OAKLAND — Days after a new survey revealed a troubling spike in the Bay Area’s homeless population, Gov. Gavin Newsom on Tuesday unveiled more details behind the task force he’s set up to tackle the crisis.

Newsom’s Homeless & Supportive Housing Advisory Task Force, which marks the governor’s latest commitment to address the chronic housing instability plaguing the state, will begin traveling the state this summer to see what homelessness solutions are working in different cities and counties. The task force will then issue a report to the governor detailing how California can scale up the most effective solutions.

“It begins with a plan,” Newsom said Tuesday during a media briefing at Oakland’s Henry Robinson Center, flanked by homeless residents who are sleeping at the shelter while they search for housing. “The state has no plan. The state’s been nowhere to be found as it relates to the issue of homelessness.”

The new initiative, which Newsom first announced earlier this year, will be chaired by Sacramento Mayor Darrell Steinberg and Los Angeles County Supervisor Mark Ridley-Thomas. Signaling a special focus on mental health, Newsom on Tuesday also named psychiatrist and neuroscientist Dr. Tom Insel, former director of the National Institute of Mental Health, as an adviser to the task force.

There are 8,022 homeless residents living in Alameda County — up 43 percent from 2017, according to new data from the county’s biennial point-in-time count, released last week. There are 9,706 in Santa Clara County — up 31 percent from 2017. The 2019 San Francisco count tallied 8,011 people – up 17 percent from two years ago.

Newsom previously promised to spend $1 billion to fight homelessness in California, and on Tuesday said that money will fund the solutions his task force comes up with. His revised budget, proposed earlier this month, includes $650 million directed to local governments for homelessness emergency aid, $150 million to address the shortage of mental health professionals, $40 million for rapid rehousing for students and $20 million in legal assistance for eviction prevention.

Oakland Mayor Libby Schaaf applauded Newsom’s efforts Tuesday.

“Oakland stands ready to be on the forefront of this absolute commitment to end homelessness,” she said.

Tekel Carlisle, who has been homeless off-and-on for about two years, gave Newsom a hug during Tuesday’s briefing. Carlisle, 42, is living at the Henry Robinson Center while she tries to find permanent housing.

“I’m just so happy,” she said, “that Gov. Gavin here has just come down and shown his support.”
