Perm .ting <br /> Subject: Geotechnical Engineering Report <br /> Landslide Repair <br /> Finley Residence <br /> 540 Alverson Boulevard <br /> Everett, Washington <br /> Dear Mr. Voelckers: <br /> AMEC is pleased to submit this report describing our geotechnical evaluation for the above- <br /> referenced project. The purpose of our evaluation was to derive conclusions and recommendations <br /> concerning repair for the landslide that occurred recently on the property of Bill and Katie Finley. <br /> AMEC recently completed a Geologic Assessment of Critical Areas and Buffer Management Plan for <br /> the Alverson-Maulsby Bluff, which includes the slope below the Finleys' property. <br /> As outlined in our proposal dated February 15, 2013, our scope of work was limited to a site <br /> reconnaissance, geotechnical research, engineering analyses, and report preparation; no explorations <br /> or laboratory tests were included. We received your written authorization for our evaluation on <br /> March 4, 2013. This report has been prepared for the exclusive use of Mr. and Mrs. Finley, Stirling <br /> Construction, Inc., and their consultants for specific application to this project in accordance with <br /> generally accepted geotechnical engineering practice. <br /> SITE AND PROJECT DESCRIPTION <br /> The site is located at the top of a steep slope, known as the Alverson-Maulsby Bluff, that descends <br /> westward to the Maulsby Swamp and the Everett Shoreline as shown on the enclosed Site Plan <br /> (Figure 1). The City of Everett has mapped the slope as a critical area due to erosion and landslide <br /> hazards. A surficial landslide occurred at the top of the slope in January 2013. The upper 2 to 3 feet of <br /> loose weathered soil slid due to rain saturating the loose surface soils and seepage from shallow <br /> perched groundwater. The width of the slide scarp was about 20 feet and the length was about <br /> 30 feet. <br /> AMEC Environment&Infrastructure, Inc. <br /> 11810 North Creek Parkway N <br /> Bothell,Washington 98011 <br /> (425)368-1000 Phone <br /> (425)368-1001 Facsimile <br /> www.amec.com W\_Projects\17000x\17245 Alverson-Maulsby Bluff Property LLC\17245-A\Geotech Report\Finley Geotech Report 130722.docx <br />
