The US science-based analytical organization Climate Central has published a report identifying 287 energy facilities located within 4 feet of the high tide line in the 22 coastal states of the lower 48. This includes 96 electric facilities, 56 oil and gas facilities, and 130 natural gas facilities.
Climate Central has previously identified areas of the US at risk of ocean inundation by about 2030. The four foot level is an alternate way to express that risk. Nearly five million people live within the area at risk of coastal inundation. Extensive areas of industrial properties are also at risk.
