Flatley Forester/Certified Arborist PN7272 AM 1021 SOUTH 32 PLACE/TRACT B July 24,2023 - Revised August 23, 2023 J and M Management Company C/O Breze Reed For Winsper Homeowners Associa=on At 1021 South 32 Place, Renton Washington 98055 and Parcel 948576 TR - B Arborist Report LOCATION OF PROPERTY Tract B is an open space parcel (PID 948576 TR-B) behind the back yard at 1021 South 32 Place. The parcel is near the NW 1/4 of the SW 1/4 of Sec=on 29 within T23N, R5E, City of Renton, County of King, State of Washington. Tract B is over one acre in size and heavily wooded with black co\onwood (Populus trichocapra) and bigleaf maple (Acer macrophyllum) trees with an understory of Himalayan blackberry and winterberry shrubs. The six trees of this report are located along the north property line of Tract B and south of 1021 South 32 Place (referred herea^er as 1021). Figure 1. Plat Map Loca=on of Parcel 12, 1021 S. 32 Pl (red shaded) and Tract B (yellow shaded) METHODS A visual tree inspec=ons occurred on Friday, July 21, 2023. Tree number 1 was found near the east property line of 1021. Tree number 2 had a whole trunk failure in early June causing damage to property at 1021. Tree numbers 3 through 6 were found within 40 feet south of the fence-line of 1021. Trunk diameter was measured for each tree, each tree trunk and root flare were sounded with mallet, condi=on noted and assigned a risk ra=ng for observable roots, trunks and branches. Table 1 provides the summary of this informa=on. 1021 S. 32 Place Page of 2 9 Figure 2. Approximate Loca=on of Trees Inspected !""#$%&’ !

It has a hollow beneath its trunk and within striking distance to both proper=es. The top has died-back about 10 feet, there is a small detached and dead hanger. Kretzschmaria disease was noted at base of tree. Table 1.

The tree is 50 feet tall which would impact property and people. Tree removal as soon as possible is recommended. Tree 3 (Tract B): This bigleaf maple should be removed immediately. At the least, the lower 6 feet of the trunk is hollow. Large stems of the upper crown have died-back and par=ally failed in the past and con=nue to drop large wood into the yard at 1021; hollow and decayed wood was seen in the top. Addi=onal trunk decay was noted above 6 feet from ground. Targets include the wood fence, backyard items, the house and people, including children. Risk ra=ng is VERY HIGH. Tree 4 (Tract B): Considered a Landmark tree due to diameter by City of Renton regula=ons, this large bigleaf maple lost its upper stems/branches from past storm damage with older sprouted branches surrounding decayed wood. The trunk has a large wound along its west face which when sounded with a mallet indicated hollow and decay for at least 8 feet from the ground. There is a large hollow below the trunk and ground with Kretzschmaria present. Risk ra=ng is HIGH because it is 15 feet from the property fence and 80 feet tall, capable of impac=ng property and people. The tree should be removed or height reduced as soon as possible. Tree 5 (Tract B): Risk ra=ng for this tree is VERY HIGH because it is 40 feet from the fence at 1021 and approximately 80 feet tall. The tree is dead, has hollows, decayed and diseased wood and sloughing bark. The tree should be removed or height reduced as soon as possible. Tree 6 (Tract B): Tree 6 is in good condi=on and does not require any ac=on at this =me. CONCLUSIONS Trees 1, 3, 4 and 5 should be removed to avoid damage to people or property because of their present condi=on, risk ra=ng and proximity to people and property. Tree 2 has already had a total trunk failure damaging property. Tree 3 is of immediate concern and should be priori=zed when considering removal. Other trees could have their heights reduced to a length shorter than the distance to the fence for wildlife habitat purposes instead of whole tree removal. Retain and protect Tree 6 when considering tree removal as it is in good condi=on.
