Presentation of the data gathered during the investigation, together with our geotechnical related opinions, are included in this report. Site Description: At the time of drilling, the 30± acre site had a 12± acre pond and was found to be fairly flat. Generally, the site had dense underbrush and was heavily wooded with oak and pepper trees. However, the areas of proposed construction were cleared. The corners of the single- family residence and the mother-in-law suite were staked prior to our arrival. Project Description: A partial two-story, single-family residence and a detached mother-in-law suite are planned to be constructed on the site. As the mother -in -law -suite is planned to be constructed at a later date, the parameters for the mother-in-law suite are unknown at the time of this report. Loads from the structures will be transferred to the ground by conventional shallow footings. For our analysis, we estimate the maximum loads will be less than 3,000 pounds per linear foot along the wall foundation of the single-family residence. Due to the current site conditions, some additional site fill may be required to reach the desired grades. Page 1 of 4 In #tp\ 2115 Keen Road IV ENGINEERING Fort Pierce, Florida A%OWL AND TESTING KSM Project#: 213468-b The scope of our study consisted of the following: Performed Standard Penetration Test borings in the proposed construction area to estimate the subsoil relative density. 2. Measured the observed groundwater level at each boring. 3. Evaluated the existing soil conditions with respect to the proposed construction and provided recommendations for site preparation and foundation design. 4. Prepared this report to document our findings. Site Investigation: The site investigation program consisted of performing four (4) Standard Penetration Test (SPT) borings, in the proposed single-family residence, and one (1) SPT boring in the location of the proposed mother-in-law suite. The SPT borings were terminated at depths of approximately 10 to 14 feet below grade and their locations are indicated on the attached location plan. The SPT borings were completed in accordance with procedures described in ASTM D-1586. A standard 1.5 inch I.D., 2 inch O.D. split -spoon sampler is driven into the soil by successive blows of a 140 pound hammer freely failing 30 inches. The number of blows required to drive the sampler 1 foot, after seating 6 in., is designated the Penetration Resistance, or "N" value. At regular intervals the sampler is extracted from the ground and opened to allow visual examination and classification of the retained soil sample. Also, the groundwater table was allowed to stabilize and the depth of the groundwater elevation recorded from existing grade. The records of the soils encountered, the penetration resistances and observed groundwater level are shown on the attached logs. Engineering Evaluation and Conclusions: Based on the information obtained from this site investigation, we are pleased to offer the following evaluation: The boring logs indicate the subsurface soils consist mostly of fine-grained sand, fine-grained clayed sand, and slightly silty fine-grained sand. "N" values recorded during the boring operation indicate the soil density is generally firm at the surface and becomes medium dense below. Please refer to the soil boring logs for specific information relative to the soil description. Based on the existing soil conditions, the proposed single-family residence can be supported on a shallow foundation system provided that the site is properly prepared. Page 2 of 4 2115 Keen Road Fort Pierce, Florida KSM Project #: 213468-b UP OIL 9 ENGINEERING X%IJJJV1 AND TESTING Provided that the existing site conditions in the area of the mother-in-law suite are not altered between the time of issuing of this report and the beginning of construction, it is our professional opinion that the subsurface soils in this location is suitable to support the proposed mother-in-law suite. Please note that the recommendations listed in this report are subject to change once the parameters of the mother-in-law suite are known. Please contact our office once this information becomes available. The following sections provide recommendations for the site preparation and foundation design. Typical Site Preparation. - The proposed building areas and areas to be paved, plus a minimum margin of five feet beyond the proposed construction shall be stripped and grubbed of surface debris, including vegetation, roots and organic matter. Stumps shall be removed entirely. The building areas should be graded level and proofrolled. Any soft yielding areas shall be excavated and replaced with clean compacted fill. Sufficient passes should be made during compaction operations to produce a density no less than 95 percent of its modified dry Proctor value (ASTM D 1557) to a depth of two feet. After the exposed surface has been proofrolled, the building and pavement areas may be filled to the desired grades. The fill material shall consist of clean granular sand containing less than 10% material passing the U.S. Standard No. 200 mesh sieve. Place structural fill in loose layers of 12 inches in thickness and compact each lift to at least 95 percent of its modified dry Proctor value. After excavating for the footings, the disturbed footing subgrade should be recompacted to 95 percent (minimum) of its modified dry Proctor value. This can be best achieved by making several passes with a relatively light -weight walk -behind vibratory sled or roller. Foundation for the Two -Story Residence: Provided that our recommendations for site preparation are followed, the proposed structure may be supported on a conventional concrete monolithic foundation, with steel reinforced footings designed for an allowable soil bearing pressure of 2,500 pounds per square foot, or less. With the foundation properly designed and the site properly prepared, we anticipate total settlements less than % of an inch and differential settlement of less than % of an inch. The majority of the settlement should occur during construction. This is based on the assumed loading as shown on the front page of this report and a minimum continuous stemwall footer width of 18 inches with a minimum embedment of 16 inches. If the loading or footer is to vary from these parameters, please contact our office for additional settlement calculations.

Floor Slabs: A conventional slab -on -grade can be used in the "at grade" portion of the buildings. We recommend the disturbed subgrade below the floor slab be re -compacted to 95 percent of the modified Proctor maximum dry density (ASTM D 1557) prior to placement of the concrete. We recommend that control joints be incorporated in the slab at frequent intervals to control shrinkage cracks. A moisture barrier is recommended beneath the floor slab to prevent moisture migration from the underlying soil resulting in dampness of the slab. Closure: Based upon our subsurface investigation at the above -mentioned project location, the reliance of the recommendations presented within this signed and sealed report is predicated on KSM representative's involvement to verify that not only have the soils been prepared following the indicated recommendations, but the foundations are installed in compliance within the parameters indicated. The Structural Engineer of Record is responsible for confirming that the estimated capacities provided are adequate for the anticipated loading. If additional capacity is required, KSM is to be notified so that our recommendations can be amended as required. This report has been prepared in accordance with generally accepted soil and foundation engineering practices based on the results of the test borings and the assumed loading conditions. No warranties, either expressed or implied, are intended or made. This report does not reflect any variations which may occur between the borings. If variations appear evident during the course of construction, it would be necessary to re-evaluate the recommendations of this project. Environmental conditions, wetland delineation, water quality, and municipal requirements are not a part of this report. We are pleased to be of assistance to you on this phase of your project.
