NVTC manages and controls the functions, affairs and property of the Northern Virginia Transportation District, and is made up of six member jurisdictions – the counties of Arlington, Fairfax and Loudoun, and the cities of Alexandria, Fairfax and Falls Church. NVTC's board of directors is made up of representatives from the six jurisdictions, members of the Virginia General Assembly, and a representative of the Virginia Secretary of Transportation.
NVTC also appoints Virginia's members to the WMATA Board. In the 2011 Virginia General Assembly session, legislation was approved to require the appointment of the Virginia Secretary of Transportation's designee as a principle voting member of the WMATA Board to ensure adequate oversight of the Commonwealth's investment in the critical Northern Virginia transit system. The Commonwealth provides more than half of Virginia's portion of funding for WMATA.
