures that are a substantial improvement with no modifications/rehabilitations/improvements to the existing structure other than a standard door in the common wall, shall require only the addition to comply with the standards for new construction.
(c)
Additions and/or improvements to post-FIRM structures when the addition and/or improvements in combination with any interior modifications to the existing structure are:
(i)
Not a substantial improvement, the addition and/or improvements only must comply with the standards for new construction consistent with the code and requirements for the original structure.
(ii)
A substantial improvement, both the existing structure and the addition and/or improvements must comply with the standards for new construction.

Any combination of repair, reconstruction, rehabilitation, addition or improvement of a building or structure taking place during a one-year period, the cumulative cost of which equals or exceeds 50 percent of the market value of the structure before the improvement or repair is started must comply with the standards for new construction. For each building or structure, the one-year period begins on the date of the first improvement or repair of that building or structure subsequent to the effective date of this ordinance. Substantial damage also means flood-related damage sustained by a structure on two separate occasions during a 10-year period for which the cost of repairs at the time of each such flood event, on the average, equals or exceeds 25 percent of the market value of the structure before the damage occurred. If the structure has sustained substantial damage, any repairs are considered substantial improvement regardless of the actual repair work performed. The requirement does not, however, include either:
(i)

When the increase in the velocity of stormwater runoff resulting from a land-disturbing activity is sufficient to cause accelerated erosion of the receiving watercourse, plans must include measures to control the velocity to the point of discharge so as to minimize accelerated erosion of the site and increased sedimentation of the stream.
12.4.4 Mandatory Standards for Land-Disturbing Activity.
No land-disturbing activity subject to the control of this section shall be undertaken except in accordance with the following mandatory standards:
A.
Buffer Zone around Water Bodies.
1.
No land disturbing activity during periods of construction or improvement to land shall be permitted in proximity to a lake or natural watercourse unless a buffer zone is provided along the margin of the watercourse of sufficient width to confine visible siltation within the twenty-five (25%) percent of the buffer zone nearest the land-disturbing activity.
2.
Waters that have been classified as trout waters by the state environmental management commission shall have an undisturbed buffer zone twenty-five (25) feet wide or of sufficient width to confine visible siltation within the twenty-five (25) percent of the buffer zone nearest the land-disturbing activity, whichever is greater. Provided, however, the town may approve plans which include land-disturbing activity along trout waters when the duration of the disturbance would be temporary and the extent of the disturbance would be minimal. This subsection shall not apply to land-disturbing activity in connection with the construction of facilities to be located on, over, or under a lake or natural watercourse.
3.
Unless otherwise provided, the width of a buffer zone is measured from the edge of the water to the nearest edge of the disturbed area, with the twenty-five (25) percent of the strip nearer the land-disturbing activity containing natural or artificial means of confining visible siltation.

2.
Where relocation of a stream forms an essential part of the proposed activity, the relocation shall minimize unnecessary changes in the stream flow characteristics, except when justification for significant alteration to flow characteristic is provided.
G.
Access and Haul Roads: Temporary access and haul roads, other than public roads, constructed or used in connection with any land-disturbing activity shall be considered a part of such activity.
H.
Borrow and Waste Areas.
1.
When the person conducting the land-disturbing activity is also the person conducting the borrow or waste disposal activity, areas from which borrow is obtained and which are not regulated by the provisions of the North Carolina Mining Act of 1971, and waste areas for surplus materials other than landfills regulated by the North Carolina Department of Environmental, Health and Natural Resources, Division of Solid Waste Management shall be considered as part of the land-disturbing activity where the borrow material is being used or form which the waste material originated.

3.
The formal plan shall indicated if there will be borrowed or waste fill material used or deposited, where it originated or where it will be deposited, and what erosion control measures will be used to stabilize it.
12.4.5 Maintenance Requirements.
A.
No land disturbing activity during periods of construction or improvement to land shall be permitted in proximity to a lake or natural watercourse unless a buffer zone is provided along the margin of the watercourse of sufficient width to confine visible siltation within the twenty-five (25%) percent of the buffer zone nearest the land-disturbing activity or 25 feet wide, whichever is greater. During the development of a site, the person conducting the land-disturbing activity shall install and maintain all temporary and permanent erosion and sedimentation control measures as required by the approved plan or any provision of the North Carolina Sedimentation Pollution Control Act, these regulations, or other local ordinances.
B.
After site development, the land owner or persons in possession or control of the land shall install and/or maintain all necessary permanent erosion and sediment control measures, except those measures installed within a road or street right-of-way or easement and which are accepted for maintenance by a governmental agency.
