NOVA Project Number 10705-2021005
Dear Mr. Boyett:
We have completed the requested Seasonal High Groundwater Table (SHWT) Determinations for the
above referenced project. For this determination we have teamed with Three Oaks Engineering.
The field investigation for this study was completed on March 7, 2021 and consisted of five (5) hand
auger borings for SHWT determinations within four (4) stormwater control measures (SCMs). The
SHWT borings were advanced to a target depth of approximately five (5) feet below the existing grades;
however, some borings were advanced deeper. Readings SHWT-1 and SHWT-4 did not reach the
proposed target depth (5') due to auger refusal (rock) at 59" and 51" below ground surface,
respectively.
The attached report, prepared by Three Oaks Engineering, contains the results of the field exploration.
To summarize, soil characteristics indicative of a SHWT (Hayesville Soil Series) were not observed in
any of the five (5) borings performed within the four (4) SCMs during the investigation. The attached
report should be reviewed for additional details and information regarding testing procedures,
locations, and results.
We appreciate the opportunity to continue to be of service on this project. Please contact us if you
have any questions or if we may be of further assistance.
Sincerely,
NOVA Engineering and Environmental, Inc.

INTRODUCTION
NOVA is investigating the construction of four (4) stormwater control measures (SCMs) within the
Ferncliff project site located at the end of Ferncliff Park Drive in Fletcher, Henderson County, NC.
The SCMs are being considered to collect and treat runoff from impervious surfaces. As part of the
application process, a soils investigation detailing soil type and depth to the seasonal high water table
(SHWT) at five (5) locations is required. Three Oaks Engineering (Three Oaks) has been retained to
perform the soil investigation.
INVESTIGATION METHODOLOGY
The Web Soil Survey was referenced prior to the field investigation to get an overview of the
possible soil series located at the SCM location. The Hayesville soil series is mapped at the proposed
SCM locations (Figure 1). Information for these series is listed in Table 1.

The field investigation was performed on March 7, 2021, by Evan T. Morgan, LSS utilizing a hand -
turned auger. The boring locations were staked with a target depth of 5-feet. The site was wooded.
Observations of the landscape (slope, drainage patterns, etc.) as well as soil properties (depth,
texture, structure, color, seasonal wetness, restrictive horizons, etc.) were recorded. Soil profiles were
described per the USDA-NRCS, Field Book for Describing and Sampling Soils, version 3.0. Soil
color was determined with a Munsell Soil Color Chart.
RESULTS
A soil series determination was made by comparing the soil boring profile description to the NRCS
Official Series Description (OSD) and the results listed in Table 2.
A SHWT was not observed at any of the boring locations. The target depth was not achieved at
boring SHWT-1 (59") and SHWT-4 (51") due to auger refusal from subsurface rock. All soil borings
were representative of the Hayesville soil series. Full soil profile descriptions and a key to profile
abbreviations are attached. The NRCS OSD for the Hayesville soil series is appended.

CONCLUSIONS
The findings presented herein represent Three Oaks' professional opinion based on our soil
investigation. A SHWT was not observed at any of the borings. The target depth of 5-feet was not
achieved at SHWT-1 and SHWT-4 due to shallower auger refusal.
Due to the inherent variability of soils to change over short distances, the soil profile description
presented in this report may not be representative of the entire soil system of the SCM footprint. This
report is provided to assist in the application for the SCMs by providing the soil information. The
permitting agency must issue the final permit. Any concurrence with the findings in this report would
be made at that time.

SOIL TEXTURE
Soil texture is the numerical proportion (weight percentage)
of the sand, silt, and clay separates in the fine -earth fraction
(52 mm). Sall texture is field estimated by hand or lab measureal.
by hydrometer or pipette and placed within the textural triangle to
obtain Texture Class.
Re—c! the Texture Class; e.g., bam; or Subclass; e.g., fine
sandy loam; or choose a Term in Lieu of Texture; e.g., gravel. If
appropriate, use a Texture Class Modifier; e.g „gravelly loam,
NOTE. Soil Texture includes only thefine-earth fraction (52 mni
"Whole -mil Particle-Slze Distribution" includes the fine -earth
Fraction (52 mm, wt %) and manse fragments (>2 mm). (NOTE:
For fragments >76 mm in diameter, visually estimate the volume
percent, which is then converted to a weight basis using the
estimated particle density [pit] and bulk density [BJ.)

