The waterfront was gradually transformed with award-winning parks and plazas surrounded by office buildings, hotels and leisure attractions, which reversed the city's decline and became a model for urban renaissance in cities around the world. The renewal of Baltimore's Inner Harbor area began with the adoption of the Charles Center project by the City Council and Mayor Thomas D'Alesandro in March 1958. Between 1958 and 1965, Baltimore renewed the center of its business district by rebuilding Charles Center with office buildings, hotels, and retail shops. At the beginning of mayor Theodore R. McKeldin's second term in 1963, the redevelopment program was expanded to include surrounding the Inner Harbor. Corporate headquarters and hotels were built around the shoreline of the Inner Harbor. A public park and promenade were added for leisure activity and community gatherings. On July 4, 1976, following the rendezvous of Tall Ships in New York for the U.S. Bicentennial, eight ships from other nations visited Baltimore, where they attracted a huge number of tourists. This interest helped spur the development of other tourist attractions – including the National Aquarium, Maryland Science Center, and the Harborplace festival marketplace (operated by The Rouse Company), which opened on July 4, 1980. The nearby Baltimore Convention Center and Hyatt Regency Baltimore Hotel added to the services and resulted in population density and visitors. With the success of the Inner Harbor in the 1970s and 1980s, Baltimore became a worldwide tourist destination and model of urban planning and development. It influenced more than 100 other cities and won more than 40 national or international awards, including a citation by the American Institute of Architects in 1984 as "one of the supreme achievements of large-scale urban design and development in U.S. history". In recent years, the area along the waterfront to the east of the Inner Harbor (in the direction of Fells Point and Little Italy) has been developed with condominiums, retail space, restaurants, and hotels – an ongoing project known as Harbor East. While little development land remains around the Inner Harbor, the available land has been subject to many plans, which have not been realized. Recently completed projects include mixed-use developments incorporating office space, street-level retail, and condominiums, as well as hotel projects such as the Ritz Carlton Residences, a condominium project on Key Highway at the southeast corner of the Inner Harbor. In September 2003, the Inner Harbor area was flooded
