text: JBG hired architect César Pelli and the architectural firm of Hickok Warner Cole to draft a 10-year, $200–$300 million master site plan that would renovate all three existing buildings, bring improve street-level retail opportunities, and add one or more residential buildings (similar to the "Banneker Village Center" plan proposed by the city). In May 2004, the National Children's Museum proposed building its new museum in the center of L'Enfant Plaza. But when the pace of redevelopment of L'Enfant Plaza slowed, the Children's Museum decided in November 2004 that it would build elsewhere.
  Banneker Park demolition plans
  Various proposals to redevelop or eliminate Banneker Park in the late 1990s and throughout the 2000s also threatened to radically change the nature of L'Enfant Promenade. By the early 1990s, the park had suffered from lack of maintenance, deterioration of some of its features, and the fountain had stopped running. In 1996, the nonprofit Washington Interdependence Council won permission from the NPS, which managed the park at the time, to raise $3 million in funds to build a life-size statue of Banneker for the park and to make other improvements (such as bas relief sculptures depicting Banneker's achievements on the limestone circle surrounding the overlook). In 1997, the NPS partially restored the park (including restoring signage, getting the fountain running again, and adding a small interpretive exhibit), and D.C. and federal officials sponsored a rededication ceremony there.
