Oakland Lake Estates Subdivision
Fort. Pierce; Saint Lucie County, Florida
Universal Project No. 0330.1700052.0000
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.,,pre(iHriarv; 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 oh 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.

Preliminary, Subsurface Exploration
4.1 SOIL SURVEY -
Two (2) soil types are mapped within the general project area according to the Saint Lucie
County Soil Survey (SLCSS), dated 1980. A brief description: of these soils' is provided in the
following Table.1.

'shallow depressions, and swamps:.
"Nearly level, poorly drained sandysoils.in, broad areas in the
Wabasso sand (4.8) - I1 ! 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_
(pte-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:
r ,
• 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 Geotechnioal Engineer.
• Measure the existing site groundwater levels and provide an estimate of the typical wet
season high groundwater levels.
4 Conduct soil gradation tests on selected soil samples obtained in the field to help determine
their engineering properties.
• Assess the existing soil conditions with respect to the proposed construction.

Preliminary Subsurface Exploration
• Preparing a geotechnical engineering report which documents the results of our preliminary
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 shouldr 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 reportwe 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.
All users of this report are cautioned that there was no requirement for Universal to attempt to
locate any man-made buried objects o� 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
Universal Project No. 0330.1700052. 0000
Preliminary Subsurface Exploration
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 r
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
Dynamic 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. Hedges (ASCE, 1966). The basic procedure for the DCP testis 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 1.76 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 4
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 Geotechnical• 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 bis at boring location B6 to 5.7 feet bls af• 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
bi. Drainage characteristics of existing soil types
C. Season of the year (wet/dry season)
0,. 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.)
g. Distances to relief points and man-made drainage systems

h,, On -site types of vegetation
i. Area topography (ground surface elevations):
Groundwater level readings were taken on May 8, 2017. According to data #rom'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 0-:normal levels
for the month of. April. Year-to=date rainfall for 2017 through May 8'h 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'/z 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 [SP]. The percentage of
soil sizes passing the #200 sieve size are shown on the boringlogs at the approximate depth
sampled.
12.0 ' ANALYSIS AND GENERAL COMMENTS
12.1 PROPOSED BUILDING AREAS
The removal. 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 anticipate that conventional, shallow spread footing
foundations may. be used to support conventio`nal_one;;to" two sfoiv residentr"al construction':

