I am not legally equiped to confirm if the draft local plan is legally compliant or not, however due to the significant impact of the plan, and the way to which WBC has previously miss-managed plan submissions, its very likely not to be.

Regarding "Sound", we need to build houses, this no one kind argue with, however where the plan is extremely inadequate is in the transport section. Warrington has become a condensed built up town, the roads, cycle paths and public transport are simple "not fit for purpose", therefore to add thousands of additional cars to them will not work
You have to look at proposing intelligently thought out proposals, the draft plan is vague and ambiguous.
South Warrington has public transport, are they used by anyone under the age of 60, no, why, because the Residents of south Warrington all have cars, they will be the first to have electric cars, but this does not negate the fact that you are introducing the cars to already full roads.

Cycle paths in South Warrington don't exist, to get around you have to use roads, roads you are planning on putting more cars on!!
