About this file
This is a Draft Exploration Plan and Checklist Reference Document prepared for emergency response geotechnical drilling and sampling services in Jackson County, Oregon, specifically addressing three separate landslide locations along Highway 227 Tiller Trail Highway. The project encompasses three drill sites at milepost locations 43.1, 44.1, and 44.7, with each site requiring three drillholes at an estimated depth of 60 feet per hole, totaling 180 feet of drilling per location with 20 feet of coring per hole. The exploration plan details anticipated drilling methods including HQ3 coring, HSA techniques, and Standard Penetration Tests (SPT) at 2.5-foot intervals. Instrumentation requirements include slope inclinometers and vibrating wire transducers (VWT) to be installed at each drillhole. The anticipated start date is listed as TBD, with an estimated 4 to 5 days required for drilling operations at each site. Environmental clearance requests have been submitted to Jessica Bochart, though environmental clearance status and environmental restrictions remain to be determined.
The document indicates anticipated subsurface conditions of asphalt and dirt at all three locations, with no special sampling such as Shelby tubes expected. Erosion control requirements, utility locate ticket numbers, site access arrangements, right-of-way considerations, staging areas, and traffic control plans remain to be finalized (TBD). All three sites are identified under Emergency Response Landslide project designation with the same Environmental Response Assessment number (ERADMF25000) and are located within Jackson County, Oregon. The document serves as a reference checklist for project planning and coordination of the geotechnical exploration activities.
