(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 Qreliiriinaru in nature and conducted to acquire -general subsurface information only. Once specified -sire 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 ----------- -- ----. _ .... lociatiohs and- - .to provide general comments conceming the anticipated soil support characteristics for typical low-rise residential construction. 4.0 SITE DESCRIPTION County, Florida. More specifically, the Street Road and North Kings Highway vegetation consisted of mostly grass, proposed subdivision. n 11, l ownship 34 South, Range 39 East in Saint Lucie site is located on the northwest quadrant of Palomar in Fort Pierce, Florida. At the time of drilling, the site along with an existing paved circular road around the 820 Brevard Avenule, Rockledge, Florida 32955 (321) 638-0808 Fax (321)1638-0978 www.UniversaIEngineering.com Oakland Lake Estates Subdivision Universal Project No. 0330.1700052.0000 Fort Pierce, Saint Lucie County, Florida 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 I. TABLE SLCSS DESIGNATED SOIL TYPES Soil Type (Map Symbol) _ Brief Description ; Soil material that has been dug up from several areas with different Arents, 0 to 5 percent slopes (4) kinds of soil. It is used to fill up areas such as low sloughs, marshes, shallow depressions, and swamps. Wabasso sand (48) 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. qi 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. • Assess the existing soil conditions with respect to the proposed construction. 2 820 Brevard Avenue, Rockledge, Florida 3255 (321) 638-0808 Fax (321) 638-0978 www.UniversalEngineering.com Oakland Lake Estates Subdivision Universal Project No. 0330.1700052.0000 Fort Pierce, Saint Lucie County, Florda 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 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. All 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-ifrequested. 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. 3 820 Brevard Avenue, Rockledge, Florida 32955 (321) 638-0808 Fax{321) 638-0978 www.UniversalEngineering.com Oakland Lake Estates Subdivision Universal Project No. 0330.1700052.0000 Fort Pierce; Saint Lucie County, Florida Preliminary Subsurface Exploration 7.0 FIELD METHODOLOGIES 7.1 STANDARD PENETRATION TESTS The seven (7) SPT borings, designated 131 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 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 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 ____ofthe particles_smallerthan_thesieve_size_leave_tbe_sample.___--___.___ 4 820 Brevard Avenue, Rockledge, Florilda 32955 (321) 638-0808 Fax (321) 638-0978 www.UniversalEngineering.com Oakland Lake Estates Subdivision Universal Project No. 0330.1700052.0000 Fort Pierce, Saint Lucie County, Florida Preliminary Subsurface Exploration 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 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 II.

The B6 to 5.7 feet bls at boring anticipated throughout the and other factors that may 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.

On -site types of vegetation I. 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 at the normal levels for -the month of April: Year-toAate rainfall for 2017 through May 8'" was approximately "6Y2 - — 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 boring logs 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 sumcial, 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_effectivety_accomplished-using_conventiona"ite—preparation procedures including a comprehensive root raking and stripping procedure to remove vegetation, root matsi debris and organic topsoils; and then an extensive proof -rolling and densification program for the sumcial 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 conventional ohe to two st6N residentialdoiistiuction. 7 8k Brevard Avenue, Rockledge, Florida 32955 (321) 636-0808 Fax (321) 638-0978 www.UniversalEngineering.com Oakland Lake Estates Subdivision Universal Project No. 0330.1700052.0000 Fort Pierce, Saint Lucie County, Florida Preliminary Subsurface Exploration 13.0 CLOSURE We appreciate this opportunity to be of service as your geotechnical consultant on this phase of the project and look forward to providing follow up explorations and geotechnical engineering analyses as the project progresses through the design phase.

APPENDIX A.1 u EXHIBIT 1 r Geolech-nicellopmee-ring Re plopt The Geoprofessional Business Association.(GBA) has prepared this advisory to help you — assumedly a client representative — interpret and apply this geotechnical=engineering report as effectively as possible. In that way, clients can benefit from a lowered exposure to the 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 geotechnical engineer. Active Involvement in the Geoprofessional Business Association exposesgeotechnical 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 Geotechnical engineers structure their services to meet the specific needs of their clients. A geotechnical-engineering study conducted for a given civil engineer will not likely meet the needs of a civil - works constructor or even a different civil engineer. Because each geotechnical-engineering study is unique,. each geotechnical- engineering report is unique, prepared safety for the client Those who rely on a geotechnical-engineering report prepared fora different client can be seriously misted. No one except authorized client representatives should rely on this geotechnical-engineering report without first conferring with the geotechnical engineer who prepared it. And no one - not even you - should apply this report for anypurpose or project except the one originafty contemplated Read this Report In Full Costly problems have occurred because those relying on a geatechnical- executive summary. Do not read selected elements only. Read this report in full. You Need -to Inform Your Geotechnical 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 dienfs goals objectives, budget, schedule, and _ - - risk -management preferences; • the general nature of the structure involved, its size, configuration, and performance criteria; • the structures location and orientation on the site; and • other planned or existing site improvements, such as retaining walls, access roads, parking lots, and underground 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 gangs to an office building, or from a light -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 inform your geotechnical engineer of project changes - even minor ones - and request an assessment of their impact. lire 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 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. Ifyour 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 vour eeotechnical - could prevent major problems. Most of the "Findings" Related in This Report Are Professional Opinions Before construction begins, geotechnical engineers explore a sites subsurface through various sampling and testing procedures. Geotechnical engineers can observe actual subsurface conditions only at those specific locations when sampling and testing were performed. The data derived from that sampling and testing were reviewed by your _geotechnical engineer, who-thenapplied professional judgment to -- 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, wbene7 needed. This Report's Recommendations Are Confirmation -Dependent The recommendations included in this report- including any options or alternatives - are confirmation -dependent In other words, they are not final, because the geotechnical engineer who developed them relied heavily on judgment and opinion to do so. Your geotechnical engineer can finalize the recommendations only after observing actual subsurface conditions revealed during construction. If through observation your geotechnical engineer confirms that the conditions aassumed to exist actually do exist, the recommendations can be relied upon, assuming no other changes have occurred. The geotechnical engineer who prepared this report cannot assume responsibility or liability for confirmation - dependent recommendations ifyou fall to retain that engineer to perform construction observation. This Report Could Be Misinterpreted Other design professionals misinterpretation of geotechnical- 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 -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 lt You should also confront the risk of constructors misinterpreting this report ur Do so by retaining yaw geotechnical engineer to participate in prebid and preconstruction conferences and to perform construction iobservation. Give Constructors a Complete Report and Guidance Some owners and design professionals mistakenly believe they can shift unanticipated -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 geotechnical-engineering report, along with any attachments or appendices, with your contract documents, but be certain to note conspicuously that you've included the material for informational purposes only. To avoid misunderstanding, you may also want to note that "informational purposes" 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 constructors that they may GE! 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. chat 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 environmentalproblems 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 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 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 thegeotechnical 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.
