National Capital Planning Commission (NCPC): Federal Transportation Elements and Parking Policies

The General Services Administration (GSA) and National Capital Planning Commission (NCPC) have developed parking policies that establish goal parking ratios for Federal facilities in the National Capital Region (NCR). These ratios are geographically based, aligning with a facility’s proximity to the NCR urban core and transit services. 

These parking ratios were refined as part of an in-depth NCR Federal Parking Study conducted by NCPC in September 2017. The study was incorporated into the Transportation Element of NCPC’s 2020 Federal Element Comprehensive Plan for the National Capital. 

The Transportation Element outlined various goals for the Federal government, with the established parking ratios serving as a direct metric for evaluation within Federal facilities’ transportation management plans (TMPs). 

Parking Ratios for Federal Facilities: 

  • L’Enfant City – Washington, DC historic core – One parking space for every six employees (1:6) 
  • Transit-Rich Corridors – Highly Metro-accessible portions of the Historic DC Boundary – One parking space for every four employees (1:4)

  • Transit Accessible – Historic DC boundary (including Arlington County and portions of Alexandria, Virginia) as well as suburban locations within 2,000 feet of a Metrorail station – One parking space for every three employees (1:3) 
  • Suburban Areas Beyond Metrorail – All other locations in the NCR – One parking space for every two employees (1:2) 

Parking ratios mainly apply to employee parking, with visitor parking, fleet parking, and other mission needs to be considered separately.

Federal Workplace Element policies aim to discourage the establishment of new employee-intensive facilities in areas with limited accessibility. Instead, the focus is on directing new Federal development to reduce transportation demand, permitting facilities to exceed parking ratio standards when feasible.
