Flooding in Edgewater, New Jersey: the flood zone, the record, and what to do
Edgewater is a long, thin strip of land squeezed between the Palisades cliffs and the Hudson. Everything below the cliff is close to tide level, and that single fact explains most of the borough's flood record.
The Bergen County hazard mitigation plan puts 49 per cent of Edgewater's land in the 1 per cent annual chance flood zone, and it singles Edgewater out as the one Hudson River municipality in the county where surge flooding is extensive. FEMA records 112 flood insurance claims in the borough, 49 of them from Hurricane Sandy, yet Edgewater carries more active flood policies than any other Bergen community. A second, smaller problem comes from the other direction: rain running off the plateau above the cliffs and backing up at outfalls along River Road.
The short version
- The county hazard plan puts 49.07 per cent of Edgewater in the 1 per cent flood zone, and 52.73 per cent with the 0.2 per cent zone.
- Edgewater is the one Hudson River town in Bergen County where surge flooding is extensive; it holds 1,610 active flood policies, the most in the county.
- FEMA records 112 flood claims, 49 of them from Sandy, and 5 repetitive-loss properties as of August 2026.
- Sandy put up to six feet of water east of River Road, but mostly reached garages rather than homes.
- Rain from above the Palisades backs up at River Road outfalls, closing the road about 35 times in three years.
Half the borough sits in the flood zone
The Bergen County 2026 Hazard Mitigation Plan counts about 304 of Edgewater's 620 acres, or 49.07 per cent, in FEMA's 1 per cent annual chance Special Flood Hazard Area, and 52.73 per cent once the 0.2 per cent zone is added. The plan notes that along the rest of the New Jersey bank the steep cliffs keep Hudson surge to a thin edge; Edgewater is the exception, because it was built on low, filled waterfront at the foot of the Palisades. A state recovery report from 2016, drawing on preliminary FEMA maps, placed most land east of River Road and south of North Street in the high or moderate flood zone. The county plan also lists 1,610 active National Flood Insurance Program policies in Edgewater as of October 2024, the most of any Bergen County community and roughly one in seven policies county-wide.
What FEMA's claims show
FEMA's National Flood Insurance Program data, grouped by community, count 112 claims in Edgewater over the life of the programme. Hurricane Sandy alone produced 49 of them in 2012. FEMA attributes 15 more to a December nor'easter, 13 to Ida and 7 to the March 2010 nor'easter; by year, 2021 (16 claims) and 1992 (15) follow 2012. FEMA's multiple-loss records, as of 2 August 2026, list 5 repetitive-loss properties in the borough, 2 of them severe repetitive loss. Set beside 1,610 policies, the claim total is low, and the reason is the building stock: the US Census Bureau puts the median year built of Edgewater's 7,872 housing units at 1992, the newest in the county, and much of it is mid- and high-rise construction with parking rather than living space at ground level.
Sandy: six feet of water below River Road
The New Jersey Department of Community Affairs recovery report describes Sandy arriving on an exceptional high tide, with some parts of Edgewater under six feet of water. Many residences east of River Road flooded to four to six feet, but because most buildings there park cars on the first floor, the report says the water generally did not reach living space. It counted about 73 homes with flood damage, none substantially damaged, and about 60 flooded vehicles; one marina closed for good. Fallen trees and power lines on River Road effectively split the borough in two, and Department of Public Works staff in the south could not reach the north for up to ten days. One of the four pump stations lost power and stopped.
Rain from above the cliffs
Not all of Edgewater's flooding is tidal. The state report notes that nearly all non-coastal flooding in the borough is generated outside it, as runoff from the towns on the plateau west of the Palisades drains down into Edgewater. From 2013 to 2015 the police recorded 38 reports of road flooding, and 25 of them were at 880 River Road, where an outfall to the Hudson commonly backs up and overflows into the parking lot and the road. River Road was partly or fully closed about 35 times in three years. The same slopes bring a related hazard: the county plan finds Edgewater has the largest share of landslide-susceptible land in Bergen County, and lists a rockslide that closed Route 5 at Undercliff Avenue for two days in 2010 and an Ida debris flow at the base of the cliff in 2021.
Few ways out, and what the borough plans
Edgewater's only roads west over the Palisades are Route 5, Edgewater Road and Gorge Road, and River Road runs the length of the borough at low level. The state report cites a 2007 hurricane evacuation study that put about 1,737 housing units, then 30.5 per cent of the stock, within reach of tidal flooding in a Category 1 hurricane. The county plan finds 12 of Edgewater's critical facilities, 71 per cent, inside the modelled Category 1 surge zone. In its section of the 2026 plan, the borough says it has worked on drainage and back-up power since 2021 and now aims to update flood mapping for a rising Hudson, upgrade community shelters and improve its emergency alert system.
What this means if you own or rent here
If you live east of River Road, assume your building is in or near the flood zone and confirm it on the FEMA Flood Map Service Center. In an apartment or condominium, the association's master policy and your unit policy cover different things; ask for the master policy summary and read where the line falls before a storm, not after. Cars in ground-level garages are often the most exposed thing you own here; move them uphill when a surge is forecast. Flood is a separate policy from homeowners or renters insurance, and FEMA states a new policy normally takes effect 30 days after purchase. About 60 per cent of Edgewater homes are rented, according to the US Census Bureau. Whether a given loss is covered is decided by your insurer and your policy wording.
Common questions
Does Edgewater, NJ flood?
Yes. Almost half the borough is in the FEMA 1 per cent flood zone, and Sandy flooded parts of it to six feet. FEMA records 112 flood insurance claims in Edgewater. Heavy rain also floods River Road regularly.
Is Edgewater in a flood zone?
Much of it. The Bergen County 2026 Hazard Mitigation Plan puts 49.07 per cent of Edgewater's land in the 1 per cent annual chance flood zone. Land east of River Road is the most exposed. Check your own address on the FEMA Flood Map Service Center.
Why does Edgewater flood when Fort Lee and Cliffside Park mostly do not?
Fort Lee and Cliffside Park sit on top of the Palisades. Edgewater sits at the bottom, on low filled land at the water's edge, so Hudson surge reaches it and rain from the plateau above drains into it.
Do I need flood insurance for an Edgewater apartment?
A renter's or unit owner's policy normally excludes flood, and the building's policy does not cover your belongings. Contents-only flood cover is available to renters. Whether a given loss is covered is decided by your insurer and your policy wording.
