Oakland Lake Estates Subdivision Universal Project No. 0330.1700052.0000
Fort Pierce, Saint Lucie County,- Florida Preliminary Subsurface Exploration
1.0 INTRODUCTION
Universal Engineering Sciences, Inc. (Universal) has completed a preliminary subsurface
exploration for the proposed Oakland Lake Estates Subdivision in Fort Pierce, Saint Lucie
County, Florida. Our exploration was authorized by Mr. Michael DeBock of Ryan Homes and
was conducted as outlined in Universal's Proposal No. 0330.0417.00003. This exploration was
performed in accordance with generally accepted soil and foundation engineering practices. No
other warranty, expressed or implied, is made.
2.0 PROJECT DESCRIPTION
It is Universal's understanding, based upon information provided by the client, that the proposed
project will consist of a residential subdivision in Fort Pierce, Florida; currently envisioned as
shown in Figure No. 1. The proposed subdivision is intended to have seventy-three (73)
residential lots.
We understand that the stormwater runoff from impervious surfaces to be developed at this site
will be collected within an existing retention basin located in the central sections of the project
area.
Please note that our subsurface exploration was.prellmina in nature and conducted to acquire
general subsurface information only. Once specified 'site configuration, building detail and
structural and traffic loading information are available a final subsurface exploration should be
performed.
3.0 PURPOSE
The purposes of this exploration were:
to explore the subsurface conditions at general locations and depths as requested by the
client and
to provide our estimates of the typical wet season high groundwater levels at the boring
locations and
to provide general comments concerning the anticipated soil support characteristics for
typical low-rise residential construction.
4.0 SITE DESCRIPTION
The subject site is located within Section 11, Township 34 South, Range 39 East in Saint Lucie
County, Florida. More specifically, the site is located on the northwest quadrant of Palomar
Street Road and North Kings Highway, in Fort Pierce, Florida. At the time of drilling, the site
vegetation consisted of mostly grass, along with an existing paved circular road around the
proposed subdivision.

Nearly level, poorly drained sandy soils in broad areas in the
flatwoods.
4.2 TOPOGRAPHY
According to information obtained from the United States Geologic Survey (USGS) Oslo, Florida
quadrangle map dated 1949, photo -revised 1970, ground surface elevation across the site area
(pre -developmental) is approximately +20 feet National Geodetic Vertical Datum (NGVD).
5.0 SCOPE OF SERVICES
The services conducted by Universal during our preliminary subsurface exploration program are
as follows:
Drill seven (7) Standard Penetration Test (SPT) borings within the project site area to a
depth of 10 feet below existing land surface (bls).
Core through the existing pavement sections at four (4) locations with a diamond tipped core
drill to ascertain the approximate thickness of the asphaltic surfacing and base course.
Perform Dynamic Cone Penetrometer (DCP) testing within the upper portions of the
selected SPT boreholes to help further determine soil consistencies.
Secure samples of representative soils encountered in the soil borings for review, laboratory
analysis and classification by a Geotechnical Engineer.
Measure the existing site groundwater levels and provide an estimate of the typical wet
season high groundwater levels.
Conduct soil gradation tests on selected soil samples obtained in the field to help determine
their engineering properties.
0 Assess the existing soil conditions with respect to the proposed construction,

subsurface exploration and laboratory testing program with analysis and general comments.
6.0 LIMITATIONS
Please note that this report is based on a preliminary subsurface exploration program with the
scope of services, general boring locations and depths as developed in conjunction with the
client. The information submitted in this report is based on data obtained from the soil borings
performed at the locations indicated on the Boring Location Plan and from other information as
referenced. This report has not been prepared to meet the full needs of design professionals,
contractors, or any other parties, and any use of this report by them without the guidance of the
soil and foundation engineer who prepared it constitutes improper usage which could lead to
erroneous assumptions, faulty conclusions, and other problems.
This report does not reflect any variations which may occur across the site. The nature and
extent of such variations may not become evident until the course of future explorations or
actual construction. If variations then become evident, it will be necessary for re'evaluation of
the recommendations in this report after performing on -site observations during the construction
period and noting the characteristics of any variations. Deleterious soils were not encountered
at any of our boring locations; however, we cannot completely preclude their presence across
the entire property. Therefore, this report should not be used for estimating such items as cut
and fill quantities.
