A rock wall that overlooks the marshlands at 29th Street and Central Avenue serves as a barrier against floodwater.
Road projects such as Central Avenue’s reconstruction are a key part of the city’s strategy to protect low-lying neighborhoods from flooding.
During another road project in 2022, the city built rock walls along Central Avenue from 29th Street to 38th Street to prevent floodwater from seeping in from the marshlands.
The waist-high rock walls, also known as berms, act as the first line of defense against flooding that comes from both the bay and the marshlands surrounding Sea Isle’s residential neighborhoods.
Although they are decidedly low tech, rock walls are combined with other measures such as stormwater pumping stations to help ease flooding in Sea Isle and other beach communities at the Jersey Shore.
Sea Isle built its first stormwater pumping station in 2019 at the bay end of 38th Street at Sounds Avenue to protect surrounding homes. Rock walls were built along both sides of 38th Street as an extra precaution against floodwater surging out of the marshlands and bay.
