Dear Mr. Chapman:
On July 1, 2003, the Wilmington Regional Office received two plan revisions for
Stormwater Management Permit Number SW8 020637. The revisions include the
construction of Lots 1 and 2 of Progress Point. Lot 1 was allotted 30,693 ft`, and Lot 2
was allotted 64,164 ft2 under the modified Stormwater Management permit is?ued on
August 1, 2003. Lot 1 is proposing 29,998 ft and Lot 2 is proposing 58,583 ft . It has
been determined that a formal permit modification is not 'required for the proposed
changes. We are forwarding you an approved copy of each of the revised plans for your
files. Please add these to the original plan set.
Please be aware that all terms and conditions of the permit issued on August 1,
2003, remain in full force and effect. Please also understand that the approval of this
revision to the approved plans for the subject State Stormwater Permit is done on a
case -by -case basis. Any other changes to this project must be approved through this
Office prior to construction. If it is determined that the proposed revision will require a
modification to the permit, you will be notified.

Cary, NC 27513-2301
Dear Mr. Michot,
Upon reviewing the recent revision of the Progress Pont Master Storm
Water Plan we believe there are conflicts remaining that must be resolved
prior to issuing a storm water discharge permit.
Under the Tree Preservation Ordinance, Zoning section 19-171, a, 2,
all perimeter trees at least 8 inches in diameter (DBH) within a 20 ft strip
along the property line are protected and must be preserved to the
greatest extent practical. Under 19-171, a, 3 all hardwood trees at least 8
inches DBH and conifer trees at least 12 inches DBH are protected and
must be preserved to the greatest extent practical. The proposed
infiltration pond along Eastwood Road will require removal of 14 perimeter
trees and 12 other protected trees. Section 19-171, b, 1 stipulates that
these trees can only be removed if essential site improvements cannot be
elsewhere accommodated on the site. Since there are other alternatives
for storm water control the code requires preservation of these trees.
One alternative to the proposed plan is to use the existing natural
depression along Eastwood Road for infiltration and runoff control. This
practice is encouraged under the Wilmington Storm Water Management
Ordinance, Chapter 20, Article IV, Sec. 20-28, c, 1 which states that flow
attenuation by use of open vegetated swales and natural depressions is to
be considered first as the preferred method for on -site storm water
management. Storm water could be allowed to sheet flow from parking
areas into the existing depression as is currently occurring on the existing
CP&L building site. This type of design should reduce construction costs
since it requires less excavation and drainage structures. If the existing
depression has insufficient storage volume, reducing parking to the
minimum specified by the zoning code will reduce the storage volume
required and allow more design flexibility. Protected trees cannot be

removed for parking greater than the minimum specified by the zoning
code since it is not considered an essential site improvement under the
tree preservation ordinance.
Representatives of the developer present at the Wilmington Tree
Advisory Committee meeting of June 24, 2003 stated that some of the
protected trees would be preserved by grading around them and building
retaining walls. If this technique is to be used, please indicate the new
proposed grades along with the location and design of the retaining walls
on the plan. Note that for proper protection the tree canopies must be
delineated and left undisturbed per section 19-171, b, 3 of the zoning
code.
Please feel free to contact me at [phone] if you have any
questions or would like to discuss this matter.

Ken
I have copied Brian Michot on this email so that he can work on these
questions about the modified plans received on July 25, 2003.
I did not notice that the bypasses for the infiltration system were not
labeled on the plans. The structures CI-23 and CI-25 need to be labeled as
"Bypass Control Structure" and they need to reference the bypass control
structure detail on sheet C4.
The detail itself needs a little more information now that there are two
structures, instead of the one that was previously permitted. Please add
the 24" incoming drain line, the 30" outgoing line to the basin, and note
on the weir side that it drains to a 24" bypass to the vegetated filter.
Additioanlly, how will the bypass water from CI-23 be routed through CI-25
to the 24" bypass? You may need to add two separate details, one for each
structure.
Thanks, Linda

P 0. Box 33068
Raleigh, Worth Carclina
27636.3068
The proposed development is located at the southeast quadrant of the intersection of
Eastwood Road and Military Cutoff Road in Wilmington, NC.
The North Carolina Department of Environmental and Natural Resources
(NCDENR) and the City of Wilmington have previously approved this site for a
master stormwater permit. However, site plan revisions were required on the
northern side of the Progress Point property due to comments issued by the North
Carolina Department of Transportation (NCDOT). The proposed access drive
location on Eastwood Road was not approved by NCDOT and will only be allowed it
it is shifted to the northeastern comer of the property creating a greater separation
from the Military Cutoff and Eastwood Road intersection.
The new access point will require the previously approved stormwater pond "B" to
be moved to the west. The revisions will only take place north of the `Mixed -Use'
site and will not alter in any way the previously approved stormwater treatment
facility "A", storm sewer pipes, inlet locations, or impervious surface square footage
calculations for the Mixed -Use or Progress Energy sites.
Wet Detention Basin "A":
The required surface area using 90% TSS removal efficiency for the wet detention
basin based on the post -development drainage area of 7.71-acres with 3.91-acres
impervious was calculated to be 9,303-square feet. The required volume for the f-
inch design storm was calculated to be 14,173-cubic feet.
Surface area for the wet detention basin at the permanent pool was designed to be
9,794-square feet. Storage volume for the 1-inch rainfall was designed to be 14,251-
cubic feet at the elevation of 24.41. Based on the proposed volume of the 1-inch
storage and the 1 1/2-inch drawdown orifice set at the permanent pool elevation
(23.50), the 1-inch runoff drawdown time was calculated to be 3.3-days.
Infiltration Pond "B":
The required volume for the infiltration pond based on the post -development
drainage area of 4.64-acres with 3.20-acres impervious was calculated to be 1 t,297-
cubic feet. The volume proposed for the infiltration Pond "B" was calculated to be
11,329-cubic feet. Based on the proposed volume of the pond, the drawdown time
was calculated to be 8.60-hours.

