Subject: State Stormwater Management Permit No. SW8 070926
Wounded Warrior Complex — Basketball Court Addition
High Density Wet Detention Pond and Infiltration Basin Project
Onslow County
Dear Mr. Baker:
Dee Freeman
Secretary
The Wilmington Regional Office received a complete modified Stormwater Management
Permit Application for the Wounded Warrior Complex on June 19, 2012. 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, Session Law 2006-246, and
Session Law 2008-211, as applicable. We are forwarding Permit No. SW8 070926 dated
June 21, 2012, for the construction, operation and maintenance of the BMP's and built -upon
areas associated with the subject project.
On August 5, 2009, the Governor signed Session Law 2009-406. This law impacts any
development approval issued by the Division of Water Quality under Article 21 of Chapter 143
of the General Statutes, which is current and valid at any point between January 1, 2008, and
December 31, 2010. The law extends the effective period of any stormwater permit that is set
to expire during this time frame to three (3) years from its current expiration date. On August
2, 2010, the Governor signed Session Law 2010-177 which grants an extra year for a total of
four (4) years extension.
Accordingly, this permit, which was set to expire on November 16, 2017, shall now be
effective from the date of issuance until November 16, 2021, and shall be subject to the
conditions and limitations as specified therein. Please pay special attention to the conditions
listed in this permit regarding the Operation and Maintenance of the BMP(s), procedures for
changes of ownership, transferring the permit, and renewing the permit. Failure to establish
an adequate system for operation and maintenance of the stormwater management system,
to transfer the permit, or to renew the permit, will result in future compliance problems.
The following modifications are included and covered by this permit:
• 5,008 square feet of pervious area has been removed from drainage area 1 and added
to drainage area 4.
Y The addition of a covered basketball court and an ADA accessible ramp in front of the
Headquarters Building within drainage area 4.
C The addition of 25,000 square feet of future impervious area to drainage area 1.

PROJECT NARRATIVE - MODIFICATION SW8-070926
EROSION & SEDIMENT CONTROL
1. GENERAL INFORMATION
a. Name of Project: P1378 — WOUNDED WARRIOR HOPE AND CARE CENTER
b. Street Address: West of Hospital Corps Road, currently unnamed road
City: Camp Lejeune
County: Onslow
C. Acres in Tract: Property is all located within the Boundary of Camp Lejeune
d. Acres Being Disturbed: This is a Modification of an existing permit.
The total acreage of the project is 26.56
The actual Wounded Warrior site, Sub Basin #4 is 10.41 acres.
Additional acreage disturbed = 6.36, not previously disturbed.
e. Acres in Wetlands: None
f. Ownership Information: United States Marine Corps
Description of Proposed Development:
The original permit was for the Barracks Building (BEQ). The permit was then
modified for the construction of the Wounded Warrior Hope and Care Center and
the Battalion Headquarters Building.
The next modification was for a concrete pad to provide a surface for trailers
located just west of the Headquarters building.
The next modification was to install a solar array in the parking lot adjacent to the
BEQ.
The current modification is to add a covered basketball court and associated
sidewalks behind the Headquarters building, a sidewalk infront on the
Headquarters building between the existing sidewalk and the existing roadway,
modification to a proposed monument (reduction in impervious), and a modification
to the location of the pond outfall pipe.
The increase in impervious surface is as follows:
Pre -Modification % Impervious = 33.47%
Developed % Impervious = 34.48%

Dee Freeman
Secretary
The Wilmington Regional Office received an Express Stormwater Management Permit
Application to modify the Wounded Warrior Complex permit on May 22, 2012 with additional
information received on June 14, 2012. 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 drawdown time for the wet detention ponds must be based on the required storage
volume, not the provided storage volume (please refer to Section 10.3.9). Please re-
evaluate the drawdown time and selected orifice diameter for Pond 1 as it appears that a
2.5" orifice will drawdown the required storage volume quicker than 2 days.
2. The express additional information fee has been waived for this request for additional
information.
3. Please keep in mind that changing one number may change other numbers and require
the calculations, supplements, and other supporting documentation to be updated.
Verify all numbers are correct to ensure consistency in the application documents.
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 June 20, 2012, 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 email or fax your request for a time
extension to the Division at the address and fax number at the bottom of this letter. Please note
that a second significant request for additional information may result in the return of the project.
If the project is returned, you will need to reschedule the project through the Express
coordinator for the next available review date, and resubmit all of the required items, including
the application fee.
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.

Wounded Warrior Complex
Onslow County
Dear Mr. Baker:
Dee Freeman
Secretary
The Wilmington Regional Office received an Express Stormwater Management Permit
Application to modify the Wounded Warrior Complex permit on May 22, 2012. 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. For wet detention pond 1, please evaluate the following:
a. The supplement identifies the temporary pool elevation is lower than the permanent
pool elevation. It appears these two numbers may be swapped.
b. The calculations use a 3 foot average depth to determine the SA/DA ratio; however
the supplement indicates an average depth of 3.5 was used. The original design
calculations used option 1 to determine an average depth of 3 ft.
--� c. Based on the calculations, it appears that a 2.5" orifice will drawdown the required
storage volume quicker than 2 days. (0.084 cfs > 0.076 cfs) Please adjust the
orifice diameter, as necessary.
It appears that the feature to the south has been identified as surface waters on an
adjacent permit, the Base Entry Road, SW8 090630. Please confirm whether or not this
feature is considered surface waters and if so, identify the top of bank and 50 foot buffer
on the plans. In addition, if this feature is surface waters, please reconsider the design
of the outlet to meet the requirements of a vegetated buffer. Section 2(a)(6) of Session
Law 2008-211 defines a vegetated buffer as an area of natural or established vegetation
directly adjacent to surface waters through which stormwater runoff flows in a diffuse
manner to protect surface waters.
3. Please provide two (2) copies of the updated drainage area maps.
4. Please provide an updated wet detention pond operation and maintenance (O&M)
agreement for pond 1. Since a new supplement is needed, which no longer is combined
with the O&M agreement, the separate O&M agreement is needed.
5. The express additional information fee has been waived for this request for additional
information.
6. Please keep in mind that changing one number may change other numbers and require
the calculations, supplements, and other supporting documentation to be updated.
Verify all numbers are correct to ensure consistency in the application documents.

