Aug, 31. 2004 3:46PM CHARLES MORGAN & ASSOC, No, 0044 P, 3 • GEOTECHNICAL ENGINEERING.STUDY Proposed 31-Unit Apartment Building Rucker Avenue and 37th Street Everett,Washington This report presents the findings and recommendations of our geotechnical engineering study for the site of the proposed 31-unit apartment building in Everett, Washington. The Vicinity Map, Plate 1, illustrates the general location of the site. We were provided with site plans and a topographic map. Ostergaard Robinson & Associates developed these plans, which were produced in October of 1990 and revised between December 1991 and January 1992. Based on these plans, we understand that the building will have a lower floor varying in depth from approximately 4 to 13 feet below existing grades. SITE CONDITIONS Surface The generally rectangular, currently vacant site is located at the northeast corner of Rucker Avenue and 37th Street in Everett, Washington. It is bordered to the north by an existing residence, to the east by Rucker Avenue, to the south by 37th Street, and to the west by Grand Avenue. The site has a gentle slope down to the north. There is a cut slope approximately 10 feet in height at the property line on Rucker Avenue which is covered with bushes and shrubs. There is a rockery of approximately 4 feet in height.at street level at the base of this slope. The site had been cleared and graded somewhat. Subsurface The subsurface conditions were explored by excavating four test pits at the approximate locations shown on the Site Exploration Plan, Plate 2. The test pits were excavated on February 1, 1999, with a trackhoe. A geotechnical engineer from our staff observed the excavation process, logged the test pits, and obtained representative samples of the soil encountered. "Grab" samples of selected subsurface soil were collected from the backhoe bucket. The Test Pit Logs are attached to this report as Plates 3 and 4. All four test pits encountered 1 to 4 feet of fill overlying dense glacial till. The glacial till was generally cemented, although there were some areas that contained gravelly, silty sand. Test Pits 1 and 3 encountered hard silt at approximately 10 feet.below grade. All test pits were excavated about 1 to 2 feet below the planned basement grade. Test pits depths ranged from 11 to 13 feet. The final logs represent our interpretations of the field logs and laboratory tests. The stratification lines on the logs represent the approximate boundaries between soil types at the exploration locations. The actual transition between soil types may be gradual, and subsurface conditions can vary between exploration locations. The logs provide specific subsurface information only at the locations tested. The relative densities and moisture descriptions indicated on the test pit logs are interpretive descriptions based on the conditions observed during excavation. at GEOTECH CONSULTANTS,INC.
