As this figure shows, for most blocks, a pedestrian can walk from a corner across the street to a corner of the neighboring building.

For example, to go from (1,0) to (2,0), go to the northeast corner of (1,0), cross to (1,1), then go diagonally to the southeast corner of (1,1), and then cross the plowed street to the northeast corner of (2,1).
