Full Breakdown
Portions of Orland Park lie within FEMA-mapped floodplains, primarily along Tinley Creek, Marley Creek, and tributaries of the Cal-Sag Channel. Properties in Special Flood Hazard Areas (SFHAs, shown as Zones A or AE on the Flood Insurance Rate Map) are subject to floodplain development regulations under the Cook County Watershed Management Ordinance and Village-adopted floodplain rules. A floodplain development permit is required for any construction, substantial improvement, fill, grading, or storage in the SFHA. The lowest floor (including basement) of new or substantially improved residential structures must be elevated to at least 1 foot above the base flood elevation (Cook County requires 1 foot of freeboard).
Substantial improvement (work valued at 50% or more of the structure's market value) triggers full compliance for the entire structure. Flood insurance under the NFIP is required for federally-backed mortgages on properties in SFHAs. Compensatory storage is required for any fill placed in the floodway or flood fringe to ensure no rise in flood elevations. Floodway encroachments are particularly restricted. Property owners can verify their flood zone using the FEMA Flood Map Service Center or by contacting Village Public Works.
Violations & Fines
Unpermitted construction in the floodplain may result in stop-work orders, fines from $150 per day, and required removal of non-compliant work. Substantially damaged structures may not be rebuilt without elevation compliance. Failure to maintain flood insurance on a federally-backed mortgage in a SFHA can trigger lender force-placed insurance. Contact Public Works at (708) 403-6350.
