Dorchester County northwest of Charleston has been one of the fastest growing counties in South Carolina as Charleston's suburbs expand. The county faces serious hurricane risk and hosts Joint Base Charleston — a combined Air Force and Navy installation critical to air mobility and submarine operations for the southeastern US. The Edisto and Ashley Rivers create flooding risk. Hurricane Dorian in 2019 impacted the county and the ongoing growth expands the population exposed to hurricane risk.
