Thank you for taking time from your schedule to meet with our team to discuss the referenced project
and our desire to better comply with the requirements for working with your Department. We truly
appreciate your explanations of the process of evaluation and approvals. The dialogue between us was
very helpful.
We at C Construction want to provide you with the best most accurate submittals we can to make the
process of review and approval as smooth as possible. I am committed to learning to work with your
Department and its employees to ensure achievement of our common goals. We expect to have more
projects in this area and are anxious to start construction on the referenced project as soon as possible.
I have taken steps to ensure that we honor our commitments to all parties involved. Yesterday we
attempted to contact Commander Scanlon for a meeting to discuss the issues we discussed in our
meeting. Unfortunately Commander Scanlon is not on Base until Tuesday. Our representatives will be
meeting with him to have substantive discussions on the four issues you identified to us. Mr., Applegate
and I have set up a meeting in Norfolk in mid September to discuss the same four issues directly with
LANTDIV representatives. I trust you can see that we are sincere in our efforts to work with you as
suggested. Again thank you for meeting with us. If I can be of any further assistance to you please
feel free to contact me directly.
Sincerely,

I don't know how much input you had regarding filling out the application and supplement, but there are a few
minor discrepancies.
The bottom areas for both basins used in the calculations is different than reported on the supplement.
Since the supplement pages are separate, please fax the corrected page 1 of the supplements and if
necessary, the sealed corrected calculations.
2. The calculations for Basin 42 appear to use 120,227 ft2, when in fact the volume is based on 113,693 ft2.
Please check the 113,693 reported on the top half of the first page of the calculations for Basin 2 as on -
site BUA. I think this should be revised to 107,159 ft2. The total BUA, including offsite, is 113,693 ft2,
as reported on the application,

STORMWATER MANAGEMENT PLAN NARRATIVE
BACHELOR ENLISTED QUARTERS
COURTHOUSE BAY AREA
MARINE CORPS BASE
CAMP LEJEUNE, NORTH CAROLINA
This project consists of the construction of two multi -story Bachelor enlisted quarters and
associated asphalt parking areas. The project is located in Onslow County and is subject to the
State of North Carolina Coastal Stormwater Regulations. The project is located adjacent to
Courthouse Bay which has a water surface classification of SA. As a result, stormwater runoff
from this high density (58% built -upon area) project is required to be treated is stormwater
infiltration ponds which will capture and infiltrate the runoff associated with a 1.5 inch rainfall
event.
This project incorporates two separate stormwater infiltration ponds which treat 4.19 and 4.87
acre drainage areas. Each of the ponds incorporate a stormwater bypass weir which discharges
runoff beyond the 1.5 inch rainfall event around the ponds. Each of the ponds will dewater in
less than one day.
The outlet of the bypass weir pipes for each of the two ponds has a 50 foot long vegetative filter
with a level flow spreader. This device will provide treatment of stormwater runoff which
bypasses the infiltration ponds during rainfall events in excess of 1.5 inches.
The site plan and site grading are designed with stormwater conveyance measures which provide
pretreatment of approximately 70% of the site runoff. The majority of all of the parking lot and
sidewalk runoff is collected in grass median swales with flat 10.1 side slopes. The longitudinal
slope of the swales averages 1.5%. The shallow, slow moving runoff in these median swale
sections is given the opportunity for a high level of vegetative filtering and infiltration. This
condition enhances the quality of any runoff bypassing the infiltration ponds.

excavating. Over -excavating may cause the required water table separation to be reduced and may
compromise the ability of the system to perform as designed. Removed sediment shall be disposed of in an
appropriate manner and shall not be handled in a manner that will adversely impact water quality (i.e.
stockpiling near a stormwater treatment device or stream, etc.).
A benchmark shall be established in the infiltration system. The benchmark will document the original
design depth so that accurate sediment accumulation readings can be taken. The measuring device used to
determine the depth at the benchmark shall be such that it will give an accurate depth reading and not
readily penetrate into accumulated sediments.
When the depth at the benchmark reads 0.25' , the accumulated sediment shall be removed
from the system.

