Narrative:
Portland was landing runway 10. I had to vector aircraft X to avoid a mid-air collision with a primary only target departing vuo. I don't know what needs to be done. I keep filing these reports for the same issue and I am at a point where I think nothing will ever get done. Unfortunately there will probably have to be a near mid-air or another dangerous incident for something to change. Our airport configuration is very dangerous in my opinion. We have vuo airport near the approach end of runway 10L and on the east side there is ttd at the approach end of runway 28R. To further compound the situation there is spb and hio 15 miles northwest and southwest of portland [respectively] and aircraft fly constantly back and forth through the approach corridor at very bad altitudes that conflict with air carriers on a radar downwind or base leg. We need a procedure/airspace change that restricts the VFR aircraft to below 2000 feet in the approach corridor.
