A map zone is not a promise of zero risk
FEMA distinguishes mapped flood-hazard zones and explains that areas shown outside higher-hazard zones can still flood. Shaded and unshaded Zone X describe different mapping categories. A simple label should retain the source legend and map context rather than being translated into ‘safe’ or ‘no flooding.’

The chosen location can change a screen
Cook County Records screens a parcel location against the available flood-hazard layer. A centroid is one point representing a parcel; it is not the building footprint, floor elevation or the entire parcel boundary. A boundary crossing part of a site can be missed by a point screen.
The site labels this as a screening result. It does not determine insurance requirements, establish a property’s actual flood history or resolve the legal effect of a map amendment. Model uncertainty and missing detail do not become certainty merely because a color is displayed on a map.
Verify the site-specific question
For a property decision, locate the official FEMA map products, effective date and any relevant amendments. Check where the structure lies and consult the responsible floodplain authority or qualified professional for the specific determination needed. Local drainage, stormwater records and elevation evidence may answer questions the regional map does not.
Use the town flood directory to discover screened parcels, then open the property record and source methodology. If you share the result, include the screening method and source date and preserve the distinction between a parcel locator and a confirmed affected building.
