How to use the Aroostook County flood zone map
Start at the FEMA Flood Map Service Center and enter the property address in Ashland or anywhere else in the county. Download the FIRM panel FEMA lists as effective for that part of Aroostook County. On acreage outside Ashland, FEMA's National Flood Hazard Layer viewer draws the zones over aerial imagery; zoom to the tract near Caribou and click. Then open the Maine GeoLibrary Parcel Viewer for Aroostook County to confirm the parcel near Ashland. Match the Aroostook County lines and acreage to the FEMA view, since flood maps do not draw property lines in detail.
Search Aroostook County parcels by owner, address or ID
For Aroostook County, the free public parcel layer is state-run: open the Maine GeoLibrary Parcel Viewer and pan to Blaine. Use the search box for an address in Amity or a parcel number, or simply zoom in and click a tract near Blaine.

High, moderate and minimal risk in Aroostook County
For a lot in Ashland, the label matters more than the color: A and V zones are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any given year (the base or 100-year flood). A surveyor working near Ashland uses the base flood elevation printed for AE zones; unnumbered A zones do not have one. Shaded Zone X around Ashland falls between the base flood and the 500-year flood. Unshaded Zone X near Caribou is minimal risk.
Unmapped creeks in Aroostook County
Small streams and ditches near Ashland may not be studied in detail can still flood; FEMA says moderate- and low-risk areas still carry risk.
Where Aroostook County land records are kept
Deeds and plats behind the Aroostook County map are kept by the county's recording office; the official Aroostook County website names which office that is. Copy the parcel ID and legal description from the county record well before you request a deed for land near Allagash.
From Houlton to the back roads
From Houlton, the seat of the county, the map spreads out to Caribou, Presque Isle, Allagash, and Amity. Smaller places such as Cyr Plantation, Garfield Plantation, and Glenwood Plantation appear on the county map as little clusters of lots. Aroostook County had an estimated 67,351 people in 2023 (Census Bureau), spread across about 6,671 square miles. Beyond the town lots in Presque Isle, expect big rural parcels across the county. Aroostook County was organized in 1839, so deeds for older farms near Amity can run back a long way.
When the map affects a deal
The zone displays up again when a loan on a house near Caribou is underwritten. If a barn or house outside Ashland falls inside an A or V zone and is financed by a regulated or federally insured lender, federal rules call for flood insurance, provided the community near Ashland takes part in the National Flood Insurance Program. Outside the A zones around Caribou, coverage is optional, although some lenders require it anyway. When an Aroostook County homesite is on a rise inside a mapped zone, FEMA's LOMA process allows a review, supported by elevation data from a professional surveyor. New construction in an Aroostook County Special Flood Hazard Area has to meet local floodplain rules; the Aroostook County floodplain administrator can say what applies.

Is flood insurance required for a Zone X lot in Presque Isle?
FEMA does not require it for a Zone X lot in Presque Isle, but coverage is available and some lenders ask for it.

FEMA reviews requests such as a LOMA for Aroostook County properties; start with an elevation certificate.
