A Navajo County flood zone map check belongs in the due diligence for any Navajo County property, from a house lot in Pinetop-Lakeside to farm ground near Kayenta. You can check it yourself for any Pinetop-Lakeside address in a few minutes.
We'll cover finding a Navajo 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 Navajo County flood zone map
The authoritative source for a Navajo County flood zone map is FEMA, so begin at the FEMA Flood Map Service Center. Search returns the effective FIRM panel for the spot in Navajo County, plus any pending changes FEMA has posted. For an interactive view of the county, FEMA's National Flood Hazard Layer viewer draws the zones over aerial imagery and reports the zone wherever you click near Pinetop-Lakeside. Next, the Navajo County parcel viewer confirms which Navajo County parcel you're looking at. Match the Navajo County lines and acreage to the FEMA view, since flood maps don't draw property lines in detail.
Step one: the free Navajo County viewer
The county's own public map is the Navajo County parcel viewer, and it opens without an account for parcels in Snowflake and the rest of the county. Most people locate their Navajo County tract fastest by searching an address in Winslow, then clicking the outline. Bookmark our Navajo County page too; it tracks the official Arizona link if it moves and lists the maps around Snowflake.
Zone A, AE and X in plain English
On the FIRM covering Navajo 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 Navajo County tract lists Zone AE, there's a base flood elevation to compare a building against; in Zone A there is not one. Land near Snowflake 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 Navajo County panel means minimal risk.
Unmapped creeks in Navajo County
A low spot on a Navajo County tract outside any mapped zone, so treat an unmapped channel as a reason to ask questions, not proof the ground stays dry.
Tracts that cross the Navajo County line
Navajo County borders Apache County, Coconino County, Gila County, Graham County, and San Juan County, UT, and each keeps its own parcel map and records. Our Arizona page links each map neighboring Navajo County.
Recorded documents in Navajo County, Arizona
The parcel layer for Navajo County points back to recorded deeds and plats, kept by the county's recording office (its title varies by state). A deed book and page or instrument number on the county record is the quickest route to order the document for a lot in Holbrook.
Getting oriented in Navajo County, AZ
Holbrook is the county seat, and Show Low, Winslow, Kayenta, and Pinetop-Lakeside are among the other towns on the county map. Unincorporated communities in Navajo County, including Chilchinbito, Cibecue, and Clay Springs, display up as small groups of parcels along the roads. Navajo County had an estimated 109,175 people in 2023 (Census Bureau), spread across about 9,949 square miles. Outside Show Low, most of the county map is farm, ranch or timber ground with large, irregular tracts. Landforms such as the Monument Valley and Keams Canyon shape where roads and homesites fall in Navajo County. With a founding date of 1895, Navajo County has long chains of title on some rural tracts.
Insurance, permits and map changes
The zone lists up again when a loan on a house near Snowflake is underwritten. When a county home sits in a Special Flood Hazard Area and carries a federally backed mortgage, the lender must require flood coverage; that applies where the local government around Snowflake is in the National Flood Insurance Program. In Zone X near Pinetop-Lakeside, coverage is optional; pricing a policy for land near Snowflake is still worth a call. When a Navajo County homesite is on a rise inside a mapped zone, FEMA's LOMA process allows a review, most often backed by an elevation certificate from a surveyor who works in Navajo County. Placing fill on low ground near Pinetop-Lakeside often requires a permit and an elevation check, so call the county or the town office in Pinetop-Lakeside before work starts.
Quick answers for Navajo County
What does 100-year flood mean for Navajo County land?
Not at all; a Navajo County tract in that zone carries a 1-in-100 chance in any single year, so floods can come in back-to-back years.
Do I need a permit to build in the floodplain near Show Low?
Building in a Special Flood Hazard Area near Show Low most often needs a floodplain permit and may require elevating the structure, so check with the county floodplain administrator.
Where do I get an elevation certificate in Navajo County?
A licensed land surveyor or engineer prepares it, and the building office serving Show Low may already have one on file for newer construction.
Is flood insurance required for a Zone X lot in Show Low?
For a Zone X house near Kayenta, federal rules don't require flood insurance; buying it is still a choice worth pricing.
My lot in Show Low lists Zone AE. What does that mean?
Zone AE on a lot in Show Low is a mapped 100-year floodplain with a base flood elevation, so mandatory insurance rules apply to federally backed mortgages.
What does BFE mean on the flood map for Show Low?
Near Kayenta, the base flood elevation marks how high the 100-year flood is expected to rise, and a surveyor compares the building near Show Low to it.
