Dear Mr. Maimone:
The Wilmington Regional Office received a complete modified Stormwater Management
Permit Application for UNC-W Honors, International & Privatized Housing on December 18,
2008. Staff review of the plans and specifications has determined that the project, as
proposed, will comply with the Stormwater Regulations set forth in Title 15A NCAC 2H.1000.
We are forwarding Permit No. SW8 970128 Mod., dated December 19, 2008, for the
construction of the subject project.
This permit supercedes all previously issued stormwater permits, and shall be effective from
the date of issuance until March 7, 2015, and shall be subject to the conditions and limitations
as specified therein. Please pay special attention to the Operation and Maintenance
requirements in this permit. Failure to establish an adequate system for operation and
maintenance of the stormwater management system will result in future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have
the right to request an adjudicatory hearing upon written request within thirty (30) days
following receipt of this permit. This request must be in the form of a written petition,
conforming to Chapter 150E of the North Carolina General Statutes, and filed with the Office of
Administrative Hearings, P.O. Drawer 27447, Raleigh, NC 27611-7447. Unless such demands
are made this permit shall be final and binding.
If you have any questions, or need additional information concerning this matter, please
contact Linda Lewis, or me at [phone].

McKim & Creed Project #4999-0002 (40)
Design Narrative -Permit Modification
Existing UNCW Privatized Housing, Honors Housing & International Housing
(Permit No. SW08 970128 MOD)
On April 23, 2008 a Plan Revision to NCDENR Permit No SW08 970128 MOD was received by
UNCW. The plan revision included the re -allocation of 606-sf from proposed built -upon -area
(BUA) to future BUA. The plan revision resulted in 398,201-sf of proposed BUA and 606-sf of
future BUA.
The current permit modification request proposes to:
• Increase the Drainage Area (DA) from 28.128-acre to 30.779-acre and increase the Built -
Upon -Area from 9.155-acre to 10.124-acre (398,807-sf to 441,017-sf).
Wet Detention Basin Sizin¢
Wet Detention Basin 1 was originally sized to treat the first 1.0" of runoff from the BUA.
Additional proposed BUA directed to Basin 1 was sized to treat the first 1.5" of runoff. Basin 1
has ample surface area and temporary storage volume to treat the proposed increase in DA and
BUA. The following table summarizes the surface area and volume additions resulting from the
proposed Permit Modification.

Stormwater Project No. SW8 970128 Mod.
UNCW Privatized Housing, Honors and International Housing
New Hanover County
Dear Mr. Maimone:
The Wilmington Regional Office received previously requested additional information regarding
the modified State Stormwater Management Permit Application for UNCW Privatized Housing,
Honors and International Housing on November 10, 2008. A preliminary review of that
information has determined that the application is not complete. The following information is
needed to continue the stormwater review:
Please seal the revised pond calculations.
Please provide a new signed wet detention pond Operation and Maintenance
plan, downloaded from the website at this link:
http://h2o.enr state.nc.us/su/bmp forms htm
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 January 17, 2009, 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, email 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] or
email me at linda.lewis onncmail.net

RE: Stormwater Project No SW8 970128MOD
UNCW Privatized Housing, Honors.and International Housing
Dear Ms. Lewis:
In response to the comments from the November'7, 2008 letter, we offer the
following: `'
1. Please confirm my understanding of this project. It appears that you are
adding drainage area and allocating an additional 42,210 square feet of BUA
for an as yet unspecified project Are there any development plans for that
area available that can be approved at this time? If not, the permit will
require that those future development plans be submitted and approved
prior to construction as a pla: i n.vision. .
Response: The 42,210 additional square footage of built -upon -area (BUA) is a result
of down slope BLiA associated with the UNCW Phase III Privatized Housing that
could not be captured in the infiltration basins associated with NCDENR Perinit No
SW8 080406. Since the Phase III site was raised, approxiniately 5 feet above existing
grade, sonic down slope sidewalks and parking spaces could not be captured in the
infiltration ',asins. As previously stated in section III (1) of the storniwater
application, the additional BUA is a result of the UNCW Privatized Housing, Phase
III developn, tit.
2. Please be advised that form SVJU-101 was updated in March 2008, and will
be updated again very soon. Please,make' sure the application you submit is
the latest available, downloadeO.. from DWQ's website.
Response- A;1 project information .:as been transferred to the latest SWU-101 and is
provided.

