lr I 1 <br />Boring No. Sample Depth Classification L <br />2 3'-8' SAND, fine grained, rayish <br />brown, waterbearing �SP-$M) <br />ri <br />'t <br />cf; <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 here is from J% to 12% passing a :200 sieve. <br />- - - 1`, <br />�4t1 <br />Jr, 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 />t <br />:. been removed, we recommend placing a controlled compacted granular fill <br />14 <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 140 sieve and less than 5% passing a 92001tieve. <br />We recommend compacting this .fill to a minimum of 98% of standard Proctor <br />density (ASTM: 0 698-78). This type of fist material should greatly minimite <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 />�iThe recommendations contained, in this report represent our professional <br />opinions. These opinions were arrived at in accordance with currently accept- <br />o ed engineering practices at this time and location.