CONSISTENCE
Consistence is the degree and kind of cohesion and adhesion that
soil exhibits and/or the resistance of soil to deformation or rupture
under an applied stress. Soil -water state strongly influences
consistence. Field evaluations of consistence include: Rupture
Resistance (Blocks, Peds, and Clods; or Surface Crusts and
Plates), Manner of Failure (Brittleness, Fluidity, Smeariness),
Stickiness, Plasticity, and Penetration Resistance. Historically,
consistence applied to dry, moist, or wet soil as observed in the
field. Wet consistence evaluated stickiness and plasticity. Rupture
Resistance now applies to dry soils and to soils in a water state
from moist through wet. Stickiness and Plasticity of soil are
independent evaluations.
RUPTURE RESISTANCE —A measure of the strength of soil to
withstand an applied stress. Separate estimates of Rupture
Resistance are made for Blocks/Peds/Clods and for Surface
Crusts and Plates of soil. Block -shaped specimens should be
approximately 2.8 cm across. If 2.8-cm cubes (e.g., = 2.5-3.1 cm,
or I inch) are not obtainable, use the following equation and the
table below to calculate the stress at failure: [(2.8 cm/cube length
Chl X estimated stress (N) at failure)]; e.g., for a 5.6-cm cube
[(2.8/5.6)2 X 20 NJ = 5 N - Soft Class. Plate -shaped specimens
(surface crusts or platy structure) should be approximately
1.0-1.5 cm long by 0.5 cm thick (or the thickness of occurrence, if
<0.5 cm thick).
RUPTURE RESISTANCE FOR:
Blocks, Peds, and Clods —Estimate the class by the force required
to rupture (break) a soil unit. Select the column for the appropriate
soil water state (dry vs. moist) and/or the Cementation column, if
applicable.

HAYESVILLE SERIES
The Hayesville series consists of very deep, well drained soils on gently sloping to very steep ridges and side
slopes of the Southern Appalachian Mountains. They most commonly formed in residuum weathered from
igneous and high-grade metamorphic rocks such as granite, granodiorite, mica gneiss and schist; but in some
places formed from thickly -bedded metagraywacke and metasandstone. On steeper slopes the upper part of some
pedons may have some colluvial influence. Mean annual air temperature is 55 degrees F., and average annual
precipitation is about 56 inches near the type location. Slopes range from 2 to 60 percent.
TAXONOMIC CLASS: Fine, kaolinitic, mesic Typic Kanhapludults

