Subject: RFI for SW8 081113 Camp Lejeune WWB
Mr.Pusey
Please find enclosed the amendments to the application for SW8 081113. We have addressed
your comments with the following changes and or clarifications.
1). As we discussed with the TECOM site yesterday, the C value of 2.92 represents the weir
coefficient, not related to the Rational Method. The 10 yr flow rates are from the results
generated for 10 yr flow from DWQ's supplement form, and is based on the Rational Method. So,
the flow rate is generated automatically by your supplement form, after entering the TOC, areas,
and intensity. There were no changes to the application needed to address this comment.
2.) The elevations listed on the supplement were a typo. The supplement has been corrected
and is attached. The slope, as designed, was indeed 8% and the filter strip was grass. As this
was not made more clear, we adjusted the level spreader lip elevation to allow for a 6% slope, so
as not to be on the upper end of the allowable slope for the vegetated filter.
3.) We added a note on the plans to indicate a planting rate for the vegetated filter that will
generate a thick stand of grass, coupled with the reduction in slope; I feel this will provide a
conservative velocity for the filter.
Please call me or Sean Gleason with any further questions and we will make every effort to
resolve them as quickly as possible. Bryan 864-506-1465 Sean Gleason — 919-854-6213
Thank you in advance for your assistance with the permit.

Dear Mr. Baker:
Dee Freeman
Secretary
The Wilmington Regional Office received a revised State Stormwater Management
Permit Application for BEQ Wounded Warrior Battalion TECOM Bldg on March 11,
2009. A preliminary review of that information has determined that the application is not
complete. The following information is needed to continue the stormwater review:
Concerning the 10-year design storm calculations, please show the calculations for
the peak flow rate (Q=0.67 cfs) that came from the Level Spreader, Filter Strip
Supplement. Also, please show details about how you arrived at a C value of 2.92.
Please explain the elevations listed in the Filter strip section of the Supplement.
These elevations are at the downslope base of level lip and top of bank of receiving
water. According to your plans for the filter strip area, these elevations would be 23
and 19, providing an 8% slope.
Please show a note describing the type of vegetation for the vegetated filter strip
area on the plans. For an 8% slope, only thick grass will be acceptable.
Please remember that a change to one number may have a domino effect on other
numbers. Please check all plans, calculations and forms and make changes as needed.
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 April 10,
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.
If you need additional time to submit the information, please mail, email 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 of NCGS 143-215.1 and
is subject to enforcement action pursuant to NCGS 143-215.6A.

IDENTIFY PROJECT INVOLVEMENT
THIS PROJECT IS A PART OF THE WHITE OAK RIVER BASIN, AND IS CURRENTLY
NOT SUBJECT TO ANY BUFFER RULES. THE SITE IS APPROXIMATELY 2,700 FEET FROM
THE NEW RIVER APPROXIMATELY 3.5 MILES FROM THE CAMP LEJEUNE MAIN GATE
THE PROPOSED PROJECT STORMWATER PLAN WILL MEET THE REQUIREMENTS
OF RETAINING THE RUNOFF VOLUME THE 1.5 INCH RAINFALL EVENT PER THE
REQUIREMENTS BY THE STATE AS REFERENCED FROM THE DWQ STORMWATER
MANUAL, JULY 2007. ONE INFILTRATION BASIN IS USED TO TREAT ONE DRAINAGE
AREAS AND ONE LEVEL SPREADER TREATS THE BYPASS FLOW. THIS PROJECT IS NOT
WITHIN 0.5 MILES OF SA WATERS, NOR WITH 575 FEET OF ORW WATERS. AND THUS
INFILTRATION DEVICES ARE NOT REQUIRED BY DWQ. THE TREATMENT VOLUME
PROVIDED AS WELL AS THE USE OF SWALES AND ADEQUATE INFILTRATION CAPACITY
WILL PROVIDE A POST DEVELOPMENT PEAK FLOW RATE THAT IS LESS THAN THE PRE -
DEVELOPMENT CONDITION, PER THE JULY 2007 START DATE FOR MEETING PHASE II
REQUIREMENTS. HYDROCAD MODELS BASES ON TR-55 METHODS WERE USED TO
VALIDATE THE COMPLETE CAPTURE OF THE RUNOFF DIFFERENCE FOR THE 1.5" TYPE
III - 24 HR. STORM,
STORMWATER DESIGN PARAMETERS
THE INFILTRATION BASINS ARE BASED ON THE FOLLOWING PARAMETERS OR
OBJECTIVES:
• PROVIDE 85% TSS REMOVAL
• PROTECT THE VALUE OF THE RECEIVING WATER RESOURCE
• 1.5" RAINFALL FOR BASIN STORAGE SIZING
• THE I YR RAINFALL FOR OUTLET STRUCTURE AND ROUTING DESIGN TO
MAINTAIN A POST DEVELOPMENT PEAK FLOW THAT IS LESS THAN PRE -
DEVELOPMENT PEAK FLOW
• RATIO OF IMPERVIOUS SURFACE TO THE TOTAL AREA OF THE DRAINAGE AREA
• EXCEED A MINIMUM OF 2.0' CLEARANCE FROM THE SEASONAL HIGH WATER
TABLE

