Before an offer near Superior, check the Mineral County flood zone map: FEMA's zone label affects insurance, permits and resale. What this Mineral County guide covers: finding the address on FEMA's map, reading the zone codes, and pairing it with the Mineral County ArcGIS parcel map.
The Mineral County flood zone map: start here
With a lot near Haugan, start with FEMA's Flood Map Service Center: enter the street address, and choose the dynamic map. Vacant ground around Riverbend can still be found: zoom in from US Route 10 and click the spot.
Pulling up a parcel
Your first stop is the Mineral County ArcGIS parcel map; it covers every tax parcel in the county, Riverbend included. If you only know roughly where the land is, pan along US Route 10 until the lines appear, then click inside the one you want, which applies near Riverbend as much as anywhere. For a tract near De Borgia, the parcel card normally shows the owner of record, assessed acreage, a parcel ID and often a sale date.
When a parcel crosses a boundary
Mineral County meets Clearwater County, ID, Shoshone County, ID, Missoula County, and Sanders County, all with their own assessor records. Ground near Saltese that runs to the line may show up in two county records, so look at the neighboring map as well. In and around Alberton, the Platbookmapper state page lists every neighboring county map across Montana.
Low spots and local drainage
Low-lying fields near Riverbend aren't always studied in detail, so walk the land after rain. Wetlands near Saltese can limit building even outside a flood zone; check the National Wetlands Inventory mapper for a first look.
What the zone letters mean
Zone AE comes with a base flood elevation, which plain A zones lack; surveyors near Cyr use that number. Out toward Cyr, shaded Zone X marks moderate flood hazard, roughly the 100- to 500-year range; unshaded X is minimal risk.
Parcel lines plus flood zones
FEMA doesn't draw property lines, so check the Mineral County ArcGIS parcel map too to confirm you have the right parcel near Cyr.
On site with the map
Most viewers work in a phone browser, useful out on a road near Saltese, so load it before you lose signal. A saved image of the lot near De Borgia and its lines helps when you meet an owner or agent.
Legal descriptions in Montana
Montana is laid out under the Public Land Survey System, which means a tract near De Borgia is described by section, township and range. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though sections near Lolo National Forest can be irregular. Keep the legal description for land near Riverbend before you request a deed or survey.
What to request from a seller
With a lot near De Borgia, ask the seller whether the home has flooded before closing; an insurance quote early keeps the budget honest.
Which office to call
Questions about value or the owner field for land near Saltese are handled by the Montana Department of Revenue, which maintains the tax roll. Questions about what you can build around Alberton are for the local planning and health departments, and the answer depends on jurisdiction.
Recorded documents worth pulling
Before you sign anything, request the recorded deed through the County Clerk and Recorder; the parcel line is a drawing of it, for land near Cyr included. Older tracts near Riverbend can trace back through many deeds, and a title company is worth hiring on a real sale.
Money questions tied to the zone
For property near Haugan, get the Elevation Certificate if one exists: it can change the insurance price a lot. New construction in a floodplain near Haugan usually means extra permit review; check with the county or town building office early.
A quick look at the area
Superior is the county seat, where most land records are kept. Smaller places on the map include Alberton, Cyr, De Borgia, and Haugan, where town lots give way to larger tracts. Around 5,090 people call Mineral County home (Census Bureau estimate, 2023) across roughly 1,220 square miles. The county was formed in 1914, and some chains of title near Alberton are long. Features like Lolo National Forest make handy reference points on the map.

Is AE a high-risk flood zone near Lolo National Forest?
Near De Borgia, AE is a Special Flood Hazard Area with a published base flood elevation; unnumbered A zones don't list one.
How do I check the flood zone for an address near Lolo National Forest?
Generally, look up the spot near De Borgia in FEMA's National Flood Hazard Layer viewer, which takes a couple of minutes.
What is a base flood elevation near Superior?
For a tract near Alberton, the BFE is printed in AE zones on FEMA's map, and an Elevation Certificate compares the building to it.
Can a flood zone near Alberton change?
Near Haugan, FEMA revises flood maps panel by panel as new studies finish, so look at the panel date.
Where is the legal description for land near De Borgia?
Closer to Alberton, it's the formal description of the land in the deed, and the parcel record often summarizes it.
