HIES EASTOVER
EROSION, SEDIMENTATION & STORMWATER
Project Narrative
Our client wishes to construct a new hotel in Eastover. Project will include one building with required parking
and drives. Please see the attached plans. The total site is 6.55 acres and approximately 2.00 acres will be
disturbed during construction. This is the second phase to a project that started in 2018. The c-store and DQ
were completed in 2020. The majority of the site work, grading, and erosion control were completed for the
entire site. Phase 2 is for the construction of the hotel building. This will include minor site work, installation of
BMPs, and final paving etc.
Post construction stormwater will be handled through a series of storm piping and a stormwater wetland.
Soil erosion will be controlled with the use of perimeter silt fence, a skimmer basin, and a series of diversion
swales. Approximately 2.00 acres of area will be disturbed during construction. Several temporary diversions
will be utilized to direct flow into the skimmer basin. Silt fence inlet protection will be installed concurrently with
the installation of the new storm drain piping. Calculations for temporary skimmer basin sizing are found in the
following report. As stated before...the majority of the site work is complete and the site is currently stable.
Erosion control measures were designed in accordance with NCDENR Erosion and Sediment Control Planning
and Design Manual, 2006 edition.

Sequence Of Construction Activities
1. Determine and mark limits of disturbance.
2. Construct stabilized construction entrance.
3. Place perimeter sediment fence and stone outlets.
4. Construct temporary skimmer basins and temporary diversions. Place seeding
immediately after constructing these structures. These structures shall be
constructed prior to the disturbance of each contributing area.
5. Begin demolition of existing structures in accordance with the Demolition Plan.
6. Remove topsoil and stockpile for use on slopes and in berms. Stockpile area is
designated on plans or as directed by engineer.
7. Construct storm drainage. Excavated drop inlet protection and outlet protection to
be constructed concurrently with storm drains. Silt sacks are to be installed at
each inlet upon placement of base course.
8. Place temporary seeding on all disturbed areas.
9. Complete final grading.
10. Place permanent seeding and do final landscaping.
11. Remove temporary erosion control measures after site is stabilized.
12. Estimated time before final stabilization is 3 months after completion of
construction.
Maintenance Plan
1. All erosion and sediment control practices will be checked for stability and proper
operation following every runoff-producing rainfall, but at a minimum of once
every week. Any needed repairs will be made immediately to maintain all erosion
and sedimentation controls as designed.
2. Stabilization measures shall be initiated as soon as practicable in portions of the
site where construction activities have temporarily or permanently ceased,but in
no case more than 14 days after the construction activity in that portion of the site
has temporarily or permanently ceased,unless activity in that portion of the site
will resume within 21 days.
3. Silt/sediment fences will be repaired as necessary to maintain a barrier. Sediment
will be removed from behind the fence when it becomes about 0.5 feet deep.
Removed sediment shall be disposed of in a suitable area and stabilized to prevent
erosion and sedimentation.
4. All seeded areas will be fertilized,reseeded as necessary, and mulched to
maintain a vigorous, dense vegetative cover.
5. Additional control devices may be required during construction in order to control
erosion and/or off site sedimentation. All temporary control devices shall be
removed once construction is completed and the site is stabilized.
6. Where practicable, trenches should be filled, covered, and temporary seeding
applied at the end of each day.
7. Contractor must take necessary action to minimize the tracking of mud onto the
paved roadway from construction areas. The contractor shall daily remove
mud/soil from pavement, as maybe required.

Step 1. Determine the tailwater depth from channel characteristics below the
pipe outlet for the design capacity of the pipe_ If the tailwater depth is less
than half the outlet pipe diameter. it is classified mnnmuun tailwater condition.
If it is greater than half the pipe diameter. it is classified maximum condition.
Pipes that outlet onto wide fiat areas with no defined channel are assumed
to have a minimum tailwater condition unless reliable flood stage elevations
show otherwise.

Step 2. Based on the tailwater conditions determined in step 1. enter Figure
8.06a or Figure 8.06b_and determine d;,,riprap size and minimum apron length
(La). The d:. size is the median stone size in a well-graded nprap apron.
Step 3. Determine apron width at the pipe outlet. the apron shape. and the
apron width at the outlet end from the same figure used in Step 2.

Step 6. Fit the riprap apron to the site by making it level for the minimum
length, La. from Figure 8.06a or Figure 8.06b. Extend the apron farther
downstream and along channel banks until stability is assured. Keep the
apron as straight as possible and align it with the flow of the receiving stream.
Make any necessary alignment bends near the pipe outlet so that the entrance
into the receiving stream is straight.
Some locations may require lining of the entire channel cross section to assure
stability.
It may be necessary to increase the size of riprap where protection of the
channel side slopes is necessary (Appendix S.05)_ Where overfills exist at
pipe outlets or flows are excessive, a plunge pool should be considered, see
page 8.06.8.

