If I'm right, Southridge actually had trash spawning. This was during the very early iEra times. But since no one really goes to Southridge often, the trash spawning doesn't happen anymore at Southridge.
That's fine. Now we have a bigger player count. The area deserves to become equal to the rest. I only use the trash center down there when I forget to sell. However, it is nice that it's clean... Less traffic I guess...
