and i've learned this from ann arborist i spoke to and also a fellow named lars costello, a uc-davis consultant to san francisco county on street trees and probably is known to ms. short. i quoted, you know, basically our communication in our email that he really feels -- he wished me good luck. i invited him here tonight in terms of participating in this appeal. i'm so sorry that the bureau of urban forestry isn't on my side and isn't helping me in terms of giving me information about those trees and this tree which, you know, in fact shouldn't have been planted. i wish that they could help advise citizens of san francisco about the safest, best trees to plant and warn us of those trees that are likely to disrupt our systems, even if they've been in there for some number of years, because maybe there is something i could have done years ago to, you know, walled off these roots from growing into the sewer pipe. it is far enough away in terms of feet down below the street, i guess, to meet the city's requirements, but for a 35-foot tree, the roots are growing at least 35 feet away fro
