What is actually going on
A basement floods in one of three ways: water comes through the walls or floor from saturated ground, it backs up through a floor drain or sewer connection, or surface water flows in through a window well, a door or a low entry. River Edge sees all three, and FEMA's NFIP claims records for ZIP 07661 show when it sees them most. Of the 104 lifetime claims, 24 date from 2011, most of them from Hurricane Irene, and 18 from 2007, largely from the April nor'easter that year. Those were long, heavy rains on already-wet ground, the kind of storm that raises the Hackensack and fills Coles Brook at the same time. Below the Oradell Dam the river is tidal, so a storm surge from the south can hold water levels up just when rain from upstream is arriving; on the morning Sandy arrived, borough police closed Hackensack Avenue as river water reached Main Street. When the river and the brook are high, the drainage that would normally carry stormwater away slows down, and basements on the lower streets can take water from below and through the walls even if the river itself never reaches the house. Cleanup in that situation is not just pumping. The water is contaminated, finished materials it soaked generally come out, the slab and walls must be cleaned and dried, and someone should then look at why the water got in, because the same storm pattern will come round again.
What to do right now
Keep out until the power is safe
If water is near the panel, a furnace, a water heater or any outlet, do not go down the stairs. Shut off power from upstairs if you can, or call the utility.
Do not pump out too fast after a river flood
If the ground outside is still saturated, emptying the basement quickly can let soil pressure push on the walls. When the water came from flooding, lower it gradually or let a contractor judge the pace.
Photograph the water level
Before anything is moved, take photographs of the depth on the stairs or walls, the entry point if you can see it, and the contents sitting in the water.
Lift what you can safely reach
Move boxes, documents and electronics upstairs if you can reach them without wading through deep water. Leave heavy furniture for the cleanup team.

Warning signs worth acting on
- Water appearing at the joint between the floor slab and the wall during a long rain, typical when the ground around a River Edge basement is saturated and the brook and river are high.
- A floor drain that bubbles or pushes water up as the Hackensack rises, which suggests the drainage it connects to is backing up.
- White, chalky deposits on the lower courses of a block wall, left behind by water that has seeped through before.
- Rust on the feet of a water heater or furnace in a basement that seemed to stay dry, a sign of past standing water.
- Window wells holding water after rain, which can overflow into the basement in the next storm.
Who you should call, and why
For a River Edge basement flooded by storm or river water, the first call is a restoration contractor equipped for contaminated water. Once it is dry, bring in a foundation or waterproofing contractor to look at how water entered, and a plumber if the drain backed up — a backwater valve on the sewer line is a plumbing job. Because the risk here clusters in a few named storms, prevention work between them is worth more than repeated cleanups.
Water-damage restoration contractor
Extracts water, removes contaminated finishes and contents, cleans and dries the slab and walls, and logs readings to a dry standard.
Foundation or waterproofing contractor
Assesses seepage through walls and floor, and options such as interior drainage, a sump system or exterior grading.
Licensed plumber
Checks the sewer lateral and floor drain, and fits a backwater valve if drain backup was part of the problem.
What a professional normally does
Extracts and assesses
Standing water is pumped and vacuumed out, then each material is checked. Carpet, pad and drywall reached by flood water are normally removed under the IICRC standard.
Cleans the structure
Concrete, block and framing are cleaned of silt and contamination before drying, so that residue is not sealed into the building.
Dries slab and walls
Dehumidifiers and air movers run until the concrete and remaining framing read dry. Masonry holds a lot of water, so this stage takes longer than many owners expect.
Hands over a record
Photographs, moisture logs and a list of removed items form the basis for any claim and for decisions about how to rebuild.
Before you let anyone start work
Most disputes with a restoration company start with something that was not agreed in writing on the first day. These take a few minutes, even in an emergency.
- Get a written scope and estimate before work starts, with the drying and any rebuild as separate documents.
- Look up the company’s New Jersey contractor registration yourself, and ask for proof of liability insurance.
- Ask who will be in your home, and whether any of the work is subcontracted.
- Read any authorisation or assignment-of-benefits form before you sign it.
- Photograph your belongings before anything is moved, and ask for an inventory of anything taken away.

What drives the cost
We do not publish prices. For a River Edge basement, the source and depth of the water and how much of the space was finished drive most of the cost.
- Depth of water and how far up the walls it reached.
- Whether the basement was finished, and what with.
- The volume of stored contents that need removal or cleaning.
- How long the water stood, especially if access was delayed by the storm.
- Whether the drain or sewer line needs work as part of the fix.
- Any waterproofing or drainage improvements added afterwards.
Insurance documentation checklist
Whether a flooded basement is covered is decided by your insurer under your policy, and basements are one of the most restricted areas in both homeowners and flood policies. In River Edge, where claims cluster around storms like Irene, it helps to show clearly what kind of event caused the water.
- Photographs of the water depth, its entry point and the contents in it.
- The date and the storm involved, and whether the river or brook was high.
- A list of damaged contents, with photographs and approximate age.
- Any flood policy declarations page, as well as your homeowners policy.
- The restoration contractor's scope, moisture logs and disposal list.
- Receipts for pumps, dehumidifiers or anything else you paid for to limit the damage.
Local context
FEMA's NFIP records for ZIP 07661 show River Edge flood claims concentrated in a few storms — 24 in 2011, mostly Hurricane Irene, and 18 in 2007, largely the April nor'easter. The Bergen County Hazard Mitigation Plan puts about 10.7 per cent of the borough's land in the FEMA 1 per cent annual chance zone, mainly towards the Hackensack and Coles Brook.

Common questions
Why did my basement flood when the river did not reach my street?
When the Hackensack and Coles Brook are high, stormwater drains slowly and the ground around foundations stays saturated. Water can then come up through the floor or in at the wall joint, or back up through a floor drain, without the river ever reaching the street.
Is there a way to know a bad storm is coming for River Edge?
Watch for long, heavy rain forecast on already-wet ground, especially combined with a surge warning for the tidal Hackensack. Those were the conditions in the storms that produced most of the borough's NFIP claims. Moving belongings off the floor before such a storm is the cheapest protection available.
Should I put the drywall back the same way?
If your basement has flooded more than once, consider materials below the likely water line that tolerate wetting, and keep valuables and utilities higher. A waterproofing contractor can advise on reducing entry before you refinish.
Do I need a plumber as well as a cleanup company?
If water came up through a drain, yes. A plumber can inspect the sewer lateral and fit a backwater valve so that drain backup is less likely next time.
