Looking at a lot near Vonore? A quick look at the Alcoa flood zone map shows whether FEMA puts it in a high-risk zone, and the lookup is free. What this Alcoa guide covers: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the Tennessee Property Viewer.
Where the Alcoa flood zone map lives
Start with FEMA's Flood Map Service Center: type an address near Maryville, and choose the dynamic map. Rural land near Vonore with no street number can still be found: zoom in from the nearest road and click inside the land.
The viewer Blount County publishes
Begin with the Tennessee Property Viewer; it includes each assessed parcel from Friendsville to Louisville. Closer to Maryville, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. On ground around Maryville, the record panel normally shows the owner of record, acreage on the tax roll, a parcel ID and sometimes recent sales.
Places you'll see on the map
Maryville is the county seat, which is where the courthouse records live. You'll also find Rockford, Louisville, and Friendsville. Roughly 141,456 people live in Blount County (Census estimate, 2023) spread over about 559 square miles. Blount County dates to 1795, and some chains of title near Friendsville are long. Landmarks such as Fort Loudoun Lake make handy reference points on the map near Friendsville.
Alcoa and the county around it
Alcoa is part of Blount County, Tennessee, so its parcels are on the county's map. Near Rockford, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, but the county runs assessment and recording. Acreage past the city limits out by Vonore often falls under county rules rather than the town's.
Neighboring parcel maps
Blount County borders Graham County, NC, Swain County, NC, Knox County, Loudon County, and Monroe County; every one of them runs a separate parcel map. A tract near the line by Maryville can be split in two county records, so look at the adjacent map before you assume the acreage. With a lot near Townsend, our state page lists every neighboring county map for Tennessee.
What the zone letters mean
On ground around Rockford, any A or V zone are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any year. For a home near Rockford, shaded Zone X marks moderate flood hazard, between the 1% and 0.2% annual chance floods; unshaded X is minimal risk.
Field tips
Most viewers work in a phone browser, which helps when you're standing on land near Friendsville, though signal can drop in rural spots. A saved image of the lot near Townsend and its lines helps when you meet an owner or agent.
How land is described here
Rural deeds near Rockford commonly use metes-and-bounds descriptions, which trace the boundary call by call. Subdivision lots in Vonore refer to a recorded plat, making them easier to find. Copy the legal description from the record for the parcel near Vonore for any title or survey request.
Questions to ask before you buy
Request about past flood claims for the house near Townsend; an insurance quote early keeps the budget honest.
Lining it up with the parcel map
FEMA's map shows zones but not ownership, so check the Tennessee Property Viewer too to confirm you have the right parcel near Friendsville.
Lenders and permits
Closer to Vonore, an Elevation Certificate from a surveyor helps: it can change the insurance price a lot. New construction in a floodplain near Friendsville often needs a floodplain permit; call the permitting office before you plan.
What the map can't tell you
The acreage figure is an assessed number; only a licensed surveyor sets the real boundary on land around Vonore. For a home near Townsend, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Backing up the map with records
The map is an index, not the title: recorded deeds, plats and easements for land near Friendsville are filed with the Register of Deeds. Older tracts around Maryville may trace back through several deeds, and a title company can sort it out on a real sale.
Water near Maryville
Low-lying fields near Vonore aren't always studied in detail, so walk the land after rain. Wet ground around Townsend is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
