Cumbria County Council says it can expect a greater cut to its budget following yesterday's Autumn Statement.
Deputy Leader Patricia Bell says the Chancellor's promise to protect police funding only means the axe will fall elsewhere.
The authority already needs to find £37million in savings for 2016/17 - that could rise when the local government funding settlement is announced next month.
Councillor Bell told today's cabinet meeting that "these are uncertain times."
Today at Cumbria County Council's Cabinet meeting, Deputy Leader of the council Patricia Bell made the following statement in respect of the Chancellor George Osbourne's Comprehensive Spending Review statement yesterday: "The Chancellor announced the Comprehensive Spending Review yesterday afternoon. However, we still don’t know what our grant settlement for next year will be from government.
"However, the extent of the protection towards other services, such as the Police is greater than we expected.
"This means that those services that are not protected, like ourselves, will end up shouldering more of the burden of reductions in government spending.
"The Chancellor’s Statement which set out a target budget surplus nationally of £10.1billion by 2019/20 is based on some ambitious economic growth rates of an average 2.4% per year over the next four years.
"Initial indications from our Finance team who were studying the supporting information from government yesterday afternoon, suggest that local government grant reductions will be around 27% nationally over the period.
"This is consistent with our 30% reduction in revenue grants contained in our existing planning assumptions, which we have shared at Council and Cabinet over the last few months.
"As you know, our estimate is that we will need to find a further £80million of savings from our revenue budget over the next three years – this is on top of the £153million we have agreed in budgets over the last five years.
"The draft funding settlement for Local Government isn’t due until the middle of December, it is only then will we know exactly what savings we need to make next year.
"The Chancellor’s statement suggested there may be an increase to the Better Care Fund to reflect increased adult social care pressures and the pressure upon social care providers linked to the national living wage announcement by the Chancellor in June, however, we need to understand what this means for Cumbria.
"Indeed before the Chancellor spoke yesterday the Council had already began consulting on a 2% increase in council tax for next year to help pay for the essential services the people of Cumbria need.
"So, the proposed 2% Council Tax precept for social care, as a county with one of the lowest council tax bases in the country and one of the fastest super-aging populations is not a solution!
"These are uncertain times and the devil will be in the detail. What is unchanged is that we need to save £37million pounds for the year 2016/17.
"The Consultation which Cabinet agreed at its October meeting set out that as £19.5 million pounds of which has already been agreed in previous budget, we will need to make a further £17.5million of savings next year.
"Finally, only once Officers have worked their way through the 300+ pages of the supplementary information produced by the Treasury and Office for Budget Responsibility yesterday, will we know if more savings are required."
Elsewhere, Cumbria Tourism’s Managing Director Ian Stephens made the following comments: “As the tourism and visitor economy delivers yet another year of solid growth for the Cumbrian economy, we are cautiously optimistic that the Government’s Autumn Statement will deliver numerous benefits for tourism in England. The Tourism Alliance’s briefing gives a good overview of the budget and how it impacts on Government spending over the next few years.”
