Flooding in Gurnee
The most dangerous flood hazard area in Gurnee is in the low lying area around the Des Plaines River and its tributaries. Flooding associated with the river threatens public safety and property and triggers the Village of Gurnee Emergency Operations Plan. If you have not checked the location of your home and its relationship to the flood hazard area on the flood insurance rate map (FIRM) please take the time to do so. If your property is shown to be in or close to a flood hazard area please feel free to contact the Village for guidance on how to protect yourself and your property.
Flooding limits shown on the Federal Insurance Rate Map (FIRM) are determined by estimating the elevation above sea level for a specific flood event such as the 1% flood (also called a 100 year flood). Structures built in the vicinity of flood hazard areas may have an elevation certificate prepared that measures the elevation above sea level of the structure for comparison against the floodplain elevation. The Engineering Division maintains copies of elevation certificates if they are provided by the property owner. Please contact the Engineering Division at 847.599.7550 to see if an elevation certificate is available for a specific property.
