Is that lot in Dunedin in a flood zone? The Pinellas County flood zone map answer comes from FEMA, and it is free to look up. FEMA's free Flood Map Service Center and the Pinellas County parcel viewer answer it together.
Below are the FEMA links, a plain reading of the zone labels, notes on where water shapes land around Dunedin, and short answers to common questions.
How to use the Pinellas County flood zone map
Start at the FEMA Flood Map Service Center and enter the property address in Largo or anywhere else in the county. If a parcel near Clearwater has no street number yet, search the nearest road and pan to it. If the PDF panel for Pinellas County is hard to read, FEMA's National Flood Hazard Layer viewer draws the zones over aerial imagery, which shows how much of a Pinellas County parcel sits inside the zone. Switch to the Pinellas County parcel viewer and track down the same parcel near Clearwater. Match the Pinellas County lines and acreage to the FEMA view, since flood maps don't draw property lines in detail.
Step one: the free Pinellas County viewer
For land around Belleair Beach, open the Pinellas County parcel viewer; it is the map Pinellas County itself publishes. Most people track down their Pinellas County tract fastest by searching an address in Belleair Beach, then clicking the outline. For a backup route to the map covering Belleair Beach, our Pinellas County directory entry keeps the link current.

Near the edge of the county, check the next map over: Hillsborough County and Pasco County all border it. Our Florida page links each map neighboring Pinellas County.
Zone A, AE and X in plain English
For a lot in Largo, 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. A surveyor working near Largo uses the base flood elevation printed for AE zones; unnumbered A zones don't have one. If a Pinellas County parcel shows shaded Zone X, it is moderate risk, between the 1-percent and 0.2-percent annual chance lines. Clear, unshaded X near Largo is outside the 500-year floodplain.
Waterfront parcels near Clearwater
In Pinellas County, look closest at tracts along Tampa Bay. Waterfront and bottomland parcels near Largo frequently carry a zone along one edge, so check where the buildable part sits. A creek near Clearwater that shows no detailed zone, which is why it is worth walking the ground after a heavy rain.
Towns and land across Pinellas County
Town lots cluster around Clearwater, the county seat, and Belleair Beach, Belleair Bluffs, Dunedin, and Gulfport. Unincorporated communities in the county, including Bardmoor, Bay Pines, and Bear Creek, display up as small groups of parcels along the roads. Roughly 274 square miles of land and about 961,596 residents (2023 estimate) make up Pinellas County. Much of Pinellas County is built out, so most clicks near Dunedin land on platted lots.
Where Pinellas County land records are kept
Deeds and recorded plats for Pinellas County are filed with the clerk of the circuit court (official records), while parcel values come from the county property appraiser. Florida splits the job, and Pinellas County is no exception: the property appraiser values parcels and keeps the assessment maps, while the clerk of court records deeds, mortgages and plats. Easements and access rights near Indian Rocks Beach live in recorded documents, so read the deed, not just the county map.
When the map affects a deal
Insurance is the practical stake for a Pinellas County buyer. If a house near Clearwater falls inside an A or V zone and secures a loan from a federally regulated or insured lender, federal rules call for flood insurance; that applies where the local government around Clearwater is in the National Flood Insurance Program. Outside the A zones around Clearwater, insurance is a choice, not a mandate, although some lenders require it anyway. When a county homesite is on a rise inside a mapped zone, the landowner can ask FEMA for a Letter of Map Amendment (LOMA); a surveyor near Clearwater can supply the elevation data. Adding on to a house near Clearwater inside the zone typically needs a floodplain permit, so call the county or the town office in Largo before work starts.
Pinellas County flood zones questions

Can I build in a flood zone in Pinellas County?
Building in a Special Flood Hazard Area near Dunedin typically needs a floodplain permit and may require elevating the structure, so check with the county floodplain administrator.
Does a 100-year floodplain near Largo flood only once a century?
No, ground around Dunedin mapped that way has a 1-percent chance of flooding every year, so floods can come in back-to-back years.
What does BFE mean on the flood map for Dunedin?
For a Pinellas County property in Zone AE, the BFE is the height floodwater is expected to reach in the 1-percent-annual-chance flood; elevation certificates in Pinellas County are measured against it.