TYPE LOCATION: Clay County, North Carolina; 2.5 miles southeast of Hayesville, on Swain Road in road
cut on north side of road.
RANGE IN CHARACTERISTICS: Solum thickness is 30 to 60 inches. Depth to bedrock is greater than 60
inches and ranges to more than 10 feet. Content of rock fragments ranges from 0 to 40 percent by volume in the
A and E horizons and 0 to 15 percent in the B and C horizons. Rock fragments are commonly pebbles, cobbles,
or stones, but may include charmers or flagstones. Reaction is extremely acid to moderately acid unless limed.
Limed soils are typically slightly acid to neutral in the upper part. Flakes of mica range from none to common in
the A and B horizons above a depth of 40 inches, and from none to many in the B and C horizons below 40
inches.
The A or Ap horizon has hue of 5YR to 1 OYR, value of 3 to 6, and chroma of 2 to 6. Where the value is less
than 3, it is less than 7 inches thick. The A horizon is loam, fine sandy loam, sandy loam, or very fine sandy
loam in the fine -earth fraction, or eroded pedons are sandy clay loam or clay loam.
The E horizon, where present, has hue of 7.5YR or IOYR, value of 4 to 6, and chroma of 3 to 8. It is loam, fine
sandy loam, sandy loam, or very fine sandy loam in the fine -earth fraction.
The BA horizon, where present, has hue of 2.5YR to 1 OYR, value of 4 to 6, and chroma of 4 to 8. Texture is
loam, clay loam, or sandy clay loam.
The Bt horizon has hue of 1 OR to 5YR, value of 4 or 5, and chroma of 6 or 8. Mottles, if they occur, are in
shades of red, yellow, or brown. Texture is clay or clay loam.
The BC or CB horizon, where present, has hue of 1 OR to 7.5YR, value of 4 to 6, and chroma of 6 or 8. Mottles,
if they occur, are in shades of red, yellow, or brown. Texture is sandy clay loam, clay loam, or loam.
The C horizon is saprolite that is sandy clay loam, loam, sandy loam, or fine sandy loam. It is variable in color.
COMPETING SERIES: This is the only other known series in this family. Bradson, Brevard, Braddock,
Clifton, Evard, Fannin, and Nantahala (tentative) soils are in closely related families. Bradson and Braddock
soils have water worn coarse fragments. In addition, the Braddock soils have mixed mineralogy. Brevard, Evard,
and Fannin soils have less than 35 percent clay in the control section. Nantahala (tentative) and Clifton soils
have mixed mineralogy.
Note: Competing series have not been updated since most of these will also require reclassification using the 7th
Edition of Keys to Soil Taxonomy (1996).
GEOGRAPHIC SETTING: The Hayesville soils are on gently sloping to very steep ridges and side slopes in
the intermountain plateaus, low rolling hills, and valleys of the southern Appalachian Mountains. Slopes range
from 2 to 60 percent. Elevation ranges from 1400 to 4000 feet. The soils most commonly formed in residuum
from igneous and high-grade metamorphic rocks such as granite, granodiorite, mica gneiss and schist; but in
some places formed from thickly -bedded metagraywacke and metasandstone. There may be some colluvial
influence on steep slopes. Mean annual air temperature is ranges from 46 to 57 degrees F., and average annual
precipitation ranges from about 40 to 60 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: In addition to the similar Braddock, Clifton, Evard, and
Fannin soils these include the Brevard, Cullasaja, Saunook, Tate, Tuckasegee, and Tusquitee soils. All except
Braddock and Clifton soils have less than 35 percent clay in the control section. Braddock soils are on high
terraces. Clifton, Evard, and Fannin soils are on ridges and side slopes. Brevard, Cullasaja, Saunook, Tate,
Tuckasegee, and Tusquitee soils are on colluvial fans and toe slopes.
DRAINAGE AND PERMEABILITY: Well drained; moderate permeability in the subsoil and moderately
rapid permeability in the underlying material; medium internal drainage. Runoff class low on gentle slopes,
medium on strong and moderately steep slopes, and high on steeper slopes. Runoff is much lower where forest
litter has little or no disturbance.
USE AND VEGETATION: About one-half of the acres of this soil is in cultivation. Common trees in wooded
areas are yellow- poplar, eastern white pine, northern red oak, pitch pine, shortleaf pine and Virginia pine. The
understory includes flowering dogwood, rhododendron, mountain laurel and sourwood. Cleared areas are used
for cultivated crops such as corn, small grain, pasture, hayland, burley tobacco, vegetable crops and Christmas
trees.
DISTRIBUTION AND EXTENT: Mountain areas of North Carolina, Virginia, South Carolina, Georgia, and
Tennessee. The series is of large extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Morgantown, West Virginia
SERIES ESTABLISHED: Clay County, North Carolina; 1935.
REMARKS: The classification of the Hayesville series was changed in April 1989 to clayey, kaolinitic, mesic
Typic Kanhapludults. This is change is based on lab data from South Carolina, North Carolina, and Virginia that
indicates presence of a kandic horizon. The May 1995 revision added thickly -bedded metagraywacke and
metasandstone as allowable parent materials for Hayesville soils. Laboratory data from North Carolina State
University provided support for Hayesville soils being formed from these materials in Cherokee County, NC.
The 12/97 revision changes the particle size class from clayey to fine per the 7th Edition of Keys to Soil
Taxonomy (1996).
Diagnostic horizons and features recognized in this pedon are:
Ochric epipedon: The zone from 0 to 5 inches (Al and A2 horizons).
Kandic horizon: The zone from 5 to 48 inches (BA, Bt, and BC horizons).
Argillic horizon: The zone from 5 to 48 inches (BA, Bt, and BC horizons).
