GeoTest Services, Inc. October 8, 2021 2405 Hillside Lane, Everett, WA Project No. 21-0845 PURPOSE AND SCOPE OF SERVICES The purpose of this evaluation is to establish general subsurface conditions beneath the site from which conclusions and recommendations pertaining to project design can be formulated. Our scope of services includes the following tasks: • Explore soil and groundwater conditions underlying the site by advancing 3 test pit explorations via a track -mounted excavator provided by Fullwiler Construction, Inc. • Perform laboratory testing on representative samples to classify and evaluate the engineering characteristics of the soils encountered and to assess on -site infiltration capability. • Provide a written report containing a description of subsurface conditions and exploration logs. The findings and recommendations in this report pertain to site preparation and earthwork, fill and compaction, seismic design, foundation recommendations, concrete slab -on -grade construction, foundation and site drainage, infiltration feasibility, temporary and permanent slopes, geotechnical consultation, and construction monitoring. • Assess Geologically Hazardous Areas (if present) per Everett Municipal Code (EMC). PROJECT DESCRIPTION The rectangular -shaped, approximately 0.68-acre subject property is located west of 24th Ave. W. and south of W. Mukilteo Boulevard in Everett, WA. The project site contains three lots (Lots 2, 3, and 4) of a 4-lot short -plat. Lot 1 is located to the south of the proposed development (2405 Hillside Drive). This lot contains a single-family residence and will remain unchanged as part of the new development. The owner of Lot 1 currently owns the three lots described here as of the writing of this report. An existing driveway originating from 241h Ave. W. serves as access to the future homes. GeoTest understands that the subject property will be developed into three single family residences. Due to the presence of an approximately 32-foot-high slope that comprises the subject property, it is expected that some site grading will be required to establish the 3 buildable lots. Preliminary information regarding infiltration or stormwater detention facilities was not available at the time that this report was written. An existing stormwater detention facility exists in the proximity of the private road. Design details of this facility were unavailable at the time that this report was written. 1
