Somonauk is a village at the southern edge of DeKalb County, with a portion extending into LaSalle County and named-for-it Somonauk Creek running nearby. Creek- and low-lying parcels can be mapped into a FEMA Special Flood Hazard Area, while higher ground carries limited exposure. A FEMA Elevation Certificate records a building’s elevation against the Base Flood Elevation for insurance and permitting.
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.

Somonauk has a population of about 1,786, primarily in Somonauk Township in southern DeKalb County, with part of the community extending into LaSalle County. The village is not centered on a major river, so its FEMA Special Flood Hazard Areas generally follow local creek drainage and low ground rather than a broad corridor. Where a parcel falls inside a mapped flood zone, a licensed surveyor prepares the Elevation Certificate by measuring the lowest floor and grade against the Base Flood Elevation, which insurers use to rate policies and the county uses to review floodplain permits. If a structure is documented above the flood level, the certificate can support a Letter of Map Amendment. For the DeKalb County portion of Somonauk, survey documents are recorded with the DeKalb County Clerk & Recorder in Sycamore.
For the DeKalb County part of Somonauk, records go to the DeKalb County Clerk & Recorder in Sycamore. Parcels within the LaSalle County portion are recorded in LaSalle County.
