Boring No. Sample Depth Classification • <br /> 2 3' -8' SAND, fine grained, grayish <br /> brown, waterbearing (SP-SM) <br /> Based on the samples submitted to us, the organic soils consist of an organic <br /> clayey sand. The underlying sand is fine grained with a SP-SM symbol indica- <br /> ting there is from 5% to 12% passing a #200 sieve. <br /> In our opinion, the organic soils are weak, compressible and highly frost <br /> susceptible. In our opinion, these soils should be completely removed from <br /> the area of the proposed tennis court. We also recommend a minimum 5' over- <br /> size beyond the edge of the tennis court. After the unsuitable soils have <br /> been removed, we recommend placing a controlled compacted granular fill <br /> to subgrade elevation. Because of the high water level , we recommend that <br /> the fill be a non-frost susceptible sand fill . We recommend that the soil <br /> have less than 50% passing a #40 sieve and less than 5% passing a #200 sieve. <br /> We recommend compacting this fill to a minimum of 98% of standard Proctor <br /> density (ASTM: D 698-78) . This type of fill material should greatly minimize <br /> potential damage due to frost heaving. Also it should be possible to compact <br /> this type of fill material with the relatively high ground water level condi- <br /> tion. <br /> The recommendations contained in this report represent our professional <br /> opinions. These opinions were arrived at in accordance with currently accept- <br /> ed engineering practices at this time and location.
