to bring back to you. >> yeah, i like that and i mentioned in the comments about the set-back on hallock, i made it clear it's minimal. the one foot, six inch and the building, i am not talk about that. the shafts and against an alley on the other side that is a service alley. it doesn't make sense. the areas that could be set back on the building are more on california and battery. and more to get the desired aesthetics. and you wouldn't be losing a lot of square footage. but probably more setbacks that tie it into the lower. thank you the my feeling and what i would be supportive of. >> thank you, commissioner hillis. >> i am supportive, i think you crystallized my thoughts. and i talk about setbacks as really a design element. not because we need them there. it's challenging as you drive around the city and pick out a building where there is big additions. they usually don't work, and su -- and you think to yourself who approved that. we want to rise and make this great and it's challenging to add to a building that is not the greatest design. >> commissioner sugaya. >> that said, the

and the tower separation is 1 foot six inches, and on hallock is the union building and that's a flat wall. and while the separation isn't what it needs to be, it isn't anything significant. the wind allowances are two lower and one higher. and while mentioned because of that exception is a new exceedance that wasn't there before. and illuminates by the studies we have. and the green roof and the aesthetics and the sidewalk widening make it a very appropriate building for a very visible and historical street as is california street. and so i like this project a lot. >> commissioner moore. >> i have a couple of questions about this building and i would like to frame the questions it in the larger context of looking at the building per se. we have talked many times about the possible identification of the historic core and trying to find ways to potentially address identification and in the absence of that we have no other tools using those that created the new buildings in context of the older buildings. as a guiding element by which we look at additions such as this. and the one issue
