TRN-10.12 - Boring/Test Hole Permits


Administrative Rule Adopted by Bureau of Transportation Engineering & Development Pursuant to Rule Making Authority



I. Definition

Borings and test holes are drilled holes or dug sampling pits in the right-of-way. They are to be plugged, sealed and resurfaced within 5 days of initial drilling or digging. They may fall under State well drilling regulations if they make contact with the water table or if water is taken from the borings. Borings are typically used to obtain soil samples to design building foundations, or to test for possible releases from underground storage tanks or contamination of soil by hydrocarbons, or other hazardous materials.


II. Administrative Rule for Boring / Test Hole Permits

Application may be made through Portland’s Office of Transportation, Street Systems Management. Call 503.823.5185 and ask to speak with the technician that issues test bore permits.

Boring or digging for soil samplings in the right-of-way is a last resort and should only be permitted if the work can not be performed on private property.
