Re: Additional Information, Stormwater Project No. SW8 881011, Remote piloted
Vehicle Maintenance Shop, Building 1747
Dear Christine:
Enclosed please find revised documents in response to your add info request #2 of
October 3, 2013.
1. See the top of calculation sheet 8/12 for the drawdown calculations for the 2" storm.
We have provided drawdown calculations for both the 1.5" and the 2" storms. The 2"
storm volume is 16,080 cubic feet which equates to a temporary pool elevation of 22.0'.
In calculating the stage/storage table, the volume associated with the 22.0' elevation is
16,128 cubic feet (p. 5/12 of calculations). The difference is all rounding.
2. Changed on the supplement the storage volume to be provided in the temporary pool to
that associated with the 2" vs. the 1.5" storm. The value is 16,128 cubic feet as
associated with the 22.0' elevation. Changed the drawdown from 2.8 to 3.3 days on the
supplement as well in order to reflect the longer time to decant the larger volume.
We appreciate your assistance with this project. Should you have any questions, please
do not hesitate to give me a call.

Stormwater Project No. SW8 881011
Remote Piloted Vehicle Maintenance Shop, Building 1747
Onslow County
Dear Mr. Paul:
The Wilmington Regional Office received a modified Express Stormwater Management Permit
Application for Remote Piloted Vehicle Maintenance Shop, Building 1747 on September 11,
2013. 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. Please confirm the volume provided in the temporary pool. The temporary pool
elevation, considered to be the elevation of the next available outlet, appears to be set at
22.0 ft. The supplement indicates that the provided temporary pool volume is 12,060 ft3;
however, the calculations indicate that the volume provided at an elevation of 22.0 ft is
16,128 ft3.
2. Please confirm the drawdown calculations presented on page 7 of the calculations. I
appears that the temporary storage elevation (22.0 ft) was not used in the drawdown
calculations; instead the minimum required storage elevation appears to have been
used.
3. Due to the relatively minor nature of these comments, the express additional information
review fee has been waived.
4. 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 October 11, 2013, 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.

Dear Christine:
Enclosed please find revised documents in response to your add info request of
September 23, 2013.
1. Corrected the seasonal high water table on the calculation sheet page 2/12. I had put
the ground elevation at the boring location vs. the actual SHWT elevation. Corrected the
SHWT elevation on the supplement from 20.5' to 20.0'. Have the permanent pool set
within 6 inches of that elevation.
2. Have provided revised plan sheets showing the rerouting of the existing swale
between building 1750 and the proposed parking lot. The swale now goes around the
pond as we had originally intended.
3. See the top of calculation sheet 8/12 for the drawdown calculations for the 2" storm.
We have provided drawdown calculations for both the 1.5" and the 2" storms.
4. Changed on the supplement the storage volume to be provided in the temporary pool to
that associated with the 1.5" vs. the 2" storm.
We appreciate your assistance with this project. Should you have any questions, please

Dear Mr. Paul:
The Wilmington Regional Office received a modified Express Stormwater Management Permit
Application for Remote Piloted Vehicle Maintenance Shop, Building 1747 on September 11,
2013. 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 seasonal high water table (SHWT) section on Page 2 of the calculations indicates
that the ECS "report shows the SHWT at an elevation of 22.5 ft which corresponds with
the existing pond lever'. However the proposed permanent pool is set at 20.5 ft, which is
more than 6 inches below the identified SHWT elevation. The August 21, 2013 report
from ECS indicates that the SHWT for the boring associated with the Building 1747
location is 30 inches below grade. It is difficult to tell from the boring map the existing
grade of the boring location. Please provide the ground elevation of the boring. If the
permanent pool elevation is set more than 6 inches below the SHWT elevation, then a
detailed, site specific evaluation discussing the items identified on pages 10-9 and 10-10
of the BMP manual must be provided.
✓2. Please confirm the drainage area of the pond and either include any offsite drainage that
is directed to the BMP or redirect the offsite runoff to bypass the BMP. The existing
conditions and the proposed grading plan both indicate that a ditch is located between
the proposed parking lot and Building 1750 and may direct runoff to the wet detention
pond. According to the revised drainage area map, this ditch and its associated
drainage area is outside of the proposed drainage area.
3. Please confirm the drawdown calculations. It appears that the temporary storage
elevation (22.0 ft) was not used in the drawdown calculations; instead the minimum
required storage elevation appears to have been used.
�4. Please confirm the storage volume to be provided in the temporary pool. The volume
presented in the supplement, 16,080 ft3, appears to be the volume of the 2 inch design
storm used to satisfy federal requirements.
Due to the relatively minor nature of these comments, the express additional information
review 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.

