Redevelopment is any new construction on a site that has pre-existing uses.

Variations on redevelopment include:

Redevelopment projects can be small or large ranging from a single building to entire new neighborhoods or "new town in town" projects.

Redevelopment also refers to state and federal statutes which give cities and counties the authority to establish redevelopment agencies and give the agencies the authority to attack problems of urban decay. The fundamental tools of a redevelopment agency include the authority to acquire real property, the power of eminent domain, to develop and sell property without bidding and the authority and obligation to relocate persons who have interests in the property acquired by the agency. The financing of such operations might come from borrowing from federal or state governments and selling bonds and from Tax Increment Financing.

Other terms sometimes used to describe redevelopment include urban renewal (urban revitalization). While efforts described as urban revitalization often involve redevelopment, they do not always involve redevelopment as they do not always involve the demolition of any existing structures but may instead describe the rehabilitation of existing buildings or other neighborhood improvement initiatives.

Court won a record 24 of those titles during her career. She also won 19 women's doubles and 19 mixed doubles titles, giving her a record 62 Major titles overall. She is the only woman to win the mixed doubles Grand Slam, and she did it twice. Her all surfaces (hard, clay, grass and carpet) career match winning percentage of 91.74 (1177/106) is an all-time record.Her win-loss performance in all Grand Slam singles tournaments was 90.12% (210–23), at the French Open 90.38% (47–5), at Wimbledon 85.10% (51–9), at the US Open 89.47% (51–6), and at the Australian Open 95.31% (61–3). She also shares the Open Era record for most Grand Slam singles titles as a mother with Kim Clijsters. The International Tennis Hall of Fame states, "For sheer strength of performance and accomplishment there has never been a tennis player to match (her)". She is regarded by some to be the greatest female tennis player of all time.
