PLANS • EXPERT TESTIMONY Member of International Society of Arboriculture and Society of American Foresters August 17, 2022 Mac Kowalczyk 4124 Lincoln Avenue NE Renton, WA 98056 RE: Tree Assessment Dear Mr. Kowalczyk: We have evaluated all trees on your property at 4124 Lincoln Avenue NE in Renton, WA. The purpose was to conduct a tree inventory, determine the condition of the trees, and identify trees for removal. An inventory was completed on July 11, 2022. Findings and Recommendations The Canopy site is a new residential subdivision on 10-acres in the City of Renton. An adjacent landowner, Mac Kowalczyk at 4124 Lincoln Avenue NE, contacted Century Communities about the potential to remove trees on his property. He was concerned about the increased risk of failure to trees on his property due to the recent clearing on the Canopy site. Removing the trees would also provide additional unobstructed views for the Canopy site. We conducted an assessment of trees on the east side of the Kowalczyk parcel. An inventory of trees on the west side of the property was also completed to account for all trees on the Kowalczyk parcel. The tree species that are proposed to be removed are native coniferous and deciduous trees. Species include Douglas-fir (Pseudotsuga menziesii), bigleaf maple (Acer macrophyllum), red alder (Alnus rubra), western redcedar (Thuja plicata), and Scouler’s willow (Salix scouleriana). The size of the evaluated trees ranges from 8 to 34 inches in diameter at breast height (DBH). The conditions of the trees vary between ‘Dead’ and ‘Good’ with most trees being in ‘Fair’ condition. A map with general tree locations is found in Attachment 1 and a list of all assessed trees is found in Attachment 2. Kowalczyk Tree Assessment Washington Forestry Consultants, Inc. Page 2 Photo 1. View of potential removal trees on Kowalczyk parcel. An inventory of the remaining trees on the lot found thirteen trees in ‘Very Poor’ to ‘Good’ condition. Those additional trees are between 10 to 43 inches DBH. Tree species are red alder, bigleaf maple, Douglas-fir, western redcedar, costal redwood (Sequoia sempervirens), horse chestnut (Aesculus hippocastanum), weeping willow (Salix babylonica), flowering plum (Prunus cerasifera), and Norway spruce (Picea abies). These trees were tallied but not numbered in the field. A total of 56 significant sized trees were found on the Kowalczyk parcel. Thirty-three (33) of those trees are in ‘Fair’ or better condition. The remaining 23 trees are in ‘Poor’ or worse conditions. The City of Renton requires at least 26 trees to be retained on the Kowalczyk parcel based on the square footage of the lot. A Routine Vegetation Management Permit would be required to remove the trees. Mr. Kowalczyk plans to remove all unhealthy trees and seven healthy trees. Healthy trees recommended for removal are numbers 12, 24, 26, 30, 31, 36, and 39. Kowalczyk Tree Assessment Washington Forestry Consultants, Inc. Page 3 Summary Fifty-six (56) significant sized trees were found on the Kowalczyk parcel in Renton, WA. Thirty- one (33) of the trees are considered healthy long-term trees. The home owner was concerned about potential tree failure between his home and the Canopy site from exposure due to recent clearing. The City of Renton Code requires 26 healthy trees to be located on the parcel. Mr. Kowalczyk is proposing to remove all trees in ‘Poor’ or worse condition and seven healthy trees. The required tree density of 26 trees is still met with the removal of the seven healthy trees. Please give us a call if you have any questions.

Note: Even healthy trees can fail under normal or storm conditions. The only way to eliminate all risk is to remove all trees within reach of all targets. Annual monitoring by an ISA Certified Arborist or Certified Forester will reduce the potential of tree failures. It is impossible to predict with certainty that a tree will stand or fail, or the timing of the failure. It is considered an ‘Act of God’ when a tree fails, unless it is directly felled or pushed over by man’s actions.
