State Employees' Credit Union - Camden Branch
Camden County - North Carolina �r;1 `�_,(�r' n.I
August 31, 2009
The State Employees' Credit Union is proposing to construct a new facility on a 3.00 acre parcel
of land on the north side of Highway. The site is Lot 1 of the Minor Commercial Subdivision for Russell
Twiford and is zoned Highway Commercial. The site is a mostly cleared, old home site. Some trees
located around building remnants are to be removed and surcharge fill is to be placed on the site within
the next week. This work will be performed in accordance with the Letter of Approval with Modifications
for Erosion and Sedimentation Control Plan No. Camde-2010-002.
The site will be developed into primary office building complex for the credit union with two
entrances along Rosa belle Court and a third entrance along US-158. Development will consist of
constructing a building that will cover 5,720 sf (with a potential for a future addition of 1547 sf), 2,863 sf of
sidewalk, and 38,671 sf of paved parking and drive aisles. All runoff from impervious surfaces will be
collected in an underground collection system and routed to a wet detention basin. The new detention
pond will meet state requirements for 90% TSS removal and storage of the first 1.5" of runoff as well as
the county's requirement of limiting post development runoff to pre development levels during a 10-year
storm event. The pond will discharge into the existing side yard ditch on the southern property line that
ultimately drains into the wetland area some 500 feet northwest from the western property corner.
According to the Web Soil Survey, the site has three different soil types. About half of the lot is
Augusta, while the front quarter is Tomotley and the rear quarter is State. A soils evaluation dated
December 22, 2008 prepared by Soil & Environmental Consultants, PA has been attached. The report
includes a quad map, soils map, and boring logs. The evaluation for the detention pond was performed in
the left rear corner of the site where the State soils are located. According to the report, the seasonal
high water table is less than 12-24" below existing grade. With an average grade of 5', the seasonal high
water table is estimated to be between elevations 3 and 4. The high water table and low permeability
rates make wet detention the most appropriate form of storm water treatment. The permanent pool
elevation has been set at 3.5'.
Drainage Area 1 contains 1.84 acres and encompasses a majority of the site including all
proposed on -site impervious except for small portions of the driveways as they connect to the adjacent
roads. This drainage area will contain the entire building, 35,747 sf of paved parking lot, and all the
concrete sidewalk. The total impervious area will be 45,364 sf or 56.56% of the drainage area. Runoff
from the building will be collected in a French drain system and routed through the underground pipe
system. The runoff from the parking lot will sheet flow across the parking lot to various inlets. It will then
be routed through the same underground piping system as the building. The pipe system has been
designed to drain to the detention pond.
Drainage Area 2 contains the remaining 1.16 acres of the site and 1,628 sf of off -site area which
includes the pervious areas around the perimeter of the site as well as portions of the three driveways.
The pervious areas will sheet flow into existing ditches to the south and west of the site and into proposed
ditches to the north and east of the site. The only impervious surfaces in this drainage area are the short

sections of the three drives where they connect to the adjacent streets. It is not practical to route the
runoff from these areas to the pond because of the elevations and the open ditch drainage along the
roads. Runoff from the driveways connecting to Rosabelle Court will be collected in the roadside ditch
system that drains to a detention pond. The Rosabelle Court pond has been designed and submitted for
permitting, but no permit has been received at this time.
The total disturbed area for this development will not exceed 4 acres. Limits of disturbance have
been shown on the plans.

Description
Hydrologic soil groups are based on estimates of runoff potential. Soils are
assigned to one of four groups according to the rate of water infiltration when the
soils are not protected by vegetation, are thoroughly wet, and receive precipitation
from long -duration storms.
The soils in the United Slates are assigned to four groups (A, B, C, and D) and
three dual classes (A/D, B/D, and C/D). The groups are defined as follows:
Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly
wet. These consist mainly of deep, well drained to excessively drained sands or
gravelly sands. These soils have a high rate of water transmission.
Group B. Soils having a moderate infiltration rate when thoroughly wet. These
consist chiefly of moderately deep or deep, moderately well drained or well drained
soils that have moderately fine texture to moderately coarse texture. These soils
have a moderate rate of water transmission.
Group C. Soils having a slow infiltration rate when thoroughly wet. These consist
chiefly of soils having a layer that impedes the downward movement of water or
soils of moderately fine texture or fine texture. These soils have a slow rate of water
transmission.
Group D. Soils having a very slow infiltration rate (high runoff potential) when
thoroughly wet. These consist chiefly of clays that have a high shrink -swell
potential, soils that have a high water table, soils that have a claypan or clay layer
at or near the surface, and soils that are shallow over nearly impervious material.
These soils have a very slow rate of water transmission.
If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is
for drained areas and the second is for undrained areas. Only the soils that in their
natural condition are in group D are assigned to dual classes.

