What is the Diamond Bar Zoning Map, and how can I see a copy?

The Diamond Bar Zoning Map designates existing land use classifications for each parcel located within the city. In addition to land use types (residential, commercial, and open space/conservation), the map also indicates the density of housing development allowed such as Low Medium Density Residential (RLM), Medium High Density Residential (RMH), and High Density Residential (RH). The Zoning Map is available online as part of the City’s GIS mapping database. To view the Zoning Map, click the Layers List icon on the top right corner and select “Zoning.” For more information, contact the Planning Division at (909) 839-7030 or planning@diamondbarca.gov.
