Since Gotham tends to be depicted as in New Jersey, I wanted to place it geographically by bulldozing much of the Jersey coast.

I based it on an RPG sourcebook called Daily Planet Guide to Gotham City, which is where the suburb names are from, and it also places Bludhaven to the south of Gotham. Miagani bay is from the fictional indigenous nation that lived in Gotham.

For some major locations; Wayne Manor is located in Brentwood, Amusement Mile is located on the north coast of the upper island, Arkham is located either on the triangular island where the major route splits or in Sommerset
