A-10 Morehead City Storm Drainage System Mapping amec'� page 1-0 Project Summary DRAFT Stormwater Drainage System Mapping I. Pilot Inventory of the Storm Drainage System and Review of Existing GIS Data On March 2, 2002 a pilot inventory of the storm drainage system was conducted within the Extraterritorial Jurisdiction (ETJ) of Morehead City to verify existing Global Information System (GIS) data and to verify the availability of Global Positioning System (GPS) satellites. Existing GIS maps were compared to the actual system and the locations of structures were visually verified. General storm drainage problem areas and those areas needing additional data were noted. The Existing GIS data showed that the existing storm drainage maps contained only storm drainage structures and associated piping. The pilot inventory showed that the ETJ's drainage system is predominately characterized by roadside swales with driveway pipes. It is at points where the system of driveway pipes and swales are connected to the adjacent storm drainage systems that storm drainage structures and associated structures are found. The GPS receivers were tested during the pilot inventory. Several storm drainage features were mapped at various locations throughout the ETJ and compared to existing GIS data. In summary the Pilot Inventory provided the following information: 1. GPS receivers function with the associated software databases. 2. The ETJ storm drainage system needs to have the existing data updated and an extensive amount of additional data needs to be conducted. 3. The storm drainage system within the ETJ is primarily characterized by driveway pipes and roadside swales. 4. A large percentage of driveway pipes that are present are undersized (6 inches or less) and made out of plastic. 5. A few residential developments within the ETJ have a "curb and gutter" type storm drainage system with associated inlets and piping. These systems are localized and discharge either to Waters of the State or a system of interconnecting swales. II. Storm Drainage System Mapping To fulfill portions of the grant provided by the North Carolina Coastal Management Program, five students were recruited from East Carolina University to assist with the storm drainage mapping portion of the project. Training for the students was conducted on Sunday March 10, Morehead City Storm Drainage System Mapping amee'� Project Summary page 1-1 DRAFT 2002 in Morehead City. The training focused on recognizing specific storm drainage features, how to collect the data and how to record the data in the correct database fields. Training was also provided on how to recognize, classify and record possible storm drainage system problem areas including: illicit connections to the storm drainage system, structural problems, sediment problems, blockage problems and general maintenance problems. Mapping of the storm drainage system was initiated on March 1Ith. Several data collection teams were created using AMEC staff paired with one or more students. Field data collection was completed on 23 March 2002. III. Storm Drainage System Data Collection Storm drainage data was collected and recorded to a computerized database using Tremble GPS backpack units connected to Personnel Data Assistants (PDA) loaded with TerraSync °n software. Data collection was divided amongst the team members with each team member having a specific responsibility. One team member was responsible for collecting the GPS location data and entering data into the computerized database, one team member was responsible making a backup of the data by writing it on a hard copy map, and one team member was responsible for taking measurements and determining the condition of the structure or conveyance. At the end of each day, the data collected by each team was downloaded to a desktop computer using Tremble GPS Pathfinder Office version 2.80 and an initial quality assurance check of the data was performed looking for incomplete data fields, system connectivity, etc. Completed hardcopy maps were collected for later comparison to the computerized database during the final QA/QC processes. Data collected by the field teams was dived into four categories: Structures, Conveyances, Non- Stormwater Discharges, and Best Management Practices. The Individual attributes are listed in Appendix A. IV Data Collection Quality Assurance Review After data collection was completed, a Quality Assurance Review of the collected data was performed. The data review compared the electronic data collected with the hardcopy field maps as well as digitizing in creeks and swales that were inaccessible. System wide connectivity was reviewed and established based on a combination of GIS data collected, field interviews with local citizens, field maps, existing GIS data and topographic maps. Isolated storm drainage systems were encountered and if no connectivity could be established or if other problems usually associated with isolated system were found (such as standing water) then the storm drainage systems were left as they were mapped. Morehead City Storm Drainage