being demolished. The claim was met with silence from the Raiders, who continued to explore San Antonio, and opposition from Alameda County. On February 19, 2015, the Raiders and the San Diego Chargers announced plans for a privately financed $1.7 billion stadium that the two teams would have built in Carson upon being approved to move to the Los Angeles market. Both teams said they would continue to attempt to get stadiums built in their respective cities. The stadium was approved by the Carson City Council but was defeated by the NFL who voted in favor of building Inglewood's SoFi Stadium and relocating the St. Louis Rams back to Los Angeles with the Chargers as the second LA team thus shutting out the Raiders from the Southern California market. In January 2016, Mark Davis met with Las Vegas Sands owner Sheldon Adelson about building a domed stadium on the UNLV campus for the Raiders and the UNLV Rebels. The stadium location for what became known as Allegiant Stadium was later moved to a site across Interstate 15 from Mandalay Bay. After the approval of $750 million from the state of Nevada and backing from Bank of America after Adelson pulled out of the project, the Raiders submitted papers for relocation to Las Vegas in January 2017, and on March 27, the Raiders' relocation to Las Vegas was approved. The team planned to continue to play at the Coliseum through the 2019 NFL season and relocate to Las Vegas in 2020. In December 2018, the city of Oakland sued the Raiders and all the other NFL teams for millions in unpaid debts and financial damages, which prompted Raiders management to declare that the team was leaving after the 2018 season. After the 49ers blocked an attempt by the Raiders to relocate to Oracle Park for the 2019 season, the Raiders and Coliseum Authority reached an agreement in principle on February 25, 2019 to allow the Raiders to return to the Coliseum for 2019 with a provision for 2020 in case completion of Allegiant Stadium was delayed; the Coliseum Authority approved the lease on March 15 while the Alameda County Board of Supervisors and Oakland City Council voted in favor of the lease on March 19 and 21, respectively. On January 22, 2020, the Raiders officially moved to Las Vegas becoming the Las Vegas Raiders. Notable events Raiders and A's move in
