Sprinkling restrictions, which go into effect May 15 until September 15 of each calendar year, prohibit sprinkler use between the hours of 12:00 PM to 6:00 PM and limit lawn irrigation only on odd/even days that correspond with the property's address. Addresses that end in an even number (0,2,4,6,8) are allowed to water outside on calendar days that are even. Addresses that end in an odd number (1,3,5,7,9) are allowed to water outside on calendar days that are odd.
Exceptions include the use of hand-held hoses or sprinkling cans for watering shrubs or gardens. This ordinance was passed in 1990 following a request by the Illinois Division of Water Resources to conserve Lake Michigan Water.
