INDIO, Calif. -

Nearly 100 people gathered for the groundbreaking of a new County Law Building in Indio.

Construction will begin this month on the three-story, 90,000-square-foot facility, which will house law offices for the district attorney and the public defender's office at the corner of Highway 111 and Jackson Street. It will also be home to a county law library. District Attorney Paul Zellerbach said it's long overdue.

"The old county administration building is 45 to 50 years old," said Zellerbach. "It served us well over the years, but it had a lot problems."

The law building will be a public-private partnership where neighbors can go, get help and enjoy the new library and restaurants.

The old County Administration Center will be demolished to make room for nearly 1,300 new jail beds and create 350 new jobs at the East County Detention Center.

"It's a $400-million investment in eastern Coachella Valley, with a $40-million ongoing payroll once we get those jail beds up and hire necessary staff," said Riverside County Supervisor John Benoit. "It's a huge investment."

City leaders said this is the greatest year of expansion for Indio.

Zellerbach and his 250 employees expect to settle in to the new law building in April 2015.

"I think the citizens, the city of Indio, will be very proud of this facility or even go to it. It's going to benefit everybody," said Zellerbach.
