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.
Several months ago the city has been out and placed bait boxes. I have bated and re-bated bait boxes every day for the past month, all with no improvement. Pest control professionals ensure me that the problem can’t be fixed without removing the nesting opportunity. The side yards of this property are stacked 6’ deep with junk. These rats are regularly chewing through my window screens.
