When Spring Rains Turn Your Home Into a Flood Zone: The Hidden Crisis in Cook County’s Drainage Systems

Spring in Cook County brings more than just blooming flowers and warmer weather—it brings a seasonal threat that homeowners across the region know all too well. The state’s climate has gotten wetter in the springtime, which combined with rapid snowmelt and heavier rainfall means rivers in Illinois are often breaking records for highest peaks, and winter and spring are expected to be wetter in Illinois while summer becomes even hotter. This changing weather pattern is creating unprecedented challenges for residential drainage systems throughout the county.

The Perfect Storm: Why Spring Flooding Has Become the New Normal

More than 200,000 Cook County properties are at major or severe risk of flooding in the next 30 years, according to data released by the First Street Foundation. The problem isn’t just about properties near rivers or lakes—a lot of those properties at risk are nowhere near a river, lake or designated flood zone, with aging sewage or drainage systems not equipped to handle the high volume of rain falling in a short period of time, causing pluvial or surface flooding caused by overwhelmed drainage systems.

The infrastructure challenge is particularly acute in Cook County, where an estimated 42% of Cook County is impervious surface, meaning water from Chicago’s recent record-breaking storms cannot be absorbed, as we have removed the natural absorptive capacity of our landscape giving the rainwater nowhere to go. This urbanization has created a dangerous situation where the sewer system gets overwhelmed after just two-thirds of an inch of rainfall in an hour, according to modeling by the Metropolitan Water Reclamation District (MWRD).

Understanding the Anatomy of Spring Drainage Disasters

Spring flooding in Cook County typically manifests in several ways that directly impact residential drainage systems. Some common types of flooding include flooding from runoff that exceeds the capacity of the sewer system and basement backups from flow that exceeds the capacity of the sewer system. During heavy spring rains, excess water can cause the sewers to “surcharge,” and push water backward through home sewer laterals and cause sewage to backup into the home through basement floor drains, toilets and sinks.

The problem is compounded by Chicago’s aging infrastructure. During heavy rains, Chicago’s 100 year old combined sewer system may reach capacity resulting in backup. In these combined systems, sanitary sewage and stormwater drain into the same pipes. When spring storms overwhelm this system, the results can be devastating for homeowners.

The Human Cost of Overwhelmed Drainage Systems

Historic rain that pelted Cook County left residents standing in basements with dirty water wading up to their knees, discovering black mold scattered throughout basements, having to replace water heaters, with the July 2023 storm being one of the costliest weather events in Chicago’s history. These aren’t isolated incidents—they’re becoming the new reality for thousands of Cook County residents each spring.

The financial impact extends far beyond immediate cleanup costs. In the wake of major storms, FEMA has inspected 63,000 homes, and distributed up to $375 million in federal aid to home and business owners. However, of those properties at risk, 94% are uninsured.

Preventive Measures and Long-term Solutions

While professional intervention is often necessary during spring flooding events, homeowners can take steps to minimize their vulnerability. Having check valves installed in building sewer traps can prevent flood waters from backing up in sewer drains. Additionally, disconnecting downspouts from the drainage system is crucial, as a house with a roof that is 800 square feet can send about 500 gallons of water to the sewer during a one-inch storm, and when the system gets overwhelmed, all of that water can come right back into your home.

Regular maintenance is also critical. The privately owned sewer pipes that run from your home to the main under the street can cause problems if there are tree roots, grease, or other blockages obstructing the pipe, or if cracks or connections are letting in additional water and causing them to exceed capacity, making periodic private inspections from a certified plumber essential to identify and resolve any issues.

Looking Ahead: Climate Change and Future Challenges

The challenges facing Cook County’s drainage systems are only expected to intensify. Climate change will only exacerbate flooding across the County, especially in communities with historic disinvestment which were disproportionately impacted by COVID-19. Cook County has about 172,000 properties at substantial risk for flooding, and this group is projected to grow by about 10% by 2053.

Recognizing the severity of the situation, Cook County Board President Toni Preckwinkle announced $20 million in funding for the Stormwater Management Project Implementation Program, with funding provided through the American Rescue Plan Act (ARPA) to advance 26 stormwater management projects throughout the County, with a focus on supporting under-resourced communities.
