Respite care, residential facilities or day programs for people with developmental disabilities are possibilities if a local 377 board is approved, proponents say.

McHenry County would join 14 Illinois counties that have a 377 board to benefit people with developmental disabilities if voters approve a referendum on the April 9 election ballot.

It will ask whether the county should establish a 377 board and create a tax levy that would add 10 cents per $100 of assessed valuation to county property taxpayers’ bills. That rate would mean an increase of about $60 a year for the owner of a $200,000 home who takes the homestead exemption.
