Edwardsville sits on the bluffs above the American Bottom — the broad Mississippi floodplain stretching west of the city — which gives newcomers a false sense of security. The river may not reach your door, but the water still finds you. On August 12, 2019, severe flash flooding swept the Metro East, and the SBA approved a disaster declaration that October for Madison County homeowners, renters, and businesses. Three winters earlier, three days of torrential rain in December 2015 caused countywide flooding: more than 150 businesses and residences severely damaged, local government costs exceeding $10 million.
The city's real flood story is written in the lowlands below it. The Metro East levees protect some 130,000 people across the American Bottom, and the Great Flood of 1993 remains the defining disaster — when a levee breached near Columbia on August 1, 1993, Valmeyer went under as much as 16 feet of water, 90% of its structures were damaged beyond repair, and FEMA bought out the town, which relocated to the bluffs. The region is now upgrading toward 500-year flood protection — a $130M+ program of relief wells, cutoff walls, and seepage berms concentrated between Cahokia and Edwardsville. And on December 10, 2021, an EF3 tornado struck the Amazon warehouse in Edwardsville at 8:29 PM, collapsing the 1.1-million-square-foot facility and killing six workers — the same storm system that battered the whole Metro East with wind-driven rain.

Common Causes of Water Damage in Edwardsville
- Flash flooding, not river overtopping. Edwardsville's signature risk is intense summer downpours overwhelming the Cahokia Creek watershed and storm-drain systems — the August 2019 event that drew an SBA disaster declaration is the modern benchmark.
- The American Bottom lowlands. The city is mostly elevated, but surrounding bottomlands and creek corridors are the flood-prone zones; properties near the creek and lowland drainage paths take water first.
- The December 2021 EF3. The tornado that collapsed the Amazon facility was part of a late-season outbreak that killed more than 80 people across five states; wind-driven rain breached roofs and windows across the Metro East, creating water-damage losses far from the touchdown.
- Growth-phase drainage. Strong post-2000 growth means extensive newer subdivisions along the I-270/IL-255 belt and Route 159 corridor — where grading, construction-phase drainage, and new impervious surfaces redirect runoff onto neighboring properties.
- Bluff-side and rental-stock freeze risk. Older downtown-area homes with crawl spaces, uninsulated plumbing in bluff-side houses, and the SIUE-area rental stock — where students lower thermostats during winter breaks, a classic burst-pipe trigger — carry the January-2019-vortex freeze profile, and the rapid thaws that follow crack mains and supply lines.
Our Edwardsville Restoration Process
- Call (773) 200-3228 — 24/7. Flash floods get immediate dispatch; tell us if water is entering from a creek, a street, or inside the house.
- Trace the water's path. Creek overflow, storm-drain backup, roof breach, or burst supply line — in a flash-flood town, the entry point tells us the contamination level and the insurance story.
- Extract and contain. Standing water is pumped out fast; anything the flood touched is treated as contaminated until testing says otherwise.
- Metered drying for every structure type. From historic downtown framing to new-construction townhomes, air movers and dehumidifiers run against moisture-mapped targets until readings confirm dry.
- Sanitize and block mold. Contaminated surfaces are disinfected; compromised porous materials are removed before mold establishes.
- Document and rebuild. Repairs to pre-loss condition plus a complete photo and moisture-log file for your adjuster.

Cost Factors & Insurance Claim Help
No flat quotes — every Edwardsville loss is scoped on its facts: the water category (clean supply water versus flash-flood runoff or sewage), how much of the structure stayed wet and for how long, and the age and materials of the property. Edwardsville-specific factors: whether the loss came from the 2019-style flash flood (a flood-insurance question if stormwater, but often a covered homeowners peril when it enters through wind-damaged roofs), whether the property is a student rental where thermostat setbacks contributed to a freeze burst, and whether new-construction grading disputes are part of the claim. We photograph and log everything and work directly with your insurer from first call to final walkthrough.
Frequently Asked Questions
If Edwardsville sits on the bluffs, why does it flood?
Because the city's risk is flash flooding, not river overtopping. Edwardsville is mostly elevated above the American Bottom, but intense summer downpours overwhelm the Cahokia Creek watershed and storm-drain systems — the August 2019 event drew an SBA disaster declaration for Madison County. Being on the bluffs protects you from the Mississippi; it doesn't protect you from the creek, the street, or the sky.
What happened in the August 12, 2019 Metro East flash flood?
Severe flash flooding swept the Metro East on August 12, 2019, damaging homes, renters' properties, and businesses across Madison County. The SBA approved a disaster declaration that October, making low-interest loans available to affected homeowners, renters, and businesses. If you took water that day and never fully dried the structure, trapped moisture may still be damaging it.
How did the December 10, 2021 EF3 tornado affect buildings beyond the Amazon site?
The 8:29 PM EF3 collapsed the 1.1-million-square-foot Amazon warehouse, killing six workers, as part of a late-season outbreak that killed more than 80 people across five states. But the storm system's damage extended across the Metro East: wind-driven rain breached roofs, windows, and siding on homes and businesses miles from the touchdown, creating water-damage losses that show up as stains, swelling, and mold long after the debris was cleared.
What happened to Valmeyer in 1993, and what does it mean for the American Bottom?
During the Great Flood of 1993, a levee breached near Columbia on August 1, 1993, putting Valmeyer under as much as 16 feet of water; 90% of its homes and commercial structures were damaged beyond repair. FEMA bought out the homeowners and the town relocated to the bluffs. It's the American Bottom's defining lesson — and the reason the region is now investing $130M+ to upgrade its levees toward 500-year flood protection.
I rent near SIUE. What freeze risks should I know about?
Student rental stock has a well-known burst-pipe trigger: thermostats lowered or turned off during winter breaks, combined with uninsulated runs in crawl spaces or exterior walls. In a polar-vortex winter like January 2019's, that combination bursts pipes in empty houses. If you're leaving for break, keep the heat on, open cabinet doors under sinks on exterior walls, and know where the main shutoff is — or ask your landlord to confirm the heat stays up.
