Frequently asked questions
- How much of Madison County, Kentucky is in a FEMA flood zone?
- Land Owl maps 16,001 acres of Madison County, Kentucky inside a Special Flood Hazard Area, which is 5.6% of the land FEMA has flood-mapped in the county. That is a regulatory designation used for floodplain management and federal flood-insurance requirements — it is not a prediction that the land will flood.
- Is this flood zone map free to use?
- Yes. This map is free to view. A free Land Owl account unlocks the other data layers, parcel boundaries and ownership records.
- Where does this data come from?
- Land Owl maps flood zones from FEMA's National Flood Hazard Layer (NFHL), the digital record of the effective Flood Insurance Rate Maps. It is a screening view, not a flood determination: FEMA revises maps, 495 US counties have never had a digital FIRM published at all, and a lender or insurer will ask for the official record. Check the FEMA Map Service Center, or ask your local floodplain administrator, before you rely on a zone.
- Is land outside the flood zone safe from flooding?
- No. A Special Flood Hazard Area marks where FEMA has studied and mapped a 1% annual chance of flooding; ground outside one has a lower mapped risk, not no risk, and some of it has never been studied at all. Roughly a quarter of US flood-insurance claims come from outside high-risk zones.
- What is the difference between a 100-year and a 500-year flood zone?
- They are shorthand for annual probability, not for how often a flood happens. A 100-year flood zone has a 1% chance of flooding in any given year; a 500-year zone has a 0.2% chance. Either can flood twice in a decade — the odds reset every year.
