The City of Oklahoma City uses Special Zoning Districts as a tool to maintain the character of many neighborhood communities.
Downtown Oklahoma City itself is currently undergoing a renaissance. Between the mid-1980s and 1990s, downtown was unchanged and largely vacant. It was the scene of the bombing of the Alfred P. Murrah Federal Building on 5th Street between Robinson and Harvey Avenues, caused by convicted domestic terrorist Timothy McVeigh; most buildings within a 1-mile (1.6 km) radius were structurally damaged by the explosion, including the old Journal Record Building (now home to the National Memorial museum). Many other buildings, such as the unique international style YMCA building, supposedly one of few remaining in the United States were damaged or destroyed.
White flight during the 1950s and 1960s left much of the inner city abandoned. During the Urban Renewal days of the early 1980s, controversial urban planning allowed for the destruction of almost 50 historic buildings and skyscrapers. Examples include the Biltmore Hotel, which was imploded to make way for the I. M. Pei-designed Myriad Botanical Gardens, the only major Urban Renewal project completed as planned. Many of the buildings which were not destroyed in the Central Business District were covered by new façades or left to Class-C office space. The removal of historic structures left downtown without much retail presence.
In stark contrast to the promise of Urban Renewal, Downtown had not seen a new skyscraper or any sort of major construction project for many years. The last major skyscraper built downtown was the First Oklahoma Tower in 1982 and the Leadership Square complex built in 1984. Leadership Square was originally intended to be a single 60+ floor skyscraper but was later scaled down to two connected towers due to economic downturn.
