In addition to my previous email, attached, please also provide the following
information:
The proposed emergency spillway will drain into a previously permitted curb outlet
swale for the Winds Ridge subdivision. No other drainage may enter that swale
without first modifying the low density application. We are requesting via
separate letter, that Martin Sorenson of Myrtle Grove Group, LLC, submit a modified
application to address the changes proposed under the winds Ridge plan submitted to
the NHC Planning Department on March 12, 2004. Perhaps, at the same time, Mr
Vincent can discuss moving the curb outlet swale and the spillway/vegetated filter
location for this infiltration basin with Mr. Sorenson.

The Division received a stormwater application for the subject project on February
24, 2004. The application is incomplete. Please provide the following information
prior to June 6, 2004, to continue the review:
1. Section 11I.1 of the application indicates that this will be a dry detention
system, the supplement is for an infiltration basin, and the calculations are for a
wet detention pond. Which system will be used at this site?
a. If it's truly infiltration, as the supplement and plans suggest, please add
a cross-section detail of the basin labeling the elevations and the 3:1 slope
requirement.
b. Additionally, please add an offline bypass mechanism, or provide storage for
3" of runoff.
2. Provide a 50, vegetated filter for all overflows from the infiltration basin.
Label the location on the plans, and provide a detail showing elevations and
grading for the filter.
3. Delineate the 2.43 acre drainage area.
4. Provide sealed infiltration calculations.

In response to your email correspondence regarding the above referenced project,
I have enclosed the following:
1. Updated site plan showing a revised location for the emergency spillway
and a drainage delineation map.
2. Updated detail sheet including a cross-section detail of the infiltration
basin.
I Sealed infiltration calculations.
4. 10-year and 25-year routing calculations to show that post -construction
runoff is lower than pre -construction runoff.
5. An updated page 2 of the stormwater application stating that the project
will be treated with an infiltration basin.
6. A copy of the soils report.
7. An updated stormwater narrative.
Please review for approval and contact us with any questions or comments.
Thank you.
Sincerely,

Stormwater Narrative
Dollar General — Winds Ridge
New Hanover County, NC
TE03114
Dollar General — Winds Ridge is a 1.35-acre existing vacant tract proposed for a commercial
shopping center. Impervious areas include 13,400 SF of building, 3,350 SF of sidewalk and
14,820 SF of asphalt, creating a total lot impervious area of 32,070 SF. The drainage basin also
includes a 1.08-acre vacant tract to be developed in the future with an estimated 32,000 SF of
impervious area.
The total drainage basin area will be 2.43 acres with 64,070 SF of impervious area. The total
percent impervious is 60.4%.
The project will be treated with an infiltration basin. The infiltration pond will be designed to
meet the State's 3" and the County's 25-year pre -post requirement. Outflow from the pond
drains to Everetts Creek, classification SA.

Linda:
Regarding the outfall location of the infiltration pond, we propose to
move the emergency spillway location so that it drains into the swale over
100, from the roadway flume. Currently the site drains to this area and our
design will actually lower the outfall on a 10 or 25-year storm.
Additionally, the pond is capable of storing 3" of runoff and this is not
counting infiltration.
If this is acceptable to you, I will forward drawings & calculations to
support our position.

An infiltration test for the development of The Winding River Business Center located on
Carolina Beach Road in Wilmington, North Carolina has recently been conducted.
Field Investigations
An investigation of the subsurface soil and ground water conditions within the proposed
storm water infiltration location indicated on the provided sketch was recently
conducted. The purpose of the investigation was to determine the suitability of the in -
place sails for the infiltration of storm water runoff. We investigated the subsurface soil
and ground water conditions by drilling a hand auger boring to depths of approximately
five feet below the existing ground surface at the approximate location indicated.
Subsurface soils were classified by depth. The attached Site Soil Evaluation form
provides a summary of the subsurface conditions encountered at the auger boring
location
Our field classifications test results indicate that the subsurface soils consisted of
relatively drainable stratas of fine to medium grained sands to the depths explored.

Infiltration Evaluation
Winding River Business Center
Wilmington, North Carolina
Although groundwater was not actually encountered to the depths explored. A thin strata
of cemented silty sands (hard pan) was encountered at a relatively shallow depth. This
thin strata will create a perrbed groundwater condition of seasonal rainfall. The seasonal
high groundwater condition was encountered at a depth of seven feet from a test pit study
conducted by others.
We also conducted an infiltration test near the hand auger boring location to estimate
infiltration rates for the subsurface soils. The infiltration test was conducted at a depth of
48 inches at the suspected depth of the proposed retention pond. The testing was
performed within the upper stratum of moderately-drainable fine to medium sands. The
results of this test arc summarized on the Site Soil Evaluation Form and are also listed
below.
The infiltration test was performed at a deptb of approximately 48 inches below surface
grade and indicated on infiltration rate of 0.19 inch per minute.
If you have any questions please do not hesitate to tail'.
