Water Damage Restoration in Little Falls, NJ
Two rivers reach this township, and only one of them has a gauge that tells you which street goes first. Water out, structure dried, mold remediated, and the building put back by the crews who did the drying.
Most flood writing about Little Falls is about the Peckman, and it should be: the Peckman is the stream that puts water into the low blocks fastest, and what it does to a basement window and a cellar wall is covered on our Little Falls windows and glass page. This page is about the other one. The Passaic main stem is gauged here as well, and that gauge — LTFN4 to the Weather Service, 01389500 to the US Geological Survey — publishes thirteen separate impact statements and a crest list going back to 1903.
Thirteen is a lot. Most New Jersey river gauges publish three or four, and several publish none at all. What thirteen buys you is a ladder: a set of readings, each attached in plain language to the roads and houses that go under at that height, so that a number on a screen becomes a decision in a hallway.
Behind the ladder is a claim file. FEMA has 1,905 National Flood Insurance Program claims on record for this township, dates of loss from 1978 to 2024, of which 1,660 were closed with a payment on the building, on contents, or on both — $40.2 million in all. That is not a count of buildings that flooded. It is a count of times an insured building flooded, and a building with no flood policy is not in the file at all.
What we do
- Water extraction and structural drying — our own crews, not a dispatch network
- Mold remediation — remediation of what the water left behind
- Sewage and flood cleanup — water that came up through a sewer or across the ground
- Rebuild after the damage — the same company puts the building back
- All 21 New Jersey counties — the shop and the crews are in Garfield, Bergen County
- Paid by insurance or by you — we document the loss and the work; we do not handle the claim
Thirteen statements, and the one that names your road
The Weather Service sets this gauge's action stage at 6.5 feet, minor flooding at 7, moderate at 8 and major at 9. Those are the categories. The impact statements are the useful part, and they are written in road names rather than in hydrology.
At 6.5 feet: "Low lying areas in the vicinity of Two Bridges in Wayne are flooded. The lower end of Bergen Street in Paterson, closest to the river, begins to flood." At 9.5 feet, half a foot into the major category, the text turns to this township: "Route 46 in Wayne is subject to closures. Riverside Drive in Wayne floods. Flooding in Little Falls worsens as homes on William Street and Zeliff Avenue take on water." At 10 feet Wagaraw Road in Hawthorne closes and water begins to flow over the Temple Street bridge in Paterson. At 10.5 feet the businesses along Route 46 in Wayne begin to flood and Route 23 goes under. At 12 feet: "Wagaraw Road in Hawthorne, between Lafayette Avenue and Lincoln Avenue, is closed. Passaic Avenue, Schoon Avenue and Vincent Street are also closed. Homes and businesses flood."
Two things follow from reading that ladder rather than a rainfall forecast. The first is that the thirteen statements for this gauge between them name six municipalities — Hawthorne, Paterson, Wayne, Little Falls, Lincoln Park and Fairfield — because the river does not stop at a border — the reading that matters to a house here is the same reading that matters to a house in Wayne, and the two towns are busy on the same night. The second is that the gauge carries a standing note from the Weather Service: "Gauge reading affected by reservoir operations." The number is real, and it is not purely a measure of how much rain fell.
The crest list under it runs to 48 entries. The tallest, 17.5 feet on 10 October 1903, is flagged as an old-datum reading and should not be set beside the modern ones as though it were the same measurement. On the current datum the record is 14.19 feet on 30 August 2011, at 20,800 cubic feet per second — Hurricane Irene — with 12.91 feet in the April 1984 flood behind it.
The storm this township remembers is not the storm that filled its file
Hurricane Floyd is the flood Little Falls tells stories about, and the rainfall record behind those stories is real. The claim file disagrees about the consequences. Floyd accounts for 116 claims here. Hurricane Irene accounts for 309 — nearly three times as many — and 2011 is by a wide margin the worst year in the record at 588 claims, more than double any other year.
Below Irene the list is not made of hurricanes at all. The March 2010 nor'easter produced 235 claims, the April 2007 nor'easter 231, and 229 more are filed under FEMA's unnamed label, simply "Flooding". Another 196 sit under "Late winter storms". Add those four together and you get 891 claims — 47 percent of everything on record here — from weather nobody gave a name to.
That is the single most useful thing in this township's data, and it cuts against how people plan. A storm with a name arrives with three days of warning, a full news cycle and a reason to move the contents of the basement upstairs. Late winter storms arrive on a Tuesday. On these numbers the unnamed weather has done roughly as much damage here as the named weather, and it is the kind nobody prepares for.