Reference: Report of Seasonal High Water Table Estimation and Infiltration Testing
Holiday Inn Wade Additional
Wade, Cumberland County, North Carolina
ECS Project No. 49.21021
Dear Mr. Modi:
ECS Southeast, LLP (ECS) recently conducted a seasonal high water table (SHWT) estimation
and infiltration testing within the stormwater control measure (SCM) area(s) along Pembroke
Road in Wade, Cumberland County, North Carolina. This letter, with attachments, is the report
of our testing.
Field Testing
On August 16, 2023, ECS conducted an exploration of the subsurface soil conditions, in
accordance with the NCDEQ Stormwater Design Manual section A-2, at two additionally
requested locations shown on the attached Boring Location Plan (Figure 1). ECS used GPS
equipment in order to determine the boring locations. The purpose of this exploration was to
obtain subsurface information of the in situ soils for the SCM area(s). ECS explored the
subsurface soil conditions by advancing one hand auger boring into the existing ground surface
at each of the requested boring locations. ECS visually classified the subsurface soils and
obtained representative samples of each soil type encountered. ECS also recorded the SHWT
elevation observed at the time of the hand auger borings. The attached Infiltration Testing Form
provides a summary of the subsurface conditions encountered at the hand auger boring locations.
The SHWT elevation was estimated at the boring locations below the existing grade elevation. A
summary of the findings are as follows:
Location SHWT
1-5 35 inches
1-6 22 inches
ECS has conducted two additional infiltration tests utilizing a compact constant head
permeameter near the hand auger borings in order to estimate the infiltration rate for the
subsurface soils. Infiltration tests are typically conducted at two feet above the SHWT or in the
most restrictive soil horizon. Tests in clayey conditions are conducted for durations of up to 30
minutes. If a more precise hydraulic conductivity value is desired for these locations, then ECS
recommends collecting samples and performing laboratory permeability testing.

1-5 Tan/orange/gray sandy CLAY 30 inches <0.001
1-6 Orange/gray sandy CLAY 18 inches <0.001
Infiltration rates and SHWT may vary within the proposed site due to changes in elevation, soil
classification and subsurface conditions. ECS recommends that a licensed surveyor provide the
elevations of the boring locations.
Closure
ECS's analysis of the site has been based on our understanding of the site, the project information
provided to us, and the data obtained during our exploration. If the project information provided
to us is changed, please contact us so that our recommendations can be reviewed and
appropriate revisions provided, if necessary. The discovery of any site or subsurface conditions
during construction which deviate from the data outlined in this exploration should be reported to
us for our review, analysis and revision of our recommendations, if necessary. The assessment
of site environmental conditions for the presence of pollutants in the soil and groundwater of the
site is beyond the scope of this geotechnical exploration.
ECS appreciates the opportunity to provide our services to you on this project. If you have any
questions concerning this report or this project, please contact us.
Respectfully,

1.0 EXECUTIVE SUMMARY
ECS Carolinas, LLP (ECS) has completed a subsurface exploration and geotechnical
engineering services for the proposed site located in Eastover, Cumberland County, North
Carolina. This summary should not be considered apart from the entire text of the report with
all the qualifications and conditions mentioned herein. Once the site plans are developed,
additional site-specific geotechnical exploration should be conducted.
The soil test borings encountered organic topsoil at the initial ground surface with thicknesses
of approximately 2 inches. Underlying the organic topsoil to approximately 10 feet, soils
consisting of stiff to very stiff, fat clay (CH), very soft to very stiff, sandy lean clay (CL), very
loose to dense, clayey and silty sand (SC, SM) were encountered in the borings. From 10 feet
to termination depths ranging from about 15 to 20 feet, borings B-1 through B-6 typically
encountered stiff, sandy lean clay (CL) and very loose to medium dense, clayey, silty, and clean
sand (SC, SM, SP).
The on-site sandy soils (SC, SM, SP) should be appropriate for use as backfill material for this
project, provided their moisture contents are within the acceptable range outlined in this report.
We anticipate that minor cuts and fills on the order of 3 feet or less will be incorporated into the
development of the site, with greater fill depths being anticipated for existing ditches at the site.
A perched groundwater condition may exist on the site and temporary groundwater control
measures may be necessary on the perimeter of the site.
Provided the site preparation recommendations in this report are followed, proposed lightly to
moderately loaded structures (column loads up to 150 kips and wall loads up to 5 kips per foot)
may be supported on conventional shallow foundations. For footings supported on firm natural
soil materials or new-engineered fill materials over firm natural soils, an allowable bearing
pressure of 2,000 pounds per square foot (psf) is recommended. In order to achieve adequate
bearing and reduce the potential for post construction settlements of the structures, the
loose/soft near-surface soils encountered in the vicinity of boring B-2 may require localized
undercutting and replacement or other appropriate remedial activities if they exist at the
foundation subgrade elevation in building areas. Aggregate pier systems and driven timber
piles are alternative options that can be used for the foundation of the building instead of
undercutting the soft soils. Further details describing the foundation options are provided in
section 5.3 "Foundations Recommendations" of this report.
Based on the boring data, site conditions are suitable for a typical slab-on-grade section.
Therefore, we recommend supporting the floor slab as a slab-on-grade over existing natural
soils and new compacted structural fill that are stable when proofrolled.
Based on the boring data, site conditions are suitable for support of asphaltic or Portland
cement concrete pavement sections according to the criteria outlined in this report.
Based on the boring data, difficult excavations are not anticipated for shallow foundation or
utility excavations.

