Attention: Mr. Clint Lawrence

Reference: Seasonal High Water Table Determinations
Proposed Camden Street Parking Lot— Stormwater BMP
Wingate University
Wingate, North Carolina
S&ME Project No. 1584-12-110
Dear Mr. Lawrence:
S&ME, Inc. (S&ME) has conducted Stormwater Best Management Practices (BMP) Soil
Testing per S&ME Proposal No. 1584-12-P280 dated September 26, 2012 to provide
information for a new Stormwater Management Permit Application to the North Carolina
Department of Environment and Natural Resources (NCDENR) — Division of Water
Quality (DWQ) and/or local stormwater regulatory agencies. A soil scientist
investigation was conducted to evaluate the soil properties of a proposed Stormwater
BMP area to determine suitability for stormwater management systems specifically a
proposed dry detention basin and/or sand filter. The soil scientist investigation was
conducted to evaluate seasonal high water table (SHWT) elevations below existing
ground surface (bgs).
191&iV111'i-'i *11I
Use of a dry detention basin and/or sand filter is being considered to comply with
stormwater management requirements. The use of stormwater BMP's is subject to the
suitability of site soils and regulatory approval. Regulatory guidance on requirements for
permitting of stormwater BMP's are provided in the North Carolina Division of Water
Quality — Stormwater Best Management Practices Manual (NCDENR-SW-BMP), dated
July 2007 (Revised June and September, 2009). The NCDENR-SW-BMP requires that the
SHWT must be at least 2 feet below the bottom of a dry detention basin and an open bottom
sand filter, and I foot below a closed bottom sand filter.

Stormwater BMP Soil Testing S&ME Project No. 1584-12-110
Wingate University - Proposed Stormwater BMP October 2, 2012
PROJECT BACKGROUND
The subject area evaluated is associated with one (1) proposed dry detention basin and/or
sand filter in regard to stormwater BMP's at the proposed location of the Camden Street
Parking Lot. The proposed facility is located northeast of the intersection of Camden
Road and Haskins Drive within the campus of Wingate University in Wingate, North
Carolina. Mr. Clint Lawrence, with Lawrence Associates provided Mr. Rob Willcox
with S&ME a PDF of a sketch showing the proposed Camden Street Parking Lot, along
with the proposed dry detention basin and/or sand filter location. S&ME's scope of
services consisted of evaluating the SHWT at the proposed location to a minimum depth
of eight feet bgs, or until seasonal high soil wetness conditions were encountered
(whichever is first encountered), or until auger refusal, as determined by a Licensed Soil
Scientist. The area evaluated consisted of an open grassed area (Figure 2).
An S&ME soil scientist conducted an evaluation of the soils within the proposed BMP
system, identified on the provided site map. The soil scientist evaluation was conducted
to evaluate the suitability of the soil properties relative to Stormwater Management
permitted by the NCDENR-DWQ and/or local stormwater regulatory agencies.
FINDINGS
Seasonal High Water Table (SHWT) Determination
The SHWT evaluation was performed by advancing three (3) hand auger borings to
depths ranging from 34 to 39 inches bgs within the proposed stormwater management
system area. The locations of the SHWT evaluations were approximated in the field
(Figure 2). Hand auger borings were evaluated by a Licensed Soil Scientist for evidence
of SHWT influence. This evaluation involved looking at the actual moisture content in
the soil and observing the matrix and mottle colors. Depending on the soil texture, the
soil color will indicate processes that are driven by seasonally high water table
fluctuations, such as iron reduction and oxidation and organic matter staining.
Please note that SHWT evaluations are based on secondary evidence and not on direct
groundwater level measurements. Groundwater levels fluctuate for numerous reasons
and these findings do not indicate that groundwater levels have not or will not rise above
the noted depths. The approximate SHWT test locations are identified in Figure 2, and
the approximated SI-I W"I' depths are located in Table I.

CONCLUSION
Based on auger refusal occurring at each of our hand auger boring locations, we are able
to estimate that the SHWT is greater than 39 inches bgs within the proposed stormwater
management system area.
