The re-shaping, aimed at saving a further £25million by 2017, will see 535 officers and staff lose their jobs.
The force have already made cuts of £55million since 2010.
Chief constable Andy Marsh said there had been ‘no choice’ in the decision.
“Saving another £25m means that we have no choice but to make further cuts,” he said.
“With fewer people, we cannot just keep piling the pressure onto a stretched frontline.
“That is why we have fundamentally reviewed what we do, how we do it and what we should not be doing when there is no risk to the public or others are better placed to help.”
The county’s Police and Crime Commissioner, Simon Hayes, added: “The facts now show that we have no choice but to plan for fewer officers and staff, but unlike some other areas of the country, neighbourhood policing will be prioritised with dedicated resource.
“This is tangible evidence that the constabulary now understands that its job is to prevent crime and deliver for victims and that can only be good for public confidence.”
The number of the county’s PCSOs, 333, will stay the same.
There will also be additional focus on rural policing, while vulnerable children and adults will get more protection.
A Resolution Centre is being trialled, whereby experienced police officers are being placed in the force’s call centre to ensure better prioritisation of public calls the right deployment of resources.
It is hoped this will cut police dispatched per year from a quarter of a million to 200,000 every year.
However, emergency calls will be responded to as normal.
Ch Supt Jason Hogg, who will lead on Neighbourhoods and Prevention, said: “Today’s neighbourhood police officers are too often called on to perform other tasks, taking them away from the communities that they serve for prolonged periods.
“This hardly helps us to build trust and so we will end this practice by making sure that they are there when communities need them.
“We have looked carefully at how we can deliver the best service for the public.
“That means thinking beyond just policing and working with partners who share our desire to make communities safer.”