System Mapping amen page 1-2 Project Summary DRAFT V Data Collection Statistics 5,314 Structures and 5,017 Conveyances, 125 Non -Storm Discharges and 11 BMPs were mapped. The total length of the system as mapped is 716,050 feet or just over 136 miles of pipes, swales, creeks and ponds. Of the 5,017 Conveyances mapped, 410 or 8% have a blockage problem, 698 or 14% have a ponding problem, 46 or 0.9% are possible non-stormwater discharges, and 39 or 0.8% have a structural problem. The remaining Conveyances are either listed as having no observed problems (3,716 - 74%) or are listed as unknown (108 — 2%). Of the 5,314 Structures mapped 459 or 8% have a blockage problem, 1 has an erosion problem, 323 or 15% have a ponding problem, 60 or 1% have a possible non-stormwater discharge, and 77 or 1% have a structural problem. The rest are listed as having no observed problem (3,654 - 67%) or are listed as unknown (740 —14%). 125 Non-Stormwater connections were mapped. These points as well as the 60 possible non- stormwater discharges should be further investigated. If they are non-stormwater discharges then these connections to the storm drainage system should be removed. Morehead City Storm Drainage System Mapping ame{r page J Project Summary DRAFT Appendix A - Storm Drainage Mapping Databases Data collected by the field teams was dived into four categories: Structures, Conveyances, Non Stormwater Discharges, and Best Management Practices. The Individual attributes are described below. Computerized Database for Storm Drainage System Structures The Storm Drainage System Structures were split up into thirteen different categories listed below. ➢ Bridge End ➢ Manhole/ Junction Box ➢ Curb Inlet — No Grate ➢ Curb inlet — Grate ➢ Control Structure ➢ Open Throat Catch Basin ➢ Curb Cut ➢, Grate ➢ Headwall ➢ Conveyance End ➢ Pipe End ➢ Hidden Junction Box ➢ Other -See Comments Each is Described Below Bridge End Bridge Ends are used where a significant bridge crosses a swale or stream. It is used primarily for display purposes so that when the coverages are viewed in ArcView with the associated aerial photographs as a backdrop, water does not appear to flow "over the bridge". Manhole/Junction Box Manhole/ Junction Boxes are structures that do not allow stormwater to enter them except by way of stormwater pipes. Usually the only access to .these types of structures is by way of a manhole cover or removable solid concrete top. Curb Inlet — No Grate and Curb Inlet — Grate Curb inlets — No Grate are characterized by a structure that primarily allows storm drainage to enter the structure by way of a rectangular vertical opening and they are usually collocated with curb and gutter. If the structure has a grate placed horizontally in front of the opening then that Morehead City Storm Drainage System Mapping page A-1 Appendix A ameO DRAFT structure is called a Curb Inlet — Grate. Control Structure Control Structures are classified as those structures whose sole purpose is to control the rate of storm water discharging through them. The most common types included: riser and barrels, weirs, dams, and emergency spillways. They are usually co -located with retention/ detention ponds. Open Throat Catch Basin Open Throat Catch Basins are characterized by one or (usually) more vertical rectangular openings with either a solid concrete top or a concrete top with a manhole cover. The top of these types of structures is usually supported in each comer by bricks. Usually found in roadside swales or in yards. Curb Cut Curb Cuts are usually co -located with curb and gutter. They are an opening made in the curb that allows storm drainage to discharge through the curb cut and into a natural or man-made swale. Grate A structure that allows storm drainage to enter by passing through a flat horizontal grid is called a Grate. They are usually found in parking lots or in roadways. Headwall A Headwall is described as any form of material purposefully placed at the end of a pipe to prevent erosion and has a basic vertical form. This excludes riprap and vegetative swale linings but includes metal, wood, plastic, sandbag, masonry and concrete construction. Conveyance End A Conveyance End is placed where two or more swales join, a swale ends, or a swale discharges to Waters of the State. Pipe End A Pipe End is placed at the end of a pipe where that pipe joins with a swale or Waters of the State. Pipe Ends may have an "end treatment" such as a flared end section, rip rap, poured concrete, etc. Morehead City Storm Drainage System Mapping Appendix A ameO page A-2 DRAFT Hidden Junction Box A Hidden Junction Box is used where two or more storm drainage pipes appear to connect but you cannot determine the exact location of the structure. This may be due to the structure being buried, paved over or inaccessible. Other -See Comments The structure type Other -See Comments is used when you cannot classify the storm drainage structure into one of the other structure classifications. An entry in one of the comments fields is made that describes the structure. These structures are usually combinations