5. A secondary BMP in series with the wet pond (BMP 1) is provided to treat the
design storm discharged from the pond. The secondary BMP is a level spreader
and 50-foot vegetated filter strip designed to effectively infiltrate the design storm,
as described in Section 1.10 of this permit.
For each permitted BMP, the runoff in excess of the design storm must flow
overland through a 50' vegetated filter designed to pass the peak flow from the
10 year storm in a non -erosive manner.
The overall tract and each drainage area will be limited to the amount of built -
upon area indicated in Sections 1.2, 1.3, 1.9, 1.10 and 1.11 of this permit, and per
approved plans.
The runoff from all built -upon area within the permitted drainage area(s) of this
project must be directed into the permitted stormwater control system.

Subject: SW8 110611 consolication Mobile MOUT
Megan
I'm trying to consolidate the permits and am running across some questions:
Did you or Daniel do a BUA takeoff from each permit? I would like to have a takeoff (in square feet) to
attach to the permit as part of this consolidation. I can't get my takeoff to match the "new permit DA 1",
which I assume is the overall low density column. Please see revised attachment. It has been corrected
and should make a takeoff easier to complete.
2. How much BUA, in square feet, is assigned to each of the three new training areas? The application
lists only a lump sum total of buildings, parking and streets for all three together. The plan sheet with
the separate takeoffs by symbol number only has the impervious area in acres. When you consider
rounding, there is a relatively large range of square footages that will convert to that acreage. For
example, 0.11 acres will cover anywhere from 4600 sf up to 5000 sf. I have updated the attachment to
include the Training Areas broken out so you can see exactly where the numbers are coming form.
3. For BMP #4 (which was Basin #3 under 090330), the total impervious area is listed on the upper part of
the attachment as 26,572 sf, but it's listed as 29,185 in the lower part. If you have indeed added 2613 sf
to this BMP, you will need to submit revised design calculations, revised plans showing the additional
BUA, a new supplement form and a new O&M. I apologize. This was a typo on my part; I read the
information off of the original permit 090330 incorrectly. This has been corrected. We are not adding
any BUA to any existing BMP or permit.
4. The second page of the low density supplement is confusing. The Site Area (SA) is multiplied by a
Density Factor (DF). DF should be 0.12 (12%) in this case, but it looks like it's just 1. In part b. of the
low density calculation on the same supplement, the "Total BUA from lot listing" is reported as
1,842,846 sf. Where did this number come from? You should calculate the total allowable BUA as the
SA times 12% which comes out to 5,425,833 sf. Please note that in the upper half of the attachment,
the proposed impervious area is incorrectly reported as 5,425,866 sf. The number in part b. should be

i the proposed BUA plus the existing BUA taken from the application. What's leftover goes into the
"Future" box on the application. 1,842,846 SF is 42.3 acres —this is the BUA including all existing and
proposed BUA. However, I believe this is in error that should read 5,425,834. This has been corrected.
Also the typo in the attachment has also been corrected.
5. It is much more practical to report proposed BUA without stringing out the numbers to the hundredths.
would simply round those numbers up. For example, you've reported 11074.56 sf of buildings in the
overall Low density column. I think it would be much simpler and easier if it was reported as 11075 sf.
Noted, and changed.
6. My BUA takeoffs are as follows, broken down by permit. I'm missing a lot of existing BUA based on the
2,001,175 you have reported. Hopefully your takeoff will pinpoint how you came up with these numbers:
This was a mistake on my part. I have corrected the existing BUA. Please look to the attachment.