Linda, thanks for working with me on this pond. Can you give me your feedback on the new design of the pond itself. We did not modify any piping (outflow
or inflow). The design of the pond for the 1" storm event down has not changed. We only took advantage of the corner for quantity and were able to lower the
top contour and shift the pond to save trees. We will also spade (move) some of the better trees from the bottom of the pond to the area outside the pond
limits.
The city believes we have met their request and intent of the code.
am in a bind on construction, we had plans to begin the end of next week and this is our only outstanding issue. Any help is appreciated. I feel we have
worked hard to make everyone happy and to save the trees on that stretch. Additionally, we will be planting additional trees in the that strip as a buffer.

Subject: RE: Progress Point Stormwater Pond Modification/ Tree Retention Plan
Phil/ Linda - In response to your requests to consider the use of the existing low area at the corner of Military Cutoff and Eastwood Road,
please find attached an exhibit that shows the stormwater pond contour modification to include that area as part of the designed
stormwater system at Progress Point. This exhibit also shows existing surveyed trees to be retained, removed or relocated.
POND MODIFICATION DESIGN SUMMARY
Scenario 1: Connect the 'designed pond" with the "existing low area" and provide both quality and quantity treatment, with the intent of
reducing the horizontal size of the designed pond by utilizing the additional volume of the existing low area.
We were unable to utilize the existing low area for stormwater qualit treatment because of this areas high existing elevation. The
"designed" pond area with bottom elevation of 24 has a bypass overflow elevation of 26.37, and cannot be lowered because of minimum
pipe slopes between the pond and the bypass structure. The lowest elevation of the existing low area is roughly 26, and averages more
26.5 or 27 for that area, thus being too high for stormwater quality treatment.

RE: Progress Point Stormwater Pond Modification/ Tree Retention Plan
Scenario 2: Utilize the existing tow area as a separate 'pond" for stormwater quality and quantity treatment, with the intent of reducing
the horizontal size of the designed pond.
The existing low area is not low enough relative to proposed site grades to provide a stormwater quality function and pond depth meeting
State requirements.
Scenario 3: Connect the existing low area to the designed pond and utilize the existing low area for stormwater quantity
treatment, reducing the vertical height of top of pond.
This is the scenario proposed on the attached sketch. The designed pond is connected to the existing low area, and that are is utilized
for holding 10 year+ stormwater volume, effectively reducing the height of the top of bank of the designed pond from 29 to 28, or even
27.5. This allows the designed pond to "shrink" in size by one contour, with the old top of bank 29 contour being eliminated and the 28
contour becoming new top of bank.
Incorporating the capacity of the existing low area allows for three new conditions favoring retainage of existing trees. First, trees that
would have been previously removed because of excessive fill can now be retained. Second, the additional volume of the existing low
area allows for the use of retaining walls within the designed pond around individual trees, to help preserve root structure. Third; the
designed pond can be moved so its 3:1 slope is now 11 feet from the ROW of Eastwood Road, allowing for additional existing tree
retention, area for spaded trees to be relocated to, and more area for new street yard/ SHOD yard plantings that may be required above
and beyond credit for trees to remain. In summary, a combination of revised grading, retaining walls, and spading/relocation of existing
trees is utilized to preserve as many existing trees as possible, incorporate the existing low area, and still provide the stormwater quality
and quantity functions required of this development by City and State guidelines.
We are confident Scenario 3 meets the interests and requirements of all parties involved. We appreciate the input you have been
provided, your time meeting in the field, and your offers of expedited review relative to final permitting from both the State and City. I
believe that all parties have benefited from this exercise.
will contact you both by phone to follow up with final submittal procedures and timeframes relative to permitting. Brian Michot of our
office will also be available to answer any of the more technical design issues relative to the scenarios listed above. His direct line is

Thank you for emailing page 3 of the application, however, it does not
contain what I requested. Please list the individual BUA limits for each
lot to page 3. The one you sent has only a total, 139,392, which is the
total only for the infiltration basin. The wet pond is also part of the
permit, so you need to include the lots and the BUA that will be
draining to the wet pond on the application, as well. The modified
application needs to show all of the previously approved facilities.

I was confused on the wet pond certification, I was thought we could certify both ponds when
they are completed. Is it required that the wet pond be certified prior to approving the
infiltration portion?

How was the off -site impervious area listed above derived?
The following italicized deed restrictions and protective covenants are required to be recorded for all
subdivisions, outparcels and future development prior to the sale of any lot. If lot sizes vary significantly, a table
listing each lot number, size and the allowable built -upon area for each lot must be provided as an attachment.
1. The following covenants are intended to ensure ongoing compliance with state stonmwater management permit number
SW8 020637 as issued by the Division of Water Quality. These covenants may not be changed or deleted without the
consent of the State.
2. No more than 139,392 square feet of any lot shall be covered by structures or impervious materials.
Impervious materials include asphalt, gravel, concrete, brick, stone, slate or similar material but do not include wood
decking or the water surface of swimming pools.
3. Swales shall not be filled in, piped, or altered except as necessary to provide driveway crossing.
4. Built -upon area in excess of the pennitted amount requires a state stormwater management permit modification prior to
construction.
5. All permitted runoff from outparcels or fitture development shall be directed into the permitted stormwater control
system. These connections to the stormwater control system shall be performed in a manner that maintains the integrity
and performance of the system as permitted.
By your signature below, you certify that the recorded deed restrictions and protective covenants for this project
shall include all the applicable items required above, that the covenants will be binding on all parties and persons
claiming under them, that they will run with the land, that the required covenants cannot be changed or deleted
without concurrence from the State, and that they will be recorded prior to the sale of any lot.

