Box 598 <br /> Everett, Washington 98206 <br /> Geotechnical Engineering Evaluation <br /> Stadium Flowers Addition <br /> 3620 Broadway <br /> Everett,Washington <br /> NGA File No.983917 <br /> Dear Mr.Van Winkle: <br /> We are pleased to submit the attached report titled "Geotechnical Engineering Evaluation — Stadium <br /> Flowers Addition—3620 Broadway—Everett, Washington." This report summarizes the existing surface <br /> and subsurface conditions within the site and providesrecommendationsfor the proposed site <br /> improvements. Our services were completed in general accordance with the proposal signed by you on <br /> February 24,2017. <br /> The site is situated on a 0.27-acre split rectangular lot, composed of a gentle east-facing slope that <br /> descends from the western property line to the eastern property line along Broadway. The site is <br /> composed of an existing parking area located within the eastern portion of the property, and a proposed <br /> building addition excavation on the western portion of the property. The excavation covers an area of <br /> approximately 150 square yards, with a maximum depth of 4.8 feet below the adjacent concrete and <br /> asphalt-paved surfaces. The proposed development plan includes the construction of an addition for <br /> Stadium Flowers in the form of a separate structure within the northwestern portion of the site,along with <br /> new parking and utilities. Final grading or drainage plans have not been developed at the time this report <br /> was prepared. <br /> We explored the site with four hand-auger boreholes extending to depths in the range of 2.5 to 8.5 feet <br /> below the existing ground surface. Our explorations indicated that the proposed new building footprint <br /> area is generally underlain by loose to medium dense undocumented fill soils underlain by medium dense <br /> or better,fine to medium sand with trace gravel soils that we interpreted as native glacial outwash soils at <br /> depth. <br /> We concluded that the site was generally compatible with the planned improvements. We recommend <br /> that the new structure be founded on the medium dense or better native glacial soils for bearing capacity <br /> and settlement considerations. These soils were generally encountered at shallow depths less than 2.4 feet <br /> below the current excavation, which corresponds to approximately 2.4 to 6..4 feet below the projected <br />