• RAINFALL EXCEEDING THE DESIGN STORM WILL BYPASS THE BASINS AND FLOW
THROUGH A MINIMUM OF 50' LONG VEGETATED FILTER
DISCUSSION OF TREATMENT MEASURES
THE PROPOSED TREATMENT IS TO USE ONE INFILTRATION BASIN TO MEET THE
TSS AND PEAK FLOW REQUIREMENTS SET FORTH BY DWp. THE SOILS OF THE
PROJECT SITE ARE APPROPRIATE SOILS FOR INFILTRATION AND THE SEASONAL HIGH
WATER TABLE AT THE SITE WILL ALLOW CONSTRUCTION OF THE BASIN WITH AT LEAST
A 2' OF CLEARANCE. BYPASS DEVICES ARE PROVIDED TO ALLOW ANY RUNOFF VOLUME
THAT EXCEEDS THE DESIGN STORAGE VOLUME TO BE ROUTED TO A LEVEL SPREADER
WITH A VEGETATED FILTER STRIP. THE LEVEL SPREADER LENGTH IS DESIGNED TO
HANDLE THE 10 YR PEAK RUNOFF RATE, SO NO BYPASS OF THE FILTER IS NECESSARY.
PHASE II REQUIREMENTS ARE MET BY USING A GRASSED SWALE TO COLLECT
SHEET FLOW FROM THE IMPERVIOUS AREAS AND BY THE INFILTRATION AND STORAGE
VOLUME PROVIDED IN EACH BASIN.
CONCLUSION
THIS STORMWATER MANAGEMENT PLAN REPRESENTS AN ENVIRONMENTALLY
SENSITIVE AND EFFECTIVE PLAN FOR UTILIZING THE PROPOSED STORMWATER
TREATMENTS TO ACCOMMODATE THE INCREASED RUNOFF OF THE PROPOSED SITE
DEVELOPMENT.

have been discarded or recycled, as appropriate. Please address the following noted
deficiencies and provide the requested information:
1. Sealed design calculations.
2. Provide 4 inch of clean sand on the plan detail and the supplement.
3. Delineate wetlands on the plans, sealed by PE, or state on the plans that none exist on
the project area.
4. If you resubmit the requested items within 24 hours, the package will be accepted and
you will keep your place in line for review. Otherwise, the application fee will be
returned and will require resubmittal of all required documents.
5. Please reference the application review checklist to help in completing the application
package. The checklist is on the website at:

Checklist for Completeness Review of Stormwater Applications
Each application for which a "Completeness Review' is needed will have this checklist printed on
yellow paper to distinguish it from other applications to be reviewed.
❑ Read the narrative and application to determine the type of project, i.e., residential vs.
commercial, subdivision vs. single lot, high density, low density, offsite, redevelopment, and
determine what documentation needs to be provided.
❑ Make sure that all required forms, supplements, O&M's, deed restrictions, signature
authorizations, etc., are included and contain original signatures.
❑ If low density, make sure the BUA calculations include any common areas, clubhouse areas,
etc., and do a quick math check for addition errors.
❑ Do a quick consistency check of the numbers used in the calculations vs. the numbers
reported on the application. For multiple BMP's pick one or two to check.
❑ Ownership issues? Make sure the correct person has signed the application. If it's a
corporation or LLC, print off the NCSOS information sheet and latest annual report. Make
sure the person who signed is listed on the annual report with his/her correct title, or make
sure a signature authorization letter has been provided.
❑ Make sure 2 sets of plans have been submitted, and that they include grading, layout (with
dimensions for all proposed BUA) and details.
e Are the Wetlands delineated on the plans? Y N By whom?
If the project drains to SA waters, make sure a USGS topo map with the site, the receiving
waters and the ''/z mile radius clearly shown to scale, is provided.
❑ For high density projects, make sure the correct design storm is used, based on the receiving
stream classification and the projects proximity to SA waters.
❑ Make sure appropriate details are provided such as roads, cul-de-sacs, curbing, sidewalk,
BMP's, level spreaders, vegetated filter strips, curb outlet swales, etc. Two of the most
common errors are that sidewalk is indicated on the plans, but not included in the BUA calcs
or shown with the road detail, and the road width used in the BUA calculations is less than
that shown on the road detail.
Are there any issues within the 575 ft ORW AEC?
If high density, make sure the plans and calculations are signed, sealed and dated.
If the project involves the subdivision of property or has outparcels, make sure a copy of the
Proposed Declaration of Covenants and Restrictions in legal format with all required
statements is provided, or that the appropriate standard deed restriction template, signed and
notarized, is provided.
❑ Make sure that a Soils Report for all projects is provided, to determine if the required
separation to the SHWT is provided.
8 For multiple HD systems & curb outlet swales, make sure a drainage area map is provided.
If the application is substantially incomplete, give the entire file with the check to admin (Jo
Casmer) to be returned to the applicant. Jo will keep copies of the return letters, application &
check.
❑ If the application lacks only a few minor items such that it can be made complete within 24
hours, you can email the consultant and request the information. Hold onto the package for
24 hours. If the information isn't received within 24 hours, give the application to Jo to return.
For Offsite projects:
The Designer's Certification for the offsite system has been submitted.
The deed restrictions have been recorded and a copy submitted.
The offsite system is in compliance with its permit.
Make sure the lot size hasn't changed from what was approved under the Master Plan and
that the correct lot number is referenced on the supplement form.
For Infiltration projects:
Soils report to determine SHWT, soil type and expected infiltration rate is provided.
Has Vincent conducted the site investigation? If Yes, date?
For infiltration projects, the maximum 2 acre inches of volume in any single system has not
been exceeded.
For Wet Ponds projects:
❑ Permanent pool to be located no lower than 6" below the estimated SHWT. Otherwise, the
incoming groundwater must be quantified and evaluated; the storage volume must be
verified; and the outlet needs to be evaluated for free drainage to the receiving waters under
SHWT conditions.

