Charlotte-Douglas International Airport Expansion

Mecklenburg County, NC

Charlotte Douglas International Airport is one of the busiest airports in the world. Since 2015, passengers have increased from 28 million to over 50 million. The airport has crafted a master plan that will sustain the growth and construction it anticipates will happen well into 2035.

EnviroScience—formerly known as ClearWater Environmental Consultants, Inc.—secured multiple 404 and 401 permits for the airport’s 3rd parallel runway and other master plan projects. 

The third runway measures over 9,000 feet long and includes two taxiway bridges constructed on 650 acres. Total impacts of the third runway included 22,559 linear feet of stream, 1.148 acres of wetlands, and 7.522 acres of open waters.

Additional permitting included expanding a new entrance road, parking lots, and parking decks. The total impacts of these projects included 2,395 linear feet of stream and 3.035 acres of wetlands.
