This year, concurrent with the new census results, the Lake County Board district map is being redrawn, just like all of the other government districts. The primary change is that the Board is proposing that the number of districts be reduced from 23 to 21.
The new proposed map can be viewed at the Lake County website, but getting to it is a bit of a pain.
First, click here, and then click at the upper right-hand corner to view the reapportionment committee hearing agenda (set for Tuesday, June 7th at 2:00 pm), and then open up the meeting agenda PDF. Then click on the embedded hyperlink to view the "Proposed Map" (page 2, section 7.1 of the agenda).
You can expect some gnashing of teeth by the Dems since the GOP essentially got to draw this map, but compared to the closed process the Dems used to draw the state and congressional district maps, they have essentially left themselves no room to complain about whatever the GOP did. It's a fair map, nevertheless.
UPDATED: Russell Lissau at the Daily Herald has a good article up with reaction from several county board members; four Democrats will find themselves doubled up into two districts.