C.
When sediment is transported onto a public road surface, the road shall be cleaned thoroughly at the end of each day. Sediment shall be removed from the roads by shoveling or sweeping and transported to a sediment control disposal area. Street washing shall be allowed only after sediment is removed in this manner.
D.
If the town must clean up off-site sedimentation or mitigate other erosion related public safety and environmental hazards, the person in violation will be charged for the cost of the cleanup in addition to the civil penalty that may be charged. The cleanup cost shall include personnel costs, equipment usage, and related administrative overhead. If the violator does not pay for the clean-up cost, revoked permits shall not be reissued and a lien shall be place on the violator's property until the cost is recouped by the town.
It is hereby determined that:
• This section shall be officially known as "the stormwater ordinance." It is referred to herein as "this section."
• 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 which 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.
Therefore, the Town of Waynesville has established this set of water quality and quantity regulations to meet the requirements of state and federal law regarding control of stormwater runoff and discharge.
12.5.1 Purpose.
The purpose of this section 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, as well as illicit discharges into the Town of Waynesville's municipal stormwater systems. 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. These requirements establish stormwater management requirements and controls to prevent surface water quality degradation to the extent practicable in the streams and lakes within the Town Limits and Extraterritorial Jurisdiction of Waynesville. This Section seeks to meet this purpose by fulfilling the following objectives:
• Minimize increases in stormwater runoff from new development or redevelopment to the maximum extent practicable for the applicable design storm in order to reduce flooding, siltation, streambank erosion, increases in stream temperature, and to maintain the integrity of stream channels and aquatic habitats.
• Minimize increases in non-point and point source pollution caused by stormwater runoff from development or redevelopment that would otherwise degrade local water quality. Minimize the total volume of surface water runoff that flows from any specific site during and following development in order to replicate pre development hydrology to the maximum extent practicable through the use of structural and nonstructural stormwater management Best Management Practices (BMPs).
• Establish minimum post development stormwater management standards and design criteria for the regulation and control of stormwater runoff quantity and quality.
• Establish design and review criteria for the construction, function, and use of structural stormwater BMPs (also called stormwater control measures, or SCMs) that may be used to meet the minimum post-development stormwater management standards.
• Ensure that structural and nonstructural stormwater BMPs are properly maintained and pose no threat to public health or safety.
• 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.
• Control illicit discharges into the municipal separate stormwater system.

12.5.5 Application Procedures and Requirements.
Cross Reference: Permit Procedures: See 15.7.3
Variance: See 15.13
12.5.6 Design Manual.
A.
Reference to Design Manual: The Town of Waynesville shall use the policy, criteria, and information, including technical specifications and standards, in the North Carolina Department of Environmental Quality (NC DEQ) Stormwater Design Manual as the basis for decisions about stormwater plans and about the design, implementation, and performance of structural and non-structural stormwater control measures.
The Design Manual includes a list of acceptable stormwater treatment practices, including specific design criteria for each stormwater practice. Stormwater treatment practices that are designed, constructed, and maintained in accordance with these design and sizing criteria will be presumed to meet the minimum water quality performance standards of the Phase II and other applicable stormwater laws.
B.
Right to Consult: Stormwater management practices that are designed, constructed, or maintained in accordance with the Stormwater Design Manual are presumed to comply with these requirements. However, the Stormwater Administrator shall have the right to consult duly qualified professionals to impose any conditions or require any modifications deemed necessary to meet the purpose, intent, and requirements of this section.
C.
Relationship of Design Manual to Other Laws and Regulations: If the specifications or guidelines of the Design Manual are more restrictive or apply a higher standard than other laws or regulations, that fact shall not prevent application of the specifications or guidelines in the Design Manual.
D.
Changes to Standards and Specifications: If the standards, specifications, guidelines, policies, criteria, or other information in the Design Manual are amended subsequent to the submittal of an application for approval pursuant to this ordinance but prior to approval, then Section 15.16.1-Permit Choice will apply.
12.5.7 Standards.
A.
General Requirements:
1.
A Stormwater Management System Concept Plan is required for all development and redevelopment projects to which this section applies. This plan shall be prepared by a licensed professional engineer or landscape architect and meet the design specifications of the Town of Waynesville in addition to those standards set forth in this section. See Section 15.7.3 for the specific application process.
2.
The use of natural vegetation and creative landscaping in establishing stormwater control measures is required if applicable. A developer must incorporate the use of natural topography and land cover such as wetlands, ponds, natural swales as they exist prior to development to the degree that they can accommodate the additional flow of water.
