Look up the Henry County flood zone map step by step
Start at the FEMA Flood Map Service Center and enter the property address in Rome or anywhere else in the county. The site returns the effective Flood Insurance Rate Map (FIRM) panel covering that Rome location, which you can view or download. For an interactive view of the county, try FEMA's National Flood Hazard Layer viewer; zoom to the tract close to Coppock and click. Switch to the Henry County Beacon site and locate the same tract close to Coppock. The Henry County record gives the parcel identifier and legal description that an insurer or lender near Rome may ask for.
Step one: the free Henry County viewer
Henry County publishes its parcels on the Henry County Beacon site, which runs on Schneider Geospatial's Beacon platform, free to use for a lot in New London or a tract close to Hillsboro. Search a Hillsboro address on the county search page, read the report, then jump to the map to see that parcel's outline. Our Henry County, IA page keeps the official link and the maps next door to Hillsboro in one place.
Recorded documents in Henry County, Iowa
The parcel layer for Henry County points back to recorded deeds and plats, kept by the county's recording office (its title varies by state). Easements and access rights near Salem live in recorded documents, so read the deed, not just the county map.
High, moderate and minimal risk in Henry County
On the FIRM covering Henry County, zones that start with A or V are Special Flood Hazard Areas, defined by a 1-percent annual chance of being flooded. A surveyor working near Rome uses the base flood elevation printed for AE zones; unnumbered A zones don't have one. If a Henry County parcel shows shaded Zone X, it is moderate risk, between the 1-percent and 0.2-percent annual chance lines. Unshaded Zone X near Coppock is minimal risk.

When the map affects a deal
Lenders watch the zone closely on Henry County properties. If a house near Coppock falls inside an A or V zone and is financed by a regulated or federally insured lender, flood insurance is mandatory, provided the community near Rome takes part in the National Flood Insurance Program. In Zone X near Rome, coverage is optional, although a lender in Iowa can still ask for it. When a Henry County homesite is on a rise inside a mapped zone, the owner can ask FEMA for a Letter of Map Amendment (LOMA), generally backed by an elevation certificate from a surveyor who works in Henry County. Building or filling inside a mapped zone near Rome often requires a permit and an elevation check, and the building office serving Coppock explains the steps.
Henry County flood zones questions
What does 100-year flood mean for Henry County land?
Not at all; a county tract in that zone carries a 1-in-100 chance in any single year, and two floods in one decade near Salem are possible.
What if FEMA's map is wrong about my house near Olds?
FEMA reviews requests such as a LOMA for Henry County properties; start with an elevation certificate.
My lot in Salem shows Zone AE. What does that mean?
For a Henry County parcel, Zone AE means a Special Flood Hazard Area with a 1-percent annual chance of flooding and a published base flood elevation.
What is a base flood elevation for a Henry County property?
For a county property in Zone AE, the BFE is the height floodwater is expected to reach in the 1-percent-annual-chance flood, and a surveyor compares the building near Salem to it.
Who prepares an elevation certificate for a house in Salem?
Hire a professional surveyor or engineer who works in Henry County; ask the local floodplain office first in case one exists.
How can I check a Henry County, IA flood zone?
Look it up at FEMA's Flood Map Service Center, then match the parcel lines in the Henry County Beacon site; for land near Olds, a zone starting with A or V is high risk.
