Tree Maintenance CRA2021-0117CITY OF EDMONDS 121 5th Avenue North, Edmonds WA 98020 Phone: 425.771.0220 • Fax: 425.771.0221 • Web: www.edmondswa.gov DEVELOPMENT SERVICES DEPARTMENT • PLANNING DIVISION `ne. 18y1i June 25, 2021 Traci Brown tracib2wins@gmail.com Subject: Tree Maintenance in Critical Area 626 Elm Place Dear Ms. Brown, You have contacted the city regarding the trimming and removal of eight alder trees located in the common area of the Elm Place development. The trees are located adjacent to Willow Creek. Willow Creek is considered a critical area according to Chapters 23.40 and 23.90 of the Edmonds Community Development Code. Generally, trees within a critical area or critical area buffer may only be removed if they are hazard trees. For City of Edmonds purposes, we consider trees to be hazard trees when the ISA Tree Risk Assessment identifies a tree with an overall risk of High or Extreme. The initial request proposed the removal of some trees and the trimming of other trees. However, the trees identified for removal only had a Moderate tree risk rating and thus are not considered hazard trees. The proposal has subsequently been changed so that trees will only be trimmed for health and safety reason in accordance with ANSI 300 (with the exception of using spurs). The trimming of the trees is considered normal maintenance of vegetation and is exempt from critical area report requirements pursuant to ECDC 23.40.230.C.2. The maintenance of the eight alder trees is approved with the following conditions: 1. This approval only pertains only to the eight alder trees identified in the attached reports. 2. Vehicles and equipment shall be located on private property. Should it be necessary to utilize any portion of the City right-of-way, including the street or sidewalk, to perform any of this work then the contractor shall apply for and obtain a right-of-way construction permit in advance of starting work. A traffic control plan will be required as part of the right-of-way permit application. 3. Contractor/owner is responsible for keeping all debris on site and preventing any silt laden runoff from leaving the site and/or entering the city storm system. 4. Contractor/owner shall repair/replace any damaged sections of curb/gutter, sidewalk or other public improvements in City right-of-way per City standards that is caused by or occurs during the permitted project. Feel free to contact me if you have any questions at kernen.lien@edmondswa.gov, or 425-771-0220.

To Whom It May Concern, This letter is in addition to the Elm Place HOA Tree Report dated December 30, 2020 and addresses the City of Edmond's response to mitigation techniques to reduce tree hazards. It is difficult to reach the tree canopies of some trees without heavy equipment. Using spikes to access the canopy of diseased trees is the most feasible action. Industry Tree Care Standards state the use of spikes for tree removals only and not to be used on trees for preservation. Alder trees (Alnus rubra) 101 and 102 are not suited for preservation and cannot recover from their Phytophthora disease. The damage spikes will incur on Alders 101 and 102 is insignificant to the fungal infection that is killing the trees. The goal of this case is about mitigating the tree hazards rather than preservation. In conclusion, climbing spikes may be used to reduce the risk of failure for Alder trees 101 and 102. These two Alder trees are badly diseased and in the process of decline without chance of recovery, therefore using spikes for tree climbing is not a concern for the health of Alder 101 and 102. Please reply if you have questions.

To Whom It May Concern, This report addresses concerns about a group of Red Alder trees (Alnus rubra) on the east side of the neighborhood, along 7th Ave. S, Edmonds. Many of the Alder trees have disease and structural problems. This report includes pictures and a map of the trees and their locations. The last pages are the ISA Tree Risk Assessment Forms about the subject trees. On December 21, 2020, I inspected, measured, tagged, and took pictures of eight Alder trees. Subject trees were tagged with an engraved metal strip. A couple of the Alder trees are infected with Bleeding Phytophthora (fungal) cankers near the trunk base which will lead to death of the tree. The other Alders have structural problems that require pruning to mitigate risk. The trees target 7th Avenue and a residential home. Tree Inspection List (Alnus rubra): Tag # DSH* Condition 101 15. 1 TSigns of large Phytophthora canker activity near the base. 20% live crown ratio. Tree will require removal because of advancing disease. 102 11.8", 14.0" Signs of large Phytophthora canker activity near the base of the smaller trunk. Vulnerable to windthrow if exposed. Tree will require removal because of advancing disease and canopy exposure. 103 14.5" Tree has asymmetric canopy to the east with poorly attached branching structure. Canopy pruning is recommended to reduce over -extended branches and alleviate their leverage load. 104 17.5" Tree has asymmetric canopy to the southeast. No signs of decay or disease. Some canopy pruning recommended to reduce asymmetric loading. 105 18.7" Tree has asymmetric canopy to the east and south. Leans on the neighboring tree, rubbing trunks. No signs of decay or disease. Some canopy pruning recommended to reduce asymmetric loading. 106 21.0" Tree has a 10-15 degree lean to the south with an asymmetric canopy to the south. Trunk is rubbed from neighboring tree. No signs of decay or disease. Some canopy runing recommended to reduce asymmetric loading. 107 19.5" The trunk kinks at a 30-degree lean and asymmetric canopy to the southeast. No signs of decay or disease. Some canopy pruning recommended to reduce asymmetric loading. 108 17.3" Tree has asymmetric canopy to the east. No signs of decay or disease. Some canopy pruning recommended to reduce asymmetric loading. *Diameter at Standard Height; tree trunks measured 4 '/z feet from the ground. The picture on the left is the base of Alder tree 101. The area within the yellow is diseased with bleeding Phytophthora fungal canker. The black spots are the fungal fruiting bodies. This disease will encircle the trunk and girdle the tree, leading to death. The picture on the left looks at the base of Alder trees 101 and 102. The area within the yellow shows Phytophthora disease along the crotch of tree # 102. These advancing cankers will kill both trees. There are no control methods for Phytophthora disease. 2 Alder tree 107 is pictured on the left. The yellow arrow indicates the abrupt bend in the trunk. The upper part of the trunk leans at a 30-degree angle toward the roadway. The canopy needs pruning to reduce the load at the trunk bend. The picture on the left shows the trunks of Alder trees 105 and 106. Both trees have asymmetric canopies which cause them to lean together about 10-15 degrees. The yellow arrow shows an area where the trunks are rubbing. Canopy pruning is needed to reduce the load on these two trunks and alleviate rubbing movement. 3 k. { Y ELM PL GC GC W it 0 10 20ft 101 12- 2- ELM PL W 12-162 1% Basic Tree Risk Assessment Form Client Elm Place HC Date Dec. 21. 2020 Time 10:00am Address/Tree location 626 Elm Place.
