Enclosed, please find <br /> a copy of our soil log report showing the lot layout of approx- <br /> imate hole locations. <br /> During our soil investigation, we found that the lot contained <br /> very shallow clayloam sub soil with an underlying, heavily <br /> compacted clay soil below; the depth ran 6 feet, plus. This <br /> is a stable type of clay, in that it is not stratified with sand <br /> or silt layers, which could cause possible slipping. It is <br /> our recommendation that upon installation of any foo�ing or <br /> structural building walls, that these all be placed on firm <br /> � original soil and are not to be placed on any compacted clay <br /> fill material. As long as the footings are installed directly <br /> on top of the firm original clay base, we don 't see where there <br /> should be any major structural problems . <br /> It would also be our recommendation to prevent any water build- <br /> up on the lot, to take all footing drains and down spout drains <br /> down around the east or west side o£ the house, tiglitlining <br /> thPm back down into the bottom swale to the north and day- <br /> lighting out any water, ther.eby, helping to prevent any <br /> hydraulic pressure which could cause, or give you pr.oblems <br /> at a later date. These could all be interg :ated with your <br /> footing and down spout drain system, and th refore, carried out <br /> again through tightlines down, back and dayiighting into the <br /> already existing swale to the north. <br /> We trust that this report will be of help to �ou in obt•aininq <br /> the necessary building permits on Lot 12 . If� you have any <br /> further questions concerning the soil data, pl ,:ase don ' t <br /> hesitate to call. [9e thank you for your busincss and hope <br /> that we might be of further help to you in the �uturn. <br /> Sincerely, <br /> D��noug��. <br /> Encl. <br /> DB/es <br /> I f'CItCOI Afl�lnl Tr-tilinir: cn�i nnini vc-�� � � ..����,�, . .•. .... .._.__ <br />