Progress Point Master Plan
New Hanover County
Dear Mr. Chapman:
The Wilmington Regional Office received a modified Stormwater Management
Permit Application for Progress Point Master Plan on February 20, 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:
1. The new location of the infiltration basin is a cause of concern. When we
were last there, the Soils Scientist had remarked that this location was
very low and wet, and the 2' separation from the seasonal high water table
may be difficult to achieve. Another investigation will need to be scheduled
with the Soils Scientist to investigate this new location.
2. Because the new infiltration pond is very long and narrow, a mechanism to
get the runoff evenly distributed across the enure bottom surface area is
required.
3. Please complete Section IV on page 3 of the application by listing each lot
and it's maximum allowed built -upon area. The built -upon area for Lots 1
and 2 has been increased from what was previously approved.
4. Please provide a coppyy of the recorded deed restrictions in accordance
with Condition No. 11.14 of the permit.
5. Please provide the designer's certification for the wet detention pond,
since construction on Lot 3 is underway.

Dear Mr. Chapman:
I reviewed the information submitted on June 2, 2003. While the
infiltration area spreader situation is resolved, two of the remaining
items listed in my April 29, 2003, request for additional information
have not been addressed. Please submit the following:
Page 3 of the application to include the individual maximum built -upon
area for each of the outparcels. It appeared from the calculations that
the BUA on Lots 1 and 2 had been increased.

CC: <[e-mail]>
Ms. Lewis,
Harlan forwarded me your e-mail response that you still require some method of distributing flow
through the proposed stormwater basin B, and that you are open to other solutions'to achieve this spread.
As we have mentioned previously, it is our opinion that a half -pipe spreader option is not practical, and
that the inlet configuration on page 82 of the BMP manual is not functional when applied to our pond
design, and that maintenance will be the key to adequate infiltration being maintained.
However, responding to your offer of submitting another solution for spreading the stormwater, we
propose the following solution for your consideration.
Add about 40-If of HDPE at the drop inlet at the west pond corner (between the 88-1f pipe and 239-If
pipe) and daylight into the west side of the pond. This would essentially create an approximate 50/50
distribution of the water into the pond, achieving a better spread ratio. The invert from the drop inlet for
this new pipe would be set lower and with better alignment, so that stormwater would primarily follow
into this new pipe and enter the pond when it reaches that corner. The 239-1f of 24" RCP that is currently
proposed would still remain as a bypass mechanism.
Thank you for your patience in dealing with this issue, and I look forward to your response.
Brian J. Michot, P.E.

Dear Ken:

Vincent Lewis, Bill Dunlop and I just got back from the site. The site
is suitable for the proposed infiltration system and does meet the
minimum design requirements. However, we would like to make an alternate
proposal, based on the observed site conditions, if possible.
The entire area between the existing parking lot and Eastwood Road is a
natural, bowl -shaped low area. There is very little needed to alter this
area in order to make it function as the stormwater runoff treatment
system. The space is currently serving that purpose for a large portion
of the existing site. Preservation of this natural area will provide a
stabilized site for the runoff that will not need to be seeded or
graded.
The problems I see are 1- the volume available in the natural area may
not be sufficient to meet the 1" minimum, and 2- the construction of Lot
3 is already underway and elevations of the piped collection system may
not be able to be revised at this late date so that the existing natural
area can be utilized. It is Bill and Vincent's concensus that the system
will work.

I realize that you are in a hurry for this permit, so if you can make

Have your engineers look at the feasibility and get back with me.
Thanks.

The proposed development is located at the southeast quadrant of the intersection of
Eastwood Road and Military Cutoff Road in Wilmington, NC.
The North Carolina Department of Environmental and Natural Resources
(NCDENR) and the City of Wilmington have previously approved this site for a
master stormwater permit. However, site plan revisions were required on the
northern side of the Progress Point property due to comments issued by the North
Carolina Department of Transportation (NCDOT). The proposed access drive
location on Eastwood Road was not approved by NCDOT and will only be allowed if
it is shifted to the northeastern corner of the property creating a greater separation
from the Military Cutoff and Eastwood Road intersection.
The new access point will require the previously approved stormwater pond "B" to
be moved to the west. The revisions will only take place north of the `Mixed -Use'
site and will not alter in any way the previously approved stormwater treatment
facility "A", storm sewer pipes, inlet locations, or impervious surface square footage
calculations for the Mixed -Use or Progress Energy sites.
Wet Detention Basin "A":
The required surface area using 90% TSS removal efficiency for the wet detention
basin based on the post -development drainage area of 7.71-acres with 3.91-acres
impervious was calculated to be 9,303-square feet. The required volume for the f-
inch design storm was calculated to be 14,173-cubic feet.
Surface area for the wet detention basin at the permanent pool was designed to be
9,794-square feet. Storage volume for the 1-inch rainfall was designed to be 14,251-
cubic feet at the elevation of 24.41. Based on the proposed volume of the 1-inch
storage and the 11/2-inch drawdown orifice set at the permanent pool elevation
(23.50), the 1-inch runoff drawdown time was calculated to be 3.3-days.
Infiltration Pond "B":
The required volume for the infiltration pond based on the post -development
drainage area of 4.64-acres with 3.20-acres impervious was calculated to be l 1,297-
cubic feet. The volume proposed for the infiltration Pond `B" was calculated to be
11,329•-cubic feet. Based on the proposed volume of the pond, the drawdown time
was calculated to be 8.60-hours.

