|a Because sea level could rise 1 m or more during the next century, it is important to understand
what land, communities and assets may be most at risk from increased flooding and eventual
submersion. Employing a recent high-resolution edition of the National Elevation Dataset and
using VDatum, a newly available tidal model covering the contiguous US, together with data
from the 2010 Census, we quantify low-lying coastal land, housing and population relative to
local mean high tide levels, which range from [approximately]0 to 3 m in elevation (North American
Vertical Datum of 1988). Previous work at regional to national scales has sometimes equated
elevation with the amount of sea level rise, leading to underestimated risk anywhere where the
mean high tide elevation exceeds 0 m, and compromising comparisons across regions with
different tidal levels. Using our tidally adjusted approach, we estimate the contiguous US
population living on land within 1 m of high tide to be 3.7 million. In 544 municipalities and
38 counties, we find that over 10% of the population lives below this line; all told, some 2150
towns and cities have some degree of exposure. At the state level, Florida, Louisiana,
California, New York and New Jersey have the largest sub-meter populations. We assess
topographic susceptibility of land, housing and population to sea level rise for all coastal
states, counties and municipalities, from 0 to 6 m above mean high tide, and find important
threat levels for widely distributed communities of every size. We estimate that over
22.9 million Americans live on land within 6 m of local mean high tide. |
