D.C. Code § 9-401.02
On and after July 1, 1941, when any Capital Transit Company street railway operation shall have been ordered abandoned by the Public Service Commission of the District of Columbia and the Council of the District of Columbia shall have ordered the removal of abandoned tracks, the Capital Transit Company shall pay the entire cost of removing such abandoned tracks and regrading the track area, and, if the street or bridge in which the said tracks have been ordered abandoned is not being paved, the Capital Transit Company shall pay the entire cost of paving the abandoned track areas, which cost, however, shall not exceed the cost of repaving such abandoned track areas with the type, character, and thickness of the paving of the adjacent roadway left in place, and, if the roadway of the street or bridge is being paved at the time of removal of said abandoned tracks, the Capital Transit Company shall pay one-half of the actual cost of paving the abandoned track areas, irrespective of whether the paving is of the type, character, and thickness as that existing at the time of said removal. The Council of the District of Columbia is authorized to settle in conformity with the principles herein set forth, any claims it now has, or in the future may have, for the paving of abandoned track areas, upon such terms and conditions as to time of payment or payments as the Council may determine.
