00017706 Exhibit G Site Maps.docx

This is an Exhibit G Site Maps document for a geotechnical drilling contract involving the Oregon Department of Transportation (ODOT), Oregon State University (OSU), and Portland State University (PSU) for diatomaceous silt research at the Wickiup Junction site. The project encompasses drilling, sampling, and in-situ testing services to support settlement and foundation analyses at a site underlain by diatomaceous soils. The scope includes establishment of borehole (BH) sites and Cone Penetration Test (CPT) locations, with specific entry points designated: the East BH site accessed northward after Burgess Road (marked with an orange star) and the West BH site accessed southward off Highway 97 (marked with a blue star). All work must be contained within the ODOT Right-of-Way, and personnel and vehicles are prohibited from crossing railroad tracks depicted on the site maps, with a mandatory 50-foot buffer maintained from the tracks during all operations.

The document provides detailed vicinity and site-specific maps illustrating potential exploration locations at Wikiup Junction, with the green line representing the general ODOT Right-of-Way boundary. The site maps serve as critical planning documents for contractors to understand the geographic constraints, access routes, and safety parameters governing the drilling operations. No pricing terms, bidding procedures, contract duration, award dates, or funding details are specified within this exhibit document, as it functions solely as a technical reference for site conditions and operational boundaries.