3.
Developers are required to use the aforementioned natural measures as well as other BMPs (pervious pavement, discontinuous imperviousness, etc.) in developing property in the town's jurisdiction for the purpose of cleansing and diffusing surface water flow.
4.
Developments shall be designed and constructed with a positive drainage flow away from buildings towards approved stormwater management facilities.
5.
No utilities or habitable structures may be located within any impoundment area of any stormwater management facility. Structures may not be located over a storm drainage line.
6.
All stormwater management facilities will be considered permanent.
7.
[Reserved.]
8.
No stormwater structure, or part thereof, shall project into the property setbacks as established for each zoning district in Section 2.4 Dimensional Standards. If there is no setback or setback is less than 10 feet, then use a minimum distance of 10 feet from the perimeter lot line to a stormwater structure or any part thereof.
9.
Fencing: All sections of stormwater structures shall be surrounded with a permanent, continuous fence or vegetation barrier at the top of the embankment with no opening wider than two (2) inches if a stormwater structure contains:
• A proposed retaining wall higher than 4 feet, and/or
• A 3:1 slope, and/or
• A slope height from the toe of the SCM to the crest is greater than 5 feet.
Any stormwater structure with a continuous fence around the entire perimeter shall provide ingress and egress for SCM/pond maintenance but restricted by lockable gates of adequate size to allow for the easy passage of necessary maintenance equipment. Fences shall be shown on all as-built plans.
10.
Signage: Any SCM that is designed as a pond must have warning signs posted for public visibility and at any major approach to the pond, identifying the area as a stormwater management site to raise public awareness of potential hazards of the site (i.e., no swimming, boating, skating, unsafe to enter, etc.).
11.
Conversion to Stormwater Management Structure: After permanent stabilization of all disturbed contributory drainage areas and flushing of the storm drains, temporary sediment basins, if initially built and certified to meet permanent standards, may be converted to permanent stormwater management structures. To convert the basin from temporary to permanent use, the outlet structure must be modified in accordance with approved stormwater management design plans and inspected for watertight connections. Sediment and other debris should be removed to a contained spoil area. Regrading of the basin may be necessary to achieve the final design grades and to provide an adequate topsoil layer to promote final stabilization. Final elevations and a complete description of any modifications to the riser structure's geometry should be shown on the approved plans.
B.
Water Quality Design Requirements:
1.
All Low Density projects and High Density projects must have the built-upon area at a minimum of thirty (30) feet landward of all perennial and intermittent surface waters. This distance shall be measured horizontally from the edge of water. A perennial or intermittent surface water shall be deemed 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 (USDA) or the most recent version of the 1:24,000 scale (7.5 minute) quadrangle topographic maps prepared by the United States Geologic Survey (USGS). An exception to this requirement may be allowed when site-specific determination is made using NC Division of Water Quality-approved methodology.
2.
In addition to the standards for stormwater management set out in this section, development and redevelopment that drains in whole or part to class TR waters shall design and implement stormwater best management practices that do not result in a sustained increase in the receiving water temperature, while still meeting the other requirements of this section.
3.
The stormwater approval issued shall require recorded deed restrictions and protective covenants to ensure that future development activities maintain the stormwater management measures consistent with the approved project plans.
4.
All Low Density Project sites must employ LID practices to analyze the infiltration capacity and natural drainages of the site and develop a system of controls which mimic the existing natural hydrology and which cumulatively capture and treat the runoff from the 1-year 1-hour storm event. Wherever LID practices are not achievable, or have not been demonstrated, the stormwater management measures shall be designed to control the stormwater runoff according to the requirements of this section.
5.
All High Density projects, for both LID and conventional design approaches, shall include stormwater management measures designed to control the stormwater runoff according to the requirements of this section.
C.
Standards for Stormwater Control Measures:

1.
All structural stormwater control measures shall control and treat the runoff from the 1-year 1-hour storm event as determined by NOAA data for the Town of Waynesville.
2.
All structural stormwater treatment management measures shall be designed to have an eighty-five (85) percent average annual removal for total suspended solids (TSS).
3.
Areas designated as open space that are not or will not be disturbed, developed or redeveloped do not require stormwater runoff treatment.
4.
Where any stormwater management treatment measure utilizes a temporary water quality storage pool as a part of its designed treatment system:
a.
The drawdown time shall be a minimum of 48-hours and a maximum of 120-hours.
b.
