The Mount Vernon-Belvedere Association cites the borders as Interstate 83 to the east and north, Howard Street to the west. and Mulberry Street to the south. The city's Commission for Historical and Architectural Preservation draws a slightly different boundary, putting the southern limit at Hamilton Street and the western at Eutaw Street. The Midtown Community Benefits District — a citizen-run neighborhood improvement group that represents Bolton Hill, Charles North, Madison Park and Mount Vernon-Belvedere —uses yet another boundary. Technically, Mount Vernon and Midtown-Belvedere are two separate areas, but they're sometimes considered one neighborhood and simply referred to as Mount Vernon.
