The map of Neighborville both shown in the comic series and in the Battle For Neighborville: Founder's Edition trailer directly contradicts each other; it's implied that Neighborville is a small town in the comics, but the map of the town displayed in the aforementioned trailer shows Neighborville being far larger than a typical city.
As the Garden Warfare comic volumes depict the events of Garden Warfare 2 leading into Battle For Neighborville, it can be assumed that - when taking into account of all the maps (excluding Gnome-related locations) - Neighborville is large enough to rival a small country in sheer size alone.
The poles seen during zombie victory in Goopy Gully reveals that Neighborville is located in Canada, more specifically Vancouver, which can be seen if one looks closely at the location of the poles.
