In March 2007, the AWC unveiled six draft designs for the Kenilworth Avenue pedestrian bridge. Kingman and Heritage Islands — Mayor Williams also proposed transferring Kingman Island and nearby Heritage Island in the Anacostia River to the AWC for development as parks and for the construction of bird and wildlife education centers. Poplar Point — This parcel of land is bordered by the Anacostia River, South Capitol Street, Interstate 295 (also known as the Anacostia Freeway), and the 11th Street Bridges, and is part of Anacostia Park. Although only the federal government held title to Poplar Point, the AWC assumed it would eventually gain control of the area and issued a request for design proposals that would include parks, memorials, and residential housing while maintaining at least part of the area's wetlands. A master planning exercise began in June 2006. A year after President George W. Bush proposed transferring the land to the AWC, the corporation had done little to effect the land transfer, and AWC officials had still not come to agreement on redevelopment plans. In November 2006, the AWC said it was delaying development of Poplar Point until the federal government replaced the Frederick Douglass Memorial Bridge. The AWC released a master plan for Poplar Point in January 2007 that included a 27,000-seat soccer stadium, a hotel, a conference center, 2,000 residential housing units, and a park. Washington Canal Park - AWC planned to create a park-like area along 2nd Street SE between M and I Streets SE, which would provide space for the construction of residential housing, office and retail space, and public parks. The AWC hoped to break ground on Washington Canal park in early 2007. By June 2007, however, the AWC had yet to break ground on any redevelopment project. The AWC's chief executive officer, Andrew Altman, resigned on October 6, 2005. He was replaced by a local developer, Adrian G. Washington, on November 11, 2005. A month after his appointment, Washington approved the creation of an advisory council to help oversee the AWC's redevelopment efforts. Bond sales AWC's initial development efforts were funded by several bond sales. Mayor Williams first proposed a $230 million "payment in lieu of taxes" (or PILOT) bond financing plan in June 2006. The bond sale was expected to generate about $75 million for the AWC, which would use the money to make infrastructure improvements at Hill East, Poplar Point,
