GEOTECHNICAL ENGINEERING STUDY Proposed Single-Family Residence Lot 1, 4931 Glenwood Avenue Everett, Washington This report presents the findings and recommendations of our geotechnical engineering study for the site of a proposed single-family house to be constructed in Everett, Washingtcn. The Vicinity Map, Plate 1, illustrates the general location of the site. We were provided with site plans and a topographic map. Kutev Design developed these plans, which are dated June 2000. Based on these pians, we anticipate that the existing parcel will be sub-divided into three separate lots and that you will be constructing a house on Lot 1. The proposed single-family residence on the southernmost lot will be constructed partially with a slab on grade and partially witli a crawl space. The elevations of the slabs for the garage and the house are approximately 222 feet and 225 feet, respectfully. Th� two-story str�cture will be 22 feet in height with an approximate 7-foot-high roof for a total building height of 29 feet. The proposed residence will have an attached tv.�o-stall garage. The footprint of the building is proposed to have a minimum setback along the northern property boundary once the lot is short-platted. Also, the eastern portion of the house will be near the eastern property boundary with access from the existinq driveway. The building is to be set back from the crest of the slope, and back from the top of the rockery approximately 30 feet. S/TE CONDITIONS SURFACE Lot 1 is irregular in shape and is traversed by a driveway that serves the existing house on Lot 3. This driveway is on the south and west sides of the subject lot. An 8- to 10-foot-high rockery constructed approximately one year ago is on the upslope side of the driveway on the west portion of the subject lot, as this driveway traverses a slope. The house site is relatively level, but there is a moderate slope immediately to the west of the building site. The property except near the existing residence and yard area is overgrown with vegetation and large trees. The vegetation is primarily blackberry bushes and smaller shrubs covering the slope. An old septic system is noted to exist south of the existing residence. The septic system is within the footprint of the proposed building. The drain field of the system is to the south of the septic tank. This system is no longer used, as the residence is now connected to city water and sewer. These utilities parallel the driveway and access vdith Glenwood Avenue. :UBSURFACE T.�e subsurface conditions were explored by excavating t�vo test pits at the approximate tocations shown on the Site Exploration Plan, Plate 2.
