What this check answers
A flood layer describes a mapped scenario and date; it is neither a guarantee of safety outside the layer nor an automatic project decision inside it.
What to verify
- Check the exact parcel on the current official flood-hazard and flood-risk maps.
- Record the scenario, source and publication date shown.
- Ask the designer, water authority and insurer or lender about project-specific consequences where relevant.
