Decoding the flood zone labels
Zone AE comes with a base flood elevation, which plain A zones lack; surveyors near Craters of the Moon National Monument and Preserve use that number. If the land is near Craters of the Moon National Monument and Preserve, shaded Zone X is moderate risk, between the 1% and 0.2% annual chance floods; plain X, or C on older maps, is minimal risk.
Taking the map into the field
Most viewers work in a phone browser, which helps when you're standing on land near Heyburn, so load it before you lose signal. A printout of the tract near Kimama keeps working without signal.
Where the recorded documents are
The map is an index, not the title: deeds, plats and easements covering ground around Craters of the Moon National Monument and Preserve are filed with the County Recorder (the county clerk serves as recorder). Long-held tracts around Kimama can trace back through many deeds, so a title company can sort it out on a real sale.
Lining it up with the parcel map
FEMA doesn't draw property lines, so check the Minidoka County ArcGIS parcel map too to see exactly which lot near Paul you're looking at.
Water near Burley
Creeks and ditches near Craters of the Moon National Monument and Preserve may not have detailed mapping, so ask neighbors about past flooding. Wetlands near Snake River Plain can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
Money questions tied to the zone
For land near Craters of the Moon National Monument and Preserve, get the Elevation Certificate if one exists: it compares the building to the BFE. New construction in a floodplain near Paul can trigger elevation rules; ask the local floodplain administrator before you plan.
