City Comptroller Scott Stringer on Friday fired off a four-page letter to the U.S. Army Corps of Engineers condemning their plan to construct offshore storm surge barriers in New York Harbor.
In the letter, Stringer castigated the corps’ proposal for not adequately protecting coastal communities from the threat of sea level rise and associated flooding. The Comptroller’s letter also highlighted the long construction timeline associated with the storm barriers and their high cost estimate — noting that the largest of the options outlined in the proposal would take a quarter of a century to build out, cost six times that of shorefront resiliency options, and endanger the delicate ecosystem of the harbor including the region’s network of marshes and wetlands that are critical to mitigating storm surge.
Stringer said he is calling on the agency to implement an integrated and environmentally-conscious approach that’s focused on onshore resiliency measures including localized floodwalls, dune and wetland restoration, living shorelines, reefs, and levees. Stringer’s missive noted that this approach was the only way to protect the city from rising sea levels, storm surge from non-catastrophic weather events, and increasingly catastrophic storms in the future.
The letter follows a May 2019 report published by the comptroller, “The Costs of Climate Change: New York City’s Economic Exposure to Rising Seas,” which exposed substantial underspending of federally-appropriated Superstorm Sandy recovery funding that the City had not yet allocated to protect vulnerable coastline communities including only 57 percent of a combined $14.5 billion in federal funds. The report concluded that lagging spending posed a threat to the 520 miles of coastline citywide, which is estimated at a combined property value of $101.5 billion within the city’s current 100-year floodplain map — marking a more than 50 percent increase in value since 2010.
“There’s no question about it — a future Superstorm Sandy will come and New York Harbor will bear the brunt of it. Too many of our waterfront communities are all too vulnerable to the next storm, or even the next high tide,” Stringer said Friday. “I am urging the Army Corps of Engineers to get shovels in the ground on shorefront resiliency options like floodwalls, dune systems, wetlands, and levees that can protect New Yorkers and their livelihoods. Lives are at stake, homes and businesses are on the line, and futures hang in the balance. We need to act with urgency, plan strategically, and build out resiliency efficiently in the era of climate change, because time is not on our side.”
