3.0 FIELD EXPLORATION
3.1 FIELD EXPLORATION PROGRAM
The field exploration was planned with the objective of obtaining samples to perform the
requested laboratory tests.
3.1.1 Vibracore Samples
Three (3) vibracore samples (Zone 1, Zone 2, and Zone 4) were obtained at the existing lake at
approximately 12 feet below the waterline. The approximate test locations are shown on the
attached exploration diagram.
3.1.2 Grab Samples
Three (3) grab samples (Sp-1 through Sp-3) were taken at the stockpiled soil that was dredged
from the existing lake and stored at the Carolina Beach water department
3.2 REGIONAL/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 nearthe 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.
Based on the U.S. Geological Survey1,2 the site of the proposed construction lies within the
Surficial Deposits (Qp) geologic formation. The formation generally consists of alluvial sands, silts
and clayss. An overview of the general site geology is illustrated in Figure 3.2.1 below.

Survey, in cooperation with the NC Center for Geographic Information and Analysis, 1998, Geology - North Carolina

4.0 LABORATORY TESTING
October9, 2017
Page 6
The laboratory testing performed by ECS for this project consisted of selected tests performed on
samples obtained during our field exploration operations. The following paragraphs briefly
discuss the results of the completed laboratory testing program.
Bulk soil samples were obtained at depths ranging from approximately 1 to 3 feet below the
existing ground surface and were subjected to moisture (ASTM D2974-87), pH (EPA 9045) sulfide
soil (SM 4500-S2d), sulfate ion (ASTM D 516-16) and chloride ion (ASTM D 512-12) testing. The
corrosion series testing results are shown in Table 4.1 below.
• Perform six (6)TPH —GRO tests (SW-846 5030+8015)
• Perform six (6)TPH — DRO tests (SW-846 3550/8015)
• Perform six (6) SVOCs tests (EPA 625 / SW-846 8270D)
• Perform six (6) BETEX screens (8260)
• Perform six (6) RCRA Metals test (SW-846 6010 7470 / 7471)
• Perform six (6) Hexavalent Chromium tests (SM 3500 CRD / SW-846 7196)
• Perform six (6) TCL Volatile Organics tests (SW-846 8260)

5.0 SITE CONSTRUCTION RECOMMENDATIONS
Unsatisfactory Materials: Unsatisfactory fill materials include materials which to not satisfy the
requirements for suitable materials, as well as topsoil and organic materials (OH, OL), elastic Silt
(MH), and high plasticity Clay (CH) as encountered in Zone 1 and Zone 2 of the lake. The CEC can
consider allowing soils these soils to be used as Structural Fill at depths greater than 4 feet below
pavement subgrades outside the expanded building limits and within non-structural areas.
On -Site Borrow Suitability: Most materials contained within the on -site stockpiles as well as Zone
4 of the lake are expected to be suitable for use as fill. Limited moisture conditioning of the fill
lifts will be required to achieve compaction for the soils from the stockpile. Moisture conditioning
of the material of Zone 4 will be required priorto anyfill placement.
Chemical Analysis: Based on the laboratory analysis, the samples tested positive for DROs,
arsenic, barium, chromium, lead, mercury. Based on the Inactive Hazardous Sites Branch (IHSB)
Preliminary Residential Health Based Soil Remediation Goal, the laboratory analysis detected
levels of arsenic above the IHSB PSRG values. Arsenic can typically occur naturally at elevated
levels above the IHSB levels.

6.0 CLOSING
ECS has prepared this report of findings, evaluations, and recommendations to guide
geotechnical-related design and construction aspects of the project.
The description of the proposed project is based on information provided to ECS by SEPI. If any of
this information is inaccurate, either due to our interpretation of the documents provided or site
or design changes that may occur later, ECS should be contacted immediately so that we can
review the report in light of the changes and provide additional or alternate recommendations as
may be required to reflect the proposed construction.
We recommend that ECS be allowed to review the project's plans and specifications pertaining to
our work so that we may ascertain consistency of those plans/specifications with the intent of the
geotechnical report.
Field observations, monitoring, and quality assurance testing during earthwork and foundation
installation are an extension of and integral to the geotechnical design recommendation. We
recommend that the owner retain these quality assurance services and that ECS be allowed to
continue our involvement throughout these critical phases of construction to provide general
consultation as issues arise. ECS is not responsible for the conclusions, opinions, or
recommendations of others based on the data in this report.

