It will also help keep rates at "sensible levels" while we address the costs of fixing our environment.
"We must continue to support our region to grow to create jobs and security for our people but this growth must be in balance with our environment."

Graham noted the number of young people putting their names forward to become regional councillors in this years election, saying it is "really great to see".
"They will be the future leaders of our region, bringing fresh ideas and new energy to our table and if re-elected I look forward to working with them."
The nominations, which opened on Friday, will close at midday on August 16.
