“We are keeping a watchful eye on the risks that are coming our way up I-95, and down the New York State Thruway,” Mr. de Blasio said.

A spokesman for the state Division of the Budget, Morris Peters, said that this year’s state budget allocated $16.5 billion in aid to the city, which he said was more than 40 percent of funding awarded to all local governments, and a half-billion dollar increase from the previous year.

If the preliminary plan had been expected to provide hints as to how the mayor would adjust the spending-as-investment approach to municipal governance that characterized his first term, there were few signs of such a shift.

The record number of city workers — currently at 320,000 full- and part-time employees — is still set to rise to 324,000 this year. The city is pressing forward on a plan to secure 300,000 units of affordable housing, and add a public preschool program for 3-year-olds.

Carol Kellermann of the nonpartisan Citizens Budget Commission called it a “wait-and-see” budget.

When the mayor last updated his plan in November, she said in an email, “we looked forward to more information on how the city would respond to possible losses of federal and/or state support in the January preliminary budget. Still waiting and not seeing.”

The absence of new transit funding could open a third front in the battle over who gets blamed for the failures of the subway system, and the cost of fixing it: Corey Johnson, the City Council speaker, has vowed to put more money into the budget for the authority.

Mr. Johnson has appeared interested in trying to move the mayor on the issue, but on Thursday, he drew closer to Mr. de Blasio and said that he would not support more money for the M.T.A. without guarantees from the authority that the money would be well spent.
