Crystalline Cove - Finally back on the exchange!!!

Community Center Plaza is a name that doesn't do it justice, in my opinion. That Plaza is way too pretty! Many plazas where I live are named for their location, so Crystalline Plaza would work. Or Crystal Plaza. I have heard of a "Central Plaza" but that is just the name of an office building. But it might work for your purpose.

I'm glad I could be of help explaining what a plaza is. What you have built there definitely fits the definition of a plaza in the USA!
