serviced amount of defects on the rooted they cause a public safety their have damaged bark and condone with the root pruning in order to get the sidewalk repair prone to failure the hearing office say they pose a danger we would like to safe all the trees those four are a potential hazard due to their current condition and in ku klux klan conclusion the hearing officer stated the situation has been brought to the attention which the city and now the city must make the situation safe now

at the earlier hearing the i believe it was discussed the condition placed on the by the forester replacement of the trees in 48 inch boxes that are more than 3 times the standard replacement which is 15 inch boxes there was extensive discussion about the boxes about two weeks ago my clients are ready to go to the 48 inch position and replace 4 to 4 but put in 5 this is what the forester asked for 5 sturdy trees in the black a.m. cash i want to take a minute to respond to some of the comments from the

speakers. >> we certainly agree with her that this is a historic district it is with important architecture on a steep sleep that requires the 90 degree partnering but unfortunately results in the cars when necessary go into the spaces they tend to bump into the trees this is another situation that will be remedied by the replacement trees they'll be placed further away not to be hit by cars now, it's true that the consultant for the russian hill neighbors was mr. ted he had requested a pool test and the few read the memo of the results of prior hearing it states that

the board and commissioner fung correct me if i am wrong the board continued the hearing so that the russian hill neighborhoods could perform a pool test they never did and i'm surprised they didn't take responsibility they never did the test or approached my clients to do the tests they refused to pay the money so the pool test was not done they should have acknowledged that arrest i'm happy to hear the city a discussing taking badgering back lie down but liability is not at issue not an issue for my clients i don't think it's relevant the third speaker mr. kendrick

you know he stated that removal of the damaged trees would hurt the block i think that's an over statement considering the trees will be replaced but it will take a number of years to get to the height but not a determination by the city not bid any of my clients so in conclusion, we support the finding of the bureau and we didn't hear anything from the neighbors and i did not see anything not brief that was compelling or provided any significant evidence that would 0 testify overturning the finding of the bureaucracy of

forest re. >> one quick question more than one. >> so your clients are condominium to the replacing the trees any issue there. >> no. >> i have a question. >> in the ensurpg 7 or 7 or 89 years to your knowledge has there been independent involving the trees. >> i don't know the year one fell over and was replaced by my client and one tree has already been replaced. >> i don't know if it was one of the four it might have been a tree down the street. >> if you don't know that's fine. >> you're asking. >> is there any incident involving the trees like a limb falling off. >> no. >> purely out the curiosity why

did our clients allow this for 7 or 8 years. >> i was not involved in 2008 i don't know answer to that i just don't know. >> my question the removal of the tree is simply a safest issue. >> simple simply a safety issue. >> i'm looking 9 swaths hadn't been replaced it's a much larger issue than the trees coming down. >> it's a public safety. >> why have not your clients addressed that. >> as mr. kendrick i believe testified he was talking about a sewer but many much of that sidewalk has been replaced seriously multiple times by the

mosser company. >> i'm looking at the briefs if there's significant damage. >> there's ongoing damage i mean four large trees large roots and constantly expanding it's an ongoing maintenance issue. >> okay. thank you. >> okay. we've hear from the department now. >> good evening, commissioners chris buck with the department of public works urban forest fortunately i was around when we elevated the younger buck back then (laughter). >> strike that for the 230rd. >> i'd like to provide a little bit of brief background when i know about the pool tests and couple of other comments and try

to quickly electro through the i understand to provide a very belief i don't intend to take a lot of time i know there's a lot of material presented i talked about carli short who is still with bureau streets and mapping there was some initial effort on good faith efforts gordon man had been performing pool test and will 1ru678 offered up the use of the equipment, however 20 didn't feel comfortable being part of the pool assessment didn't want to over step his boundary i don't believe anyone was found to that comfortable certainly public works was not comfortable running a pool test

we hadn't done hundreds of these so paychecks was not julian in to say we'll jump go in and provide the truck there's a number of the element that is part guesswork we didn't want to bungle this we backed away were we're going to 0 - you passes the buck. >> we passed the buck 8 years ago there was an attempt to make the pool test happen we only maintain 1/3rd the streets in the san francisco 202/3rd's are are the property owners responsibility we approved certainly not a tree we'll accept the responsibility

