BLE Project No. J18-12228-02
BLE NC License No. C-1538

Dear Mr. Wearren,
Bunnell-Lammons Engineering, Incorporated (BLE) is pleased to present this
geotechnical exploration report for the above-referenced project. This report was
performed in general accordance with Bunnell-Lammons Engineering (BLE) Proposal
Number P18-0585 dated June 7, 2018. The purpose of this exploration was to develop
information about the site and subsurface soil conditions that could be used in preliminary
planning for the proposed bio-retention ponds. Project information for this report was
obtained from a review of current and historical aerial photography along with concept
drawings showing the proposed bio-retention ponds. BLE was provided the concept
stormwater drawings for High Hampton’s back of house, Fieldstone Phase 1 and resort
core dated May 18, 2018 as well as a boring location plan indicating sixteen (16) borings
and an excel spreadsheet with boring elevations for the proposed bio-retention basins.
Additional project information was obtained from our site visit performed by BLE during
the course of the preliminary geotechnical exploration.

PROJECT INFORMATION
High Hampton is currently planning an expansion to their resort in Cashiers, North
Carolina. Part of the expansion is to include the construction of 16 new bio-retention
ponds. These new ponds are associated with three expansion areas that include the
resort core, an area of new residential construction identified as Fieldstone Phase I, and
a back-of-house area associated with a new treatment plant and maintenance building.

We understand that seasonal high groundwater table elevations for the bio-retention
ponds and soil infiltration rates for permeable pavements is needed.

FIELD EXPLORATION
The bio-retention sites were explored by performing thirteen (13) soil test borings at the
approximate locations shown on the attached Boring Location Plan (reference Figure 1).
Borings RC-1 through RC-9 were performed at the resort core area, Borings F-1, F-2, F-
4 and F-5 were performed at the Fieldstone Phase 1 area. This corresponded to one
boring per pond, with the exception of Borings F-3, GM-1 and GM-2, which were not
accessible to our drill rig at the time of exploration. The soil test borings were performed
using a truck-mounted drill rig turning 2-1/4 inch I.D. hollow-stem augers. Ten of the 13
soil test borings were extended to their proposed depths below the existing ground
surface. Three of the 13 borings encountered shallow refusal. Soil samples were obtained
in accordance with ASTM D 1586 by driving a 1-3/8 inch I.D. split-spoon sampler with a
140-pound safety hammer. The boring locations were established in the field by BLE
personnel using the provided concept site plan layout and a hand-held GPS unit with 3 to
5 meter accuracy. Locations reported herein should be considered approximate. The Soil
Test Boring Records and a description of our field procedures are attached.

AREA GEOLOGY
The project site is located in the Blue Ridge Physiographic Province, an area underlain
by ancient igneous and metamorphic rocks. The virgin soils encountered in this area are
the residual product of in-place chemical weathering of the rock. In areas not altered by
erosion, previous construction or other activities of man, the typical residual soil profile
consists of clayey and silty soils near the surface where soil weathering is more advanced.
The near surface silty soils are typically underlain by sandy silts and silty sands.

The boundary between soil and rock is not sharply defined. This transitional zone is
termed partially weathered rock (PWR) and is normally found overlying the parent
bedrock. For engineering purposes, partially weathered rock is defined as residual
material with a standard penetration resistance in excess of 100 blows per foot, or 50
blows per 6 inches. Weathering is facilitated by fractures, joints, and the presence of less
resistant rock types. As a result, the profile of the partially weathered rock and hard rock
is quite irregular and erratic, even over short horizontal distances. Also, it is not unusual
to find lenses and boulders of hard rock and zones of partially weathered rock within the
soil mantle, well above the general bedrock level.

The upper soils along drainage features and in flood plain areas are generally water-
deposited (alluvial) materials that have been deposited by floods over geologic time or
eroded and washed down from adjacent higher ground. Alluvial soils are usually soft and
compressible, having never been consolidated by pressures in excess of their present
overburden.

SITE CONDITIONS
Site conditions were observed by Mr. King Williams during our site reconnaissance.

The resort and associated buildings are located on the southwest end of Hampton Lake.
Hampton Lake is fed by an unnamed creek that drains the area north of the lake. A review
of historic topographic maps indicates the area in and surrounding the lake was relatively
flat, and may have been an upland bog similar to those found in other nearby areas.
Significant development of the site has occurred over the years in association with the
resort. A number of buildings, driveways, parking areas and a golf course are now present.

