No, there is no address information. The only "real" OSM tag on these
plot borders is landuse=residential. All the other tags are either
redundant geometric information (area, width, depth) or internal
Fresno GIS values.
Example:
http://www.openstreetmap.org/browse/way/61552301

Which is why they are useless. I would call this importing for the
renderer. We don't really want the map *tiles* to "bloom" we want the
map *data* to bloom and then the tiles can reflect this. This land
parcel information does the former but not the latter.

In the area I was just browsing, the landuse=commercial areas *might*
be worth leaving since they aren't as prolific and do convey at least
some useful information.