2.0 PROJECT OVERVIEW
2.1 Project Information
The project consists of the construction of a multi-story hotel along with associated parking and
driveways. The site is located near the intersection of Pembroke Lane and Goldsboro Road in
Eastover, Cumberland County, North Carolina. No additional project information including
structural information was available at the time of this report.
2.2 Scope of Work
The site was explored by drilling eight soil test borings (Borings B-1 through B-8) and sampling
the soils to termination and refusal depths ranging from approximately 10 to 20 feet below
existing site grades. The boring locations were located in the field by ECS personnel using
handheld GPS equipment and existing site features as reference. The locations shown should
be considered approximate given the methods used. A Site Location Plan and Boring Location
Diagram are provided in Appendix A of this report.
2.3 Purposes of Exploration
The purpose of this exploration program was to determine the soil and groundwater conditions
at the site and to develop engineering recommendations to assist in the design and
construction of the proposed project. We accomplished these objectives as follows:
• Performing a site reconnaissance to evaluate the existing site conditions,
• Performing soil test borings to explore the subsurface soil and groundwater
conditions,
• Performing laboratory tests on selected representative soil samples from the borings
to evaluate pertinent engineering properties; and,
• Analyzing the field and laboratory data to develop appropriate geotechnical
engineering design and construction recommendations.

3.0 FIELD EXPLORATION
3.1 Exploration Procedures
The soil borings were performed with a drill rig, which utilized hollow stem augers (HSA) to
advance the boreholes.
Representative soil samples were obtained by means of the split-barrel sampling procedure in
general accordance with ASTM Specification D-1586. In this procedure, a 2-inch O. D. split-
barrel sampler is driven into the soil a distance of 18 inches by a 140 pound hammer with a free
fall of 30 inches. The number of blows required to drive the sampler through the final 12-inch
interval is termed the Standard Penetration Test (SPT) N-value and is indicated for each
sample on the boring logs.
The SPT N-value can be used to provide a qualitative indication of the in-place relative density
of cohesionless soils. In a less reliable way, SPT N-values provide an indication of consistency
for cohesive soils. These indications of relative density and consistency are qualitative, since
many factors can significantly affect the SPT N-value and prevent a direct correlation between
drill crews, drill rigs, drilling procedures, and hammer-rod-sampler assemblies.
Field logs of the soils encountered in the borings were maintained by the drill crew. The soil
samples obtained from the drilling operations were sealed in containers and were brought to
ECS' laboratory for visual classification.
3.2 Laboratory Testing Program
Representative soil samples obtained during our field exploration were selected and tested in
our laboratory to check field classifications and to determine pertinent engineering properties.
The laboratory testing program included:
• visual classifications of soil according to ASTM D 2487;
• index property testing included natural moisture content determinations (ASTM D 2216),
grain size analyses (ASTM D 1140), and Atterberg Limits (ASTM D 4318).
Data obtained from the laboratory tests are included on the Laboratory Testing Summary and in
Appendix C of this report.

4.0 SUBSURFACE EXPLORATION
4.1 Site Conditions
The site is located near the intersection of Pembroke Lane and Goldsboro Road in Eastover,
Cumberland County, North Carolina. The site is relatively level, cleared to moderately wooded,
and slopes upward from west to east with approximate site elevations ranging from 128 to 134
feet.
4.2 Site Geology
The site is located in the Coastal Plain Physiographic Province of North Carolina. The Coastal
Plain is composed of seven terraces, each representing a former level of the Atlantic Ocean.
Soils in this area generally consist of sedimentary materials transported from other areas by the
ocean or rivers. These deposits vary in thickness from a thin veneer along the western edge of
the region to more than 10,000 feet near the coast. The sedimentary deposits of the Coastal
Plain rest upon consolidated rocks similar to those underlying the Piedmont and Mountain
Physiographic Provinces. In general, shallow unconfined groundwater movement within the
overlying soils is largely controlled by topographic gradients. Recharge occurs primarily by
infiltration along higher elevations and typically discharges into streams or other surface water
bodies. The elevation of the shallow water table is transient and can vary greatly with seasonal
fluctuations in precipitation.
4.3 Soil Conditions
The soil conditions at each boring location are noted on the individual boring logs presented in
Appendix B. A general description is provided below and a summary of the soil stratigraphy is
shown on the Generalized Subsurface Profile in Appendix A. Subsurface conditions should be
expected to vary between boring locations.
The soil test borings encountered organic topsoil at the initial ground surface with thicknesses
of approximately 2 inches. The topsoil thicknesses reported on the logs was based on driller
observations and should be considered approximate. It should be noted that topsoil depths are
expected to vary throughout the site.
Underlying the organic topsoil to approximately 10 feet, soils consisting of stiff to very stiff, fat
clay (CH), very soft to very stiff, sandy lean clay (CL), very loose to dense, clayey and silty sand
(SC, SM) were encountered in the borings. The SPT resistance values (N-values) in the soils
ranged from weight of hammer (W.O.H) to 37 blows per foot (bpf).
From 10 feet to auger refusal depths ranging from about 15 to 20 feet, borings B-1 through B-6
typically encountered stiff, sandy lean clay (CL) and very loose to medium dense, clayey, silty,
and clean sand (SC, SM, SP) with N-values ranging from 3 to 11 bpf.

