I wouldn't like to see any of the path be OB. I understand that this is a multi-use park, but it seems to me that if it was a DG park first that had a walking path added then there is no reason to change the game on account of the addition.
I'll gladly wait a few seconds to make sure the fairway is clear before driving, but I really don't see taking a stroke when my drive landed in the middle of the fairway, but happened to be in an arbitrarily paved strip. Chili is a beautifully laid out course...let's not change it more than we have to. I guess there are a few spots (behind 17) that would be appropriate OB for a pro level tourney like RFDO.
If the situation was reversed like at Basil, Parma, or Ellison I would understand needing to take extra precaution to keep out of the way of the paths. In this case however, it's like laying a highway across a railroad track and putting the barricades across the track.
Just my two cents.