3. Please check the calculated Rv value for the new drainage area that is subject
to the 1.5" design storm. A value of 0.57 is reported in the calculations, but I
am coming up with .383, based on a 37% impervious site.
Response: The Rv value of 0.57 is 1.5" (0.383) = 0.57. The spreadsheet has been
changed to show an Rv valne of 0.38.
4. Please check the minimum volume required. Since the Rv value is not correct,
the 1.5" volume associated with the additional drainage area is not correct.
Response. The minimnm volume has been checked and is correct:
0.05 + 0.009(37%) = (0.38112)*2.651ac*43560*1.5" = 5470cf
(0.05 + 0.009(37%)*1.5" = (0.57112)*2.651ac*43560 = 5470cf
5. Please provide an orifice drawdown calculation. The orifice is sized based on
the minimum design volume, not the total volume provided in the pond.
Since the total minimum volume has increased, the 3" orifice needs to be
checked to be sure that it is still able to draw down the total minimum
required storage volume in 2-5 days.
Response: The orifice drazodozon is attached for the proposed minimum temporary
volnne of 40,485-ef and the permitted maximum temporary vohmze of 79,638-cf.
If you have any questions, please do not hesitate to contact me at 910-512-9973.

Dear Mr. Maimone:
The Wilmington Regional Office received a modified State Stormwater Management Permit
Application for UNCW Privatized Housing, Honors and International Housing on October 7,
2008. A preliminary review of that information has determined that the application is not
complete. The following information is needed to continue the stormwater review:
Please confirm my understanding of this project. It appears that you are adding

yet unspecified project. Are there any development plans for that area available

development plans be submitted and approved prior to construction as a plan
revision.
2. Please be advised that form SWU-101 was updated in March, 2008, and will be
updated again very soon. Please make sure the application you submit is the
latest available, downloaded from DWQ's website.
3. Please check the calculated Rv value for the new drainage area that is subject to
the 1.5" design storm. A value of 0.57 is reported in the calculations, but I am
coming up with .383, based on a 37% impervious site.
4. Please check the minimum volume required. Since the Rv value is not correct,
the 1.5" volume associated with the additional drainage area is not correct.
5. Please provide an orifice drawdown calculation. The orifice is sized based on the
minimum design volume, not the total volume provided in the pond. Since the
total minimum volume has increased, the 3" orifice needs to be checked to be
sure that it is still able to draw down the total minimum required storage volume
in 2-5 days.
6. Please note that a revision to one number may have a domino effect on other
numbers, which may require revision of the applications, calculations,
supplements, plans, details, and associated documentation. Please verify all
numbers are correct to ensure consistency in the application documents.

I'm doing the completeness review for the modification you submitted to
SW8 970128 - UNCW Privatized Housing. Everything looked ok except for
the fact the grading plans didn't get sealed or signed. Can you get me
signed/sealed plans by tomorrow?

Checklist for Completeness Review of Stormwater Applications AcgE d
Each application for which a "Completeness Review' is needed will have this checklist printed on
yellow paper to distinguish it from other applications to be reviewed.
Ed M�at
at, and app the type of project, i.e., residential vs.
division vs single Io ,high density, w density, offsite, redevelopment, and
/ documentati s to prove ed.
L� Make sure that all required forms, supplements, O&M's, deed restrictions, signature
authorizations, etc., are included and contain original signatures.
If low density, make sure the BUA calculations include any common areas, clubhouse areas,
etc., and do a quick math check for addition errors.
Do a quick consistency check of the numbers used in the calculations vs. the numbers
— / reported on the application. For multiple BMP's pick one or two to check.
+� Ownership issues? Make sure the correct person has signed the application. If it's a
corporation or LLC, print off the NCSOS information sheet and latest annual report. Make
sure the person who signed is listed on the annual report with his/her correct title, or make
sure a signature authorization letter has been provided.
Make sure 2 sets of plans have been submitted, and that they include grading, layout (with
dimensions for all proposed BUA) and details.
Are the Wetlands delineated on the plans? Y /`NN By whom?
If the project drains to SA waters, make sure a USGStopo map with the site, the receiving
waters and the'/2 mile radius clearly shown to scale, is provided.
For high density projects, make sure the correct design storm is used, based on the receiving
^/ stream classification and the projects proximity to SA waters.
L�f Make sure appropriate details are provided such as roads, cul-de-sacs, curbing, sidewalk,
BMP's, level spreaders, vegetated filter strips, curb outlet swales, etc. Two of the most
common errors are that sidewalk is indicated on the plans, but not included in the BUA calcs
or shown with the road detail; and the road width used in the BUA calculations is less than
that shown on the road detail.
Are there any issues within the 575 ft ORW AEC?
If high density, make sure the plans and calculations are signed, sealed and dated.
If the project involves the subdivision of property or has outparcels, make sure a copy of the
Proposed Declaration of Covenants and Restrictions in legal format with all required
statements is provided, or that the appropriate standard deed restriction template, signed and
notarized, is provided.
Make sure that a Soils Report for all projects is provided, to determine if the required
separation to the SHWT is provided.
e For multiple HD systems & curb outlet swales, make sure a drainage area map is provided.
If the application is substantially incomplete, give the entire file with the check to admin (Jo
Casmer) to be returned to the applicant. Jo will keep copies of the return letters, application &
check.
❑ If the application lacks only a few minor items such that it can be made complete within 24
hours, you can email the consultant and request the information. Hold onto the package for
24 hours. If the information isn't received within 24 hours, give the application to Jo to return.
\ For Offsite projects:
The Designer's Certification for the offsite system has been submitted.
The deed restrictions have been recorded and a copy submitted.
The offsite system is in compliance with its permit.
Make sure the lot size hasn't changed from what was approved under the Master Plan and
that the correct lot number is referenced on the supplement form.
For Infiltration projects:
Soils report to determine SHWT, soil type and expected infiltration rate is provided.
Has Vincent conducted the site investigation? If Yes, date?
For infiltration projects, the maximum 2 acre inches of volume in any single system has not
been exceeded.
For Wet Ponds projects:
j\ Permanent pool to be located no lower than 6" below the estimated SHWT. Otherwise, the
incoming groundwater must be quantified and evaluated; the storage volume must be
verified; and the outlet needs to be evaluated for free drainage to the receiving waters under
SHWT conditions.