ECS Project Number 33:3711
4.4 Groundwater
Groundwater was encountered at approximate depths ranging from 1 to 8 feet below existing
grades at borings B-1, B-2, B-5, and B-6. At borings B-3, B-4, B-7, and B-8 groundwater was
not encountered, however, cave in depths were observed to range from 6.5 to 8 feet. Cave in
depths can sometimes be indicative of groundwater. Based on the groundwater measurements
and our experience in the area, the groundwater readings are indicative of a perched water
table.
The highest groundwater observations are normally encountered in the late winter and early
spring. Variations in the location of the long-term water table may occur as a result of changes
in precipitation, evaporation, surface water runoff, and other factors not immediately apparent at
the time of this exploration. Extended monitoring of the groundwater using wells would be
required to determine the fluctuation of the groundwater level over time.
4.5 Laboratory Test Results
The moisture contents in the tested samples ranged from 14.0 to 24.5 percent.
In the tested samples, the percent passing the No. 200 sieve ranged from 21.1 to 48.0 percent.
The Atterberg Limit tests resulted in liquid limits (LL) ranging from 40 to 56 and plastic limits
(PL) ranging from 20 to 25 in the tested samples, respectively.
Specific laboratory test results are provided in Appendix C of this report.

5.0 PRELIMINARY ANALYSIS AND RECOMMENDATIONS
The following preliminary design and construction recommendations are based on our above-
stated understanding of the proposed potential development and on the data obtained from the
field exploration, visual soil classification, and laboratory results. The following preliminary
recommendations are for preliminary design purposes. Once preliminary structural loading,
geometry, and location of the structure are developed, we request the opportunity to review our
recommendations in light of the new information and revise them as necessary.
5.1 Subgrade Preparation
The first step in preparing the site for the proposed construction should be to remove
vegetation, rootmat, topsoil, debris, deleterious materials and other soft or unsuitable materials
from the existing ground surface. These operations should extend at least 10 feet, where
possible, beyond the planned limits of the proposed structures and pavements.
The exposed subgrade soils in structural and pavement areas should be proofrolled using a
loaded dump truck, prior to placing any new fill to raise the grade. The subgrade soils in cut
areas should also be proofrolled. The loaded dump truck should have an axle weight of at least
10 tons. Proofrolling should be observed by an experienced geotechnical engineer, or their
personnel, at the time of construction to aid in identifying areas with soft or unsuitable materials.
Soft or unsuitable materials encountered during proofrolling should be removed and replaced
with an approved backfill compacted to the criteria given in Section 5.3 Fill Placement and Soil
Compaction. Undercutting should be anticipated due to the presence of soft clays/loose sands
in the upper three feet.
Site subgrade conditions will be significantly influenced by weather conditions.
Subgrades that are evaluated after periods of rainfall will not respond as well to proofrolling as
subgrades that are evaluated after periods of more favorable weather. We strongly
recommend that rubber tire equipment not be used if subgrade conditions exhibit elevated
moisture conditions. The contractor should use tracked equipment to minimize the degradation
of marginally stable subgrades.
The preparation of fill subgrades, as well as proposed building subgrades, should be observed
on a full-time basis by ECS personnel. These observations should be performed by a
geotechnical engineer, or his representative, to ensure that the unsuitable materials have been
removed and that the prepared subgrade is suitable for support of the proposed construction
and/or fills.
5.2 Groundwater Control
Temporary groundwater control measures may be necessary around the perimeter of the
building pad and pavement areas to address the perched groundwater condition.
Groundwater control is the purposeful drawdown of groundwater below subgrades, foundations,
slabs, or pavements to facilitate construction and to mitigate long term problems associated
with groundwater. It is the contractor's responsibility to plan for and budget for temporary
groundwater control. The means and methods of lowering the groundwater are at the
contractor's discretion. Temporary groundwater control measures typically consist of gravity
ditches, well points, sump pumps, pumping from gravel lined and cased sumps, or other
6
Report of Subsurface Exploration and Geotechnical Engineering Services June 22,2016
Holiday Inn&Suites
Eastover,Cumberland County, North Carolina
ECS Project Number 33:3711
suitable methods. Whatever method used, the groundwater control should be in place and
operating continuously (around the clock) to achieve and maintain the desired drawdown in
advance of excavation, proofrolling, compaction or other construction. Permanent groundwater
control measures typically consist of French drain systems and/or permanent sumps/pumps.
5.3 Engineered Fill Placement
Following the removal of deleterious surface and subsurface materials, and after achieving a
stable subgrade, engineered fills can be placed and compacted to achieve the desired site
grades. Fill for support of the proposed construction and for backfill of utility lines within
expanded building and pavement limits should consist of an approved material, free of organic
matter and debris and cobbles greater than 3 inches, and have a Liquid Limit (LL) and Plasticity
Index (PI) less than 40 and 20, respectively. We also recommend that fills within structural
areas have a modified Proctor (ASTM D 1557) maximum dry density of at least 100 pounds per
cubic foot (pcf).
Unsuitable fill materials include topsoil, organic materials (OH, OL), and high plasticity clays
