Message from the Mayor...

Hello and welcome to Seneca!

Seneca has a variety of amenities to offer when considering to locate here.  The Village is approximately one hour from downtown Chicago or both Chicago O'Hare and Midway airports.  The Seneca I80 interchange, exit 105 was updated recently to accomodate transportation needs.  Interstate 80 is a few minutes from Seneca, and Seneca is approximately 32 miles from Interstate 39 and 21 miles from the I55 interchange.  Currently, plans are to create additional through travel lanes on US Route 6 and major intersection improvements.  As you can see from the industry listed below, Seneca is a development friendly community that offers rail to river transfer.  When working with developers, Village officials consider project needs, and realize that each project has different facets.


Jeff Olson, Mayor



TIF 1 and TIF 2 were designated in 2003 under the authority of the Industrial Jobs Recovery Law (IJRL) based upon the Village's higher unemployment rate (at the time).  The IJRL TIFs are in place for a maximum term of 23 years and similar to other TIF districts capture the growth in taxes resulting from increased development or value in the TIF.  Only industrial and related commercial development is allowed under the TIF plan (no residential).  One redevelopment agreement was approved early on, but the status is now under review.  TIF revenues are shared between the Village and the one project.
