The reason the starbases are where they are is thier purpose is to defend the wild frontier on the Klingon and Federation border from each other. Their not simply club houses thier being built for a specific purpose. Plus thier close I believe to New Romulus.
Cryptic designed the Starbases to be social zones. And, if they wanted it to look like an actual military base, then the little 'Ops' level wouldn't be there. Hence my point of giving the starbases an actual Operations Center like that of the Embassy's in addition to the General Area, which is currently the Ops level.