and silts (CH, MH). Such materials removed during grading operations should be either
stockpiled for later use in landscape fills, or placed in approved on or off-site disposal areas.
Existing soils containing significant amounts of organic matter will not be suitable for re-use as
engineered fill. As such, the organic content of the near surface soils should be evaluated to
determine if some of these soils will be suitable for re-use as engineered fill. Natural fine-
grained soils classified as clays or silts (CL, ML) with LL and PI greater than 40 and 20,
respectively, should be evaluated by the geotechnical engineer at the time of construction to
determine their suitability for use as engineered fill.
Prior to the commencement of fill operations and/or utilization of any off-site borrow materials,
the contractor should provide representative samples of the proposed fill soils to the
geotechnical engineer. The geotechnical engineer can determine the material's suitability for
use as an engineered fill and develop moisture-density relationships in accordance with the
recommendations provided herein. Samples should be provided to the geotechnical engineer
at least 3 to 5 days prior to their use in the field to allow for the appropriate laboratory testing to
be performed.
Fill materials placed within the building and pavement areas should be placed in lifts not
exceeding 8 inches in loose lift thickness and moisture conditioned to within their working range
of optimum moisture content. The fills should then be compacted to a minimum of 95 percent
of the soil's modified Proctor (ASTM D 1577) maximum dry density. The typical working range
of optimum moisture for the natural Coastal Plain soils at the site is expected to be within
approximately 3 percent of the optimum moisture content. Care should also be taken to provide
a smooth, gently sloping ground surface at the end of each day's earthwork activities to help
reduce the potential for ponding and absorption of surface water.
Grade controls should also be maintained throughout the filling operations. Filling operations
should be observed on a full-time basis by a qualified representative of ECS to determine that
the required degrees of compaction are being achieved. We recommend that a minimum of
one compaction test per 2,500-square-foot area be performed for each lift of controlled fill.
Within trench or other localized excavations at least one test shall be performed for each 200
Report of Subsurface Exploration and Geotechnical Engineering Services June 22,2016
Holiday Inn&Suites
Eastover,Cumberland County, North Carolina
ECS Project Number 33:3711
linear feet of each lift of fill. The elevation and location of the tests should be clearly identified
at the time of fill placement. Areas which fail to achieve the required degree of compaction
should be re-worked until the specified degree of compaction is achieved. Failing test areas
may require moisture adjustments or other suitable remedial activities in order to achieve the
required compaction.
Fill materials should not be placed on frozen, frost-heaved, and/or soils which have been
recently subjected to precipitation. Wet or frozen soils should be removed prior to the
continuation of site grading and fill placement. Borrow fill materials, if required, should not
contain excessively wet or frozen materials at the time of placement. Additionally, if grading
operations occur during the winter months, frost-heaved soils should be removed prior to
placement of engineered fill, granular sub-base materials, foundation or slab concrete, and
asphalt pavement materials.
If problems are encountered during the site grading operations, or if the actual site conditions
differ from those encountered during our subsurface exploration, the geotechnical engineer
should be notified immediately.
5.4 Foundations
Shallow Foundations- Provided that the subgrade preparation and earthwork operations are
completed in strict accordance with the recommendations of this report, the proposed
residential structures can be supported on conventional shallow foundations bearing on
approved natural materials and/or properly compacted fill. We recommend a maximum net
allowable design soil bearing pressure of 2,000 psf for proportioning shallow foundations. To
reduce the possibility of foundation bearing failure and excessive settlement due to local shear
or "punching" failures, we recommend that continuous footings have a minimum width of 18
inches and that isolated column footings have a minimum lateral dimension of 30 inches.
Furthermore, footings should bear at a depth to provide adequate frost cover protection. For
this region, we recommend the bearing elevation be a minimum depth of 18 inches below the
finished exterior grade or in accordance with the local building code requirements.
Undercutting of up to 8 feet may be required in the vicinity of Boring B-2 due to the presence of
very loose/very soft soils. Once structural loads and site grades are finalized, ECS requests the
opportunity to review and revise our recommendations, if necessary.
The settlement of a structure is a function of the compressibility of the bearing materials,
bearing pressure, actual structural loads, fill depths, and the bearing elevation of footings with
respect to the final ground surface elevation. Estimates of settlement for foundations bearing
on engineered or non-engineered fills are strongly dependent on the quality of fill placed.
Factors which may affect the quality of fill include maximum loose lift thickness of the fills
placed and the amount of compactive effort placed on each lift. Provided that the
recommendations outlined in this report are strictly adhered to, we expect that total settlements
for the proposed construction are expected to be in the range of 1 inch or less, while the
differential settlement will be approximately '/2 of the anticipated total settlement. This analysis
is based on our engineering experience and assumed structural loadings for this type of
structure, and is intended to aid the structural engineer with his design.

