on the other side on harney is the b.r.t.so you can't have curb cuts or stopping along the way so that's a restriction there. and then on another side we have a mid block break which is more of a pedestrian experience with people walking along there. so the 20% maximum is to make sure as people are walking in the neighborhood that there interacting with the design that they have a pleasant experience and see something nice when they walk by. that's the experience and we don't want there to be a lot of blank walls and not interactive space around the building at the ground floor so we put limits on it. in this case, however, you still need spaces where pg&e have access and that put us in a position where we had to locate all the utilities on one side. >> would it be appropriate to think of art, for instance, to give it a more cohesive experience like an aesthetic experience? so if we're grog to grant a variance and i understand the reason now, thank you for why we don't want a lot of space staring at people i saw something in
