In addition, <br /> soil profiles were obtained from four test borings drilled for a geotechnical <br /> investigation performed by our firm. Copies of the test borings are included <br /> with this letter. Reference is made to our geotechnical investigation report <br /> dated June 16, 1987. <br /> The percolation test holes were drilled and set-up on June 10, 1987, by <br /> representatives of our firm. The test holes were drilled to depths of approxi- <br /> mately 36 inches and 4-inch diameter perforated PVC pipe was inserted into the <br /> test holes. The test holes were then filled to the surface with relatively <br /> clean water and left to soak overnight. <br /> On June 11, 1987, a representative of our firm returned to the site to per- <br /> form the percolation tests. The tests were performed according to San Joaquin <br /> County guidelines and the last 30 minutes of each test was observed by a County <br /> Health Sanitarian. The percolation tests were measured to have no drop in water <br /> level for the last 30 minutes. Copies of the county approved test sheets are <br /> attached to this letter. <br /> We trust this letter presents the information requested at this time. If <br /> you have any questions regarding this project, please contact us. <br /> Respectfully submitted, <br /> J. H. KL FELLDEERR & ASSOCIATES <br /> Ron Heinzen, C.
