To quote their planning web site

"After consultation with a wide range of interest groups in the North West and the general public, Regional Planning Guidance for the North West (RPG13) was published in May 1996. The Guidance provides a broad framework for land use planning in the Region. Local authorities in the North West, in drawing up their development plans, must have regard to RPG13."

Here you see that they do consult people and to get views across you need to be an input to a 'interest group' such as CPRE.

Regional Planning Guidance for the North West
ISBN 0117532673 £9.50.

If you can find something in it which supports your views on a development and is contrary or supplements information in the UDP you have arguments that planners will listen too.

Of interest to those in Standish they do appear to be keen on urban regeneration and preserving Greenbelt and should have a new document out soon with more 'robust' policies.
