I found a more detailed map for Burnside Phase 12
HERE.
This one shows that the Dartmouth Crossing Lands aren't specifically labelled as commercial. It also shows the new "Atlantic Logistics Park" in detail.
Anybody find it amusing that Burnside is soo big we had to split it into three/four "areas" (Burnside, City of Lakes, DC, Logistics Park) just so when someone says Burnside we aren't thinking of something the size of a normal town?
