Just catching up and from what I remember......
King's Dock was just a CGI and a discussion about the parcel of land. Don't recall anything else ever being public.
For Kirkby
@davek is right, there was a lot of documentation, you can't have the government and barristers getting involved without it.
For the stadium itself, although a shocking design, it was large. I remember viewing the floor plans which were available and recall large parts of the stadium being left empty for possible future use as a museum, shop etc. There was very little imagination. There were also mock ups from Kirkby town centre etc.
Therev were also other documents, environmental impact, retail impact, transport strategy etc. Ultimately it was never going to be passed as there was just too many obstacles to overcome, notably a desperate transport plan, a detrimental effect to neighbouring Liverpool shopping centres (due to departure from the regional framework) and very direct questions about funding (including who would benefit from a future sale of the club).
I don't think this scheme compares with either of the above.There seems to be a real will from stakeholders to see this through and there's no real opposition.
