Attached is the report I originally sent with a paragraph added at the end which speaks to the emergency. Happy too, to meet with with you on site and walk you through my evaluation. We currently have this removal schedule for July 5. Thanks for letting me know if we should postpone that.

Below is our code definition that the Emergency Removal uses. Immediate Danger of Collapse, Tree. A tree that may already be leaning, with the surrounding soil heaving, andlor there. is a significant likelihood that the tree will topple or otherwise fail and cause damage before a tree removal permit could be obtained through the non-emergency process. immediate danger of collapse does-not include hazardous conditions that can be alleviated by pruning or treatment. The comhination of that and the remainder of your submittal is sufficient I think to grant the Emergency Tree Removal. } Let me know if you have questions, i i Thanks, 3 3 3 I Nathan Emerson i Assistant planner 541.552.2£152 Tel From: Chris John Imaiito:cj.chrisi hn@gmaii.com Sent: Friday, June 22, 2018 3:23 PM To: Nathan Emerson <nathan.emerson@ashland.or.us> Subject: Re: 1090 Benson Way I don't use the term emergency lightly, It usually eludes to the fact that there is a "eminent" risk of failure or that the tree is in the process o€ falling over. This one is borderline. It is clearly a high risk tree and it will most likely fail in the relatively near future. A strong wind even could topple it, or it could go next week. This one walks the line of "high risk" and "emergency." While perhaps not an immediate emergency, there is enough of a chance that it will fail i before the 40 day period that I would be remiss if I didn't recommend its immediate removal. 1 On Fri, Jun 22, 2018 at 2:21 PM, Nathan Emerson <naihan.emerson@ashland.or.us> wrote: ( Hi Chris, Should I move the Benson Wy tree removal permit forward via the normal Tree Removal Permit route? 1 know there was a question as to its qualification as an emergency tree removal.

The tree is a native black oak, quercus kelloggii. It measures 32.5" DBII and approximately 65' tall. The tree is of moderate health, exhibiting signs if crown dieback. This dieback is sometimes an indicator of root damage and/or root rot. Mr Wolske and the building's tenants were concerned about the lean of the tree towards the building, amount of deadwood in the crown, and evidence of decay at the base of the tree. I was initially not overly concerned with these issues. It is a large old tree exhibiting signs of a slow decline. The crown dieback I felt was worth farther investigation as it could be a sign of ar milartia root rot, common with this species and occasionally a cause of tree failure, A more thorough risk assessment however, revealed extensive decay at the base of the tree. Soil probing and sounding with a mallet revealed a cavity of rot encompassing roughly 35% of the circumference of the tree's base oil its tension side. This coupled with the lean of the trunk and the presence of a major target led me to qualify this as a high risk tree and I reconrrnend removal. A completed ISA risk assessment form has been attached. Given the extensive decay and the lean of the tree towards an occupied building, I furthermore make the rare recommendation that this tree be removed ASAP and be qualified as an emergency removal pursuant to City code. I believe there to be enough risk of failure before the normal permit request process can be completed that I would be remiss if I did not recommend this. There are no treatments or pi-twing options that would alleviate the danger of tree failure. Please contact us if there are any further questions we can help to answer in this matter. I am willing to meet at the site of the tree with City staff if it would be helpful.
