Narrative:

VFR aircraft transitioned through the arrival corridor at 6500 ft. This was in an area where arrs transition through 7000 ft to 5000 ft. I provided vectors to avoid the traffic. These aircraft are in dangerous position -- especially during heavy arrival traffic. Implementation of class B airspace would alleviate the problem.
