We locate your parcel on the governing FEMA Flood Insurance Rate Map to identify flood zones.
The determination reports the flood zone and, where mapped, the Base Flood Elevation.
Surveyed structure and grade elevations are compared against the mapped floodplain boundary.
Findings can support a Letter of Map Amendment request when the structure sits above the floodplain.
The determination shows where the structure or parcel sits relative to FEMA’s mapped flood zones and the Special Flood Hazard Area boundary.
The survey data can support a request for a FEMA Letter of Map Amendment or Revision when a property appears to be mapped in error.
Owners, lenders, and insurers gain a clearer picture of a property’s mapped flood status to guide next steps.
The work is performed and certified by an Illinois-licensed professional land surveyor using the effective FEMA flood mapping.

A flood hazard determination focuses on where the structure or parcel falls relative to the mapped flood zone. An Elevation Certificate documents specific building elevations on FEMA’s standard form. The two are often used together when addressing flood-zone questions.
The survey provides the elevation and location data FEMA reviews for a Letter of Map Amendment or Revision. Whether a property is removed from the Special Flood Hazard Area is decided by FEMA, not the surveyor, based on that data and its criteria.
Federally regulated lenders generally require flood insurance for structures in a Special Flood Hazard Area. A surveyed determination can confirm or clarify the mapped status that drives that requirement.