Transmittal
Linda,
Attached are modifications to the Progress Point stormwater permit (SWS 020637) which I
described to you via e-mail on I2/27/2002. As I previously mentioned, the NCDOT did not
approve our previous driveway location on Eastwood Road and required that we move it as
far to the east as possible. Unfortunately, this site plan revision forced us to relocate
stormwater treatment facility `B' to a location other than what you had previously approved.
Please let me know if you have any questions or need additional information to complete
your review of the proposed modifications.
Sincerely,
Mike Davidson, RLA

Eastern Soil ProjectNo, 02-1.00
Dear Mr. Chapman:
Eastern Soils Limited (ESL) is pleased to submit thi.s report for the subject project. A
copy will be seat to Mr. Tim Grady, Kirnley-Horn & Associates (K-H) in Raleigh, North
Carolina.
Background
Mr. Tim Grady (K•H), requested that we perform an assessment of the seasonal high
water table (SHWT) conditions at the subject site. The property is approximately 15 acres
of land with an office building used by Progress Energy (formerly Carolina Power & Light
Company) and an electrical substation. Most of the property is undeveloped and foxested.
We understand that Progress Energy is plaarting to subdivide the property for commercial
development. The SHWT information is needed for stormwater managernert facility
design.
Field Activities and Observations
Mr. Grady provided a site reap with 10 suggested locations for boring. Nine borings were
made during this project. The baring site designated 13-5 was left out because of its
proximity to the electrical substation and the property line (see attached field site map).
'Mine borings were advanced to a depth of 94 inches below,gl qund surface (bgs).in the
approximate locations depicted on the site map. Our field descriptions of the soil
conditions are attached for reference,

The property has been extensively drained in the area of and around the perimeter of the
electrical substation. The ditches are about six feet in depth and are apprtaxurates 6 to 8
feet in width. There was no water in the ditches, though the ditch bottoms were moist, at
the time of our site visit. The area has Experienced a recent rainfall deficit.

The depth to the SHW .r is estimated. The information contained in the Sail Survey of
Now Hanover County, North Carolina (Map Sheet 20, USDA-SCS, 1974) indicates that
the site soils are Levan sand (Le) and Murville fine sand (Mu), These soils normally Dave a
SHWT at depths of 0 to 1.0 ft. bgs. The soil colors that we observed are consistent with
poorly to very poorly drained soils. Extensive drainage modification on the site and in the
surrounding area have lowered ,.be local water table, resulting in a rnuch deeper SHWT.
Estimated Hydraulic Conductivity (K,,a,

Linda,
Thank you for your letter indicating that you have approved the master plan revision for the Mixed -Use site at
Progress Point. We are pleased to know that improvements to the Progress Energy and Mixed -Use site (Phase 1
only) will soon be able to commence.
Unfortunately, we recently discovered that site plan revisions will be required on the northern side of the Progress
Point property due to comments that were issued by the NCDOT. The proposed access drive location on
Eastwood Road was not approved and will only be allowed if it is moved to the northeastern corner of the property
creating a greater separation from the Military Cutoff/Eastwood Road intersection. The new access point will
require the previously approved stormwater pond '13' be moved to the west and will require a re -design in order to
meet quality and storage requirements set forth by DENR and the City of Wilmington. The revisions will only take
place north of the Mixed -Use site and will not alter in any way the previously approved stormwater treatment facility
'A', storm sewer pipes, inlet locations, or impervious surface square footage calculations for the Mixed -Use or
Progress Energy sites.
We understand that the previously mentioned revisions will require a modification to the Stormwater Management
Permit Number SW8 020637 and we anticipate re -submitting those to your office shortly. Please feel free to call
me at 919-653-2928 if you have any questions or need additional information.
Sincerely,
Mike Davidson, RLA

On December 12, 2002 , the Wilmington Regional Office received a plan revision to
Stormwater Management Permit Number SW8 020637, It has been detennined that a formal
permit modification is not required for the proposed changes. The plans provide for the
development of Lot 3, permitted for a maximum of 100,581 ft' of built -upon area under the
permit. The plans indicate that 93,654 ftz is proposed. We are forwarding you an approved copy
of the revised development plans for Lot 3 for your files. Please add the enclosed plan sheets to
the previously approved Master Plan set.
PIease be aware that all terrns and conditions of the permit issued on November 27, 2002,
remain in full force and effect. Please also understand that the approval of this revision to the
approved plans is done on a case -by -case basis. Any other changes to this project including the
sale of the property, must be approved by this office prior to construction. If it is determined that
the proposed revision will require a modification to the permit or a separate permit, you will be
notified.

