ADaPT Engineering, Inc. Western Wireless Corporation AMPT Job No,WA98.993 April I, 1998 Page I PROJECT DESCRIPTION The host parcel is located at 319 76th Street SW in Everett, Washington. The Project site is that of an existing water reservoir for the City of Everett, and currently supports an existing guyed tower and a wooden pole antenna. The project site and surrounding area are shown on the attached site vicinity map (Location Map, Figure 1). It is our understanding that current development plans call for replacement of an existing wooden pole with a 100-foot monopole tower construction of associated equipment cabinets. The attached Site and Exploration Plan (Figure 2) shows the approximate location of the proposed cellular tower lease area in relation to other site features and the fenced compound. It should be emphasized that the conclusions and recommendations contained in this report are based on our understanding of the currently proposed utilization of the project site, as derived from written information supplied to us by Western Wireless Corporation. Consequently, if any charges arc made to the project, we recommend that we review the changes and modify our recommendations, if appropriate, to reflect those changes. EXPLORATORY METHODS We explored surface and subsurface conditions at the project site on March 26, 1998. Our surface exploration consisted of a visual site reconnaissance. Our subsurface exploration consisted of advancing one soil test boring to a depth of approximately 30fcet below the existing site grade. The location of the boring, designated as B-1, is shown on the attached Site and Exploration Plan (Figure 2). The specific location and depth of the exploration performed was selected in relation to the proposed site features, under the constraints of budget and site access. The location of the boring and other features shown on Figure 2 were obtained by hand-taping from existing site features. As such, the exploration location shown on Figure 2 should be considered accurate to the degree implied by the measuring methods used. Boring Methods Boring B-I was advanced on March 26, 1998 using a truck mounted hollow-stem auger drill rig, The drill rig was operated by an independent company working under subcontract to ADaPT. A geotechnical engineer from our firm continuously observed the boring, obtained representative soil samples, and logged the subsurface conditions. Aller the boring was completed, the borehole was backfilled with a mixture of soil cuttings and bentonite chips.