The minimum draw down orifice size shall be 2-inches or equivalent.
c.
The post development peak flow rates discharged shall not exceed the pre development 1-year 24 hour peak discharge rates.
5.
No one BMP shall receive runoff from an area greater than three (3) acres. However, the total drainage area from BMPs used in series (i.e., integrated) can exceed this three (3) acre maximum.
6.
Water quality BMPs may encroach into a required buffer as long as the encroachment does not disturb the majority of existing vegetation. Minor understory may be disturbed in order to accommodate water quality structures. Trees and shrubs shall be placed to maximize screening where the encroachment takes place.
7.
General engineering for all projects shall be in accordance with 15A NCAC 2H.1008(c).
8.
All stormwater control measures and stormwater treatment practices required under this ordinance shall be evaluated by the Stormwater Administrator according to the policies, criteria, and information, including technical specifications, standards, and the specific design criteria for each stormwater practice, in the Design Manual. The Stormwater Administrator shall determine whether proposed SCMs/BMPs will be adequate to meet the requirements of this ordinance.
D.
Water Quantity Design Requirements:
1.
For any development to which this section applies, stormwater management facilities, structures, devices and methods shall be designed and built with sufficient capacity to accommodate surface runoff caused by the development in excess of that runoff which would occur from the site if left in its pre development condition.
2.
The calculated difference in the peak runoff rate from the post development peak flow rates, less the pre-development shall determine the size of detention structures.
3.
The storage shall be sufficient to store all excess surface runoff up to the 10-year 24-hour storm event.
4.
The post development peak flow rates discharged from any development that this section applies, shall not exceed the pre development peak discharge rates for the 2-year, 24-hour storm event and the 25-year, 24-hour storm event.
5.
The temporary storage capacity shall be restored within 72 hours.
6.
The emergency overflow outlet must be designed to safely pass the 50-year, 24-hour storm event peak discharge.
7.
Requirements of the Dam Safety Act shall be met when applicable.
8.
No one stormwater management facility shall receive runoff from a developed or redeveloped area greater than three (3) acres. However, the total drainage area from BMPs used in series (i.e., integrated) can exceed this three (3) acre maximum.
9.
The impoundment of stormwater runoff may be incorporated in the design of stormwater conveyance structures, engineered stormwater BMPs, and ponds. These structures may be located on or off site.
10.
In all instances engineered stormwater management facilities and devices shall be designed to complement a development and the surrounding community. If ponds are used, such areas shall be landscaped as amenities or hidden from view.
E.
Stormwater Conveyance Systems Design Requirements:
1.
Stormwater collection systems (drainage parallel to road, including ditches, swales and pipes) shall be designed to pass the peak flows from the 2-year, 24-hour storm event. The minimum allowable pipe size is 15-inches.
2.
Cross drainage systems that do not convey intermittent or perennial streams shall be designed to pass the peak flow rates from the 10-year, 24-hour storm event.
3.
Cross drainage systems conveying intermittent or perennial streams, shall be designed pass peak flow rates for the 50-year, 24-hour storm event. These structures shall consist of bottomless single span structures.
4.
Inlet capacity and spread calculations must be provided. Roadway inlet locations, capacities, gutter spread, and storm drain pipe system shall be analyzed and designed using a 10-year discharge with a minimum time of concentration of 10 minutes. An intensity of 4 inches/hour should be used for calculating spread and determination of appropriate locations for inlet placement to collect roadway pavement runoff.
5.
It is desirable that inlets be designed for 100% interception of runoff, but minor bypass discharge to a downstream inlet is acceptable if it is accounted for in design computations.
6.
On grades, the curb opening can be ignored in determining inlet capacity. The grate efficiency may be assumed to equal that of a parallel bar grate.
7.
Inlet capacity at sags should allow for debris blockage by providing twice the required computed opening (i.e., assume 50% blockage).
8.
Inlet spacing shall be sufficient to limit spread as required for safe vehicle maneuverability. Allowable spread into the travel lane during temporary conditions (detours, phased construction, etc.) should be evaluated based on factors, such as traffic volume, road classification, posted speed limit, and lane width. For curb and gutter sections (with no side parking or bike lanes), the width of the gutter pan is considered the "shoulder."
9.
If the design speed is less than or equal 45 mph, then the allowable spread is up to half the travel lane. If the design speed is greater than 45 mph, the allowable spread shall maintain in the shoulder.
10.
All storm drain grates shall be perpendicular to the travel way.
F.
Uniform Watershed Analysis:
1.
