Stormwater Management Narrative
P4041Ambulatory Care Center/Dental Clinic Replacement
Hadnot Point
Camp Lejeune, NC
This project consists of the construction of a new medical/dental clinic in the Hadnot
Point area of Camp Lejeune. The medical/dental clinic will be located on a site that is
now developed with an old and relatively large building and parking area that will be
demolished. Across "I" street from the new clinic is a wooded area and two old
buildings that will also be demolished. A parking lot is proposed in this area. This
project is a stormwater redevelopment project that provides equal or better stormwater
controls.
A summary of the built -upon area associated with this project is as follows:
• Existing BUA demolition at new clinic site = 94,474 SF
• Existing BUA demolition at new parking lot site = 20,320 SF
• Total existing BUA demolition=114,794 SF
A summary of the replacement BUA is as follows:
• New medical/dental clinic = 80,201 SF
• New parking lot site = 31,505 SF
• Permeable interlocking concrete pavers = 8,161 SF (Count as 0 SF)
• Plastic turf reinforcing grid = 2,776 SF (considered as BUA)
Total new BUA = 114,482 SF
There would be a net impervious area loss of 114,482 - 114,794 — -312 SF. The site and
the drainage patterns would be designed to provide equal or better stormwater controls by
features such as disconnected impervious surfaces, lightly sloped yard drainage areas and
drainage swales. The 8,161 SF of pervious pavers are designed to also catch the flow
from 4,413 SF of impervious surface (asphalt). The pervious base material consists of 10
inch thick stone and is sized to capture in excess of the runoff associated with the 2.0 inch
rainfall event as opposed to the required 1.5 inch rainfall event.
The existing drainage conditions at the portion of the site where the buildings will be
demolished consists of flow across grass lawns around the building areas with eventual
discharge into a stormwater collection and piping system. The existing parking area has
stormwater catch basins connected with stormwater piping. The new parking area across
from the clinic is being built in a wooded area that currently has sheet flow runoff
conditions.

The site will be using permeable interlocking concrete pavers in order to be able to use
the redevelopment option and complete the project with no net gain of impervious area.
The pervious paver surfaces are broken down into two drainage areas.
Pervious paver drainage area 1 (D.A. #2) is 1,820 SF in size. 1,501 SF of that surface is
pervious pavers. The drawdown time for the 2.0 inch storm is 3 hours.
Pervious paver drainage area 2 (D.A. #3) is 10,754 SF in size. 6,660 SF of that surface is
pervious pavers. The drawdown time for the 2.0 inch storm is 4 hours.
The pervious paver areas will have a perforated underdrain in order to dewater the SCMs
for maintenance. The valve will be in the normally locked position so that the pavers can
function as infiltration areas.
The site drains to an unnamed tributary of the New River which is classified as SQNSW
(Index #19-(15.5)). All work is located greater than fifty feet from surface waters
including the stream feature shown on the soils map. At the request of the stormwater
section, a stream call is being requested on this feature. There are not any wetlands on
the site. There are not any known historic sites on the property.
The soil on the site is classified as Baymeade by the Onslow County Soil Survey.
Baymeade is described as a fine sand at the depths to be disturbed by this project. The
soils report prepared by ECS reports an infiltration rate of 4.41 inches/hour and a
seasonal high water table depth of greater than 100 inches (8.33 feet). The elevation at
the sample point was 17.5' and corresponds to a seasonal high water table elevation of 9.2
feet.
A sedimentation and erosion control permit is being obtained. The site will be stabilized
with centipede sod. There are not any other anticipated environmental permits.

Reference: Report of Seasonal High Water Table Estimation and Infiltration Testing
Medical/Dental Clinic — Hadnot Point
Camp Lejeune, Onslow County, North Carolina
ECS Project No. 49.3153
Dear Mr. Parker:
ECS Carolinas, LLP (ECS) recently conducted a seasonal high water table (SHWT) estimation
and infiltration testing within the proposed stormwater best management practice (BMP) area(s)
off of H Street on Camp Lejeune, Onslow County, North Carolina. This letter, with attachments,
is the report of our testing.
Field Testing
On May 3, 2017, ECS conducted an exploration of the subsurface soil and groundwater
conditions at two requested locations shown on the attached Boring Location Plan (Figure 1).
ECS located the borings using GPS equipment. The purpose of this exploration was to obtain
subsurface information of the in situ soils for the stormwater BMP area(s). ECS explored the
subsurface soil and groundwater conditions by advancing one hand auger boring into the
existing ground surface at each of the requested boring locations. ECS visually classified the
subsurface soils and obtained representative samples of each soil type encountered. ECS also
recorded the SHWT and groundwater elevation observed at the time of the hand auger borings.
The attached Infiltration Testing Form provides a summary of the subsurface conditions
encountered at the hand auger boring locations.
The SHWT and groundwater elevation was estimated at the boring locations below the existing
grade elevation. A summary of the findings are as follows:
Location
slim
Groundwater
B-1
100 inches
>120 inches
B-2
100 inches
>120 inches
ECS has conducted two infiltration tests utilizing a compact constant head permeameter near
the hand auger borings in order to estimate the infiltration rate for the subsurface soils. The
infiltration tests were conducted at the estimated subgrade elevation for a pervious concrete
parking lot. Tests in clayey conditions are conducted and calculated up to 30 minute intervals.
If an exact hydraulic conductivity is necessary for these locations, then ECS recommends
collecting samples by advancing Shelby tubes and performing laboratory permeability testing.
SHWT and groundwater elevations may vary within the proposed site due to changes in
elevation and subsurface conditions.

