Dulles Metrorail - The Environment

The Environment

The Virginia Department of Rail and public Transportation and the project partners conducted extensive research to understand the environmental factors and impact of the proposed Dulles Corridor Metrorail Project . The following factors were assessed to identify the potential environmental consequences:

  • Why transportation improvements are needed in the corridor;
  • Why a Metrorail extension was selected to meet those needs;
  • Other alternatives that were considered;
  • The anticipated economic, environmental and social impacts of the extension;
  • The estimated costs of the extension; and
  • Remaining actions required to implement the Metrorail extension.

The Federal Transit Administration (FTA) approved the first Environmental Impact Statement (EIS) in March 2005. Since then, the Dulles Corridor Metrorail Project has advanced to a more detailed level of engineering, which requires additional environmental review to ensure the Project is in continued compliance with the National Environmental Policy Act (NEPA).

The Federal Transit Administration in November 2006 issued its Record of Decision (ROD) on an Environmental Assessment (EA) prepared by the Virginia Department of Rail and Public Transportation regarding design refinements to the Dulles Metrorail Project.  This ROD approved the final alignment for the aerial portion of the rail line through Tysons Corner.
