Only Cllr Desmond Shiels opposed the proposal on how to spend €131 Million next year.
The agreement meant there was no repeat of the scenes earlier this year when a last ditch attempt to block the budget by Fianna Fail and Sinn Fein – in protest at water charges – was stopped by independent councillor John Campbell switching to the Fine Gael/Labour camp.
The council will have €17 million less to spend next year than it had in 2014.
Fianna Fail councillor and party leader in the county Ciaran Brogan welcomed the 31 votes to one in favour of the budget spend.
“There is unity among the parties and the parties are working now together for the good of Donegal and this what people want,” he said.
“We are however short of funding and I hope we can put together a cross-party group to raise it with minister Alan Kelly.”
Fine Gael’s Cllr John Ryan said he agreed with that idea and welcomed the cross-party agreement.
Among the proposals are some incentives and schemes to encourage existing and new businesses.
“We are in a position where the business community could benefit in the next year,” he said.
Sinn Fein’s whip Cllr Mick Quinn said he hoped the council would benefit from capital funds and an overdraft facility.
He said parties working together had committed to do their best for Donegal.