'Gentlemen,
I have attached the pdf of the request for additional information for the modification to the Wounded Warrior Complex
stormwater permit (SW8 070926). 1 have also attached a plan sheet from the permit I mention in item #2 demonstrating
that this feature appears to have been previously identified as surface waters.
I have put a due date of May 30 on this in hopes that if you can turn it around quickly, I can get it done before I leave on
vacation. However, I will only be working a half day on the 31". If the information can't be provided that quickly, then
we can extend the due date until I return on June 11.
Let me know if you have any questions.
Christine

Dear Ms. Nelson:
Hoggard / Eure Associates, P.C. has reviewed the comments dated May 24, 2012 and offers the following responses.
The enclosed submittal package includes the following:
1. Wet Detention Basin Supplement— POND #1 Revised, Comment 1a, b, c
2. Wet Detention Pond Sizing Calculations
3. Original of the applicable Supplimental Form
4. Two Copies (2) of Drainage Area Maps
COMMENT RESPONSES:
For wet detention pond 1, please evaluate the following:
a. The supplement identifies the temporary pool elevation is lower than the permanent pool elevation. It
appears these two numbers may be swapped.
The elevations on the supplement have been swapped, thus corrected.
b. The calculations use a 3 foot average depth to determine the SA/DA ratio; however the supplement
indicates an average depth of 3.5 was used. The original design calculations used option 1 to determine
an average depth of 3 ft.
The average depth on the supplement has been changed to indicate 3 ft, as per the original
calculations.
p. Based on the calculations, it appears that a 2.5" orifice will drawdown the required storage volume quicker
than 2 days. (0.084 cfs > 0.076 cfs) Please adjust the orifice diameter, as necessary.
The calculations have been revised. The calculations provided in the submittal last week were
performed using the required volume thru the 2.5" orifice. The revised number has been
calculated using the provided volume. �' (^' F VEVED
JUN 1 4 4u1L

2. It appears that the feature to the south has been identified as surface waters on an adjacent permit, the Base
Entry Road, SW8 090630. Please confirm whether or not this feature is considered surface waters and if so,
identify the top of bank and 50 foot buffer on the plans. In addition, if this feature is surface waters, please
reconsider the design of the outlet to meet the requirements of a vegetated buffer. Section 2(a)(6) of Session Law
2008-211 defines a vegetated buffer as an area of natural or established vegetation directly adjacent to surface
waters through which stormwater runoff flows in a diffuse manner to protect surface waters.
Based on conversations with Camp Lejeune, it has been decided not to modify the out fall
previously approved. All modifications in this area shall be removed from the project. This
includes erosion control measures.
3. Please provide two (2) copies of the updated drainage area maps.
Updated drainage area maps shall be sent via overnight mail. These revised maps will not
indicate the revised outfall pipe.
4. Please provide an updated wet detention pond operation and maintenance (O&M) agreement for pond 1. Since a
new supplement is needed, which no longer is combined with the O&M agreement, the separate O&M agreement
is needed.
The updated wet detention O & M agreement for Pond 1 is attached.
The plans and specifications submitted for your review reflect the contract documents that will be utilized for
construction after permit approval.
Please contact me if any questions or comments arise during your review. I will be able to visit your office or speak to
you by telephone if necessary to help with your review.
Very truly yours,
G SOCIATES, P.C.

Dear Ms. Nelson:
Floggard 1 Eure Associates, P.C. has reviewed the comments dated June 14, 2012 and offers the following responses.
The enclosed submittal package includes the following:
1. Wet Detention Basin Supplement - POND #1 Revised, June 191 2012
2. Wet Detention Pond #1 Sizing Calculations
3. Revised Drainage Area Calculations for SWU-1011 added 25,000sf future BUA
4. Revised page 3 of 4 for SWU-101, overall % Imperviousness
COMMENT RESPONSES:
1. The drawdown time for the wet detention ponds must be based on the required storage volume,
not the provided storage volume (please refer to Section 10.3.9). Please re-evaluate the
drawdown time and selected orifice diameter for Pond 1 as it appears that a 2.5" orifice will
drawdown the required storage volume quicker than 2 days.
An additional 25,000 square feet of future build upon area was added to the calculations to increase the
required temporary pool elevation. This increased volume increases the drawdown time to just over 2
days. No modification to the existing pond outlet structure shall be required.
The plans and specifications submitted for your review reflect the contract documents that will be utilized for
construction after permit approval.
Please contact me if any questions or comments arise during your review. I will be able to visit your office or speak to
you by telephone if necessary to help with your review.