BLE did not evaluate the existing buildings in great detail at the time of our site visit;
however, limited visual observations of the exterior of the structure indicate that the
buildings appear to be in good condition. No indications of excessive settlement were
apparent during our site visit, nor have we been notified of any settlement related problems
with the existing structure. There were no visible rock outcroppings and no apparent
groundwater springs were observed in the areas of the proposed resort at the time of our
site visit.

The Fieldstone Phase 1 area is currently a vacant, wooded site with a gravel road extending
from Cashiers School Road towards the south and to the west. The topography of is flat
to sloping.

The Back-of-House area is also a vacant, wooded site with a primitive 4-track trail. The
topography of the area was flat to sloping.

SUBSURFACE CONDITIONS
The descriptions below provide a general summary of the subsurface conditions
encountered. The Boring Logs included in the appendix contain detailed information
recorded at each boring location. The Boring Logs represent our interpretation of the field
logs based on engineering examination of the field samples. The lines designating the
interfaces between various strata represent approximate boundaries and the transition
between strata may be gradual. It should be noted that the soil conditions will vary
between boring locations.

Surface Materials
Borings RC-1 through RC-7, RC-9, F-1, F-2, F-4 and F-5 encountered topsoil and grass
thicknesses of 2 to 3 inches. Borings RC-8 and RC-9 encountered crushed stone
thicknesses of 2 to 8 inches.

Existing Fill
Soil interpreted as fill soil was encountered in borings RC-1, RC-3, RC-8 and F-1 to depths
ranging from 0 to 8 feet. No information regarding the past grading work has been
provided to BLE at the time of reporting. No compaction test data or field records of fill
placement were available for our review at the time this report was prepared. The fill
generally consisted of silty sands. SPT blow counts in the silty sands ranged from 6 to 9
bpf, indicating some compactive effort was applied during placement. It should be noted
that the content and quality of man-made fills can vary significantly.

Possible Fill or Residuum
A strata of soil that was difficult to discern from fill or residuum was encountered in boring
F-1 below the existing fill at depths ranging from 3 to 12 feet. Residuum is soil that has
weathered in place from the underlying parent bedrock. The possible fill or residuum
consisted of a silty sand. SPT resistance values in the possible fill or residuum was 3 to
6 bpf, indicating a very loose to loose consistency. It should be noted that the content
and quality of man-made fills can vary significantly.

Residuum
Residual soil, or residuum, was encountered in all 13 borings below the existing ground
surface at depths ranging from 0 to 20 feet. Residuum is soil that has weathered in
place from the underlying parent bedrock. The residuum generally consisted of silty
sands. SPT blow counts in the silty sand residuum ranged from 5 to 16 bpf, indicating a
loose to firm consistency. Borings RC-1 through RC-9 and F-1 were terminated in
residuum at depths of 10 to 20 feet below the ground surface.

Partially Weathered Rock
Partially weathered rock (PWR) was encountered in borings F-2, F-4 and F-5 to depths
ranging from 3 to 7 feet below the existing ground surface. Partially weathered rock
(PWR) is material that has weathered in place from the parent bedrock with an SPT
penetration resistance of greater than 50 blows per six inches. No samples were
recovered in the PWR.

Auger Refusal
Auger refusal was encountered in borings F-2, F-4 and F-5 at depths ranging from 4.5 to
7 feet (see Table 1). Refusal may result from boulders, lenses, ledges or layers of
relatively hard rock underlain by partially weathered rock or residual soil; refusal may also
represent the surface of relatively continuous bedrock. Core drilling procedures are
required to penetrate refusal materials and determine their character and continuity. Core
drilling was beyond the scope of this exploration.

Groundwater Conditions
Groundwater was not encountered at the time of drilling, however 11 piezometers were
installed and subsequent groundwater readings were taken. Refer to Table 1 below for
measured groundwater levels. It should be noted that groundwater levels may fluctuate
several feet with seasonal and rainfall variations and with changes in the water level in
nearby creeks and drainage features. Normally, the highest groundwater levels occur in
late winter and spring and the lowest levels occur in late summer and fall.

Due to recent rains and access issues, the drill rig was not able to access boring locations
GM-1, GM-2 and F-3. BLE conducted geotechnical explorations on April 9, 2018 at boring
location B-14. Due to the close proximity of the two borings (B-14 and GM-2), we have
included the data from B-14 in lieu of GM-2.

