"U.S. coastal cities face billions of dollars in costs for the extensive infrastructure projects needed to protect against rising seas and worsening storms. From Boston to Miami, government officials are only beginning to grasp the enormous expense of what will be required."
"For cities in the United States, the price of infrastructure projects to combat rising seas and intensifying storms is coming into focus — and so is the sticker shock.
In Boston, where many neighborhoods have been built and recently expanded in low-lying areas, an estimated $2.4 billion will be needed over the next several decades to protect the city from flooding, one study says. That report came as the city abandoned plans to build a harbor barrier that would have cost between $6 billion and $12 billion, which researchers concluded was economically unfeasible.
In Charleston, South Carolina, the mayor said last year that the city, which floods regularly during high tides, had an estimated $2 billion in needed drainage projects.
In Norfolk, Virginia, the Army Corps of Engineers has recommended a $1.4 billion series of seawalls and other infrastructure to protect part of the shoreline. As with many cities, that’s just the start."
