The Marion flood zone map: start here
The official source is FEMA's Flood Map Service Center: search an address around Cedar Rapids, then open the map view for that panel. Rural land near Robins with no street number is still easy to locate: search the nearest road and click inside the land.
The viewer Linn County publishes
The official parcel map for this area is the Linn County parcel viewer, and it opens in a browser with no account. For a parcel near Bertram, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. If you're looking near Robins, write down the parcel ID before closing the panel; every office in the county will want it.
Which office to call
Anything recorded against property around Hiawatha are with the County Recorder, sometimes only in person. Zoning, permits and septic questions near Springville go to planning, building or health offices, depending on whether the land is inside town limits.
Marion, IA: the basics
Marion sits in Linn County, Iowa, which means parcel data comes from the county. For a parcel near Hiawatha, city or town hall handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Acreage past the town limits out by Robins usually falls under county rules rather than the town's.
Reading A, AE and X
An AE label comes with a base flood elevation, and an unnumbered A zone has none; that elevation drives building rules near Cedar Rapids. Around Robins, 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.
Land on the county line
Linn County meets Benton County, Buchanan County, Cedar County, Delaware County, and Iowa County, and each of those keeps its own parcel map. Ground near Cedar Rapids that runs to the line may be split in two county records, so look at the adjacent map before you assume the acreage. For a parcel near Hiawatha, our state page links each bordering county map for Iowa.
A short flood checklist
Ask the seller for any Elevation Certificate on the property near Cedar Rapids; getting a quote early avoids surprises.
Water near Bertram
Small streams around Alburnett may not have detailed mapping, so look for water marks and debris lines. Wet ground around Cedar Rapids is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
Linn County in a few facts
Cedar Rapids holds the county offices, where most land records are kept. Other places on the map include Robins, Hiawatha, Springville, and Bertram. About 228,972 people live in the county (Census estimate, 2023) on about 717 square miles around Bertram. Linn County was formed in 1837, so old deeds can run back a long way.
Matching the zone to the lot lines
FEMA doesn't draw property lines, so open the Linn County parcel viewer next to confirm you have the right parcel near Bertram.
What a flood zone means for a buyer
For a parcel near Springville, get the Elevation Certificate if one exists: it records the building's elevation against the base flood. New construction in a floodplain near Bertram can trigger elevation rules; check with the county or town building office before you plan.
What the map can't tell you
Listed acreage is a tax-roll number; only a licensed surveyor can set the real corners for a parcel near Cedar Rapids. For land near Springville, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Recorded documents worth pulling
The map is an index, not the title: recorded deeds, plats and easements covering ground around Hiawatha sit with the County Recorder. For acreage around Hiawatha, have ready the document number listed on the parcel record and the lookup takes minutes.
Marion: common questions
How often are flood maps updated for land near Hiawatha?
It depends, but zones near Hiawatha can shift when FEMA updates a panel; check the effective date on the panel.
What is a base flood elevation in Marion?
It depends, but a BFE near Hiawatha tells builders how high the lowest floor should be, and an Elevation Certificate compares the building to it.
What if the flood map is wrong for my lot near Robins?
Good question; you can ask FEMA for a LOMA if surveyed elevations show the building near Springville is above the BFE; a surveyor's elevation data supports it.
Can I see flood zones on the Linn County parcel viewer?
It depends, but a flood layer may appear in the county parcel viewer layer list, but FEMA's own map is the official source around Alburnett.
How do I save a parcel from the viewer in Marion?
Some viewers offer PDF export, and it's worth keeping the parcel ID visible for land near Cedar Rapids.
