Before you buy or build near Hingham, pull up the Brockton flood zone map: the zone on that map shapes insurance, permits and resale. What this Brockton guide covers: finding the address on FEMA's map, decoding A, AE and X, and confirming the outline on the county map.
The Brockton flood zone map: start here
The official source is FEMA's Flood Map Service Center: type an address near Marshfield, and choose the dynamic map. A tract near Scituate without an address can still be found: zoom in from Interstate 495 and click the spot.
Pulling up a parcel
Go first to the MassGIS Interactive Property Map; it covers every tax parcel in the county, Scituate included. In and around Scituate, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. Out toward Scituate, the record panel typically gives the owner of record, assessed acreage, a parcel ID and sometimes recent sales.
Brockton, MA: the basics
Brockton lies within Plymouth County, Massachusetts, so its parcels are on the county's map. For property near Hingham, city or town hall handles matters such as zoning, permits and utilities within town limits, while the county keeps the tax map. Lots just outside the town limits out by Hingham generally falls under county rules instead.
What the zone letters mean
An AE label comes with a base flood elevation, and an unnumbered A zone has none; that elevation drives building rules near Kingston. Closer to Abington, shaded Zone X marks moderate flood hazard, between the 1% and 0.2% annual chance floods; unshaded X is minimal risk.
Backing up the map with records
The map is an index, not the title: recorded deeds, plats and easements covering ground around Kingston sit with the Registry of Deeds. For acreage around Abington, have ready the book and page listed on the parcel record so staff can find the deed fast.
Parcel lines plus flood zones
FEMA's map shows zones but not ownership, so check the MassGIS Interactive Property Map too to confirm you have the right parcel near Hingham.
Plymouth County in a few facts
Plymouth serves as the county seat, home to the main records offices. You'll also find Abington, Hanson, Hingham, and Scituate, each with its own cluster of lots. Around 535,308 people live in Plymouth County (Census estimate, 2023) on roughly 659 square miles. Plymouth County was organized in 1685, and some chains of title near Kingston are long. Places such as Boston Harbor Islands National Recreation Area help you orient on the aerial around Hingham.
Limits of the parcel data
Tax maps are drawn for assessment, not surveyed, so a fence near Scituate may sit some distance off the line on screen. With a lot near Hanson, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Money questions tied to the zone
If you're looking near Scituate, get the Elevation Certificate if one exists: it compares the building to the BFE. Building or adding on near Abington in a mapped zone usually means extra permit review; call the permitting office before you plan.
On site with the map
Most viewers work in a phone browser, which helps when you're standing on land near Scituate, so load it before you lose signal. A saved image of the lot near Scituate and its lines keeps working without signal.
Who handles what
If the acreage or value on a parcel near Hanson looks off are handled by the town assessor, which maintains the tax roll. Building or septic questions for a lot near Hanson go to planning, building or health offices, and the answer depends on jurisdiction.
A short flood checklist
Ask the seller for any Elevation Certificate for the house near Abington; an insurance quote early keeps the budget honest.
Low spots and local drainage
Creeks and ditches near Abington may not have detailed mapping, so look for water marks and debris lines. Wetlands near Kingston can limit building even outside a flood zone; check the National Wetlands Inventory mapper for a first look.
Sections, lots and bearings
Tracts outside towns near Hanson are often described by metes and bounds, which trace the boundary call by call. Town lots near Hanson are typically described by lot and block, which is simpler to follow. Copy the legal description from the record for the parcel near Marshfield when you talk to a surveyor.

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.
