Overview
About half of Lyndhurst's land area sits inside the FEMA 1 per cent annual chance flood zone, and the township is bracketed by two rivers that are both tidal where they pass it — the Hackensack to the east and the Passaic to the west. That geography produces a specific and widely misunderstood situation: a meaningful share of flood water in Lyndhurst is pushed inland by tide and wind rather than dropped by a storm. It can arrive when local rainfall has been unremarkable, and it can keep arriving on the next high tide after the weather has cleared. Getting this distinction right in the first hour changes almost everything downstream. Tidal and river water entering a building from outside is flood water, which a standard homeowners policy does not cover and a separate NFIP or private flood policy does; it is also treated as contaminated, which changes what can be dried and kept and what has to be removed. Water from a failed supply line or water heater inside the building is a different category, usually a covered peril, and usually a smaller job. The federal record gives some sense of scale here: FEMA paid roughly $1.70 million in Individual Assistance to owner-occupants in Lyndhurst after Hurricane Sandy, the third-highest total of any municipality in Bergen County, and the township's ZIP code carries 519 NFIP claims over the life of the programme. Longer-term, the US Army Corps has proposed a 1,900-foot floodgate across the Hackensack at the Secaucus-Kearny line that would shield Lyndhurst and the communities upriver — but it is unfunded and not scheduled to start before 2030, so nothing about it changes what you should do this season.
What comes up most here
- Water arriving without much rain
- If water is rising outside and the rainfall has been moderate, look at the tide rather than the sky. Tidal flooding up the Hackensack and Passaic can put water into low-lying Lyndhurst on a day the storm itself was unremarkable, and it can return on the next high tide.
- Flood water treated as clean water
- River and tidal water is not clean water, whatever it looks like. It carries whatever the channel and the street carried, so porous materials it has soaked — carpet, pad, insulation, most drywall below the line — generally come out rather than being dried in place.
- A homeowners policy assumed to cover it
- Standard homeowners policies exclude flood. If the water came in from outside at ground level, the policy that responds is a flood policy, which is separate and has its own waiting period. This is worth establishing before you authorise work, not after.
- Mid-century basements finished later
- A median build year of 1956 across the township means a great many basements built as utility space and finished decades afterward. Water that once meant a wet slab now means soaked finish, wet insulation inside stud bays, and a job that has to open the finish to dry the structure behind it.
Local context
Lyndhurst is a township in the southern end of Bergen County with roughly 9,704 housing units at a median build year of 1956, and about 50.9 per cent of its land area inside the FEMA 1 per cent annual chance flood zone — half the township. It sits between the Hackensack River to the east and the Passaic to the west, and both are tidal at this point, which is the single most important thing to understand about water here: a significant part of Lyndhurst's flood risk arrives with the tide and the wind rather than with rainfall on the day. Federal records bear that out. FEMA paid roughly $1.70 million in Individual Assistance to owner-occupants in Lyndhurst after Hurricane Sandy, the third-highest total of any Bergen County municipality, and the ZIP code carries 519 NFIP claims across the life of the programme, 149 of them from 2012 alone. The Army Corps has proposed a 1,900-foot floodgate across the Hackensack at the Secaucus-Kearny line that would shield Lyndhurst and the communities upriver; it is unfunded and not scheduled to begin before 2030.

Common questions
How do I tell tidal flooding from a plumbing failure?
Three quick checks. Is the water arriving from outside the building at ground level, or appearing at a fixture, appliance or wall inside? Does it rise and fall over hours rather than running continuously? And does shutting the main stop it? Outside, tidal and unaffected by the main shut-off points to flood water; inside, continuous and stopped by the main points to a supply failure.
Does the proposed Hackensack floodgate change anything for me now?
No. The Army Corps proposal that would protect Lyndhurst and communities upriver is unfunded and not scheduled to begin construction before 2030. It is worth knowing about when thinking about the next decade, and worth ignoring entirely when deciding what to do about water in your building this week.
Is there a provider listed for Lyndhurst?
Provider listings on this site appear only where we have verified a company’s coverage area and registration.
