On June 23, 1995, Davis signed a letter of intent to move the Raiders back to Oakland. The move was approved by the Alameda County Board of Supervisors the next month. As the NFL had never recognized the Raiders' initial move to Los Angeles, they could not disapprove of the move or request a relocation fee, which had to be paid by the Los Angeles Rams for their move to St. Louis. In order to convince Davis to return, Oakland spent $220 million on stadium renovations. These included a new seating section – commonly known as "Mount Davis" – with 10,000 seats. It also built the team a training facility and paid all its moving costs. The Raiders paid $525,000 a year in rent – a fraction of what the nearby San Francisco 49ers paid to play at the now-extinct Candlestick Park – and did not pay maintenance or game-day operating costs.
