Reading the zones on a Windham County flood map
On the FIRM covering Windham 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). Zone AE near Brookline means FEMA published a base flood elevation; plain Zone A means no detailed elevation was studied. Land near Brookline in shaded X (Zone B on older maps) falls between the base flood and the 500-year flood. Unshaded Zone X near Brookline is minimal risk.
Windham County land records
Deeds and plats behind the Windham County map are kept by the county's recording office; the official Windham County website names which office that is. A deed book and page or instrument number on the county record is the quickest route to request the document for a lot in Athens.

Flood insurance and building rules in Windham County
Lenders watch the zone closely on Windham County properties. If a house near Brookline falls inside an A or V zone and is financed by a regulated or federally insured lender, federal rules call for flood insurance, as long as Windham County or the town participates in the NFIP. Outside the A zones around Brookline, insurance is a choice, not a mandate; pricing a policy for land near Brookline is still worth a call. If a building near Brookline sits above the flood line, FEMA's LOMA process allows a review, supported by elevation data from a professional surveyor. New construction in a Windham County Special Flood Hazard Area has to meet local floodplain rules, so call the county or the town office in Dover before work starts.
