I ran across this being listed as strategic demolitions solid blue being actual structures and shaded being target areas. Not counting the structures are the shaded areas already empty? It kinda seems as though a few large blocks are outlined as being repurposed most noticeably at the intersection between Hamtrack and Highland park.

Not sure how to put it here and be able to zoom in.
