HomeServicesFEMA Elevation Certificates › Onarga, IL

Onarga sits in central Iroquois County on the prairie farmland, set away from the Iroquois River that drives flooding on the county’s eastern side. Its flood exposure is generally modest and connected to local drainage. Where a parcel falls within a FEMA Special Flood Hazard Area, an Elevation Certificate documents how a building relates to the Base Flood Elevation.

What a FEMA Elevation Certificate shows

A FEMA Elevation Certificate documents your building’s elevation relative to the Base Flood Elevation on the FEMA flood map. Insurers use it to rate flood policies and communities use it to confirm floodplain compliance; it can also support a Letter of Map Amendment (LOMA) to remove a structure from a flood zone.

Onarga & Iroquois County specifics

The village of Onarga, home to about 1,333 residents in Onarga Township, occupies central Iroquois County farmland rather than the Iroquois River bottomland, so its flood concerns center on smaller drainageways. When a parcel is mapped into a Special Flood Hazard Area, a FEMA Elevation Certificate from a licensed Illinois surveyor records the lowest floor against the Base Flood Elevation, which insurers use for rating and the floodplain administrator uses for permit review. A certificate showing the structure above the Base Flood Elevation can support a Letter of Map Amendment. Deeds for Onarga parcels are recorded by the Iroquois County Recorder of Deeds at the county seat in Watseka. Set on central-county farmland, Onarga sees flood mapping only near its scattered drainageways.
