Re: Supplemental Geotechnical Engineering Report —
Seasonal High Water Table
Proposed Family Dollar— 1213 E. Prospect Avenue

Terracon Report No. 71125072
Dear Mr. Tuitt:
MAR C 8 2013
=`0' C
Terracon Consultants, Inc. (Terracon) is pleased to provide this supplemental letter report for the
above referenced project and is subject to the limitations outlined in our original Geotechnical
Engineering Report, dated December 6, 2012. The purpose of this letter is to provide a
discussion on the seasonal high water table (SHWT) level at the subject site.
On January 14, 2013, Terracon performed two hand auger borings for the purpose of determining
the SHWT at the proposed Family Dollar at 1213 E. Prospect Avenue in Raeford, NC (Exhibit A-
1). One hand auger boring was performed in each of the two sand filter locations shown on the
plan prepared by Burton Engineering entitled "E. Prospect — FDS, Grading and Drainage Plan,
dated December 21, 2012". The plan was used as our base map included as Exhibit A-2.
The hand augers were observed while drilling and after completion for the presence and level of
groundwater. Groundwater was observed in the borings that were terminated at a depth of 4.5 to
5 feet. The borings were left open so that stabilized groundwater levels could be measured.
The soil samples obtained during our field exploration were also observed for redoximorphic
features of the soil profile to estimate the SHWT levels. Redoximorphic features (a gray or bluish -
gray colored soil matrix) and mottles are formed by the process of reduction, translocation and/or
oxidation of iron and manganese oxides as the water table fluctuates. A soil layer exhibiting
redoximorphic features can be representative of the seasonal high water table level. Logs of our
hand auger borings are included.

EXECUTIVE SUMMARY
A geotechnical investigation has been performed for the proposed Family Dollar to be located at
the intersection of Fayetteville Road and N. Parker Church Road in Raeford, North Carolina. Ten
(10) borings, designated B-01 through B-10, were performed to depths of approximately 10 to 15
feet below the existing ground surface in the proposed building and parking areas.
Based on the information obtained from our subsurface exploration, the site can be developed for
the proposed project. The following geotechnical considerations were identified:
© Based on the results of our subsurface exploration, it is our opinion that the soils at the
site are suitable for support of shallow foundations outlined in this report and structures
may be supported on conventional spread and strip footings with a net allowable bearing
pressure of 3,000 psf.
® The natural soils encountered at the boring locations may be excavated with
conventional construction equipment, such as bulldozers, backhoes, and trackhoes.
® The 2012 North Carolina State Building Code (NCSBC) seismic site classification for this
site is D. A geophysical exploration to develop the shear wave velocity profile to a depth
of 100 feet could be utilized to verify the seismic site class or as an attempt to justify a
higher seismic site class.
This summary should be used in conjunction with the entire report for design purposes. It
should be recognized that details were not included or fully developed in this section, and the
report must be read in its entirety for a comprehensive understanding of the items contained
herein. The section titled GENERAL COMMENTS should be read for an understanding of the

3.0 SUBSURFACE CONDITIONS
3.1 Geology
The project site is located in the Coastal Plain physiographic province of North Carolina. The
Coastal Plain consists mainly of marine sediments that were deposited during successive periods
of fluctuating sea level and moving shoreline. The soils in this province consist of sands, silts,
and clays with irregular deposits of shells, which are typical of those lain down in a shallow
sloping sea bottom. Recent alluvial sands, silts, and clays are typically present near rivers and
creeks. According to the 1985 Geologic Map of North Carolina, the site is located within the
Middendorf formation. This formation is described as consisting of sand, sandstone and
mudstone with clay balls and iron cemented concretions.
3.2 Typical Profile
Based on the results of the borings, subsurface conditions on the project site can be generalized
as follows:
The borings were generally advanced through approximately 4 to 6 inches of topsoil. Natural
materials were encountered below the surface materials to depths of approximately 10 to 15
Responsive ■ Resourceful ■ Reliable 2