Uniform Watershed Analysis is required for all developments. Calculations must be developed to show the development's impact on the greater watershed.
2.
The requirements, or portions thereof, for detention may be waived by the Stormwater Administrator if it can be shown by detailed engineering calculations and analysis which are acceptable to the Administrator that one of the following exists:
a.
The installation of stormwater management facilities would have insignificant effects on reducing downstream flood peak flow rates and water surface elevations.
b.
Stormwater management facilities are not needed to protect downstream developments and the downstream drainage system has sufficient capacity to receive any increase in runoff for the design storm.
c.
It is not necessary to install stormwater management facilities to control post development peak discharge rates at the exit to a proposed development and installing such facilities would increase flood peak flow rates and or water surface elevations at some downstream locations.
d.
The Administrator determines that stormwater management facilities are not needed to control post development peak discharge rates and installing such facilities would not be in the best interest of the Town.
3.
The requirements, or portions thereof, of this section may not be waived if the Administrator determines that not controlling peak flow rates would increase known flooding problems, or exceed the capacity of the downstream drainage system.
4.
A waiver shall only be granted after a written request is submitted by the applicant containing descriptions, drawings, and any other information that is necessary to evaluate the proposed development or redevelopment. A separate written waiver request shall be required if there are subsequent additions, extensions, or modifications which would alter the approved stormwater runoff characteristics of the development or redevelopment receiving a waiver.
5.
Discharge velocities shall be reduced to provide a non-erosive velocity flow from a structure, channel, or other control measure or the velocity of the 2-year 24-hour design storm runoff in the receiving waterway prior to the development, whichever is greater.
6.
For all stormwater management facilities, a hydrologic/hydraulic study shall be conducted showing how the drainage system will function with and without the proposed facilities. For such studies the existing and developed land use conditions shall be used. Existing land use data shall be taken from the most recent aerial photograph and field checked and updated.
7.
For the design of the facility outlet structure, use developed land use conditions for the area within the proposed development and existing land use conditions for upstream areas draining to the facility.
8.
For any analysis of flood flows downstream from the proposed development, use existing land use conditions for all downstream areas.
12.5.8 Exceptions to the 30-Foot Setback.
Exceptions from the 30-foot landward location of built-upon area requirement of all perennial and intermittent surface waters as well as the deed restrictions and protective covenants requirements shall be granted by the Administrator in any of the following instances:
A.
When there is a lack of practical alternatives for a road crossing, railroad crossing, bridge, airport facility, or utility crossing (including water, sewer, or gas construction and maintenance corridors) as long as it is located, designed, constructed, and maintained to minimize disturbance, provide maximum nutrient removal, protect against erosion and sedimentation, have the least adverse effects on aquatic life and habitat, and protect water quality to the maximum extent practicable through the use of BMPs.
B.
When there is a lack of practical alternatives for a stormwater treatment measures. A lack of practical alternatives may be shown by demonstrating that, considering the potential for a reduction in size, configuration, or density of the proposed activity and all alternative designs, the basic project purpose cannot be practically accomplished in a manner which would avoid or result in less adverse impact to surface waters.
1.
These measures shall be located, designed, constructed, and maintained to minimize disturbance, provide maximum nutrient removal, protect against erosion and sedimentation, have the least adverse effects on aquatic life and habitat, and protect water quality to the maximum extent practicable.
2.
The implementation of the alternative stormwater treatment measures shall not disturb existing vegetation.
3.
Minor understory trees may be disturbed in order to accommodate these measures. Trees and shrubs shall be placed to maximize screening where the encroachment takes place.
12.5.9 Illicit Discharges and Connections.
A.
Illicit Discharges: No person shall cause or allow the discharge, emission, disposal, pouring, or pumping directly or indirectly to any stormwater conveyance, the waters of the State, or upon the land in manner or amount that the substance is likely to reach a stormwater conveyance or the waters of the State unless permitted by an NPDES permit. Prohibited instances include but are not limited to: anti-freeze, chemicals, animal waste, paints, garbage, and litter. However, non-stormwater discharges associated with the following activities are allowed provided that they do not significantly impact water quality:

B.
Illicit Connections: Connections to a stormwater conveyance or stormwater conveyance system which allow the discharge of non-stormwater, other than the exclusions described in subsection 12.5.11.A above, are unlawful. Prohibited connections include, but are not limited to: industrial/commercial floor drains, waste water from washing machines or sanitary sewers, wash water from commercial vehicle washing or steam cleaning, and waste water from septic systems.
1.