Gco�eho�al-E�gi�eeri�g Report
lit T e Geoprofessional Business Association (GBA)
h s prepared this advisory to help you — assumedly
a Client representative —.interpret and'appiy this
g otechnical-engineering report as effectively
a possible:'ln that way, clients can benefit from
a lowered exposure to the subsurface problems
t at, for decades; have been a principal cause of
nstructiondelays, cost overruns, claims, -and
lisputes. 1f you have questions or want more
I formation- about any of the issues discussed below,
intact your GBA-member.geotechnical engineer.
ctive involvement in the Geoprofessional Business
{ssociation exposes'geotechnical engineers•to a
I' ide array, of risk -confrontation techniques that can
e of genuine benefit for everyone involved with. a
J', construction project.
i
eotechnical-Engineering Services Are Performed for
pecific.Purposes, Persons, and Projects
eotechnical engineers structure their services to meet the specific
deeds of their clients, A geotechnical-engineering study conducted
r a given civil engineer will not likely meet the needs of a civil-
; orks constructor or even a different civil engineer. Because each
eotechnical-engineering study is unique, each geotechnical-
gineering report is unique, prepared solely for the client. Those who
iy on a geotechnical-engineering report prepared for a different client
n be seriously misled. No one except authorized client representatives
hould rely on this geotechnical-engineering report without first
onferring with the geotechnical engineer who prepared it. And no one
not even you - should.apply this report for any purposeor project except
�he one originally contemplated.
Read this Report in Full
Cosily problems have occurred because those relying on a geotechnical-
engineering report did not read it in its entirety. Do not rely on an
executive summary. Do not read selected elements only. Read this report
n full.
I
Yo
u Need)to`lnform Your Geotechnical Engineer
about Change
our geotechnical engineer considered unique, project -specific factors
✓hen designing the study behind this report and developing the
confirmation=dependent recommendations the report conveys. A few
typical factors include:
the client's goals, objectives,'budget, schedule, and
risk -management preferences;
• the general nature of the structure involved, its size,
jconfiguration, and performance criteria;
i the structure's location and orientation on the site; and
other planned or existing site improvements, such as
• re$41fi g walls, access roads, parking lots, and
unileXgiound utilities.
Typical changes that could erode the reliability of this report include
those that affect -
the sites size or shape;
• the function of the proposed structure, as when it's
changed from a parking garage to an office building, or
from a light -industrial plant to a refrigerated warehouse;
• the elevation, configuration, location, orientation, or i
weight of the proposed structure;
• _ the composition of the design team; or
• project ownership.
i�
As a general rule; always inform your geotechnical engineer of project
changes - even minor ones - and request an assessment of their
impact. The geotechnical engineer who prepared this report cannot accept
responsibility or liability for problems that arise because the geotechnical
engineer was not informed about developments the engineer otherwise
would have considered. `
This Report -May Not Be Reliable
Do not rely on this report if your geotechnical engineer prepared it:
• for a different client;
• for a different project;
• for a different site (that may or may not include all or a I ; • '
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 remediation, or natural events like floods,
droughts, earthquakes, or groundwater fluctuations.
Note, too, that it could be unwise to rely on a geotechnical-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. If your
geotechnical engineer has not indicated an `apply -by" date on the report
ask what it should be, and, in general, if you are the least bit uncertain
about the continued reliability of this report, contact your geotechnical
engineer before applying it. A minor amount of additional testing or
analysis - if any is required at all - could prevent major problems.
l ,
Most of the "Findings" Related,in This Report Are
Professional:Opin ions
Before construction begins, geotechnical engineers explore a site's "
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 1 I„
form opinions about subsurface conditions throughout the site. Actual
sitewide-subsurface conditions may.differ - maybe significantly - from
those indicated in this report. Confront that risk by retaining your
geotechnical engineer to serve on the design team from project start to
project finish, so the individual can provide informed guidance quickly, r ;'
wheneve needed.
i
Report's Recommendations Are
recommendations included in this report - including any options
lternatives - are confirmation -dependent. In other words, they are
final, because the geotechnical engineer who developed them relied
rily on judgment and opinion to do so. Your geotechnical engineer
finalize the recommendations only after observing actual subsurface
iitions revealed during construction. If through observation your
:echnical engineer confirms that the conditions assumed to exist
.ally do exist, the recommendations can be relied upon, assuming
>ther changes have occurred. The geotechnical engineer who prepared
report cannot assume responsibility or liability for conftrmation-
,ndent recommendations if you fail to retain that engineer to perform
ttruction observation.
Report Could Be Misinterpreted
design professionals' misinterpretation of geotechnical-
!ering reports has resulted in costly problems. Confront that risk
ing your geotechnical engineer serve as.a full-time member of the
d Sign team, to:
confer with other design -team 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.
0
should also confront the risk of constructors misinterpreting this
,rt. Do so by retaining,your geotechnical engineer to participate in
id and preconstruction conferences and to perform construction
ve Constructors a Complete Report and Guidance
ne owners and design professionals mistakenly believe they can shift
mticipated-subsurface-conditions liability to constructors by limiting
information they provide for bid preparation. To help prevent
costly, contentious problems this practice has caused, include the
nplete geotechnical-engineering report, along with any attachments
appendices, with your contract documents, but be certain to note
spicuously that you've included the material for informational
poses only. To avoid misunderstanding, you may also want to note
t "informational purposes" means constructors have no right to rely
the interpretations, opinions, conclusions, or recommendations in
report, but they may rely on the factual:data relative to the specific
yes, locations, and depths/elevations referenced._ Be certain that
istructors know they may learn about specific project requirements,
luding options selected from the report, only from the design
wings and specifications. Remind constructors that they may
perform their own studies if they want to, and be sure 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 prebid 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 geotechnical engineering is far less exact than other
engineering disciplines. That lack of understanding has nurtured
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 "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.
Geoenvironmental Concerns Are Not Covered
The personnel, equipment, and techniques used to perform an
environmental study -e.g., a "phase -one' or "phase -two' environmental
site assessment - differ significantly from those used to perform
a geotechnical-engineering 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 environmental problems have led to project
failures. If you have not yet obtained your own environmental
information, ask your geotechnical consultant for risk -management
guidance. As a general rule, do not rely on an environmental report
prepared for 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 have addressed groundwater,
water infiltration, or similar issues in this report, none of the engineer's
services were designed, conducted, or intended to prevent uncontrolled
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 deficiencies. Accordingly,
proper implementation of the geotechnical engineer's recommendations
will not of itself be sufficient to prevent moisture infiltration. Confront
the risk of moisture infiltration by including building -envelope or mold
specialists on the design team. Geotechnical engineers are not building -
envelope or mold specialists.
