WASHINGTON — The Kennedy Center is backing away from plans to build a floating stage on the Potomac River as part of its $100 million expansion project.

The center presented an updated design Thursday. Instead of the floating pavilion, architects are planning for a land-based pavilion overlooking the river to house performances, workshops, events and a cafe.

Kennedy Center President Deborah Rutter says her staff has been discussing and debating the design since the project was announced in 2013. She says the new design is more practical for performances and events. Rutter says a land-based pavilion also will be more sustainable for the future.

The changes have delayed the project about 16 months. The center had planned to open its expansion in May 2017. The new target for completion is September 2018.
