Because this project includes more than a Speedway track, it includes various things such as a cycling velodrome, a community centre, BMX track, 12 5-a-side pitches and some more. Speedway is basically a turn-off for the council, every other times it's been proposed it's fell on it's arse, placing it in a project with the rest of this should provided a big enough attraction to approve.
The guy also spearheading the bid is bit of a big bollox in British Speedway and he's worked wonders at his current track King's Lynn - does a lot of community stuff which gets him in council's good books. He's the kind of bloke who can convince the councillors to proceed with planning permission - sadly they aren't many of these guys who have a big enough interest in Speedway - most promoters are charlatans who don't pay riders, don't improve the stadium and let bills go unpaid.
