BOX 37 <br />WILSONVILLE, OR. 97070 <br />PH: 503-682..0822 <br /> <br />CARLSON TESTING, INC. <br />JAMES D. IMBRIE EHGRqEER <br />P.O. BOX 23814 TIGARD, OR. 97'281 <br />PHONE: 503-684-3460 <br />FAX: 503-684-0954 <br /> <br />During the flood of Felmmry of 1996 our property on tim Willmne~e river suffered a <br />significant landslide. In order to protect our property and residence we propose <br />constngting a retaining wall. <br /> <br />I have retained James Imbrie an eng/neer with Carlson Testing, Inc. who will ceaify the <br />structural integrity of this stmctore. James Imbrie and other colleagues from his office <br />have reviewed the slope failure on numerous occasions. On 6-%97 Carlson Testing <br />performed two sample borings to a maximum depth of 30 feet. Soil samples were <br />collected at five foot intervals. These samples are currently being tested for water <br />content and soil classification. James lmbrie investigation will include geoteehnical <br />studies consisting of field explorations, laborato~ testing and engineering analyses. <br /> <br />James Imbfie has recommended the retaining wall as described below. James Imbrie a <br />registered engineer will give his stamp of approval for this structure and is forthcoming. <br />I am submitting this application now to hopefully expedite the permit process because <br />the window of opportunity to complete this project is limited. Due to weather and other <br />problems out of my conlrol testing was not able to begin until just reeently. I would <br />anticipate further damage if the projcct is not completed this summer. <br /> <br /> <br />
