New Arkham [5, 99]
Prior to the outbreak, this block housed the eastern half of The Connors Motel, a poorly constructed "Public Safety Hazard." The structure was slated for demolition in mid-2005 but, due to the presence of radioactive compounds in the building's paint, demolition progressed slowly. By the time of the zombie outbreak, only the eastern half of the motel, sitting on this block, was destroyed.
Scientists from The Wreford Building claim that, on a clear night, the glow of radioactive paint can be seen all the way from space (via necronet).