The net allowable soil bearing pressure refers to that pressure which may be transmitted to the
foundation bearing soils in excess of the final minimum surrounding overburden pressure. The
final footing elevation should be evaluated by ECS personnel to verify that the bearing soils are
capable of supporting the recommended net allowable bearing pressure and suitable for
foundation construction. These evaluations should include visual observations, hand rod
probing, and dynamic cone penetrometer (ASTM STP 399) testing, or other methods deemed
appropriate by the geotechnical engineer at the time of construction.
If unsuitable materials are encountered at the base of a foundation excavation, it will be
necessary to lower the base of the footing through the unsuitable materials or to undercut the
unsuitable soils and to restore original bearing levels by placing compacted engineered fill
materials, compacted graded aggregate base, No. 57 stone, or concrete. These evaluations
should be performed within each column footing excavation and at intervals not greater than 50
feet in continuous footing excavations.
Exposure to the environment may weaken the soils at the foundation bearing level if the
foundation excavations remain exposed during periods of inclement weather. This is especially
true for the fine-grained soils at the site. Therefore, foundation concrete should be placed the
same day that proper excavation is achieved and the design bearing pressure is verified. If the
bearing soils are softened by surface water absorption or exposure to the environment, the
softened soils must be removed from the foundation excavation bottom immediately prior to
placement of concrete. If the foundation excavation must remain open overnight, or if rainfall is
imminent while the bearing soils are exposed, we recommend that a 2 to 3-inch thick "mud mat"
of "lean" concrete be placed over the exposed bearing soils before the placement of reinforcing
steel.
Aggregate Pier System: A ground improvement system, such as an aggregate pier system
combined with conventional shallow foundations can be utilized to support the proposed
structure. An aggregate pier system is a ground improvement method used to improve shallow
to intermediate, soft clay, loose silt, and loose sand soil for support of shallow foundations.
Aggregate piers improve soft soil and fill by vibration, compaction, and ramming of thin lifts of
crushed rock into a drilled hole. Soft soil is removed from the ground and then very dense, high
quality crushed rock is compacted into the drilled hole which expands the hole into the adjacent
soil. The cavity expansion effects increase the strength and stiffness of adjacent soil. The
compaction and ramming of thin lifts of crushed rock increases the strength and stiffness,
increases soil bearing capacity, and reduces soil compressibility. Aggregate piers can allow the
soil to support heavier loads on conventional shallow spread and strip footings with reduced
settlement.
If an aggregate pier system is selected for support of foundations, we recommend that the
following issues be considered prior to construction:
• Specifications for the aggregate pier system for support of foundations should be
prepared by a qualified specialty contractor.
• One demonstration pier should be installed with the aggregate pier installer's standard
procedures and then load-tested to determine the modulus. The load testing setup and
procedures should be selected by the aggregate pier installer and submitted for review
to the project geotechnical engineers. The demonstration pier should be installed at the
foundation grade level.

• The aggregate pier element installation operations should be conducted under the
continuous observation of the geotechnical engineer's representative. This observation
is conducted to reduce the potential for short aggregate pier element installations and
excessive aggregate lift thicknesses.
Driven Timber Piles: The structure can be supported on a deep foundation system consisting
of driven timber piles. The allowable capacities and embedment depths for an 8-inch square
timber pile are presented in the summary table below.

