Four-term mayor and D.C. Council member Marion Barry has not yet been laid to rest, but District elections officials have already chosen the date when his former constituents will choose his successor.

A special election to fill the Ward 8 council seat will be held April 28, the D.C. Board of Elections said Monday. The announcement followed a board vote certifying the vacancy.

Barry spent nearly 16 years on the D.C. Council — nearly as long as he spent in the mayor’s office. He served as an at-large member from 1975 to 1979, then was elected to represent Ward 8 from 1993 to 1995, then again from 2005 until his death Nov. 23.

Candidates to fill Barry’s seat can pick up ballot petitions starting Monday, Dec. 8. To qualify for the ballot, candidate must collect the signatures of 500 Ward 8 residents by Jan. 28.

The elections board  is expected Wednesday to set another special election — most likely for the same day — after it certifies the results of last month’s general election. Muriel E. Bowser’s ascension to the mayoralty has opened up the Ward 4 council seat she has held since 2007.

Both races are expected to attract a wide array of candidates.
