Land along Lake Byllesby and the flats outside Empire are where a Dakota County flood zone map lookup matters most. You can check it yourself for any Empire address in a few minutes.
We'll cover finding a Dakota County address on FEMA's map, what Zone A, AE and X mean, how the county viewer fits in, and what to do if the map looks wrong.
How to check the Dakota County flood zone map
The authoritative source for a Dakota County flood zone map is FEMA, so begin at the FEMA Flood Map Service Center. The site returns the effective Flood Insurance Rate Map (FIRM) panel covering that Empire location, which you can view or download. On acreage outside Empire, FEMA's National Flood Hazard Layer viewer draws the zones over aerial imagery and reports the zone wherever you click near Empire. Then open the Dakota County parcel viewer for Dakota County to confirm the parcel near Empire. Laying the county parcel outline beside the FEMA shading shows if a homesite near Apple Valley sits above or inside the zone.
Step one: the free Dakota County viewer
Dakota County publishes its parcels on the Dakota County parcel viewer, free to use for a lot in Coates or a tract near Farmington. Most people track down their Dakota County tract fastest by searching an address in Farmington, then clicking the outline. Our Dakota County, MN page keeps the official link and the maps next door to Farmington in one place.
Zone A, AE and X in plain English
Any Dakota County parcel shaded as Zone A, AE, AH or AO sits in what FEMA calls a Special Flood Hazard Area, land with a 1-percent chance of flooding in any given year (the base or 100-year flood). Zone AE near Apple Valley means FEMA published a base flood elevation; plain Zone A means no detailed elevation was studied. If a Dakota County parcel shows shaded Zone X, it sits in the moderate band between the 100-year and 500-year floods. Unshaded X (or C) on the Dakota County panel means minimal risk.
Creeks, rivers and low ground in Dakota County
In Dakota County, look closest at tracts along Lake Byllesby. Don't assume a tract near Apple Valley is clear because its road frontage sits high. A creek near Apple Valley that shows no detailed zone, which is why it is worth walking the ground after a heavy rain.
Deeds and plats behind the Dakota County map
Deeds and plats behind the Dakota County map are kept by the county's recording office; the official Dakota County website names which office that is. Easements and access rights near Hastings live in recorded documents, so read the deed, not just the county map.
Questions to ask before buying in Dakota County
Request any past flood claims history for a Dakota County property before closing; it tells you more than the map alone. Then call an insurance agent who writes policies around Eagan and get a quote using the zone and the county parcel address.
What a flood zone means for a Dakota County buyer
Lenders watch the zone closely on Dakota County properties. If a barn or house outside Empire is mapped in a high-risk zone and is financed by a regulated or federally insured lender, the lender must require flood coverage; that applies where the local government around Apple Valley is in the National Flood Insurance Program. Outside the A zones around Apple Valley, coverage is optional, although some lenders require it anyway. Where a structure near Empire looks higher than the shading suggests, the owner can ask FEMA for a Letter of Map Amendment (LOMA), supported by elevation data from a licensed land surveyor. Building or filling inside a mapped zone near Empire commonly requires a permit and an elevation check, and the building office serving Apple Valley explains the steps.
Dakota County, MN: common questions
What does 100-year flood mean for Dakota County land?
No; land near Coates in the 100-year floodplain faces a 1-percent annual chance, not a once-a-century schedule.
What does BFE mean on the flood map for Eagan?
On the map covering Eagan, the base flood elevation marks how high the 100-year flood is expected to rise, and it is printed in AE zones.
Can a flood zone in Dakota County be changed?
FEMA reviews requests such as a LOMA for Dakota County properties; start with an elevation certificate.
Is there a floodplain layer in the Dakota County parcel viewer?
Check the layer list in the Dakota County parcel viewer; if Dakota County includes a floodplain layer, confirm the zone on FEMA's map anyway.
Do I need flood insurance in Zone X in Dakota County?
Not under federal rules; Zone X in Dakota County is outside the Special Flood Hazard Area, although a lender can still require coverage.