MESSAGE:
Our soil scientist indicated that the SHWT was within 6" of the existing ground surface at the Pond 1 location.
The rules allow Infiltration basins to be located in fill material, but approval is given only on a case -by -case
basis. This pond's proximity to SA waters, the poor soils, and the high water table are all factors against
allowing the use of fill material. The soils at the proposed location for Pond l are not suitable for infiltration,
and the water table is too high. This Office is requiring that Pond 1 be relocated to higher ground, where the
required 2' water table separation can be obtained, and where the soil is more suitable for infiltration.
For Pond 2, as long as the existing ground is used as the proposed bottom, the facility will meet the 2' separation
requirement.
Rick has indicated that this is not a priority project. The information submitted on July 13, 2001, in response to
the June 28, 2001, additional information will be reviewed in turn.

Stormwater Project. No. SW8 010431
Batchelor Enlisted Quarters Replacement
N62470-99-R-9127
Onslow County
Dear Cdr. Scanlan:
The Wilmington Regional Office received a Stormwater Management Permit Application for Batchelor
Enlisted Quarters Replacement, on April 26, 2001. A preliminary review of that information has determined
that the application is not complete. The following information is needed to continue the stormvvater review:
A North Carolina registered professional, who meets the licensing requirements for the type of
system proposed, must sign and seal the plans and calculations.
2. Please provide sealed drawdown calculations. Base the calculation on the reported infiltration
rate and the bottom area of the basin. The 1.5" design storm must infiltrate within 5 days.
3. Please show elevations, grading, and the type of vegetation to be planted on the vegetated filter
detail. The pond section details provided are not detailed enough to show the grading and
elevations. The flow spreader of the filter should be placed on existing contour, allowing the
runoff to sheet flow over the 50' grassed filter area.
4. Infiltration systems must be offline. That means the excess design storm must bypass before
entering the basin. The current design will allow all runoff to enter- the basin, and be discharged
through the outlet structure after it goes through the basin. Due to these basins' proximity to SA
waters, -and in order to extend their useful life, no deviation from this requirement can be made.
5. Please label the bypass structures on the plans and details.
6. A portion of Basin 41 will be located in fill. This can only be approved on a case by case basis,
and will require a soils investigation by our soil scientist. A site visit is currently scheduled on
or about Monday, July 9. This visit is at the convenience of the soil scientist.
The supplements indicate that the storage elevations for each basin are 0.55 meters above the
bottom elevation, but the outlet structure details indicate a top elevation of only 0.49 meters
above the bottom. Please correct and revise. Whatever changes are made, please be sure to make
any other resulting changes to the plans, details, calculations, application, supplement, etc.

Please identify and dimension the structures located between and to each side of the proposed
buildings.
Your consultant has printed application forms that are formatted somewhat different than the
forms we use. instead of four pages, there are eight. On page 7, each submittal item needs to be
initialed, but the blanks were left off the printed form. Please initial. Copies of the forms are
available from the website, arNAiw.ncgov.com. In the QuickIinks area, select the Department of
Environment and Natural Resources; under Divisions/Agencies, select Division of Water
Quality; then select Applications/Forms. Select desired forms and print. I think you will need
Adobe Acrobat to print.
10. Please report the built -upon area numbers on page 4 of the application in square feet rather than
acres. Small numbers are easier to verify in square feet.
1 l . Please indicate in the calculations how you determined that the basins have provided the required
volumes. This is normally done by showing the surface areas at various elevations within the
basin, and calculating the cumulative volume to the storage elevation reported on the
supplement. Please be aware that the provided volume should be based on the reported storage
elevation, not the top elevation. Based on scaling and converting, approximately 9,100 fe is
provided at elevation 2.55M in Basin ##1, and 8,850 W at 3.55M in Basin 42, resulting in a
volume provided that is somewhat less than 29,400 cubic feet. Please correct and revise for both
basins.
12. Please circle the units for the infiltration rate on the supplement, either inches per hour or cubic
feet per hour per square foot.
Please note that this request for additional information is in response to a preliminary review. The
requested information should be received by this Office prior to July 28, 2001, 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 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 ofNCGS 143-215.1 and is subject to enforcement action
pursuant to NCGS 143-215.6A.

