If I knew the Rockingham County GIS had such a helpful ZONING layer, I forgot about it temporarily.  Thanks for the reminder, Todd Rhea.

When you're in the GIS, just go to "Map Layers" (tab at the top) and then "Zoning and Districts" (group on the left) and then turn on "Zoning".

This can be helpful for you to examine when considering the purchase of a home out in the County (what is the land surrounding this property zoned?) or if you are considering the purchase of land or development purposes.
