We are developing a GIS-based buildout analysis for our NJ county. (No, we are not entirely paved over.) We have a good handle on how to calculate residential build-out based on zoning, but non-residential is a real headache. Our county is completely incorporated with 39 municipalities and 39 zoning ordinances. (The County Planning Board has no zoning authority.) We are hoping to calculate build-out by municipality as well as for the county overall.
FYI - we have digitzied every single lot in the county and have over 50% of the zoning maps digitized. So we can calculate build-out parcel by parcel.
I hope the brilliant planners out there can help. Thanks
