Airspace Structure
I was working [a B737] on the STAR. I had to take him off the arrival for an unidentified VFR primary target flying through the approach corridor. [The B737] was told of the traffic and didn't see it; so I based [the B737] to miss the primary target and the primary target decided to turn towards [the B737]. [The B737] was based high and close to breaking the noise restriction. [The B737] eventually saw the traffic and it was no factor.This is a daily problem and someone is going to eventually get hurt. There needs to be an airspace design change. VFR targets constantly fly through the approach corridor at bad altitudes that conflict with aircraft on final or turning base. Often they are primary targets with no transponders and high enough to be a major concern. This situation is very bad and nothing seems to be happening about it.
P80 TRACON Controller cancelled an arrival's STAR and vectored the aircraft to avoid an unidentified VFR aircraft flying through the final approach course.
