Cook County TIF Boundaries Open Dataset
On April 8th Cook County GIS and the Cook County Clerk’s Office added Tax Increment Financing (TIF) District Boundaries to the Open Data Portal. The description states:
TIF District boundaries. TIF districts receive money from property taxes by utilizing increases in the value of properties located in the TIF. There is no tax rate for TIF districts. Instead, TIFs receive money based on tax rates generated by other districts’ tax levies. Money is allocated to the TIF based on the composite tax rate for properties in the TIF and the incremental value of properties in that TIF (when compared to values when the TIF was established.)
This release is a result of ongoing collaboration between Cook County GIS and the Cook County Clerk’s office as well as a dataset suggestion from the public. A Dataset Suggestion submitted on March 29th through the Socrata Data Portal Suggest a Dataset tool asked for “TIF shapes.” After consulting with the Clerk’s office the GIS Department added the TIF boundary data to the portal. TIF boundaries have been available for TIFs controlled by the City of Chicago for some time. Now, the data is available county-wide.
Dataset suggestions can be submitted through the nominate form at: https://datacatalog.cookcountyil.gov/nominate or by emailing . As part of my work on the Cook County Open Data project, I monitor the submissions to these places and help keep track of all requests.
