Colonade Sq is an alley through what looks like a condo or duplex style development. It is private and apparently chained off as a matter of habit at the northern end and only open at the southern end.
The map should be adjusted to show Colonade Sq as Private Road and as disconnected from Rose Ave on the north.

Please feel welcome to respond to and close the UR after looking into this, I’m definitely not proprietary about it.
