Some flood problems get fixed. In Sycamore, one got a federal recommendation: move. A 1979 Army Corps report found Evergreen Village Mobile Home Park is a low-lying area flooded by both the Kishwaukee River and Tributary A in any 5-year storm or greater — and recommended relocating the park. The South Branch Kishwaukee has exceeded flood stage nine times since 1926. In July 1983 it hit 15.8 feet at DeKalb — flood stage is 10.0 feet — the highest level on record. After 4.85 inches of rain in August 2007, it rose to its highest since 1983 and second-highest on record: local emergencies declared, roughly 600 residents displaced, NIU's DeKalb campus shut down, and a Presidential disaster declaration — one of five in the watershed (1973, 1974, 1993, 1996, 2007).
A 1985 Illinois Pollution Control Board decision found the city's sanitary system suffered "inordinately high inflow and infiltration" — roof downspouts were ordered disconnected from the sanitary sewer — and a 1987 decision records a bypass from the north wastewater treatment plant to the Kishwaukee River installed in 1993, "used to relieve flooding and basement backups within Sycamore." The 1985 record even notes "live fish in the streets" as evidence of overbank flooding reaching manholes.

Common causes of water damage in Sycamore
- The South Branch Kishwaukee River. 15.8 feet at DeKalb in July 1983 (flood stage 10.0) — the highest on record — and the second-highest in August 2007. Federal disaster declarations for Kishwaukee flooding came in 1973, 1974, 1993, 1996, and 2007.
- A chronic flood zone at Evergreen Village. The Corps found the mobile home park floods from both the Kishwaukee River and Tributary A in any 5-year storm or greater — and recommended relocation. Low-lying river-adjacent property carries this risk by geography.
- Documented basement backups. Sycamore's sanitary system has a documented history of surcharging and backing sewage into basements — in the 1980s from inflow and infiltration, with a 1993 plant bypass built to relieve flooding and backups.
- Training thunderstorms and flash floods. Mid-to-late-summer flash flooding hits low-lying areas along the river in DeKalb County — as recently as September 2026, the NWS issued a Flood Advisory for southern DeKalb County, and a July 2022 Flood Watch explicitly included Sycamore.
- The East Branch watershed. The East Branch of the South Branch Kishwaukee meets the South Branch about one mile west of Sycamore; its 123-square-mile watershed drains into the South Branch at Sycamore, so storms across that basin arrive here.

Our Sycamore restoration process
- Call (773) 200-3228 any hour. River water, a sewer backup, or a clean supply-line failure each get a different first response.
- Classify the water. We identify the source and contamination level — overbank river water and sanitary backups get contamination protocols from the first minute.
- Remove the water. Pumps and extractors clear standing water while we protect the parts of your home the water hasn't reached.
- Dehumidify and verify. Air movers and dehumidifiers run against moisture-mapped targets, with daily readings until framing and walls test genuinely dry.
- Disinfect and stop mold. Flood- and sewage-contacted surfaces are disinfected; contaminated porous materials are removed so mold can't establish behind fresh paint.
- Put it back, and prove it. Damaged finishes are replaced to pre-loss condition, and every step is photographed and logged for your claim.
Frequently asked questions
Why does Evergreen Village flood so often?
A 1979 Army Corps report found the park floods from both the Kishwaukee River and Tributary A in any 5-year storm or greater — and recommended relocating it. It's the clearest illustration of how geography, not drainage design, drives Sycamore flood risk.
How high did the Kishwaukee River get in 1983?
15.8 feet at DeKalb — flood stage is 10.0 feet — the highest on record dating back to 1926. August 2007 brought the second-highest level, displacing roughly 600 residents across DeKalb and Sycamore.
What happened in Sycamore during the August 2007 flood?
After 4.85 inches of rain at DeKalb, the river rose to its highest since 1983. Local emergencies were declared; about 600 residents were displaced; NIU's campus shut down. The President declared a major disaster area — one of five federal declarations in the watershed (1973, 1974, 1993, 1996, 2007).
Were there really fish in Sycamore's streets?
Yes — the 1985 Illinois Pollution Control Board record cites "live fish in the streets" as proof that overbank flooding was reaching manholes and infiltrating the sanitary system, which is why roof downspouts were ordered disconnected from it.
Do Sycamore sewers still back up today?
The problems were addressed in stages — including the 1993 bypass to the river, installed "to relieve flooding and basement backups within Sycamore," and today's separate storm sewer system. But backups remain a known local risk; a backwater valve and a backup endorsement on your policy are smart precautions.
Cost factors & insurance claim help
We never quote by phone — every Sycamore loss is scoped on its facts. Cost turns on the water category (Kishwaukee floodwater and sanitary backups require the most extensive sanitation), how much of the structure stayed wet and for how long, and the age of the materials — Victorian plaster and historic woodwork extend drying time. Sanitary backups are typically covered only with a sewer/sump backup endorsement; river overbank flooding is a flood-insurance matter. Given Sycamore's documented backup history, the endorsement is the single most important line on a local policy. We photograph and log everything and work directly with your insurance company from first call to final walkthrough.
