The JDP represents a very full programme of work with some significant investments. Given its complexity and timeframes, reaching out to 2022/23 and beyond, the JDP will be reviewed regularly and may change as our planning assumptions become more certain.

The Authority has reviewed its work programme to ensure that the focus continues to be on priority 1 and priority 2 projects. Projects with priority 3 and above are on hold or pending.
