00018072 Exhibit G Site Maps.docx

This file consists of site maps (Exhibit G) supporting a geotechnical investigation project involving the State of Oregon, the Oregon Department of Transportation (ODOT), Oregon State University (OSU), and Portland State University (PSU). The site maps document the location and layout of the investigation area at Wickiup, where drilling, soil sampling, and in-situ testing activities are being conducted as part of Phase 3 of project SPR892_879. The investigation focuses on a site underlain by diatomaceous soils and is being performed to support settlement and foundation analyses for the joint research initiative among the participating agencies and academic institutions.

The site maps provide visual representation of the drilling locations, access points, and relevant site features necessary for executing the geotechnical investigation work. These maps serve as a reference document for contractors and project personnel involved in the drilling and testing operations at the Wickiup site. The exhibit supports the overall project scope by clearly delineating work areas and facilitating coordination among ODOT, OSU, PSU, and contracted drilling and testing services.
