Highways development

The council provides advice on measures to mitigate the impact that any proposed development will have on the road network. This includes advising planning authorities when a development will affect the highway.

If you have a concern about a planning application you should make this known directly to your planning authority. For developers seeking pre-application advice and details about charges go to Developing new communities.

Please see our frequently asked questions document detailing the process of how a private estate road can become adopted as highway maintainable at public expense.
