RE: Seasonally High Water Table Evaluation
Tripp Cottages Phase 2
W. Third Street
Silcr City, NC
Dear Mr. Simpson:
The following discusses the seasonally high water table evaluation at the two (2) bio-
retention systems for the above referenced site.
Per the plans proved by J. Thomas Engineering, Inc. dated August 2017, Bio-retention
System BMP No. 1 will have a surface elevation of 596.0 ft. and a base elevation of
590.8 ft. Bio-retention System BMP No. 2 will have a surface elevation of 592.5 ft. and a
base elevation of 587.3 fl.
For evaluation purposes two (2) borings were conducted using a drill rig, one at each
BMP system. Figure 1 in Attachment A shows the boring locations and Attachment B
provides the boring logs.
As the soils were augered, the soil color was compared to the Munsell Soil Color Chart to
estimate seasonally high water tables and the soils were visually classified in accordance
with the Unified Soil Classification System. Any mottling or soil color with a Chroma of
3 and less is considered indicative of seasonally high water levels. Also, borings
remained open for about 1 day to measure actual groundwater depth at time of this
evaluation.
At B-1 below 6 inches of topsoil, a red (2.511-5/8) and reddish yellow (7.5YR- 6/8) silty
CLAY (CL) was present to 3.5 ft. below groundsurface. After 3.5 ft. below
groundsurface at B-1 moderately weathered mud/silt stone consisting of a brownish
yellow (10YR-6/6) and minor pale yellow (2.5 YR-7/4 clayey SILT' (ML) was
encountered. After 17 ft. below groundsurface, color altered to light olive brown (2.5
YR-3.4 with minor pale yellow (2.5YR-8/3).

Page 2
Seasonallq High %Vater'rnble Evaluation
Tripp Cottages -Phase 2
At Boring B-2, below 6 inches of topsoil, was fill extending to 6 ft below groundsurface.
The fill consisted of yellowish -red (5 YR-5/8) and brownish yellow (7.5 YR-6/8) silty
CLAY (CL), with trace of wood and asphalt fragments. After this depth, red (2.5 Y-6/6)
and yellowish brown (10 YR-5/8) silty CLAY (CL) was present to 10 ft. below
groundsurface. After 10 ft. below groundsurface moderately weathered mud/silt stone
consisting of in olive yellow (2.5 Y-6/6) clayey SILT (ML). After 13 ft., the soil color
changed to olive brown (2.5Y-4/4).
The borings remained dry after drilling and 24 to 26 hours after drilling.
According to the U.S. Department of ARrieulture Soil Survey of Chatham County, Nortlr
Carolina), the subject property is made up of Callison-Lignum complex which have a
seasonal high groundwater table ranging from 1.6 to 3.5 ft below groundsurface.
At time of drilling, the ground had been altered by past grading activities. The shallow
seasonally high groundwater levels indicated by the USDA Soil Survey arc perched water
conditions. (Water perched above the slow draining moderately weathered mud/silt stone
layer.)
Based on the soil color and measurement of the actual groundwater level, the seasonally
high water table is near 17 ft. below groundsurface or 4.8 ft. below the base of BMP 1.
For BMP 2, the seasonally high groundwater table is more than 3.3 ft. below the base of
this BMP.
We appreciate serving Simpson & Simpson on this project. Please contact us if you have
any questions.
Sincerely,
J,f/wc z T. atrick Shillington,

MAP INFORMATION
The soil surveys that comprise your AOI were mapped at
1:24,000.
Warning: Soil Map may not be valid at this scale.
Enlargement of maps beyond the scale of mapping can cause
misunderstanding of the detail of mapping and accuracy of soil
line placement. The maps do not show the small areas of
contrasting soils that could have been shown at a more detailed
scale.
Please rely on the bar scale on each map sheet for map
measurements.

Maps from the Web Soil Survey are based on the Web Mercator
projection, which preserves direction and shape but distorts
distance and area. A projection that preserves area, such as the
Albers equal-area conic projection, should be used if more
accurate calculations of distance or area are required.

PROJECT NARRATIVE
This project entails construction of 44 new condo units (22 buildings) on 12.3 acres within the Town of
Siler City's ETJ in Chatham County (Parcel ID # 82612). This development will be similar to the
adjacent Phase 1 development that exists to the east of this site. This proposed project includes the
condo buildings, private drives, playground area, water and sewer utilities, storm drainage, and
stormwater management BMPs.
The existing site is rolling terrain with proposed earthwork being closed to balanced. There are no
jurisdictional waters present within the project area. Nor is there any built -upon area proposed
within 30 feet of a perennial stream or wetland. Also, this site is not located within a designated
FEMA floodplain.
The amount of proposed built -upon area on the property is calculated to be 4.7 AC representing 38%
of the property area.
The % Built -Upon Area classifies this project as 'high density'. The site has been designed with two (2)
Bioretention BMPs to capture and treat the stormwater runoff from the new built -upon area. These
Bioretention BMPS will also help attenuate peak runoff rates of larger storm events as required by the
Town of Siler City. Stormwater discharged from the Bioretention BMPs will enter the existing storm
drainage system of the Phase 1 project. The stormwater is eventually discharged to Blood Run Creek.
