Stormwater Management Plan Narrative
Maple Industrial Complex
November 7. 2002
General
The following narrative will detail the proposed stormwater management plan for the proposed Maple Industrial
Complex and Airport Expansion.
The Maple Industrial Complex is located on County -owned lands to the cast of the Currituck Maple Airport (at the
end of SR 1379, approx. 8/10 ofa mile north of the intersection of SR 1379 and U.S. 158). As per state regulations,
a high density permit will be pursued and will encompass existing and future construction up to complete build -out
of the development. The proposed development will consist of development of a portion of the County -owned
lands to the east of the present-day airplane hangars as an industrial park and county facilities. An addition to the
airport facilities consisting of a new tertninal, associated parking, and additional airplane parking / loading area will
also be part of the total development proposed within the project are —a/ drainage -area. The land proposed to be
developed is centrally located within the county owned -lands and is generally bordered to.the north, east, and south
by undeveloped lands. To the west, the project is bounded by the Currituck Maple Airport Airstrip -and SR 1246
(Maple Road). The proposed stormwater management method will consist of-a'wet pond (existing, man-made) with
adequate storage capacity and sizing to provide stornowater management for the runoff generated by a one -inch
storm across the fully devclopc2`site.at complete build -out. The following narrative will summarize the parameters
of this design which will illustrate an eff&ctive stormwater management system.
-1
Summary of Existing Conditions
The project area consists of a sub -area of County owned lands at Currituck Maple Airport. The project area is
contained completely within the drainage area, and so for the purposes of this analysis,.the project area is considerd
to be the drainage area. The property is currently partially developed as an airport with airstrip, hangars, airplane
parking / staging area, a small amount of parking, access road, County park, and County fueling area. There are
also existing gravel drives accessing the areas of the property which are to be developed in the future as an
industrial park. Existing stormwater management consists of gassed swale conveyance of runoff to two
interconnected wet detention basins (which are grossly oversized for the current runoff received).
Summary of Proposed Conditions
An analysis of the existing wet detention basins show that they are of adequate size and capacity to provide
stormwater management for the project area at complete project build -out (80% coverage within industrial park and
40% coverage within county facilities and airport). Project conditions allow conveyance of runoff via open grassed
swales, and so the proposed stormwater management method is in -line with the existing method; open grassed swale
conveyance to wet detention basins. Runoff from all newly developed areas will be conveyed into the northernmost
basin, providing a forebay - mainbay basin layout.
Stormwater Collection, Treatment, Storage and Disposal
Collection
The stormwater runoff will be collected and directed via site grading, and then conveyed via a network of open
grassed swales to the existing we( detention basin (forebay basin). Stormwater piping is restrained to the bare
minimum required to convey flows under roads and travel aisles.
Treatment
Runoff from paved areas will sheet flow to the pavement edge where it is directed via site grading to grassed swales.
Long runs of grassed swales will deliver runoff from outlying portions of the drainage area and substantial treatment
and disposal will occur in these swales as runoff is being conveyed. Large particulates and debris will accumulate
along the road shoulder and at discharge points into the swale system. The swales will be grassed according to the
general seeding specifications and maintained according to the operation and maintenance plan. The runoff will
undergo filtration of fine particulates and pollutants by the vegetation within the swales. Additional treatment is
also available when the stormwater runoff infiltrates into the subsurface. When the water passes through the void
spaces between the particles of soil material particulates and pollutants that have a particle or grain size larger than
the void size will be filtered out. In addition some pollutants will adsorb to the surface of the soil particles. The
benefit of this adsorption will prevent the pollutants from reaching the water table and in some nutrient and microbe
rich areas existing within the subsurface the pollutants will be consumed as food and undergo a natural
biodegradation.
The wet pond system will temporarily store stormwater above permanent pond. The season 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. When stormwater runoff begins to accumulate
above the permanent pool elevation the pond level will increase and the existing vegetation on the 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 will offer an
extensive storage time allowing for maximum settling. The surface area to drainage area (SAMA) 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.
S to ragg
The proposed stormwater wet detention basin will provide storage of the 1 inch design storm in temporary storage
above the permanent pool elevation.
The storage available in the wet detention basin is measured from the permanent pool elevation of 8.4'MSL to the
overflow weir elevation of 8.85' MSL (0.45' storage depth). As shown in the stormwater calculations (see
Appendix), the overall drainage area to the wet detention basin consists of 167 acres (7,274,329 sf). The design
storm of I " of rainfall, collected for this entire drainage area, results in a required storage of 246,900 cf and the wet
detention basin, as designed, provides for this temporary storage. It should be noted that the temporary storage
required for a I " rainfall event does not take into account the amount of runoff which will infiltrate into the
subsurface within the long -run swales prior to discharge into the wet detention basins, and therefore, the storage
provided will probably substantially exceed what is required for containment of the first inch of runoff.
DiWosal
As discussed in previous sections the majority of stormwater runoff entering this management system will be
infiltrated, therefore infiltration will be the primary source of disposal. At such time that the capacity were to be
exceeded the system will then overflow into the adjacent drainage swale via an overflow structure.
Soils
Quible & Associates visited the site to perform on -site soil borings to verify soil type and determine elevation of'
mean high groundwater. Seasonal high groundwater indicators within the existing pond were found at an elevation
of +/- 8.4 feet.
Information collected on site indicates that the soils found throughout this site are composed primarily of fine
loamy sands. These moderately well drained soil types will have a moderate to moderately rapid permeability,
These findings generally correlate with the description mapped and discussed in the United States Department of
Agriculture, Soil Conservation Service, Soil Survey of Dare County, North Carolina, which map the soil for this site
as follows:
CnA - Conetoe loamy sand, Permeability is moderately rapid.
Mu - Mundcn loamy sand, Permeability is moderate.
Pt - Portsmouth fine sandy loam, Permeability is moderate.
Ds - Dragston loamy fine sand, Permeability is moderately rapid.
AaA - Altavista fine sandy loam, Permeability is moderate.
StA - State fine sandy loam, Permeability is moderate.
Infiltration rates typical for these soils are generally in the range of 2-6 in/hr. A photocopied soils map with site
location has been included within this narrative.
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 the prescribed I inch of stormwater runoff
generated by all surfaces, pervious and impervious (up to complete build -out of the drainage area) located on this
site by making use of two existing wet ponds an conjunction with long -run vegetated infiltration swales. 'Me
proposed system will offer preliminary, primary and secondary methods of treatment as well as an alternate method
of disposal should the capacity be exceeded. The soils on site generally have infiltration rates in the range of2 to 6
inches per hour, conditions adequate for an infiltration system. This proposed design will more than adequately
serve the stormwater management requirements of this site.