Geotechnical Engineering Report 1%rraeon
Proposed Family Dollar — Raeford ■ Raeford, North Carolina

feet below existing grades. Natural materials encountered consist of silty sand, sandy silt,
sandy clay and poorly graded sand and visually classify as SM, ML, CL and SP, respectively,
in accordance with the Unified Soil Classification System (USCS). Standard penetration test
values (N-values) in the sands range from 2 to 58 blows per foot (bpf), indicating very loose to
very dense relative density. N-values range from 4 to 28 bpf in the silts and clays indicating a
medium stiff to very stiff consistency.
Conditions encountered at each boring location are indicated on the individual boring logs.
Stratification boundaries on the boring logs represent the approximate location of changes in soil
types; in -situ, the transition between materials may be gradual. Details for each of the borings
can be found on the boring logs in Appendix A of this report.
3.3 Groundwater
The boreholes were observed while drilling and after completion for the presence and level of
groundwater. Groundwater was not observed in any of the borings after the short amount of time
(less than one hour) the borings were left open. The borings were backfilled with the cuttings
immediately after completion, making subsequent groundwater measurements unobtainable.
The soil samples obtained during our field exploration were also observed for redoximorphic
features of the soil profile to estimate the seasonal high water table levels. Redoximorphic
features (a gray or bluish -gray colored soil matrix) and mottles are formed by the process of
reduction, translocation and/or oxidation of iron and manganese oxides as the water table
fluctuates. A soil layer exhibiting redoximorphic features can be representative of the seasonal
high water table level. Based on our observations of the soil samples, redoximorphic features
were not observed within the depth of our borings. Additionally, the relative moisture content of
the soil samples did not indicate the presence of groundwater within the depth of our borings.
Based on our experience in this area and the information obtained from field exploration, it is
our opinion that the seasonal high water table level occurs at a depth greater than 15 feet. ,
4.0 RECOMMENDATIONS FOR DESIGN AND CONSTRUCTION
4.1 Geotechnical Considerations
Based on the results of our subsurface exploration, it is our opinion that the proposed building
may be supported on conventional spread and strip footings with a net allowable bearing
pressure of 3,000 psf. Further details and recommendations are provided herein.

4.2 Earthwork
Existing tree cover, vegetation, topsoil, and any otherwise unsuitable material should be
removed from the construction areas prior to placing fill. The exposed subgrade soils in areas
to receive fill or at the subgrade elevation in cut areas should be proofrolled to detect soft or
loose soils and other unsuitable materials that may be present. Proofrolling should be
performed with a fully -loaded, tandem -axle dump truck or similar pneumatic -tired construction
equipment in the proposed pavement areas and a moderately loaded, tandem axle dump
truck or similar pneumatic -tired construction equipment weighing approximately 20 tons in the
proposed building area. A Terracon representative should observe this operation to aid in
delineating unstable soil areas. Proofrolling should be performed after a suitable period of dry
weather to avoid degrading an otherwise acceptable subgrade. Soils which continue to rut or
deflect excessively under the proofrolling operations should be remediated as recommended
by the geotechnical engineer.
Based on the borings and moisture condition of the samples, we do not anticipate that mass
undercutting of near -surface natural soils will be required; however, undercutting of any
soft/loose soils should be performed if soft/loose soils are encountered are at subgrade
elevations.
4.2.1 Compaction Requirements
We recommend that engineered fill be tested for moisture content and compaction during
placement. Should the results of the in -place density tests indicate the specified moisture or
compaction limits have not been met, the area represented by the test should be reworked
and retested as required until the specified moisture and compaction requirements are
achieved.
Engineered fill should meet the following compaction requirements:
I ITEM I DESCRIPTION I
8 to 10 inches or less in loose thickness when
heavy, self-propelled compaction equipment is
used
Fill Lift Thickness
4 to 6 inches in loose thickness when hand -
guided equipment (e.g. jumping jack or plate
compactor) is used
Minimum 95% of the material's maximum
standard Proctor dry density (ASTM D 698)
Compaction Requirements The upper 12 inches in pavement and building
areas should be compacted to at least 100% of
the materials maximum standard Proctor dry
density (ASTM D 698)