of the structures listed above. An example of this would be a Curb Inlet — Grate, located in curb and gutter, with an opening in the back of the structure like an Open Throat Catch Basin. Other examples would include such combinations as a Curb Cut on the top of a Headwall or a Curb Cut with a Grate. The total amount of Storm Drainage Structures collected is 5,314. The number of each Structure type collected is shown below. Storm Drainage Structure Number Collected Bridge End 2 Other -See Comments 6 Manhole/ Junction Box 22 Curb Inlet — No Grate 25 Control Structure 35 Open Throat Catch Basin 37 Curb Cut 99 Hidden Junction Box 119 Curb inlet — Grate 169 Grate 208 Headwall 211 Conve ance End 729 Pi a End 3,652 Morehead City Storm Drainage System Mapping page Ad AppendizA ameO DRAFT Computerized Database for Storm Drainage System Conveyances The Storm Drainage System Conveyances were split up into eight different categories listed below. ➢ Bridge ➢ Box Culvert ➢ Dry Pond ➢ Hidden Drain ➢ Creek ➢ Wet Pond ➢ Swale ➢ Storm Drain Each is Described Below Bridge Bridges are used where a significant bridge crosses a swale or stream. It is used primarily for display purposes so that when the coverages are viewed in ArcView with the associated aerial photographs as a backdrop, water does not appear to flow `over the bridge". Box Culvert A Box Culvert describes a storm drainage pipe that is rectangular in shape. These structures are usually extremely large and there measurements are recorded in feet instead of inches unless otherwise indicated in the database. Dry Pond Dry Ponds are man-made storm drainage features that retain storm drainage during rainfall events and allow the stormwater to evaporate or infiltrate into the ground. Hidden Drain A Hidden Drain is used to connect two storm drainage structures together where access to the pipe is not possible. Situations where this occurs are; both pipe ends buried by sediment, both pipe ends under water, for connection between Hidden Junction Boxes, no access to each pipe end (i.e. inside a locked fence). Investigative procedures such as transmission of noise through the pipes, tracking of storm drainage flow, best judgment, etc. are used to establish connectivity using Hidden Drains. Morehead City Storm Drainage System Mapping Appendix A am page A -a .rrc�l� Creek Creeks indicate Waters of the State, very large swales or indicate a water flow path through inaccessible areas such as swamps. Wet Pond Wet Ponds indicate a man-made storm drainage feature that retains a permanent pool of water and slowly releases accumulated stormwater to the storm drainage system over a long period of time. Swale A Swale indicates a man-made or natural open channel conveyance that is not classified as Waters of the State. A Swale may be lined with rip rap, concrete, stone, masonry, gabions, etc. or may have a natural lining of bare earth, rock or vegetation. Storm Drain The attribute Storm Drain describes any man-made conveyance that usually conveys stormwater below the surface of the ground. Storm Drains can be made out of metal, concrete, masonry and plastic. The total amount of Storm Drainage Conveyances collected is 5017. The number of each Conveyance type collected is shown below. Storm Drainage Conveyance Number Collected Bride 1 Box Culvert 3 Dry Pond 5 Hidden Drain 38 Creek 65 Wet Pond 86 Swale 2,408 Storm Drain 2,411 Morehead City Storm Drainage System Mapping page AS Appendix A am DRAFT Computerized Database for Non-Stormwater Discharges The Non-Stormwater Discharges were split up into thirteen different categories listed below. ➢ Household HAZMAT ➢ New Construction ➢ Car Washing ➢ Industry Wastewater ➢ Sanitary Sewer ➢ Sediment/ Erosion ➢ Dumping ➢ Solid Waste ➢ Maintenance Activities ➢ Petroleum, Oils and Lubricants (POL) ➢ Laundry Wastewater ➢ Unknown Liquid ➢ Other See Comments Each is Described Below Household HAZMAT Household HAZMAT is used to describe items of hazardous materials typically generated by a residential household -and are dumped into the storm drainage system. These items included; batteries, bleach, insecticides, small quantities of waste and used POLs, household cleaners, paint, etc. New Construction New Construction concerns the general waste items that may be generated by construction activities that are dumped into the storm drainage system. These items include; POLs, batteries, cleaners, paint, light and heavy metals, erosion and sediment transport, construction debris, scrap wood, trash, etc. Car Washing Car Washing refers to possibly contaminated discharges from commercial car washes that enter the storm drainage system. Industry Wastewater Industry Wastewater concerns any discharge from a facility classified as an industrial that reaches the storm drainage system untreated. Morehead City Storm Drainage System Mapping page A-6 Append& A ameO DRAFT Sanitary Sewer Sanitary Sewer concerns untreated raw sewage being discharged to the storm drainage system. Sediment/ Erosion One of the main concerns with Sediment in the storm drainage system is the clogging of storm drainage pipes