There is a hole from my driveway side underneath the concrete curbside . It appears that the street support base maybe is or has collapsed under the asphalt. The asphalt is showing stress lines from in front 325 and 351 Avenue NE driveways.
A fiber optic cable maybe required to checkout the erosion depth & width.

R. The concrete curbside has shifted out of alignment. Also the area was the high point towards the street’s Stormwater drain. There is small drain pools developing.