1,2-Dipheny1hydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270, The result reported for

ANALYTE QUALIFIERS
1g The internal standard response is below criteria. No hits associated with this internal standard. Results unaffected by
high bias.
D3 Sample was diluted due to the presence of high levels of non -target analytes or other matrix interference.
D6 The precision between the sample and sample duplicate exceeded laboratory control limits.
H3 Sample was received or analysis requested beyond the recognized method holding time.
L2 Analyte recovery in the laboratory control sample (LCS) was below QC limits. Results for this analyte in associated
samples may be biased low.
Mo Matrix spike recovery and/or matrix spike duplicate recovery was outside laboratory control limits.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.
S2 Surrogate recovery outside laboratory control limits due to matrix interferences (confirmed by similar results from sample
re -analysis).
S3 Surrogate recovery exceeded laboratory control limits. Analyte presence below reporting limits in associated sample.
S4 Surrogate recovery not evaluated against control limits due to sample dilution.

APPENDIX C—Supplemental Report Documents
ASFE Document

- Geotechnical Engineering Report -
Geotechnical Services Are Performed for
Specific Purposes, Persons, and Projects
Geotechnical engineers structure their services to meet the specific needs of
their clients. A geotechnical engineering study conducted for a civil engineer
may not fulfill the needs of a construction contractor or even another civil
engineer. Because each geotechnical engineering study is unique, each geo-
technical engineering report is unique, prepared solelyfor the client. No one
except you should rely on your geotechnical engineering report without first
conferring with the geotechnical engineer who prepared it. And no one - not
even you- should apply the report for any purpose or project except the one
originally contemplated.
Read the Full Report
Serious problems have occurred because those relying on a geotechnical
engineering report did not read it all. Do not rely on an executive summary.
Do not read selected elements only.
A Geotechnical Engineering Report Is Based on
A Unique Set of Project -Specific Factors
Geotechnical engineers consider a number of unique, project -specific factors
when establishing the scope of a study. Typical factors include: the client's
goals, objectives, and risk management preferences; the general nature of the
structure involved, its size, and configuration; the location of the structure
on the site; and other planned or existing site improvements, such as access
roads, parking lots, and underground utilities. Unless the geotechnical engi-
neer who conducted the study specifically indicates otherwise, do not rely on
a geotechnical engineering report that was:
• not prepared for you,
• not prepared for your project,
• not prepared for the specific site explored, or
• completed before important project changes were made.
Typical changes that can erode the reliability of an existing geotechnical
engineering report include those that affect:
• the function of the proposed structure, as when it's changed from a
parking garage to an office building, or from alight industrial plant
to a refrigerated warehouse,
• elevation, configuration, location, orientation, or weight of the
proposed structure,
• composition of the design team, or
• project ownership.
As a general rule, always inform your geotechnical engineer of project
changes - even minor ones - and request an assessment of their impact.
Geotechnical engineers cannotaccept responsibility or liability for problems
that occur because their reports do not consider developments of which they
were not informed.
Subsurface Conditions Can Change
A geotechnical engineering report is based on conditions that existed at the
time the study was performed. Do not rely on a geotechnical engineering
report whose adequacy may have been affected by: the passage of time; by
man-made events, such as construction on or adjacent to the site; or by natu-
ral events, such as floods, earthquakes, or groundwater fluctuations. Always
contact the geotechnical engineer before applying the report to determine if it
is still reliable. A minor amount of additional testing or analysis could prevent
major problems.
Most Geotechnical Findings Are Professional
opinions
Site exploration identifies subsurface conditions only at those points where
subsurface tests are conducted or samples are taken. Geotechnical engineers
review field and laboratory data and then apply their professional judgment
to render an opinion about subsurface conditions throughout the site. Actual
subsurface conditions may differ -sometimes significantly from those indi-
cated in your report. Retaining the geotechnical engineer who developed your
report to provide construction observation is the most effective method of
managing the risks associated with unanticipated conditions.
A Repoprs Recommendations Are Not Final
Do not overrely on the construction recommendations included in your re-
port. Those recommendations are not final, because geotechnical engineers
develop them principallyfrom judgment and opinion. Geotechnical engineers
can finalize their recommendations only by observing actual