INTRODUCTION
The Marine Corps Base at Camp Lejeune plans an expansion at the Wounded Warrior Barracks.
As part of this expansion, several stormwater infiltration basins are being considered to infiltrate
runoff from adjacent impervious surfaces. As part of the application process, a soils
investigation detailing soil type, infiltration rate, and depth to seasonal high water table is
required. The Catena Group, Inc (TCG) has been retained to perform the soil investigations.
INVESTIGATION METHODOLOGY
Prior to the field investigation, the Onslow County Soil Survey was referenced to get an
overview of the possible soil series located in the study area. Around the site, there are three
mapped units (Table 1). Figure t presents the mapped soil series and the general locations of the
proposed infiltration basins where soil borings and infiltration tests were performed.

The field investigation was performed on October 16 and 21, 2008. Soil borings were made with
a hand -turned auger in the vicinity of the proposed infiltration basins. Observations of the
landscape (slope, drainage patterns, past use, etc.) as well as soil properties (depth, texture,
structure, seasonal wetness, restrictive horizons, etc.) to a depth >_ 60 inches, when possible, were
recorded. Soil color was determined with a Munsell Soil Color Chart.
The rate of water entry into a soil is referred to as the infiltration rate. The infiltration rate into a
soil decreases with time mainly due to an increase in the soil water content and a decrease in the
hydraulic gradient. As infiltration continues, the rate of water entry into the soil reaches a
constant value (steady state condition), which is considered to be the same as the saturated
hydraulic conductivity (KSAT) of the soil. The KSAT was measured in the field and used to
characterize the infiltration rate for the proposed infiltration basin.
KSAT measurements were performed at the proposed infiltration basin using a constant -head
permeameter (Amoozemeter). Before any readings were recorded, the Amoozemeter was
allowed to equilibrate, typically 15-20 minutes.
Based on conversations with the designer of the proposed infiltration basins, construction of the
basin would remove approximately 6 inches of topsoil. As such, the KSAT measurements were
performed around a depth of 12 inches in order to estimate the infiltration rate at the new soil
surface. The rate was also measured at an approximate 2-foot depth to ensure that there was a large
enough window to allow lateral flow away from the basins.

RESULTS
Soil Type
All of the soil was in a natural state and with fairly similar horizons except for Site 4, which had
8 inches of fill material and the structure of subsurface horizons appears to have been adversely
altered due to some surrounding cut and fill.
Table 2 presents each boring with a soil series determination. Determination of soil series was
made through a comparison of soil boring descriptions to the Natural Resources Conservation
Service (MRCS) Official Series Description (OSD) for the soil series that were mapped by the
NRCS for this site.
Depth to Seasonal High Water Table
The depth to the seasonal high water table (SHWT) was noted at each boring based on
redoximorphic features, the presence of saturated soil, and best professional judgment.

Infiltration Rate
Saturated hydraulic conductivity tests were performed at each of the proposed infiltration basin
sites and the results for each test are shown below in Table 3. Since soil is inherently non -
homogeneous, field tests can often misrepresent the aerial hydraulic conductivity of a soil. In
particular, field tests underestimate the saturated hydraulic conductivity of clayey soil and
overestimate it in sandy soils. As a result of this misrepresentation, a "moderation factor" is
suggested to convert point saturated hydraulic conductivity to aerial saturated hydraulic
conductivity for each proposed infiltration basin. Since the soil is typically fine sand or loamy
sand, a moderation factor of 0.75 was used to correct for the potential of overestimating the
infiltration rate.
Table 3 presents the saturated hydraulic conductivity geometric mean for each infiltration basin
as well as a moderation factor to get an area infiltration rate for each proposed infiltration basin.

As shown in Table 3, all proposed basin have an infiltration rate that is greater than the required
minimum of 0.52 inch/hour.
CONCLUSIONS
The findings presented herein represent TCG's professional opinion based on our site and soils
evaluation. This report is provided to assist in the application for the infiltration basin by
providing the soil information. North Carolina DWQ must issue the final permit. Any
concurrence with the findings in this report would be made at that time.
