Designations generally provide for longer-term and more flexible protection than a resource consent or plan change. A designation cannot be altered by anyone else, unlike provisions of a plan (anyone is able to apply for a private plan change). The outline plan process also allows for greater flexibility into the future than a granted resource consent does by allowing some of the details of the project or works to be left to this stage.
Designations are also a way of providing for projects or works that might be difficult to comprehensively provide for in a district plan or through the resource consent process. Many large scale activities, network utilities or public works may be contrary to the objectives and policies of the plan, or may not comply with the tests of s104D relating to resource consents for non-complying activities.
In addition, decisions on designations and outline plans are made by the requiring authority (except in the case of a notice of requirement lodged with the EPA or one which is directly referred to the Environment Court for a decision), rather than the territorial authority (as is the case for plan changes and resource consents). This has the advantage of providing long-term certainty for requiring authorities.
Designations can be used to:
Designations override all provisions of the district plan in order to provide for works, projects and network operations.
This recognises the fact that they:
The plan change process can also be used to authorise the project or work. However, the Schedule 1 plan change process is lengthier, with greater uncertainty as to the final result. There would always be a risk of subsequent plan changes as anyone can apply for a plan change, therefore providing a less reliable outcome for the requiring authority.
