It is our understanding that the <br /> existing, approximately 376.5 square foot patio and deck were constructed without a <br /> slope stability assessment being preformed. Niels Tygesen with the City of Everett <br /> Planning and Development Services stated that we could address any site slability <br /> issues arising from both the existing construction and proposed deck roof with a brief <br /> letter. <br /> SITE CONDITIONS <br /> This section discusses the general sur(ace and subsurface conditions observed at the <br /> project site at the time of our field investigation. Interpretations of the site conditions are <br /> based on the results of our review of available information, site reconnaissance and our <br /> experience in the project vicinity. <br /> General Geologic Conditions <br /> Geologic information for the project site was obtained from the Washington State <br /> Geologic Iniormation PoRal — Interactive Map, compiled by the Washington State <br /> Department of Natural Resources. According to this map, deposits in this area are <br /> classified as glacial till. These deposits consist of a hard, sandy clay and gravel. Site <br /> soils were relatively consistent with the mapped geology. <br /> Page 1 of 4 � <br />
