(Soilogic) personnel have completed the geologic evaluation you requested for the above referenced project. Our evaluation was completed through review of mapped and published information concerning site soil and groundwater conditions. A list of the references reviewed is included with this report. The subject property includes a total of approximately 320 acres located in the West YZ of Section 32, Township 3 North, Range 65 West of the 6th Principal Meridian in Weld County, Colorado to be developed as light industrial/commercial. The property is located southeast of the intersection of Weld County Roads 39 and 28. The site is generally gently sloping to the northeast with the maximum difference in ground surface elevation across the site estimated to be approximately 70 feet. The included soil type delineation diagram outlines those soil groupings identified at the site by Weld County Soil Conservation Service (SCS) maps. SCS descriptions of those soil types are included with this report. In general, the near surface soils at this site appear to consist of low plasticity silty/clayey sands from the Olney, Osgood, Valent and Vona series. The mapped soils consist of older gravels and alluviums from the Pre-Bull Lake Age geologic period. Mapped information indicates the property is not in an area identified as being flood prone and would be expected to have groundwater at depths ranging from approximately 5 to 20 below ground surface. Longer term observation of site groundwater levels in wells which are cased and sealed from the influence of surface water would be required to better define seasonal high groundwater levels and possible fluctuations in those levels over time. Soilogic, Inc. 4350 Highway 66• Longmont,CO 80504•(970)674-3430 P.O. Box 1121 •Hayden,CO 81639• (970)276-2087 Geology Report JL Butterball Property Weld County,Colorado Soilogic# 12-1039 2 According to geologic maps of the area, the site overburden soils are underlain by the Laramie bedrock formation consisting of shale, claystone and sandstone from the upper cretaceous period. According to SCS data, the depth to bedrock would be expected to be greater than 5 feet across the site. Based on our review of the site as outlined above, we expect the near surface soils could be used for support of lightly to moderately loaded commercial/industrial structures. Deep foundation systems could be employed if heavy foundation loads are anticipated. The site soils would be expected to exhibit percolation rates supporting conventional septic system construction. Site specific percolation testing would be required to better evaluate the percolation rate of near surface soils and depth to bedrock and groundwater in septic absorption field areas. Engineered septic systems would be required for industrial treatment applications. During our review of available site data, we did not identify other potential geologic hazards as outlined in H.B. 1041. In addition, we did not identify economically recoverable gravel resources at this site. We appreciate the opportunity to be of service to you on this project. If we can be of further service to you in any way or if you have any questions concerning the enclosed information,please do not hesitate to contact us.

April 13, 2012 AGPRofessionals, LLC 4350 Highway 66 Longmont, Colorado 80504 Attn: Mr. Tim Naylor Re: Geology Report JL Butterball Property (W%:of Section 32, T3N, R65W) Weld County, Colorado Soilogic Project# 12-1037 Mr.Naylor: Soilogic, Inc. (Soilogic) personnel have completed the geologic evaluation you requested for the above referenced project. Our evaluation was completed through review of mapped and published information concerning site soil and groundwater conditions. A list of the references reviewed is included with this report. The subject property includes a total of approximately 320 acres located in the West 1/2 of Section 32, Township 3 North, Range 65 West of the 6th Principal Meridian in Weld County, Colorado to be developed as light industrialcommercial. The property is located southeast of the intersection of Weld County Roads 39 and 28. The site is generally gently sloping to the northeast with the maximum difference in ground surface elevation across the site estimated to be approximately 70 feet. The included soil type delineation diagram outlines those soil groupings identified at the site by Weld County Soil Conservation Service (SCS) maps. SCS descriptions of those soil types are included with this report. In general, the near surface soils at this site appear to consist of low plasticity silty/clayey sands from the Olney, Osgood, Valent and Vona series. The mapped soils consist of older gravels and alluviums from the Pre-Bull Lake Age geologic period. Mapped information indicates the property is not in an area identified as being flood prone and would be expected to have groundwater at depths ranging from approximately 5 to 20 below ground surface. Longer term observation of site groundwater levels in wells which are cased and sealed from the influence of surface water would be required to better define seasonal high groundwater levels and possible fluctuations in those levels over time. Soilogic, Inc. 4350 Highway 66 • Longmont,CO 80504•(970)674-3430 P.O. Box 1121 • Hayden,CO 81639 • (970)276-2087 Geology Report JL Butterball Property Weld County, Colorado Soilogic# 12-1039 2 According to geologic maps of the area, the site overburden soils are underlain by the Laramie bedrock formation consisting of shale, claystone and sandstone from the upper cretaceous period. According to SCS data, the depth to bedrock would be expected to be greater than 5 feet across the site. Based on our review of the site as outlined above, we expect the near surface soils could be used for support of lightly to moderately loaded commercial/industrial structures. Deep foundation systems could be employed if heavy foundation loads are anticipated. The site soils would be expected to exhibit percolation rates supporting conventional septic system construction. Site specific percolation testing would be required to better evaluate the percolation rate of near surface soils and depth to bedrock and groundwater in septic absorption field areas. Engineered septic systems would be required for industrial treatment applications. During our review of available site data, we did not identify other potential geologic hazards as outlined in H.B. 1041. In addition, we did not identify economically recoverable gravel resources at this site. We appreciate the opportunity to be of service to you on this project.
