The Flooding Character of Salem County

Coastal flooding, driven by strong southerly winds and high tides, is a significant flood character for Salem County. Recent events on January 10, 2024, and April 11, 2024, illustrate this, with water inundating areas along the Delaware River and Bay, and within back bays due to southerly flow preventing drainage. Flash flooding from heavy rainfall also occurs, with 30 events recorded in the last 30 years.

The National Flood Insurance Program (NFIP) data shows a substantial number of claims in Zone A, averaging over $13,000 in payouts and 1.7 feet of water depth. While other zones like X_SHADED and X_UNSHADED have fewer claims, they still experience flooding with average payouts exceeding $3,900 and $4,600 respectively. Residents in coastal areas, along tidal rivers and bays, and those in areas designated as Zone A should pay the most attention to flood risk.

Salem County Flood History

Flash Flood — Jul 9, 2025

A slow-moving cold front produced heavy rain and flash flooding across portions of the region.

Coastal Flood — Apr 11, 2024

High astronomical tides in addition to strong southerly flow resulted in higher water levels, mainly along the Delaware Bay and tidal Delaware River. However, some flooding was observed in the back bays as southerly flow prevented water from draining.

Coastal Flood — Jan 10, 2024

A strong system affected the region with steady southerly flow pushing water up into coastal communities both along the ocean and within the Delaware River/Bay and Chesapeake Bay. Water levels on the tidal Delaware River were higher due to 2 to 4+ inches of rainfall.

Coastal Flood — Mar 9, 2024

A coastal storm moved through, bringing strong onshore flow, which resulted in water piling up along the coast and within back bays and tributaries. Moderate coastal flooding was observed.

Flash Flood — Jul 9, 2023

Widespread showers and thunderstorms brought heavy rain to northern and central New Jersey on the afternoon and evening of July 9. Rainfall totals were as high as 3 to around 5 inches.
