Weighing a property around Tiffin? A quick look at the Iowa City flood zone map shows whether it sits in a FEMA flood zone, and it costs nothing to check. This Iowa City guide covers: locating a parcel on FEMA's map, decoding A, AE and X, and pairing it with the Johnson County Beacon site.
Getting started with the Iowa City flood zone map
Flood zones come from FEMA's Flood Map Service Center: search an address around Lone Tree, then open the map view for that panel. Vacant ground around Solon is still easy to locate: pan from the closest town and click the spot.
The free map to start with
Your first stop is the Johnson County Beacon site; it maps each assessed parcel in the county, Hills included. Around Coralville, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. If you're looking near Hills, a pop-up or side panel usually lists the owner of record, assessed acreage, a parcel ID and sometimes recent sales.
What to request from a seller
Request for any Elevation Certificate for the house near Coralville; getting a quote early keeps the budget honest.
Which office to call
Questions about value or the owner field for land near Solon are handled by the County Assessor, the office behind the parcel record. Questions about what you can build around Hills go to planning, building or health offices, and the answer depends on jurisdiction.
What the map can't tell you
Tax maps are drawn for assessment, not measured on the ground, so a tree line near Solon often sits some distance off the line on screen. Closer to Lone Tree, records update in batches, so a deed recorded last month might lag behind.
City limits and county records
Iowa City sits in Johnson County, Iowa, and the county assessor maps its lots. As the county seat, Iowa City hosts the courthouse, which puts the County Recorder close by. For a home near Tiffin, City or town hall handles matters such as zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Acreage past the city limits toward Solon often answers to county rules, not municipal ones.
Reading A, AE and X
An AE label carries a published BFE, which plain A zones lack; surveyors near North Liberty use that number. Out toward Coralville, a shaded X area marks moderate flood hazard, roughly the 100- to 500-year range; plain X, or C on older maps, is minimal risk.
Low spots and local drainage
Creeks and ditches near Solon aren't always studied in detail, so walk the land after rain. Marshy spots near Coralville can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
Parcel lines plus flood zones
FEMA's map shows zones but not ownership, so check the Johnson County Beacon site too for the outline of the tract near Hills.
Legal descriptions in Iowa
Iowa is laid out under the Public Land Survey System, so rural legal descriptions near Solon cite section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though corrections make some sections near North Liberty odd-sized. Keep the legal description for land near Hills for any title or survey request.
Recorded documents worth pulling
When the details count, request the recorded deed from the County Recorder; the parcel map near Coralville only summarizes it. Older tracts around Tiffin may go back through several deeds, and a title company is worth hiring on a real sale.
Money questions tied to the zone
In and around Solon, get the Elevation Certificate if one exists: it compares the building to the BFE. New construction in a floodplain near Coralville can trigger elevation rules; call the permitting office early.
On site with the map
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Lone Tree, though signal can drop in rural spots. A printout of the tract near Solon helps when you meet an owner or agent.
Johnson County in a few facts
Iowa City is the county seat, where most land records are kept. Other places on the map include Coralville, Hills, Tiffin, and North Liberty, each with its own cluster of lots. About 157,528 people call Johnson County home (Census estimate, 2023) on about 613 square miles. Johnson County was formed in 1837, and some chains of title near Lone Tree are long.
Iowa City: common questions
Where can I see the Iowa City flood zone map for free?
For most people, FEMA's free map shows the zone for any spot near Solon, and the zone code appears on the map.
Does the county parcel map show flood zones around Solon?
For most people, a flood layer may appear in the Johnson County Beacon site layer list; confirm a lot near Hills on FEMA's map either way.
Do I need to worry about flooding in Zone X in Iowa City?

When is flood insurance required near Hills?
