One lane will be closed during drilling operations with no more than 15 minute delays, due to use of a truck-mounted drill rig. Drilling fluids will be contained and transported off site. Night work may occur (which is preferred) and no work will occur on weekends or any holidays. Borings will be backfilled with gravel and capped with asphalt. Total estimated time for geotechnical work is one week. Consultation with cultural resources staff indicates there is no archeological, traditional gathering, or cultural landscape impacts from these activities.
