Lateral Pressure The influence of loads imposed by adjacent footings should be added to the lateral loads imposed by the soil. The stress distribution beneath a footing can be approximately represented by two imaginary lines sloping down and outward from the base of footings at an angle of 1 hori- zontal to 2 vertical (1:2) as shown on Plate 2. B. Soil Absorption System Based upon the results of the two percolation tests, we recommend a design percolation rate of lO minutes per inch be used for the sandy gravel (GP-GM) soil. The top of the absorption system should be a mini- mum of four feet below ground surface and the bottom should be in the sandy gravel (GP-GM) soils. If these percolation rates are not satisfac- tory for final design or if the locations of the absorption system changes from the area we explored, we should perform additional percola- tion tests. C. Heavy Traffic Pavement Design In areas to receive bus or tractor-trailer traffic, the pavement section should consist of a minimum of 2 inches of asphalt concrete over- lying a minimum of 4 inches of non-frost susceptible(*) crushed aggre- gate base course, and a minimum of 10 inches of NFS well-graded (*) Non-frost susceptible (NFS) material is sand or gravel that contains no more than three percent particles by weight smaller than the 0.02 mm size. - 13- 3~0 ~ ~ 360 370 340 ~ Laboratory Tests ~wm_ = u .~oo = o -#200=12.3% 3.7 ~ ~?-OG OF BORING 7* Equipment~" O.D.

Such testing has been conducted with the groundwater level existing at least twenty-three (23) feet below the ground surface. Please see attached material for details. Very truly yours, Roberta k.

D,t~: October 25, 1983 suHect: Ship Creek Water Treatment Plant JobNo.: 15014,005.08 On Friday, October 21, 1983, we redrilled Boring 7 at the subject site to a depth of 23 feet with a truck-mounted Mobile Drill B-61 rig using 3-3/8" inside diameter (I.D.) hollow-stem augers. Upon completion of the drilling, we installed two-inch I.D. PVC pipe, slotted the bottom 15 feet down the inside of the hollow auger stem and withdrew the auger. The PVC was capped on the bottom and a pressure release vent was cut in the top under the top cap to allow air to escape should ground water seep into the pipe. The annular space was backfilled with cuttings from the dril- ling' and mounded to divert surface runoff away from tile pipe. cc: East 5~lh Place Telephone Alaska Hawaii Texas AK 99502 907/563- 8102 California Nevada Washington Telex 340523 URS MEMORANDUM .............................. October 31, 1983 To: Ship Creek WTP Expansion From: Roberta Piper, P.E. · Civil Engineer RE: 7-day groundwater test at boring #7 Files On October 21, 1983, Harding Lawson, geotechnical consultants, prepared boring hole #7 for a 7-day groundwater test (see attached letter from Randy Ross of Harding Lawson regarding their work). The boring was undisturbed until October 29, 1983, when it was checked for groundwater level. The test was conducted as follows: 1. Removal of protective cap at top of casing. 2. A length of cotton twine, marked in one foot intervals, weighted at the free end and the weight wrapped in absorbent material, was lowered gradually down casing. 3. As line was lowered care was taken to listen for when weight made contact with water. 4. When weight made definite contact wit'h bottom of boring, length of line was checked against known boring depth to check for weight hitting obstruction other than bottom of boring. Line and covered weight removed careful]'y and in- spected. Absorbent material covering weight was not wet nor was the cotton twine. 6. Cap on casing replaced. From this test it is concluded that the groundwater level exists greater than twenty-three (23) feet below the ground surface at boring 7. cc: R. Robinson, DHEP¥$ .....
