CEOTECHNICAL ENGINEFRING STUDY Proposed North Point Apartments East Marine View Drive Everett, Washinc�ton This report presenls the findings and recommendations of our geotecl�nical engineering study for the site of a proposed residential subdivision in Everett, Washington. The Vicinity Map, Plate 1, iliustrates the general location of the site. Development of the properly is in the planning slage, and detailed plans were not made available to us. The site plans provided to us prior to our explorations depicted the proposed apartment building lor.ations and floor elevations, along with topographic information. Based on this information, we understand that the project development includes three buildings, all with lower level parking mostly surrounded with surface parking. Two L-shaped buildings will be at the norlhwestern and southwestern porlions of the site, while a T-shaped building will be located near the middle. Finish floor elevations for the buildings will range from 51 feet to 70 feet. �xcavation depths of as much as 20 feet in the western portion of the site are anticipated. Several feet of fill will be required in the eastern part of the project to achieve the desired floor grade. SITE CONDITIONS Surface The nearly rectangular site covers approximately 4.5 acres and is currently vacanl. It has about 600 feet of frontage along the eastern side of East Marine View Drive and an average depth of about 335 feet. The 11th Street right-of-way, partially improved to provide access to neighboring residences, borders the southern property line. The property is relatively flat from East Marine View Drive eastward for about 30 to 40 feet then drops moderaleiy to steeply 10 to 15 feet in elevation. A second flat area that has the appearance of a former haui road extends nearly across the property from north to soulh. Continuing eastward, the ground slopes gently downward to the eastern property line and beyond. Topographic relief across the site from west to east is about 50 feet. The property is well-vegetated with trees and dense undergrowth. Concrete elements which appear to be a foundation for a small building were found near the center of the southern half of tlie site. Subsurface The subsurface conditions �vere explored by excavating ten test pits at the approximate locations shown on lhe Site Exploration Plan, Plate 2. The field expioration program was based upon the proposed construction and required design criteria, the site topography and access, the subsurface conditions revealed during excavation, and on the scope of work outlined in our proposal. The test pits were excavated on July 24, 1998, with a trackhoe. A geotechnical engineer from our staif observed the excavalion process, togged the test pits, and obtained representative samples of rn�ii�nn�..ri i.�xrs.rnc
