Existing Green and Grey ConditionsThere is a sharp visual difference between grey and green landscapes within Site 13. Green cover includes private backyards and frontyards, street boulevards, and public green space. Grey cover includes the building footrpints, roads, and large cement surfaces (i.e., parking lots).
Private lawns significantly contribute to the grey cover due to the dominance of low-density land uses
The majority of grey space is
attributed to the industrial area.
