The five council districts in the City of Peoria are going to change. After each decennial census, cities are required by law to redraw their district boundaries so that each district has an approximately equal number of residents. The process for redrawing those boundaries got started Thursday night in City Council chambers.

The City’s redistricting committee is made up of the five district council members: Clyde Gulley, Barbara Van Auken, Tim Riggenbach, Bill Spears, and Dan Irving, with Spears acting as chairman since he’s the longest serving of the five. Their first meeting lasted about an hour and consisted primarily of establishing the criteria for redrawing the district map. Some of the criteria are required by law (each district must have nearly equal population and be compact and contiguous), and other criteria were added by committee members (don’t split neighborhoods between multiple districts, use major thoroughfares as boundaries as much as possible).

Keeping these criteria in mind, the committee asked the staff to come back with some proposed maps for the next meeting. They’d like to see several different possible configurations: one that has all districts running east to west (layered), one that has all districts running north to south (columnar), one that has districts one through four laid out as quadrants with the fifth district across the top of it, and one that preserves the current districts as much as possible (West Bluff in second district, East Bluff in third district, valley in first district, etc.).

Senior urban planner Josh Naven is in charge of creating these map proposals. Unlike the old days when these maps had to be created by hand, Naven will have the use of ESRI Districting software. The software comes preloaded with political maps and all the 2010 Census data down to the block level, and has some interoperability with the County’s GIS system. When Naven draws a district boundary, the software will tell him the total population count, minority population, voting age, etc., within that boundary. He can use this information to ensure the new boundaries meet federal and state requirements as he draws the maps to the committee’s specifications.

All redistricting info is being posted to the City’s website at http://www.ci.peoria.il.us/redistricting. This is where the proposed maps will be posted within the week before the committee’s next meeting, which will be Tuesday, June 21, at 5:30 in City Council chambers.

While the committee doesn’t legally have to complete its work until nearly the end of 2012, the City’s Election Commission would like to see the new maps adopted by Labor Day of this year, if possible. Executive Director Tom Bride said the Commission has to redraw all the precincts in the City and send out new voter registration cards, and the council district boundaries impact this process. Precincts cannot be split across district boundary lines, and voting districts are printed on the voter registration cards. The Election Commission’s deadline for completing these tasks is earlier than the City’s deadline for establishing new district boundaries. Establishing the new district boundaries early will keep the Election Commission from having to redo its work later next year.
