In November 2016, Director Adcock was elected to her seventh term on the Little Rock City Board of Directors. She is the longest-serving City Director of either gender in that form of government in Little Rock history. (Only two aldermen have served longer on a City of Little Rock legislative body.)
She was first elected to the City Board in 1992. She has subsequently been elected in 1996, 2000, 2004, 2008 and 2012. From January 1995 until December 1996, she served as Vice Mayor of Little Rock.
Director Adcock has been active in establishing neighborhood associations throughout the City. She is also active in Neighborhoods USA (NUSA) and has worked for Little Rock to host the national conference twice. She has worked to establish the Landbank Authority and to create the Little Rock Animal Village. Her latest creation is Working Together in the Community, which is focused on helping integrate the Hispanic population into Little Rock.