Dear Christine :
Enclosed please find the following for the above -referenced project:
• Two sets of revised plans showing stormwater permit boundary (last 2
sheets in set) and permeable pavement elevation data.
• Two copies of USGS map with lat/lon.
• Description of SCM dewatering added to supplement and revised
narrative.
• Information on SHWT elevation added to supplement and narrative.
• Added project stormwater program to supplement.
• Printed SCMs at one per page.
We moved the stormwater boundary in to make it smaller to agree with the actual
numbers. The areas that were omitted contained no existing or new BUA, so the
calculations did not change.
Should you have any questions, please do not hesitate to give me a call.

Dear Mr. Paul:
The Wilmington Regional Office received and accepted an Express State Stormwater Management Permit
Application for the subject project on March 27, 2018. A preliminary in-depth review of that information
has determined that the application is not complete and that additional information is needed. To
continue the review, please provide the following additional information:
✓1. 15A NCAC 02H.1042(2)(d): Please provide a copy of the USGS map identifying the project
location and the GPS coordinates for the project.
V2. 15A NCAC 02H.1042(2)(g)(ii): Please provide a dimensioned project or project phase boundary
with bearings and distances.
3. 15A NCAC 02H.1042(2)(h)(i): Please provide elevations for the proposed SCMs on the plans
including the top of the subgrade, the top of the aggregate, and the top of the pavement.
✓4. 15A NCAC 02H.1050(6): The supplements indicate that another type of method will be provided
to dewater the SCM for maintenance. Please describe the proposed method at the bottom of the
supplement under the additional information section.
/5. 15A NCAC 02H.1055(1): Please provide the existing ground elevation at the location of the soil
boring to support the identified seasonal high water table (SHWT) elevation.
V,K" Section C.5 of the Stormwater Control Measure Credit Document and Chapter C-5 of the
Stormwater Design Manual: As discussed in the submittal meeting, if it is desired to consider the
permeable pavement as 100% pervious, the permeable pavement must be designed to infiltrate.
The provided perforated storm drain provides an opportunity for the runoff entering the
permeable pavement to bypass the infiltration process. In order to obtain the 100% BUA credit,
please either remove this perforated storm drain, install a locking cap, or propose an outlet
structure similar to Figure 2 on Page 3 of Chapter C-5 of the Stormwater Design Manual.
7. 15A NCAC 02H.1042(3)(b):
tea. Under the "Compliance with the Applicable Stormwater Program" section of the
supplement, please identify the stormwater program that applies to this project.
Please provide the supplements such that they are of a readable font size. One option to
force each supplement to print on a separate page is to change the scaling from "fit sheet
on one page" to "fit all columns on one page" under the print options.
8. 15A NCAC 02H.1042(2): Please email the supplement form to [e-mail] so that
it can be preserved electronically per the regulatory requirements.

now developed with an old and relatively'large building and parking «rea that t rill 1,e
demolished. Across "L" street from the new clinic is a wooded area. and two old
buildings that will also be demolished. A puking lot is proposed in this area..
A suri-nary of the built -upon area associated with this project is as follows:
Existing I :UA uernolitior. at new clinic site = 94,474 SF
Existing E`UA demolition at new par'xing iot site 20,320 SF
Total existing BUA demolition=114,794 SF
A samma-y of the replacement BI1A is as :fol or,s:
• New medicalid.catal clinic = 80,201 SF
■ New parking lot site = 31,41.9 SF
■ Permeable intcrlocking concrete pavers 8,247 SF (Count as 0 SF)
■ Plastic turf reinforcing grid 2,776 SF
Total new BUA - 114,396 SF
1"here would be a net impervious arwa loss of i 14,396 - 1.14,794 -398 SF. The site and
the drainage patterns would be designed to provide equal or better stormwater controls by
LID features such as disconnected impervious suri"aces, lightly sloped yard drainage areas
and drainage swales.
The site drains to an urinated tributary of the New River v�,hich is classified m SC;NSW
(Index #19-(15.5)). Al; work is located greater than fifty feet from surface waters
including the stream feature shown on the soils map. There are not any wetlands on the
site. There are not any known historic sites on !:he property.
The soil on the site is classified as Baymeade by the 4nslow County Soil Survey.
Baymeade is described as a fine sand at the depths to be aistarbed by this project.
A sedfi entation and erosion control permit is being obtairicd. There are not any other
anticipated environmental permits.