Depth (ft) (kips) (kips) (kips)

Pile capacity analyses were performed assuming a free head condition and the provided
compression and tension capacities are based on a factor of safety of 2.0 and 3.0, respectively.
We recommend that the pile driving hammer used to install each timber pile have a minimum
rated energy blow of 8,000 foot-pounds. Driving criteria and bearing elevations should be
established prior to driving piles.
It is suggested that several over length piles be driven prior to the start of production pile
driving, to establish the driving criteria, pile lengths to be ordered and to determine if auger
"pilot" holes are justified. Production piles should not be ordered until the pile lengths can be
determined. A minimum of two over length piles are recommended for the structure.
The over length piles could be driven in production pile locations. Pile installation operations
and load tests, if necessary, should be monitored by a senior soil technician working under the
supervision of a Licensed Engineer. ECS would be pleased to develop driving criteria for the
project, once the method of installation and the contractor has been selected.
5.5 Slabs-on-Grade
Slabs-on-grade can be adequately supported on undisturbed, low-plasticity soils or on newly-
placed engineered fill provided the site preparation and fill recommendations outlined herein are
implemented. For a properly prepared site, a modulus of subgrade reaction (ks) for the soil of
150 pounds per cubic inch for the soil can be used. This value is representative of a 1-ft square
loaded area and may need to be adjusted depending on the size and shape of the loaded area
depending on the method of structural analysis.
We recommend the slabs-on-grade be underlain by a minimum of 4 inches of granular material
having a maximum aggregate size of 1'/2 inches and no more than 2 percent fines. Prior to
placing the granular material, the floor subgrade soil should be properly compacted, proofrolled,
and free of standing water, mud, and frozen soil. A properly designed and constructed capillary
break layer can often eliminate the need for a moisture retarder and can assist in more uniform
curing of concrete. If a vapor retarder is considered to provide additional moisture protection,
special attention should be given to the surface curing of the slabs to minimize uneven drying of
10

ECS Project Number 33:3711
the slabs and associated cracking and/or slab curling. The use of a blotter or cushion layer
above the vapor retarder can also be considered for project specific reasons.
Please refer to ACI 302.1R96 Guide for Concrete Floor and Slab Construction and ASTM E
1643 Standard Practice for Installation of Water Vapor Retarders Used in Contact with Earth or
Granular Fill under Concrete Slabs for additional guidance on this issue.
In order to minimize the crack width of shrinkage cracks that may develop near the surface of
the slab, we recommend mesh reinforcement as a minimum be included in the design of the
floor slab. For maximum effectiveness, temperature and shrinkage reinforcements in slabs on
ground should be positioned in the upper third of the slab thickness. The Wire Reinforcement
Institute recommends the mesh reinforcement be placed within 2 inches below the slab surface
or within upper one-third of slab thickness, whichever is closer to the surface.
Adequate construction joints, contraction joints and isolation joints should also be provided in
the slab to reduce the impacts of cracking and shrinkage. Please refer to ACI 302.1R96 Guide
for Concrete Floor and Slab Construction for additional information regarding concrete slab joint
design.
5.6 Pavement Design Considerations
For the design and construction of exterior pavements, the subgrades should be prepared in
strict accordance with the recommendations in the "Subgrade Preparation" and "Engineered Fill
Placement" sections of this report. An important consideration with the design and construction
of pavements is surface and subsurface drainage. Where standing water develops, either on
the pavement surface or within the base course layer, softening of the subgrade and other
problems related to the deterioration of the pavement can be expected. Furthermore, good
drainage should minimize the possibility of the subgrade materials becoming saturated during
the normal service period of the pavement.
Actual traffic conditions were not provided to ECS. However, based on our experience for light
duty traffic for similar projects, a light duty flexible pavement section may consist of 2 inches of
surface SF9.5 mix overlying at least 6 inches of compacted ABC stone in the parking and drive
aisle areas. Similarly, a heavy duty flexible pavement section may consist of 3 inches of
surface SF9.5 mix overlying at least 8 inches of compacted graded aggregate base in the
roadway areas. For a rigid pavement section, we recommend 6 inches of 450 psi flexible
strength concrete overlying at least 6 inches of compacted ABC stone in the roadway areas.
Regardless of the section and type of construction utilized, saturation of the subgrade materials
and asphalt pavement areas results in a softening of the subgrade material and shortened life
span for the pavement. Therefore, we recommend that both the surface and subsurface
materials for the pavement be properly graded to enhance surface and subgrade drainage. By
quickly removing surface and subsurface water, softening of the subgrade can be reduced and
the performance of the parking area can be improved. Site preparation for the parking areas
should be similar to that for the building area including stripping, proofrolling, and the placement
of compacted structural fill.
Please note that large, front-loading trash dumpsters frequently impose concentrated front-
wheel loads on pavements during loading. This type of loading typically results in rutting of
Report of Subsurface Exploration and Geotechnical Engineering Services June 22,2016

