TCAS won't fly you into the ground on an RA, but 2000' - 3000' is plenty high to get RA guidance.
I'm guessing that its an area near or below the class b that VFR aircraft usually use to transit the area. Since its not a formally published VFR corridor, it's unofficial (pilot/local knowledge).
IFR traffic isnt required to be separated against non-participating VFR traffic that is outside of class b airspace. That's the issue here- the procedure takes aircraft outside of the protected class-b.
To the original poster, I'd be interested in knowing what airport/approach you're referencing.
