Ahead of any purchase around Primrose, look at the Boone County flood zone map: FEMA's zone label affects insurance, building rules and resale. What this Boone County guide covers: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the Boone County gWorks map.
The Boone County flood zone map: start here
For a tract near Closter, the official source is FEMA's Flood Map Service Center: enter the street address, then open the map view for that panel. Vacant ground around Closter can still be found: search the nearest road then click the parcel area.
Where the parcel data lives
Property in and around Loretto appear on the Boone County gWorks map, which opens without registering. Closer to Cedar Rapids, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. For acreage around Primrose, copy the parcel ID before closing the panel; each records desk in the county will want it.
On site with the map
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Loretto, but coverage can be spotty out of town. A screenshot of the parcel near Primrose with its ID is a good backup.
A quick look at the area
Albion is the county seat, which is where the courthouse records live. Other places on the map include St. Edward, Cedar Rapids, Petersburg, and Primrose, where town lots give way to larger tracts. About 5,310 people call Boone County home (Census estimate, 2023) spread over roughly 687 square miles. The county was organized in 1871, and some chains of title near Loretto are long.
Recorded documents worth pulling
Before you sign anything, pull the recorded deed through the Register of Deeds; the parcel line is a drawing of it, which applies near Raeville as much as anywhere. For property near Loretto, bring the document number listed on the parcel record so staff can find the deed fast.
Which office to call
Recorded documents for a parcel near Cedar Rapids come from the Register of Deeds, sometimes only in person. Questions about what you can build around Akron need the planning or permitting office, and the answer depends on jurisdiction.
Low spots and local drainage
Low-lying fields near Raeville may not have detailed mapping, so walk the land after rain. Wet ground around Loretto is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
When a parcel crosses a boundary
The county meets Antelope County, Greeley County, Madison County, Nance County, and Platte County, all with their own assessor records, especially near Loretto. A tract near the line by Cedar Rapids can show up in two county records, so open the adjacent map as well. For property near Primrose, our state page links every bordering county map across Nebraska.
Reading A, AE and X
With a lot near Akron, zones beginning with A or V are Special Flood Hazard Areas, meaning a 1% or greater chance of flooding each year. With a lot near St. Edward, minimal risk is not no risk: FEMA notes that floods happen outside mapped zones too.
What the map can't tell you
Tax maps are drawn for assessment, not surveyed, so the edge of a yard near Loretto can sit a few yards off the line on screen. Owner names and values update on a schedule, so a recent sale near Albion may not show yet.
Lining it up with the parcel map
FEMA's map shows zones but not ownership, so check the Boone County gWorks map too for the outline of the tract near Primrose.
What a flood zone means for a buyer
Closer to St. Edward, an Elevation Certificate from a surveyor helps: it compares the building to the BFE. New construction in a floodplain near St. Edward can trigger elevation rules; ask the local floodplain administrator before you plan.
Questions to ask before you buy
Ask the seller for any Elevation Certificate for the house near St. Edward; getting a quote early avoids surprises.
Reading the legal description
Nebraska uses the Public Land Survey System, so rural legal descriptions near Cedar Rapids cite section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though sections near Akron can be irregular. Write down the legal description for the tract near Petersburg before you request a deed or survey.

Generally, the BFE is printed in AE zones on FEMA's map; surveyors near Raeville use it often.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
