EA provided support for an Environmental Assessment at Ronald Reagan Washington National Airport for a New North Concourse. The project components include relocation of utilities within the New North Concourse area; demolition of buildings; modifications the Central Utility Plant, South Hangar Line, airport security fence and gates, and aircraft parking locations; and tenant relocations.
EA prepared the floodplains, wildlife, plants, and special-status species sections of the “Affected Environment” section and analyzed the consequences of the project on these resources. EA also reviewed Federal Emergency Management Agency data for Federal Insurance Rate Map to determine the existence, extent, and governing jurisdictions of any floodplains within the airport. To determine the presence of wildlife and plants in the vicinity of the airport, several nearby areas were researched including the Potomac River, Four Mile Run, and Roaches Run Waterfowl Sanctuary that provide a variety of open water, tidal wetland, and riparian forest habitats for fish, wildlife, and plants.
To determine the presence of known populations, or potential presence, of federally or state-listed threatened and endangered species or supporting habitats within the vicinity of the Airport, consultations were conducted with the U.S. Fish and Wildlife Service, National Oceanic and Atmospheric Administration Fisheries, Virginia Department of Game and Inland Fisheries, Virginia Department of Conservation and Recreation. Searches of online databases maintained by Virginia agencies regarding threatened and endangered species and habitat were conducted, including the Virginia Department of Conservation and Recreation natural heritage resources information database and the Virginia Fish and Wildlife Information Service geographic search database.
