The four coastal cities-Miami, New York, San Francisco, and Copenhagen—each is implementing long-term flood prevention measures. Miami is located in the most hurricane-prone region in the U.S. and is showing signs of subsidence, so flood prevention is critical. New York City was hit by the storm surge of Hurricane Sandy in October 2012 and was forced to take long-term flood measures. Similarly, widespread inundation caused by heavy rainfall in July 2011 forced Copenhagen to take action. A recent report by Moody Financial Analytics ranked San Francisco as one of the cities with the highest risk of rising sea levels in the U.S. Each of the four cities has adopted flood prevention measures within the framework of climate change adaptation. These projects are still ongoing and could serve as a model for Hong Kong and other coastal cities in the Greater Bay region.
