FOR STORMWATER EXPRESS REVIEW
March 03, 2009
PROJECT NAME: Bachelor Enlisted Quarters, MCAS P-636
MCB Camp Lejeune, NC
Onslow County
PROJECT DESCRIPTION: This project is for the construction of barracks and a parking lot to be located on the Marine
Corps Air Station Base at Camp Lej eune. The owner is the United States Marine Corps. There are no wetlands located
within the area of the development.
Stormwater from the site will drain into C;NSW waters located in the White Oak River Basin (Index # 19-17-(0.5)). The
project will be high density utilizing wet detention basins as treatment for runoff, conveyed to the ponds using an
underground stormwater collection system and above ground flumes / swales. This project is subject to NPDES
Phase II requirements. Proposed impervious for the site is 45.6%. Runoff from the building on the East side of the
building will be collected in a gutter system and discharged into a collection system that discharges into the pond. The
remaining sides of the building will use splash blocks and the water will be directed into the collection system. The
project will have direct access onto both Campbell Street and Schmidt Street with the entrance aprons draining back to the
road side swales. The project limits on P-636 doesn't contain the jogging trail that runs along the site. Thejogging trail
will be permitted under a different permit.

- Pre-dev. to Pond
CN Pre Developed = 70 (SCS) composite value determined as follows:
+/- 7,194 sf of soils are A, woods fair (CN = 36)
+/- 68,214 sf of soils are B, woods fair (CN = 60)
+/- 109,094 sf of soils are D, woods fair (CN = 79)
Area = 184,502 sf or 4.24 acres
Hydraulic length = 300 ft
Basin slope - 0.9%
Qmax for pre-dev 1-yr/24-hr storm = 2.49 cfs
POST -DEVELOPED CONDITIONS (see hydrograph summary and reports):
- Post-dev. to pond
CN Post Developed = 75 (SCS) composite value determined as follows:
+/- 105,969 sf of impervious surface (CN = 98)
+/- 60,344 sf of soils are A, open space -good cond. (CN = 39)
+/- 25,281 sf of soils are B, open space -good cond. (CN = 61)
(105,969 x 98 + 60,344,x 39 + 18,189 x 61) / 184,502 = 75.0

Good: >75% ground cover.
4 Actual curve number is less than 30; use CN = 30 for runoff computations.
5 CN's shown were computed for areas with 50% woods and 50% grass (pasture) cover. Other combinations of
conditions may be computed from the CN's for woods and pasture.
6 Poor. Forest litter, small trees, and brush are destroyed by heavy grazing or regular burning.
Fair. Woods are,grazed but not burned, and some forest litter covers the soil.
Good: Woods are protected from grazing, and litter and brush adequately coverthe soil.

Idle lands (CN's are determined using cover types
similar to those in table 2-2c).
1. Average runoff condition, and la = 0.28.
2. The average percent impervious area shown was used to develop the composite CN's. Other assumptions are as follows: impervious
areas are directly connected to the drainage system, impervious areas have a CN of 98, and pervious areas are considered equivalent
to open space in good hydrologic condition. CN's for other combinations of conditions may be computed using Figure 8.03c or 8.03d.
3. CN's shown are equivalent to those of pasture: Composite CN's may be computed for other combinations of open space cover type.
4. Composite CN's to use for the design of temporary measures during grading and constriction should be computed using Figure 8.03c
or 8.03d based on the degree of development (impervious area percentage) and the CN's for the I r d a y s �6�s?.,h�i� Cwst1, PC

Dear Mr. Baker:
Natural Resources
Dee Freeman
Secretary
The Wilmington Regional Office received a State Stormwater Management Permit Application for Bachelor Enlisted
Quarters, P-636 on March 5, 2009. A preliminary review of that information has determined that the following
information is needed to continue the stormwater review:
Please take another look at the exhibits provided for P-636. The drainage areas between the two
exhibits (Ex 1.1 and Ex 1.2) appear to have slight differences, specifically the driveway accessing
Schmidt St and the northeast corner of the Schmidt St parking lot. Please provide consistent
drainage area maps.
2. Due to the minor nature of this comment, the express fee has been waived.
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 March 18, 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.
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. If you have any questions concerning
this matter please feel free to call me at [phone] or email me at [e-mail].

FOR STORMWATER EXPRESS REVIEW
January 16, 2009
PROJECT NAME: Bachelor Enlisted Quarters, MCAS P-636
MCB Camp Lejeune, NC
Onslow County
PROJECT DESCRIPTION: This project is for the construction of barracks and a parking lot to be located on the Marine
Corps Air Station Base at Camp Lejeune. The owner is the United States Marine Corps. There are no wetlands located
within the area of the development.
Stormwater from the site will drain into C;NSW waters located in the White Oak River Basin (Index # 19-17-(0.5)). The
project will be high density utilizing wet detention basins as treatment for runoff, conveyed to the ponds using both an
underground stormwater collection system and above ground flumes / swales. This project is subject to PDES
Phase [I equirements. Proposed impervious for the site is 57.9%. As with all high density stormwater projects, al runof
from impervious surfaces will be collected and conveyed to the wet detention basins for treatment. The project will have
direct access onto both Campbell Street and Schmidt Street.
PROJECT BMP: high density wet detention basin

Gentlemen:
The Express Slonnwater Scoping meeting for the 3 projects listed above has been scheduled with Christine Nelson on Tuesday, January 27, 2009 at
11:00 AM here in the Wilmington Regional Office. Christine already has a meeting scheduled with David Towler at 10:00 AM that day so I'm pretty
sure Dave is planning to here anyway.
The projects are subject to the Coastal Stormwater Rules that took effect in October, 08. Projects that propose treatment measures for stormwater are
required to have soils reports specifically describing the area(s) where the treatment is proposed - including seasonal high water table elevation(s).
Please review the submittal requirements, attached. Please note that the checklist for a complete application is in the bmp manual and should be
reviewed. The most current supplement sheets, operation & main. forms, etc. should be downloaded for each project since they change often.
'Please respond ASAP to confirm and reserve the scope meeting date on these projects.
Thanks,
Janet Russell

1. Legible vicinity map.
2. Complete Soils Report.
3. PDF formatted site plan with the boring locations to be tested. Site plans should
be emailed or hand -delivered only. Illegible faxed maps will not be accepted.
All proposed infiltration areas and existing, active utility lines located Kithin the proposed
basin/trench must be marked and flagged. If these areas are not flagged, the Soils Scientist
reserves the right to decline to do the investigation. If the proposed infiltration system will be
located in an area of existing pavement and there is no open area nearby, equipment capable of
breaking through the impervious layer must be provided. The soils investigation does not take
the place of a soils report prepared by an appropriate professional. The Soils Scientist will only
verify the soil conditions that ate reported in the Soils Report, and make a determination as to

the suitability of the site to meet the infiltration design requirements under NCAC 2H.1000, and
assumes no liability should the system fail.
