New York Harbor Storm Surge Plan
- The Army Corps' NY & NJ Harbor & Tributaries Focus Area Feasibility Study (HATS), begun after Hurricane Sandy, tentatively selected Alternative 3B in July 2022 at about $52 billion[2]
- The plan has 12 storm surge gates and coastal barriers across more than 41 miles of shoreline, with 14 years of construction; final designs were anticipated from 2025 and construction from 2030[2]
- Largest gates are on the Arthur Kill and Kill Van Kull and at the entrance to Jamaica Bay; onshore defences include seawalls and floodwalls in East Harlem, Lower Manhattan, southern Brooklyn and the Rockaways[2]
- It could cut coastal-storm damages from 2044 to 2093 by an average of $6.2 billion a year, but the gates do not address sea level rise or rainfall flooding such as Hurricane Ida[2]
- The largest alternative, a $119 billion five-mile barrier from Sandy Hook to Breezy Point, was mocked by Trump, study funding halted in February 2020 and restarted in October 2021[2]
- Riverkeeper called HATS "fatally flawed" and other groups raised habitat and trapped-runoff concerns; Jamaica Bay is expected to see the largest environmental impact[2]
