Flood risk: LowFlood zone. None of the 2,192 addresses here is inside FEMA's mapped flood zone or within about 100 ft of it.
Groundwater. At 149 of the 2,192 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. At the other 2,043, water in a basement usually comes in from above.
Each square is about 350 ft across. Color shows the typical depth under its addresses (USGS map, spring 2013):
- Within 10 ft82
- 10 to 14 ft67
- 14 to 25 ft1,731
- Deeper than 25 ft312
Sewer. 23 of the 2,192 addresses in Baywood have a county sewer main mapped past them. That does not mean every house is connected.
At the other 2,169, a backup means a cesspool or septic tank, and a pumping company. On a main, it means a plumber, or the sewer district if the main is blocked.
Each square is about 350 ft across. Color shows how many of its addresses have a mapped main:

Why water gets into Baywood homes
None of Baywood's built-up land is in FEMA's flood zone, so floodwater from outside is not the main threat to homes here. The water damage here starts under and inside the house: a full or failing cesspool, water getting into the basement, a pipe that freezes and splits and old plumbing leaking inside the walls.
- 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. County records map no sewer main past 2,169 of Baywood's 2,192 addresses; those homes run on a cesspool or septic tank, and when one fills or fails, sewage comes back up through the lowest drain in the house. Cesspool Overflow help in Baywood
- Water in the basement. Homeowners policies usually exclude groundwater seeping in, so photograph the damage and read your policy before the cleanup starts. The 21 ft average hides a spread: on some Baywood streets groundwater comes close enough to a basement floor to seep in after a wet spell. Basement Flooding help in Baywood
- 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. Fuel oil heats about 47% of Baywood's homes, so a missed delivery in a cold week can leave a house without heat long enough for a pipe to freeze and split. Frozen Pipe Burst help in Baywood
- A leak in a wall or ceiling. An old shutoff valve can seize, so find the main valve and test that it turns before the day you need it. More than half of Baywood'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.

Homes here
- Sewer status
- Unsewered (Cesspool/Septic)
- Home heating fuel
- 47% fuel oil Utility gas heats 41% of occupied homes in Baywood. 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 1950s band is the largest, at 39%, but its lead over the 1960s band (34%) is inside the Census margin of error (8 points), so no decade clearly leads in Baywood. 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.
