Presentation of the data gathered during the investigation, together with our geotechnical related opinions, are included in this report. A. Site Description: At the time of drilling, the site was fairly flat and cleared. B. Project Description: A two-story single family residence is planned to be constructed on the site. Loads from the 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. Some additional site fill may be required to reach the desired grades., FILE C�1JY Ronald G. Keller, P.E.: 37293 / SI Lic. No.: 860 / Julie E.

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 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. D. Site Investigation: The site investigation program consisted of performing three (3) 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 boring logs. 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 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 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 groundwater level are shown on the attached logs. Ronald G. Keller, P.E.: 37293 / SI Lic. No.: 860 / Julie E.

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 and some fine-grained sand that is slightly silty or slightly clayed. Some traces of hardpan were encountered in the borings. "N" values recorded during the boring operation indicate the soil density is generally medium dense to dense. Please refer to the soil boring logs for specific information relative to the soil description. Based on the existing soil conditions, the proposed structure can be supported on a shallow foundation system provided that the site is properly prepared. The following sections provide recommendations for the site preparation and foundation design. F. Site Preparation: After the exposed surface has been proofrolled, the building and pavement areas may be filled to the desired grades. Any 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. Ronald G. Keller, P.E.: 37293 / SI Lic. No.: 860 / Julie E.

Foundation: Provided that our recommendations for site preparation are followed, the proposed structure may be supported on conventional concrete, 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 3/ of an inch and differential settlement of less than % of an inch. The majority of the settlement 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. An estimated modulus of subgrade reaction of 150 pounds per cubic inch (pci) can be used for design of the slab -on -grade. We recommend that expansion or control joints be incorporated in the slab at frequent intervals to control settlement and 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. Ronald G. Keller, P.E.: 37293 / SI Lic.