Linda,
Please find attached our site and drainage plans for the mixed -use site at Progress Point.
During our meeting in August, you mentioned that after the Progress Point master plan had
been approved, we needed to submit detailed contruction plans for each individual site
within the approved master plan. The Progress Point master plan (SW8 020637) allows for
a total of 100,581 SF of impervious areas for the mixed -use site. The total proposed
impervious square footage for this site is below maximum allowable amount which has
been permitted and can be found on sheet C3 in the site data table. Please let me know if
we can provide any additional information.
Sincerely,
Mike Davidson

IV. INFILTRATION BASIN OPERATION AND MAINTENANCE AGREEMENT
1. After every runoff producing rainfall event and at least monthly inspect the infiltration system for erosion,
trash accumulation, vegetative cover, and general condition. _
2. Repair eroded areas immediately, re -seed as necessary to maintain adequate vegetative cover, mow
vegetated cover to maintain a maximum height of six inches, and remove trash as needed.
3. After every runoff producing rainfall event and at least monthly inspect the bypass, inflow and overflow
structures for blockage and deterioration. Remove any blockage and repair the structure to approved design
specifications.
4. Remove accumulated sediment from the pretreatment system and infiltration basin annually or when depth
in the pretreatment unit is reduced to 75% of the original design depth. The system shall be restored to the
original design depth without over -excavating. Over -excavating may cause the required water table
separation to be reduced and may compromise the ability of the system to perform as designed. Removed
sediment shall be disposed of in an appropriate manner and shall not be handled in'a manner that will
adversely impact water quality (i.e. stockpiling near a stormwater treatment device or stream, etc.).
A benchmark shall be established in the pretreatment unit. The benchmark will document the original
design depth so that accurate sediment accumulation readings can be taken. The measuring device used to
determine the depth at the benchmark shall be such that it will give an accurate depth reading and not
readily penetrate into accumulated sediments.
When the design depth reads 0.5 feet in the pretreatment unit, the sediment shall be
removed from both the pretreatmentunit and the infiltration basin.
5. If the Division determines that the system is failing, the system will immediately be repaired to original
design specifications. If the system cannot be repaired to perform its design function, other stormwater
control devices as allowed by NCAC 2H .I000 must be designed, approved and constructed.
I acknowledge and agree by my signature below that I am responsible for the performance of the five
maintenance procedures listed above. I agree to notify DWQ of any problems with the system or prior to any
changes to the system or responsible party.

Permit No. SW8 020637
11. SCHEDULE OF COMPLIANCE
No homeowner/lot owner/developer shall fill in, alter, or pipe any drainage feature (such
as swales) shown on the approved plans as part of the stonmwater management system
without submitting a revision to the permit and receiving approval from the Division.
2. The permittee is responsible for verifying that the proposed built -upon area for the entire
lot does not exceed the allowable built -upon area. Once the lot transfer is complete, the
built -upon area may not be revised without approval from the permittee and the Division
of Water Quality, and responsibility for meeting the built -upon area limit is transferred to
the individual property owner.
If an Architectural Review Committee (ARC) is required to review plans for compliance
with the BUA limit, the plans reviewed must include all proposed built -upon area. Any
approvals given by the ARC do not relieve the lot owner of the responsibility to maintain
compliance with the permitted BUA limit.
4. The permittee shall submit to the Director and shall have received approval for revised
plans, specifications, and calculations prior to construction, for any modification to the
approved plans, including, but not limited to, those listed below:
a. Any revision to the approved plans, regardless of size.
b. Project name change.
C. Transfer of ownership.
d. Redesign or addition to the approved amount of built -upon area.
e. Further subdivision, acquisition, or sale of the project area. The project area is
defined as all property owned by the permittee, for which Sedimentation and
Erosion Control Plan approval was sought.
f. Filling in, altering, or piping of any vegetative conveyance shown on the approved
plan.
The Director may determine that other revisions to the project should require a
modification to the permit.
6. The Director may notify the permittee when the permitted site does not meet one or more
of the minimum requirements of the permit. Within the time frame specified in the notice,
the permittee shall submit a written time schedule to the Director for modifying the site to
meet minimum requirements. The permittee shall provide copies of revised plans and
certification in writing to the Director that the changes have been made.
7. The stormwater management system shall be constructed in it's entirety, vegetated and
operational for its intended use prior to the construction of any built -upon surface.
8. During construction, erosion shall be kept to a minimum and any eroded areas of the
system will be repaired immediately.
9. Upon completion of construction, prior to issuance of a Certificate of Occupancy, and
prior to operation of this permitted facility, a certification must be received from an
appropriate designer for the system installed certifying that the permitted facility has been
installed in accordance with this permit, the approved plans and specifications, and other
supporting documentation. Any deviations from the approved plans and specifications
must be noted on the Certification.
10. If the stormwater system was used as an Erosion Control device, it must be restored to
design condition prior to operation as a stormwater treatment device, and prior to
occupancy of the facility.

Permit No. SW8 020637
11. Decorative spray fountains will not be allowed in the stormwater treatment system
12. The permittee shall at all times provide the operation and maintenance necessary to assure
that all components of the permitted stormwater system function at optimum efficiency.
The approved Operation and Maintenance Plan must be followed in its entirety and
maintenance must occur at the scheduled intervals including, but not limited to:
a. Semiannual scheduled inspections (every 6 months).
b. Sediment removal.
c. Mowing and revegetation of side slopes.
d. Immediate repair of eroded areas.
C. Maintenance of side slopes in accordance with approved plans and specifications.
f. Debris removal and unclogging of structures, orifice, catch basins and piping.
g. Access to all components of the system must be available at all times.
13. Records of maintenance activities must be kept and made available upon request to
authorized personnel of DWQ. The records will indicate the date, activity, name of
person performing the work and what actions were taken.
14. Prior to the sale of any lot, deed restrictions must be recorded which limit the built -upon
area per lot to the amount as shown on the Project Data Sheet, per Section 1, Part 2. The
recorded statements must follow the form:
a. The following covenants are intended to ensure ongoing compliance with State
Stormwater Management Permit Number SW8 020637, as issued by the Division
of Water Quality under NCAC 2H.1000.
b. The State of North Carolina is made a beneficiary of these covenants to the extent
necessary to maintain compliance with the Stormwater Management Permit.
C. These covenants are to run with the land and be binding on all persons and parties
claiming under them.
d. The covenants pertaining to stormwater may not be altered or rescinded without
the express written consent of the State of North Carolina, Division of Water
Quality.
C. Alteration of the drainage as shown on the approved plans may not take place
without the concurrence of the Division of Water Quality.
f. The maximum built -upon area per lot is as follows: Lot 1 @10,890 ftz; Lot 2
@63,059 ft2; Lot 3 @100,581 W; Lot 5 @48,065 ft2; and Lot 6 @48,913 f1 . This
allotted amount includes any built -upon area constructed within the lot property
boundaries, and that portion of the right-of-way between the front lot line and the
edge of the pavement. Built upon area includes, but is not limited to, structures,
asphalt, concrete, gravel, brick, stone, slate, coquina and parking areas, but does
not include raised, open wood decking, or the water surface of swimming pools.
g. All runoff on the lot must drain into the approved and permitted system. This may
be accomplished through providing roof drain gutters which drain to the street,
grading the lot to drain toward the street, or grading perimeter swales and
directing them into the pond or street. Lots that naturally drain into the system are
not required to provide these measures.
h. Each lot whose ownership is not retained by the permittee, shall submit a separate
stormwater permit application to the Division of Water Quality and receive a
permit prior to construction.