Eastover,Cumberland County, North Carolina
ECS Project Number 33:3711
bituminous pavements and ultimately pavement failures and costly repairs. Consequently, we
recommend the use of an 8 inch thick, mesh reinforced concrete slab that extends the entire
length of the truck. Concrete pavements should be properly jointed and reinforced as needed to
help reduce the potential for cracking and to permit proper load transfer.
5.7 Site Drainage
Positive drainage should be provided around the perimeter of the pavement to minimize the
potential for moisture infiltration into the subgrade soils. We recommend that landscaped areas
adjacent to the pavements be sloped away from the construction and maintain a fall of at least
6 inches for the first 10 feet outward from the structure. The parking lots, sidewalks, and other
paved areas should also be sloped to divert surface water away from the proposed pavement.
The proper diversion of surface water during site grading and construction will help reduce the
potential for delays associated with periods of inclement weather. The proper diversion of
surface water is especially critical since portions of the site soils are expected to be moisture
sensitive. Based upon our past experience, the use of "crowning" large areas of exposed soils
should be useful to help divert surface water from the prepared subgrades.
5.8 Construction Considerations
It is imperative to maintain good site drainage during earthwork operations to help maintain the
integrity of the surface soils. The surface of the site should be kept properly graded to enhance
drainage of surface water away from the proposed construction areas during the earthwork
phase of this project. We recommend that surface drainage be diverted away from the
proposed pavements areas without significantly interrupting its flow. Other practices would
involve crowning and sealing the exposed soils daily with a smooth-drum roller at the end of the
day's work to reduce the potential for infiltration of surface water into the exposed soils.
The key to minimizing disturbance problems with the soils is to have proper control of the
earthwork operations. Specifically, it should be the earthwork contractor's responsibility to
maintain the site soils within a workable moisture content range to obtain the required in-place
density and maintain a stable subgrade. Scarifying and drying operations should be included in
the contractor's price and not be considered an extra to the contract. In addition, construction
equipment cannot be permitted to randomly travel across the site, especially once the desired
final grades have been established. Construction equipment should be limited to designated
lanes and areas, especially during wet periods to minimize disturbance of the site subgrades. It
will likely be necessary to utilize tracked equipment during grading operations particularly if the
subgrade soils exhibit elevated moisture conditions.

GENERAL CONDITIONS
The analysis, conclusions, and recommendations submitted in this report are based on the
exploration previously outlined and the data collected at the points shown on the attached
location plan. This report does not reflect specific variations that may occur between test
locations. The borings were located where site conditions permitted and where it is believed
representative conditions occur, but the full nature and extent of variations between borings and
of subsurface conditions not encountered by any boring may not become evident until the
course of construction. If variations become evident at any time before or during the course of
construction, it will be necessary to make a re-evaluation of the conclusions and
recommendations of this report and further exploration, observation, and/or testing may be
required.
This preliminary report has been prepared in accordance with generally accepted soil and
foundation engineering practices and makes no other warranties, either express or implied, as
to the professional advice under the terms of our agreement and included in this report. The
recommendations contained herein are made with the understanding that the contract
documents between the owner and foundation or earthwork contractor or between the owner
and the general contractor and the caisson, foundation, excavating and earthwork
subcontractors, if any, shall require that the contractor certify that all work in connection with
foundations, piles, caissons, compacted fills and other elements of the foundation or other
support components are in place at the locations, with proper dimensions and plumb, as shown
on the plans and specifications for the project.
Further, it is understood the contract documents will specify that the contractor will, upon
becoming aware of apparent or latent subsurface conditions differing from those disclosed by
the original soil exploration work, promptly notify the owner, both verbally to permit immediate
verification of the change, and in writing, as to the nature and extent of the differing conditions
and that no claim by the contractor for any conditions differing from those anticipated in the
plans and specifications and disclosed by the soil explorations will be allowed under the
contract unless the contractor has so notified the owner both verbally and in writing, as required
above, of such changed conditions. The owner will, in turn, promptly notify ECS of the
existence of such unanticipated conditions and will authorize such further exploration as may be
required to properly evaluate these conditions.
Further, it is understood that any specific recommendations made in this report as to on-site
construction review by ECS will be authorized and funds and facilities for such review will be
provided at the times recommended if we are to be held responsible for the design
recommendations.
APPENDIX E
PROCEDURES REGARDING FIELD LOGS, LABORATORY TESTING AND SAMPLES
In the process of obtaining and testing samples and preparing this report, procedures are
followed that represent reasonable and accepted practice in the field of soil and foundation
engineering.
Specifically, field logs are prepared during performance of the drilling and sampling operations,
which are intended to portray, in the driller's judgment: field occurrences, sampling locations,
and other information.
Samples obtained in the field are frequently subjected to testing and reclassification in the
laboratory by more experienced soil engineers, and differences between the field logs and the
final logs exist. The engineer preparing the report reviews the field logs, lab classifications, and
test data. Using his judgment in interpreting this data, he may make further changes.
Samples taken in the field are retained in our laboratory for sixty days and are then discarded,
unless special disposition is requested by our client. Samples retained over a long period of
time, even if sealed in jars, are subject to moisture loss which changes the apparent strength of
cohesive soil generally increasing the strength from what was originally encountered in the field.
Since they are then no longer representative of the moisture conditions initially encountered, an
inspection of these samples should recognize this factor.
