Full Breakdown
Schaumburg's flood risk is primarily associated with Salt Creek, which flows through the Village and has historically caused significant flooding. FEMA Flood Insurance Rate Maps (FIRMs) identify Special Flood Hazard Areas (zones AE, A, AH) along Salt Creek and its tributaries. The Village enforces its floodplain management ordinance in compliance with NFIP requirements and the Cook County Watershed Management Ordinance. New construction in the SFHA must elevate the lowest floor (including basement) at least one foot above the base flood elevation (BFE) as shown on the FIRM.
Some areas may require two feet above BFE per local requirements. Substantial improvements (exceeding 50% of the structure's market value) to existing buildings in the floodplain must also meet elevation requirements. Basements are restricted in the floodplain; below-BFE enclosed areas must be used only for parking, access, or storage and must have flood openings to equalize hydrostatic pressure. Fill in the floodway is prohibited. All development in the SFHA requires a floodplain development permit from the Village. Flood insurance is mandatory for properties with federally-backed mortgages in the SFHA.
The Village may participate in the Community Rating System, which can reduce flood insurance premiums for policyholders. Properties outside the SFHA may still experience localized flooding from overland flow and should consider voluntary flood insurance.
Violations & Fines
Building in the floodplain without a floodplain development permit is a serious violation. Non-compliant construction may be required to be elevated, modified, or removed. Fill placed in the floodway without authorization violates federal, county, and local regulations. Failure to maintain required flood openings in below-BFE enclosures is a violation. The Village may report violations to FEMA, potentially affecting community-wide NFIP standing.
