The site is <br /> situated on the mid-slope of a steep, easterly-declining hillside. The site is currently <br /> vacant and undeveloped. It is covered by over-grown brush on the moderately sloped <br /> west half and dotted by shrubs and mature trees on the steep sloped east half <br /> GEOLOGIC SETTING <br /> The Preliminary Surficial Geologic Map of the Everett 7.5-Minute Quadrangle, <br /> Snohomish County, Washington, by James P. Minard, published by U. S. Geological <br /> Survey in 1985, is referenced for the geologic and soil conditions of the project site. <br /> According to this publication, the surficial soil unit at and in the vicinity of the subject <br /> property is mapped as advance outwash (Qva) deposits, underlain by transitional beds <br /> ((lb) deposits. The transitional beds soil unit is mapped at some distance beyond the <br /> project site to the east. <br /> The geology of the Puget Sound Lowland has been modified by the advance and retreat of <br /> several glaciers in the past one million years or so and the subsequent deposits and <br /> erosions. The latest glacier advanced to the Puget Sound Lowland is referred to as the <br /> Vashon Stade of the Fraser Glaciation which had occurred during the later stages of the <br /> Pleistocene Epoch, and retreated from the region some 12,500 years ago. <br /> The deposits of the advance outwash soil unit are composed of stratified sand and gravel <br /> with very minor amount of silt and clay, deposited by meltwater of advancing glacier of <br /> LIU & ASSOCIATES, INC. <br />
