(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 wasgrellirinary<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 e 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. 1. 820 Brevard Avenule'i Rockledge, Florida 32955' (321) 638-0808 Fax (321)1638-0978 www.UniversalEngineering.com a Oakland Lake Estates Subdivision Universal Project No. 0330.1700052.0000 Fort Pierce, Saint Lucie County, Florida Preliminary Subsurface Exploration rd 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.

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 ofthis report bythem 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 mestimating. 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 ghat 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 Iodate '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. r 3 820 Brevard venue, Rockledge, Florida 32955 (321) 638-0808 Faxs1(321) 638-0978 ( www.U.nivbrsa[Engineering.coni Oakland Lake Estates, Subdivision Universal Project No. 0336.1700052.0000 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 137 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=BarrellSampling 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 wet,e,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 PARTICLESIZE 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. 4 820 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 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 sampleswere 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,)n the following Table II. For more detailed soil profiles, please refer to the attached boring logs.

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 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: aMeasured groundwater level b Drainage characteristics of existing soil types C. Season of the year (wet/dry season) 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 6 820 '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 h,,, On -site types of vegetation i. Area'topography (ground surface elevations) n 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,normai levels for the month of April. Year -tog rainfall for 2017 through May 8th was";approximately 6%2 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 2Y2 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. i 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 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 conventional_one;to two ston%`resitlential construction} 7 } 8�0 Brevard Avenue, Rockledge, Florida 32955 (321) 63a -0808 Fax (321) 638-0978 www.Universa[Engineering.com, Oakland Lake Estates Subdivision Universal Project No. 0330.1700052.0000 Fort.

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 exposes geotechnical,engineers to a wide array of risk -confrontation techniques that can be.of genuine benefit for everyone involved,with a i' 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 solely for the client. Those who rely on a geotechnical-engineering report prepared for a di rent client can be seriously misled. No one except authorized client representatives should rely on this geotechnical-engineering report without first 1 conferring with the geotechnical engineer who prepared it. And no one - not even you,- should apply this report for any purpose or project'except the one originally contemplated. Read this Report In Full Costly problems have occurred because those relying on a geotechnical- -engineering report did not read it in its entirety. Do not rely on an I 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 reporbconveys. 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, configuration, and performance criteria; . the structure's 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 site's size or shape; • the function of the proposed structure, as when its 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 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. 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 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. , Most of. the "Findings" Related ,in This Report Are Professional _ Opinions 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 Aerived 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-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 startfto project finish, so the individual can provide informed guidance quickly, whene7 needed. 11 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 fenal, 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 assumed 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 if you fail 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. You should also confront the risk of constructors misinterpreting this report. Do so by retaining your geotechnical engineer to participate in prebid and preconstruction conferences and to perform construction observation. 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 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.
