Paramus is better known for Garden State Plaza and the Route 4 and Route 17 shopping corridors than for its rivers, but the Saddle River runs down the borough's western side and the Ho-Ho-Kus Brook joins it at the Dunkerhook section of Saddle River County Park. Bergen County's hazard mitigation plan counts roughly 782 acres of Paramus, a little under 12 percent of the borough, inside the 1 percent annual chance floodplain. That leaves most homes on higher ground, yet plenty of basements still take water from rain, groundwater and plumbing failures.

The Saddle River and Ho-Ho-Kus Brook on the West Side
The Saddle River travels about 16 miles through Bergen County before emptying into the Passaic at Garfield and Wallington, and Paramus sits midway along it. The USGS gauge on the river at Ridgewood, just upstream, gives a good sense of what the borough faces. Its highest recorded flow, 7,390 cubic feet per second, came on September 2, 2021, after the remnants of Ida. The next highest was 6,770 cfs during Irene in late August 2011, followed by the September 1999 peak during Floyd. A smaller but notable rise came as recently as January 2024.
Homes closest to the parkland along the river and the brook confluence are the ones that see overland water. Further from the channel, the more common story is a basement taking water through foundation cracks, window wells or a floor drain while the ground is saturated. The county plan also lists portions of Paramus among areas affected by flooding from the Hackensack River on the borough's eastern side.
Postwar Houses with Finished Lower Levels
Paramus changed fast after World War II. Between 1948 and 1958 the population nearly quadrupled, from about 6,000 to 23,000, as farms gave way to malls and subdivisions. Many of the houses from that wave have since been expanded, and lower levels that were once bare concrete now hold carpet, drywall, home offices and spare bedrooms.
Finished space changes the math when water arrives. An inch of water on a bare slab is a mop job; the same inch under wall-to-wall carpet and pad wicks into drywall and bottom plates within hours. Original copper or galvanized lines, aging water heaters and washing machine hoses are frequent sources in houses of this age, separate from any storm.

Handling a Wet Basement or Commercial Space
Shut off the water or power to the affected area if it is safe to do so, and take photos before moving anything. Then:
- Pull rugs, boxes and furniture out of standing water and onto a dry floor.
- Lift soaked carpet pad off the slab if you can; it rarely survives.
- Note where the water came in: a drain, a wall seam, a window well or a fixture.
- Call your insurer early, and ask whether the loss falls under homeowners coverage, a sewer backup endorsement or a separate flood policy.
A provider doing water extraction will remove standing water first, then cut out materials that cannot be saved and run dehumidifiers and air movers until moisture readings hit dry targets. Retail and office buildings along the highways add complications such as ceiling-mounted sprinklers, roof drains over large footprints and tenant improvements owned by different parties, so expect the landlord, the tenant and their insurers all to be involved.
Mold Risk in Paramus Lower Levels
Northern New Jersey summers are warm and humid, and a basement that was wet even briefly can start growing mold on drywall paper, wood paneling and cardboard within a few days. Running a dehumidifier after the visible water is gone is not the same as drying the wall cavities behind it. If a musty smell lingers or stains appear along the base of the walls, a moisture check and, where needed, mold remediation should come before any new finishes go up.

Flood Maps, Policies and County Preparedness
Because only part of Paramus lies in the mapped floodplain, many owners assume they do not need flood coverage. Standard homeowners policies exclude surface flooding, though, and the 2021 and 2011 events produced damage well beyond the mapped zones across Bergen County. After Ida, Bergen County was among the New Jersey counties approved for FEMA individual assistance. Check your address on the FEMA Flood Map Service Center, and sign up for alerts through the county's Office of Emergency Management, which leads preparedness and recovery work for all 70 Bergen municipalities. More statewide background is on our New Jersey service area page.

Frequently Asked Questions
Is my Paramus home in a flood zone?
Possibly, but most of the borough is not. Bergen County's hazard mitigation plan places about 11.6 percent of Paramus in the 1 percent annual chance floodplain, mostly near the Saddle River and Ho-Ho-Kus Brook on the west side and portions near the Hackensack River. Look up your exact address on the FEMA Flood Map Service Center, and remember basements outside the mapped zone still flood from groundwater and heavy rain.
How high has the Saddle River risen near Paramus?
The USGS gauge at Ridgewood, just upstream of the borough, recorded its highest flow on September 2, 2021, after Ida's remnants. Irene in August 2011 produced the second highest flow, and Floyd in September 1999 the third. Those three storms are useful benchmarks if you are judging how exposed a property near the river or the county park might be.
Who handles water damage in a store or office along Route 4 or Route 17?
It depends on the lease. Building owners usually handle the roof, structure and shared systems, while tenants often own interior build-outs and inventory. Report the leak to the landlord or property manager right away, document the damage, and notify your own insurer. A restoration provider can work for either party, but the scope should be agreed before demolition starts.