This project consists of the construction of a new medicaUdenUd clinic in the Hadnot

now developed with an old and relatively large building and parting area that will be
demolished. Across "L" street from the new clinic is a wooded area and two old

• Existing BUA demolition at new parking lot site = 20,320 Sr
• Total existing BUA demolition = 114,794 SF
A summary of the replacement BUA is as follows:
* New medical/dental clinic = 80,201 SF
• New parking lot site = 31,419 SF
• Permeable interlocking concrete pavers U47 SF (Count as 0 SF)
* Plastic turf reinforcing grid = 2,776 SF
Total new BUA=114,396 SF
There would be a net impervious area loss of 114,396-114,794 -398 SF. The site and
the drainage patterns would be designed to provide equal or better stor.:nwater controls by
LID features such as disconnected impervious surfaces, lightly sloped yard drainage areas
and drainage swales.
The site will be using permeable interlocking concrete pavers and plastic turf grid
reinforcing in order to be able to use the redevelopment option and complete the project
with no net gain of impervious area. The purpose of the SCM's is not to circumvent the
rules. The SCM's will be constructed and maintained in accordance with the NC DEQ
Coastal Ston nwater Rules.
The site drains to an unnamed tributary of the New River which is classified as SQNSW
(Index #19-(15.5)). All work is located greater than fifty feet from surface waters
including the stream feature shown on the soils map. At the request of the storm.water
section, a stream. call is being requested on this feature. There are not any wetlands on
the site. There are not any known historic sites on the property.
The soil on the site is classified as Baymeade by the Orslow County Soil Survey.
Baymeade is described as a fine sand at the depths to be.disturbed by this project.

Express request for P4041 - Hadnot Point
Joe / Beth,
I took a look at the express request for the proposed redevelopment for the Ambulatory Care Center / Dental Clinic at
Hadnot Point. The narrative discusses using permeable pavement to stay beneath the predeveloped built -upon
area. However, the BUA credits from infiltrating permeable pavement cannot be used to create an exemption from the
rules (refer to the beginning of the permeable pavement chapter of the design manual). A review of the pavement
design is required to ensure the MDC are met and a permit is required to ensure the requirements will continue to be
met. The use of permeable pavement would require this project to be considered a high density project. If you still wish
to use permeable pavement, please update the narrative and express request to reflect this being both a high density
project using permeable pavement and a redevelopment exemption.
Also, in reviewing my notes from the scoping meeting on February 16" of this year, I recommended that the source of
the surface waters be confirmed. Have you contacted DWR to confirm the extent of the surface waters near this site?

Medical/Dental Clinic Replacement
"L" Street
Camp Lejeune, NC
This project consists of the construction of a new medical/dental clinic in the Hadnot
Point area of Camp Lejeune. The medical/dental clinic will be located on a site that is
now developed with an old and relatively large building and parking area that will be
demolished. Across "L" street from the new clinic is a wooded area and two old
buildings that will also be demolished. A parking lot is proposed in this area. The
project also includes the demolitionof the old clinic (Bldg. 460) and site improvements
all in this same contract that are located approximately 1,800 feet from the new clinic
site. The old clinic site is located in the same watershed as all of the new work.
Redevelopment credit is being requested for this demolition work.
A summary of the built -upon area associated with this project is as follows:
«, Demolition at new clinic site = 74,179 SF
a Demolition at old clinic (Bldg. 460) site = 47,472 SF
Construction at new clinic site (Bldg. & parking) = 81,943 SF
There would be a net impervious area loss of 39,708 SF. The site and the drainage
patterns would be designed to provide equal or better stormwater controls.
There would likely be some other Navy imposed stormwater treatment measures
associated with the LEED and LID requirements.
The site drains to an unnamed tributary of the New River which is classified as SC;NSW
(Index #19-(15.5)). All work is located greater than fifty feet from surface waters
including, the stream feature shown on the soils map. There are not any wetlands on the
site. There are not any known historic sites on the property.
The soil on the site is classified as Baymeade by the Onslow County Soil Survey.
Baymeade is described as a fine sand at the depths to be disturbed by this project.
A sedimentation and erosion control permit would be obtained. There are not any other
anticipated environmental permits.
