The biggest problem with this import is that it's impossible to download 
any reasonably-sized area of Fresno for editing, because of how the 
landuse polygons end at every street and alley. It's even worse in the 
suburbs where the streets curve, adding many nodes to each way.

(By the way, the word is cadastral, not castadral. And I see nothing 
wrong with using such data as part of a semi-manual process of creating 
larger landuse polygons for neighborhoods, and commercial strips 
surrounding highways. See Orlando, FL for a (mostly fully-manual) 
example of how this works.)
