Parris Island, SC, vulnerable to impacts of climate change
Highest spot is 13 feet above sea level
PARRIS ISLAND, S.C. — Rising seas are encroaching on one of America’s most storied military installations, where thousands of recruits are molded into Marines each year amid the salt marshes of South Carolina’s Lowcountry region.
Marine Corps Recruit Depot Parris Island is particularly vulnerable to flooding, coastal erosion and other impacts of climate change, a Defense Department-funded “resiliency review” noted last month. Some scientists project that by 2099, threequarters of the island could be under water during high tides each day.
Military authorities say they’re confident they can keep the second-oldest Marine Corps base intact, for now, through smallscale changes to existing infrastructure projects.
Maj. Marc Blair, Parris Island’s environmental director, describes this strategy as “the art of the small,” a phrase he attributes to the base’s commanding general, Brig. Gen. Julie Nethercot. In practice, it means such things as raising a culvert that needs to be repaired anyway, limiting development in low-lying areas and adding floodproofing measures to firing range upgrades. Others advocate much larger and more expensive solutions, such as building huge seawalls around the base, or moving Marine Corps training away from the coast altogether.
Parris Island has an outsized role in military lore and American pop culture as a proving ground for Marines who have served in every major conflict since World War I. It remains a crucial training ground, along with Marine Corps Recruit Depot, San Diego. But the rising sea is proving to be a formidable enemy.
Salt marsh makes up more than half of the base’s 8,000 acres, and the depot’s highest point, by the fire station, is just 13 feet above sea level. It is linked to the mainland by a single road that’s already susceptible to flooding.
Low-lying areas on the island and the nearby Marine Corps air station already flood about ten times a year, and by 2050, “the currently floodprone areas within both bases could experience tidal flooding more than 300 times annually and be underwater nearly 30 percent of the year given the highest scenario,” according to the Union of Concerned Scientists.
Military reports have for decades acknowledged threats from climate change to national security, as wildfires, hurricanes and floods have prompted evacuations and damaged bases.
