Flood Information

Flood Protection Regulations

Every lot was originally designed so water would flow away from the building and along property lines to the street, storm sewer, or ditch. Fences, railroad ties, landscaping and regrading block this flow. So do construction projects in the ditches or the floodplain.
Always check with the Building Department before you build on, fill, alter, or regrade your property. A permit is needed to ensure that such projects do not cause problems on other properties.


Every piece of trash can contribute to flooding. Even grass clippings and branches can accumulate and plug channels. If your property is next to a ditch or storage basin, please do your part and keep the banks clear of brush and debris.
Do not dump or throw anything into the ditches or basins. Dumping in our ditches and storage basins is a violation of Village Code.
You can do your part in helping the drainage system work. Sweep or pick up your gutters to prevent blockages in the storm sewers. Pick up trash and fallen branches in the ditches.


New buildings in the floodplain must be protected from flood damage. Our building code requires that new residential buildings must be elevated one foot above the base flood level.


The ordinance also requires that all substantial improve­ments to a building be treated as a new building. A substantial improvement is when the value of an addition, alteration, repair or reconstruction project exceeds 50% of the value of the existing building.


If you see dumping or debris in the ditches or basins, filling or construction near property lot lines, or filling or construction in the floodplain without a permit sign posted, contact the Building Department at 708-895-7193. The debris or project may cause flooding on your property


In the case of an addition, only the addition must be protected. In the case of an improvement to the original building, the entire building must be protected. For example, if a house in the floodplain is flooded, has a fire, is hit by a tornado, or is otherwise damaged so that the cost of repairs is more than 50% of the value of the building before the damage, then the house must be elevated above the base flood level. These regulations are designed to protect you and your neighbors. By keeping the drainage system clear and getting the proper permits before you build, we can prevent flooding and other drainage problems.

Sammy's Safety Tipssammy sm
Look out for animals that have been flooded out of their homes and who may seek shelter in yours. Use a pole or stick to poke and turn things over and scare away small animals.
Look before you step. After a flood, the ground and floors are covered with debris including broken bottles and nails, Floors and stairs that have been covered with mud can be slippery.
Be alert for gas leaks. Use a flashlight to inspect for damage. Don't smoke or use candles, lanterns or open flames unless you know the gas has been turned off and the area has been ventilated.