| Built in 1939 or earlier | 1,281 (22.0%) | Same table |
Why the first row is not a count of flooded buildings. FEMA's claims file records insured buildings only, and one building that has flooded four times appears four times. Read it as a measure of how often water has got into insured property here, not as a census of addresses. The basement rows are counted on FEMA's published code list — 0 none, 1 finished basement or enclosure, 2 unfinished, 3 crawlspace, 4 subgrade crawlspace — and the 541 blanks are shown rather than quietly dropped, because dropping them would push the basement share to a number the file does not support.
A hundred and eighty-four properties, and two different answers
FEMA's hazard-mitigation record for this township holds 184 properties. A hundred and two of them were bought and demolished. Eighty-one were raised. One was floodproofed in place.
That near-even split between demolition and elevation is unusual, and it matters for anybody standing in a wet building here, because the two answers leave behind two completely different buildings. A bought-out lot is gone; the water now goes where the house used to be, which changes what the neighbours get. A raised house is still a house, and the living space has been lifted above a design flood elevation while whatever sits underneath it — the slab, the piers, the utilities, the parking — has been given up to the water on purpose.
Under a raised house there is usually no finished floor to save and nothing porous that is supposed to stay dry, so the work is short and the answer is obvious. It is the mechanical equipment that decides the day: a furnace, a water heater, an electrical panel or an air-handler that has been submerged is not a drying problem, and putting a wet unit back into service is the one shortcut that turns a flood into a second event weeks later.
The unraised, unbought majority is where the real work is. 1,321 of the coded claims here are on a building with a basement, an enclosure or a subgrade crawlspace, and 322 of those basements were finished — carpet, pad, insulated stud walls, base trim, sometimes a bathroom. Eighty percent of this township's housing was built before 1980 and 22 percent before 1940, which is old enough that the rules governing what may be torn out and how are a live question rather than a formality. Those rules do not vary from one municipality to the next, and they are written out in full one level up.
What a Little Falls cellar hands a crew
Four buildings in five here predate 1980 and more than one in five predates 1940, so the below-grade space this township's claims keep landing in is usually not a modern poured basement. It is a cellar: stone or rubble foundation walls in the oldest stock, block above them, a slab that was poured later than the walls it sits inside, and a stair that comes down into the middle of the room rather than against a wall. That changes the work in three specific ways, none of which is obvious from the top of the stairs.
The walls hold water rather than shed it. Rubble and older block are absorbent and full of voids, so they carry moisture long after the air in the room reads dry, and a reading taken at chest height on a stone wall will say almost nothing about what is happening at the footing. The joints and the wall-to-slab seam are where water sits, and they are where it comes back from.
Everything mechanical is in the room, and it is in the room low down. In a house of this age the furnace, the water heater, the electrical panel, the oil tank and the washer are almost always on the cellar floor, because when the house was built there was nowhere else for them. That, not the framing, is usually the largest line in the job, and a piece of equipment that has been submerged is replaced on its own merits rather than dried and put back into service.
And the stair is the whole logistics problem. Contents that have to come out, panels that have to come out, and equipment that has to go back in all move through one narrow opening, often with a turn in it. That is worth saying out loud at the estimate, because it is the difference between a two-day removal and a four-day one, and it is the part that gets discovered rather than planned.
What is common to every job in the state — how contaminated water is classified, how drying is judged finished, what the rules require in a house this old before a tear-out, what you sign and what you get three days to undo — is set out on the statewide page. What is worth deciding here, and only here, is what goes back into a room that the 2011 file says will probably be wet again: which finishes, mounted how high, and where the mechanical equipment lives afterwards. That is a rebuild decision, and it is far easier to make while the wall is open.
- A stone or rubble cellar wall holds water in its joints long after the air reads dry.
- In this housing stock the mechanical equipment is on the floor, which usually makes it the biggest item.
- One narrow stair decides the schedule more often than the square footage does.
Common questions
The Passaic gauge here is rising but the Peckman is what floods my street. Which one should I be watching?
Both, and for different reasons. The Peckman responds to rain falling on this side of town and it responds fast, so it decides whether you have minutes. The Passaic gauge at Little Falls responds to rain that fell across a very large basin upstream, so it usually gives hours — and it is the one with thirteen published impact statements naming the roads that go under at each reading, which makes it the more useful of the two for deciding when to move what is in the basement. If you only learn one number, learn the Passaic reading that puts water on your road, because that is the one you can act on before it arrives.
