Living Near the Hackensack River: How to Protect Your Home From Flooding
Homes near the lower Hackensack River face flood risk from the river, the tides, and overwhelmed storm drains. Here is how to reduce that risk before the next big rain.
Where the flood water actually comes from
Homes in the lower Hackensack River valley face flooding from more than one direction, and understanding which one threatens your property is the first step to protecting it. The river itself can come up after a sustained heavy rain, and because the lower river is tidal, a high tide arriving on top of a storm surge pushes water higher than the rain alone would. For homes close to the bank or in the floodplain, that is the most dramatic risk, but it is not the only one.
The second source is the storm-drain network, especially in the denser parts of Hackensack and the boroughs packed in around it. When a hard rain drops more water than the drains can carry, the system surcharges, water backs up into streets and low driveways, and from there it finds basement windows, garage entries, and any grade that slopes toward the house. This kind of flooding hits homes that are nowhere near the riverbank.
The third is groundwater. In an area this close to a tidal river, the water table sits high, and during a long wet stretch it rises further, pushing up through basement slabs and foundation cracks even when no visible water is running anywhere. A persistently damp basement after rain, with no obvious entry point, is often this. Knowing which of the three you face shapes everything you do to defend the home.
Keep water moving away from the foundation
A large share of flood damage in this area comes down to where the water goes once it is on or near your property, and managing that is some of the most effective prevention there is. Gutters and downspouts are the first line; when they clog, rain sheets off the roof and pools against the foundation, where it eventually works its way in. Keeping them clear and making sure downspouts discharge well away from the house keeps a surprising amount of water out of the basement.
Grading matters just as much. The ground should slope away from the foundation so water runs off rather than collecting against the walls, and in older Bergen County neighborhoods where the soil has settled over decades, low spots and reverse slopes are common and worth correcting. Window wells below grade should drain and, where flooding is a real risk, be covered to keep storm water from pouring straight into the basement.
For homes that sit low or near the floodplain, these basics are necessary but not always sufficient. They handle the everyday rain and reduce the chronic dampness, but a major river or tidal flood event calls for the heavier measures below.
Defend the lowest level with pumps and valves
Because basements and ground-level spaces flood first, that is where targeted defenses pay off most. A sump pump is the workhorse, and if your home has one, test it before the wet season and consider a battery backup, since the storm that floods the basement is often the same storm that knocks out the power the pump needs. A sump pump that quits at the worst moment is one of the most common causes of a flooded lower level in this area.
For homes that have experienced sewer backups, a backwater valve is worth serious consideration. When the municipal sewer surcharges during a heavy rain, that valve keeps contaminated water from flowing back up through your floor drains into the home. Given how hazardous and expensive a sewage backup is, and how common surcharging is in the dense parts of Hackensack, this is a meaningful safeguard for the right home.
Beyond the mechanical defenses, controlling humidity in the lowest level helps with the chronic moisture that comes with living near a tidal river. A dehumidifier in a damp basement, good ventilation, and quick attention to any musty smell keep the high water table from turning into a slow mold problem even in dry weather.
Have a plan and a number before the water rises
Even a well-defended home near the river can flood in a big enough event, and the most valuable preparation is knowing what you will do when it happens. Decide in advance what you would move to higher ground and keep the lowest level clear of irreplaceable items and anything that cannot get wet. Know where your shutoffs and panel are so you can cut water and power safely if water starts coming in.
Keep the number of a 24/7 restoration crew somewhere you can find it fast, because the middle of a flood is not the time to start searching. The faster a professional crew gets the water out and the structure drying, the less you lose, and in a flood that involves contaminated water, fast professional cleanup is also a health matter, not just a property one.
SafeHaven Restoration works Hackensack and the riverfront Bergen County towns around the clock, both for active flood emergencies and for drying out a lower level that took on water during the last storm. Save 551-351-9474, take care of the prevention basics, and call the moment the water comes in.
Why flood water has to be more than pumped out
There is a common assumption that once the visible water is pumped out of a flooded basement, the problem is solved. It is not, and understanding why matters especially for homes near the river. River and storm floodwater is not clean. It carries silt, street runoff, and whatever the storm dragged through it, so a basement that took on river water needs more than a pump; it needs the contaminated materials removed and the surfaces disinfected before anything is dried.
The drying that follows is just as important and just as easy to underestimate. In the humid air of the lower river valley, a basement that is pumped out but left to dry on its own stays damp for a long time, and damp plus organic material plus the warmth of an enclosed space is exactly what grows mold. The moisture soaked into drywall, framing, and any porous storage has to be pulled out with commercial dehumidification, not left to the air.
This is why a flood near the river is a job for a crew with extraction, sanitizing, and drying equipment, not a wet vac and a box fan. The pump-out is the visible part; the contaminant removal and the verified drying are what actually return the home to a safe, dry condition. Catching all three is what keeps a flooded basement from becoming a mold remediation a month later.
Living near the Hackensack River means planning for flooding from the river, the storm drains, and the high water table. Keep water moving away from the foundation, defend the lowest level with a tested pump and the right valves, have a plan and a number ready, and treat any flood water as contaminated until it is properly cleaned and dried.
