Stormwater Management Narrative
Courthouse Bay Regional Pond
MCB Camp Lejeune, NC
SW8 030720
This project provides for the construction of an 875 SF Pavilion (gazebo) in the existing
lawn area adjacent to building BB328. Building BB328 was one of the original buildings
constructed when the regional pond was constructed as a part of the Joint Maritime
Training Facility. The'pavilion site is located in the Regional Pond drainage area. The
Regional Pond current drainage area is 3,391,103
The regional pond permit was last modified on October 17, 2013 based on a file review at
NCDENR. The last permit revision indicates that the "Future on -site" BUA quantity
remaining is 191,837 SF for the current size of the pond. This Plan Modification will
reduce that amount to 190,962 SF. The total allowable BUA remains at 960,509 SF with
a percent impervious area remaining unchanged at 28.3%.
The pavilion will be located adjacent to an existing stabilized grass Swale through the
lawn area of building BB328. The swale eventually enters the collection system for the
regional pond.

IV. PROJECT INFORMATION
1. In the space provided below, briefly summarize how the stormwater runoff will be treated.
Stormwater for the project will be treated by the existing Courthouse Bay Regional wet basin sized for 85%
TSS removal. The existing wet basin has been constructed previously as part of a "Regional" stormwater
pond for the original Dining Hall Constructed in 2007. The current constructed pond was approved by
NCDENR in 2007 for 34.6%) BUA (762,276sf impervious) -reference Stormwater Permit No. SW8 030720
revised July 27 2010 and a potential build out condition that is not proposed to change at this time.
The enclosed project -Mess Hall Bldg. Addition will include a total impervious area of 5,643sf . The new
impervious area includes a 2060sf building addition, 1.600sf new sidewalk, 3.044sf new parking 00spaces)
and the removal of 1,061sf of existing sidewalk.
Because the existing pond currents built has excess capacity (i.e. can handle more development) and ample
store capacity for additional future development, this permit application is proposing to Maximize the
Future "Potential" BUA condition of the CURRENT Pond. The Maximum BUA threshold the current pond
can handle equal, 43.6%, or a total of 960,509sf of impervious area.
This Permit Modification is proposing a Max. Future QUA of 43.6%, that will include the 5,643sf of impervious
for the Mess Hall therefore totaling 767,.919sf today and allowing an add itional_192,590sf of impervious
remaining for the future.
In 2007, Permit Number SW8 030720 MOD permitted a "Total Build out" condition that includes a 2nd Phase
of the Pond being built out and expanded to accommodate up to 77.85 Acres including_up to 1,621,289sf
(37.22ac) of impervious area equating to a Max 47.8%, BUA. The impervious area has been permitted for
1 359 929sf of onsite and 261 360sf of offsite area. This phase will require additional construction to expand
the pond consistent with the Build out Plans submitted with the 2007 Permit Mod. This Build out is still
planned for the future consistent with the approved 2007 permit, and to clarify none of the Build out will
occur at this time.
2. a. If claiming vested rights, identify the supporting documents provided and the date they were approved:
❑ Approval of a Site Specific Development Plan or PUD Approval Date:
❑ Valid Building Permit Issued Date:
® Other: S\,1 .i Date:
b. Identify the regulation(s) the project has been designed in accordance with:
❑ Coastal SW —1995 ❑ Ph II — Post Construction
3. Stormwater runoff from this project drains to the White Oak River basin.
4. Total Property Area: 50.574 acres 5. Total Coastal Wetlands Area: n/a acres
6. Total Surface Water Area: n/a acres
7. Total Property Area (4) — Total Coastal Wetlands Area (5) — Total Surface Water Area (6) = Total Project Area':
50,574 acres
Total project area shall be calculated to exclude the follozoing: the normal pool of itupounded structures, the area
behoeen the banks of streams and rivers, the area below the Normal High Water (NHW) line or Mean High Water
(MHW) line, and coastal wetlands landward from the NHW (or MHW) line. Tire resultant project area is used to
calculate overall percent built upon area (BUA). Non -coastal wetlands landward of the NNW (or MHW) lure tnay
be included in the total project area.

