Flooding in Englewood Cliffs, New Jersey: the flood zone, the record, and what to do
If you are wondering whether Englewood Cliffs floods, the short answer from the federal record is no. The longer answer is that heavy rain still finds its way into basements on the ridge, and the cliff below the borough has its own water-driven hazard.
FEMA's National Flood Insurance Program has recorded no flood claims at all in Englewood Cliffs, and no repetitive-loss properties. The Bergen County hazard mitigation plan puts 1.09 per cent of the borough in the 1 per cent annual chance flood zone, and places that sliver at the foot of the Palisades, inside the interstate park along the Hudson. For homeowners on the ridge, the realistic water risks are cloudburst runoff, a failed sump pump and an ageing plumbing system, not river or tidal flooding.
The short version
- FEMA has recorded no flood insurance claims and no repetitive-loss properties in Englewood Cliffs.
- The county hazard plan puts 1.09 per cent of the borough in the 1 per cent flood zone, all at the foot of the cliffs.
- FEMA's effective flood study showed no high-risk flood zone in the borough at all.
- The August 2024 storm that flooded Englewood stalled over Englewood Cliffs too, dropping 5.9 inches.
- Basement seepage, sump pumps and old plumbing are the realistic water risks on the ridge.
Zero claims, honestly reported
FEMA's National Flood Insurance Program data, grouped by community, show no claims in Englewood Cliffs over the life of the programme, and FEMA's multiple-loss records, as of 2 August 2026, list no repetitive-loss properties. That is rare in Bergen County. It does not mean no Englewood Cliffs home has ever taken water, only that no insured flood loss has been filed under the borough's name. The US Census Bureau counts 2,079 housing units in the borough, mostly owner-occupied: only about 16.5 per cent of households rent. The county plan's table of active flood policies does not list the borough, so few homes may be insured for flood at all; the empty record reflects low risk, but also few policies.
Where the 1 per cent sits
FEMA's Flood Insurance Study for Bergen County states that, on its effective date, Englewood Cliffs had no Special Flood Hazard Areas at all. The county's 2026 Hazard Mitigation Plan, using FEMA's 2024 preliminary and effective maps, now counts about 14.5 of the borough's 1,333 acres, or 1.09 per cent, in the 1 per cent annual chance zone and 1.40 per cent including the 0.2 per cent zone. The plan explains where: the flood-prone sections are at the bottom of the cliffs, in the low areas within Palisades Interstate Park beside the Hudson. The borough's homes stand on the ridge, far above the river. Check an individual address on the FEMA Flood Map Service Center if a lender raises the question.
Cloudbursts still reach the ridge
High ground does not stop rain. On 6 August 2024, according to the City of Englewood, a storm cell stalled over Englewood Cliffs and Englewood and dropped 5.9 inches in about three hours. Downhill in Englewood more than 300 people had to be rescued. On the ridge itself a storm of that size can overwhelm gutters, saturate the soil against foundation walls and push water through basement cracks and window wells. Englewood Cliffs is part of the regional flooding and stormwater group Englewood convened in March 2024, and in its section of the 2026 county plan the borough lists improving drainage systems and their maintenance among its completed actions, alongside generators for shelters and back-up power for police, fire and EMS.
The cliff face: water and rock
The other water-related hazard in Englewood Cliffs is on the cliff, not in the houses. The county plan identifies the Palisades as one of the most active landslide areas in New Jersey, with rockfalls and slides concentrated in winter and spring. Its record for the borough includes a 2007 debris flow near Ross Dock that damaged retaining walls and closed Henry Hudson Drive for a month, a 2009 rockslide at the Tenafly border triggered by rain and snowmelt, a debris flow of mud, rock and trees during Tropical Storm Irene in 2011, and a large rockslide in 2016. These affect park roads below the borough rather than homes, but they show what saturated ground does on a steep slope.
What this means if you own or rent here
The things worth doing here are ordinary maintenance rather than flood planning. Keep gutters and downspouts clear and discharging well away from the foundation, and check that the ground slopes away from the house. If the basement has a sump pump, test it each spring and consider a battery backup, because the heaviest storms often bring power cuts. Replace ageing water-heater tanks and washing-machine hoses before they fail; in a house built around 1969, as the median Englewood Cliffs home was, original supply lines may be well past their expected life. Flood is a separate policy from homeowners insurance, and seepage and sewer backup are treated differently again. Whether a given loss is covered is decided by your insurer and your policy wording.
Common questions
Does Englewood Cliffs, NJ flood?
Rarely. FEMA has no record of a flood insurance claim in the borough, and only about 1 per cent of its land, at the foot of the Palisades, is in the mapped 1 per cent flood zone. Heavy rain can still put water in basements.
Is Englewood Cliffs in a flood zone?
Almost none of it. The Bergen County 2026 Hazard Mitigation Plan puts 1.09 per cent of the borough in the 1 per cent annual chance zone, inside Palisades Interstate Park by the river. Residential areas on the ridge are outside it.
Why does my basement take water if the borough does not flood?
Basement water on high ground usually comes from saturated soil against the foundation, roof runoff discharged too close to the wall, or a sump pump that stopped working. It is a drainage and maintenance problem rather than a flood in the insurance sense.
