Flooding in Teaneck, New Jersey: the flood zone, the record, and what to do
Teaneck is bounded by water on two sides, the Hackensack River to the west and Overpeck Creek to the east, but most of the township sits on higher ground between them. Its flood record is modest for a town of its size.
The Bergen County 2026 hazard mitigation plan puts 9.80 per cent of Teaneck in the FEMA 1 per cent annual chance flood zone. FEMA counts 112 National Flood Insurance Program claims in the township, spread almost evenly across Irene, the April 2007 nor'easter, Ida and Sandy, and 11 repetitive-loss properties, none in the severe category. For most of Teaneck's mid-century homes, basement water from rain and drains is a more frequent problem than river flooding.
The short version
- The Bergen County 2026 hazard plan maps 9.80 per cent of Teaneck in the 1 per cent annual chance flood zone, along the Hackensack and Overpeck Creek.
- FEMA records 112 flood insurance claims in Teaneck, split almost evenly between Irene, the April 2007 nor'easter, Ida and Sandy.
- FEMA lists 11 repetitive-loss properties and no severe repetitive loss properties, as of August 2026.
- FEMA does not credit the Overpeck Creek channel from Route 4 to West Forest Avenue with protecting against the 1 per cent flood.
A modest record for a big township
FEMA's OpenFEMA data list 112 National Flood Insurance Program claims for Teaneck Township. The US Census Bureau counts 14,060 housing units, so the record works out at under one claim for every hundred homes over the life of the programme. The claims cluster in four years, each tied to a different kind of storm: 2011 with 18, the same number FEMA ties to Hurricane Irene; 2007 with 17, 15 of them from the April nor'easter; 2021 with 17, 14 from Ida; and 2012 with 12, 11 from Sandy. FEMA's multiple-loss records, as of 2 August 2026, list 11 repetitive-loss properties in Teaneck and no severe repetitive loss properties. That even spread across rain floods, a downpour and a surge is itself useful: there is no single type of event that Teaneck residents can watch for and ignore the rest.
Where the flood zone lies
Table 4.6-1 of the county hazard plan counts 391.37 of Teaneck's 3,993.66 acres in the 1 per cent annual chance flood zone, which is 9.80 per cent, rising to 10.81 per cent with the 0.2 per cent zone. The zone sits along the township's edges. To the west is the tidal Hackensack River; the county plan lists portions of Teaneck among the municipalities exposed to coastal surge on the river. To the east is Overpeck Creek and its tributary Teaneck Creek, much of whose floodplain is park and conservation land; the county plan mentions the Teaneck Creek Conservancy among the floodplain forests along the county's waterways. The central ridge of the township is outside the mapped zone.
Overpeck Creek and the walled channel
FEMA's Flood Insurance Study for Bergen County records a flood control project on Overpeck Creek in Englewood and Teaneck, from State Route 4 to West Forest Avenue. It consists of a straightened channel with concrete retaining walls, originally designed to contain the 1 per cent annual chance flood. The study is careful about what it does now: it provides limited protection from frequent floods, it is not shown on the maps as protecting against the 1 per cent flood, and while flooding along Route 4 has been reduced, flooding along West Forest Avenue can still be a problem. Downstream, the creek's level is set partly by tide gates at the New Jersey Turnpike. FEMA gives Overpeck Creek a drainage area of 12.0 square miles just above its confluence with Teaneck Creek and puts the 1 per cent stillwater elevation at that confluence at 5.7 feet above the NAVD88 datum. Teaneck's own flood study rests on work completed in November 1979.
The river side
FEMA's study states that the principal flooding in southern Bergen County results from the tidal stages of Newark Bay acting on the Hackensack and its creeks. For Teaneck's western edge that means the river can rise with a surge or a long nor'easter as well as with heavy rain upstream. The nearest National Weather Service forecast point is the tidal gauge Hackensack River at Hackensack, which reaches minor flooding at 7.8 feet above mean lower low water. The county mitigation strategy records that Teaneck plans to extend its warning siren and speaker system, and to hold more public meetings to brief residents and the people in charge of what it calls life hazard use facilities.
What this means if you own or rent here
Check your address on the FEMA Flood Map Service Center; with the zone confined to the edges, most addresses are outside it. If you are near the river or the Overpeck, keep an eye on coastal flood forecasts and tide times as well as rainfall, and do not assume the concrete channel protects you. For everyone else, the township's housing is the bigger factor. The US Census Bureau puts the median year built at 1950, which means many basements predate modern waterproofing and many have been finished since. Keep downspouts discharging away from the walls, test the sump pump before storm season, and ask a licensed plumber about a backwater valve. About 22.5 per cent of households rent; tenants need their own contents cover. A flood policy is separate from homeowners insurance and normally takes 30 days to start, and whether a loss is covered is decided by your insurer and your policy.
Common questions
Does Teaneck, NJ flood?
Its edges do. About a tenth of the township is in the FEMA 1 per cent annual chance flood zone, along the Hackensack River and Overpeck Creek, and FEMA counts 112 flood insurance claims there. The centre of the township is on higher ground.
Is Teaneck in a flood zone?
Part of it. The county hazard plan puts 9.80 per cent of Teaneck's land in the 1 per cent annual chance zone and 10.81 per cent including the 0.2 per cent zone. Whether a particular address is in the zone is shown on the FEMA Flood Map Service Center.
Does the Overpeck Creek flood wall protect Teaneck?
Only partly. FEMA's flood study says the channel and concrete walls from Route 4 to West Forest Avenue give limited protection against frequent floods and are not shown as protecting against the 1 per cent annual chance flood.