Janet,
I would like to formally request an Express Permitting Meeting with NC DENR for our Mobile MOUT Expansions SWPPP
and Erosion Control Permit. The Mobile MOUT Expansion SWPPP proposes to combine three existing SWPPP Permits
(SW8 060301; SW8 090330; SW8 051145) into one overreaching permit, while also adding acres for future development.
\.
Attached to this email, please find a project description, our request form, and a few site layout drawings. We would like
to schedule a meeting for the week of January 30th, if possible. Also, we need clarification on the SWPPP fee.
Please let me know if you require anything else to schedule the meeting.
Thank you,

Janet expressed some concerns to me about the plans that you will be submitting for this project. In order to
make sure you submit everything we need and don't end up with a returned project, I am writing this email to
provide you with some guidance.
This is a modification to combine 3 existing permits into one. The modification is necessary because of
overlapping permit boundaries. In addition to the previously approved existing development, you are proposing
to add three new Training Areas, A, B and C. We would need to see an overall plan with the new low density
project boundary delineated. It is most helpful if the individual previously approved projects are located on that
overall plan. We already have the detailed plans for those projects, so unless you are changing something on
any of those plans, you don't need to resubmit those detailed plans.
However, if you are adding new built -upon area or changing something on one of the previously approved
projects, then new detail plans for that project, i.e., grading, drainage and dimensions, are needed. The three
detail single sheets you provided with the Express request are labeled as Construction Staging and Logistics
plans. I do not know if these plans depict the existing development or if they are intended to depict the three
new training areas. These plans are only labeled with a "DO" number and the DO number is not related to the
existing development or to the proposed Training Areas A, B or C. These plans do not have any proposed
grading, spot elevations or dimensions, so they are not sufficient to obtain a stormwater permit.
The minimum plan requirements are listed on the low density checklist and on the individual BMP checklists
available on our website. Each checklist has three sections, one covering the details of filling in the
application/supplement, one covering the details of the calculations, and one covering the details for the plans.
Some of these checklists need to be updated, but the low density one is fairly up-to-date.

E-mail correspondence to and from this address may be subject to the North Carolina Public Records Law and may

Parsons is proposing combining several existing Stormwater Permits at Marine Corps Base Camp
Lejeune to create one large permit boundary covered by one SWPPP. The existing Stormwater Permits
are SW8 060301, issued March 15, 2006; SW8 051145, issued July 27, 2006; and SW8 090330, issued
April 23, 2009. These three existing permits overlap in places and together make up 40.99 acres of
disturbance.
Parsons will be overseeing the development of three new training areas in the vicinity of the
three existing permits. These training areas will together make up 1.281 acres of disturbance and create
0.881 acres of additional impervious surface within the proposed permit boundary. The training facilities
are identified within Parsons by their contract number. For the purposes of this SWPPP, they will be
identified as Training Areas A, B and C. Training Area A is a Mobile MOUT Sniper Tower. Training Area A
is 0.225 acres of disturbance, with 0.11 acres of that being impervious. Training Area B is a Mobile
MOUT FOB Expansion and will create 0.920 acres of disturbance, 0.730 of which will be impervious.
Training Area C is located at the MAC3 Range and will create 0.226 acres of disturbance, with 0.076
acres of impervious cover.
The total permit boundary proposed is 1,038 acres. The Built Upon Area at the completion of
Training Areas A, B and C will be 42.306 acres. This equates to a total of 4.075% impervious cover,
making this a low density SWPPP. There are 69.314 acres (6.677%) of wetlands (non -costal) within the
permit boundary; however, no wetlands fall within the new construction limits. The wetlands are
delineated on the site plans. A subsurface geotechnical investigation has been conducted by Matkin
Hoover Engineering and Survey, and a report compiled for each of the three new Training Areas. These
reports are available upon request from Megan Forthman, EIT with Parsons. Although the proposed
permit boundary is located within Onslow county and is classified as Costal Stormwater, the site does
not qualify as an Area of Environmental Concern under the Costal Area Management Act (LAMA), as the
site is not on oceanfront and does not meet any requirements of CAMA with the exception of its
location within a CAMA County (Onslow county). The entire proposed permit boundary lies within the
White Oak River Basin and drains to Bear Creek. The White Oak River Basin has no requirements for
vegetated buffers. Due to the Training Areas grading, no off -site runoff flows to the sites.
Training Area A consists of a gravel pad, an access road, and a concrete tower structure. The
existing flow from the site is 1.01 cfs. The proposed flow will increase to 1.26 cfs. This change in flow is
negligible over the size of the permit area. Training Area B consists of several ISO containers and a
penetrating wall. The ground cover within the site will be gravel. Existing flow off the site is 6.36 cfs.
After construction, the total flow will increase to 7.56 cfs, flowing at different rates off different parts of
the site. This change in flow is negligible over the size of the permit area. Training Area C consists of
several concrete block structures and walls. The ground cover will be sand. The existing flow conditions
are reduced across the site post construction. All stormwater within the proposed new construction
areas will sheet flow away from the structures off the sites. Training Area C will have drywell installed
onsite to collect some runoff.