When using the Division SAIDA tables, the correct SAIDA ratio for permanent pool sizing should be computed based upon the
actual impervious % and permanent pool depth. Linear interpolation should be employed to determine the correct value for non-
standard table entries.
2 In the 20 coastal counties. the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide
90% TSS removal. 'Me NCDENR BN4P manual provides design tables for both 85% TSS removal and 90% TSS removal.

111. WET DETENTION BASIN OPERATION AND MAINTENANCE AGREEMENT
The wet detention basin system is defined as the wet detention basin, pretreatment including forebays and the
vegetated filter if one is provided.
This system (check one) 0 does 0 does not incorporate a vegetated filter at the outlet.
This system (check one) 0 does 0 does not incorporate pretreatment other than a forebay.
FormSWU-102 Rev3.99 Page 2 of 4
Maintenance activities shall be performed as follows:
After every significant runoff producing rainfall event and at least monthly:
a. Inspect the wet detention basin system for sediment accumulation, erosion, trash accumulation,
vegetated cover, and general condition.
b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs
within 2 to 5 days as designed.
2. Repair eroded areas immediately, re -seed as necessary to maintain good vegetative cover, mow vegetative
cover to maintain a maximum height of six inches, and remove trash as needed.
3. Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to
maintain proper functioning.
4. Remove accumulated sediment from the wet detention basin system serni-annually or when depth is
reduced to 75% of the original design depth (see diagram below). Removed sediment shall be disposed
of in an appropriate manner and shall be handled in a manner that will not adversely impact water quality
(i.e. stockpiling near a wet detention basin or stream, etc.).
The measuring device used to determine the sediment elevation shall be such that it will give an accurate
depth reading and not readily penetrate into accumulated sediments.

Remove cattails and other indigenous wetland plants when they cover 50% of the basin surface. These
plants shall be encouraged to grow along the vegetated shelf and forebay berm.
6. If the basin must be drained for an emergency or to perform maintenance, the flushing of sediment
through the emergency drain shall be minimized to the maximum extent practical.
