Subsurfate Ezplorarion, Geologic Hazard, liibitskiy Reside»ce and Geo�ethnica!Engineering Heport L•verert, 11�ashingta: Project and Site Conditions 2.0 SITE AND PRO]ECT DESCRIPTION The project consists of the construction o[ a ne�� residential building at Uie above-referenced location. The residence is to be multi-story �vith a daylighl basemenUgarage, conventional foundations, and slab-on-grade floors. Foundation loads are expected to be relatively light. Thc property is bordered to U�e north, south, and west by single-family residences, and to the east by Friday Avenue. The site gencrally slopes to the east and sligh.ly south. Partial grading has already Ucen performed, but due to perniitting issues, has since been discontinued. Tlie grading consisted of 8 to 10 fect of cut along the northern and �vestern portions of the property. Thc exposed cuts have since been faced with an ecology block ��all and soil reinforcement. VVe expect ihat the �.vall bc removed and rebuilt priar to proceeding �eith construction. 3.0 SUBSURI�ACL- GXPLORATION Our field study included oUserving existing cuts and observing an cxploration pit on thc sitc. � The various types of sedimenis encountered during die excavation, as well as the depth whcrc the charac[eristics of the sediments changed, are indicated on the exploration log presented in the Appendix. The deptU indicated on the log where conditions changed may represent gradational variations bet��een sediment types. Our exploration was approximately located in the field by referencing known site features, and Qie exploration pit locations have been included on Ihe attache� "Site and Gxploration Plan," Figure 2. The conclusions and recommendations presenicd in this report are based, in part, on the observed cuts and the eXploration pit completed for this study. The number, location, and deptli of the on-site exploration were completed witl�in sitc and budgctary constrain!e. Because of the nattire of explorarory work below ground, interpretation of suUsurfacc conditions may bc nccessary. It should be noted that differing subsurface conditions may sometimes be present due to the random namre of deposition and thc alteration of topography by past grading and/or filling. The nature �nd extent of any variations beyond our field exploration may not become fi�lly evident until construction. If variations are observed at tl�at time, it may Ue necessary to rc-cvaluate specific recommendations in this repnrt and make appropriate cUanges. 3.1 Gxploration Pit The exploration pit was excavated by thc clicnt. The exploration pit, as well as the observed cuts, permitted direct, visual observation of subsurface conditions. Materials encountered in the exploration pit �vere studied and classificd in the field by a georechnical engineer from our finn. 7'he exploration pit was backfilled immediately after examination and logging.