Stormwater Management Narrative
Construct Parking Lots, Hadnot Point and French Creek
MCB Camp Lejeune, NC
Building 1747
This project proposes to construct a new asphalt paved parking area in a gravel surfaced
parking area currently being used. The parking area will be an extension of an existing
parking lot that was approved under the Coastal Stormwater Regulations. The site is
partially located in the existing stormwater boundary. The existing stormwater boundary
will be increased from 213,444 SF to 221,099 SF. The runoff from the existing
impervious areas around the site will be diverted around the drainage basin for the new
parking area. The project will convert 16,348 SF (0.375 Ac.) of gravel surfaced area into
asphalt parking area. The project built -upon area percentage is 55.7.
The existing 1989 era stormwater pond which currently captures the runoff from the
existing gravel surfaced parking area being improved along with the existing permitted
4.9 acre drainage area consists of a very elongated ditch type configuration. The pond is
not constructed according to the latest NCDENR practices such as average depth,
vegetated shelf and plantings. This project will upgrade the existing wet pond to current
practices and take in all of the existing and proposed runoff. The reconstructed wet pond
will be sized for 90% TSS removal. The SA/DA ratio is 3.73%. The pond average depth
is 4.0 feet and it is sized to contain and drawdown the runoff volumes associated with
both the 1.5 and 2.0 inch storms. The minimum required pond surface area is 8,247 SF
compared to the 8,426 SF provided.
The work area does not impact any wetlands.
The site drains to the New River which is classified as SQNSW (Index #19-(15.5)). All
work is located greater than fifty feet from surface waters.
1.5 acres of the site will be disturbed by this project in order to construct the parking area.
The sedimentation and erosion control plan is being concurrently submitted.
The soils on the site are classified as Baymeade by the Onslow County Soil Survey.
Baymeade is described as a loamy sand at the depths to be disturbed by this project.
The property is owned by the Federal Government. There are not any known historic
sites on the property.

Reference: Report of Seasonal High Water Table Estimation
FC-308 and Buildings 313 and 1747
Camp Lejeune, Onslow County, North Carolina
ECS Project No. 22.19323
Dear Mr. Avolis
ECS Carolinas, LLP (ECS) recently conducted an estimation of the Seasonal High Water Table
(SHWT) for the proposed stormwater best management practice (BMP) areas for three parking
lots; FC-308, Building 313, and Building 1747 located on Camp Lejeune, Onslow County, North
Carolina. This letter, with attachments, is the report of our estimation.
Field Testing
On August 19, 2013, ECS conducted an exploration of the subsurface soil and groundwater
conditions at three requested locations shown on the attached Boring Location Plans (Figures
1,2, and 3). The purpose of this exploration was to estimate the SHWT of the in place soils for
the design of for the proposed stormwater BMP areas. ECS met with Mr. Kevin Avolis with
Avolis Engineering in order to locate the borings. ECS explored the subsurface soil and
groundwater conditions by advancing one hand auger boring into the existing ground surface at
the requested boring locations. ECS visually classified the subsurface soils and obtained
representative samples of each soil type encountered. ECS recorded the SHWT and
groundwater level observed at the time of each hand auger boring. The attached SHWT sheet
provides a summary of the subsurface conditions encountered at each hand auger boring
location.
The groundwater level and the SHWT were estimated at each boring location below the existing
grade elevation. Below is a summary of each boring location. _

Stormwater Management Narrative
Construct Parking Lots, Hadnot Point and French Creek
MCB Camp Lejeune, NC
Building 1747
This project proposes to construct a new asphalt paved parking area in a gravel surfaced
parking area currently being used. The parking area will be an extension of an existing
parking lot that was approved under the Coastal Stormwater Regulations. The site is
partially located in the existing stormwater boundary. The existing stormwater boundary
will be increased from 213,444 SF to 221,099 SF. The runoff from the existing
impervious areas around the site will be diverted around the drainage basin for the new
parking area. The project will convert 16,348 SF (0.375 Ac.) of gravel surfaced area into
asphalt parking area. The project built -upon area Vercentage is 55.7.
The existing 1989 era stormwater pond which currently captures the runoff from the
existing gravel surfaced parking area being improved along with the existing permitted
4.9 acre drainage area consists of a very elongated ditch type configuration. The pond is
not constructed according to the latest NCDENR practices such as average depth,
vegetated shelf and plantings. This project will upgrade the existing wet pond to current
practices and take in all of the existing and proposed runoff. The reconstructed wet pond
will be sized for 90% TSS removal. The SA/DA ratio is 3.73%. The pond average depth
is 4.0 feet and it is sized to contain and drawdown the runoff volumes associated with
both the 1.5 and 2.0 inch storms. The minimum required pond surface area is 8,247 SF
compared to the 8,426 SF provided.
The work area does not impact any wetlands.
The site drains to the New River which is classified as SC;NSW (Index 419-(15.5)). All
work is located greater than fifty feet from surface waters.
1.5 acres of the site will be disturbed by this project in order to construct the parking area.
The sedimentation and erosion control plan is being concurrently submitted.
The soils on the site are classified as Baymeade by the Onslow County Soil Survey.
Baymeade is described as a loamy sand at the depths to be disturbed by this project.
The property is owned by the Federal Government. There are not any known historic
sites on the property.

Dear Mr. Mitchell:
On January 10, 1989, the Division of Environmental
Management issued you a Certification of Compliance with
Stormwater Regulations for the P-837 Remote Piloted V.M.S..
Stormwater Regulation 15A NCAC 2H. 1003 (k) (3) stipulates the
following:
Upon completion of construction, a registered
professional appropriate for the type of Stormwater system
designed must certify that the system was inspected during
construction and was constructed in substantial conformity
with plans and specifications reviewed by the division and
complies with the requirements of this Rule.
As of this date, our records indicate the required
engineer's certification has not been received. Operation of the
stormwater system prior to submission of the required
certification is in violation of NCAC 2H.1003(1) in accordance
with NCGS 143-215.3 and is subject to enforcement action pursuant
to NCGS 143-215.6. If construction of the subject project has
not been completed, please provide written notification to this
office which includes the present phase of construction and the
expected date of construction completion. Written notification
is required to be provided by May 26, 1991. If the facility has
been constructed and placed in operation, please submit the
required certification (attached) immediately. Construction is
considered "complete" at the time the project is occupied by an
owner or tenant for its intended use.
