Our most recent <br />tests were conducted on July llth and 12th, 1977, at locations <br />indicated on the attached sketch. <br />INVESTIGATION METHODS: <br />Percolation -tests were conducted in the same manner as <br />described to you in our previc •eports of May of this <br />year. <br />RESULTS: <br />Percolation tests indicated soil absorptivities in minutes <br />per inch (mpi), as follows: <br />Surface <br />Test N Elevation <br />P-9 969 <br />P-10 968. <br />P-7 971 <br />P-8 970 <br />Soil At Rate <br />Test Depth (m i <br />Silty Clayey Sand (SM-SC) 25 <br />Silty Clayey Sand (SM-SC) 30 <br />SILTY CLAYEY SAND (SM-SC) 15 <br />SILTY CLAYEY SAND (SM-SC) 10 <br />CONSULTING ENGINEERS/SOILS AND MATERIALS <br />Test Borings • Foundation Engtns long and Reen—ondations • btspecUon of Construction • Material Testing of Sods Concrete and budding Components <br />
