7500 HARDESON RD Geotech Report 2022-10-25

I Geoteehnical.Engineering Report Hardeson Road Retail SSGC Everett,Washington. SSGC Project No. 18072 September 18,2018 Field Exploration Procedures Our field exploration for this project included five test pits and one infiltration test completed on August 30, 2018. The approximate locations of the explorations are shown on Figure 1, Exploration Plan. Exploration locations were determined by pacing from site features. Ground surface elevations referenced on the logs were inferred from drawing titled "7-11, 7500 Hardeson Rd Everett", by AHL (dated 5/2/2018). Test pit locations and elevations should be considered accurate only to the degree implied by the means and methods used. A private excavation company subcontracted to SSGC dug the test pits. Soil samples were collected and stored in moisture tight containers for further assessment and laboratory testing. Explorations were backfilled with excavated soils and tamped when completed. Please note that backfill in the explorations may settle with time. Backfill material located in roads or building areas should be re-excavated and recompacted,or replaced with structural fill. The following logs indicate the observed lithology of soils and other materials observed in the explorations at the time of excavation. Where a soil contact was observed to be gradational, our log indicates the average contact depth. Our logs also indicate the approximate depth to groundwater(where observed at the time of excavation). along with sample numbers and approximate sample depths. Soil descriptions on the logs are based on the Unified Soil Classification System. r 1 1 1 I I I 1 A-1
