New York City is thinking about building a billion-dollar sea wall and other structures to protect the city from coastal storms and rising sea levels.
This plan, known as Plan 3B, was proposed by the US Army Corps of Engineers in September 2022. It includes:
•A sea wall around Manhattan
•Sea barriers and gates at the mouths of major bays and inlets
•Surge gates
•Flood walls
•Levees
The sea wall would be 12–20 feet tall and run along some of the city's most beautiful waterfront areas. The plan also features a network of clay-colored walls and gates designed to blend in with the city's parks and waterfront plazas.
The idea behind the plan is to protect the city from storms that might only happen once every 100 years. However, some people think that even with this plan, there’s no way to guarantee complete protection.
