I read through part of the proposal ... it is 611 pages. It sounds like the problem isn't saturation on the trails but uphill capacity. Wouldn't they be better served by upgrading the lift infrastructure around the current trails?
I know one thing I hate about some resorts are layouts that try to spread out traffic rather than have a strong centralized system. It forces you to the sides of the resort and if you ever want to get to the central lodge or cross over, you have to deal with traffic in the middle.
