r � SHANNON&WILSON,INC. IGEUI'ECIiHICAL REPORT I INTRAWEST SEAWAY EVERETT, WASHINGInN � 1.0 INT'RODUCTiQ1I I Th�s report presents the msults of our sub,urface eapiorddons and geotechnical engineering studies for the proposed buildings and associated drive and parldng areas at the Intrswest SeaKay site in Everett, Washington. The purpose of our work was W: 1) evaluate � subsurface soil and groundwater condi6ons at the site; 2) evaluace the shability of the slope I along the east property line and provide recommendadons for maintaining or imprwing its stability; and 3) prwide geotechnical recommendations for the development of the site and for the design and construc6on of the proposed facili6es. IOur work included ihe following: 1) reviewing the United States Geologic Survey map of I� the area W determine local geologic condidons, 2) nwiewing portions of Evemtt Municipal Code (EMC) 19.37, MDNS No. 37-89 (and the City Council's appeal decision) and a June � 18, 1993, letter from the City of Everett to Seafirst Bank regarding development at lhe site; 3) drilling 5 borings and ezcavating 21 test pits w determine subsurface conditions in the I proposed development area; 4) performing laboratory cests tn determine indea and engineering properties of the site soils; S) completing a geologic reconnaissance of the slope to identify soil exposures, seepage wnes, and any signiScant erosional or slumping amas; 6) compledng engineering analyses co develop design and construction recommendations; and 'n preparing this report. IThe work was done in general accoidance with the scope of work oudined in our proposal dated January 24, 1994, and in accordaece with the terms and condidons ouUined in the Agreement For Professional Senrices (GH-93) provided to Sierta Construction Company, Inc. (Sierra). This work was verbally authorized by Sierra on February 14, 1994. I I W-6693-01 1