Design Narrative -Permit Modification
Existing UNCW Privatized Housing, Honors Housing & International Housing
(Permit No. SW08 970128 MOD)
On April 23, 2008 a, Plan Revision to NCDENR Permit No SW08 970128 MOD was received by
UNCW. The plan revision included the re -allocation of 606-sf from proposed built -upon -area
(BUA) to future BUA. The plan revision resulted in 398,201-sf of proposed BUA and 606-sf of
future BUA.
The current permit modification request proposes to:
• Increase the Drainage Area (DA) from 28.128-acre to 30.779-acre and increase the Built -
Upon -Area from 9.155-acre to 10.124-acre (398,807-sf to 441,017-sf).
Wet Detention Basin Sizine
Wet Detention Basin 1 was originally sized to treat the first 1.0" of runoff from the BUA.
Additional proposed BUA directed to Basin 1 was sized to treat the first 1.5" of runoff. Basin 1
has ample surface area and temporary storage volume to treat the proposed increase in DA and
BUA. The following table summarizes the surface area and volume additions resulting from the
proposed Permit Modification.

Checklist for Completeness Review of Stormwater Applications SW� Cl%mil ag
Each application for which a "Completeness Review" is needed will have this checklist printed on
yell w paper to distinguish it from other applications to be reviewed.
Q%nerme
rrative and appli on toil�ovided.
pe of project, i.e., residential vs.
subdivision vs. ing e o ighw density, offsite, redevelopment, and
dhat documentation neeWs to
—7�->❑ Make sure that all required forms, supplements, O&M's, deed restrictions, signature
authorizations, etc., are included and contain original signatures.
If low density, make sure the BUA calculations include any common areas, clubhouse areas,
etc., and do a quick math check for addition errors.
—�:)❑ Do a quick consistency check of the numbers used in the calculations vs. the numbers
reported on the application. For multiple BMP's pick one or two to check.
�—� Ownership issues? Make sure the correct person has signed the application. If it's a
corporation or LLC, print off the NCSOS information sheet and latest annual report. Make
sure the person who signed is listed on the annual report with his/her correct title, or make
sure a signature authorization letter has been provided.
Make sure 2 sets of plans have been submitted, and that they include grading, layout (with
7 dimensions for all proposed BUA) and details.
Are the Wetlands delineated on the plans? Y N By whom?
If the project drains to SA waters, make sure a USGS topo map with the site, the receiving
waters and the'/2 mile radius clearly shown to scale, is provided.
L For high density projects, make sure the correct design storm is used, based on the receiving
stream classification and the projects proximity to SA waters.
l ❑ Make sure appropriate details are provided such as roads, cul-de-sacs, curbing, sidewalk,
BMP's, level spreaders, vegetated filter strips, curb outlet swales, etc. Two of the most
common errors are that sidewalk is indicated on the plans, but not included in the BUA calcs
or shown with the road detail, and the road width used in the BUA calculations is less than
that shown on the road detail.
�y Are there any issues within the 575 ft ORW AEC?
If high density, make sure the plans and calculations are signed, sealed and dated.
If the project involves the subdivision of property or has outparcels, make sure a copy of the
Proposed Declaration of Covenants and Restrictions in legal format with all required
statements is provided, or that the appropriate standard deed restriction template, signed and
notarized, is provided.
Make sure that a Soils Report for all projects is provided, to determine if the required
separation to the SHWT is provided.
For multiple HD systems & curb outlet swales, make sure a drainage area map is provided.
If the application is substantially incomplete, give the entire file with the check to admin (Jo
Casmer) to be returned to the applicant. Jo will keep copies of the return letters, application &
check.
❑ If the application lacks only a few minor items such that it can be made complete within 24
hours, you can email the consultant and request the information. Hold onto the package for
24 hours. If the information isn't received within 24 hours, give the application to Jo to return.
For Offsite projects:
The Designer's Certification for the offsite system has been submitted.
The deed restrictions have been recorded and a copy submitted.
The offsite system is in compliance with its permit.
Make sure the lot size hasn't changed from what was approved under the Master Plan and
that the correct lot number is referenced on the supplement form.
For Infiltration projects:
Soils report to determine SHWT, soil type and expected infiltration rate is provided.
Has Vincent conducted the site investigation? If Yes, date?
For infiltration projects, the maximum 2 acre inches of volume in any single system has not
been exceeded.
\or Wet Ponds projects:
�J Permanent pool to be located no lower than 6" below the estimated SHWT. Otherwise, the
incoming groundwater must be quantified and evaluated; the storage volume must be
verified; and the outlet needs to be evaluated for free drainage to the receiving waters under
SHWT conditions.

