This is the old reservoir south of Children's Hospital and North of the Bloomingdale residential area.
Bounded by Michigan Avenue to the North, Channing Street to the South, North Capitol Street to the East and First Street to the West. Notionally 8 square blocks since North Capitol to is quite wide and there will be a new street down most of the middle of it (overall a street grid of some sort is re-established).
A quick summary is two blocks of hospital/health care related buildings.
Then two blocks that combine multifamily housing more health care and a grocery story
Then two blocks of townhouses
Last two blocks are green space/park with a community center.
