The Zoning District Maps (ZDM) are a series of maps that provide zoning boundary and code detail as well as a list of County Ordinances that affected the zoning contained on the particular map. The legend describes relevant elements found on all ZDM maps. A list of zoning designations can be found here. The ZDM page index lists the map number of each ZDM map and should be used to identify the map in your area of interest. Once you have found the needed map, find it in the related items below, or type ZDM xxx in the search bar above where xxx is the map number.
If you don't need the detailed notes and ordinances found on the PDF maps found here, you can also use MyNeighborhood and the "map overlays" widget to turn on a county-wide zoning layer.
