Lower Manhattan Coastal Resiliency (LMCR) refers to a range of climate change adaptation strategies of coastal management to address impacts on the city in the wake of the extensive Hurricane Sandy flooding of 2012.

Climate change in New York City could affect buildings/structures, wetlands, water supply, health, and energy demand, due to the high population and extensive infrastructure in the region. A seaport like New York is especially at risk if the sea level rises, with many bridges and tunnels in the city. Major facilities for Aviation in the New York metropolitan area, and the New York Passenger Ship Terminal, are also located in areas vulnerable to flooding. Flooding would be expensive to reverse. Tide gauge records indicate a rise in sea level of about 50 cm since 1860.