Dear Ms. Lewis:
We are writing in response to your Request for Additional Information letter
dated November 15, 2002 on the above referenced stormwater submittal.
Enclosed are two (2) copies of the revised master stormwater plans (Sheets C3
and C4), revised wet detention basin supplement (page 1 of 4) and wet pond
calculations addressing the comments as described below.
Response to Comments:
Comment: As previously requested, please show the required elevations,
inverts, flow spreader lip elevations, width and length -of the 30' vegetated
filter for the infiltration basin. A vegetated filter for the wet pond is not
required since the 90% TSS chart was used
Response: The infiltration basin elevations for the bypass system stormwater
pipe (30-in RCP) flared end section and the flow spreader lip have been
shown on the Site Details Plan (Sheet C4 — "Vegetated Filter Detail for
Pond `B"').
The width and length of the vegetated filter for the infiltration basin has been
revised on the Site Details Plan (Sheet C4 — "Vegetated Filter Detail for
Pond `B"').
The proposed vegetated filter for the wet pond (Pond `A') has been removed
from the plans.
2. Comment: The vegetated filter in not simply a connecting ditch from the
infiltration basin to the existing ditch. Based on the existing contours in the
ditch, the vegetated f lter for the infiltration basin will be 2' below the bottom
of the ditch, meaning that it will be continually fill of water. The reason for

having a vegetated filter is to provide additional TSS removal via a thin sheet
flow across a grassed area. Locating they filter underwater negates the
reason for having it. Please either provide a suitable design for the
vegetated filter (i.e., raise the elevation of the filter so that it will be above
the anticipated water elevation in the ditch, or redesign Infiltration Basin B
to a wet pond as was done for Basin A.
Response: The proposed elevation at the end of the vegetated Filter has been
raised to approximately 2-feet above the bottom of the ditch. The proposed
12-foot wide vegetated filter has been modified to 40-feet in length with a
slope of L-percent toward the ditch:
3. Comment: The wet pond temporary pool elevation reported on the
supplement should be 24.41, not 26.1. 771e temporary pool elevation
corresponds to the elevation of the first outlet above the permanent pool. I
have made the necessary changes to the supplement.
Response: The temporary pool elevation of the wet pond has been revised to
be 24.42.
Wet pond supplement (SWU-102, page 1 has been revised and enclosed).
4. Comment: Please provide a table of the elevations, areas and volumes for the
pond and forebay to support the conclusions regarding the volumes provided
in the pond and forebay. What is the surface area provided at elevation
24.41? 1 can't tell if the "temporary pool" surface area in the calculations is
for elevation 24.41 or 26.1 since it isn't labeled.
Response: Wet detention pond elevations, areas and volumes spreadsheet has
been enclosed for the pond and forebay.
The surface area at elevation of 24.42 has been calculated to be 18,483-
square feet.

Progress Point Master Plan
New Hanover County -
Dear Mr. Chapman:
The Wilmington Regional Office received previously requested information for the
Stormwater Management Permit Application for Progress Point Master Plan on September 5,
2002. 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. As previously requested, please show the required elevations, inverts, flow
spreader lip elevations, width and length of the 30' vegetated filter for the
infiltration basin. A vegetated filter for the wet pond is not required since the 90%
TSS chart was used.
2. The vegetated filter is not simply a connecting ditch from the infiltration basin to
the existing ditch. Based on the existing contours in the ditch, the vegetated filter
for the infiltration basin will be 2' below the bottom of the ditch, meaning that it
will be continually full of water. The reason for having a vegetated filter is to
provide additional TSS removal via thin sheet flow across a grassed area.
Locating the filter underwater negates the reason for having it. Please either
provide a suitable design for the vegetated filter (i.e., raise the elevation of the
filter so that it will be above the anticipated water elevation in the ditch, or
redesign Infiltration Basin B to a wet pond as was done for Basin A.
3. The wet pond temporary pool elevation reported on the supplement should be
24.41, not 26.1. The temporary pool elevation corresponds to the elevation of the
first outlet above the permanent pool. I have made the necessary changes to the
supplement.
4. Please provide a table of the elevations, areas and volumes for the pond and
forebay to support the conclusions regarding the volumes provided in the pond
and forebay. What is the surface area provided at elevation 24.41? I can't tell if the
"temporary pool" surface area in the calculations is for elevation 24.41 or 26.1
since it isn't labeled.
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 December 15,
2002, or the application will be returned as incomplete. The return of a project will necessitate
resubmittal of all required items, including the application fee.