Steve,
My responses:
1 - I don't believe so - you aren't changing the BMP design. I think the O&M
referenced in Linda's letter was in regards to the proposed previous pavement.
2 - As long as the plans demonstrate the grading and direction of flow, that sounds
fine with me. I'm aware these modifications are necessary to "fix" the previously
delineated drainage areas to show the true drainage areas and where the existing (and
some proposed) BUA is going. All that was provided with the submittal was a few
aerial photos which didn't show the drainage and BUA.
3 - If that is true, update Page 1 of the application to accurately reflect Mr.
Maimone's title and connection to UNCW.
4 - I'm not asking for the dry pond to be permitted with DENR, looking more to
acknowledge that its there, but not part of the state's requirements. I was asking
Nick about the dry pond because it affected the outfall of the stormwater, which was
different than what was approved.
Christine
Steve Thomas wrote:
Thanks Christine. We're working to get you the information requested
currently.
A couple of related comments:
1) Do you need new O&M forms for the BMP's affected by this drainage
area adjustment?
2) The plans we plan to provide (in response to your comment #2) will
show the new BUA and both the proposed and existing drainage areas.
This will give evidence that the water is going in the direction we
indicated on the overall drainage area map. There will not be any
"details" that I anticipate providing, as we are not proposing a
modification to the BMP's. Please correct me if I misunderstand your
request.
3) Charles A. Maimone (the gentleman who signed the applications) is
actually the "Vice Chancellor for Business Affairs" for the University.
He replaced Dr. Ron Core who retired a few months ago and who used to
sign the applications on behalf of the University-. You can view his
credentials at
http://www.northcarolina.edu/content.php/apps/secretary/admin directory/
view by org.php?org=34&admin=no&group=A
4) Nick mentioned an inquiry about the existing dry detention pond for
Seahawk Landing that is located at the eastern corner of that
development. That pond was added at the bequest of the City of
Wilmington for stormwater quantity control and is not part of the
NCDENR, DWQ permit for that project. As such, we have no data for this
pond, as we do not have any permit information for this project at all.
Thanks,
Steve

Steve,
I spoke with Nick a few moments ago regarding the modification you have
I of 9/30/2008 5:25 PM

Re: mod for UNCW permits 970128 and 060437
submitted for SW8 060437 into the regular stormwater program. I found
the following to be missing from this stormwater application submittal:
1. Updated supplements showing the change in drainage area and BUA.
2. Plans showing the grading, layout, and details. Ensure to include the entire
stormwater system (the dry detention pond and new outlet
location)
3. Applications are required to be signed by a person of at least the
Vice President level. Nick stated that the applicant, an Officer of UNCW
Corporation, was the acting President. Provide official documentation
from UNCW Corporation supporting that fact.
Nick also mentioned the fact that there was another modification for a
similar permit submitted to the regular program. I was able to track
down that submittal (SW8 970128). The submitted application did not
address the comments sent by Ms. Lewis on July 28, 2008 for the return
of the original modification received by this office on June 17, 2008 (see
attached). In addition to those comments, the latest submittal did not include
items 2 or 3 from above.
Please address these items and resubmit to this office before COB on
10/1. if these items cannot be completed by then, the applications and
checks will be returned.
Let me know if you have any questions!

