Flooding in Saddle River, New Jersey: the flood zone, the record, and what to do
The Borough of Saddle River shares its name with the river that runs through it, but here the river is still small, only a few miles below where it forms. The flood record is short in absolute terms and surprisingly heavy for a borough of fewer than 1,500 homes.
Bergen County's 2026 hazard mitigation plan puts 6.14 per cent of the Borough of Saddle River's land in the FEMA one per cent annual chance flood zone. FEMA's National Flood Insurance Program records 92 claims in the borough and lists eight repetitive-loss properties. Relative to its size, that is more than Mahwah or Upper Saddle River, and Hurricane Ida in 2021 stands out in the record. The river between the upstream gauge in Upper Saddle River and the next gauge in Ridgewood roughly doubles its catchment, and the borough has long kept some of its floodplain as open land.
The short version
- Bergen County's 2026 hazard mitigation plan puts 6.14 per cent of the borough's land in the one per cent annual chance flood zone.
- FEMA records 92 NFIP claims in the Borough of Saddle River, about 61 per 1,000 homes, and eight repetitive-loss properties.
- Hurricane Ida produced 14 claims, nearly as many as Floyd's 17.
- The river roughly doubles its catchment between the Upper Saddle River and Ridgewood gauges.
- FEMA notes the borough has bought flood hazard land for recreation.
The flood zone and the claims
Table 4.6-1 of the Bergen County 2026 hazard mitigation plan measures 195 acres of the borough, 6.14 per cent of its land, inside the one per cent annual chance flood zone, and 6.61 per cent once the 0.2 per cent zone is added. FEMA counts 92 NFIP claims in the Borough of Saddle River over the life of the programme. The US Census Bureau records 1,499 housing units, so by our arithmetic that is about 61 claims for every 1,000 homes, nearly three times the rate in Upper Saddle River upstream. FEMA's multiple-loss records, as of 2 August 2026, list eight repetitive-loss properties, three of them severe repetitive loss. With few homes overall, a handful of riverside properties that flood again and again can account for a large share of the total.
Floyd, Ida and Irene
The borough's worst year in the FEMA data was 2011, with 27 claims, followed by 1999 with 17, 2021 with 14 and 1979 with 6. By named event FEMA attributes 17 claims to Hurricane Floyd, 14 to Hurricane Ida, 11 to Hurricane Irene and 4 to the April 2007 nor'easter. Ida is the unusual entry. In every other Saddle River town from Upper Saddle River down to Lodi, FEMA records fewer Ida claims than either Floyd or Irene claims; here Ida outnumbered Irene and nearly matched Floyd. Ida's remnants on 1 September 2021 dropped extreme rain in a few hours, and the USGS gauge just upstream in Upper Saddle River recorded 3,800 cubic feet per second, the third highest peak there since 1966, behind Floyd's 6,290 and November 1977. On a small, steep river, a short, violent storm can do as much as a long one.
A river still gathering itself
At the USGS gauge on Lake Street in Upper Saddle River, the Saddle River drains 10.9 square miles. By the gauge on Route 17 in Ridgewood it drains 21.6. The Borough of Saddle River lies along that stretch, on a river that is still small enough to rise and fall quickly. Floods here are typically measured in hours, which leaves little warning. FEMA's flood study records that the borough, like Rochelle Park and Ridgewood further down, has bought land within flood hazard areas for recreational use, keeping part of the floodplain free of buildings.
What the borough is doing now
The county's 2026 mitigation strategy summarises the borough's approach briefly. Saddle River has prioritised critical buildings, recently completing a generator for the Municipal Building, and continues to identify infrastructure that could be improved to reduce the chance of failures. The county plan also counts 26 active flood insurance policies in the borough as of October 2024, which is a small number set against eight repetitive-loss properties and 92 past claims.
What this means if you own or rent here
If your property is near the river or a brook feeding it, check the FEMA Flood Map Service Center and ask whether past flood claims are on record for the house before you buy. Because floods here come on quickly, the useful preparation is done in advance: move valuables and equipment out of the basement or up off the floor, keep a battery-backed sump pump, and know a route out that does not cross a low bridge or road by the river. Never drive into moving water. Flood is excluded from homeowners and renters policies and needs a separate flood policy, which normally takes 30 days to start. Groundwater seepage and sewer backup are treated differently again. Whether a particular loss is covered is decided by your insurer and policy wording. About one household in six rents here; tenants need contents cover of their own.
Common questions
Does Saddle River, NJ flood?
Along the river, in big storms. FEMA records 92 flood insurance claims in the borough, with the most in 2011, 1999 and 2021. Most of the borough is outside the flood zone, which covers 6.14 per cent of its land.
Why was Ida so damaging in Saddle River?
Ida dropped very heavy rain in a few hours on a small, quick-rising river. The USGS gauge just upstream recorded its third highest flow since 1966, and FEMA attributes 14 Saddle River claims to the storm.
Is the Borough of Saddle River the same as the Saddle River flooding in Lodi?
Same river, very different scale. The borough is near the headwaters, where the river drains roughly 11 to 22 square miles. By Lodi it drains about 55 square miles, which is why flooding there is longer and broader.