Our field exploration did not find unsuitable or unexpected materials at the time of occurrence.
However, borings for a typical geotechnical report are widely spaced and generally not sufficient
for reliably detecting the presence of isolated, anomalous surface or subsurface conditions, or
reliably estimating unsuitable or suitable material quantities. Accordingly, Universal does not
recommend relying on our boring information to negate presence of anomalous materials or for
estimation of material quantities unless our contracted services specifically include sufficient
exploration for such purpose(s) and within the report we so state that the level of exploration
provided should be sufficient to detect such anomalous conditions or estimate such quantities.
Therefore, Universal will not be responsible for any extrapolation or use -of our data.by others
beyond the purpose(s) for which it is applicable or intended.
A[[ users of this report are cautioned that there was no requirement for Universal to attempt to
locate any man-made buried objects or identify any other potentially hazardous conditions that
may exist at the site during the course of this exploration. Therefore no attempt was made by
Universal to locate or identify such concerns. Universal cannot be responsible for any buried
man-made objects or environmental hazards which may be subsequently encountered during
construction that are not discussed within the text of this report. We can provide this service if
requested.
For a further description of the scope and limitations of this report please review the document
attached within Exhibit 1 "Important Information About Your Geotechnical Engineering Report'
prepared by GBA/The Geoprofessional Business Association.

7.0 FIELD METHODOLOGIES
7.1 STANDARD PENETRATION TESTS
The seven (7) SPT borings, designated B1 through B7 on the attached Figure No. 1, were
performed in general accordance with the procedures of ASTM D 1586 (Standard Method for
Penetration Test and Split -Barrel Sampling of Soils). The SPT drilling technique involves driving
a standard split -barrel sampler into the soil by a 140 pound hammer, free falling 30 inches. The
number of blows required to drive the sampler 1 foot, after an initial seating of 6 inches, is
designated the penetration resistance, or N-value, an index to soil strength and consistency.
The soil samples recovered from the split -barrel sampler were visually inspected and classified
in general accordance with the guidelines of ASTM D 2487 (Standard Classification of Soils for
Engineering Purposes [Unified Soil Classification System]).
The SPT soil borings were performed with a CME 45 ATV mounted drilling rig. Universal located
the test borings in the field by using the provided site plan and by plotting in the field with a
Garmin GPS receiver. No survey control was provided on -site, and our boring locations should
be considered only as accurate as implied by the methods of measurement used. The
approximate boring locations are shown on the attached Figure No. 1.
7.2 DYNAMIC CONE PENETROMETER TESTS
bynamic Cone Penetrometer (DCP) tests were performed within the upper portions of the
selected SPT boreholes to help further determine soils consistencies. The DCP tests were
performed at 1 foot intervals in general accordance with the procedures developed by Professor
G. F. Sowers and Charles S. Hodges (ASCE, 1966). The basic procedure for the DCP test is as
follows: A standard 1.5 inch diameter conical point is driven into the soil by a 15-pound steel
hammer falling 20 inches. FolloWing the seating of the point to a depth of 2 inches, the number
of blows required to drive the sampler an additional 1.75 inches is designated the penetration
resistance, providing an index to soil strength and density.
7.3 PAVEMENT CORE SAMPLES
Samples of the existing asphaltic pavement sections were obtained at four (4) core locations
(Cl through C4) with a 4 inch nominal diameter diamond bit core drill, advancing through the
asphaltic pavement into the underlying base course materials. Afterwards the core holes were
backfilled and the surfacing patched with an asphaltic "cold patch" mixture and the core samples
returned to our laboratory for subsequent examination.
8.0 LABORATORY METHODOLOGIES
8.1 PARTICLE SIZE ANALYSIS
We completed #200 sieve particle size analyses on seven (7) representative soil samples.
These samples were tested according to the procedures listed ASTM D 1140 (Standard Test
Method for Amount of Material in Soils Finer than the No. 200 Sieve). In part, ASTM D 1140
requires a thorough mixing the sample with water and flushing it through a No. 200 sieve until all
of the particles smaller than the sieve size leave the sample.

The percentage of the material finer than the No. 200 sieve helps determines the textural nature
of the soil sample and aids in evaluating its engineering characteristics. The percentage of
materials passing the #200 sieve is shown on the attached boring logs.
