1610 SE EVERETT MALL WAY Geotech Report 2022-10-25

Subsurface Exploration, Geologic Hazard, and Krebs Property Preliminary Geotechnical Engineering Report Everett, Washington Project and Site Conditions Paints). The tax identification number of the site is 28051800400300. The property is bounded to the west, north, and east by Everett Mall Way, the Interstate 5 (I-5) on-ramp, and the I-5 right-of-way. The topography of the site generally slopes gently down toward the southeast at an average gradient of less than 5 percent. The topography steepens slightly over a height of approximately 4 to 5 feet near the southeast property corner. East of the site, between the eastern property boundary and I-5, the topography steepens to a visually estimated gradient of approximately 20 to 30 percent. The subject property is lightly forested by mostly young deciduous trees with some conifers and moderate to thick brush. Our understanding of the proposed project is based on review of a topographic site plan and a preliminary building layout plan provided by BPH Assets Corporation, and on discussions with Mr. Alexis Chartouni of BPH Assets Corporation and Mr. John Cherry of HBA Design Group. It is our understanding that current plans call for the construction of a self storage facility to consist of two buildings. The proposed locations of the buildings are shown on the Site and Exploration Plan, Figure 2. The conceptual plan also includes the possible use of one or more rockeries for grade separation. 3.0 SUBSURFACE EXPLORATION Our field study included excavating a series of exploration pits to gain subsurface information about the site. The various types of sediments, as well as the depths where characteristics of the sediments changed, are indicated on the exploration logs presented in the Appendix. The depths indicated on the logs where conditions changed may represent gradational variations between sediment types in the field. Our explorations were approximately located in the field relative to known site features shown on the topographic site plan. The conclusions and recommendations presented in this report are based, in part, on the exploration pits completed for this study. The number, locations, and depths of the explorations were completed within site and budgetary constraints. Because of the nature of exploratory work below ground, extrapolation of subsurface conditions between field explorations is necessary. It should be noted that differing subsurface conditions may sometimes be present due to the random nature of deposition and the alteration of topography by past grading and/or filling. The nature and extent of any variations between the field explorations may not become fully evident until construction. If variations are observed at that time, it may be necessary to re-evaluate specific recommendations in this report and make appropriate changes. 3.1 Exploration Pits Exploration pits were excavated with a track-mounted excavator. The pits permitted direct, visual observation of subsurface conditions. Materials encountered in the exploration pits were February 13, 2007 ASSOCIATED EARTH SCIENCES,INC.
