I have read that the city does not own the canyons, which would also imply that there is some type of area around the canyons they do not own. I think these questions about what would you do border on irrelevant, as I would say very few, if any, on here know what the land looked like prior to any holes being built. It also depends on budget as well. On a tight budget, it may be as good as could have been done 50 years ago. Now with a near unlimited budget, I am sure Fazio could make anything he wanted with enough dozers and tree spades. So to me, the question is not answerable.
