Flood risk: MediumFlood zone. 11 of the 1,814 addresses here are inside FEMA's mapped flood zone. 72 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.

Groundwater. At 1,809 of the 1,814 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 5 measured deeper are the exception.
Each square is about 400 ft across. Color shows the typical depth under its addresses (USGS map, spring 2013):

Why water gets into West Bay Shore homes
In West Bay Shore, flooding is the outside risk, and inside the house the risks are water rising through the basement floor, a blocked sewer line, a pipe that freezes and splits and old plumbing leaking inside the walls.
- Water coming in from outside. Standard homeowners insurance does not cover floodwater, so if the water came in from outside it is your flood policy that pays; take photos before anything is moved. FEMA's flood zone covers about 3.8% of West Bay Shore's built-up land, and homes on those streets with a federally backed mortgage must carry flood insurance. Since 1978, ZIP 11706 has logged 2,044 federal flood insurance claims, so flood water has reached buildings in this ZIP before. Look up your street. Storm Damage Restoration help
- 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 West Bay Shore, the water table is about 8 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 West Bay Shore
- Sewage coming up a drain. A sewage cleanup runs in a set order: remove the water and whatever it soaked, disinfect, then dry; skipping a step leaves bacteria in the floor and walls. Homes in West Bay Shore are on public sewer, so a backup usually starts in the line between the house and the street, or in a main that overloads in heavy rain; a backwater valve keeps the second out. Sewage Backup help in West Bay Shore
- 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 West Bay Shore's homes, about 64 years old on average, much of that plumbing predates modern insulation. Frozen Pipe Burst help in West Bay Shore
- A leak in a wall or ceiling. A leak caught early is a drying job; one that has run for weeks inside a wall is a mold job, so have it opened up and dried properly. About 65% of West Bay Shore's homes were built before 1970, and pipes from that era, galvanized steel and cast iron, corrode from the inside until a joint or a section gives way.
