About 35 percent of Belmar's 1.6 square miles is water. The borough is wedged between the Atlantic on the east and the Shark River on the north, where a large municipal marina fills part of the bay and the inlet opens to the ocean beside Avon-by-the-Sea. The average elevation is about 13 feet, and the 2020 census counted roughly 5,900 residents.

Ocean on One Side, Shark River Bay on the Other
The Shark River is really a tidal bay of about 800 acres. Very little fresh water flows into it compared with the salt water that moves through the inlet with every tide. For Belmar, that means the north side of town faces the same tides and storm surge as the beachfront, just arriving from a different direction. A nor'easter or tropical storm can pile water into the inlet and up into the bay while rain is falling on the streets, and low blocks near the marina and riverfront have nowhere to drain.
Sandy showed the oceanfront exposure plainly in October 2012, when the Belmar boardwalk was destroyed. Damage across New Jersey from that storm was heaviest in Ocean and Monmouth counties, and the Sandy Hook gauge to the north recorded a surge of more than 8.5 feet.
Summer Rentals and Houses Left Empty
Beach towns with plenty of seasonal homes and summer rentals see a recognizable pattern of water damage, and owners of those properties in Belmar should watch for it:
- Leaks that run for days or weeks in a vacant rental before anyone notices.
- Pipes in unheated or partly heated houses that freeze during winter cold snaps.
- Heavy use in summer that wears out washer hoses, toilet supply lines and water heaters.
- Roof and window leaks after storms that go unreported because the owner lives elsewhere.
Owners who live out of the area can reduce losses with a simple routine: shut off the main between tenants, install inexpensive leak sensors near the water heater and washer, and arrange for someone local to check the house after any big storm.
Cleaning Up After Bay and Storm Water
Water that comes in from the Shark River, the ocean or overflowing streets is contaminated, and it is handled differently from a clean pipe leak. Providers usually extract standing water, remove soaked carpet, pad, insulation and drywall above the water line, then clean and disinfect the framing before drying begins. Appliances, HVAC equipment and water heaters that sat in salt water often need replacement. Ask for moisture readings and photos at each step; insurers use them to settle both storm damage cleanup and flood claims.
Keeping Mold Out of Closed-Up Beach Houses
Humid shore summers and houses closed for long stretches are a reliable recipe for mold. Wet materials can start growing mold within a day or two, and a shuttered house traps the moisture. After any leak, open the house up, run dehumidification, and remove what cannot be dried. Where water sat for days before discovery, mold remediation with containment protects the rest of the house while the damaged materials come out.
Flood Zones and Coverage Before the Next Storm
The borough's website links a flood zone lookup tool for Belmar addresses, and FEMA's Flood Map Service Center provides the official map. Knowing your zone matters, because only a separate flood policy covers water rising from the river or ocean. Burst pipes and appliance failures fall under homeowners coverage, while sewer backup usually needs an added endorsement. Landlords should also confirm what their policy says about vacancy, since some limit coverage when a property sits empty for long periods. Neighbors across the inlet face similar issues; see the Neptune page for the Shark River Hills side of the estuary.

Frequently Asked Questions
Why does the north side of Belmar flood even when the beach is fine?
The Shark River is a tidal bay connected to the ocean by the inlet. Strong onshore winds or a storm surge can push water up into the bay and onto low streets near the marina and riverfront, sometimes while heavy rain is also falling. The beachfront and the riverfront can flood for different reasons at different times.
My rental flooded while it was empty. What should I do first?
Shut off the water main if a pipe is the source and the power to wet areas if you can do so safely. Take photos before moving anything. Contact your insurer and a restoration provider quickly, since water that sat for days increases the chance of mold. Check whether your policy has vacancy limits and tell your adjuster when the property was last occupied.
How do I find my flood zone in Belmar?
The borough's homepage links a flood zone lookup tool, and FEMA's Flood Map Service Center has the official flood maps. If your property is in a mapped zone, a flood policy may be required by your lender. Even outside the zone, the borough's low elevation and water on two sides make flood coverage worth considering.