additional one thing we said if the removal is approved we'll condition the repairs all the repairs to the sidewalks with only way to have the bureau streets mapping and another sidewalk supervisor and the if i am wrong the way that property owners will be cited to defects can be and the i'd like to suggest we may post a cutters or courtesy notice since 8 years the posting were on the trets i understand there's a 3 hundred foot mailing we do a posting letting the immediate neighborhood or folks walking their dogs permits are good for 6 months we allow that to permit to be expanded to 6 months it is not putting it up for protest

only a courtesy test of removal we can include final side that's one suggestion with that lastly i want to state that 48 inch boxes are large it requires large equipment a pretty large flatbed truck to you pull this box tree that is very large 4 by 4 feet that contains a lot of soil it's very heavy we recommend again, the trees be placed away from the curve and but one someplace applies to move a tree and no protests we only ask a 15 gallon tree many of the trees don't get protested across the city we've bumped up from a 24 to a 36 to a 49 box

permanent or replacement tree so public works feels that's a large tree the largest as possible with that, i mean, i'll do a quick witness no. run through i'll go in order of a-6 a and b to follow the agenda this evening thank you for the overhead 6 a from 10 to 59 did trees that is fronting the frontage and there's some slither reduced vigor on the top of the canopy the overall vigor of the tree is go slithering reduced from when we looked at it 8 years there's been some swaths repairs

at the because of the trunk when the screen in the discolored photo on the bottom lightly colored white sidewalk but there remains a number of damaged scares that need to be repaired regarding 6 b the property that has two properties would share the legal responsibility of a single street tree the tree was planted on the property line this is the tree today of the four trees this tree has faired the best over the years it's obedience pruned there's very little canopy so the bigger is still there, however, the tree residence on top of the sewer line 5 inch by 5 inch scare runs

perpendicular that's where the sewer line goes there notice way to plant it it shall say to be plant but it will front 10 61 and room to plant between the waterline and the other vault to the right it's a little bit close to the canopy but that's still a viable replanting site then to conclude the remaining two subject trees are adjacent to 1041 so this is 6 feet species black wood or cashes their green all year round there's decreased in the overlay health of the fondle there's

sidewalk damage those photos were taken a few housing or hours ago tree bases may be expanded not to cut the routines roots but extensive rancher to the sidewalk the two trees adjacent to 1041 broadway have a little bit of a lean towards the street that's natural looking for light over the building, however, the because of both trunks are damaged by the cars parking at 90 degrees i didn't take measurement but certainly 8 years of damage has occurred with those trees in addition to the damage to the because of the trunks of the trees tree one of the two trees at 1041 broadway has an old

pruning cut with a large injury that has preventions of decay their large stems the major stems the one on the left extended out over the road it is a weak point of the tree that's worth noting tree one although it looks to did layperson there's patches of on side i wouldn't see with a healthy black or cash tree tree 2 as an extensive amount of tree balcony damage as has signed of rusdz vigor to conclude the department approved the removal we understand that all neighborhood love trees typically our department approvals trees for

removal when there's a compelling reason poor performance and species and parents of failure we deny oath tree remove black or cash is not a good tree not on our tree replanting lettuce for 90s for reason of large limb and failures with root and to conclude the species didn't allow a lot of the root injuries so the vigor those trees will decline once the repairs have been made it's our desire to see the trees be approved for remove upholding the 48 inch box

removed. >> i have a couple 6 questions would you have expected to have seen for decay and changes in what you found i guess today or yesterday and i'm a little bit surprised that there hadn't been significant limb or stem failures we have not root pruned some black root or cash we used to have a lot of them some days we've seen complete root failures so their urban predictable and one thing that didn't surprise me because the sidewalk repairs have not took place if they've been made 6 or 7 or 8 years ago because the repairs have not been made it

didn't spriets me they're hanging in there bill the item itself is languishing. >> so the repairs to the sidewalk are as old as this case i thought it was - so. >> so the top tree above the balcony that's been repairs repaired there's repairs made to the tree site the tree the second tree does have sidewalk repair along the curbing curve so two of the four trees have sidewalk repairs the second tree could use for sidewalk repair and the third and fourth tree based on what i see there are extensive sidewalk repairs not made. >> so and socially the sidewalk repairs with root damage that is

