Gov. Andrew Cuomo has proposed on Thursday a three-pronged approach to the remaining roadblocks that have prevented the completion of the state budget, according to an administration source.

The solutions backed by the governor address the issues surrounding charter schools, raising the age of criminal responsibility in New York to 18 and the revival of the 421a tax abatement.

The source called the proposal “a reasonable and fair and non-political compromise.” It was categorized as a deal that would solve the differences over the budget between the two majority conferences in the Republican-controlled Senate and Democratic-led Assembly.

“If the Legislature doesn’t accept it, they will have to explain to the people of the state why they didn’t,” the source said. “Both houses are now considering it.”

Cuomo laid out the plan in a meeting with the legislative leaders in a meeting on Thursday in an effort to end the impasse.

For the issue surrounding post-release supervision in the raise the age discussion, the proposal is to have a panel of officials determine whether a discharged individual should be overseen by corrections officers or the Office of Children and Family Services.

“That should be made by the appropriate law enforcement and social worker counselors who are familiar with the facts and circumstances of that case,” the source said.

On 421a, the issue has been over whether the abatement should be allowed to expire along side rent regulations for New York City.

“The idea of linking it to the expiration of the rent program is a legislative tactic that flies in the face of the desperate need for affordable housing and that affordable housing program took two years to design and should be allowed to operate on the merits,” the source said.

Meanwhile, on the thorny issue of charter school funding — a tuition aid un-freeze that would see aid increase by $1,500 per student paid out by a school district — a potentially large hit for any locality, including $200 million for New York City — the proposal would be to have flat funding for charters this year.

The funding for charter schools would increase going forward through the same percentage increase as local public schools are receiving. The move is expected to generate about $100 million in savings to the state and would be added to foundation aid for the next school year.

Offsetting lost revenue, the state would help facilitate the ability to contract pre-Kindergarten programs and provide more funding through facility aid — basically a form of rent.

Assembly Democrats are meeting now in private conference; Senate Republicans have left the Capitol, but have said they would return if an agreement is in place.
