Since no one jumped in to help on this one, Ill throw what I know, which is next to nothing. I used to work for a millwright contractor, and we worked at a mill in Coosbay everyweekend for almost a year. I didn't do any fishing while i was down there, and Im not sure about any jetty fishing. But I do think I have seen/ think its possible to throw some rings off the board walk in downtown Coosbay, and bobber fish or throw spinners in the same location.
