Troy Grove is a small village in northern LaSalle County, set on the prairie between the Illinois River valley and the open farmland to the north. It lies away from the immediate riverbanks, so its flood risk is generally tied to local drainage. When a parcel falls within a FEMA Special Flood Hazard Area, an Elevation Certificate documents how a building relates to the Base Flood Elevation.
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.

The village of Troy Grove, home to roughly 225 residents in Troy Grove Township, sits on higher northern LaSalle County ground rather than a riverbank, so its flood concerns center on smaller creeks and drainageways rather than a major river. Where 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, giving insurers and the floodplain administrator the figures they need. A certificate showing the structure above the Base Flood Elevation can support a Letter of Map Amendment. Deeds for Troy Grove parcels are recorded through the LaSalle County Recorder of Deeds in Ottawa. Set well above the river valley, Troy Grove’s lots generally fall outside mapped flood areas.
Troy Grove sits on higher prairie ground away from the Illinois River, so its flood exposure is generally tied to local drainage rather than a major river.
The surveyor records the building’s measured elevations alongside the Base Flood Elevation so anyone reading the certificate can see how high the structure sits relative to expected flood levels.
It is generally required only when building or improving within a mapped Special Flood Hazard Area, where the floodplain administrator needs elevation data to approve the permit.