All locations and elevations.
1. Controlled, compacted fill should consist of approved materials that are free of organic matter and
debris. Frozen material should not be used, and fill should not be placed on a frozen subgrade. A
sample of each material type should be submitted to the geotechnical engineer for evaluation.
4.2.3 Grading and Drainage
Final surrounding grades should be sloped away from the buildings on all sides to minimize
ponding of water. Gutters and downspouts should drain water at least 10 feet beyond the
footprint of the proposed building. This can be accomplished through the use of splash -
blocks, downspout extensions, and flexible pipes that are designed to attach to the end of the
downspout. Flexible pipe should only be used if it is daylighted in such a manner that it
gravity -drains collected water. Splash -blocks should also be considered below hose bibs and
water spigots.
4.2.4 Earthwork Construction Considerations
The geotechnical engineer should be retained during the construction phase of the project to
observe earthwork and to perform necessary tests and observations during subgrade
preparation; to monitor proof rolling, placement and compaction of controlled compacted fills,
backfilling of excavations to the completed subgrade; and to observe footing excavations prior
to placing reinforcing steel.
4.2.5 Excavations
The soils encountered at the boring locations may be excavated with conventional
construction equipment, such as bulldozers, backhoes, and trackhoes.
As a minimum, all temporary excavations should be sloped or braced as required by
Occupational Safety and Health Administration (OSHA) regulations to provide stability and
safe working conditions. Temporary excavations will probably be required during grading
operations. The grading contractor should be responsible for designing and constructing

stable, temporary excavations and should shore, slope or bench the sides of the excavations
as required, to maintain stability of both the excavation sides and bottom. All excavations
should comply with applicable local, state and federal safety regulations, including the current
OSHA Excavation and Trench Safety Standards.
Construction site safety is the sole responsibility of the contractor who controls the means,
methods and sequencing of construction operations. Under no circumstances shall the
information provided herein be interpreted to mean that Terracon is assuming any responsibility
for construction site safety or the contractor's activities; such responsibility shall neither be
implied nor inferred.
4.3 Foundations
In our opinion, the proposed structure can be supported by shallow, spread footing foundation
systems bearing within the natural soils or new, engineered fill. Design recommendations for
shallow foundations for the proposed structures are presented in the following sections.

1. The recommended net allowable bearing pressure is the pressure in excess of the minimum
surrounding overburden pressure at the footing base elevation. Assumes soft/loose soils
identified during foundation evaluations are removed and replaced as recommended by the
geotechnical engineer.
4.3.2 Foundation Construction Considerations
The base of all foundation excavations should be free of water and loose soil and rock prior to
placing concrete. Concrete should be placed soon after excavating to reduce bearing soil
disturbance. Should the soils at bearing level become disturbed, saturated, or frozen, the
affected soil should be removed prior to placing concrete. Exposure to inclement weather can
introduce unwanted moisture into the footing subgrade. If construction occurs during
inclement weather, and concreting of foundations is not possible at the time they are
excavated, a layer of lean concrete should be placed on exposed bearing surfaces for
protection. Where high moisture conditions are encountered at footing bearing elevations, the
bottom of the excavations could be stabilized with a relatively clean, well -graded crushed
stone or gravel, or a lean concrete mud mat to provide a working base for construction.