NARRATIVE
The proposed development is located at the southeast quadrant of the intersection of
Eastwood Road and Military Cutoff Road,
The 11.83-acre site currently occupies a Carolina Power and Light building, asphalt
parking areas and drives. Currently, runoff from the site enters an existing drainage
ditch that runs along the eastern property line.
The proposed site plan contains sir buildings, asphalt parking areas and drives with
connections to adjacent parcels, an off -site asphalt road and concrete sidewalks.
NCDENR: First 1-inch of Rainfall
Wet Detention Basin "A":
A 90% TSS removal efficiency and a post -development drainage area of 7.71-acres
with 3.91-acres impervious was used for the design of the wet detention basin. The
required surface area of the permanent pool was calculated to be 9,303-square feet.
The required volume for the 1-inch design storm was calculated to be 14,173-cubic
feet.
Surface area for the wet detention basin at the permanent pool was designed to be
9,794-square feet. Storage volume for the 1-inch rainfall was designed to be 14,251-
cubic feet at the elevation of 24.41. Based on the proposed volume of the 1-inch
storage and the 1 112-inch drawdown orifice set at the permanent pool elevation
(23.50), the 1-inch runoff drawdown time was calculated to be 3.3-days.
Calculations for the 1-inch storm event are enclosed.
Infiltration Pond "B":
The required volume for the infiltration pond based on the post -development
drainage area. of 4.48-acres with 2.72-acres impervious was calculated to be 9,699-
cubic feet. The volume proposed for the infiltration Pond " B" was calculated to be
14,044-cubic feet at the elevation of 25.40. Based on the proposed volume of the
pond, the drawdown time was calculated to be 3.2-hours. Calculations for the I -inch
storm event are enclosed.

Dear Ms. Lewis:
We are writing in response to the Request of Additional Information made by
NCDENR for the subject project dated August 22, 2002.
Enclosed are two (2) sets of the revised plans addressing the comments as
described below. Also enclosed are copies of the revised stormwater application,
calculations and an 1 1" x 17" plan with the proposed drainage areas "A" and "B"
delineated.

Per a site visit conducted on Friday, August 16, 2002, the regional soils scientist
determined that the seasonal high water table for Basin A is too high. Please
either raise the bottom elevation to 25, or revise the application to a wet pond
submittal.
Basin "A" has been designed as a wet detention basin. The plans, calculations and
report have all been revised accordingly. A wet detention basin supplement (form
SWU-102) has been completed for basin "A" and is enclosed.

2. Since you do not know for sure how the lots will develop, you must include all
of the property area of the lots in the drainage area. Please revise and provide
a revised drainage area delineation map. (see enclosed map)
Drainage areas have been re -delineated. Portions of the site that are within a
drainage easement for the existing ditch, which runs around the perimeter of the
substation, have not been included in the drainage areas.
3. if the drainage areas change as a result of #2 above, please revise the
calculations to account for the increased drainage area.
Calculations have been revised to account for the increase in drainage areas.
Stormwater application form SWU-101, page 2 of 4 has been revised accordingly.
4. The storage elevations and volumes reported on the supplements must
correspond to the bypass weir elevations shown in the flow control structure
details on sheet C4. Please either increase the weir elevations to 26, or reduce
the storage elevations reported on the supplement to 25.35 and 25.40
respectively.
The infiltration basin supplement (SWU-103, page 1 of 3) for basin "B" has been
revised to reflect a storage volume and elevation corresponding to 25.40.
The infiltration basin supplement for basin "A" has been replaced with the wet
detention basin supplement.
5. Please show the required elevations, inverts and widths specific to each basin
on the vegetated filter detail. Please also specify the type of flow spreader
mechanism, i.e., half round _" 0 pipe, a concrete box, etc.
The vegetated filter detail has been revised to show the required information.
6. The outlet from flow control structure #1 to the vegetated filter appears to flow
over the weir without going into a pipe. Please make this clear on a separate
vegetated filter detail, since the current detail shows only a pipe outlet.
Flow control structure #1 has been eliminated. A wet detention basin has been
designed to replace the proposed infiltration basin.
7. Please make it clear on the now structure details which side of the box has a
grated top and which has a solid top. Then entire top of Basin A can be grated,
but for Basin B, only the side where all the pipes come into the box can be
grated. The side that goes to the bypass needs to be a solid top.
The bypass control structure for basin "B" has been designed with solid tops.
Neither side of this structure will incorporate a grated top.

Just to let you know- the Regional Soil Scientist and I went to the ,site this past Friday morning and
found that the seasonal high water table at the proposed site for Pond A was elevation 23, not 21.5.
You have the option of raising the bottoin elevation for pond A to 25 or you Can convert Pond A into
a Suet detention basin, since the receiving stream is not class SA. The permanent pool elevation must
be at or above the SHWT elevation.

Eastern Soil Project O. 02-100
Dear MY. Chapman:
Eastern Soils Limited (ESL) is pleased to subrrAt this report for the subject grojec*. A
copy will be sent to Mr. Tim Grady, Kimley-Horn & Associates (K H) in Raleigh, north
Carolina.
Background
Mr. Tim Grady (K-H), requested that we perform, an assessment of the seasonal high
water table (SHWT) conditions at the subject site. The property is approximately 15 acres
of land with an office building used by Progress Energy (formerly Carolina Power & Light
Company) and an electrical substation. Most of the property is undeveloped and forested.
We understand that Progress Energy is planning to subdivide the property for cor>:uttercial
development. The SITWT information is needed for stormwater management facility
design.
Field AettVities and Observations
Mr. Grady provided a sit, snap with 10 suggested locations for boring. Nine borings were
made during this project. The boring site designated B-5 was left out because of its
proxirnity to the electrical substation and the property line (see attached field site map).
dine borings were advanced to a depth of 94 inches below grpund surfa . fts}.in the
approximate locations depicted on the site map, Our field descriptions of the soil
conditions are attached for reference.

