SYNOPSIS
This report shows the findings of a permeability study and seasonal high water
table determinations (SHWT) for the referenced parcel in Harnett County, NC.
Eight infiltration tests and eight SHWT determinations were performed.
Rapid infiltration rates (1.15 to 6.7 inches/hour) corresponded with the sandy
material. Low infiltration rates corresponded to the dense and firm sandy clay
loam material (0.87 inches/hour).
The SHWT was 36 to 72 inches below existing grade.

Drew, this is a summary of my findings:
Severson Soil Consulting, PLLC performed a permeability and seasonal high
water table (SHTW) evaluation in the proposed stormwater BMP device at the
referenced parcel (see figure 1 below). The site plan and field staked locations
provided indicated the location and depth of soil borings. At the indicated
locations, a representative soil morphology profile description was performed and
the apparent water table and SHWT were observed. The purpose of this
evaluation is to provide information for designing stormwater management
devices. The following is a brief report of the methods utilized and the results
obtained.

Methods
Site Description
The 15-acre tract in Duncan, NC was near the Wake County line. The site
was in an open farmed field that was adjacent to a railroad bed. Testing locations
were in and adjacent to staked out areas near the entrance (figure 2).

Hand auger borings were used to evaluate soil conditions (texture,
structure, depth, wetness condition, etc.) relative to the proposed stormwater
device. Soil description techniques and estimated hydraulic conductivities were
based on the NRCS Field Book for Describing and Sampling Soils, V 3.0 (2012).
In-Situ testing was performed with the Johnson Permeameter following
standard practices outlines in the instruction manual (Johnson Permeameter, LLC.
2012). The field saturated hydraulic conductivity (Kfs) value measured in the field
represents a value for a specific time and location within the tested soil. Soil
saturation and weather conditions were within acceptable parameters.

Results
Soil Descriptions
Eight soil borings were advanced on the parcel. The soils at the testing site
were derived from sandy Coastal Plain deposits and corresponded with the
Fuquay and Pocalla soil series. In general, the soil profiles contained a loamy
sand to sand surface and a sandy loam subsurface with an abrupt boundary to a
limiting layer at varying depths. This sandy clay loam textured limiting layer was
firm, dense in place, and contained prominent redoximorphic features. This layer
was present at some depth in all of the profiles. The abrupt permeability contrast
is the cause of water perching on this layer, which creates redoximorphic features.
The observation of redoximorphic features were used as SHWT indicators. A soil
profile description representative of site conditions is listed in table 1 below.

Seasonal High Water Table Depths
The depth to seasonal high water tables (SHWT) were indicated by the
redoximorphic features. Their depths ranged from (36-72 inches) within the
testing area (Figure 4). The SHWT depth corresponded with the elevation at the
site. The greater the elevation the deeper the depth to the SHWT. Additionally,
the actual water table (free water) was encountered 50" and 56" below the
existing land surface in holes 2 and 3, respectively.

The estimated permeability of this loamy sand and sandy loam material was
rapid. It was estimated to be slow in the confining layer (Btv). The following are
the results of the hydraulic testing. The tests were performed 24" above the SHWT

Summary
The measured infiltration and permeability rates were correlated to the soil
morphology. In total, the sandy material had infiltration rates that were rapid.
The test hole 8 had lower test results than tests run in similar soil textures (sand
and loamy sand) due to the area being in a trafficked area from farming activities.
The firm dense in place sandy clay loam material had low test results. All
situations corresponded with the soil morphologically.
Location SHWT Infiltration Rate
1 55" 6.7 in/hr
2 45" 3.1 in/hr
3 49" 2.25 in/hr
4 56" 5.75 in/hr
5 72" 0.87 in/hr
6 40" 6.2 in/hr
7 36" 4.78 in/hr
8 36" 1.15 in/hr
The SHWT was created by a perched water table due to the permeability contrast
between the sandy material and the firm dense layer. The hydraulic testing
utilized over 40 total gallons of water on site (see figure 13).
