existing structure between existing support columns, concrete was then re-poured into the area. The original crown of the arena, one of its most distinguishing characteristics, was the countless small ceramic tiles, each measuring no more than a square inch in width. A multitude of the crown's tiles were loosening and many others were discolored. In order to remedy this, a new crown was designed, this time using individual sections of EIFS (Exterior insulation finishing system), which offered the decided advantages of better durability, easier maintenance and improved thermal characteristics. A foundation surface was applied directly over the existing tiles, in order to seal the crown and give the new surface something to adhere to. Once the structural work was finished, the walls, ceilings, doors, floors and other areas involved in the modification had to be put back together. Throughout the entire project, the Los Angeles Memorial Sports Arena remained open for business. The result was a brand-new crown around the exterior of the building, as well as a new terrazzo floor on the concourse level. During an open session meeting on July 17, 2013, the Coliseum Commission authorized the amendment to the existing USC-Coliseum Commission Lease for the operation of the Los Angeles Memorial Coliseum and the Los Angeles Memorial Sports Arena.

This included the rehiring by USC, on a fixed term basis, of the Coliseum/Sports Arena employees who had been working for the commission the previous day. For most of the former Coliseum Commission employees, the fixed term of their employment would be short-lived, ending 10 months later on May 30, 2014. Closure and replacement The Sports Arena was demolished in order to replace it with a more in-demand facility — a soccer-specific stadium that would house an MLS team. On May 18, 2015, Los Angeles Football Club announced its intentions to build a privately funded 22,000-seat soccer-specific stadium at the site for $250 million. The stadium would be completed by 2018. From March 15 to 19, 2016, Bruce Springsteen performed a series of three sold-out concerts, the last events held in the arena. When he introduced his song "Wrecking Ball" during the last concert, he opened by saying
