I have your letter of June 25, 1996 requesting additional information
on Stormmater Project No. 923108, Meadowbrook Subdivision.
The following information is given in accordance with the paragraphs
used in your letters
1. Dimensions on pond No. 3 now reflect the correct size.
2. Pond No. 1 is actually an irregular shaped pond which required
an accurate field survey to determine the area at permanent pool
level. however, the approximate dimensions have been shown and
the area scales the proper amount. Field survey information is
available if you rased it.
3. It is my information from Margaret Grey with Landmark Organization
that you agreed to allow the installation of an 8 inch ductile iron
pipe from the outlet structure to the northeastern corner of the
pond with the location of the 1* inch drawdown pipe at this point.
This has been accomplished.
4. You will note that a chart has been prepared for Pond Data in
which the area of the pond at permanent pool level and at maximum
pool level is given.
5. The number of lots in Phase I is 17. The number of lots in Phase II
is 273. This makes a total of 290 lots in this subdivision, therefore,
no revised density calculations are required.
I hope this will provide sufficient information to allow you to approve
the changes in this subdivision.
Yours Very Tmay,

Subject: ADDITIONAL INFORMATION
Stormwater Project No. SW8 921108
Meadowbrook Subdivision
New Hanover County
The Wilmington Regional Office received a Stormwater Management Permit Application for
Meadowbrook Subdivision on June 6, 1996. A preliminary review of that information has determined that
the application is not complete. The following information is needed to continue the stormwater review:
The dimensions labelled for Pond 3 do not scale as shown. Please check.
2. According to the dimensions given for Pond 1, the surface area is only 4,500 square feet,
not 5,168 square feet as reported in the calculations. The plans must reflect the calculations
as to the surface areas. ie., if you say 5,168 sf is provided, the contours must scale at
5,168. Please check.
3. Please relocate the outlet structure for Pond 1. The incoming pipe from Section I will cause
short-circuiting of the runoff. The runoff from Section I was piped to the pond without
benefit of a permit review by this Office; the problem could have been identified and dealt
with had Landmark received a permit prior to constructing the ponds.
4. Please report in the calculations the surface area provided at the max pool elevation. As
stated to you in the past, it is highly unlikely that the surface areas and volumes provided
in the pond exactly match up with the calculated requirements. The general method of pond
design is to determine the required elements, then to delineate contours such that compliance
with the minimum required elements is demonstrated. Orifice sizing is based on the volume
actually provided in the pond. If the difference between what is required and what is
provided is substantial, then the orifice may be too small to handle the volume and problems
with compliance may result.

5. The plans show 17 lots in Phase I and 273 lots in Phase II, for a total of 290. Is this the
correct lot total? Please revise the 297 figure on the preliminary plans, and provide a
revised lot layout, if 290 is incorrect. Since the original Certification covered 280 lots in
Phase II, the 2,405 ft2 of built -upon area calculated for the original is still valid for this
modification. If the number of lots increases to more than 280 in Phase H, revised density
calculations and an amendment to the recorded deed restrictions will be necessary.
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 July 25, 1996, or the application will be
returned as incomplete. The return of a project will necessitate resubmittal of all required items, including
the application fee.

Dear.Mr. Andrews:
The Wilmington Regional Office received previously requested information for Meadowbrook
Subdivision on March 11, 1996. 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. There are still no details of the ponds' cross -sections or outlet structures on the plans. The
best thing to do with so many ponds is to create a new plan sheet with all four ponds on it
shown in contour with dimensions, outlet structure elevations, pool elevations, orifice size,
etc., listed in a table similar to the one on the preliminary plan.
2. Please label the locations of the swales and add a detail indicating the type of grass cover
and the 5:1 slope. At Court "J", a flume is still shown in addition to the pipe. The
preliminary plan does not show the catch basins and piping for the swale at Lot 187. The
calculations still show the calculations for the swale along lot 263, which has been deleted.
3. Please add a flume detail to the plans.
4.: Please label the pipe sizes, material, and slope on the preliminary plan.

Dear Ms. Lewiss
I have your letter of January 5, 1996 requesting additional information
on Stormwater Project No. 921108 , Meadowbrook Subdivision, Phase U.
As you know, the permit was originally issued for all stormwater to be
handled in swales. These swales proved to be deeper than the developer had
anticipated, and they decided to use ponds for the latter phases.
The original calculations for allowable impervious area.per lot were
based on a total of 280 lots. Although some lot numbers are higher than 280,
many lot numbers h+ave..bsen skipped, resulting in a final total of 274 lots.
This would allow a slightly higher number of sq. ft. of impervious surface
per lot than the 2.405 sq* fte originally calculated. However, since most
of these lots have been developed under the 2,405 sq. ft. limitation, I am
not using the higher number.
I am submitting maps showing the drainage area going to each pond. I found
that the ovals between lots 39 & 40 had been piped and carried into pond No. 1.
I have added this drainage area to pond No. 1, and with some adjustments to
the drainage structure, the pond size does not have to be changed.
I found that the drainage area for pond No 2 had also been increased
beyond my original calculations. This will require some minor adjustments
to the drainage structure, bat the pond size can remain as it is now.
Ponds 3 & 4 have been dig and the side slopes have been sodded, but the
drainage structures have not been installed. These will be installed at the
design elevations.
I am enclosing a new application form and a pond maintenance plan. It is
my understanding that the required fee of $385.00 has already been paid.
I hope this will provide the additional information requested.

Dear Mr. Andrews:
January 5, 1996
28406
Subject: ADDITIONAL INFORMATION
Stormwater Project No. 921108
Meadowbrook Phase Ii
New Hanover County
The Wilmington Regional Office received a Stormwater Management Permit Application for
Meadowbrook Phase II on December 13, 1995. 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. Please highlight the drainage area to each pond.
k
2. There are no pond details on these plans. I need specific contour information, permanent
pool elevations, storage pool elevations, outlet structures, pond dimensions, etc. before a
thorough review can proceed.
5 �3. Not all of the previously certified Phase 11 is included in this submittal. Will that part be
left alone and continue to use the approved grassed swales? Since Phase II of the subdivision
will be permitted as a whole, the submittal form must reflect the entire subdivision. The two
columns on the form can be used, one for the ponds and one for the curb and gutter. The
breakdown can be split up as well.
4. What are the surface areas provided at the permanent pool and storage pool elevations?
(01' 5. Pond 1 appears to be located within an area that is shown as 2 lots in the remaining Phase
N C:,7 H, and which has a 100' swale located on it. Are these two lots deleted from Phase II? If
5 I6A-5 yes, then that portion of Phase II must also be revised. The original Certification was for
2 280 lots. The revised plans indicate 285 lots. Please clarify. What about the swale? Will it
drain into the pond? Has the pond been designed to account for this?

✓7. Pond 2's SA/DA ratio is incorrect. The surface area is deficient. Please recheck.
v -8. Pond 4's permanent pool elevation of 35.4 must be raised to 35.6 in order to provide the
6' design depth.
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 5, 1996, or the application will
be returned as incomplete.
If you have any questions concerning this matter please feel free to call me at [phone].