9.0 SOIL STRATIGRAPHY -
The results of our field exploration and laboratory analysis, together with pertinent information
obtained from the SPT borings, such as soil profiles, penetration resistance and stabilized
groundwater levels are shown on the boring logs included in Appendix A. The Key to Boring
Logs, Soil Classification Chart is also included in Appendix A. The soil profiles were prepared
from field logs after the recovered soil samples were examined by a Geotechnica( Engineer.
The stratification lines shown on the boring logs represent the approximate boundaries between
soil types, and may not depict exact subsurface soil conditions. The actual soil boundaries may
be more transitional than depicted. A generalized profile of the soils encountered at our boring
locations is presented in the following Table 11. For more detailed soil profiles, please refer to the

10.0 GROUNDWATER CONDITIONS
10.1 EXISTING GROUNDWATER CONDITIONS
We measured the water levels in the boreholes on May 8, 2017 after the groundwater was
allowed to stabilize. The groundwater levels are shown on the attached boring logs. The
groundwater level depths ranged from 4.3 feet bls at boring location B6 to 5.7 feet bIs at boring
locations B2 and B7. Fluctuations in groundwater levels should be anticipated throughout the
year, primarily due to seasonal variations in rainfall, surface runoff, and other factors that may
vary from the time the borings were conducted.
10.2 TYPICAL WET SEASON HIGH GROUNDWATER LEVEL
The typical wet season high groundwater level is defined as the highest groundwater level
sustained for a period of 2 to 4 weeks during the "wet" season of the year, for existing site
conditions, in a year with average normal rainfall amounts. Based on historical data, the rainy
season in Saint Lucie County, Florida is between June and October of the year. In order to
estimate the wet season water level at the boring locations, many factors are examined,
including the following:
a. Measured groundwater level
b. Drainage characteristics of existing soil types
C. Season of the year (wet1dry season)
d. Current & historical rainfall data (recent and year-to-date)
e. Natural relief points (such as lakes, rivers, swamp areas, etc.)
f, Man-made drainage systems (ditches, canals, etc.)
9. Distances to relief points and man-made drainage systems

h. On -site types of vegetation
L Area topography (ground surface elevations)
Groundwater level readings were taken on May 8, 2017. According to data from the Southeast
Regional Climate Center and the National Weather Service, the total rainfall in the previous
month of April for Central Saint Lucie County was 2.2 inches, approximately a�.the normal levels
for the month of April. Year4oAite rainfall for 2017 through May 8 th was approximately 6%
inches, roughly 6 inches below the normal level for this time period.
Based on this information and factors listed above, we estimate that the typical wet season high
groundwater levels at the boring locations will be approximately 2% feet above the existing
measured levels. Please note, however, that peak stage elevations immediately following
various intense storm events, may be somewhat higher than the estimated typical wet season
levels.
Due to the variable silt and clay content within the near surface soils at this site, we suspect that
there may be occasional isolated pockets of "perched" groundwater throughout the project area,
particularly during periods of prolonged wet weather. These temporary perched water table
levels may be higher than the estimated wet season high groundwater levels indicated above.
11.0 LABORATORY RESULTS
11.1 PARTICLE SIZE ANALYSIS
The soil samples submitted for analysis were classified as fine sands [SPI. The percentage of
soil sizes passing the #200 sieve size are shown on the boring logs. at the approximate depth
sampled.
12.0 ANALYSIS AND GENERAL COMMENTS
12.1 PROPOSED BUILDING AREAS
The removalL of site vegetation and roots, along with other construction activities, will further
loosen surficial soils to various depths. To provide a homogeneous, compacted, sandy soil
system underneath the proposed foundations and floor slabs for the proposed residences,
densification of at least the upper 2 feet of the existing surficial, loose soils and subsequent
additional fill soils will be necessary. This should create a soil mat capable of dissipating the
building loads over any remaining loose strata at depth.
We believe that this can be effectively accomplished using conventional site preparation
procedures including a comprehensive root raking and stripping procedure to remove
vegetation, root mats, debris and organic topsoils; and then an extensive proof -rolling and
densification program for the surficial soils and subsequent structural fill. Assuming that such
procedures are properly performed, we an ' ticipate that conventional, shallow spread footing
foundations may be used to support conventional ohigto two story residential ddri§truction.

