What city do you think Arthur's "Elwood City" is set in based on this map and other context clues from the show
My bet is Erie, Pennsylvania.
This was the town that the Author Marc Brown grew up in. The climate and topography shown in the show match.
There is a lake with beaches in the show that mirrors Presque Isle State Park on Lake Erie.
There is a mall called Millcreek Mall in the actual city of Erie.
The setting of the show has 4 seasons and gets snowy, which rules out the American South and much of the American West, leaving only the Midwest or Northeast as possible options.