The foundation bearing materials should be evaluated at the time of the foundation
excavation. A representative of the geotechnical engineer should use a combination of hand
auger borings and dynamic cone penetrometer (DCP) testing in conjunction with visual
observations to determine the suitability of the bearing materials for the design bearing
pressure. If encountered, excessively soft, loose or wet bearing soils should be remediated as
recommended by the geotechnical engineer.
4.4 Seismic Considerations
I Code Used I Site Classification I
2012 North Carolina State Building Code (NCSBC) I D'
1. The 2012 NCSBC requires a site soil profile determination extending a depth of 100 feet for seismic
site classification. The scope of work authorized did not include a boring to a depth of 100 feet.
The borings performed for this report extended to a maximum depth of 15 feet. A geophysical
exploration to develop the shear wave velocity profile to a depth of 100 feet could be utilized to verify
the seismic site class or as an attempt to justify a higher seismic site class.
The subsurface materials are not considered subject to liquefaction under the magnitude of
seismic events predicted for the area.

Aggregate base course/capillary break
4 inches of free draining granular material (< 5
percent passing the No. 200 sieve)
1. Floor slabs should be structurally independent of any building footings or walls to reduce the
possibility of floor slab cracking caused by differential movements between the slab and foundation.
Where appropriate, saw -cut control joints should be placed in the slab to help control the
location and extent of cracking. For additional recommendations refer to the ACI Design
Manual. Joints or any cracks that develop should be sealed with a water -proof, non -extruding
compressible compound specifically recommended for heavy duty concrete pavement and wet
environments.

The use of a vapor retarder should be considered beneath concrete slabs on grade that will be
covered with wood, tile, carpet or other moisture sensitive or impervious coverings, or when
the slab will support equipment sensitive to moisture. When conditions warrant the use of a
vapor retarder, the slab designer should refer to ACI 302 and/or ACI 360 for procedures and
cautions regarding the use and placement of a vapor retarder.
4.5.2 Floor Slab Construction Considerations
Upon completion of grading operations in the building areas, care should be taken to maintain
the recommended subgrade moisture content and density prior to construction of the building
floor slabs.
On most project sites, the site grading is generally accomplished early in the construction phase.
However as construction proceeds, the subgrade may be disturbed due to utility excavations,
construction traffic, desiccation, rainfall, etc. As a result, the floor slab subgrade may not be
suitable for placement of base rock and concrete and corrective action will be required.
We recommend the area underlying the floor slab be rough graded and then thoroughly
proofrolled with a loaded tandem axle dump truck prior to final grading and placement of base
rock. Particular attention should be paid to high traffic areas that were rutted and disturbed
earlier and to areas where backflled trenches are located. Areas where unsuitable conditions
are located should be repaired by removing and replacing the affected material with properly
compacted fill. All floor slab subgrade areas should be moisture conditioned and properly
compacted to the recommendations in this report immediately prior to placement of the base
rock and concrete.
4.6 Infiltration Testing
We understand that a detention pond and septic field are proposed at this project site.
Infiltration testing was performed at one SPT boring location (B-01) as shown on the Boring
Location Plan (Figure A-2). The boring was cleaned out with hand auger equipment after
drilling, and was filled with water to a depth of 24 inches and allowed to pre-soak for 24 hours.
After 24 hours, an additional 24 inches of water was added to the boring and the drop in the
water level was monitored for 1 hour. This process was repeated three times. Upon
completion of the infiltration testing, the boring was backfilled with the drilling cuttings. The
table below provides a summary of the infiltration rate measured from the final (fourth) test.

4.7 Pavements
4.7.1 Pavement Design Recommendations
lrerracon
Following the stripping of deleterious materials, we recommend the proposed pavement
subgrade be prepared and compacted in accordance with the recommendations provided in the
Earthwork section of this report. Proofrolling and recompacting of the upper 1-foot of subgrade is
recommended immediately prior to stone base placement. Soft or unstable areas delineated by
the proofrolling operations should be undercut or stabilized in -place to achieve the appropriate
subgrade support. Potential areas for encountering unsuitable or unstable soils are in the vicinity
of drainage features and in the low lying areas of the site.
Based on our borings and assumed grading, we anticipate the on -site sandy silt will be present at
subgrade elevation. Two pavement section alternatives are provided, one for light duty and one
for heavy duty. Loading conditions were provided as listed below:
Heavy duty: 30,576 ESAL's over 20-year design life
Light duty of 11,279 ESAL's over a 20 year design life
Recommended alternatives for flexible pavements, summarized for each traffic area, are as
follows:

INC DOT (inches)

(Light Duty) (Heavy Duty) i
Portland Cement Concrete 4,000 psi 6* 6
'Recommended thickness is based on the "Standard Pavement Design" outlined in the "Exhibit H
Family Dollar Geotechnical Report Requirements" document provided.
For areas subject to concentrated and repetitive loading conditions such as dumpster pads, truck
delivery docks and ingress/egress aprons, we recommend using a Portland cement concrete
pavement with a thickness of at least 7 inches underlain by at least 4 inches of crushed stone.
Prior to placement of the crushed stone the areas should be thoroughly proofrolled. For dumpster
pads, the concrete pavement area should be large enough to support the container and tipping
axle of the refuse truck.
ACI 330R-01 provides recommendations for control joints, joint spacing, and joint construction.
Concrete slabs should be separated from other structures or fixed objects within or abutting
paved areas with expansion joints to offset the effects of expected differential horizontal and
vertical movements.
The minimum pavement sections outlined above were recommended based on estimated soil
parameters and post -construction traffic loading conditions for this type of development. These
pavement sections do not account for heavy construction traffic during construction. A partially
constructed structural section may be subjected to heavy construction traffic that can result in
pavement deterioration and premature failure. Our experience indicates that this pavement
construction practice can result in pavements that will not perform as intended. Considering this
information, several alternatives are available to mitigate the impact of heavy construction traffic
on the pavement construction. These include using thicker sections to account for the
construction traffic, using some method of soil stabilization to improve the support characteristics
of the pavement subgrade, or by routing heavy construction traffic around paved areas.
4.7.2 Pavement Construction Considerations
Materials and construction of pavements for the project should be in accordance with the
requirements and specifications of the North Carolina Department of Transportation "Standard
Specifications for Roads and Structures'.

Geotechnical Engineering Report lr�rracon
Proposed Family Dollar — Raeford ■ Raeford, North Carolina
December 21, 2012 ■ Terracon Project No. 71125073
Site grading is generally accomplished early in the construction phase. However as construction
proceeds, the subgrade may be disturbed due to utility excavations, construction traffic,
desiccation, or rainfall. As a result, the pavement subgrade may not be suitable for pavement
construction and corrective action will be required. The subgrade should be carefully evaluated at
the time of pavement construction for signs of disturbance or excessive rutting. If disturbance
has occurred, pavement subgrade areas should be reworked, moisture conditioned, and properly
compacted to the recommendations in this report immediately prior to paving.
Base course or pavement materials should not be placed when the surface is wet. Surface
drainage should be provided away from the edge of paved areas to minimize lateral moisture
transmission into the subgrade.
Preventative maintenance should be planned and provided for through an on -going pavement
management program in order to enhance future pavement performance. Preventative
maintenance activities are intended to slow the rate of pavement deterioration, and to
preserve the pavement investment.
Preventative maintenance consists of both localized maintenance (e.g. crack sealing and
patching) and global maintenance (e.g. surface sealing). Preventative maintenance is usually
the first priority when implementing a planned pavement maintenance program and provides
the highest return on investment for pavements.
5.0 GENERAL COMMENTS
Terracon should be retained to review the final design plans and specifications so comments
can be made regarding interpretation and implementation of our geotechnical recommendations
in the design and specifications. Terracon also should be retained to provide observation and
testing services during grading, excavation, foundation construction and other earth -related
construction phases of the project.
The analysis and recommendations presented in this report are based upon the data obtained
from the borings performed at the indicated locations and from other information discussed in
this report. This report does not reflect variations that may occur between borings, across the
site, or due to the modifying effects of construction or weather. The nature and extent of such
variations may not become evident until during or after construction. If variations appear, we
should be immediately notified so that further evaluation and supplemental recommendations
can be provided.
The scope of services for this project does not include either specifically or by implication any
environmental or biological (e.g., mold, fungi, bacteria) assessment of the site or identification or
prevention of pollutants, hazardous materials or conditions. If the owner is concerned about the
potential for such contamination or pollution, other studies should be undertaken.

