The money is being used to expand local correctional facilities to guarantee space for a growing inmate population.
The county has just under 4,000 inmate beds. According to sheriff's officials, the $100 million infusion will go toward adding another 1,200 beds, with the Indio Jail being the favored location.
The jail expansion will cost about $237 million, requiring $130 million of county money.
