House Speaker Ron Mariano cast doubt on efforts to funnel more state dollars to the shelter system, which is housing thousands of local and migrant families, including a plan to shuttle surplus revenues to the struggling support network.

The Quincy Democrat did not directly address whether he agreed with Gov. Maura Healey’s plan to cover the state-run emergency shelter system’s $224 million budget gap in fiscal year 2024 with leftover funds from the pandemic era.

But he did express hesitancy with handing the system more money as state revenues continue to face headwinds.

“I mean, obviously, it’s a concern as revenues continue to bottom out and flatten. It becomes harder and harder to support some of these things,” he said after a private meeting with House Democrats.

Healey submitted to the Legislature in mid-December a detailed plan to tap $700 million in surplus dollars to make ends meet this fiscal year and pay down a nearly $1 billion shelter tab in the next, Mariano said he “hasn’t seen anything” and the proposal is “news to me.”

Administration and Finance Secretary Matthew Gorzkowicz and Housing Secretary Ed Augustus laid out in a detailed report submitted to Michlewitz’s committee a blueprint for paying for the shelter system.

While she has not filed legislation on the matter, Healey said she wants to direct $148 million in surplus dollars to shelters and related services, $67 million to support school districts and unhoused K-12 students, and $10 million for immigration and refugee health supports.

Healey also suggested spending $150 million on housing production and preservation initiatives she included in a housing bond bill filed last year.

In a follow-up statement later in the day, a spokesperson for Mariano said even though there are bi-weekly reports from the Healey administration, “there’s currently no legislation before the House, which is what the Speaker was referring to with his comments.”

“The House will wait to see what the administration files before moving forward on this issue,” the spokesperson said in a statement.

House budget writer Rep. Aaron Michlewitz, a North End Democrat whose committee received the report last month, said the Healey administration provided a timeline for how long shelter system funding approved in the fall would last.

“But other than that, I don’t think we really have had too many extensive conversations on exactly what a new bill would look like, what are new spending? How much would it be? What would it look like? We really haven’t had those conversations yet,” he said.

Michlewitz said when the governor files something official, he’ll take a look at it.

“When they file that, we’ll have to certainly take that into consideration and see what it is,” he said.

Mariano also said Wednesday that he agreed with Healey’s move to slash $375 million from the fiscal 2024 state budget as Massachusetts expects to collect $1 billion less in revenues than originally anticipated.

Healey’s decision to cut the budget has drawn criticism from progressive corners of Beacon Hill, including among some state lawmakers who have seen local projects lose funding. But Mariano backed the move, saying “yes, I do,” when asked if he thought cuts were the correct path forward.

“I think that the primary thing that we’re responsible for is submitting a balanced budget,” he said. “We have to keep that balanced no matter what the economic conditions are and we have to respond accordingly.”