STORMWATER PERMIT # SW8 010431
THIS PROJECT CONSISTS OF THE CONSTRUCTION OF TWO MARINE CORPS
BARRACKS BUILDINGS AND ASSOCIATED ASPHALT PARKING AREAS AT THE
COURTHOUSE BAY AREA OF MARINE CORPS BASE CAMP LEJEUNE, NC. THE
PROJECT IS LOCATED ADJACENT TO COURTHOUSE BAY WHICH HAS A WATER
QUALITY CLASSIFICATION OF "SA". WATERS CLASSIFIED AS "SA" REQUIRE
STORMWATER INFILTRATION BASINS CAPABLE OF HOLDING THE FIRST 1.5
INCHES OF RUNOFF AND DRAWING IT DOWN WITHIN A 5-DAY PERIOD.
THIS PROJECT INCLUDES TWO SEPARATE STORMWATER INFILTRATION PONDS IN
ORDER TO MAINTAIN THE CONTRIBUTORY DRAINAGE AREA AT 5.0 ACRES OR
LESS. THE TWO PONDS ARE LOCATED APPROXIMATELY 300' FROM EACH OTHER.
EACH POND IS LOCATED GREATER THAN 50' FROM THE ADJACENT "SA" WATERS.
BOTH INFILTRATION POND SITES HAVE GREATER THAN TWO FEET OF
SEPARATION BETWEEN THE PROPOSED BOTTOM ELEVATION OF THE POND AND
THE SEASONAL HIGH GROUNDWATER TABLE ELEVATION.
THE FIELD MEASURED INFILTRATION RATES FOR THE TWO POND SITES ARE 1.68
' FN/HR (POND #1) AND 2.41 IN/HR (POND #2). BOTH PONDS ARE DESIGNED TO
ACCEPT AND TREAT THE OFF -SITE CONTRIBUTORY RUNOFF.
THE MAJORITY OF THE STORMWATER RUNOFF REACHING THE TWO
STORMWATER INFILTRATION PONDS IS PRETREATED BY WIDE, FLAT SIDE SLOPE
' GRASS DRAINAGE SWALES. THESE SWALES CAPTURE, TRANSPORT AND TREAT
ALL OF THE RUNOFF FROM THE ASPHALT PARKING AREAS. A HIGH DEGREE OF
STORMWATER PRETREATMENT, INCLUDING THE OPPORTUNITY FOR
' INFILTRATION, IS PROVIDED BY THIS PROJECT.

USE A "SMART WEIR" OR STORMWATER BYPASS STRUCTURE IN ORDER TO
PREVENT LARGER STORMWATER RUNOFF EVENTS FROM WASHING THROUGH
THE INFILTRATION POND. THIS DEVICE WILL ALLOW THE FIRST 1.5" FLUSH OF
RUNOFF TO BE CAPTURED AND TREATED.
SET BYPASS STRUCTURE WEIR AT 10.27 FT (3.13M)
SIZE STORMWATER BYPASS STRUCTURE AND PIPING TO PASS THE 100-YEAR
STORM EVENT.
MAINTAIN THIS CALCULATION AS CONSERVATIVE AND SIMPLE SINCE STORM
ROUTING WILL PROVIDE NO SIGNIFICANT ECONOMICAL BENEFIT DUE TO SHORT
PIPE OUTFALL DISTANCE.
