ALASKA 99503 o 277-O251 June 3, 1975 P B & J, Company 3204 Lois Drive Anchorage, Alaska Re: Sub~ 99503 Investi( ~ion on Gentlemen: As per your request, our Company performed a soils investigation on this Project. A total of 5 test holes were drilled to a minimum depth of 15 feet with a Mobile B-50 Drill mounted on a tracked Nodwell. The soils were visually classified in the field by Jim Mack of our Company. The location and the results of the test borings are enclosed in this report. In general, the soils encountered on this property consist of coarse gravels and sands. The silt content varies from less than 5 percent to more than 15 percent. The ground water levels were between minus eleven and twelve feet below the existing ground surface throughout the subdivision. The type of soils encountered in this subdivision are usable for on-site sewage systems. If you have any questions of if we can be of further assistance on the above project, please contact our office. Very truly yours, JDM/dt CONSTRUCTION TEST LAB James D.
