Please find the enclosed Stormwater Management resubmittal for the above referenced
project. Per your letter dated September 28, 2005, revisions were made. The revisions
and any comments are provided below. Also provided is the first page of the application
form with the correct mailing address for the owner per our phone conversation.
➢ Please include a soils report detailing infiltration rates and soil characteristics.
A soil boring log is attached with infiltration rates as given in the soils report for
Dare County and the rates used in the calculations.
➢ Please provide existing elevations (especially around basins).
The existing contour lines have been turned on in the site plan. Select spot
grades where available have also been shown to assist you in your review.
➢ Please provide a map of the boring locations.
The layer with the boring locations has been turned on. The borings are labeled
B-1 (within Basin 2, north of the US158 entrance), B-2 (within Basin 3), and B-3
(southern edge of Basin 1).
➢ Please provide a flow distribution mechanism in basin 1 to evenly distribute the
flow.
A level single row of landscape timbers has been provided within Basin 1 to
promote even distribution of the stormwater.
➢ The table in section 111 #6 of the application should include a breakdown of the
drainage areas giving you three different tables.
Drainage area breakdowns have been provided for Basins 1 thru 3.
➢ In order to do without a bypass please provide at least double the design volume
of storage within basin 2.
Basins 1 and 2 have a bypass, it is Basin 3 that does not. Double the design
volume has been provided within Basin 3. Going back to Basins 1 and 2,

bypassing is provided via DI #2. Di#2 has the lowest rim of the pipe system and
when the basins overflow, stormwater flows out of DI#2 and into the existing
drop -inlet within the northern right-of-way.
➢ Label and provide calculations for each of the three basins. Basin I and 2 need
to have separate calculations showing required volume, provided volume, and
drawdown. Basins should also have the same name on the calculations as on
the plan sheet.
Calculations have been provided for all three (3) basins. All the information
requested is included within the calculations and the Basin names are consistent
between the plans and calculations.
➢ Please note that stormwater runoff appears to be leaving the site through the
driveway to the right-of-way near basin 3 instead of entering the basin. Please
show that drainage outside of the right-of-way will go back to the basin.
A slotted drain has been added at the northeast driveway to prevent stormwater
from leaving the site.
➢ Please provide the surface area at the overflow on all three basins. Within
calculations, please provide a table for each basin with elevation and
corresponding surface areas and accumulated volumes.
Not being entirely sure of the desired format that you want, I have provided a
table at the bottom of each calculation sheet conveying the information
requested.
➢ Please provide a catch basin detail. The bottom elevation of the box should be
lower than the pipe invert to act as pretreatment.
A catch basin detail has been provided and the bottom of the basin has been
lowered to provide pretreatment.
➢ Please show a sediment removal benchmark for each basin on details.
The cleanout elevations for each of the three (3) basins are shown on the basin
cross -sections.
➢ Please note on plans that the bottom of the basin must have a four -inch layer of
sand or be densely vegetated.
Note 24 has been added stating that a 4-inch layer of sand must be provided in
each basin.

I.G. Holdings intends to construct a 13,192 square foot retail building with an 812
SF two -bedroom dwelling unit as well as parking for 72 vehicles on a 1.80-acre site at
the southeast corner of the intersection of U.S. 158 and Gull Street in Nags Head, NC.
The site slopes gently from the west to the east, with a low area in the middle, with
elevations ranging from 5.5 MSL to 8.7 MSL. The soils are highly permeable and the
seasonal groundwater table appears to be at approximately 3.0 MSL. The site will be
filled to accommodate the proposed building finished floor elevation of 11.0 feet MSL.
Two primary infiltration areas located along the perimeter of the property provide
stormwater management for the majority of the site. Stormwater will sheet flow across
concrete and turfstone pavement either directly into the infiltration areas or into curb
inlets and a closed collection system conveying the drainage into the infiltration areas.
The infiltration/retention areas are interconnected by the collection system in order to
function as a single primary drainage area. The top of storage elevation for both basins
is 7.2. Drop inlet #2 controls this storage elevation, allowing rainfall in excess of the
design to roll down curb along the northern entrance and into the Town's drainage
system via a nearby drop inlet. An additional infiltration area at the northwest corner of
the site provides stormwater management for a lower portion of pavement. A slotted
drain has been provided to prevent runoff from going offsite.
Soil borings were taken to estimate the depth to the water table in the vicinity of
the infiltration areas and to view soil characteristics. The results of these borings can be
found in the attached soil boring table. The depth to the water table determined through
these borings was between 30" to greater than 60" below existing grades. The soils in
the USDA Soil Survey for Dare County are described as Corolla Fine Sand (CoB) and
Newhan-Urban land complex (NuC). The borings were very similar with borings B-1
and B-3 appearing to reflect the characteristics of the NuC soil and B-2 reflecting those
of the CoB soil.
Infiltration basin 1 and 2 provide enough volume to contain approximately 2-
inches of rainfall on the site. Infiltration Basin 3 is designed to retain 3-inches. When
considering infiltration within the basins, over 5 inches of stormwater is managed
throughout the site. Relatively low infiltration rates have been assumed for calculation
purposes. Attached is the grading plan including the stormwater management features,
calculations and soil borings for the site. \\\,1Mt;c'/J/

Dear Mr. Golasa:
This office received a Coastal Stormwater permit application and plans for the subject
project on July 22, 2005. A preliminary revieik of your project indicates that before a State
Stormwater permit can be issued the following additional information is needed.
➢ Please include a soils report detailing infiltration rates and soil characteristics.
➢ Please provide existing elevations (especially around basins).

Dear Mr. Moore:
Please find the enclosed Stormwater Management submittal for the above referenced
site. The project is a redevelopment and the owner intends to construct a 13,192 SF
retail building.
The existing site currently has minimal stormwater management. We are proposing to
manage stormwater through three (3) infiltration basins. The site has an overflow route
that is tied by swales to the Town of Nags Head storm drainage system.
Enclosed with this submittal are the Grading and Drainage Plans, applicable application
forms, fee, and supporting data and calculations for'this work. Please do not hesitate to
call me if you have any comments or questions regarding this project.

The following revisions have been made: the drainage area for each basin has been
shown on the plan, the boundaries have been dimensioned, drainage breaks in the
driveways have been shown, a note has been added that the roof drainage will be
directed to the rear, collected by gutters and downspouts and conveyed to Curb Inlet #1
and Catch Basin #2, both part of Basin #1, a note has been added that no wetlands
exist, and cross sections for each basin have been shown. Flow arrows have been
added to assist you in your review.
