This document discusses strategies for making New York City more resilient to future climate impacts like flooding from storms. It summarizes statistics on how many more residents, jobs, buildings and floor area are now located in the 100-year floodplain compared to previous maps. It also discusses projections that the costs and likelihood of major storms like Sandy will increase significantly in the coming decades due to climate change. The document then presents several strategies being explored to make the city more resilient, including coastal protections, upgrading infrastructure, adapting buildings, restoring habitats, and strengthening communities through collaboration and local services.