and sediment transport that can fill swales and negatively affect aquatic life. Erosion can cause severe damage to storm drainage structures as well as damage swale and creek banks. Dumping Dumping concerns the deliberate depositing of one or more waste materials directly into or around the storm drainage system. This usually involves large quantities of material. Dumping can involve liquids, solids, gasses or any combination of these. Dumping is usually used to describe large quantities of trash, urban debris, construction materials, HAZMAT, etc. usually placed in or adjacent to a swale or creek. Solid Wastes Solid Wastes concerns the dumping of wastes that normally would have been accepted at a sanitary landfill. It closely resembles Dumping but the wastes involved are usually only.solid in form. This is used to describe specific waste depositing such as tires, wood, white goods, etc. Maintenance Activities Maintenance Activities usually involves improper waste disposal by a specific maintenance activity. An example of this would be allowing oil to discharge directly into the storm drainage system during an oil change. Another example would be the dumping of old equipment batteries into or adjacent to the storm drainage system. Maintenance activities are very similar to any of the other categories but can be tied to a specific maintenance activity. Petroleum, Oils and Lubricants (POL) Petroleum, Oils and Lubricants (POL) concern the discharge of POLs into the storm drainage system. This can be deliberate or accidental. An example of deliberate would be dumping used oil into a storm drain inlet. An example of accidental would be a railroad derailment where a tank car loaded with POLs discharges its contents into the storm drainage system. Morehead City Storm Drainage System hrapping page A-7 AppendirA ' ame DRAFT Laundry Wastewater Laundry Wastewater concerns a direct connection of household or commercial laundry equipment to the storm drainage system. This is usually found in areas that have septic tanks. Homeowners will run a laundry discharge line directly to the storm drainage system. Other -See Comments Other -See Comments concerns discharges or dumping of unknown substances to the storm drainage system that were not easily classifiable into one of the other non-stormwater discharge classifications or needed additional investigation to confirm the suspected non-stormwater discharge. Unknown Liquid Unknown Liquid concerns a liquid substance being discharged to the storm drainage system that was not easily classifiable into one of the other non-stormwater discharge classifications or needed additional investigation to confirm the suspected non-stormwater discharge. The total amount of Non-Stormwater Discharges collected is 125. The number of each Non- Stormwater Discharge type collected is shown below.

Examples of Structural BMPs are repairing and/or upgrading existing storm drainage structures and conveyances, removing sanitary sewer direct connections to the storm drainage system, removing other Non-Storinwater connections, installing stormwater quality controls such as vegetative buffers, installing storrwater quantity controls such as retention/ detention ponds, etc. Non -Structural The Non -Structural category applies to those BMPs that do not involve the storm drainage structures and conveyances directly but contribute to the quality and quantity of stormwater discharges. Examples of Non -Structural BMPs are public education, stormwater ordinances, procedural changes, stormwater design manuals, existing ordinance revisions, master planning, etc. Wastewater Wastewater is a general term used to describe liquid byproducts generated during industrial activities. Wastewater can include sewage, product rinse water, electroplating solutions, fabric dye, paint, POLs, hazardous chemicals, etc. Wastewater usually requires some form of treatment before being allowed to discharge to the storm drainage system. Alorehead City Storm Drainage System ♦Mapping Appendix A am page A4 WNIFffl— Hazardous Waste Hazardous Waste refers to material handling practices and procedures for materials that become hazardous after there intended uses. Hazardous waste may also have been Hazardous Material before being used. Examples of Hazardous Waste include spent radioactive fuel rods, PCBs, poisons, certain forms of POL products (including waste .oil and contaminated fuel), acids, bases, etc. Hazardous Material Hazardous Material refers to material handling practices and procedures for material that is hazardous in nature before its intended use. Examples of hazardous material include acids, bases, radioactive materials, poisons, etc. Management Management refers to suggested procedural changes, public education, stormwater and other ordinances, etc. Other - See Comments Other - See Comments refers to those BMPs that do not fall into one of the above categories. These may include maintenance issues. The total amount of Best Management Practices collected was 11. The number of each Best Management Practice major category type collected is shown below.

