Presenta ion of the data gathered during the investigation, together with our geotechnical related pinions, are included in this report. A. Site Description: At the time of drilling, the rivbr front site was fairly flat with a few trees and light surface vegetation. B. Project Description: A single family residence i planned to be constructed on the site. Loads from the one- story structure will be transferred to the ground by conventional shallow footings. We estimate the maximum loads will be less than 2,500 pounds per linear foot along the wall foundation -and less than 15 kips for any individual column loads. We estimate that several feet of site fill will be required to reach the desired grades. File C®py.� Ronald G. Keller, P.E.: 37293 / SI Lic. No.: 860 / Julie E.

Performed Standard Penetration Test Borings in the proposed construction area to estimate the subsoil relative density. 2. Measured the groundwater level at each boring. 3. Evaluated the existing i'oil conditions with respect to the proposed construction and provided recommendations for site preparation and foundation design. 4. Prepared this report to document our findings. D. Site Investigation: The site investigation progra I consisted of performing four (4) Standard Penetration Test borings (SPT), in the proposed construction area. The SPT borings were terminated at depths of 10 to 14 feet below grade. The locations of the borings are indicated on the. attached bopng Location Plan. p The SPT borings were completed in accordance with procedures described in ASTM D- 1586. A standard 1.5 inch I. ., 2 inch O.D. split -spoon sampler is driven into the soil by successive blows of a 140 1pound hammer freely falling 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 �dwater llow visual examination and classification of the retained soil sample. Also, the grou 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 groundwater level are shown on the attached logs. Ronald G. Keller, P.E.: 37293 / SI Lic. No.: 860 / Julie E.

LUCIE (772) 229-9093 FAX (772) 589-6469 -3- Conclusions: June 19, 2017 from this site investigation, we are pleased to offer The boring logs indicate the s bsurface soils consist mostly of fine-grained sand and some fine-grained sand that is slightly clayed. "N" values recorded during the boring operation indicate the soil den T"formation ty is generally loose to medium dense. Please refer to the soil boring logs for specificrelative to the soil description. Based on the existing soil co ditions, the proposed structure can be supported on a shallow foundation system provided that the site is properly prepared. The following sections provide design. F. Site Preparation: The proposed building area beyond the proposed cons - including vegetation, roots a building area should be grai excavated and replaced wit during' compaction operatio modified dry Proctor value (f mendations for the site preparation and foundation id areas to be paved, plus a minimum margin of five feet Iction shall be stripped and grubbed of surface debris, i organic matter. Stumps shall be removed entirely. The id level and proofrolled. Any soft yielding areas shall be clean compacted fill. Sufficient passes should be made > to produce a density no less than 95 percent of its ;TM 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 Ilayers 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 passe with a relatively light -weight walk -behind vibratory sled or roller. Ronald G. Keller, P.E.: 37293 / SI Lic. No.: 860 / Julie E.

Foundation: Provided that our recommendItions for site preparation are followed, the proposed structure may be supported on onventional concrete steel reinforced footings designed for an allowable soil bearing pre�sure of 2,000 pounds per square foot, or less. With the foundation properly qlesigned and the site properly prepared, we anticipate total settlements less than 3/ of an inch and differential settlement of less than % of an inch. The majority of the settleljnent should occur during construction. H. Floor Slabs: A conventional _slab -on -grade can be used in the "at grade" portion of the residence. 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. �n estimated modulus of subgrade reaction of 150 pounds per cubic inch (pci) can be u ed for design of the stab -on -grade. We recommend that control joints be incorporate ld in the slab at frequent intervals to control shrinkage cracks. A moisture barrier is recomr�'ended beneath the floor slab to prevent moisture migration from the underlying soil resulting in dampness of the slab. I. Swimming Pool: Based on the existing soil conditions, the proposed pool can be designed and constructed using an allowable soil bearing pressure of 2,000 pounds per square foot. When excavating the pool, if any organic soil or soft material is encountered, these materials/soils should be I removed and replaced with W stones so the subgrade becomes firm below the r)of bottom. Backfill material behind the pool shell shall consist of clean granular sand with less than 10 percent "fines" passing the U.S. No. 200 sieve. Place backfill material in loose lifts of 12 inches in thickness and compact each lift to no less than 95 percent of its modified dry Proctor value (ASTM D 1557). Ronald G.
