plan for 109 Scarborough Lane
The existing site consists of a vacant, heavily vegetated 0.86 acre parcel of land located on
Scarborough Lane off of Duck Rd. (NC 12). The closest intersection to the parcel is
Scarborough Land and Duck Rd. approximately 640 ft. to the west.
The parcel's owner proposes to construct a sales and management/maintenance facility
consisting of one building, parking facilities and all associated infrastructure, including water,
wastewater, stormwater and electrical utilities.
The proposed stormwater management method to serve the facility will consist of three.(3) dry
Infiltration basins_that.will provide temporary runoff storage volumes in accordance with the
Town of Duck and NCDENR requirements.
The following narrative sections along with stormwater calculations located in the Appendix of
this narrative will detail the parameters of the stormwater management plan and demonstrate
compliance with the Town and State stormwater management requirements.
Summary of Existing Conditions
The subject parcel is a vacant 0.86 acre parcel of land located on Scarborough Lane in Duck,
NC. The existing parcel is heavily vegetated with trees and shrubs mostly around the perimeter
of the parcel with 0 to 45 percent slopes. Ground elevations on the parcel range from 34' to 6'
above mean high sea level (mhsl). The parcel previously had a single-family dwelling located
on it; however, the lot is vacant now due to the permitted demolition of the existing
improvements.
Summary of Proposed Conditions
As previously mentioned, the project proposes to construct a sales and
management/maintenance facility consisting of one building, parking facilities and all associated
infrastructure, including water, sewer, stormwater, and electrical utilities.
The overall project proposes to construct 117,9 68 sq tf . of impervious surfaces on and off of the
parcel. Stormwater management improvements will be needed to control the runoff from
proposed impervious surfaces. Runoff from all new impervious surfaces is proposed to be
collected and conveyed to the infiltration basins located throughout the site.
The following detail sections the stormwater management design parameters for the infiltration
basin by its respective Drainage Areas. See the Drainage Area Exhibit located in the Appendix

Stormwater Management Narrative
109 Scarborough Lane Maintenance Facility, Duck, NC
August 6, 2013
of this narrative for reference to the Drainage Area and the corresponding infiltration basin.
Drainage Area 1
Drainage Area 1 (DA1) is the smallest drainage area on this project and has a total area of
1,201 sq.ft. 100% of this area is proposed to be impervious improvements due to it being a
collection from the building roof area via roof drains. The drainage area can be expressed as
the perimeter of the northwest portion of the building roof including the overhang.
Stormwater draining from this Drainage Area will be conveyed to Infiltration Basin 1 near the
middle of the west side of the building.
Collection
Stormwater will be directed to the infiltration basin via sheet flow over the roof and into the roof
drain collection system that will convey the runoff into Infiltration Basin 1.
Treatment
e,
The infiltration basin bottom and side slopes shall be lined with 4 inches of #3 river rock stone
on top of a porous geotextile fabric. The runoff will undergo filtration of particulates and
pollutants by the rock within the basin. A secondary method of treatment is also available when
the stormwater runoff infiltrates into the subsurface. The soil particles between the basin bottom
and the seasonal high water table (SHWT) will offer additional filtration and/or absorption of
particulates and pollutants prior to reaching the water table.
Storage
Infiltration Basin 1 has been designed with above grade storage of 109 cf. The calculated
runoff generated by the 1.5" rainfall event over DA1 is 143 cf. The overflow from Infiltration
Basin 1 will be conveyed to Infiltration Basin 3 via sheet overflow into Infiltration Basin 3's
collection system. Infiltration Basin 3 is overdesigned to accommodate this extra storage. See
stormwater calculations located in the Appendix of this narrative for a detailed breakdown of
stormwater storage volumes.
Disposal
Disposal of runoff from Infiltration Basin 1 will occur via infiltration into the subsurface. Based
on the determined soil saturated hydraulic conductivity of 0.528 in./hr., the basin is calculated to
drawdown in 1.52 days.
Drainage Area 2
Drainage Area 2 (DA2) is the next smallest drainage area on this project and has a total area of
2,205 sq.ft. 100% of this area is proposed to be impervious improvements due to it being a
collection from the building roof area via roof drains (same as DA1). The drainage area can be
expressed as the perimeter of the southwest portion of the building roof including the overhang.
Stormwater draining from this Drainage Area will be conveyed to Infiltration Basin 2 near the
southwestern corner of the building.