subsurface conditions revealed during construction. The geotechnical engi-
neer who developed your report cannot assume responsibility or liability for
the report's recommendations if that engineer does not perform construction
observation.
A Geotechnical Engineering Report Is Subject to
Misinterpretation
Other design team members' misinterpretation of geotechnical engineer-
ng reports has resulted in costly problems. Lower that risk by having your
geotechnical engineer confer with appropriate members of the design team
after submitting the report. Also retain your geotechnical engineer to review
pertinent elements of the design team's plans and specifications. Contractors
can also misinterpret a geotechnical engineering report. Reduce that risk by
having your geotechnical engineer participate in prebid and preconstruction
conferences, and by providing construction observation.
Do Not Redraw the Engineer's logs
Geotechnical engineers prepare final boring and testing logs based upon
their interpretation of field logs and laboratory data. To prevent errors or
omissions, the logs included in a geotechnical engineering report should
never be redrawn for inclusion in architectural or other design drawings.
Only photographic or electronic reproduction is acceptable, but recognize
that separating logs from the report can elevate risk.
Give Contractors a Complete Report and
Guidance
Some owners and design professionals mistakenly believe they can make
contractors liable for unanticipated subsurface conditions by limiting what
they provide for bid preparation. To help prevent costly problems, give con-
tractors the complete geotechnical engineering report, but preface it with a
clearly written letter of transmittal. In that letter, advise contractors that the
report was not prepared for purposes of bid development and that the report's
accuracy is limited; encourage them to confer with the geotechnical engineer
who prepared the report (a modest fee may be required) and/or to conduct ad-
ditional study to obtain the specific types of information they need or prefer.
A prebid conference can also be valuable. Re sure contractors have sufficient
timeto perform additional study. Only then mightyou be in a position to give
contractors the best information available to you, while requiring them to at
least share some of the financial responsibilities stemming from unantici-
pated conditions.
Read Responsibility Provisions Closely
Some clients, design professionals, and contractors do not recognize that
geotechnical engineering is far less exact than other engineering disciplines.
This lack of understanding has created unrealistic expectations that have led
to disappointments, claims, and disputes. To help reduce the risk of such
outcomes, geotechnical engineers commonly include a variety of explanatory
provisions in their reports. Sometimes labeled "limitations" many of these
provisions indicate where geotechnical engineers' responsibilities begin
and end, to help others recognize their own responsibilities and risks. Read
these provisions closely. Ask questions. Your geotechnical engineer should
respond fully and frankly.
Geoenviponmental Concerns Are Not Covered
The equipment, techniques, and personnel used to perform a geoenviron-
mental study differ significantly from those used to perform a geotechnical
study. For that reason, a geotechnical engineering report does not usually re-
late any geoenvironmental findings, conclusions, or recommendations; e.g.,
about the likelihood of encountering underground storage tanks or regulated
contaminants. Unanticipated environmental problems have led to numerous
project failures. If you have not yet obtained your own geoenvironmental in-
formation, ask your geotechnical consultant for risk management guidance.
Oo not rely on an environmental report prepared for someone else.
Obtain Professional Assistance b Deal with Mold
Diverse strategies can be applied during building design, construction, op-
eration, and maintenance to prevent significant amounts of mold from grow-
ing on indoor surfaces. To be effective, all such strategies should be devised
for the express purpose of mold prevention, integrated into a comprehensive
plan, and executed with diligent oversight by a professional mold prevention
consultant. Because just a small amount of water or moisture can lead to
the development of severe mold infestations, a number of mold prevention
strategies focus on keeping building surfaces dry. While groundwater, wa-
ter infiltration, and similar issues may have been addressed as part of the
geotechnical engineering study whose findings are conveyed in -this report,
the geotechnical engineer in charge of this project is not a mold prevention
consultant; none of the services performed in connection wim
the geotechnical engineers study were designed or conducted
for the purpose of mold prevention. Proper implementation of
Me recommendations conveyed in this report will not of itself
he sufficient to prevent mold from growing in or on the struc-
ture involved.
