Call it supply and demand, if you will: The biggest immigration detention center in California is set to get a massive overhaul, which will add 650 beds and a women's wing to the sprawling facility, which already houses thousands.

Nestled in the high-desert area of Adelanto, about 40 miles outside of San Bernardino, the 1,300 bed facility is situated amongst Adelanto's other more notable buildings: San Bernardino county jail and a state prison. It's a massive reminder of the immigration issues this nation faces, and now, with its current overhaul, it will only become more looming.

The facility is already the largest in California, and it currently houses only men in its 1,300 beds. The addition, spurred along by U.S. Customs and Immigration Enforcement (ICE), will add room 650 more, and the detention center will open its doors to women too, once the renovations are complete.

ICE attributes the need for expansion to a growing number of immigration-related arrests in Los Angeles. The ICE officers try to house immigrants near the place of their arrest, and most of the court cases will take months to be heard, so the beds are necessary.

But as positive as ICE is about the need, immigration reform activists aren't so sure. They are set to protest the renovations, citing the for-profit group running the facility, Florida-based GEO Group, as negligent in other cases.

The mayor of Adelanto, on the other hand, welcomes the expansion. His city is at a whopping 18 percent unemployment rate with a $2.6 million budget deficit, so economic improvements are necessary.

And ultimately, Adelanto stands to earn a lot. The city earns 75 cents per day from GEO for every detention bed filled, and according to city officials, the expansion could boost the city’s struggling economy.

“It takes an existing facility, expands it, and creates more jobs,” City Manager Jim Hart said. “That’s a financial benefit for the city.”

Still, as positive as the outlook may be for Adelanto, activists aren't sold. They worry about the detainees, who receive poor quality food and inadequate health care. And despite the long wait, there's never enough time to work on their cases.

“Resources should go to help the children seeking asylum, not to grow private prisons,” said Luis Nolasco of the Justice for Immigrants coalition.
