00017636 Exhibit G Site Maps.docx

This document is an Exhibit G containing site maps for a Scope of Work and Technical Specifications related to a diatomaceous silt research drilling contract involving Oregon State University (OSU), Portland State University (PSU), and the Oregon Department of Transportation (ODOT). The project involves providing seismic cone penetration testing with pore water pressure measurement (SCPTu) as part of a geotechnical investigation at the Wikiup Junction site, which is known to be underlain by diatomaceous soils. The site maps depict the Vicinity map and detailed site view for Wikiup Junction explorations, with specific notation of potential CPT (cone penetration test) sites and borehole locations. Access to the East CPT site locations is from the North after Burgess Road (marked with an orange star), while access to the West CPT site locations is from the South off Highway 97 (marked with a blue star). The project work is to be contained within the ODOT Right-of-Way, with the green line on the detailed map representing the general boundary of this right-of-way.

Critical safety restrictions are clearly delineated on the site maps: no vehicles or personnel may cross the railroad tracks depicted as a red line on either map, and all work personnel and equipment must remain at least 50 feet from the tracks during project execution. These maps serve as essential planning documents for bidders to understand the geographic layout, access points, and operational constraints of the research drilling contract.
