North Carolina s _ Ij► county of Duplin hirpberlyN.And Do MyCommissionb Tres 2=1 PROJECT DESCRIPTION Outer Banks Amusements Currituck County - North Carolina January 18, 2012 Outer Banks Amusements, owned by David M. Shields, is proposing to construct a centralized warehouse on a 2.6 acre site in Poplar Branch Township of Currituck County. The site is located east of US Highway 158 in the Currituck Industrial Park near Powells Point. It is currently vacant and is zoned LM (Light Manufacturing). Development will include the construction of one (1) building, required parking and driveways, grassed swales, septic field, the installation of required landscaping and the construction of a water service and other utilities to the building. Currently the industrial park has public water supply along existing streets with existing meters available for connection. The septic tank and septic field are located on the east side of the building. The site is part of the high density industrial park which provides for stormwater management in the form of a retention basin known as Stormwater Retention Area "A" (see Stormwater Permit SW7040604, dated May 19, 2005). The proposed building will contribute 10,500 sf of impervious area. The proposed parking and driveways will contribute 26,815 sf of gravel surface and 360 sf of concrete pavement (for ADA parking), and concrete sidewalks will contribute another 265 sf for a total of 37,940 sf of proposed impervious coverage. An allotment of 20,000 sf of impervious area has been included for future expansion, bringing the ultimate build -out impervious coverage to 57,940 sf which is 51.2% of the total tract. A small area of offsite coverage is created by the proposed driveway connection to the existing road. Drainage Area 1 encompasses the entire tract of 2.60 acres (113,128 sf) including all proposed on -site impervious areas. Runoff from Drainage Area 1 will be collected in grass lined swales with minimal necessary pipes that will route all runoff to the existing retention basin to the west. Outflow from the basin will be directed to an existing drainage ditch which runs north to Currituck Sound. Per the Stormwater Permit (SW7040604) and the Final Plat for Currituck Industrial Park, the allowable impervious coverage per lot in this subdivision is 65% of each lot's area. For Lot 10 the maximum allowable impervious coverage is approximately 73,530 sf. Therefore, ultimate impervious coverage (57, 940 sf) is well within this allowable value. The total disturbed area for this development will not exceed 2.6 acres. Limits of disturbance have been shown on the plans.

