Potholing_Table_Updated_Stationing.xlsx

This is a potholing data table from the City of Hayward, Oregon, documenting utility location investigations conducted in 2020 by Otak along SW 22nd Street and SW Juniper Terrace. The spreadsheet records 29 pothole locations with corresponding construction station markers, utility types (water, sewer, gas, communications, power, and storm), pipe sizes, materials, and depths to the top of pipe. The data identifies utilities across multiple service lines, including water mains ranging from 1 to 12 inches in diameter, sanitary and storm sewer laterals, gas lines, power and communications conduits, and copper water service lines. Notable findings include cast iron and ductile iron water pipes at depths varying from 22.8 to 128.9 inches, several utilities marked as "Did Not Find" (DNF), and multiple locations where swaths were used to locate utilities due to congestion or unclear positioning. The pothole investigation results include annotations regarding asbuilt discrepancies, connection points, and the inability to locate certain utilities despite search efforts.

This potholing data directly supports the City of Hayward's CIP 4136 project for SW 22nd Street waterline and sewer improvements, which encompasses approximately 4,000 linear feet of zinc-coated ductile iron potable water pipe installation in sizes of 4", 6", and 8", along with thirteen waterline connection details and two sewer cleanout replacements with new manhole structures. The pothole information provides essential baseline utility conflict identification necessary for the project's design and construction planning phases, enabling contractors to anticipate underground obstructions, plan traffic control measures, and coordinate with utility companies for potential relocations or protective measures during construction activities along this high-traffic residential corridor.
