� <br /> � CqSCApE GEOTECHNICAL INC. <br /> August 6, 1992 Job No. 9207-0SG <br /> ^ Langus proposes W build only on the plateau area. The project site is illustrated in Appendiz <br /> A. <br /> _ The profile of the lot, looking east to west, is defined by three slopes with definitive slope <br /> breaks. East of the cul-de-sac, the first 38 feet are gently sloped downwards at 5 degrees, the <br /> _ ne�t 45 feet are steeply sloped downwazd at nearly 45 degrees, with the last 20 feet sloped <br /> gc;ntly to the basin. Topographic relief is on the order of 30 fcet <br /> The plateau is covered by lush, well manicured lawn grass, free of trees and shrubs. No erosion <br /> — features were noticed, undoubtedly due to the thick and consistent grass vegetating the surface, <br /> - as well as the mild 5 degree slope. <br /> — The steep slope is thickly vegetated by ground cover and uees. Forcst duff, rotting organics, <br /> ' - occupies appmximately 10 inches of the immediate surface. The ground cover wnsists mostly <br /> J of wild blackberry bushes and ferns; the trees, deciduous alders and evergreens. On the surface <br /> -- of the steep slope, an evergreen tree was pistol butted at the base, possibly indicating creep of <br /> the slope. The slope surface is dry, and only minor, isolated erosion features were observed. <br /> - The marshy basin area is covered by thick ground vegetation, with exposed areas of dazk, I <br /> ' organic soils. 1'he basin soils are soft and saturated, with some areas of shallow standing water. :� <br /> Springs seeping from the tce of the steep slope were observed at the south western corner of the ' <br /> lot. <br /> SUBSURFAi;E CONDIT[ONS <br /> cnil C nditions <br /> The site subsurface condi6ons are described below; their corresponding interpretive logs are <br /> 2 <br />