Collection
Stormwater will be directed to the infiltration basin via sheet flow over the roof and into the roof
drain collection system that will convey the runoff into Infiltration Basin 2.
Treatment
The infiltration basin bottom and side slopes shall be lined with 4 inches of #3 river rock stone
on top of a porous geotextile fabric. The runoff will undergo filtration of particulates and
pollutants by the rock within the basin. A secondary method of treatment is also available when
the stormwater runoff infiltrates into the soil subsurface. The soil particles between the basin
bottom and the seasonal high water table (SHWT) will offer additional filtration and/or absorption
of particulates and pollutants prior to reaching the water table.
Storage
Infiltration Basin 2 has been designed with above grade storage of 247 cf. The calculated
runoff generated by the 1.5" rainfall event over DA1 is 262 cf. The overflow from Infiltration
Basin 2 will be conveyed to Infiltration Basin 3 via sheet overflow into Infiltration Basin 3's
collection system. Infiltration Basin 3 is overdesigned to accommodate this extra storage. See
stormwater calculations located in the Appendix of this narrative for a detailed breakdown of
stormwater storage volumes.
Disposal
Disposal of runoff from Infiltration Basin 2 will occur via infiltration into the subsurface. Based
on the determined soil saturated hydraulic conductivity of 0.528 in./hr., the basin is calculated to
drawdown in 1.89 days.
Drainage Area 3
Drainage Area 3 (DA3) is the largest drainage area on the project and has a total area of 20,289
sq.ft. and 14,580 sq.ft. (71.9%) of impervious improvements. Impervious surfaces consist of the
remainder of the building, driveway and parking areas on the parcel. This drainage area can be
expressed as the perimeter of the impervious site all the way to Scarborough Lane while also
encompassing Infiltration Basin 3 and removing DA1 and DA2. Areas outside this drainage
area had SCS method curve numbers of below 64; therefore, assuming to runoff from a 1.5"
storm.
Stormwater draining from impervious areas within DA3 will be conveyed to the infiltration basin
located near the southwest corner of the property.
Collection
Stormwater will be directed to the infiltration basin via sheet flow over the remaining rooftop and
pavement to the curb and gutter collection system that will convey the runoff to the two (2)
proposed catch basins and then to the infiltration basin by approximately 47 If. of 18" HDPe N-
12 CPP pipe and 13 If. of 18" RCP pipe.
Stormwater Management Narrative
109 Scarborough Lane Maintenance Facility, Duck, NC
August 6, 2013
Treatment
The infiltration basin bottom and side slopes will be grassed according to the general seeding
specifications. The runoff will undergo filtration of fine particulates and pollutants by the
vegetation within the basin. The filtration by vegetation is considered the primary method of
treatment. A secondary method of treatment is also available when the stormwater runoff
infiltrates into the subsurface. The soil particles between the basin bottom and the season high
water table (SHWT) will offer additional filtration and/or absorption of particulates and pollutants
prior to reaching the water table.
Storage
For NCDENR stormwater permitting requirements, Infiltration Basin 3 has been designed with
above grade storage in excess of the 1.5" rainfall event. The calculated runoff generated by the
1.5 rainfall event over DA3 is 1,768 cf. The remaining overflow from Basins 1 and 2 total to 48
cf. (34 cf. + 15 cf. = 48 cf.). The total storage required for the 1.5" rainfall event over DA3 and
overflow from basins 1 & 2 is 1816 cf. Infiltration Basin 3 has been designed with an above
ground storage capacity of 1,872 cf.
The entire site including all Drainage Areas and Infiltration Basins is required to have 2,172 cf
of storage with the 1.5" rainfall event. The above grade storage provided for the entire site is
2,228 cf. and is equivalent to the 1.54" rainfall event over all the drainage areas. See the
stormwater calculations located in the Appendix of this narrative for a detailed breakdown of
stormwater storage volumes.
Disposal
Disposal of runoff from the infiltration basin located in DA3 will occur via infiltration into the
subsurface. Based on the determined soil saturated hydraulic conductivity of 0.528 in/hr, the
basin is calculated to drawdown in 2.37 days.
Soils
Quible & Associates, P.C. performed on -site soil borings to verify soil type and determine
elevations of mean high groundwater. Information collected on site generally agrees with the
United States Department of Agriculture, Soil Conservation Service Soil Survey of Currituck
County, which maps the site as follows:
DwE — Dune land — Newhan complex, 2 to 40 percent slopes
FrD — Fripp fine sand, 2 to 30 percent slopes
Soil borings conducted indicate a season high water table (SHWT) of approximately 3.9 feet in
elevation. Based on the determined SHWT, the infiltrations basins have been designed with a
minimum bottom elevation of 6.0 feet as to maintain at least 2.0 feet of clear separation to the
SHWT.

Re: 109 Scarborough Lane, Duck NC
As discussed, I performed a falling head slug test at the above address in the general location of the
stormwater pond at an estimated elevation of 6.0 feet. Depth to Seasonal High Water Table is
estimated to be 25 inches below ground surface (bgs). "Free Water" was encountered at a depth of
approximately 32 inches bgs, which is in general accord with recent rainfall (lack of) at the time of the
boring.
A falling head slug test was performed using a Global Logger Transducer. Data from the test was
downloaded and used to perform a falling head slug test analysis (Agtesoly) for unconfined aquifers
with the Bouwer-Rice Method. Based on the analysis, saturated hydraulic conductivity in the area of
the stormwater pond can be expected to be approximately 7.3 a-4 feet per minute or 0.528 inches
per hour. Please view the attached curve matching graph and associated data for additional details.
