The Los Angeles Clippers have received final approval from Inglewood's city government to begin construction on their new arena next summer. The Clippers announced the approval from the city council Tuesday, along with a joint deal to buy the publicly owned property on the arena site for $66.25 million. Clippers owner Steve Ballmer is building a privately financed 18,000-seat arena along with a practice facility and corporate offices for his NBA franchise, which has shared Staples Center downtown with the Los Angeles Lakers and the NHL's Los Angeles Kings since it opened in 1999.
