Make bike / skateboard zone in ped. plaza
Open the side walk for non dismount zone, allow the bricks for pedestrians only.
After looking in to this more we have found that this will never be a possibility. Sorry!
The reason the pedestrian plaza exists is because 1.) like you said, its only thirtyish feet wide whereas Kafadar is much, much wider, 2.) because it is less than a year old and we're trying to preserve its quality, 3.) because this area of campus has an extremely high amount of traffic, and 4.) because this area has more skateboard/bicycle/etc. vs. pedestrian accidents than any other part of campus.
I really think the dismount thing is dumb, considering it is not in effect anywhere else on campus. Apparently its too dangerous for bikes to be on a 30 foot wide plaza, but its OK to ride on a 5 foot wide sidewalk through Kafadar
