(TNND) — California Gov. Gavin Newsom released a model ordinance for cities and counties to crack down on homeless encampments while announcing $3.3 billion in grants for facilities that can treat mental health and substance use disorders.

Newsom said the state has cleared more than 16,000 homeless encampments over the last few years, and now he’s calling on cities and counties to mirror the state's efforts.

Local officials would provide notice and offer help to homeless people before sweeping the encampments under the model ordinance.

“The state has changed, and so too now must the cities and counties,” Newsom said Monday during a press conference. “It is time to take back the streets. It's time to take back the sidewalks. It's time to take these encampments and provide alternatives. And the state is giving you more resources than ever. And it's time, I think, to just end the excuses.”

California voters narrowly approved Proposition 1 last year to provide billions in funding for mental health and supportive housing services.

Part of that effort is to increase housing for homeless Californians.

There’s no disputing the connection between drug use and homelessness for Tom Wolf, a drug recovery advocate and San Francisco native.

Wolf has lived the life of a homeless addict and emerged from the other side to push for change.

He’s now the director of West Coast initiatives for the Foundation for Drug Policy Solutions.

California has over 187,000 homeless people, about a quarter of the nation’s homeless population.

Two-thirds of California’s homeless people are unsheltered.

And public encampments are a big problem in California cities.

A recent study from California researchers also found that over a third of homeless people were regular drug users.

“They take these old motels, they buy them, and then they say this is permanent supportive housing,” Wolf said of how the money is spent. “And they stick people inside a hotel room with their fentanyl.”

Drug recovery services are voluntary, and the supportive housing is unsupervised, he said.

Wolf said he supported Prop 1.

But he’s not happy with how all the money will be spent.

“The organizations that are going to get the funding employ a very permissive form of harm reduction within their treatment programs,” he said.

The organizations that offer housing for addicts don’t ban drugs on their premises, and that leads to overdose deaths. It can also hamper fellow residents who are really trying to get clean and sober, he said.

Wolf wants drug treatment services to be required for people who access housing.

And he’s advocating for a state bill that would permit funds for drug-free recovery housing.

“So, it's not that the money is bad,” Wolf said. “It's who's going to be in charge of spending that money and what organizations get the money. That's a concern."

Newsom’s model ordinance for clearing encampments was impacted by a Supreme Court decision last year that allowed cities to enforce bans on homeless people sleeping in public spaces.

Wolf said that the court decision gave Newsom more latitude to go after homeless encampments.

But Wolf said the state’s claim to have swept 16,000 encampments is misleading.

“I know of one encampment just in San Francisco alone that got swept three times last week, and it comes back every single time,” Wolf said. “But they count each one of those as a successful sweep. The people just go around the corner, and then they come back. Because we're not holding ... them accountable.”

Housing people alone isn’t the answer, Wolf said.

“There are 100 different reasons people become homeless, but our solutions are monolithic,” he said.

And he was skeptical that Newsom’s model ordinance would make a big difference.

“I fully support more treatment options, more beds, more housing,” Wolf said. “However, again, it comes back to policy.”