Re: Detailed Soils Evaluation at proposed State Employees Credit Union located adjacent
to Hwy 158 in Camden County, NC.
Dear Mr Potratz:
Soil & Environmental Consultants, PA (S&EC) performed a detailed soil evaluation at
the site mentioned above. A map was provided by the architect showing the location of
the proposed wet detention pond and where soil borings should be performed by S&EC.
At the indicated locations the following were performed. a profile description to seven
feet (or as deep as possible with hand augers), estimation of permeability, hydraulic
conductivity, and seasonal high water table based on soil color, and apparent (observed)
water table measurement (groundwater rise in auger holes). The purpose of this
evaluation was to provide you with additional information for designing a stormwater wet
detention pond. The following is a brief report of the methods utilized in this evaluation
and the results obtained.
Soil/Site Evaluation & Results
A site evaluation was performed by Walter Cole and Sarah Menser (Licensed Soil
Scientist and SSIT) to acquire the information requested. The evaluation was performed
by making hand auger borings at several locations which were located with a GPS
receiver and are shown on the attached map and identifying and recording the soil
morphological conditions at those locations in order to develop soil profile descriptions,
which are also included with this report and shown on the attached map.
Seasonal Hieh Water Table Estimation
We were able to directly measure the observed (apparent) water table at all of the boring
locations during the time of our evaluation, and also base the soil wetness on low chroma
(<2) colors in the Munsell Soil Color Chart. The seasonal high water table based on soil
color ranged from less than 12" — 24 inches from natural ground surface for all borings,
and the apparent (observed) water table at one hour was 12 inches from natural ground
level, in all of the auger holes, however, please keep in mind this is just a "snap -shot'
measurement, the reality is that the actual seasonal high water table is most likely deeper
than what is observed by soil color, especially with adjacent existing agricultural
ditching, and deeper than was is observed by apparent water table due to recent rains and
the perched water table "pushing" water up into the auger holes. The only way to
accurately determine the seasonal high water table is to do put in test wells, monitor the

site, and perform a water table assessment and this service can be provided by our fine if
requested.
The soil conditions on -site seem favorable for a wet detention pond with respect to
seasonal high water table, however the groundwater lowering effects of the existing
agricultural drainage, and the coarse loamy upper soil horizons will have to be taken into
account when deciding weather or not to incorporate a liner into the design.
Permeabilitv/hydraulic Conductivity Estimation
Most soil borings revealed a sandy loam surface horizon over a sandy clay loam subsoil
with underlying marine clay parent material. The clay subsurface horizon at all locations
was massive with respect to soil structure and extremely firm, very sticky, very plastic
with respect to soil consistency These are soil characteristics that are indicators of
expansive clay mineralogy, which forms very slowly permeable soils with estimated
hydraulic conductivity ranges from .01- 14 inches/hour.
The soil conditions on -site seem somewhat favorable for a wet detention pond with
respect to soil permeability/hydraulic conductivity as far- as the marine clay susbsurface
horizons, however the shallower coarse loamy upper soil horizons will probably require
the use of a liner to maintain water levels inside the wet pond.
Please refer to the enclosed map and soil profile descriptions for more information. All of
these estimates obtained from one or more of the following: Camden County Soil Survey
"Physical & Chemical Properties of the Soil Permeability"; Augusta, Tomotley,
Roanoke, Sununerfield Soil Series and/or USDA-NRCS (United States Department of
Agriculture - Natural Resource Conservation Service) official series description, and/or
"NRCS Field Book for Describing & Sampling Soils" the permeability estimates were
converted to conductivity on the profile description tables. No actual site specific testing
of hydraulic conductivity was performed, however this service can be provided by our
firm if requested.
Soil & Environmental Consultants, PA is pleased to be of service in this matter and we
look forward to assisting in the successful completion of the project. Please feel free to
call with any questions or comments.

Walter Cole
