boomtown

I'm a little stuck... Click here to teach me more about this clue!

'prosperous but hardly quiet?' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'community' is the wordplay.
I cannot quite see how this works, but
'community' could be 'town' (I've seen this before) and 'town' is found in the answer.
The remaining letters 'boom' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...

Can you help me to learn more?
