The council is already suggesting levels of service may be trimmed to save money and to stave off a big rates increase.
This could affect things such as the frequency of lawn mowing, park and reserve upkeep.
Mr Crosby is reluctant to head down this path, saying it has the potential to create a false economy, but Councillor Steve Morris sees it as an opportunity to employ a new tactic to rein in council spending.

It is a good statement to make but he will also have to accept that cutting services is not a solution in itself.
