EXHIBIT A — SCOPE OF SERVICES <br /> LARIMER ROAD STABILIZATION — 6700 AND 8400 <br /> EVERETT, WASHINGTON <br /> FILE NO. 0661-119-00 <br /> INTRODUCTION <br /> GeoEngineers is pleased to present our scope of services to the City of Everett(City)to provide geotechnical <br /> engineering services to evaluate the embankment stability and provide alternatives to repair the roadway <br /> at two locations exhibiting on-going slope movement along Larimer Road. The two slope movement and <br /> pavement distress areas to be evaluated are located near the 6700 and 8400 blocks near the southern <br /> city limits. Our understanding of the project is based on our discussions during an on-site meeting with the <br /> City and our experience on similar stabilization projects along Larimer Road. <br /> PROJECT UNDERSTANDING <br /> Both areas exhibit slope instability and on-going severe tension cracks in the pavement. The road <br /> embankment is elevated roughly 10 to 15 feet above the valley floor with open ditches on the valley floor <br /> contributing to over-steepened slopes and embankment instability. We understand that cracking and slope <br /> creep near the 6700 block has been observed from about 130 feet south of the Red Barn to about 210 <br /> feet south. The crack continually reappears in the southbound lane. A recent overlay was observed in the <br /> area, but the beginning of a hairline crack was reappearing when we met on site with the City. <br /> Severe separation cracks were observed near the 8400 block (roughly 3 to 4-inch separation cracks with <br /> small holes/voids). A culvert crossing is located on the north side of this failure area, discharging into the <br /> ditch below the toe of the slope. <br /> SCOPE OF SERVICES <br /> Our services are requested to complete subsurface explorations as a basis for evaluating slope stability <br /> and alternatives to repair the roadway at the two locations. Support or development of plans and <br /> specifications will be completed in a subsequent phase, if requested. Based on our site visit with you and <br /> discussions, we propose the following scope of services: <br /> 1. Review existing data including available City as-built records, LiDAR data, geologic maps, <br /> and previous geotechnical reports completed in the vicinity. <br /> 2. Complete a geologic reconnaissance of the site areas to observe and document pavement <br /> distress, soil exposures, slope and seepage conditions, and to mark the proposed boring <br /> locations. <br /> GeoEngineers File 0661-119-00 Page 1 <br />
