Lincolnshire County Council has asked people to have their say on which services should be protected in the face of further cuts.
The authority says it needs to save a further £90m per year by 2019 due to reductions in Government funding and rising demand for services.
This, along with the £150m of savings made so far, means the council’s budget excluding education will have almost been halved.
The council says it needs to review its priorities.
Council leader Martin Hill (Con) said: “We’ve already started to reduce our operating costs wherever possible, but we can’t find this £90m per year through efficiency savings alone.
“We need to decide which services we believe are essential and which, while desirable, could be reduced, delivered in a different way, or even stopped.
“Public security is a particular priority for us, so we’re proposing to protect funding in areas like safeguarding children and vulnerable adults, gritting roads and highways maintenance.
“That means the savings would need to be found within the other services we provide.
“But we want to know what residents think, and the best way to find that out is to ask them.”
