Full Text of Legislation:

WHEREAS, the Clerk of Cook County maintains the Cook County permanent real estate index numbering system maps (“ Tax Maps”) representing all parcels in Cook County for the purposes of real estate taxation; and,


WHEREAS, these Tax Maps, previously maintained on mylar transparencies, are now being updated and maintained by County Clerk staff in a computerized format, through the tools provided by the County Geographic Information System; and


WHEREAS, the County Board in Ordinance 91-O-59 provided for a fee for photographing the mylars so that they could be made available to the public and commercial users interested in copying the mylars; and


WHEREAS, the mylars are being replaced by an imaged set of Tax Maps, which contain exactly the same information previously available to commercial users in the form of the mylar transparencies; and


WHEREAS, the imaged County Tax Maps are a “read-only” picture of the County Tax Maps in a digital format and do not represent the fully accessible Geographic Information System still under development by the County; and


WHEREAS, the Cook County Board of Commissions desires to establish fair and reasonable access to the complete set of Tax Maps in an imaged “read-only” digital format for commercial users who no longer will have access to the mylars; and


WHEREAS, the County asserts copyright protection for the Imaged Cook County Tax Maps.
