DAY CARE FACILITY UTILITY LOCATE

Plateau Geoscience Group conducted a Ground-Penetrating Radar (GPR) survey to determine whether a sewer line was present in an area proposed for construction at a day care facility in Portland, Oregon. The GPR survey was made in the facility’s entrance area and in the central portion of the parking lot. The raw data was collected onsite then processed using GPR Slice v7.0 software. A sewer line was not identified in the entrance area, and a shallow trench ending at a subcrop of basalt was identified in the central portion of the parking lot.
