leadership of CEO Renee Lewis Glover (1994–2013), the Atlanta Housing Authority demolished nearly all of its public housing, a total of 17,000 units and about 10% of all housing units in the city. After reserving 2,000 units mostly for elderly, the AHA allowed redevelopment of the sites for mixed-use and mixed-income, higher density developments, with 40% of the units to be reserved for affordable housing. Two-fifths of previous public housing residents attained new housing in such units; the remainder received vouchers to be used at other units, including in suburbs. At the same time, in an effort to change the culture of those receiving subsidized housing, the AHA imposed a requirement for such residents to work (or be enrolled in a genuine, limited-time training program). It is virtually the only housing authority to have created this requirement. To prevent problems, the AHA also gave authority to management of the mixed-income or voucher units to evict tenants who did not comply with the work requirement or who caused behavior problems. In 2005, the city approved the $2.8 billion BeltLine project. It was intended to convert a disused 22-mile freight railroad loop that surrounds the central city into an art-filled multi-use trail and light rail transit line, which would increase the city's park space by 40%. The project stimulated retail and residential development along the loop, but has been criticized for its adverse effects on some Black communities. In 2013, the project received a federal grant of $18 million to develop the southwest corridor. In September 2019 the James M. Cox Foundation gave $6 Million to the PATH Foundation which will connect the Silver Comet Trail to The Atlanta BeltLine which is expected to be completed by 2022. Upon completion, the total combined interconnected trail distance around Atlanta for The Atlanta BeltLine and Silver Comet Trail will be the longest paved trail surface in the U.S. totaling about . Atlanta's cultural offerings expanded during the 2000s: the High Museum of Art doubled in size; the Alliance Theatre won a Tony Award; and art galleries were established on the once-industrial Westside. The city of Atlanta was the subject of a massive cyberattack which began in March 2018. In December 2019, Atlanta hosted the Miss Universe 2019 pageant competition.
