DDC Land Allocation Plans are currently up for public consultation, one relevant document is here -

As I understand the situation (explained to me by a senior DDC Planning Officer when I asked at a public forum) these simply highlight areas that the council have identified as suitable or desirable for development and where there is therefore a presumption that a planning application will be passed provided it meets all relevant planning regulation requirements.
A planning application outside these areas can be just as valid but has to be considered in more depth. No election mandate is required and a lack of one won't prevent an application being passed, that would be a ridiculous situation.