Janet,
Thank you for scheduling the meeting. 10am EST sounds like a good time for the meeting. Also, will this meeting also
cover our Erosion Control Permits as well?
To answer your questions:
• Yes, this is a submittal meeting.
• We do not have an overall site plan that is to scale, but I have attached for your reference the site plans of the
three proposed construction areas.
• The final built upon area will be 42.3 acres. Currently there are 40.99 acres of BUA within the permit boundary.
Parsons has 3 construction projects totally 1.281 acres of BUA that bring the total BUA within the boundary to
42.3 acres.
• Our areas of new construction do not fall within 50' of the wetlands or surface waters — thank you for the
information regarding Camp Lejeune's policies.
Please let me know if you need any further information. Also, please let me know as soon as you have confirmed the
cost of the permits.
Thank you,

The Express Stormwater Meeting has been scheduled with Linda Lewis on Thursday, February 2. We are somewhat
flexible on the time. Please choose from 10, 10:30, 11:00 or 2:30. Let me know what you decide. Also, I need to verify
a couple of things, this is a "submittal meeting' and not a "scope'? You do have a site plan that is not an aerial photo -
one that shows the existing development to scale? Please clarify. Also, please verify that the built upon area will be
42.3 acres as stated in your narrative? (seems like a lot).
Keep in mind that a 50' buffer is required along all surface waters/streams except for road crossings. The base also
requires a 50' buffer along wetlands —even though the State doesn't at this time. This is for the proposed development.
I will have to get back with you on the Express review fee.

future development. This equates to a total of 12.0% impervious cover, making this a low density
SWPPP. There are 69.314 acres (6.677%) of wetlands (non -costal) within the permit boundary; however,
no wetlands fall within the new construction limits. The wetlands are delineated on the site plans. A
subsurface geotechnical investigation has been conducted by Matkin Hoover Engineering and Survey,
and a report compiled for each of the three new Training Areas. These reports are available upon
request from Megan Forthman, EIT with Parsons. Although the proposed permit boundary is located
within Onslow county and is classified as Costal Stormwater, the site does not qualify as an Area of
Environmental Concern under the Costal Area Management Act (LAMA), as the site is not on oceanfront
and does not meet any requirements of CAMA with the exception of its location within a CAMA County
(Onslow county). The entire proposed permit boundary lies within the White Oak River Basin and drains
to Bear Creek. The White Oak River Basin has no requirements for vegetated buffers. Due to the
Training Areas grading, no off -site runoff flows to the sites.
Training Area A consists of a gravel pad, an access road, and a concrete tower structure. The
existing flow from the site is 1.01 cfs. The proposed flow will increase to 1.26 cfs. This change in flow is
negligible over the size of the permit area. Training Area B consists of several ISO containers and a
penetrating wall. The ground cover within the site will be gravel. Existing flow off the site is 6.36 cfs.
After construction, the total flow will increase to 7.56 cfs, flowing at different rates off different parts of
the site. This change in flow is negligible over the size of the permit area. Training Area C consists of
several concrete block structures and walls. The ground cover will be sand. The existing flow conditions
are reduced across the site post construction. All stormwater within the proposed new construction
areas will sheet flow away from the structures off the sites. Training Area C will have drywell installed
onsite to collect some runoff.