Prior Illegal Connections To Cease Within One (1) Year: Where connections exist in violation of this section and said connections were made prior to the adoption of this provision or any other ordinance prohibiting such connections, the property owner or the person using said connection shall remove the connection within one (1) year following application of this regulation.
2.
Hazardous Material Connections to Cease Immediately: The aforementioned one (1) year grace period shall not apply to connections that result in the discharge of hazardous material. Nor shall the grace period apply to other discharges which pose an immediate threat to health and safety, or are likely to result in immediate injury and harm to real or personal property, natural resources, wildlife or habitat. For such connections, the Public Works Director shall designate the time within which the connection shall be removed. In setting the time limit for compliance, the director shall take into consideration: the quantity and complexity of the work; the consequences of delay; the potential harm to the environment, public health and to public and private property; and, the cost of remedying the damage.
C.
Spills: Spills or leaks of polluting substances released, discharged to, or having the potential to released or discharged to the stormwater conveyance system, shall be contained, controlled, collected, and properly disposed. All affected areas shall be restored to their preexisting condition.
Persons in control of the polluting substances immediately prior to their release or discharge, and persons owning the property on which the substances were released or discharged, shall immediately notify the Town of Waynesville of the release or discharge, as well as making any required notifications under state and federal law. Notification shall not relieve any person of any expenses related to the restoration, loss, damage, or any other liability which may be incurred as a result of said spill or leak, nor shall such notification relieve any person from other liability which may be imposed by State or other law.
12.5.10 Operations and Maintenance Agreement.
A.
Private Development: Prior to the conveyance or transfer of any private lot or building site to be served by a structural BMP pursuant to this section and prior to issuance of any permit for development or redevelopment requiring a structural stormwater BMP pursuant to this section, the applicant or owner of the site must execute an operation and maintenance agreement that shall be binding on all subsequent owners of the site, portions of the site, and lots or parcels served by the structural BMP. Until the transference of all property, sites, or lots served by the structural BMP, the original owner or applicant shall have the primary responsibility for carrying out the provisions of the maintenance agreement.

Escrowed funds may be spent by the association for sediment removal, structural, biological or vegetative replacement, major repair, and reconstruction of the structural BMPs, provided that the Stormwater Administrator shall first consent to the expenditure.
4.
Both developer contribution and annual deposits for future use of "sinking funds" shall fund the escrow account. Prior to plat recordation or issuance of construction permits, whichever shall first occur, the developer shall pay into the escrow account an amount equal to fifteen percent (15%) of the initial construction cost of the structural BMPs. Two-thirds (⅔) of the total amount of sinking fund budget shall be deposited into the escrow account within the first five (5) years and the full amount shall be deposited within ten (10) years following initial construction of the structural BMPs. Funds shall be deposited each year into the escrow account to cover the cost of maintenance. A portion of the annual assessments of the association shall include an allocation into the escrow account. Any funds drawn down from the escrow account shall be replaced in accordance with the schedule of anticipated work used to create the sinking fund budget.
5.
The percent of developer contribution and lengths of time to fund the escrow account may be varied by the Town depending on the design and materials of the stormwater control and management facility.
6.
Granting to the Town a right of entry to inspect, monitor, maintain, repair, and reconstruct structural BMPs.
7.
Allowing the Town to recover from the association and its member's any and all costs the Town expends to maintain or repair the structural BMPs or to correct any operational deficiencies. Failure to pay the Town of its expended costs, after forty-five (45) days' written notice, shall constitute a breach of the agreement. The Town shall thereafter be entitled to bring an action against the association and its members to pay, or foreclose upon the lien hereby authorized by the agreement against the property, or both, in case of a deficiency. Interest, collection costs, and attorney fees shall be added to the recovery.
8.
A statement that this agreement shall not obligate the Town to maintain or repair any structural BMPs, and that the Town shall not be liable to any person for the condition or operation of structural BMPs.
9.
A statement that this agreement shall not in any way diminish, limit, or restrict the right of the Town to enforce any of its ordinances as authorized by law.
10.
A provision indemnifying and holding harmless the Town for any costs and injuries arising from or related to the structural BMP, unless the Town has agreed in writing to assume the maintenance responsibility for the BMP and has accepted dedication of any and all rights necessary to carry out that maintenance.
D.
Agreement Requirements:
1.
The operation and maintenance agreement shall require the owner or owners to maintain, repair, and, if necessary, reconstruct the structural BMP and shall state the terms, conditions, and schedule of maintenance for the structural BMP. In addition, it shall grant The Town of Waynesville a right of entry in the event that the Stormwater Administrator has reason to believe it has become necessary to inspect, monitor, maintain, repair, or reconstruct the structural BMP; however, in no case shall the right of entry, of itself, confer an obligation on The Town of Waynesville to assume responsibility for the structural BMP.
