Cook County’s Changing Flood Landscape Puts Previously Safe Neighborhoods at Risk in 2025
Cook County residents are facing an unprecedented shift in flood risk patterns that’s catching many homeowners off guard. Pending products, to be effective 1/23/2026, are available from FEMA, indicating significant updates to flood zone designations that will impact thousands of properties across the region. What’s particularly alarming is that more than 200,000 Cook County properties are at major or severe risk of flooding in the next 30 years, with 94% are uninsured.
Why Previously Safe Areas Are Now at Risk
The transformation of Cook County’s flood risk landscape stems from several converging factors that have fundamentally altered how water moves through our communities. An estimated 42% of Cook County is impervious surface, meaning water from Chicago’s recent record-breaking storms cannot be absorbed. This dramatic increase in hard surfaces like driveways, parking lots, and streets has eliminated the natural capacity for rainwater to soak into the ground.
A lot of those properties at risk are nowhere near a river, lake or designated flood zone, which represents a significant departure from traditional flood risk patterns. The culprit is what experts call pluvial or surface flooding, caused by overwhelmed and aging sewage or drainage systems, not equipped to handle the high volume of rain falling in a short period of time.
Recent Flooding Events Signal Growing Threat
Cook County has experienced multiple severe flooding events in 2025 that underscore the urgency of this changing risk profile. City of Chicago Mayor Brandon Johnson and Cook County Board President Toni Preckwinkle are issuing respective disaster proclamations to assist residents in recovering from flooding that took place July 25-28. The City and Cook County experienced significant rainfall over several days, leading to flooding in residential areas.
The scale of damage has been substantial, with City of Chicago, Burbank, Justice and Summit were among the hardest hit Cook County municipalities. These events prompted state and federal disaster declarations, highlighting the severity of the flooding impact on communities that may never have experienced such risks before.
The Critical Role of Sump Pumps in Modern Flood Protection
As flood zones expand and traditional drainage systems struggle to cope, sump pumps have become essential protection for Cook County homeowners. A sump pump can be your first line of defense against flooding. You can install it in your basement or crawl space, so as to pump water out of your house or property. Even though the initial installation can be pricey, the price you pay for it is nothing compared to the protection it will give you.
