The Latah County flood zone map question tends to arrive at a bad moment: a lender's letter, an insurance quote, or a permit counter in Bovill. For any tract in Latah County, Idaho, the answer affects insurance, permits and resale.
Below are the FEMA links, a plain reading of the zone labels, notes on where water shapes land around Bovill, and short answers to common questions.
Where to see the official Latah County flood zone map
Open the FEMA Flood Map Service Center and type a county street address, say one in Juliaetta. Search returns the effective FIRM panel for the spot in Latah County, plus any pending changes FEMA has posted. If the PDF panel for Latah County is hard to read, try FEMA's National Flood Hazard Layer viewer; zoom to the piece of ground near Kendrick and click. Switch to the Idaho statewide Parcels layer in ArcGIS Map Viewer and find the same piece of ground near Kendrick. If the Latah County viewer has a floodplain layer, treat it as a convenience copy and confirm on FEMA's map.

Recorded documents in Latah County, Idaho

Zone A, AE and X in plain English
For a lot in Juliaetta, the label matters more than the color: A and V zones are Special Flood Hazard Areas, meaning FEMA estimates a 1-percent annual chance of flooding. Zone AE near Kendrick means FEMA published a base flood elevation; plain Zone A means no detailed elevation was studied. Land near Kendrick in shaded X (Zone B on older maps) sits in the moderate band between the 100-year and 500-year floods. Clear, unshaded X near Juliaetta is outside the 500-year floodplain.
Low ground and small streams around Juliaetta
A creek near Kendrick that lists no detailed zone can still flood; FEMA says moderate- and low-risk areas still carry risk.

Town lots cluster around Moscow, the county seat, and Bovill, Deary, Genesee, and Juliaetta. Unincorporated communities in the county, including Princeton, Viola, and Avon, show up as small groups of parcels along the roads.

Insurance, permits and map changes
Lenders watch the zone closely on Latah County properties. Where a building in Juliaetta sits in a Special Flood Hazard Area and carries a federally backed mortgage, the lender must require flood coverage, as long as Latah County or the town participates in the NFIP. Outside the A zones around Kendrick, insurance is a choice, not a mandate; pricing a policy for land near Kendrick is still worth a call. If a building near Kendrick sits above the flood line, the owner can ask FEMA for a Letter of Map Amendment (LOMA); a surveyor near Kendrick can supply the elevation data. Building or filling inside a mapped zone near Juliaetta typically needs a floodplain permit, and the building office serving Kendrick explains the steps.
