Will you please advise?

Linda,
I have looked at the comments you sent on April 27th and have made the
appropriate changes.
The orifice size and the provided volume were miscalculated, and have been
corrected. Due to the error in calculations, the forebay had to be resized
and shrunk down 2416 cu. Ft. the orifice was reworked and found to be 2in
in diameter.
The discrepancy in the Windsor Park SW8 041041 built upon area and the
Bridgeport Townhomes SW8 050807 offsite built upon area was due to a
rounding error on my part, converting from acres to square feet. The
correct built upon area is 152,333 sq. ft. I have looked at the
calculations for this pond and it was designed for the 152,333 sq. ft. total
and therefore with the additional, square footage the pond design will not
change at all.
I am ready to send to you the corrected onsite pond calculations for SW8
050807, along with page 1 of the wet detention basin supplement, and the
updated Stormwater and Erosion Control Plan with the new pond design on it.
As for Windsor Park SW8 041041, I am assuming that just the Stormwater
Permit built upon area needs to changed, and you can just mark that yourself
if you wish.
I have just been told you need an updated Stormwater and Erosion Control
Plan for SW8 041041 with the offsite drainage area shown. I will update
that send it to you with Bridgeport Townhomes documents if that is ok.
Please let me know if I do need to send any other documents to you, so I can
get everything to you at one time.
Thank you,

I have reviewed the additional information for this project, submitted
on March 28, 2006, and have the following comments:
1. The average head used to calculate the orifice size is much'too
large. I think there was some kind of error in calculating this value.
It should be around 0.33 feet. The 1" orifice size is too small.
2. The calculations indicate that the volume provided in the pond is
26,776 cubic feet, however, that is not correct, based on the areas and
1 of 2 5/3/2006 4:43 PM

RE: Bridgeport Townhomes SW8 050807
f incremental volumes in the calculations.
3. The application indicates that the built -upon area associated with
that portion of this project that drains offsite to the pond permitted
under SW8 041041, is 152,333 sq. ft., however, the 041041 permit
allocates only 152,025 sq. ft. for this project. It is a relatively
minor amount, but if 152,333 is the correct total, the 041041 permit
will need to reflect this total. I have drafted the 041041 permit, but
not yet issued it, so you can make that change without waiting for
another modification.
Please submit the requested information by May 27, 2005.

Request for Additional Information: 4/27/06
Dear Ms, Lewis:
Inclosed 15 the re5por5e to your request for additional information or the above referenced project:
Item # I : There was an error in calculating the size of the orifice and it has been corrected. With
the new corrected pond calculations the new orifice size should be 2 inches in diameter.
Item #2: The calculations for the volume provided m the pond were incorrect as you stated.
These calculations have been updated and corrected, and therefore the forebay was
re512ed. The new pond calculations have been attached.
Item #3: The discrepancies in built -upon area were created by a rounding error; the correct total
is 152,333 square feet. As we discussed in our email correspondence on May 3.
2006, all that needs to be corrected is the Windsor Park 5W8 04 104 I off5ite built -
upon drainage area. The pond was designed for the 152.333 Square feet of built -upon
area and therefore all pond de5ign5 for Wlnd5or Park Should still be valid.
Enclosed, p4ease find the updated 5tormwater and Er051011 Control Plan, Page I of the Wet Detention
Basin Supplement for the current onsite pond, and the updated West fond Calculations for 6ridgeport
Townhomes.
Please let our office know if any further information 15 required for approval of this 5tormwater design.

Re6jue5t for Additional Information: I O/06/05 C,�!Vit;D
Dear M5. Lewis: NOV 0 2 Z005
Since our previous transmittal, it has become apparent that the starmwater plan=s-pond-loc ons-would
remove the natural buffer between the proposed residential development and"the e sting=industraak=L�
manufacturing areas acro55 Trade Street
As adequate buffering 15 essential to this project's success, we have modified the 5tormwater
management plan and the project's site plan to allow incorporation of that exi5ting vegetation in to our
overall design.
For this reason, the two ponds along Trade Street are no longer a part of this project. In their place, we
will utilize offsite discharge to an CX15ting pond on the adjacent subdivislon (permit 5W8 04 104 1 :
modification submitted to Rhonda Halls attention concurrently with this re5pon5e) and an onsite pond
located where Park #8 and Building #9 were formerly shown.
Because of this design change some of the information required by your letter 15 no longer applicable. In
regards to our current Submittal, however, each comment has been evaluated, answered or reflected on
the plan to the best of our ability. Here are the responses to the itemized comments:
Item # I : The vegetated shelf has been designed to the slope of I O: I and aU details have been
corrected.
Item #2: The wetland species to be planted on the shelf can be found with the details on the
drawing 5WEC I .
Item #3: The drainage area for each pond has been shown on the drawing.
Item #4: The vicinity map has been updated.
Item #5: The built upon areas have been updated to show both square footage and acreage on
page 2 of the application
Item #6: All built upon areas and sidewalks have been accounted for in the permit appllcat�on
package.
Item #7: With the change in the overall 5tormwater management plan, this comment is no longer
specific to the new design. Please note, however, that the onsite pond has beer
designed with a I " orifice and a temporary pool elevation of 68.7'.

