Weighing a property around Everett? Checking the Cambridge flood zone map reveals whether it sits in a FEMA flood zone, and the lookup is free. In this Cambridge guide: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the MassGIS Interactive Property Map.
The Cambridge flood zone map: start here
Start with FEMA's Flood Map Service Center: type an address near Everett, then open the map view for that panel. Rural land near Medford with no street number is still easy to locate: pan from the closest town and click the spot.
Getting to the right map
Your first stop is the MassGIS Interactive Property Map; it includes each tax parcel around Everett and Somerville. Without an address in hand, zoom in from Arlington and select the outline. For a tract near Malden, the record panel normally shows the owner of record, assessed acreage, the parcel number and often a sale date.
Where Cambridge fits in
Cambridge lies within Middlesex County, Massachusetts, which means parcel data comes from the county. Cambridge is also the county seat, which puts the Registry of Deeds close by. If you're looking near Arlington, the municipality handles things like zoning, permits and utilities within town limits, but the county runs assessment and recording. Land beyond the city limits toward Everett often answers to county rules, not municipal ones.
What to request from a seller
Ask the listing agent about past flood claims for the house near Everett; getting a quote early avoids surprises.
What the zone letters mean
Zone AE carries a published BFE, which plain A zones lack; builders around Malden design to it. For a parcel near Belmont, shaded Zone X is moderate risk, between the 1% and 0.2% annual chance floods; plain X, or C on older maps, is minimal risk.
Matching the zone to the lot lines
FEMA doesn't draw property lines, so check the MassGIS Interactive Property Map too for the outline of the tract near Malden.
Low spots and local drainage
Small streams around Belmont may not have detailed mapping, so walk the land after rain. Wetlands near Somerville can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
Where the recorded documents are
The map is an index, not the title: deeds, subdivision plats and easements covering ground around Medford are filed with the Registry of Deeds. Older tracts around Arlington can go back through many deeds, so a title company can sort it out if money is changing hands.
Sections, lots and bearings
Rural deeds near Medford commonly use metes-and-bounds descriptions, a series of courses and distances from a starting point. Town lots near Arlington usually use lot and block from a recorded plat instead, which is simpler to follow. Copy the legal description from the record for the parcel near Everett for any title or survey request.
Land on the county line
Middlesex County touches Essex County, Norfolk County, Suffolk County, Worcester County, and Hillsborough County, NH; every one of them runs a separate parcel map. Acreage along the edge near Medford may show up in two county records, so check the adjacent map too. For property near Malden, the Platbookmapper state page links every neighboring county map across Massachusetts.
Using it on a phone
Most viewers work in a phone browser, handy when you're parked on a road near Belmont, so load it before you lose signal. A screenshot of the parcel near Arlington with its ID keeps working without signal.
Insurance, lenders and building
For land near Somerville, get the Elevation Certificate if one exists: it compares the building to the BFE. Building or adding on near Everett in a mapped zone can trigger elevation rules; check with the county or town building office before you plan.
A quick look at the area
Cambridge holds the county offices, which is where the courthouse records live. Smaller places on the map include Somerville, Medford, Belmont, and Arlington. Roughly 1,623,952 people live in Middlesex County (Census estimate, 2023) on about 818 square miles. Middlesex County was formed in 1643, and some chains of title near Medford are long. Places such as Assabet River National Wildlife Refuge make handy reference points on the map near Malden.
Before you lean on the lines
The acreage figure is a tax-roll number; just a licensed surveyor establishes the real corners for a parcel near Malden. On ground around Everett, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Cambridge: common questions
Why did my flood zone near Belmont change?
Good question; a new study can move a zone line near Medford; your community is notified before changes take effect.
Is AE a high-risk flood zone for land near Everett?
It depends, but AE is a Special Flood Hazard Area with a published base flood elevation, which shapes building rules near Somerville.
What is a LOMA around Somerville?
For most people, FEMA's LOMA process is the usual route when a building near Somerville sits above the base flood elevation, and lenders accept the result.
What is a base flood elevation around Belmont?
Usually, a BFE near Belmont tells builders how high the lowest floor should be, and an Elevation Certificate compares the building to it.
How do I save a parcel from the viewer in Cambridge?