2.
The operation and maintenance agreement must be approved by the Stormwater Administrator prior to plan approval and it shall be referenced on the final plat and shall be recorded with the Haywood County Register of Deeds upon final plat approval.

D.
Records of Installation and Maintenance Activities: The owner of each structural BMP shall keep records of inspections, maintenance, and repairs for at least five years from the date of creation of the record and shall submit the same upon reasonable request to the Stormwater Administrator.
E.
Nuisance: The owner of each stormwater BMP, whether structural or non-structural BMP, shall maintain it so as not to create or result in a nuisance condition.
12.5.12 Performance Security.
The Town of Waynesville may, at its discretion, require the submittal of a performance security or bond with surety, cash escrow, letter of credit or other acceptable legal arrangement prior to issuance of a permit in order to ensure that stormwater BMPs are installed as required by the approved stormwater management plan, and are maintained by the owner as required by the operation and maintenance agreement.
A.
Amount:
1.
The amount of an installation performance security shall be the total estimated construction cost of the BMPs approved under the permit, plus 25%.
2.
The amount of a maintenance performance security shall be the present value of an annuity of perpetual duration based on a reasonable estimate of the annual cost of inspection, operation and maintenance of the BMPs approved under the permit, at a discount rate that reflects the jurisdiction's cost of borrowing minus a reasonable estimate of long-term inflation.
B.
Forfeiture: The performance security shall contain forfeiture provisions for failure, after proper notice, to complete work within the time specified, or to initiate or maintain any actions which may be required of the applicant in accordance with this section.
C.
Default: Upon default of the applicant to construct, maintain, repair, and if necessary reconstruct any stormwater device in accordance with the applicable permit, the Stormwater Administrator shall obtain and use all or any portion of the security to make necessary improvements based on an engineering estimate. Such expenditure of funds shall only be made after requesting the applicant to comply with the permit. In the event of a default triggering the use of installation of performance security, the Town of Waynesville shall not return any of the unused deposited cash funds or other security, which shall be retained for maintenance.
D.
Cost in Excess of Performance Security: If the Town of Waynesville takes action upon such failure by the applicant, the Town may collect the difference should the amount of the reasonable cost of such action exceed the amount of the security held. This difference will be collected from the applicant.
E.
Refund: Within sixty (60) days of the final approval, the installation performance security shall be refunded to the applicant or terminated, except any amount attributable to the cost (plus 25%) of landscaping installation and ongoing maintenance associated with the BMPs covered by the security. Any such landscaping shall be inspected one (1) year after installation with replacement for compliance with the approved plans and specifications and, if in compliance, the portion of the financial security attributable to landscaping shall be released.
12.5.13 Additional Standards for Special Situations.
A.
Trout Waters: In addition to the standards for handling stormwater set out in the Design Manual, development and redevelopment that drains in whole or part to class TR waters shall design and implement the best stormwater practices that do not result in a sustained increase in receiving water temperature, while still meeting the other requirements of this ordinance.
B.
Pet Waste: Pet waste can pollute rivers, streams, and lakes. Stormwater runoff carries pet waste into drainage ditches and storm drains where it is then dumped, untreated, into the nearest waterway. Dog waste contains bacteria, viruses, and parasites that can harm humans and affect water quality. Once in a waterway, pet waste can travel long distances and pollute a large area. Therefore:
• It shall be unlawful for the owner or custodian of any dog to take it off the owner's own property limits without the means to properly remove and dispose of the dog's feces from any public or private property.
• It is the responsibility of a dog's owner or custodian to clean up the dog's feces from any public or private property outside of the dog's owner's own property limits. Such property includes, but is not limited to, parks, rights-of-way, paths, and public access areas.
• "Means to properly remove and dispose of feces" shall consist of having on or near ;hg;one's person a device such as a plastic bag, or other suitable plastic or paper container, that can be used to clean up and contain dog waste until it can be disposed of in an appropriate container.
• This provision shall not apply to handicapped persons assisted by trained guide or assistance dogs.

12.6.1 Purpose.
The purpose of this section is to regulate development in steep slope areas in order to preserve the Town of Waynesville's unique character, conserve the public health, safety and general welfare and to promote environmentally sound design and planning in accordance with the following objectives:
• To protect life and property from all potentially hazardous conditions particular to steep slopes, e.g., rock falls, flash flooding, debris flows, mud slides and increased wildfire hazard.
