I call this map DK City - it starts out at the edges with small shacks and as it gets towards downtown the buildings get larger. The other feature is the city is laid out in a uniform grid with LOS from one side to the other so it should make for some good cat-and-mouse AFV action between buildings.
Below: view downtown from the south - if LOS is thought too long then it could be played in fog and rain.
