People in Gedling are overwhelmingly in favour of keeping district and borough councils, according to the leader of the council.
He said non-essential services such as leisure centres and markets would be axed if the new 'super council' went ahead.
Nottinghamshire County Council is looking into a plan to scrap district and borough councils and create a brand new authority which would cover all of Nottinghamshire.
Supporters say the scheme could save as much as £20m a year, which would help protect services.
However the project has faced criticism from district and borough councils, who say it would erode local decision making, and would end up costing more.
Now, the leader of Gedling Borough Council, John Clarke, said: "We do one hell of a lot of stuff that we needn't do, but we do it because we care for the people we represent.
"It really is worrying, and my fear is that if other councils come in and try to take us over, we would lose all that."
Councillor Michael Payne added that the idea was "bonkers".
