Our observations were completed on an on -call, part- time basis between the dates of November 19, 2002 and July 17, 2003. • Site Stripping: Prior to construc the site contained surface vegetation in structural areas. Roadways and lots were stripped of vegetation between November 19 and 25'', 2002. Based on our field observations, the site was stripped of organic topsoil in general accordance with our recommendations. :.• • Subgrado Conditions: After stripping had been completed, the site subgrade soft was cement treated for planned construction activities in the winter.

CGT conducted 6 in- place relative compaction tests on the native brown silt fill. Based on our field observations and in place density testing the native silt fill for roadways was placed and compacted in general accordance with our recommendations (92 percent of ASTM D- 1557). • Roadway Aggregate Base Rock: CGT conducted 12 In -place relative compaction tests on the roadway aggregate base rock on May 2, 2003.
