 (from Ch. 34, par. 5-1109)Sec. 5-1109.         Assessment maps in counties of less than  1,000,000.  The county board of any county having a population of less  than 1,000,000 inhabitants may whenever in the opinion of the board it  becomes necessary, retain the services of a surveyor who shall be  registered under the provisions of the Illinois Professional Land Surveyor  Act of 1989, as amended, or a person experienced in the  preparation of assessment maps or plats, to prepare assessment maps or  plats of all or any part of the real property in any or all of the  townships in such county.  Such maps shall show each separately assessed  parcel of real estate together with the area thereof. Subdivided  property in recorded plats shall be given the same designation as is  contained in the plat recorded, except that the surveyor may designate  by letter or number any assessed parcel within such recorded plat which  cannot be identified without describing it by metes and bounds.  Assessed  parcels not within recorded plats shall be designated by lot numbers or  letters.  The county board in each county may make such further  regulations concerning this work as are deemed necessary.  A copy of the  books containing such maps or plats shall be filed with the county  assessor or supervisor of assessments, with the recorder and  with the county clerk, and a copy of the maps or plats for each township  shall be filed with the assessor of such township, all of whom shall  maintain and preserve these copies subject to the provisions of the  Local Records Act, as amended. Upon the filing of the books as aforesaid,  the county clerk, the township or county assessor, the supervisor of  assessments, the board of review, and all other persons whose duty it is to  assess property within the area covered by the maps, shall, beginning with  the next quadrennial assessment year as set forth in Section 9-95 of the  Property Tax Code, assess the  parcels of land by identifying them in accordance with the description and  designation set forth in such assessment map or maps.  All maps filed in  accordance herewith shall be designated as "Supervisors' Assessment Maps ....  Township".In any county adopting the provisions of this Section, a surveyor,  who shall be registered under the provisions of the Illinois  Professional Land Surveyor Act of 1989, as amended, or a person  experienced in the preparation of assessment maps or plats, shall be  retained by the county board and shall prepare supplemental or  correction maps showing all changes in assessment descriptions made  subsequent to the preceding maps and prior to November 15 of the year  preceding each quadrennial assessment year.  Supplemental or correction  maps shall be prepared only of those pages upon which corrections or  changes are to be made and shall conform to the original maps filed  except as to such changes.  Copies of such supplemental or correction  maps or pages, properly indexed and identified, shall be bound in one  volume, if practical; shall be filed in the same manner as is herein  provided for copies of the original maps; and shall be known as  "Supplemental Supervisors' Assessment Maps for the year (insert year)".The expense of making such maps or plats and copies thereof shall be  borne by the county.
