Do those individual polygons have any useful information on them
(addresses, for example)? If so, we should generate addr points from their
centroids.

Either way, we could save useful OSM information by creating a new polygon
from the outside edges of each block. basically, remove all overlapping
nodes except the ones on the outside. This way we maintain (semi-)useful
landuse information and remove the extremely noisy tax plat information
that's there already.
