Description of specimen

I did not find any larvae or insects, just d shaped holes. There were dead branches on this tree, which further supported my educated guess about the holes.

Commentary

Thank you for your report! Those holes look suspicious. Here is the ODF EAB website with resources to help identify ash trees and more signs of EAB:

I visited this site yesterday and found no evidence of EAB. The tree circled in the picture is not ash. There were 3 exotic narrow-leaf or Raywood ash on Western St. I inspected them and found no exit holes or other EAB signs. There were a couple of wild Oregon ash on the east side of the bike path, next to the Willamette River. They looked healthy.

Location

There are several trees that I believe are Oregon Ash along this stretch of the riverfront park path. The tree where I saw several D shaped exit holes was on the west side of the path, east of the large parking lot, 3rd tree from corner of Western.
