The near surface site lean clay or properly placed and compacted fill and backfill could also be used for direct support of exterior flatwork and site pavements. Other opinions and recommendations concerning design criteria and construction details for the proposed site improvements --- are included with this report.

Principal Engineer F SoILOGIC September 1, 2010 Brinkman Construction, Inc. 3003 East Harmony Road, Suite 300 Fort Collins, Colorado 80528 Attn: Mr. Dave Derbes Re: Geotechnical Subsurface Exploration Report 712 West Laurel Street Fort Collins, Colorado Soilogic Project # 10-1012 Mr. Derbes: Soilogic, Inc. (Soilogic) personnel have completed the geotechnical subsurface exploration you requested for the proposed duplexes to be constructed at 712 West Laurel Street in Fort Collins, Colorado. The results of our subsurface exploration and pertinent geotechnical engineering recommendations are included with this report. In summary, the subsurface materials encountered in the completed site borings consisted of a thin layer of topsoil and vegetation underlain by light brown to light reddish brown - lean clay with varying amounts of silt and sand. The lean clay showed low volume change potential with variation in moisture content at in situ moisture and density _. conditions. The lean clay extended to the bottom of boring B-3 at a depth of approximately 10 feet below ground surface and to depths ranging from approximately 12 to 13%2 feet below ground surface at boring locations B-1 and B-2. At boring locations B-1 and B-2, the lean clay was underlain by clayey sand and gravel. The sand and gravel was dense and extended to the bottom of boring at a depth of approximately 15 feet below present site grads. Groundwater was not encountered in any of the completed site borings at the time of drilling. Based on the subsurface conditions encountered, results of laboratory testing and type of _. construction proposed, it is our opinion the proposed buildings could be constructed with conventional footing foundations and floor slabs bearing on natural undisturbed lean clay with low swell potential and/or properly placed and compacted fill and backfill. Careful evaluation of the proposed foundation bearing materials should be completed at the time Soilogic, Inc. 1435 Hilltop Circle • Windsor, CO 80550 • (970) 674-3430 P.O.
