Chinatown. A site with hotels, office space, parks, residential housing, retail shops, and restaurants was envisioned. As part of its development effort, the AWC feuded publicly with the D.C. Sports and Entertainment Commission, calling for underground rather than surface parking. The Washington Nationals' ownership demanded above-ground parking as well. A deal was struck in June 2006 to build both parking garages above-ground, but to surround them with high-rise condominium buildings so they would not be eyesores. When the deal collapsed three months later, the AWC tried to buy the land for $1 million. In December 2005, the AWC named two master planning teams to help oversee the design of the Baseball District. When the cost of building the stadium soared by 25 percent to $667 million, the AWC was asked to sell development rights on its land adjacent to the stadium to cover the cost overruns. By June 2006, feuding over the development had resulted in Mayor Williams' creating an Office of Baseball on his staff to oversee development of the Ballpark District. A draft master plan was released in late June 2006. Southwest waterfront A second major initiative was the Southwest waterfront development — a mile-long section of land bordered by between the 12th Street SW, M Street SW, Maine Avenue SW, and the Anacostia River. The proposed development was the first revitalization effort in the area since the mid-1960s. But the property was controlled by the National Capital Revitalization Corporation (NCRC), another quasi-government corporation established by the D.C. government. In February 2006, the NCRC agreed to give the waterfront property to the AWC in exchange for $25 million, $24.5 million in city-owned land, and the right to develop three other large city-owned parcels of land. The AWC asked for proposals that included "cultural space" (such as a museum, musical performance space, or theatre), a hotel, office space, parking, residential housing, and retail space. Seventeen companies responded with proposals. Five were chosen in June 2006 by the AWC to submit more detailed proposals, and two selected to submit final proposals two months later. PN Hoffman/Struever Bros. Eccles & Rouse was chosen in September 2006 to be the lead developer. But the development proposals were stalled because, two years after AWC and NRCR agreed to the land swap, the transaction had still not been formalized. The D.C. City Council attempted to pass legislation in November 2006 to force the land