Sediment Basin Hydrogeology
A review of publicly available groundwater literature was performed to compliment the
soil boring exploration. A soil rating map was obtained from the United Stated Department
of Agriculture (USDA) NRCS website, which provided regional information regarding
water table elevations. The map designates soil deposits (designated as “map units”
across the site) and provides the depth to water for each deposit. The deposits located
within the proposed sediment basin are reported as the Edneyville-Chestnut land complex
for boring RC-9, symbolized as EdD, Nikwasi fine sandy loam land complex for borings
F-1 through F-5, symbolized as NkA, Sylva-Whiteside complex for borings GM-1 and GM-
2 (not drilled due to access) and Udorthents for borings RC-8, symbolized as Ud. Map
units the Edneyville-Chestnut land complex are shown as having a depth of greater than
78 inches over the time period from January through December (see Figure 2). Nikwasi
fine sandy loam land complex is shown as having a depth of 4 inches over the time period
from January through December. Sylva-Whiteside complex is shown as having a depth
of 30 inches over the time period from January through December.

Laboratory Test Results
Undisturbed soil samples of the residual soils were collected from Shelby tubes in borings
RC-4 and RC-7 at depths ranging from 12 to 14 feet below the ground surface. Grain
size distribution tests and permeability tests were conducted on these specimens The
permeability test indicated the residual soils exhibit permeabilities ranging from 1.5x10-4
to 6.0x10-5 cm/sec. Based on our experience in the region and the grain size distribution
tests, remolded soils (i.e. compacted fill soils) are anticipated to have similar permeability
characteristics.:

Assessment
A number of the bio-retention sites appear to have potential design and/or construction
issues as currently planned. Borings RC-1, RC-2, RC-5, RC-6 and F-1 encountered static
ground water levels above the planned basin bottom elevation. Borings F-2, F-4 and F-5
encountered auger refusal above the planned basin bottom elevation. High groundwater
has both design and regulatory impacts on bio-retention ponds and the potential for
shallow rock has construction feasibility implications. Modifications to plan elevations and
locations may be needed. The remaining locations appear to meet regulatory
requirements regarding the seasonal high groundwater table.
BASIS OF RECOMMENDATIONS
Our evaluation of foundation support conditions has been based on our understanding of
the project information and data obtained in our exploration as well as our experience on
similar projects. The general subsurface conditions utilized in our evaluation have been
based on interpolation of the subsurface data between the widely spaced limited borings.
Subsurface conditions between the borings may differ. If the project information is
incorrect or the structure location (horizontal or vertical) and/or dimensions are changed,
please contact us so that our recommendations can be reviewed. The discovery of any
site or subsurface conditions during construction which deviate from the data obtained in
this exploration should be reported to us for our evaluation. The assessment of site
environmental conditions for presence of pollutants in the soil, rock and groundwater of
the site was beyond the scope of this exploration.

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.

Description
"Water table" refers to a saturated zone in the soil. It occurs during specified
months. Estimates of the upper limit are based mainly on observations of the
water table at selected sites and on evidence of a saturated zone, namely
grayish colors (redoximorphic features) in the soil. A saturated zone that lasts for
less than a month is not considered a water table.
This attribute is actually recorded as three separate values in the database. A
low value and a high value indicate the range of this attribute for the soil
component. A "representative" value indicates the expected value of this attribute
for the component. For this soil property, only the representative value is used.

Field Exploration Procedures
Soil Test Borings
The borings were made by mechanically twisting a continuous flight steel auger into the soil. Soil
sampling and penetration testing were performed in general accordance with ASTM D 1586. At
assigned intervals, soil samples were obtained with a standard 1.4-inch I. D., 2-inch O. D., split-tube
sampler. The sampler was first seated 6 inches to penetrate any loose cuttings, and then driven an
additional 12 inches with blows of a 140-pound hammer falling 30 inches. The number of hammer
blows required to drive the sampler the final 12 inches was recorded and is designated the "standard
penetration resistance." The penetration resistance, when properly evaluated, is an index to the
strength of the soil and foundation supporting capability.
Representative portions of the soil samples, thus obtained, were placed in glass jars and transported
to the laboratory. In the laboratory, the samples were examined by a geotechnical engineer to verify
the field classifications of the driller. Test Boring Records are attached, showing the soil
descriptions and penetration resistance.
