Ahead of any purchase around Danville, pull up the Caledonia County flood zone map: FEMA's zone label affects insurance, building rules and resale. Covered here for Caledonia County: finding the address on FEMA's map, reading the zone codes, and pairing it with the Vermont Parcel Viewer.
Getting started with the Caledonia County flood zone map
If the land is near Groton, the official source is FEMA's Flood Map Service Center: enter the street address, and pick the FIRMette or map view. Rural land near Sheffield with no street number can still be found: zoom in from US Route 2 and click inside the land.
Pulling up a parcel
For property near St. Johnsbury, the no-cost parcel map for this area is the Vermont Parcel Viewer, and anyone can open it without signing up. When a rural tract has no street number, pan along US Route 2 until the lines appear, then click inside the one you want, and that holds around St. Johnsbury too. With a lot near Burke, a pop-up or side panel normally shows the owner of record, assessed acreage, the parcel number and sometimes recent sales.
Limits of the parcel data
For land near Danville, the acreage figure is an assessed number; just a licensed surveyor establishes the real lines on the ground. Closer to Burke, records update in batches, so a deed recorded last month might lag behind.
Caledonia County in a few facts
St. Johnsbury is the county seat, where most land records are kept. You'll also find Barnet, Burke, Danville, and Groton, each with its own cluster of lots. Around 30,610 people call Caledonia County home (Census Bureau estimate, 2023) on about 649 square miles. The county was organized in 1796, which matters when you trace an old farm's title, at least around Sheffield. Places such as Connecticut River and Winooski River help you orient on the aerial around St. Johnsbury.
A short flood checklist
For a parcel near Barnet, ask the listing agent for any Elevation Certificate before closing; an insurance quote early keeps the budget honest.
Deeds, plats and who keeps them
The map is an index, not the title: deeds, plats and easements covering ground around Lyndon Center are filed with the town clerk. On ground around East Burke, bring the instrument number from the tax record so staff can find the deed fast.
Low spots and local drainage
Small streams around Barnet may not have detailed mapping, so walk the land after rain. Wet ground around East Burke is a separate issue from flood zones; the National Wetlands Inventory mapper shows mapped wetlands.
Who handles what
Recorded documents for a parcel near Lyndon Center are with the town clerk, often with an online index. Questions about what you can build around Winooski River need the planning or permitting office, and the answer depends on jurisdiction.
What the zone letters mean
With a lot near Lamoille River, A and V zones are Special Flood Hazard Areas, meaning a 1% or greater chance of flooding each year. For land near East Burke, shaded Zone X marks moderate flood hazard, roughly the 100- to 500-year range; unshaded X is minimal risk.
Parcel lines plus flood zones
FEMA doesn't draw property lines, so pair it with the Vermont Parcel Viewer to see exactly which lot near Connecticut River you're looking at.

A tract near the line by Winooski River may show up across two assessors' files, so check the adjacent map too. For a parcel near St. Johnsbury, our state page lists every bordering county map for Vermont.
Money questions tied to the zone
If a building sits in a Special Flood Hazard Area and the loan is federally backed or regulated, mandatory purchase rules apply where the community participates in the National Flood Insurance Program, whether the land is near Connecticut River or elsewhere in the county. Remodeling a house in a zone near Groton usually means extra permit review; call the permitting office early.
On site with the map
Most viewers work in a phone browser, which helps when you're standing on land near Lamoille River, though signal can drop in rural spots. A saved image of the lot near Hardwick and its lines is a good backup.
