Water Damage Restoration in Mount Prospect, IL

September 1986 is the flood every other Mount Prospect flood gets measured against. The Des Plaines River hit its highest recorded level: roughly $35 million in damages, 10,000 dwellings and 263 business and industrial sites, more than 15,000 residents evacuated, seven deaths — across 33 municipalities and 67 miles of river. The 1986 and 1987 floods triggered the project that now defines the village's defenses: Levee 37. Congress funded it in 1999, the Metropolitan Water Reclamation District built it, and it was completed in 2015 — protecting more than 600 homes and dozens of businesses from 100-year riverine flooding, avoiding an estimated $3 million a year in damages.

But levees only fight the river. In April 2013, 5.5 inches of rain fell in 24 hours — about a 25-year storm — while the Des Plaines was already rising. Inside Levee 37, the interior storm sewer system has less than one year of drainage protection when river tailwater is high: rain landing behind the levee ponds in basements and streets with nowhere to go. And part of the village still runs on a combined sewer system, with permitted overflow outfalls into Weller Creek and Feehanville Ditch.

Common causes of water damage in Mount Prospect

• The Des Plaines River. The northeast portion of the village (about 57,000 residents across 11 square miles) lies along the river and in its floodplain. September 1986 was the flood of record; 1987 brought 3–9 inches of rain, about $77.6 million in damages, and 3,000 homes damaged in Cook and DuPage Counties; July 1996 dropped 16-plus inches across the region.
• Interior drainage behind the levee. When the Des Plaines runs high, tailwater blocks the interior storm sewers — less than 1-year drainage protection inside. April 2013 (5.5 inches in 24 hours) is the textbook case: the river wasn't the problem; rain with nowhere to drain was.
• A partial combined sewer system. Illinois EPA NPDES Permit IL0052400 authorizes six CSO outfalls (001–006) into Weller Creek and Feehanville Ditch. The village's 2015 Combined Sewer Study, its mid-1990s downspout-disconnection program, and large 1980s relief sewers in the southern third all target the same issue: combined-system capacity in heavy rain.
• The O'Hare Reservoir context. The Chicago Underflow Plan's O'Hare Reservoir — which involved relocating Higgins Creek — was designed in part to relieve sewer backup flooding in portions of Mount Prospect, Des Plaines, and Arlington Heights: a decades-old engineering admission of the village's sewer-backup risk.
• Mid-century homes with mature trees. Mostly built out mid-century — brick ranches, Cape Cods, split-levels on quarter-acre lots under mature oaks and maples. Older plumbing, settled foundations, and root intrusion into laterals cause many sudden basement floods.
• McDonald Creek and local flash points. A retention wall along McDonald Creek sits adjacent to Levee 37, and the small-tributary corridor is an active local concern — these creeks surge long before the river rises.

Cost factors & insurance claim help in Mount Prospect

No flat quotes — every Mount Prospect loss is scoped on its facts: the water category (river floodwater, stormwater, combined-sewer backup, or clean supply water), how much of the structure stayed wet and for how long, and the home's age and materials. The category question matters more than most places: combined-sewer areas may need a sewer backup endorsement, while Des Plaines River overbank flooding is a flood-insurance matter — and April-2013-style interior ponding can land on either side depending on the source. We sort that out with you before work begins, document everything, and work directly with your insurance company from first call to final walkthrough.
