The fuil report with engineering specifications for house construction is <br /> forthcoming. Allied drilled two borings on this lot within the anticipated area fo�new house construction. <br /> Boring 1 was driiled near the front of the house_ Bonng 2 was drilied near the rear thereof. Ground <br /> conditions at the borings are cltaracterized in the attached Boring Logs. The Boring Logs reveai two <br /> fundamental ground characters. <br /> THE FIRST CHARACTER is that supraglaciai till was predominantly encountered in the borings to their <br /> bottom depths.The till appears to have both oxid�ed and unoxidized zones. The oxidized zone extends <br /> to depths near 13 feet If is lighter coiored by precipitation of oxides on soil grains. These oxides give <br /> this soif its mottling, brownish and lighler colors. The oxidized zone is not related to a persistent ground <br /> water condition_ The uno�adized zone underlies the oxidiaed zone, and it extends from depths near 13 <br /> feet to the bvttom of the borings. It has dark gray color by lack of oxide precipitation on soil grains. This <br /> lack is associated to a persistent ground water condition related to dilution of o�cygen in ground water. <br /> A large natural wetland lies a few blocks northeast of the lot, and �ts water surFace appears to be neariy <br /> 20 feet lower than the lot. This surface is a manifestation of the ground water level in this area. A <br /> smaller natural wetland lies nearty one-half mile northwest of the lot, and it appears to be on the order <br /> of 20 feet (ower than this Iot. The water surface of fhis smaller wetland is an indicator of the ground <br /> water level in this area. eased on water levels of these weUands and dark gray unmottled sflil <br /> encountered in the barings near a depth of 13 feet, the persistent ground water leve! across the lot is <br /> near 13 feet. <br /> WATERPROOFING The Federal Housing Administration (FHA) sets housing consVuction standards <br /> that can guide construction of residential buildings. Based on these standards, we recommend placing <br /> the iowest building floor at least 4 feet above the maximum anticipated ground water level (a persistent <br />