1.0 Objective / Purpose
Determine existing and proposed condition 10 year peak design storm runoff for the project area.
2.0 Inputs/Design Condition
See Hydrology Map attached for existing and proposed site grading. The site consist of cut and fill area
with concrete tower structure. The grading is designed to sheet flow storm runoff water away from the
structure. The ground cover will be native with gravel pad and access road.
3.0 Assumptions
Hydrology:
Using NOAA Atlas 14 Point Precipitation Frequency Estimates for rainfall intensity.
We will assume the Runoff Coefficient (C) will be 0.5 for proposed and 0.4 for the existing condition. For
a typical residential development C of 0.5 is a conservative value.

1.0 Objective / Purpose
Determine existing and proposed condition 10 year peak design storm runoff for the project area.
2.0 Inputs/Design Condition
See Hydrology Map attached for existing and proposed site grading. The site consist of cut and fill area
with ISO container structures and penetrating walls. The grading is designed to sheet flow storm runoff
water away from the structures to swales and through the perimeter walls. The ground cover will be gravel.
3.0 Assumations
Hydrology:
Using NOAA Atlas 14 Point Precipitation Frequency Estimates for rainfall intensity.
We will assume the Runoff Coefficient (C) will be 0.5 for proposed and 0.4 for the existing condition
according to State of North Carolina Hydrology Manual. For a typical residential development C of 0.5 is
a conservative value for the gravel site.

Sheet Rev.
Date: 01/23/12
2.0 Inputs/Design Condition
See Hydrology Map attached for existing and proposed condition site grading. The site consists of fill area
with Sacon structures and walls. The grading is designed to sheet flow storm runoff water following the
existing drainage pattern. The ground cover will be sand.
3.0 ASSnmDtlons
Hydrology:
Using NOAA Atlas 14 Point Precipitation Frequency Estimates for rainfall intensity.
We will assume the Runoff Coefficient (C) will be 0.5. For a typical residential development C of 0.5 is a
conservative value for the sand bedding. We will also assume C value of 0.5 for existing dirt condition.

Swale Calculations:
Area D and E: V-Gutter (2:1 max. side slope):
Q = (1.49/n) A R2/3 S'n
Q=AV
V = Velocity of the water
Q = Max. Flow rate for Area D and E = 1.0 cfs
n = Manning's Roughness Coefficient (0.03 for grass, 0.02 for bare soil)
y = depth of water
A = Cross Section Area of V-gutter = 2y2
P = Wetted Perimeter = 2(5y2)1/2
R = Hydraulic Radius = A / P = 2y2 / 2(5Y)11= 0.45y
S = Slope of gutter = 0.012 max.
Q= (1.49/0.03) 2y2 (0.45y)" (0.012)1" = 1.0 cfs = 10.9 yZ (0.45y)" 3
Assume y = 0.50', Q = 1.7 cfs ; therefore y = 0.50'
Velocity: V= 1.0 / 2y2 = 1.0 / 2(0.50)2 = 2.0 ft/sec
Bare Soil (n=0.02):
Q= (1.49/0.02) 3yZ (0.47y)" (0.0120)1/2 = 1.0 cl's = 16.3 y (0.47y)2,'
Assume y = 0.43', Q = LO cfs ; therefore y = 0.43'
Velocity: V= Q/A = 1.0 / 2y2 = 1.0 / 2(0.43)2 = *2.7 ft/sec
(*Note: Gravel Bag velocity reducers will be placed during construction on the swales)
6.0 Summary
See attached Hydrology Map for the calculation results. The difference between the existing condition and
the proposed condition is 0.22 cfs for areas D and E, which is negligible. For area F, there is reduction in
storm water between proposed and existing in the amount of 0.36 cfs. The rest of the area G, I -I, I, and J
will be drained through the drywells installed on site.
At the end of drainage areas D and E, the velocity of water during the construction will be 2.7 fps. At this
stage in construction, there will be gravel bags placed on the swales to slow the storm waters. After the
grass has grown, the velocity of the storm water will be 2.0 fps.