The Geoprofesslonall Business Association (GBA)
has prepared this advisory to help you — assurnedly
a client representative — Interpret and apply this
geotechnical-angineering report as effectively
as possible. In that way, clients can benefit from
a lowered exposure to th subsurface problems
that, for decades, have been a principal cause of
construction delays, cost overruns, claims, and
disputes. If you have questions or want more
Information about any of the Issues discussed below,
contact your GBA-member geolechnical engineer.
Active Involvement In the Geoprofessional Business
Association exposes geotechnical engineers to a
wide array of risk -confrontation techniques that can
be of genuine benefit for everyone Involved with a
construction project.
Geotechnical-Engineering Services Are Performed for
Specific Purposes, Persons, and Projects
Geotechnicad engineers structure their services to meet the specific
needs of their clients. A gmtechnical-enginecring study conducted
for a given civil engineer will not likely meet the needs of a civil -
works constructor or even a diffiorent civil engineer. B ecause each
geotedinical-engineering study is unique� each geotechnical-
engineering report is uniquc� prepared solely for the client Rose who
rely on a geofechnical-engineering report preparedfor a different client
can be seriously misted. No one except authorized client representatives
should rely a n this geotechnical-engineering report without first
conferring with the geotechnical engineer who prepared it. And no one
- not even you - should apply this mportfor any purpose or project except
the one originaly contemplated.
Read this Report In Full
Costly problems have occurredbecause those relying onagentechnical-
engineering report did not mad it in its entimty. Do not rely on an
executive summary Do not mad selected elements only. Read this nport
infull.
You Need to Inform Your Geotechnlcal Engineer
about Change
Your geotechnical engineer considered unique, project -specific factors
when designing the study behind this report and developing the
confirmation -dependent recommendations the report conveys, A few
typical factors include:
• the clients goals, objectives, budget, schedule, and
risk-managernent imcferences;
• the general nature of the structure involved, its size,
configuration, and performance criteria;
• the structurds location and orientation on the site, and
• other planned or existing site improvements, such as
retaining yvaU access roads, parking lots. and
urulerground utilities.
Typical changes that could erode the reliability of this report include
tbos�Ta! affect:
C SLteS size or shape;
• the function of the proposed structure, as when ifs
changed from a parking garage to an office building, or
from a fight -industrial plant to a refrigerated warehouse;
• the elevation, configuration, location, orientation, or
weight of the proposed structure,
• the composition of the design team; or
• project ownership.
As a general rule, always infiamn your geatechnical engineer of project
changes - even, minor ones - and request an assessment of their
impact. 7he geotechnical engineer who prepared this report cannot accept
responsibility or liabilityfor problems that arise because the geotechnical
engineer was not informed about developments the engineer otherwise
would haw considered
This Report May Not Be Reliable
Do not rely on this report if your geotecbmical engineer prepared it;
• for a different client;
• for a different project;
• for a different site (that may or may not include all or a
portion of the original site); or
• before important events occurred at the site or adjacent
to it; e.g., man-made events like construction or
environmental mcnediation, or natural events like floods,
droughts, earthquakes, or groundwater fluctuations.
Note. too, that it could be unwise to rely on a geotedinical-engineering
report whose reliability may have been affected by the passage of time,
because of factors like changed subsurface conditions; new or modified
codes, standards. or regulations; or new techniques or tools. Ifyour
geotechnical engineer has not indicated an lzppy-by" date on the report,
ask what it should be, and, in general, ifyou am the least bit uncertain
about the continued reliability of this report, contact your geotechnical
engineer before applying it. A minor annount of additional testing or
analysis - if my is required at all - could prevent major problems.
Most of the "Findings" Related in This Report Are
Professional Opinions
Before construction begins. geotechnical engineers explore a slide
subsurface through various sampling and testing procedures.
