Adjacent Construction

Metro's Office of Joint Development and Adjacent Construction (JDAC) leads the review of construction projects adjacent to WMATA Metrorail and Metrobus property, facilities, and operations.

General inquiries should be sent to the JDAC@wmata.com and should include a short narrative about the proposed project along with a site plan showing the location of the activities in relation to WMATA's properties, facilities, and/or any nearby cross streets.