• To preserve and enhance the scenic and environmental resources of the landscape by encouraging the maximum retention of prominent natural topographic features, i.e., drainage swales, streams, slopes, ridgelines, rock outcroppings, vistas, natural plant formations, and trees.
• To encourage innovative site and architectural design and planning in order for the development to adapt to the natural terrain and be harmonious with the character of the area.
• To minimize grading and cut and fill operations inconsistent with the retention of the natural character of the hillside.
• To preserve where possible, natural streams, ponds and associated riparian vegetation.
• To require the retention of trees and other vegetation to stabilize steep hillsides, retain moisture, prevent erosion and enhance the natural scenic beauty.
• To encourage the retention of trees and other vegetation throughout the site instead of just the periphery of the development.
• To encourage minimal grading which relates to the natural contour of the land, thus rounding off sharp angles at the top and bottom of cut and fill slopes in a natural manner.
• To provide land use densities to promote the best possible development of hillside areas in order to retain significant natural features and to preserve slope stability.
• To encourage road design that follows the natural topography wherever possible in order to minimize grading.
• To preserve predominant views from and of the hillside areas in order to retain the sense of identity and imagery that the hills and mountains now impart to the Town of Waynesville.
12.6.2 Applicability.
A.
For the purposes of this section, a Steep Slope Area is defined as any lot, parcel, tract or portion thereof, that has a natural elevation of 2,900 feet above mean sea level or higher, with a natural average slope of 25% or greater as determined using the following formula:
S = 0.0023 × I × L
A
Where:
S = Average natural slope of parcel in percent
I = Contour interval of map in feet
L = Total length of contour lines within the parcel in feet
A = Area in acres of the parcel
0.0023 = Constant which converts square feet into acres
B.
In the case of conflict between the average natural slope determination of a lot using different methods of calculation the following methods in shall prevail in the following order: 1) use of the above formula based on field survey data, 2) use of the above formula based on the best available topographic data in the Haywood County Geographic Information system, 3) use of a Town approved geographic information system based slope calculation tool.
C.
Application to properties with an average natural slope of 25% or greater split by the 2,900-foot contour line.
1.
If any portion of the lot above 2,900 feet is placed in a permanent conservation easement or otherwise reserved in perpetuity, the residential density from this portion of the property may be transferred to the remainder of the property below 2,900 feet or to adjacent properties in the same ownership below 2,900 feet at the same ratio as that of the underlying zoning district.
2.
The area above 2,900 feet may be developed as provided for in Table 12.6.4, and the remainder of the property below 2,900 feet or with an average slope below 25% may be developed as permitted in the underlying zoning district.
D.
Reservation of steep slope areas to reduce average slope. Areas placed in a permanent conservation easement, dedicated to the public for open space, protected as open space by restrictive covenants or otherwise permanently protected in a natural state with a prohibition on vegetation removal and land disturbing activity may be excluded from the calculation of the average slope for the property or properties which include the area, provided that the minimum size of each such reserved area shall equal the minimum lot size for the underlying zoning district.
12.6.3 General Steep Slope Area Development Standards.
A.
No land disturbing activity shall take place until full development approval has been received.
B.
Land disturbing activity shall be limited to designated building envelopes and approved road and driveway corridors as shown on approved site plans.
C.
Diversion or channelization of perennial streams shall not be permitted unless without such diversion or channelization a tract existing at the time of adoption of this amendment is rendered unusable for any of the principal uses allowed within the zoning district.
D.
The riparian stream buffers shall be left intact, which means that removal of trees, or other vegetation, or disturbance of soils within this buffer is prohibited, except for necessary road crossings. The buffers shall be a minimum of 30' from the edge of the stream or 25 feet from the top of bank, whichever is greater.
E.
Perennial streams shall not be placed in culverts except to the minimum extent possible for necessary road crossings.
F.
Developers shall make reasonable efforts to preserve and protect existing natural features of the slope, such as trees and other plan material, and rock outcroppings which may help to stabilize the slope.
G.
The maximum area of disturbance per phase shall not exceed 5 acres.
H.
Cut and fill slopes shall comply with the standards of Section 12.4.
I.
Stormwater management shall comply with the standards of Section 12.5.
12.6.4 Specific Steep Slope Area Development Standards.
In addition to any development restriction imposed by the underlying zoning district, the following standards shall apply to any properties that are subject to the standards of this section:
Table 12.6.4