Geotechnical engineers can observe actual subsurface conditions only at
those specific locations where sampling and testing were performed. The
data derived from that sampling and testing were reviewed by your
geotechnical engineer, who then applied professional judgment to
form opinions about subsurface conditions throughout the site. Actual
sitewide-sabsurFace conditions may differ - maybe significantly - from
those indicated in this report. Cordmnt that risk by retaining your
geotechnical engineer to serve on the design team firom project start to
pmject finish, so the individual can provide infiamned guidance quickly,
wheneve I needed
This Report's Recommendations Are
Confirmation -Dependent
The recommendations included in this report - including any options
or alternatives - we confirmation -dependent. In other words, they are
notfinal, because the geotechnical engineer who developed them relied
heavily on judgment and opinion to do so. Your geotechnical engineer
can finalize the mcommenclations; only after observing actual subsurface
conditions revealed during construction. If through observation your
geotechnical engineer confirms that the conditions assume d to exist
actually do exist, the recommendations can be relied upon, assuming
no other changes have occurred. 7he geotechnical engineer who prepared
this report cannot assume responsibility or Itabilityfor confirmation -
dependent recommendations ifyoufait to retain that engineer to perform
construction observation.
This Report Could Be Misinterpreted
Other design professions& misinterpretation of gentechnical-
engineering reports has resulted in costly problems. Confront that risk
by having your geotechnical engineer serve as a full-time member of the
design team, to:
• confer with other design-tem members,
• help develop specifications,
• review pertinent elements of other design professionals'
plans and specifications, and
• be on hand quickly whenever geotechnical-engineering
guidance is needed.
You should also confront the risk of constructors misinterpreting this
report Do so by retaining your geotechnical engineer to participate in
p=b1d and preconstructiont conferences and to perform construction
observation.
Give Constructors a Complete Report and Guidance
Some owners and design professionals mistakenly believe they can shift
unmticipated-subsurface-conditions liability to constructors by limiting
the information they provide for bid preparation. To help prevent
the costly, contentious problems this practice has caused, include the
complete geortechnical-engineering report, along with any attachments
or appendices, with you contract documents, but be certain to note
conspicuo usly that you've included the materialfor infornuitional
purposes only. To avoid misunderstanding, you may also want to note
that "informational purposee means constructors have no right to rely
on the interpretations, opinions, conclusions, or recommendations in
the report,but they may rely on the factual data relative to the specific
times, locations, and depths/elevations referenced. Be certain that
constructors know they may learn about specific project requirements,
including options selected from the report, only from the design
drawings and specifications. Remind comtructors that they may
SABA
perform their own studies if they want to, and be sun to allow enough
time to permit them to do so. Only then might you be in a position
to give constructors the information available to you, while requiring
them to at least share some of the financial responsibilities stemming
from unanticipated conditions. Conducting prebld and preconstruction
conferences can also be valuable In this respect.
Read Responsibility Provisions Closely
Some client representatives, design professionals. and constructors do
not realize that geotechnicad engineering is far less exact than other
engineering disciplines. That lack of understanding has nurturcul
unrealistic expectations that have resulted in disappointments, delays,
cost overruns, claims, and disputes. To confront that risk, geotechnical
engineers commonly include explanatory provisions in their reports.
Sometimes labeled "Hinitations:'many of these provisions indicate
where gentechnical engineers' responsibilities begin and end, to help
others recognize their own responsibilities and risks. Read thes;e
provisions closely. Ask questions. Your geotechnical engineer should
respond fully and frankly.
Geoenvironmental Concerns Are Not Covered
7he personnel, equipment, and techniques used to perform an
environmental study - e.g., a "phase -one' or "phase-twd'environmental
site assessment - differ significantly from those used to perform
a gemechnical-engincering study. For that reason. a geotechnical-
engineering report does not usually relate any environmental findings,
conclusions, or recommendations; e.g., about the likelihood of
encountering underground storage tanks or regulated contaminants.
Unanticipated subsurface envirommentalproblems have led to project
failures. If you have not yet obtained yaw own environmental
information, ask your geoteclurtical consultant for risk-mamagement
guidance. As a general role. do not rely on an environmental report
preparedfor a different client, site, or project, or that is more than six
months old.
Obtain Professional Assistance to Deal with Moisture
Infiltration and Mold
While your geotechnical engineer may haw addressed groundwater,
water infiltration, or similar issues in this report, none of the engineer's
services were designed, conducted, or intended to prevent uncontralled
migration of moisture - including water vapor - from the soil through
building slabs and walls; and into the building interior, where it can
cause mold growth and material -performance dcficicncies. Accordingly,
proper implementation of the geotechnical engineer's recommendations
will no t of itsey'bc sufficient to prevent mo istum infiltration. Confront
the risk of moisture infiltration by including building-envclopc or mold
specialists on the design team. Geatechnical engineers am not building -
envelope or moldspecialists.