The depth to the SHWT is estimated. The information contained in the Soil Sun�ey of
New !Hanover Cowity, North Carolina (Map Sheet 20, USDA-SCS, 197.4) indicates that
the site soils are Leon sand (Le) and Muraille fine sand (Nfu). These sails nurmaI]yhave a
SIPXT at depths of 0 to 1,0 ft_ bgs. The soil colors that we observed are consi%cnt with
poorly to very poorly drained sci.ls. Extensive drainage modification on the site and in the
surrounding area have lowered the local water table, resulting, in a much deeper SHWT.
Estimated Hydraulic Conductivity
The estimated,K„ is >6,0 in./hr throughout the soil profiles we observed, with the
exception of the spodic horizons (Bh) encountered in borings B.3,.$-7,94, B-9, and
3-I d, The estimated I for ihvse soil horizons is >0.6 in./hr_

OVERVIEW PO. Box 33066 -
Raleigh, North Carolina
27636.3068
The proposed development (Appendix A) is located at the southeast quadrant of the
intersection of Eastwood Road and Military Cutoff Road.
The 11.83-acre site currently occupies a Carolina Power and Light building, asphalt
parking areas and drives (Appendix B). Currently, runoff from the site enters an
existing drainage ditch that runs along the eastern property line.
Appendix C includes the post -development plan with the proposed drainage areas
delineated. The proposed site plan contains six buildings, asphalt parking areas and
drives with connections to adjacent parcels, an off -site asphalt road and concrete
sidewalks and containing 89% impervious in the drainage areas captured and treated
by the infiltration ponds.
A proposed grading and drainage plan has been included in Appendix D. This plan
contains the proposed on -site storm water system including the infiltration ponds
designed to capture the on -site and off -site storm water runoff. Please refer to the
following paragraphs for the on -site storm water system and detention design criteria.
On -Site Storm Water System
There are two drainage areas for the proposed site, drainage area "A" and "B".
Appendix E contains the calculations for the proposed on -site and off -site storm
water systems for these drainage areas designed to a 10-year storm event. The runoff
coefficients (C) used for the on -site system were calculated using the weighted
average of the proposed impervious and pervious areas. Impervious runoff
coefficient used in the calculations was 0.95 and the pervious runoff coefficient used
was 0.20. The time of concentration (Tc) used in the calculations was set at 5-
minutes.

Infiltration Pond
Since the calculated post -developed storm water runoff was greater than the pre -
development runoff as described above, detention devices had to be designed to
reduce the proposed development runoff to the pre -development rates. The pre -
development condition, as per the City of Wilmington requirement, was based on no
existing development.
Infiltration facilities were designed according to the guidelines set forth in the
"Stormwater Best Management Practices", NCDENR manual, April 1999. The
infiltration ponds ("A" and "B") were designed to discharge the calculated runoff
from the post -development to pre -development flow rates.
Infiltration fond "A": q�
The infiltration pond rim elevation was set a 47 -feet, and the bottom elevation was
23.5-feet (two -feet above the calculated seasonal high water table). Side slopes were
set at a 11 ratio. An offline bypass control structure (str #1) was designed to allow
runoff greater than the design volume of the pond to bypass the pond. The crest
' elevation of a 7.5-foot weir internal to the bypass control structure was set at 25.35-
feet.
Storm water runoff discharged from this bypass control structure drained into an
existing storm water ditch that runs along the eastern property line. Design
calculations for the infiltration pond, bypass control device and the routing results are
enclosed in Appendix H. The routing results in Appendix H also include the
calculated water surface elevations of 25.93-feet and 26.35-feet for the 10-year and
50-year storm events, respectfully.
Infiltration Pond "B":
The infiltration pond rim elevation was set at 47.0-feet, and the bottom elevation was
24.0-feet (two -feet above the calculated seasonal high water table). Side slopes were
' set at a 3A ratio. An offline bypass control structure (str #2) was designed to allow
runoff greater than the design volume of the pond to bypass the pond. The crest
elevation of a 7.5-foot weir internal to the bypass control structure was set at 25.4-
feet.
Storm water runoff discharged from this bypass control structure drained into an
' existing storm water ditch that runs along the eastern property line. Design
calculations for the infiltration pond, bypass control device and the routing results are
enclosed in Appendix 1. The routing results in Appendix I also include the calculated
water surface elevations of 26.01-feet and 26.28-feet for the 10-year and 50-year
' storm events, respectfully.

Infiltration Pond "A":
' The required volume for the infiltration pond based on the post -development
drainage area of 4.40-acres with 3.91-acres impervious was calculated to be 13,573-
cubic feet. The volume proposed for the infiltration Pond "A" was calculated to be
47,205-cubic feet. Based on the proposed pond and the volume of the pond, the
drawdown time was calculated to be 5.87-hours. Calculations for the 1-inch storm
event are enclosed in Appendix J.
' Infiltration Pond "B":
The required volume for the infiltration pond based on the post -development
drainage area of 3.04-acres with 2.72-acres impervious was calculated to be 9,438-

20,682-cubic feet. Based on the proposed pond and the volume of the pond, the
drawdown time was calculated to be 4.64-hours. Calculations for the 1-inch storm
event are enclosed in Appendix J.
