mr. decosta, please come forward. >> so i'm here. there are many astute people in the audience. i watch them on the tv, and i'm here to talk about our watershed here in san francisco, and i'm here to talk about another topic, which is known to you all, tech no logical term of dewatering. so as much as we talk about our technical term ms. gener-- ter general, and california law, we should be paying more attention to our watershed. our watershed plays an important role. as human beings, we have many different types of human being, but you know, i represent the first type of people of this area, the ohlone, who respect mother earth. and when it comes to water, the way indigenous people look at water, water is life. that is why we went all the way to north dakota to represent the people of san francisco, all san franciscans and the bay area, to state categorically that we respect water. water is important. we know about it, but we don't pay attention to it. i haven't said that -- you all do your research on how we take care of our watershed in san francisco. i worked at the presidio
