An online budget tool is available for input of views on the budget for 2015/16 and onwards.
So if you are fed up with pavement potholes or think less should be spent on refuse collection or building 'affordable' housing this is the opportunity for your views to be taken into account.
Although of necessity this is a blunt tool to create your preferred budget, it is a means of getting your views over.
I recommend you give it a go and get your views into the system. The budget tool is here with the background details here.
