Excerpts from nbcchicago.com:
Lyons Fire Chief Gordon Nord said Monday that firefighters evacuated about 40 people and their pets via boats from homes Sunday night as heavy rainfall brought flooding to the area where the water level was higher than chest deep on some streets. The current was moving as the water flooded into the area from the nearby Salt Creek.
It may be a few days before the water recedes enough to allow people back inside their homes. Not everyone in the areas most impacted left their homes, but those who chose to stay can now only leave if it’s an emergency. In that case, firefighters would bring boats back to the area to assist in the evacuation.
