 As with other DART stations, particularly within the inner sections of Dallas, the City of Dallas has encouraged transit-oriented development in station-proximate parcels to boost economic development.MLK Jr. is one of the City's five prime targets for encouraging mixed-use development near DART; the station area plan released in February 2013 aims to focus growth in an "urban mixed-use area" encompassing vacant lots directly south of the station as well as designating Grand Avenue, Martin Luther King Junior Boulevard and Robert B Cullum Boulevard as corridors to upgrade to complete streets or secondary streetscape areas.Upon its opening on September 14, 2009, MLK Jr. station served as the southern terminus for the Green Line until its second phase to Buckner, where it currently ends, opened on December 6, 2010.
