Across the strip from Lake City is Central Park. Central Park is a beautiful area, with as many parks as houses. This area is also home to four arcologies. The furthest south suburb is Southwest City. Southwest City includes everything south of the freeway, including Planetarium Park, and stretching east all of the way to New River.
New River is the second smallest suburb, across the freeway from Big Lake.
P.S. Check out some of the names on the roads and freeways. They come from an episode of the Simpsons that was on while I was constructing some of the city. Try and figure out which one. Check the freeway names especially. It went through two major design phases.
