MEMPHIS, Tenn. -- Two airplanes once owned by Elvis Presley, the Lisa Marie and the Hound Dog II, could be moved from Graceland to a location down the street under a plan approved Thursday by a county board.

The Shelby County Land Use Control Board approved a proposal from the planes' current owners, OKC Partnership, to place the aircraft on a lot just steps from the Graceland property.

The planes have been situated at Graceland since the mid-1980s, and they are a popular tourist draw. They had been sold after Presley's death and were eventually purchased by OKC Partnership in Memphis.

OKC Partnership and Graceland agreed to bring the planes to the singer's home. Their agreement called for OKC Partnership to receive a cut of ticket sales in return for keeping the planes there.

In an April 7, 2014, letter to OKC Partnership, Elvis Presley Enterprises said the company was exercising its option to end the agreement and asked OKC "to make arrangements for the removal of the airplanes and the restoration of the site on or shortly after April 26, 2015."

The Memphis City Council must approve the plan. If they are moved to the new location, the planes would be part of an outdoor display and museum for tourists to visit.
