Beverton is a bit far for me, as I live in Eugene.
But, surf perch are an option, as well as jetty fishing from the rocks, if you're nimble enough to do it.
I'm not, but I do have a small boat I use to fish in the bays for both crabs and the rock fish that hang around the jetties.
Kayaking the jetties is also an option. Some even fish outside the bays on their yaks. Checkout rodgerdodger's posts for examples.