Dear Mr. Stephens:
The Wilmington Regional Office received previously requested information regarding the
pending Stormwater Management Permit Application for Bridgeport Townhomes on November
2, 2005, A preliminary review of that information has determined that the application is not
complete. The following information is needed to continue the stormwater review:
1. Since two different developments presumably with different governing HOA's, will be
sharing the use of one of the wet ponds in Windsor Park, please provide a signed
agreement between the two developments for the shared maintenance
responsibilities for that pond.
2. Please specify the pond number in Windsor that will be accepting a portion of this
runoff, on the offsite supplement form. Additionally, please specify the amount of
allocated built -upon area in square feet. .
3. None of the ponds currently permitted under SW8 041041 has any offsite drainage
areas accounted for. A permit modification to SW8 041041 must be submitted and
issued prior to issuing this permit. There is no record of receiving a permit
modification for Windsor Park under. SW8 041041 in November 2005. Rhonda
remembers receiving a letter from Comer Lyons, but there was no check and no
application package provided. She called Comer on November 21, 2005, to discuss
the matter. The application and fee submitted for Bridgeport cannot be used to
process a modification for another permit. A modification to the Windsor Park permit

Bridgeport Townhomes
Brunswick County
ChO
Dear Mr -Stephens:
The Wilmington Regional Office received a Stormwater Management Permit Application for
Bridgeport Townhomes on August 1, 2005. A preliminary review of that information has
determined that the application is not complete. The following information is needed to
continue the stormwater review:
1. The pond section detail indicates that the vegetated shelf is at a slope of 6:1, but
there is a note below the plan view of both ponds that indicates the vegetated shelf
is sloped -at 10.1. Please correct one or the other and specify the 10' width and the
correct slope and elevations for the shelf on the pond section detail.
2. Please specify the type of wetland species to be planted on the shelf.
3. Please delineate the drainage area to each pond.
4. Please add the nearest intersection of two major roads to the vicinity map, and the
name of and distance to the nearest town or city. A major road is any 1, 2 or 3 digit
NC, US or interstate highway.
5. Please report all built -upon areas in square feet on page 2 of the application.
6. A preliminary check of the built -upon area numbers reported indicates that the
buildings alone are 3.02 acres of built -upon area, but the application only accounts
for 2.94 acres. Additionally, the application does not appear to account for the 3.5'
wide sidewalk that runs on both sides of the street and around the cul-de-sac. This
area is almost 6,700 square feet.
7. The temporary pool elevation (TPE) for Pond #1 has been reported as 64.9,
however, the temporary pool volume (TPV) has been reported based on elevation
66. Since this pond does not have an outlet at the 1" storage elevation of 64.9,
please note that the TPE has been changed to 66. In order to report the TPE at
64.9, you would need to provide an outlet at 64.9, and report the TPV based on the
volume between 64 and 64.9.

8. Please base the orifice calculation on the 1" volume, with an average
driving head based on the difference between the temporary -pool
elevation and the centerline elevation of the chosen orifice.
9. Please dimension each line and arc that makes up the permanent pool
contour in each pond.
10. How will people access the buildings from the parking lots without
sidewalks? Any surface used to walk on or drive on, which is subject to
compaction, is considered to be an impervious surface.
11. Please provide specific elevations for the high points, and provide
sufficient spot elevations for the project to demonstrate how the drainage
is getting into the pond.
12. Please add a note to the plans that all roof drainage must be directed into
the pond, and show the location of the roof drain collection piping or show
sufficient elevations and grading to demonstrate how the roof runoff will be
collected and drained to the pond.
13. The calculations indicate that Pond #1 is 4' deep, however, the chart
below the pond section detail and the supplement indicate that the pond is
5' deep. There is a note below the plan view of Pond #1 that says the'
pond bottom is elevation 60, however the section detail table and the
supplement both say the bottom is at 59. Please revise to specify one
consistent pond bottom elevation.
14. Please add a dimensioned detail for the split entrance road.
15. Please dimension Park 1 and Park 8 on the plans, as these are a different
size that the others.
16. The plans indicate that the scale is 1 "=100', but the dimensions noted are
for a 1 "=50' scale.
17. 1 am unable to check the pond design until the BUA discrepancies are
resolved and the drainage area delineation is provided. Please be aware
that the pond design will be checked upon receipt of those items, and
additional information may be required if there are any problems.
Please note that this request for additional information is in response to a, preliminary
review. The requested information should be received in this Office prior to November 6,
2005, 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

1. 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 ofsix 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 semi-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 as such that it will give an accurate
depth reading and not readily penetrate into accumulated sediments.
When the permanent pool depth reads 3.75 feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads 3.75 feet in the forebay, the sediment shall be removed.