Field Exploration Description
The boring locations were laid out on the site by Terracon personnel utilizing a site plan provided
and were measured from available site features. Right angles for the boring locations were
estimated. The locations of the borings should be considered accurate only to the degree
implied by the means and methods used to define them.
The borings were drilled with an ATV -mounted rotary drill rig using hollow stem augers to
advance the boreholes. Samples of the soil encountered in the borings were obtained using the
split -barrel sampling procedure.
In the split barrel sampling procedure, the number of blows required to advance a standard 2
inch O.D. split barrel sampler the last 12 inches of the typical total 18 inch penetration by
means of a 140 pound hammer with a free fall of 30 inches, is the standard penetration
resistance value (SPT-N). This value is used to estimate the in -situ relative density of
cohesionless soils and consistency of cohesive soils.
An automatic SPT hammer was used to advance the split -barrel sampler in the borings
performed on this site. A significantly greater efficiency is achieved with the automatic
hammer compared to the conventional safety hammer operated with a cathead and rope. This
higher efficiency has an appreciable effect on the SPT-N value.
The samples were tagged for identification, sealed to reduce moisture loss, and taken to our
laboratory for further examination, testing, and classification. Information provided on the boring
logs attached to this report includes soil descriptions, consistency evaluations, boring depths,
sampling intervals, and groundwater conditions. The borings were backfilled with auger cuttings
prior to the drill crew leaving the site.
A field log of each boring was prepared by the drill crew. These logs included visual
classifications of the materials encountered during drilling as well as the driller's interpretation of
the subsurface conditions between samples. Final boring logs included with this report represent
the engineer's interpretation of the field logs and include modifications based on laboratory
observation and tests of the samples.

Proposed Family Dollar — Raeford o Raeford, North Carolina
December 21, 2012 o Terracon Project No. 71125073
Laboratory Testing
As part of the testing program, all samples were examined in the laboratory by experienced
personnel and classified in accordance with the attached General Notes and the Unified Soil
Classification System based on the texture and plasticity of the soils. The group symbol for the
Unified Soil Classification System is shown in the appropriate column on the boring logs and a
brief description of the classification system is included with this report in Appendix C.
At that time, the field descriptions were confirmed or modified as necessary and an applicable
laboratory testing program was formulated to determine engineering properties of the
subsurface materials.
Laboratory tests were conducted on selected soil samples and the test results are presented
on the boring logs in Appendix A. The laboratory test results were used for the geotechnical
engineering analyses, and the development of foundation and earthwork recommendations.
Laboratory tests were performed in general accordance with the applicable ASTM, local or
other accepted standards.
Selected soil samples obtained from the site were tested for the following engineering
properties:
o In -situ Water Content o Atterberg Limits
n Sieve Analysis
Responsive o Resourceful o Reliable

Water levels indicated on the boring logs are the levels measured in the borings at the times indicated. Groundwater levels at other
times and other locations across the site could vary. In pervious soils, the indicated levels may reflect the location of groundwater.
In low permeability soils, the accurate determination of groundwater levels may not be possible with only short-term observations.
DESCRIPTIVE SOIL CLASSIFICATION: Soil classification is based on the Unified Classification System. Coarse Grained Soils
have more than 50% of their dry weight retained on a #200 sieve; their principal descriptors are: boulders, cobbles, gravel or sand.
Fine Grained Soils have less than 50% of their dry weight retained on a #200 sieve; they are principally described as clays if they are
plastic, and silts if they are slightly plastic or non -plastic. Major constituents may be added as modifiers and minor constituents may
be added according to the relative proportions based on grain size. In addition to gradation, coarse -grained soils are defined on the
basis of their in -place relative density and fine-grained soils on the basis of their consistency.
