What was the purpose of raising the Class C floor on the west side?
Just to
give aircraft there more room to operate without contacting approach?

To make it uniform.
The original floor of the CCAS was 2500 MSL on the east
(010-130) and 2200 MSL for the remainder.

There must be more to it than that. Lowering the east side to 2200 MSL
would have made it uniform and closer to the Class C standard of 1200 AGL.
Raising the west side moves further away from the standard. Why was the ten
mile ring made nonstandard to begin with?

Higher terrain.