In order to meet these goals, the Town of Morehead City adopts this Stormwater Management Ordinance for the following purposes: a) To regulate new development, redevelopment, and other construction activities within the jurisdiction of the Town, consistent with federal, state and local requirements, and the Town's environmental goals. b) To provide the structure within which the authority of the Town of Morehead City to administer and enforce stormwater quantity and quality regulations will be exercised. Sec. 2. Findings of facts. Development without control of drainage has a significant adverse impact upon the health, safety and welfare of the'community. More specifically: a) Uncontrolled stormwater runoff can carry pollutants into receiving water bodies, degrade water quality and result in adverse impacts to shelifishing waters; b) Uncontrolled stormwater runoff can increase nutrients such as phosphorus and nitrogen, thereby accelerating eutrophication of receiving waters, adversely affecting flora and fauna; c) Improperly channeling water increases the velocity of runoff, thereby increasing erosion and sedimentation; Draft SWM Ordinance 1 Town of Morehead City d) Construction requiring the alteration of natural topography and removal of vegetation tends to cause a loss of natural recharge areas and increase erosion; e) Siltation of water bodies resulting from increased erosion decreases their capacity to hold and to transport water, interferes with navigation, and harms flora and fauna; f) Impervious surfaces increase the volume and rate of stormwater runoff and allow less water to percolate into the soil, thereby decreasing groundwater recharge; g) Improperly managed stormwater runoff can increase the incidence of flooding and the level of floods which do occur, endangering property and human life; h) The economy of the Town of Morehead City, as well as the health and welfare of its citizens, is dependent upon the preservation of local beaches, clean navigable waterways and marinas, abundant fishing and shellfishing resources, and a healthy ecosystem that attracts visitors to the Town. Many future problems can be avoided or substantially mitigated if land is developed in accordance with sound stormwater runoff management practices. Sec. 3. Objectives. In order to protect, maintain, and enhance both the immediate and the long-term health, safety and general welfare of the citizens of the town, this ordinance has the following objectives: a) Minimize the transport of pollutants to area surface waters; b) Protect and maintain natural salinity levels in estuarine areas; c) Minimize erosion and sedimentation; d) Prevent damage to wetlands; e) Prevent damage from flooding, while recognizing that natural fluctuations in water levels are beneficial; f) Protect, restore, and maintain the habitat of fish and wildlife; g) Ensure the attainment of these objectives by requiring the approval and implementation of stormwater management plans for all activities that may have a significant adverse impact upon community waters and nearby properties.

