Before an offer near Westphalia, check the Harlan flood zone map: a mapped flood zone changes insurance, permits and resale. In this Harlan guide: finding the address on FEMA's map, reading the zone codes, and confirming the outline on the county map.
Checking the Harlan flood zone map step by step
Start with FEMA's Flood Map Service Center: search an address around Tennant, then open the map view for that panel. A tract near Tennant without an address is still easy to locate: zoom in from the nearest road and click the spot.
Pulling up a parcel
Begin with the Shelby County Beacon site; it covers every assessed parcel in the county, Portsmouth included. If you're looking near Earling, enter a street address, an owner's name or a parcel number, and the matching parcel lights up. On ground around Westphalia, a pop-up or side panel normally shows the owner of record, acreage on the tax roll, a parcel ID and sometimes recent sales.
Where Harlan fits in
Harlan lies within Shelby County, Iowa, so its parcels are on the county's map. As the county seat, Harlan hosts the courthouse, which puts the County Recorder close by. Near Tennant, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Lots just outside the town limits toward Kirkman often answers to county rules, not municipal ones.
Reading the legal description
Iowa follows the Public Land Survey System, which means a tract near Portsmouth is described by section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though real sections near Tennant vary in size. Keep the legal description for land near Panama for any title or survey request.
Decoding the flood zone labels
Zone AE includes a base flood elevation (BFE), while plain Zone A does not; that elevation drives building rules near Tennant. For a tract near Westphalia, shaded Zone X is moderate risk, between the 1% and 0.2% annual chance floods; plain X, or C on older maps, is minimal risk.
Lining it up with the parcel map
FEMA's map shows zones but not ownership, so pair it with the Shelby County Beacon site to confirm you have the right parcel near Portsmouth.
Beyond the mapped zones
Low-lying fields near Westphalia may not have detailed mapping, so walk the land after rain. Marshy spots near Westphalia can limit building too; check the National Wetlands Inventory mapper for a first look.
Getting your bearings
Harlan serves as the county seat, which is where the courthouse records live. You'll also find Westphalia, Kirkman, Tennant, and Panama, each with its own cluster of lots. Roughly 11,806 people call Shelby County home (Census Bureau estimate, 2023) across roughly 591 square miles. Shelby County was organized in 1851, which matters when you trace an old farm's title.
What a flood zone means for a buyer
For a tract near Panama, an Elevation Certificate from a surveyor helps: it compares the building to the BFE. New construction in a floodplain near Kirkman usually means extra permit review; check with the county or town building office before you plan.
Backing up the map with records
The map is an index, not the title: recorded deeds, subdivision plats and easements covering ground around Tennant sit with the County Recorder. Long-held tracts around Westphalia can sit on a long string of deeds, so a title company can sort it out if money is changing hands.
What the map can't tell you
Parcel lines are drawn for taxes, not surveyed, so a fence near Tennant can sit a few yards off the line on screen. With a lot near Kirkman, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Who handles what
Questions about value or the owner field for land near Westphalia belong with the County Assessor, since that office keeps the assessment data. Questions about what you can build around Kirkman are for the local planning and health departments, depending on whether the land is inside town limits.
Questions to ask before you buy
Ask the seller about past flood claims on the property near Tennant; an insurance quote early avoids surprises.
