The flag of New York City also features beavers. https://en.wikipedia.org/wiki/Flags_of_New_York_City

Edit: it's clearer in the seal of the city https://en.wikipedia.org/wiki/Seal_of_New_York_City

The Astor Place subway station also contains several beaver tiles / bas-reliefs, because John Jacob Astor made his fortune with beaver pelts. EDIT: see https://www.nyhistory.org/blogs/beavers-john-jacob-astor
