Narrative:

We were [doing] a procedure where we land as many aircraft as possible on runway 26 to help out the tower from having to stop departures and cross the departure runway for aircraft that land runway 25L. This wasn't a causal factor. I had aircraft X on a northbound heading; assigned 040. As he was descending through 050; I noticed a target that appeared to have departed southbound; climbing out of 032. I instructed aircraft X to stop his descent and issued the traffic. The unidentified aircraft's flight path would take him just to aircraft X's left side. Aircraft X stopped at 045 and was looking for the traffic. At this point; the aircraft continued a climb and aircraft X responded to a TCAS RA. No separation was lost; and the unidentified aircraft stopped the climb at 038. Aircraft X advised he was climbing. There was another aircraft that the other final had; aircraft Y; that was going to land on the south side. I was going to go under aircraft Y with aircraft X; he was going to stay on top. I gave aircraft X the traffic and he advised me that he would stop at 050; and thanked me for the traffic. Both aircraft landed without further incident.this happens all the time. Aircraft depart ffz and skirt the bravo; which goes down to 040. Given the proximity to phx; it's imperative to get those [inbound aircraft] down so they can make the descent to land at the airport. We need a new bravo layout. This happens way too many times. The bravo needs to be changed and hopefully [reporting] will be the vehicle for which it is intended.
