Chicago’s spring and summer weather can rapidly transform from picturesque lakefront days to destructive storm events. With the city’s unique geography, aging infrastructure, and distinct building styles, Chicagoland property owners face specialized challenges that require tailored preparation strategies.
Recent events highlight the urgency of proper preparation, with the July 2023 storm causing unprecedented damage across the city’s West Side and nearby suburbs. This catastrophic event resulted in FEMA inspecting over 63,000 homes and distributing approximately $375 million in federal aid to affected property owners.
At Chicago Water & Fire Restoration, we’ve helped thousands of property owners recover from these devastating events. Here’s your essential guide to the five most common severe weather threats specific to Chicago properties during storm season and how to protect against them before disaster strikes.
5 storm risks unique to Chicago and how to prepare your home for them.
1. Basement Flooding from Chicago’s Aging Infrastructure
Chicago’s sewer system was designed decades ago when storm patterns were very different. Today’s climate brings a new kind of storm to Chicago with heavy rains that can be very localized, intense, and hard to predict—often dumping two inches or more hourly on specific neighborhoods (City of Chicago). This overwhelms our aging infrastructure, causing widespread basement flooding.
Chicago-Specific Protection Tips:
- Install a sump pump with battery backup specifically designed for Chicago’s clay soil conditions
- Consider check valves on all basement drains to prevent sewage backflow during heavy storms
- Disconnect downspouts from the sewer system, a practice once required by Chicago code but now discouraged
- For vintage Chicago bungalows and greystones, create proper grading around your foundation that accounts for settling common in older Chicago properties
- Install water leak detectors in multiple basement locations, particularly near Chicago’s notoriously problematic foundation walls
2. Lake Michigan-Induced Storm Damage
Chicago’s proximity to Lake Michigan creates unique weather patterns that can intensify spring and summer storms. Lake-effect precipitation, sudden wind shifts, and intense storm bands often catch property owners unprepared. During severe storms, the lake can even experience seiches—rapid water level rises resembling miniature tsunamis that can raise water levels 1.5-2.5 feet along Chicago’s shoreline (CBS Chicago).
Chicago-Specific Protection Tips:
- For lakefront properties, install impact-resistant windows rated for Chicago’s unique wind patterns
- Secure outdoor fixtures with hardware specifically designed for structures facing Lake Michigan
- For properties within three miles of the lake, consider specialized roof bracing to counter lake-effect wind uplift
- Install custom storm shutters designed for Chicago’s historic buildings that won’t detract from architectural integrity
- Apply lakefront-specific sealants around windows and doors that can withstand humidity, UV exposure, and temperature fluctuations
3. Flash Flooding in Chicago’s Urban Environment
Chicago’s high percentage of impermeable surfaces, combined with its relatively flat topography, creates ideal conditions for flash flooding during summer storms. The city ranks second in the country for the greatest number of properties at risk of flooding, according to the First Street Foundation (Chicago Fed Insights). Low-lying neighborhoods like Albany Park, Jefferson Park, and portions of the South Side are particularly vulnerable.
Chicago-Specific Protection Tips:
- Install flood barriers designed for Chicago’s common entry points (gangways, garden apartments, English basements)
- Consider rain gardens that work with Chicago’s native plant species and clay soil conditions
- For Chicago’s vintage multi-unit buildings, create water diversion systems that protect both your property and your neighbors’
- Elevate HVAC systems, water heaters, and electrical panels above Chicago’s documented flood levels for your neighborhood
- Install backwater valves specifically designed for Chicago’s combined sewer system
4. Wind Damage from Chicago’s Powerful Summer Storms
Chicago isn’t called the Windy City without reason. The city’s grid street pattern creates wind tunnels that intensify already strong gusts during severe thunderstorms. Recent summer storms have produced hurricane-force wind gusts exceeding 75 mph, with unofficial measurements as high as 80 mph in nearby suburbs (Fox Weather). These extreme winds can cause significant damage to roofs, siding, and trees throughout the metro area.
Chicago-Specific Protection Tips:
- Reinforce entry doors with Chicago-appropriate weatherstripping that can withstand extreme temperature fluctuations
- Install wind deflectors on downspouts to prevent wind uplift common to Chicago’s flat-roofed buildings
- Secure fencing with deeper post installations than national standards to account for Chicago’s soil conditions
- For Chicago two- and three-flats, install gable-end bracing to prevent structural shifting during microburst events
- Schedule professional tree maintenance before storm season to identify and remove hazardous limbs near your property
5. Power Outages from Chicago’s Vulnerable Electrical Grid
Chicago’s electrical infrastructure, while undergoing modernization, remains vulnerable during severe spring and summer storms. A single severe storm system can leave tens of thousands of ComEd customers without power, with outage numbers sometimes exceeding 24,000 in a single event (AP News). These outages can persist for days, particularly in older neighborhoods with above-ground electrical infrastructure.
Chicago-Specific Protection Tips:
- Install surge protectors designed for Chicago’s older electrical systems
- Consider a backup generator system that complies with Chicago’s strict building and fire codes
- Create an emergency lighting plan that accounts for Chicago’s lengthy power restoration times during major events
- For multi-unit buildings, invest in common area emergency systems that meet Chicago’s specific occupancy requirements
- Maintain a Chicago-appropriate emergency kit with items suitable for the city’s unique urban environment
Understanding Your Insurance Coverage for Chicago Storm Damage
Navigating insurance after storm damage can be challenging, especially with Chicago’s unique property types and weather patterns. Most standard homeowners policies cover wind damage, lightning strikes, and water damage from rain entering through storm-created openings. However, many Chicago residents are surprised to learn that standard policies typically exclude:
- Sewer backup coverage (a major issue in Chicago’s combined sewer system)
- Flood damage from rising waters or ground saturation
- Gradual water damage from long-term leaks
- Mold remediation beyond a minimal amount
For comprehensive protection in Chicago’s unique environment, consider these insurance enhancements:
- Water backup coverage specifically addressing Chicago’s sewer system challenges
- Flood insurance through the National Flood Insurance Program, especially important for properties in Chicago’s flood-prone areas
- Increased dwelling coverage that accounts for Chicago’s higher rebuilding costs
- Ordinance and law coverage to address Chicago’s strict building codes during restoration
