About this file
This is a Test Hole Report Sheet prepared by VacX, a utility coordination service, documenting subsurface utility investigations along SW Hart Road and SW Sorrento Road in Beaverton, Oregon for the City of Beaverton's CIP 4211 project. The file contains detailed pothole investigation data for seven test holes (ZP-1, ZP-3, ZP-4, ZP-5, ZP-6, and ZP-7) conducted on July 17-18, 2025, identifying subsurface utilities including Ziply Fiber communications concrete encasements running east-west and north-south, NW Natural gas lines (2-inch epoxy steel), and City of Beaverton water lines (4-inch cast iron). Each test hole report includes precise measurements of pavement core thickness (ranging from 6 to 9 inches of asphalt concrete), estimated heights of utility structures (ranging from 2.20 to 3.45 feet), horizontal and vertical distances from established reference points, elevation data, and cross-sectional sketches indicating the orientation and material composition of discovered utilities. All investigations were conducted under VacX reference number V25-11092 and prepared by Jason Jones, with contact information provided for the Utility Coordination Service at (541) 505-5074.
The test hole investigations reveal varying cover depths over utilities, with vertical distances from pavement surface to utility tops ranging from approximately 2.24 to 4.96 feet depending on location and utility type. The reports document that no utility tell-tales were set at any location and note that potholes were relocated in the field based on utility locate findings to avoid conflicts with subsurface infrastructure. Measurements were taken from established reference points including storm crossing points with elevations of 216.39 feet, providing baseline data essential for the waterline installation project specifications in CIP 4211. The subsurface investigation data serves as critical information for the subsequent construction phase of the SW Hart Road traffic circle public waterline improvements, which involves installation of approximately 1,800 linear feet of zinc-coated ductile iron potable water pipe in diameters of 12, 8, 6, and 4 inches on this heavily traveled residential corridor.