McKim & Creed Project #4999-0002 (40)
Design Narrative -Permit Modification
Existing UNCW Privatized Housing, Honors Housing & International Housing
(Permit No. SWOS 970128 MOD1.2)
On April 23, 2008 a Plan Revision to NCDENR Permit No SWO8 970128 MOD was received by
UNCW. The plan revision included the re -allocation of 606-sf from proposed built -upon -area
(BUA) to future BUA. The plan revision resulted in 398,201-sf of proposed BUA and 606-sf of
future BUA.
The current permit modification request proposes to:
• Increase the Drainage Area (DA) from 28.13-acre to 30.78-acre and increase the Built -
Upon -Area from 9.16-acre to 10.13-acre (398,807-sf to 441,017-sf).
Wet Detention Basin Sizine
Wet Detention Basin 1 was originally sized to treat the first 1.0" of runoff from the BUA. For the
additional BUA directed to Basin 1, it was sized to treat the first 1.5" of runoff. Basin 1 has ample
surface area and temporary storage volume to treat the proposed increase in DA and BUA. The
following table summarizes the surface area and volume additions resulting from the proposed
Permit Modification.

Dear Mr. Core:
The Division received an incomplete, modified stormwater permit application for the project
listed above on June 17, 2008. Additional information was requested via email to your
consultant on June 23, 2008, but to date, there has been no response.'The application is being
returned because the package lacked the necessary elements to accept it for review. The
following information is needed to accept the application for review:
® In order to add pervious pavement, the permit must be modified. A completed and
signed permit application with an original signature is required.
® A completed wet pond supplement form, if the pond design parameters will be
changing.
A completed pervious pavement supplement form.
A signed Operation and Maintenance Plan.
The required application review fee of $505.00.
A soils report with Seasonal High Water Table elevation for all projects.
Please visit DWQ's website at http://h2o.enr.state.nc.us/su/bmp forms.htm to download the
latest available forms. Please provide the requested information and return the package to the
address below. If you have any questions, please do not hesitate to call me at [phone]
or email me at linda.lewis(aancmail.net.

Re: State Stormwater Permit Plan Revision to SW8 970128 Modification
UNCW School of Nursing Regional Energy Plant

Wilmington, North Carolina qt
NKT Project No. 06179-1 U n
Dear Mr. Pusey: C \
You recently granted a revision (April 23, 2008) to State Stormwater Permit No. SW8
970128 for the construction of a new energy plant on an existing service lot behind
Wagoner Hall on the UNCW main campus. Since this approval, we have received
comments from the NC Department of Insurance requiring additional 'fixed, non -slip"
pathways for handicap accessibility. The addition of these pathways would increase our
impervious surface area, and in turn, exceed the permitted impervious surface area. To
prevent this from happening, we have revised the plans to require all new pavement
and concrete be pervious. By changing the plans so all new pavement / concrete be
pervious, we reduced the current impervious area by 1,148 SF, which we would like to
allot as future impervious area. This revision request will show 397,659 SF of current
impervious surface area and 1,148 SF of future impervious area.
Please find enclosed two (2) sets of revised plans for the UNCW School of Nursing
Regional Energy Plant with the main revisions being the new NC Department of
Insurance required pathways, notes stating the new concrete / pavement shall be
pervious, a revised Site Data Table, and a pervious concrete detail.
We greatly appreciate your assistance on this project as you run through the process
again. Please let us know if you need any additional information.
Sincerely,
NORRIS, KUSKE & TUNSTALL

The following are the review comments and corrections for the above referenced plan:
1. Revise draw down orifice size and calculations to ensure that draw down occurs within 2 — 5
days.
Response: The draw down orifice has been revised from a 4" PVC pipe to a 3" PVC pipe to
ensure that draw down time is between 2 and 5 days. Sheet No. C7.00 has been revised to
reflect this. Two copies of the revised sheet are enclosed. The draw down calculations have
been revised to use the method outlined in an email from Linda Lewis dated 03 March 2005.
Two calculations have been included. The first calculates the range oj'oriftce sizes required to
draw down the runoff volunte front the first inch of rainfall (35016 cj). The second calculation
finds the range required to draw clown the volume of water stored from the permanent pool
elevation to the next available outlet (59410 cj). Both calculations show that a 3" orifice is
sufficient. An updated `Volume Calculations' spreadsheet is also enclosed with includes the
contour area at 28.0.
