Flooding in Fort Lee, New Jersey: the flood zone, the record, and what to do
Fort Lee stands on top of the Palisades, a ridge of hard volcanic rock that rises straight out of the Hudson. River and tidal flooding barely reach it. That changes what residents should worry about, but it does not make water damage rare.
The Bergen County hazard mitigation plan puts just 0.71 per cent of Fort Lee in the 1 per cent annual chance flood zone, one of the smallest shares in the county, and FEMA's current Flood Insurance Study says the borough had no mapped high-risk flood area at all when it took effect. FEMA has recorded 28 flood insurance claims in a borough of more than 19,000 homes. What floods in Fort Lee is mostly roads and ramps in cloudbursts, the strip of parkland at the foot of the cliffs, and, far more often, the inside of buildings.
The short version
- The county hazard plan puts 0.71 per cent of Fort Lee in the 1 per cent flood zone; FEMA's effective study showed none.
- Mapped flood areas lie at the foot of the cliffs, in Palisades Interstate Park.
- FEMA records 28 flood claims and one repetitive-loss property in a borough of 19,679 homes.
- Recorded problems are ramp and road flooding and rockfalls on Henry Hudson Drive.
- Internal leaks in multi-storey buildings are the more common source of water damage here.
Why so little of Fort Lee floods
The Palisades are the exposed edge of a thick sheet of igneous rock, and Fort Lee is built along its crest and western slope. When the Hudson surges, the cliff face takes it. The Bergen County 2026 Hazard Mitigation Plan says plainly that coastal flooding from Hudson surge is extremely limited along the New Jersey bank because of the steep topography, Edgewater excepted. In Fort Lee the plan places the flood-prone sections at the bottom of the cliffs, in the low areas within Palisades Interstate Park along the river. The nearest mapped creek, Overpeck, lies to the west in Leonia and Palisades Park.
Two maps, two answers
FEMA's Flood Insurance Study for Bergen County states that on its effective date Fort Lee had no Special Flood Hazard Areas, along with Alpine, Cliffside Park, Englewood Cliffs and Teterboro. The county's 2026 plan, working from FEMA's 2024 preliminary and effective maps, now counts about 11 acres, or 0.71 per cent of the borough's 1,606 acres, in the 1 per cent annual chance zone and 0.78 per cent with the 0.2 per cent zone. The plan places those acres at the foot of the cliffs, so the change does not alter the picture for the borough's homes. If you are buying or refinancing, ask which map the lender is using, and check the address yourself on the FEMA Flood Map Service Center, which shows preliminary maps as well as effective ones.
The record: 28 claims
FEMA's National Flood Insurance Program data, grouped by community, count 28 claims in Fort Lee over the life of the programme. They are spread thinly: four each in 2011, 2021 and 2022, three in 1978. FEMA attributes four to Hurricane Irene, four to Ida, one to Sandy and one to the April 2007 nor'easter. Its multiple-loss records list a single repetitive-loss property in the borough as of 2 August 2026. The county plan counts 11 active flood policies in Fort Lee as of October 2024. For a borough that the US Census Bureau puts at 40,067 people and 19,679 housing units, the second-largest housing stock in Bergen County, those numbers are tiny.
What does flood: ramps, roads and the cliff road
The water problems on record in Fort Lee are mostly about getting around. The county plan's storm history notes that during the March 2010 nor'easter the westbound Route 4 ramp at mile marker 10.2 in Fort Lee and the Route 9W ramp were closed by flooding. Heavy rain also loosens the cliff itself: the plan lists a rockfall on Henry Hudson Drive just north of the George Washington Bridge in 1959, a 2007 debris flow near Ross Dock that damaged retaining walls and closed Henry Hudson Drive for a month, and small rockslides along the same road in 2018. Fort Lee is also part of the regional stormwater group that neighbouring Englewood convened in March 2024 after repeated cloudbursts.
What this means if you own or rent here
For most Fort Lee households the realistic water risk is a leak, not a flood: a failed supply line, valve or appliance hose, a shared riser, or a roof or mechanical-room failure in a multi-storey building. Know where your unit's shut-off valve is, and in a co-op or condominium read where the governing documents put the line between the association's responsibility and yours. Underground garages and ground-floor units are the places heavy rain can still reach. About 45 per cent of homes are rented, according to the US Census Bureau, and a landlord's or association's policy does not cover a tenant's belongings. Flood is a separate policy from homeowners or renters insurance. Whether a given loss is covered is decided by your insurer and your policy wording.
