Flood risk: HighFlood zone. 83 of the 1,010 addresses here are inside FEMA's mapped flood zone. 109 more are within about 100 ft of its edge.
If your home is in it, most mortgage lenders must require flood insurance. That is a separate policy from homeowner's insurance, which usually covers a burst pipe or leaking appliance.
The percentage above counts all developed land, including lawns, parks and roads, not just homes.
Each square is about 250 ft across. Color shows how many of its addresses are mapped inside the zone:

Groundwater. At 890 of the 1,007 addresses measured here, groundwater is within 14 ft of the surface, close enough to reach a basement floor.
In those basements, water can seep up through the floor and come back after pumping until the ground drains. The 117 measured deeper are the exception.
3 addresses fall where the groundwater map has no reading.
Each square is about 250 ft across. Color shows the typical depth under its addresses (USGS map, spring 2013):

Why water gets into Greenport homes
Water reaches Greenport homes from outside and from within. From outside, storm surge can push into streets and ground floors. Inside the house, the risks are a sewer line backing up, groundwater coming up into the basement, pipes bursting in the cold and an aging pipe giving way.
- Water coming in from outside. Storm floodwater can carry sewage and chemicals, so drywall, insulation and flooring it soaked usually have to be cut out and replaced, not just dried. Storm surge is the biggest water threat in Greenport, where a hurricane or a hard nor'easter can drive water from Greenport Harbor into streets and ground floors, and 9.6% of its built-up land is in FEMA's flood zone. Look up your street. Storm Damage Restoration help
- Sewage coming up a drain. Anything porous the sewage reaches, such as carpet or drywall, usually has to come out, and what stays has to be disinfected before it is dried. Greenport is on public sewer, which means sewage in the house comes from a blocked house line or a street main pushing back, and either way the cleanup is the same: remove, disinfect, dry. Sewage Backup help in Greenport
- Water in the basement. Homeowners policies usually exclude groundwater seeping in, so photograph the damage and read your policy before the cleanup starts. Groundwater sits about 11 ft below the yard in Greenport, close enough to seep up through a basement floor after heavy rain or in a high-water season. Basement Flooding help in Greenport
- A burst pipe. With about 18% of its homes empty outside the season, Greenport is a place where a burst pipe can run unnoticed for days, which is why shutting off the water and leaving the heat at 55°F matters before winter. Frozen Pipe Burst help in Greenport
- A leak in a wall or ceiling. Mold can start on wet drywall within a day or two, so a slow leak needs the wall opened and dried, not just the pipe fixed. More than half of Greenport's houses predate 1970, so many still have original supply and drain lines, where a slow leak can run behind a wall for weeks before it shows.

What we do not know about Greenport
- Greenport operates its own village sewer plant (confirmed via its EPA NPDES discharge permit), but the county district layer this site otherwise measures coverage from does not carry village-owned systems, so what share of the village that plant actually serves is not published anywhere we can verify. We do not show a coverage figure rather than estimate one. Check with the village directly for served-area detail.
