In March 2019, mayor Bill de Blasio announced a Lower Manhattan Coastal Resiliency Plan, which would create barriers and possibly extend the shoreline at a cost of $10 billion. At the time, four of the project's phases had funding and were set to start construction between 2020 and 2021. The projects include berms as well as retractable dams and barriers in Battery Park City, the Financial District, and Two Bridges. In 2019, the city installed a temporary barrier while the permanent barrier is being erected.