NORTH CAROLINA ENVIRONMENTAL MANAGEMENT COMMISSION Yr—Alan W . Klimek, P.E. Director Division of Water Quality By Authority of the Environmental Management Commission Permit Number SW7040604 Currituck County Industrial Park Stormwater Permit No. SW7040604 Designer's Certification I, , as a duly registered Professional Engineer in the State of North Carolina, having been authorized to observe (periodically/weekly/full time) the construction of the project, for (Proj ect) (Project Owner) hereby state that to the best of my abilities, due care and diligence was used in the observation of the project construction such that the construction was observed to be built within substantial compliance and intent of the approved plans and specifications. Signature Registration Number Date e. ► . .. A RECEIVED Stormwater Management Plan Narrative (Revised) Currituck Industrial Park APR 2 0 2005 May l l , 2004 Revised 7//05 DWQ_WARO General The following narrative will detail the proposed stormwater management system to serve proposed roadway and future lot built -upon area for the proposed Currituck Industrial Park Subdivision. A high density permit is being pursued for this project. The Currituck Industrial Park subdivision is located at the (east) end of Dr. Newbern Road (SR 1 l 1 6i), approximately 2000 feet east of the intersection of Dr. Newbern Road and U.S. 158. As per state regulations, a high density permit will be pursued. The proposed development will ultimately consist of building construction, paved drive -aisles and parking, concrete walks, and stormwater management improvements. The Currituck Industrial Park Subdivision is situated on 72.43 acres. The proposed stormwater management method will consist of grassed roadside conveyances linked to four separate wet basins with adequate storage to hold the runoff generated by a 1 " rainfall event. The following narrative will summarize the parameters of this design which will illustrate an effective stormwater management system in full compliance with all state regulations. Summary of Existing Conditions The Currituck Industrial Park subdivision is located at the (east) end of Dr. Newbern Road (SR 1 1 16), approximately 2000 feet east of the intersection of Dr. Newbern Road and U.S. 158 in Poplar Branch Township, Currituck County. The entire site is currently undeveloped and consists of approximately 85% farm field and 15% woodland. There are no discernable existing stormwater controls and the bulk of stormwater runoff is allowed to flow overland toward an outfall ditch which rings the site. Summary of Proposed Conditions Stormwater management improvements will be needed to control the runoff fi'om proposed impervious construction. The post -construction site will consist primarily of four drainage areas which drain separately to four wet basins located in the northwest, northeast, southeast, and southwest corners of the site. Runoff within each of these drainage areas will be collected in proposed roadside swales and conveyed to the respective wet basins. Each of the four Wet Basins is designed with adequate capacity to retain and treat the first inch of runoff from any given storm. The ponds are proposed to be "off-line" and basin overflow structures are located outside the main basins within the contributing conveyances providing a true "bypass" of excess flows. It should be noted that the total storage capacity of each of the proposed wet basins is considerably in excess of the temporary storage (I " runoff) required. This is due to the wet basins also providing short-term temporary storage above the state's requirements in order to satisfy a pre / post stormwater quantity requirement of Currituck County. Total temporary storage provided for each basin is in the 5 inch to 6 inch (runoff) range. Stormwater Collection, Treatment, Storage and Disposal Collection The stormwater runoff will be collected and directed via site grading, roadside swales, and V-swales to discharge to the wet detention ponds. Where necessary, swales will be interconnected via culverts. Treatment Runoff from paved areas will sheet now to roadside swales, which will then convey runoff to the wet detention basins. Large particulates and debris will accumulate along the roadside swales. Additional filtering will occur within the vegetation of the proposed roadside V-swales along with some infiltration (the flow path for a large portion of the proposed development will be very long providing a substantial opportunity for significant pre- treatment of runoff within the swales). The roadside v-swales will discharge to the pond forebays via ditch sections located near the bypass overflow structure at each pond. Once the runoff reaches the basins it will pass through a vegetated shelf on its way into the forebay area. This vegetated shelf will exist around the entire perimeter of the wet pond permanent pool. It shall be constructed at a 6: l slope and have a width of 6 feet around the entire permanent pool and the majority of the forebay area. This shelf is to be vegetated with the following native wetland species Typha augustifolia. Typha latifolia, Juncus roemerianus, Juncus effitsus and Baccharis halimifolia. The placement of the Typha augustifolia, Typha latifolia, Juncus roemerianus and Juncus eff tsus will be on 2 toot centers and Baccharis halimifolia on 5 foot centers. The Baccharis halimifolia shall be placed at the upper limit of the season high water table or on the dry side of the season high water table elevation in order to ensure the successful growth of this organism. In other words the root zone may be saturated and the organism can be subjected to occasional flooding but should not be submerged at all times. This vegetative shelf will act as the point of primary pollutant filtration and nutrient uptake. As the permanent pool undergoes seasonal fluctuations in water level and changes in depth due to precipitation, the stormwater runoff will pass repeatedly throughout the vegetation of the shelf actually assisting in bringing pollutants and nutrients in contact with the vegetated shelf as well as flushing this shelf periodically. This shelf will provide the same natural filtration function as naturally occurring wetland fringes and salt water marsh areas. The forebay is a pocket within the pond where the water enters a depression that allows for energy dissipation and sediment removal. As the runoff exits into the water surface the energy is diffused by the relatively large body of stationary water and therefore sediment removal occurs due to the particulates no longer being suspended by the turbulent flow. The forebay is surrounded by a forebay wall which consists of a submerged vegetated shelf existing approximately 1 foot below the permanent pool elevation. The elevation of the forebay wall is necessary to sustain the wetland plant species to be planted there. The species best suited for this area are those that can exist and flourish in water saturated soils such as the Needle Rushes (Jatttcus roemerianus, Juncus efj`usus) or the cattails (Typha augttstifolia, Typha latifolia). Once the vegetated forebay wall becomes well established with plant growth this wall will act as a strainer filtering the water prior to its entering the permanent pool. This vegetated forebay wall will act as a secondary method of filtration. The season mean high water table, based on observation of the existing on -site pond, occurs at an elevation of approximately 6.0 feet MSL. The season mean high water table will be considered the upper limit of the permanent pool. The storage provided by this system will exist from the permanent pool elevation to the top of the temporary pool elevation. The side walls of the temporary pool will be vegetated according to the general seeding specifications found in the enclosed plan set. When stormwater runoff begins to accumulate above the permanent pool elevation the pond level will increase and the vegetated side walls of the temporary pool will provide further filtration of pollutants and nutrient uptake. The extended duration time within the forebay will allow for particulate matter to settle to the bottom. In addition the entire pond, sized for greater than a l inch storm, will offer an extensive storage time allowing for maximum settling. The wet pond has been designed to accommodate 90% Total Suspended Solids (TSS) removal and storage. The surface area to drainage area (SAIDA) calculations reflecting the 90% TSS removal have been enclosed and can be found within the calculations section of the appendix. The wet pond as a stormwater management plan method will offer many excellent opportunities for stormwater treatment. .Storage This wet detention pond system will offer a portion of storage above the ground surface and a portion of storage within the void spaces available in the subsurface. Within Drainage Area 1, the runoff generated by a 1.0 inch storm will require 43,07.5 ft' of storage. 'Temporary storage provided in Wet Basin I is 119,558 cf. Within Drainage Area 2, the runoff generated by a 1.0 inch storm will require 32,386 ft' of storage. Temporary storage provided in Wet Basin 2 is 35,715 cf. Within Drainage Area 3, the runoff generated by a 1.0 inch storm will require 75,751 ft' of storage. Temporary storage provided in Wet Basin 3 is 179,491 cf, Within Drainage Area 4, the runoff generated by a 1.0 inch storm will require 31.815 ft3 of storage. Temporary storage provided in Wet Basin 4 is 261,909 cf, Additional unaccounted storage is available within the subsurface below the side slopes of the temporary storage down to the water table. Dis osal As discussed in previous sections a significant portion of stormwater runoff entering this management system will be infiltrated. The system has been designed with additional storage so that this site will have the capability to handle in excess of a 1.0 inch storm when such a weather event should occur. In addition to infiltration, flows in excess of the " storm are discharged to the site perimeter outfall ditch via outfall weir / orifice structures located at the bypass for each wet basin. Soils After numerous visits to the site by Quible & Associates staff the site indicates that a majority of the soils found throughout this site are composed of soils (CnA & To). These soil types will have moderately rapid and moderately slow (respectively) infiltration rates in naturally occurring soils. The following list are the soil types found at this project location. CnA - Conetoe loamy sand, 0 to 3 percent slopes. Permeability is moderately rapid with rates of 2 - 6 inches per hour. To - Tomotley fine sandy loam. Permeability is moderate to moderaely slow with rates of 2 to 6 inches per hour. The soil types found in the field correlate with the descriptions mapped and discussed in the United States Department of Agriculture, Soil Conservation Service, Soil Survey of Currituck County, North Carolina. A photocopied soils map with site location has been included within this narrative. A copy of the Soils Report by Environmental & Soil Service is also included in the appendix. Calculations A set of sample calculations can be found within appendix portion of this narrative. Conclusions The proposed stormwater management plan for this site will handle in excess of the 1.0 inches of stormwater runoff generated by all surfaces, pervious and impervious located on this site by incorporating roadside swales, V-swales, and four wet detention ponds. The proposed system will offer preliminary, primary and secondary methods of treatment as well as an alternate method of disposal should the capacity be exceeded. This proposed design should more than adequately serve the stormwater management requirements of this site. 1 JOB SINCE 1959 Quible SHEET SHEET NO. OF Quible & Associates, P.C.

