| Abstract |
The Planning Department conducted a comprehensive land use inventory of all land within the City of Ann Arbor's ultimate corporate boundary. This inventory includes parcels currently in Ann Arbor, Pittsfield, and ScioTownships which will be annexed into the City consistent with utility service agreements signed by the townships. The resulting GIS data layer combines the descriptive land use and administrative ownership data providing a valuable tool to assist the City of Ann Arbor with future land use planning decisions. |

During the Summer of 1998, data was collected through a visual survey of all parcels, using digital orthophotos overlaid with parcel maps as a guide. Parcels were assigned one of 46 land use codes and one of 3 administrative ownership codes. Additional information from the City Assessor's office and the City Housing Bureau was used to help identify administrative ownership and distinguish various residential land uses.
