9 CASCADE GEOTECHNIrAL INC. 1.0 ViTRODUCTION Group West Associates, Inc. requested Cascade Geotechnical, Ire.,, to conduct a geotechnical investigation at the Evergreen Textile Services Site located in Everett, Washington. This report summarizes the findings of our field investigation, presents geotechnical conclusions, and provides preliminary recommendations for the proposed project. Jack Johnson of Jon -Dahl Properties granted authorization to proceed with this project on May 9, 1994, by signing our Proposal Letter dated April 27, 1994. 2.0 PURPOSE AND SCOPE The purpose of this study was to investigate the surface and subsurface conditions at the site in order to formulate conclusions and provide preliminary geotechnical recommendations for the construction of two (2) tilt -up panel warehouses and office buildings with associated parking, drive, and load -unload areas. Our scope of work for this project included the following: • conducting a geotechnical surface and subsurface investigation • a review of information contained in our library and files • the preparation of a geotechnical engineering report During the study, our scope of work was modified to include the excavation of four (4) trackhoe test pits within the proposed wetlands mitigation area. We understand this information will be used by the project's Wetlands Consultant for mitigation design. Subsurface information was obtained in the building areas using hand -operated auger and cone penetration equipnent. The scope was later increased again to include reinforced wall design and pavement section design. This report addresses the site's surface and subsurface conditions, and presents conclusions regarding the geotechnical suitability of the site for development. This report also provides preliminary geotechnical recommendations for: 0 subgrade preparation and grading
