Flood risk: Very HighFlood zone. 970 of the 3,719 addresses here are inside FEMA's mapped flood zone. 368 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.

- Half or more

Groundwater. At 3,168 of the 3,669 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 501 measured deeper are the exception.
50 addresses fall where the groundwater map has no reading.
Each square is about 400 ft across. Color shows the typical depth under its addresses (USGS map, spring 2013):

Sewer. 3,324 of the 3,719 addresses in Amityville have a county sewer main mapped past them. That does not mean every house is connected.
Where a house is connected, a backup is a blocked line. A plumber clears the pipe to the street. The sewer district clears the main.

Why water gets into Amityville homes
Water reaches Amityville homes from outside and from within. From outside, storm surge can push into streets and ground floors. Inside the house, the risks are a blocked sewer line, groundwater coming up into the basement, pipes bursting in the cold and old plumbing leaking inside the walls.
- Water coming in from outside. After surge water recedes, anything porous it touched (drywall, insulation, carpet) normally comes out, and photos taken before cleanup make the flood claim easier. When a hurricane or a strong nor'easter hits, surge from Great South Bay can reach homes across Amityville, and 29.5% 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. With Amityville on public sewer, roots and grease in the line to the street are a common cause of a backup, and the first place it shows is a basement floor drain or a low toilet. Sewage Backup help in Amityville
- Water in the basement. Groundwater in a basement returns after a pump-out unless a sump pump keeps up, so drying the walls and floor matters as much as removing the water. In Amityville, the water table is about 10 ft down, close enough to push water up through a basement floor, so a basement that has been pumped dry can fill again. Basement Flooding help in Amityville
- A burst pipe. A frozen pipe that has not split yet can be saved: open the tap and warm the line gently from the tap end back, never with a flame. Pipes in outside walls, crawlspaces and unheated garages freeze first, and in Amityville's homes, about 67 years old on average, much of that plumbing predates modern insulation. Frozen Pipe Burst help in Amityville
- A leak in a wall or ceiling. To check for a hidden leak, turn off every tap and watch the water meter; if it still moves, water is going somewhere it should not. With 62% of its homes built before 1970, Amityville has a lot of original plumbing, and an old pipe tends to fail slowly, as a stain or a soft floor, before it fails all at once.

- 20% fuel oil Utility gas heats 62% of occupied homes in Amityville. Census estimates; the oil figure is within 8 points. An oil tank can float or tip in a flood and spill. That is a separate cleanup from the water (NYS DEC). In a cold snap, an empty tank means no heat.
- When homes were built
- Spread across decades The highlighted before-1940 band is the largest, at 23%, but its lead over the 1950s band (18%) is inside the Census margin of error (6 points), so no decade clearly leads in Amityville. Most homes here are over 30 years old. Past that age, an insurance-industry study (IBHS) found supply and drain pipe problems three times as likely.
