Your proposal is acceptable. However, do not remove any trees until you receive City approval.

Subject: Tree protection for lot 12 in Ash Creek
Todd,
I met with Dale Richards to review the tree protection fencing for lot 12 on Ash Creek Estates Friday afternoon.
While a fence was there, it was not installed to be permanent as the amount of blackberries on the lot is excessive, as it
would be on any empty lot in the coastal northwest. The location of the temporary fence is further to the west away from
the protected trees than called for in the tree protection plan. In addition, there are two trees, a 17 inch diameter alder
and a 28 inch diameter Western red cedar that are to be removed to build the new home. The alder is considered to be a
hazardous tree (I will submit photos and a hazard tree report on Tuesday) as it has lost some of its upper leaders and the
Western red cedar will be mitigated for per Dale.
After discussing the situation with Dale and then calling you, it was decided to allow the temporary fence to act as a limit
of encroachment for excavation equipment to reach in and pull out the blackberries where the final location of the tree
protection fence needs to be. I will be inspecting the site to ensure that the excavation equipment does not or has not
encroached into the final tree protection area. The excavation equipment will be allowed to reach into the tree protection
area under my supervision to removed blackberries and other undergrowth as necessary to allow for the completion of the
landscape later. The removal of the blackberries within the tree protection zone will be done by grabbing the berries with
the equipment and pulling them out of the ground. No excessive excavation beyond an inch deep will be allowed to
occur, none if tree surface rooting is encountered.
Once the blackberries and two trees are removed, The tree protection fence will be installed supported by posts every ten
feet that extend into the ground at least two feet and fully support the four foot tall metal fencing. In addition, signage
placed at least every 75 feet will identify the fence as a tree protection fence and provide phone numbers to call if there
are any questions. I will submit a letter indicating the fence has been properly installed after it is done.
Please let me know if you have any questions or concerns regarding the approach that is being suggested in order to
properly remove blackberries and the trees that are to be removed while protecting the trees that are to be retained.
