Land along the creek bottoms near Hingham and the flats outside Bridgewater are where a Plymouth County flood zone map lookup matters most. FEMA's free Flood Map Service Center and the Plymouth County parcel viewer answer it together.
Next: FEMA's search tool, the zone labels you'll see for Plymouth County, and how the parcel record confirms which tract you're on.
Look up the Plymouth County flood zone map step by step
Open the FEMA Flood Map Service Center and type a county street address, say one in Carver. If a property near Duxbury has no street number yet, search the nearest road and pan to it. On acreage outside Carver, FEMA's National Flood Hazard Layer viewer draws the zones over aerial imagery, so you can see if the shading reaches a house near Duxbury. Then open the MassGIS Interactive Property Map for Plymouth County to confirm the parcel near Carver. If the Plymouth County viewer has a floodplain layer, treat it as a convenience copy and confirm on FEMA's map.

Towns and land across Plymouth County
Town lots cluster around Plymouth, the county seat, and Bridgewater, Brockton, Abington, and Carver. Smaller places such as Cedar Crest, Green Harbor, and Hanson appear on the Plymouth County map as little clusters of lots. Roughly 659 square miles of land and about 535,308 residents (2023 estimate) make up Plymouth County. Much of Plymouth County is built out, so most clicks near Carver land on platted lots. Plymouth County was organized in 1685, so deeds for older farms near Abington can run back a long way.
High, moderate and minimal risk in Plymouth County
For a lot in Carver, the label matters more than the color: A and V zones are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any given year (the base or 100-year flood). A surveyor working near Carver uses the base flood elevation printed for AE zones; unnumbered A zones don't have one. Land near Duxbury in shaded X (Zone B on older maps) sits in the moderate band between the 100-year and 500-year floods. Unshaded Zone X near Duxbury is minimal risk.
Tracts that cross the Plymouth County line
Plymouth County borders Barnstable County, Bristol County, Norfolk County, and Suffolk County, and each keeps its own parcel map and records. Our Massachusetts page links each map neighboring Plymouth County.
Where Plymouth County land records are kept
Deeds and plats behind the Plymouth County map are kept by the county's recording office; the official Plymouth County website names which office that is. A deed book and page or instrument number on the county record is the fastest way to request the document for a lot in East Bridgewater.

A low spot on a Plymouth County tract outside any mapped zone, which is why it is worth walking the ground after a heavy rain.
Insurance, permits and map changes
Insurance is the practical stake for a Plymouth County buyer. Where a building in Carver sits in a Special Flood Hazard Area and carries a federally backed mortgage, federal rules call for flood insurance under the Flood Disaster Protection Act, wherever the community joins the NFIP. Outside the A zones around Duxbury, insurance is a choice, not a mandate, although some lenders require it anyway. When a Plymouth County homesite is on a rise inside a mapped zone, a Letter of Map Amendment request is the formal route, supported by elevation data from a licensed surveyor. Placing fill on low ground near Carver frequently requires a permit and an elevation check, so call the county or the town office in Carver before work starts.
Plymouth County, MA: common questions
Can I build in a flood zone in Plymouth County?
Often, but local floodplain rules apply; ask the county or town building office in Carver well before you buy.
Is Zone AE near East Bridgewater high risk?
Yes, a property near East Bridgewater in Zone AE is high risk: a 1-percent-annual-chance floodplain where FEMA lists a base flood elevation.
My house near East Bridgewater is in Zone X. Is insurance required?
Not under federal rules; Zone X in Plymouth County is outside the Special Flood Hazard Area, though a lender can still require coverage.
Does the Plymouth County parcel map display flood zones?
Check the layer list in the MassGIS Interactive Property Map; if Plymouth County includes a floodplain layer, confirm the zone on FEMA's map anyway.
Can a flood zone in Plymouth County be changed?
For a lot in Carver, hire a surveyor for an elevation certificate, then file a LOMA request with FEMA.