Dc d S Neff Currituck County is proposing the construction of a water tower within the Currituck Industrial Park, which will require a modification to the above referenced permit. The water tower is to be constructed on a peninsula that extends in to the middle of wet basin 1. The wet basin will serve as the 100 foot water tower "fall zone" buffer. To accommodate the water tower site, the area of wet basin I has been expanded, thus preserving the originally approved pond volume. Attached, for your review, is a Stormwater Management Permit Modification Application, a copy of the revised plans for wet basin 1, revised calculations, and a revised narrative. The revisions to the plans, calculation, and narrative are specific only to the wet basin 1 reconfiguration. The new design complies with the existing permit's regulations. The proposed changes actually represent improvements to the previously submitted design as the basin's temporary storage volume is slightly larger and the flow path within the basin has been significantly increased. The following items are included and shall be considered part of this submittal package. • Review fee check for $420.00 • Two Copies of the Stormwater Management Permit Application Form • One Copy of the Wet Detention Basin Supplement • Stormwater Management Plan Narrative (Revised 4-4-05) • Calculations and Supporting Data • Two sets of plans (Sheets 1, 2, 15, and 16; Revised 1-14-05) f At your earliest convenience please review the enclosed plans and calculations for adherence to Your regulations.

Katherine C. Marchello, P.L.S. David S Neff On Behalf of Mr. Steve Farr, Quible & Associates, P.C. hereby submit for review and approval a North Carolina Division Of Water Quality, Stormwater Management Permit Application package for the Currituck Industrial Park. The Currituck County Industrial Park Subdivision currently consists of 72.43 acres of undeveloped land which is proposed to be subdivided into 50 Commercial lots for future development (65% maximum lot coverage within the proposed subdivision). The site is located at the (east) end of Dr. Newbern Road (SR 1116), approximately 2000 feet cast of the intersection of Dr. Newbem' Road and U.S. 158 in Currituck County. The project falls within the high density classification and the stormwater management plan will consist of grassy roadside infiltration swales, and a four wet detention basins. The enclosed narrative will explain in detail the stormwater management of this site. The following items are included and shall be considered part of this submittal package: I .

David S, Neff As per our phone conversation, we have relocated the outfall structures in the proposed wet basins in order to maximize travel time for stormwater within the basins. Basin #2 was also reconfigured to accommodate this change. Attached, for your review, please find two copies of revised plans (Sheets 1-5, 13 & 14) and revised calculations and narrative. The only revisions to the calculations and narrative are specific to the Basin 2 reconfiguration (the storage volume available within basin 2 actually increased with the reconfiguration. At your earliest convenience, please review the enclosed plans and calculations for adherence to your regulations.

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long -duration storms. The soils in the United States are assigned to four groups (A, B. C, and D) and three dual classes (AID, BID; and CID). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a stow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission, Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink -swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (AID, BID, or CID), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes.
