In response to your two emails of March 12, 2003 please except the following:
Enclosed is a portion of the existing topo map for the project with the spot elevation
layer turned on. There is an inverted crown that channels stormwater from the
existing facility to a catch basin at the eastern property line.
2. The existing buildings are A - frame and their roofs sheet flow off to the asphalt
below.
3. A revised Page 1 and 2 of the Application is attached with the infiltration trench area
revised.
4. When recalculating the permanent pool volume I came up with an amount of 21,501
ft.3 1 have reduced the size of the forebay by 5 feet, which provides a forebay
volume of 20.3% of the permanent pool volume. Two (2) copies of revised plans
(Sheet 3 and 5 of 5) and Engineering Calculations Page 5 are attached. Also
attached is a revised page 1 of the Wet Detention Basin Supplement.

Dear Gordon:
Based on the existing contours shown for the western part of the existing development, it appears that
more runoff from the existing development may enter the detention pond than you show. Do you have
more detailed information regarding how the existing drainage works? The existing contour information
just isn't detailed enough to support the delineated pond drainage area. is there an inverted crown
between the buildings? Does the runoff sheetflow offsite under the wooden fence along the western
property line? Where are the roof drains for the existing buildings located?
The volume calculations (for pond or infiltration) must be based on the drainage area to the system, not
just the BUA. The revised calculations for the infiltration trench indicate that only the BUA was used to
determine the volume. Lucky for you, the DA equals the BUA in this case. Please be aware of this for
future projects.

The delineated drainage area for the infiltration trench is dimensioned

application only accounts for 4,900 sq. ft. Please correct and revise
page 2 of the application. Since page 2 is on the back of page 1,
you'll need to include page 1 on the resubmitted application.
Please provide a table of elevations, areas and volumes to support your

Dear Mr. Stainback:
The Wilmington Regional Office received a Stormwater Management Permit Application
for Jacksonville A -Storage Inn on October 22, 2003. A preliminary review of that information
has determined that the application is not complete. The following information is needed to
continue the stormwater review:
V 1. Please specify the wetland species to be planted on the 6:1 shelf in the pond.
/2. Please dimension the pond's permanent pool contour, buildings and parking.
3. Please delineate the drainage areas to the pond and infiltration trench, including
�( any existing areas that cannot be diverted. Please show in detail how the runoff
Q from the existing areas that is not part of the drainage area is diverted.
ll,/4. Please provide an original signed and dated infiltration trench supplement. The
one submitted is a photocopy.
15. Please provide inverts for the trench and pipe on the infiltration trench detail. The
infiltration trench should be laid at a flat grade. It might be helpful to add a side
view detail of the catch basin and infiltration trench to the plans to show how the
connection between the basin and the trench is to be made.
t/ 6. Please show the proposed swale over top of the infiltration trench on the detail.
7. Please specify the 1.5" orifice diameter on the outlet structure detail.
V 8. Please eithe Qaqddcurb to the southern edge of the proposed pavement to insure
that the r>_tned into the catch basins, and to prevent erosion of the pond
slope behind the basins, or relocate the basins away from the edge and create an
inverted crown in the rear pavement as was done for the pavement between the
buildings. Provide sufficient spot elevations or details to demonstrate this.
f/ 9. If the infiltration system is not designed with a bypass, it must be designed to hold
a larger volume. For this project, a 2" desig�storm s appropriate. If you do not
wish to provide additional storage, o a bypass from the catch basin
to a 30' vegetated filter.

r`2 �t+5 10 All bypasses from an infiltration system must pass through a vegetated filter. For
%\ Ae` this project, a 30' vegetated filter is required. This filter must be located wholly
2 within the property boundary. DOT road ditches do not qualify as a vegetated
filter. Please show and detail the required 30' vegetated filter on the plans, in
accordance with the enclosed sketch.
V 11.. The wet pond supplement reports that the temporary pool elevation is 7.5, but the
plans and calculations use 7.2. Please correct and revise.
2 12. Please provide the calculations for determining the permanent pool volume. A
` table of elevations, areas and volumes in the pond, beginning at the bottom is
most helpful in making this determination.
13. The overflow elevation for the trench system must be 1.5' above the bottom
elevation, or 17.1'. Please report 17.1 on the supplement as the storage elevation
and on the trench detail.
Please note that this request for additional information is in response to a preliminary
review. The requested information should be received by this Office prior to February 9, 2003,
or the application will be returned as incomplete. The return of a project will necessitate
resubmittal of all, required items, including the application fee.
If you need additional time to submit the information, please mail or fax your request for
a time extension to the Division at the address and fax number at the bottom of this letter. The
request must indicate the date by which you expect to submit the required information. The
Division is allowed 90 days from the receipt of a completed application to issue the permit.
The construction of any impervious surfaces, other than a construction entrance under an
approved Sedimentation Erosion Control Plan, is a violation of NCGS 143-215.1 and is subject
to enforcement action pursuant to NCGS 143-215.6A.
Please reference the State assigned project number on all correspondence. Any original
documents that need to be revised have been sent to the engineer or agent. All original
documents must be returned or new originals must be provided. Copies are not acceptable. If
you have any questions concerning this matter please feel free to call me at [phone].

Reference: Soils evaluation for stormwater for the A -Storage Inn site,
Jacksonville, North Carolina.
Dear Mr. McAdams,
On October 10, 2002, Land Management Group, Inc completed the soil characterization for a
infiltration system at the A -Storage Inn site, as you requested. The purpose of this investigation
was to provide stormwater infiltration for a small parking area. The most limiting soils
encountered were sandy clay loam textured soils with permeability rates of 1" to 2" per hour.
The seasonal high water table for this area is approximately 50". The Iocation for this boring was
chosen by your office, but additional borings along the proposed infiltration pipe revealed similar
soils. The following is the detailed profile description of the boring.
Please do not hesitate to contact me if you have any questions about this report.
Sincerely,
J. Tom Gulley
