5034 OCEAN AVE Geotech Report 2022-10-25

4 51xx Ocean Avenue (Parcel#00571700100100) November 1, 2017 Everett, Washington Project#17110 Subsurface Exploration, Geologic Hazards, and Preliminary Geotechnical Engineering Report Introduction The purpose of this study was to gain subsurface information to be utilized in the design and construction of a new single-family residence on the subject property. The proposed construction will consist of grading, possible steel pipe pile installation, foundation subgrade preparation and building construction. Authorization to proceed with this study was provided by Paul Bustard of Bustard Custom Construction, Inc. This report was prepared for Mr. Bustard and his agents for specific use in support of this project. The location of the subject property is shown in the attached Vicinity Map and the locations of the subsurface explorations completed for this study are shown in the attached Site and Exploration Plan. Site Conditions The subject property is located at 51xxOcean Avenue in Everett,Washington. The property is rectangular and based on a review of the referenced site plan (Omega Engineering, Inc.),the property was 13,980 square feet in size. Portions of the property are relatively flat, and portions slope moderately to steeply from the south toward the north. The total elevation change on the subject property was on the order of 20 feet. The subject property is bordered on the east by Ocean Avenue and on all other sides by other residential properties. There is an easement across the southern edge of the subject property. The subject property had been previously graded in association with the subdivision of the "parent property" and likely graded in conjunction with the development of the property to the south. There was no standing or flowing water on the property at the time of our fieldwork. Though there were some steep slopes onsite,these slopes were well vegetated and we did not observe any signs of significant erosion or soil movement. Subsurface Conditions Subsurface conditions on the property were inferred from a visual reconnaissance of the property, a review of the referenced geologic map (Minard, 1982), referenced online resources, andthree exploration pits excavated with a track mounted excavator. The exploration pits allowed observation of the near surface soil and groundwater conditions. Observations of the in-situ relative density of the soil were made as the excavations progressed.The exploration pits were observed and logged by the undersigned engineering geologist and immediately backfilled. The locations of the subsurface explorations are shown in the Site and Exploration Plan and the exploration pit logs are attached to this report.
