Peoria County GIS: Peoria County GIS Map Rack

If you are not able to use the GIS websites found on the home page of the GIS Division, please try these maps in available for download PDF format. We have collected several maps that pertain to Peoria County and posted them here:

Please be aware, some of these maps are from external sources and may not have been updated for several years. 

In the past few months, we were able to work with the County Clerk's voter code and verify the county board boundary. This newly updated boundary is aligned with parcel boundaries. As a result the GIS Division recreated and updated Peoria County Board boundary maps and they are available below. They are on 11"x17" paper.

Our Summer Intern created these updated Tax Districts maps. We also sent our district boundaries to the Illinois Department of Revenue. This information will now be updated by the Supervisor of Assessments with aid from the County Clerk. These are the 2010 maps with 2009 tax information, being the last completed tax cycle.  

In preparation for the 2010 census results, the Illinois State Library needed updated maps for all the libraries in Peoria County. We created and sent these maps to the State along with providing them to you.

These were made for the County Clerk's Office in 2001-2002 by Tri-County Regional Planning Commission. The next planed update will be after the 2010 decennial census.
