Thc drillinc ��cis I subcontracted. The exploration locations are shown in Figure 2. Details of Uic crploraiions are included in Appendix A. � 2.2 LABORATORY TESTING Soil samples obtained from die esplorations werc transponed to GeoBnginccrs' laboratory in Redmond and examined to confirm or modify field classifications. as well as �o cvaluate ' engineering properties of the soil. Reprcsentative samples were selected for laboratory tcsting ; wnsisting of se��eral moisturc content and density detertninations,as well as one consolidation test. � Tlie tests were perfomied in general accordance with test tnethods of the Amcrican SociMy for Testing and Materials (ASTM) or other applicable procedures. .Appendix B includes a bricf ' discussion of the laborarory tesu and test rcsults. 3.0 SITE CONDITIONS � Tlie following subsections describe the general surface and subsurface conditions at the site. Inrerprc[ations of the site conditions arc based on a site reconnaissance, previous cxperience at the � site,and the subsurface e�plorations. 3.1 GENERAL SURFACE CONDITIONS ( The site is located in an old sand and gravel pit at thc southeast corner of Hardeson Road and Shuksan Way in Everett, Washineton. The site is bounded on the west by Hardeson Road and on the north by Shuksan Way. Tlie south property line is near the toe of a fill slope that ��as � predominaNly consWcted last ��ear. The fill slope is up to abou[ 40 feet high and is inclined as steep as 1.5H:1V (horizontal to vertical) near the southeast proper[y comer. The fill was placed against an old mined pit vertical high wall that H�as about 90 feet high. Therc is a 20-acrc sediment � pond located south of the site with a water surface at about Elevation 470 fceL L.o[3 is locatcd e�st of the site and it has also been paded relatively flat. � The site generelly slopes do�tro from about Elevation 450 feet near the southeast comer to about L-Ievation 430 feet neaz the northwest comec The ground surface across the west, central, and northeast portions of the site is relatively 11at with about a 4-to 6-foot gain across the site. There is iabout a 16-foot elevation gain in the southeast corner of die site beginning at the south drainage ditch,see Figure 2. A surface water collection pond is locatcd in a fortner pit azea in the soudiwest ' comer of the site. Thrce surface water drainage ditches traverse the property and terminate at the pond. The central and largest ditch is about 3 to 4 (eet deep and 8 feet wide and begins near the L.ot I �� G e o [ n g i n c e r s 3 FilcNo. 75R4-002-00-1130�050101 ��.
