If I hear one more person claim "Boulder won't let CU build xxxxx" I'm going to freak out. I'll say this again - Boulder can't stop CU from building anything they want to. CU is a state institution and is not bound in any way by Boulder rules and regulations. If CU wanted to completely tear down the CEC and replace it with a 40,000 seat arena, complete with private hot tubs and plasma TV's for each attendee, they could do it. Boulder wouldn't be able to do a damn thing to stop it.
Boulder won't let CU fans freak out, so there.