somewhat repairable. >> we do socially associate a vigor the trees to the amount of new leafs and when the species is root pruned we see a decreased vigor with the damage trungdz that the vigor is directing once you make those repairs and that's why we approved the removed those trees are not going to handle root pruning. >> would wyoming when there's a requirement for replacement in this case what are your enforcement mechanisms so if those don't took place. >> when the permit to approve the tree for removal we allow the prove or disprove 6 months to remove the tree and we'll allow typically six months

extensions dpoon the circumstances the mechanism is that failure to replant trees we'll basically threaten a fine the same if that for removal without at fin is $679 or the value of the tree the urban forest directs the public works to issue the fine and also plays a lien on the property the trees are still required to be replanted. >> in our experience has that happened. >> most trees are replanted and it's largely courageous or occurs because the property there's a lot of pertains that mean well but months slip by and we get a call saying this trees

was removed i want to see the replacement we follow-up and send a letter and remind them of the rodent and give them a shortened window ones suggestion that i've seen in the brief is that perhaps if approved for remove a condition could be of a shorter replanting period which could allay some of the fears. >> i'm sorry i'm not trying to monopolize do you have a speeds recommendation. >> there are several species the desire and it was a resulting condition of the public works removal there are 3 species recommended won the brisbane box within a magnolia and the red flour gum so we

specified 3 species every green house getting to a large status. >> how quickly. >> the trees regrowing themselves. >> i'm getting closer to the height. >> it's going to take a long time we recognize the loss of the canopy is going to be an quack on the street we're talking many, many years it's obviously not going to look the same you don't i can't give you a date depending on the growing conditions it will be a set back so it will take i'd like years with those trees you'll feel like canopy out increase in 10 years you'll feel like oh, look those trees are filling in terms of of getting back to the size with those

species you're looking at 15 years to 20 depending on which species is selected. >> how old are those trees. >> as an arrest warrant bolster i would say those trees are 40-year-old off the top of my head they're not necessarily remarkably old those are short species theirs not outcomes their you know they're a little bit of a challenge. >> is there a range for normal longevity of those species. >> i would say thirty to 50

years thirty years a number of things go parolee if in their not properly pruned 50 years they've been pruned rigging and kept up after. >> you said that when the sidewalks were repaired yovrm there will be cutting of the roots right and the trees will not handle that well is that based on - >> it's based on starring at trees everyday and looking at the trees that have been damaged at the sidewalk and been repaired and you see a year later half the canopy is dead one way to recommend against maland a tree who species are

being removed and this is certainly that species there's some species we never get a removal and the canopy never sloundz never seems to decline it's based on what we know on the species and what we've experienced but in things like conferences and seminars it's published those species don't do well. >> given the brrldz sat those on its rights didn't do anything what's the harm of seeing once the sidewalks are repaired or is it a catch-22 the sidewalks won't be repaired until the trees are removed if it didn't

cause a danger to the public we had bad weather and winds it gives pause. >> we often will there's been several instances where public works will approve a tree for removal we'll make a decision to deny the request to remove the tree, however, the property owner meetings needs to move forward public works will come out and evaluated the trees impacted if we feel the amount of roots being removed we're comfortable we might allow the trees to be 0 there and monitor them one sign of a tree not

doing well at canopy decline much nor dramatic is the total root failure trees give you warning they start declining a little bit of a slight lean and very often you'll get members of the community would say you know what we did the repairs we allot did property owner to make them and those trees are not fairing well and you have a condition if those tries are not fairing well, after repairs that at that time the permit to remove be issued perhaps at the discretion of the public works. >> one exchange with that option here we approve the trees for resolve they're not good

campaigns these candidates being the medicine quarter to assess it when the sidewalk is being removed. >> my question so i assessed you mentioned only one of the trees will have to be moved i see a sewer line and electrical boxes so the replacements you checked equip for the one tree. >> that's correct the one at the top of the hill there's no room between the driveway and the balcony when i was on site i wasn't aware the condition the remaining trees one adjacent to the frontage both will be replaced and this on the frontage removal of 4 trees to

replace 5 i believe there's room to make room for a total of 5 trees i believe that would have been reviewed 8 years additional no utility jumbled out at me today thank you. >> thank you. >> so we'll take public comment can i side a show of hands no public comment on this item okay. we'll move on to rebuttal ms. rogers your team as 9 minutes. >> hello, again so i just wanted to make a couple of comments one of the things that occurred to me lvns to some of the testimony is appears that the