Wet Detention Basin Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
The wet detention basin system is defined as the wet detention basin,
pretreatment including forebays and the vegetated filter if one is provided.
This system (check one):
® does ❑ does not incorporate a vegetated filter at the outlet.
This system (check one):
® does ❑ does not incorporate pretreatment other than a forebay.
Important maintenance procedures:
Immediately after the wet detention basin is established, the plants on the
vegetated shelf and perimeter of the basin should be watered twice weekly if
needed, until the plants become established (commonly six weeks).
No portion of the wet detention pond should be fertilized after the first initial
fertilization that is required to establish the plants on the vegetated shelf.
Stable groundcover should be maintained in the drainage area to reduce the
sediment load to the wet detention basin.
— If the basin must be drained for an emergency or to perform maintenance, the .
flushing of sediment through the emergency drain should be minimized to the
maximum extent practical.
— Once a year, a darn safety expert should inspect the embankment.
After the wet detention pond is established, it should be inspected once a month and
within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a
Coastal County). Records of operation and maintenance should be kept in a known set
location and must be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately. %

Project Narrative ;
P1256
Mess Hall Addition Courthouse Bay
Camp LeJeune, North Carolina
Novemher 30, 2010
The enclosed project is a 2,060si' building addition and minor parking lot expansion of 10 parking spaces to the
existing Courthouse Bay Mess Hall located off of Jackson Street and Horn Road at Catnp Lejeune. The
original Mess Hall was constructed in 2007. The area that the Mess Hall is located and its stormwater is
handled by a Regional Stormwater Management Facility that is located nearby the project. See below for
project specifics.
• The original Stormwater Permit for the Regional Stormwater Management Area is Permit Number
SW8 030720 approved on December 12, 2003. The Regional Stormwater Management Area was
modified in 2005. Permit No. SW8 030720MOD was approved by NCDENR on January 26, 2005.
• The original Dining Hall Building Project was built in 2007/2008 and was a modification of the
Stormwater Permit Number SW8 030720MOD permit that included modification to the Regional
Stormwater Management Area. The permit modification was approved on August 28, 2007 and
corrected on July 27, 2010.
• The existing Permit allows for 34.6% BUA. The existing pond as constructed has excess capacity for
stormwater that "although it has been built -has not -been permitted" by NCDENR. Therefore, this
permit MOD will be maximizing the build out of the existing constructed pond.
• 'Che project area as designated for the original permit for the Regional Stormwater Management area
will not change from the permit modification approved in 2007 and totals 50.574-acres.
• The analysis for the existing current pond shows the MAX BUA threshold equals 43.6% that equates
to 960,509sf of impervious. The existing permit (2007) allows for BUA 34.6% or 762,276sf
impervious development. Therefore, the difference between the existing permitted condition and the
"proposed" max BUA condition equals 198,233sf of which the Mess Hall Addition will use 5,643sf
and the remaining 192,590sf will be reserved for future construction.
• In 2007, Permit Number SW8 030720 MOD permitted a "Total Build out" condition that includes a
2"`I Phase of the Pond being built out and expanded to accommodate up to 77.85 Acres including up to
1,621,289sf (37.22ac) of impervious area equating to a Max 47.8% BUA. The impervious area has
been permitted for 1,359,929sf of onsite and 261,360sf of offsite area. This phase will require
additional construction to expand the pond consistent with the Build out Plans submitted with the
2007 Permit Mod, This Build out is still planned for the future consistent with the approved 2007
permit, and to clarify none of the Build out will occur at this time.
• This permit application is proposing "no" physical changes to the pond, just a new hydraulic analysis
maximizing the pond's current condition and some minor physical improvements to the Mess Hall.
• This Mess Hall Addition project will include a minor building addition (2,060sf), parking lot addition
of 10 spaces (3,044st), and some sidewalk improvements (net 539st) adjacent to the building's front
area totaling 5,643sf of impervious area.
• The total impervious area all ready permitted equals 762,276sf and if you add the addition of 5,643sf
(mess hall addition) will total 767,919sf —still well under the 960,509sf (43.6%n) Max threshold.
Therefore, an additional 192.590sf of FUTURE impervious will be permitted in the future meeting the
ponds full capacity.
• The disturbed area for the Mess Hall Addition project will be approximately 30.0004 or 0.69 acres,
and a revised Erosion Control Permit for the project has already been issued in September 2010.
