Is that lot in Hingham in a flood zone? The Hill County flood zone map answer comes from FEMA, and it's free to look up. For any tract in Hill County, Montana, the answer affects insurance, permits and resale.
The sections below go from the FEMA search to the Hill County parcel record, then cover insurance, permits and map changes near Azure.
How to check the Hill County flood zone map
Start at the FEMA Flood Map Service Center and enter the property address in Azure or anywhere else in the county. Download the FIRM panel FEMA lists as effective for that part of Hill County. For an interactive view of Hill County, FEMA's National Flood Hazard Layer viewer draws the zones over aerial imagery, which displays how much of a Hill County parcel sits inside the zone. Next, the Montana Cadastral confirms which Hill County parcel you're looking at. If the Hill County viewer has a floodplain layer, treat it as a convenience copy and confirm on FEMA's map.
Search Hill County parcels by owner, address or ID
For Hill County, the free public parcel layer is state-run: open the Montana Cadastral and pan to Havre. Search Hill County land by owner or geocode, or pan to Havre and click. For a backup route to the map covering Havre, our Hill County directory entry keeps the link current.
High, moderate and minimal risk in Hill County
On the FIRM covering Hill County, zones that start with A or V are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any given year (the base or 100-year flood). Where a Hill County tract displays Zone AE, there's a base flood elevation to compare a building against; in Zone A there isn't one. Land near Hingham in shaded X (Zone B on older maps) sits in the moderate band between the 100-year and 500-year floods. Unshaded X (or C) on the Hill County panel means minimal risk.
Low ground and small streams around Azure
A creek near Hingham that displays no detailed zone can still flood; FEMA says moderate- and low-risk areas still carry risk.
Seller questions about flood history
Buying near Azure? Ask the seller whether the house has flood insurance now and whether it has ever had a claim; an agent in Montana can also pull the flood disclosure if the state requires one. An agent working in Hill County can quote flood coverage once you know the zone for the lot near Hingham.
Floodways and restudies near Azure
Look at the effective date printed on the county panel, since a new study can redraw zones around Havre. Floodways, shown as hatched areas on some panels, are the channel and nearby land that must stay open, and building there near Havre faces the strictest rules.
What drives land use around Havre
Hill County's 2022 business count was 497 establishments, with construction, retail trade, and health care and social assistance the largest groups. Compared with national shares, Hill County leans toward agriculture and forestry support services and utilities, which shapes demand for land near Azure.
Flood insurance and building rules in Hill County
The zone displays up again when a loan on a house near Hingham is underwritten. When a structure near Hingham sits in a Special Flood Hazard Area and carries a federally backed mortgage, flood insurance is mandatory under the Flood Disaster Protection Act, wherever the community joins the NFIP. In Zone X near Azure, insurance is a choice, not a mandate, although a lender in Montana can still ask for it. When a county homesite is on a rise inside a mapped zone, FEMA's LOMA process allows a review; a surveyor near Hingham can supply the elevation data. New construction in a Hill County Special Flood Hazard Area often requires a permit and an elevation check; the Hill County floodplain administrator can say what applies.