Subdivide means to divide the ownership of a parcel of land, whether improved or unimproved, into two (2) or more contiguous lots or parcels of land, whether by reference to a plat, by metes and bounds or otherwise, or, if the establishment of a new street, easement, or right-of-way is involved, any division of a parcel of land. Vegetation means all plant growth, especially, but not limited to, trees, shrubs, vines, ferns, mosses and grasses. Draft SWM Ordnance 4 'Town of Morehead City Waters or community of waters means any and all water on or beneath the surface of the ground. It includes the water in any watercourse, water body or drainage system. It also includes diffused surface water and water percolating, standing or flowing beneath the surface of the ground, as well as coastal waters. Water body means any natural or artificial pond, lake, reservoir or other area which ordinarily or intermittently contains water and which has a discernible shoreline. Watercourse means any natural or artificial stream, river, creek, channel, ditch, canal, conduit, culvert, drain, waterway, gully, ravine, street, roadway, swale, or wash in which water flows in a definite direction, either continuously or intermittently, and which has a definite channel, bed or banks. Watershed means a drainage area or drainage basin contributing to the flow of water into a receiving body of water. Wetlands means those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs and similar areas. The following three (3) conditions are necessary to define a wetland area: (1) Over fifty (50) percent of the dominant vegetation must be plants which are typically adapted for life in saturated soil conditions (hydrophytes); and (2) The soil is saturated long enough during the growing season to develop anaerobic (without oxygen) conditions that favor the growth of hydrophytes (hydric soil); and (3) There is a presence of wetland hydrology (the water table is no lower than twelve (12) inches or there is a presence of hydrologic indicators which show that water saturates the plant root system over long periods during the growing season). Sec.5. Applicability. All development and redevelopment, including, but not limited to, all single-family and duplex residential dwellings and all commercial development, constructed within the town after the effective date of this ordinance must comply with the minimum stormwater control standards outlined in Section 6. Sec. 6. Storm Water Management Standards (a) Performance standards. The proposed development, development activity, or redevelopment shall be planned, designed, constructed, and maintained to meet each of the following standards: (1) Ensure that, after development or redevelopment, runoff from the site approximates the rate of flow, volume and timing of runoff that would have Draft SWM Ordnance Town of Morehead City occurred following the same rainfall under existing conditions and, to the extent practicable, the predevelopment conditions, unless runoff is discharged into an off -site drainage facility as provided in section 6(c) (2) Maintain the natural hydrodynamic characteristics of the watershed; (3) Protect and, to the extent feasible, restore the quality of surface waters; (4) Ensure that erosion- during and after development or redevelopment is minimized; (5) Protect the beneficial functioning of wetlands as areas for the natural storage of surface waters and the chemical reduction and assimilation of pollutants; (6) Prevent increased flooding and damage that may result from improper location, construction, and design of structures in areas which are presently subject to danger from flooding; (7) Otherwise further the objectives of this ordinance. (b) Design standards. To ensure attainment of the objectives of this ordinance and to ensure that performance standards will be met, the design, construction and maintenance of drainage systems shall be consistent with the following standards: (1) Channeling runoff directly into water bodies shall be strictly prohibited. Instead, runoff shall be routed through swales and other systems designed to increase time of concentration, decrease velocity, increase infiltration, allow suspended solids to settle, and remove pollutants. (2) The area of land disturbed by development shall be as small as practicable. Those areas, which are not to be disturbed, shall be protected by an adequate barrier from construction activity. Whenever possible, indigenous vegetation shall be retained and protected. Where this is not possible, suitable nature species shall be planted. (3) No grading, cutting or filling shall be commenced until erosion and sedimentation control devices have been installed between the disturbed area and water bodies, watercourses and wetlands. Clean sand shall be used for fill. The fines in the sand should be limited so that seepage and migration through it will facilitate normal drainage. The fill shall be placed so as not to interfere with the natural and normal flow of surface water nor in any way cause water to be diverted to adjacent property. Pipe culverts shall be installed under driveways to allow passage of water, if consistent with good design practices. (4) Land which has been cleared for development and upon which construction has not commenced shall be protected from erosion by appropriate techniques designed to revegetate the area within thirty (30) days (seeding, etc.). Draft SWM Ordinance Town of Morehead City (5) Sediment shall be retained on the site of the development (6) Wetlands and other waterbodies shall not be used as sediment traps during development. (7) Erosion and sedimentation facilities shall be maintained to insure that they continue to function properly. (8) Artificial watercourses shall be designed, considering soil type, so that the velocity of flow is low enough to prevent, or minimize to the maximum extent practicable, erosion. (9) Vegetated buffer strips shall be created or, where practicable, retained in their natural state along the banks of all watercourses, water bodies or wetlands. The width of the buffer shall be sufficient to prevent erosion, trap the sediment in overland runoff, provide access to the water body and allow for periodic flooding without damage to structures. (10) Intermittent watercourses, such as swales, will be vegetated. (11) Retention and detention ponds shall be used to retain and detain the increased and accelerated runoff which the development generates.
