The percentage above counts all developed land, including lawns, parks and roads, not just homes.

Groundwater. At 3,274 of the 3,850 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 576 measured deeper are the exception.
15 addresses fall where the groundwater map has no reading.

Why water gets into Patchogue homes
Patchogue's flood zone follows the Patchogue River and the bay front, where homes damaged by Sandy were bought through the state's NY Rising program. Water reaches Patchogue homes from outside and from within. From outside, it is flooding. Inside the house, the risks are a cesspool backing up, water rising through the basement floor, a pipe that freezes and splits and an aging pipe giving way.
- Water coming in from outside. Floodwater can carry sewage and fuel oil, so treat everything it touched as contaminated and keep children away until it has been cleaned. About 19.4% of Patchogue's built-up land is in FEMA's flood zone, where a home has at least a 1-in-100 chance of flooding in any year. Since 1978, policyholders in ZIP 11772 have filed 824 federal flood insurance claims, a record of flood water reaching buildings in this ZIP. Look up your street. Storm Damage Restoration help
- Sewage coming up a drain. Keep children and pets away from sewage, and stop running water in the house until the line is clear, because every flush adds to what comes up. Part of Patchogue is on public sewer and part still runs on cesspools, so a sewage backup can start in either, and both end in the lowest drain of the house. Only about 18% of Patchogue's built-up land is on public sewer, so whether a backup is a cesspool problem or a sewer-line problem depends on which side of the district line you are on. Cesspool Overflow help in Patchogue
- 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 10 ft below the yard in Patchogue, close enough to seep up through a basement floor after heavy rain or in a high-water season. Basement Flooding help in Patchogue
- A burst pipe. If a pipe bursts, shut the main water valve first; a split supply line keeps running at full pressure until someone does. In a hard freeze the pipes that split are the ones in outside walls and crawlspaces, and Patchogue's houses, about 62 years old on average, have plenty of them. Frozen Pipe Burst help in Patchogue
- 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 Patchogue'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.
