1. Figure 1 Approximate Project Site Location At the time of the subsurface exploration the project site was fairly level with an estimated grade differential on the order of 1 to 2 feet across the proposed project area Structural loads were not provided however we assumed that the proposed building will be lightly loaded with maximum column loads and bearing wall loads in the range of 20 to 40 kips and 2 to 3 kips per linear foot klf respectively Proposed grading plans were not provided to us at the time of preparing this proposal however for the purpose of this proposal we assumed that maximum cut and fill depths of less than 2 feet will be required to achieve design grades within the proposed building area 2 0 SCOPE OF SERVICES The purpose of the geotechnical exploration was to determine general subsurface conditions at specific boring locations and to gather data on which to base a geotechnical evaluation with respect to the proposed construction The information gathered from the exploration was evaluated to determine suitable foundation alternatives for the proposed building The information was also evaluated to help determine if any special building pad preparation procedures will be required during the earthwork phase of the project The work included soil test borings laboratory analysis and geotechnical evaluation appropriate to address the geotechnical aspects of the proposed construction The results of our exploration

7. a qualified representative should observe the proofrolling operations Considering that the onsite materials encountered in the borings are mostly comprised of fine grained silty clayey sand and depending on the moisture contents at the time of construction proofrolling may reduce the stability of the subgrade soils If this occurs the general procedures should be modified such as deleting or reducing the proofrolling or stabilizing the soils Any soft very loose unstable or otherwise unsuitable soils identified during the proofrolling or subgrade evaluation process should be moisture conditioned undercut to suitable material or stabilized in place prior to fill placement or new construction Information regarding suitable stabilization methods can be provided during construction based on actual conditions encountered 7 4 STRUCTURAL FILL We recommend that the structural fill at the site be composed of material with a maximum dry density in excess of 100 pounds per cubic foot pef Plasticity Index PI less than 20 and Liquid Limit LL less than 45 All structural fill materials should be free of any organics should not contain rock fragments greater than 3 inches in any dimension and should be properly moisture conditioned prior to placement Any fill to be placed at the site should be approved by the geotechnical engineer Based upon the soils encountered in the borings the onsite materials appear suitable for use as structur

ORATION The authorized subsurface exploration was performed on May 20 and 21 2013 The subsurface exploration presented in this report consisted of two 2 soil test borings drilled within the proposed building area Borings B l and B 2 were drilled to a depth of approximately 14 5 feet below existing ground surface within the proposed building area on the east and west ends respectively The soil boring locations were determined in the field by a representative of City of Stillwater The approximate boring locations are indicated on the Boring Location Plan included in the Appendix of this report The borings were drilled with by Data Testing with a truck mounted drill rig equipped with solid stem augers and automatic hammer At each boring location soil samples were retrieved at standard sampling intervals by driving a split tube sampler The borehole was first advanced to the sample depth by augering and the sampling tools were placed in the open hole The sampler was then driven into the ground 18 inches by blows from a 140 pound hammer falling 30 inches The number of blows required to drive the sampler each 6 inch increment was recorded The initial increment is considered the seating blows where the sampler penetrates any loose or disturbed soil in the bottom of the borehole The blows required to penetrate the final two increments are added together and referred to as the Standard Penetration Test SPT N Value The N Value whe
