The proposal includes the pruning of 42 trees throughout the property for the purpose of maintaining building clearance, pedestrian clearance, road clearance, hazard mitigation, and general tree health/aesthetics. In addition, two (2) trees would be cabled to mitigate potential tree parts failure hazards due to poor tree structure. The work is estimated to take 2.5 days, would be performed during regular business hours, and would not block any public roadways. The following equipment will be used on sight for the duration of the project: dump truck, woodchipper, bucket truck, chain saws, pole saws, and hand saws. The project site is mapped with protected slopes (slopes with grades that exceed 40%) and sensitive slopes (slopes with grades betwe en 25% and 40%). CRITICAL AREA: Protected and Sensitive Slopes EXEMPTION JUSTIFICATION: RMC 4-3-050C.3.c Agricultrual, Harvesting, Vegetation Management: iii. Dangerous Trees: Removal of non-native invasive ground cover or weeds listed by King County Noxious Weed Board or other government agency or dangerous trees, as defined in Chapter 4-11 RMC which have been approved by the City and certified dangerous by a licensed landscape architect, or certified arborist, selection of whom to be approved by the City based on the type of information required. Staff Comment: The proposal includes the maintenance of existing trees within an existing multi -family apartment development. The proposed pruning and cabling would maintain the health of the existing trees with the intent that the proposed maintenance activities would avoid removal of the trees in the future.

The apartment complex parcel is located within several critical areas. This report was created to describe recommended pruning and mitigation within these areas. 44 trees are included on this report. The trees are located sporadically around community. Please see attached Site Plan and corresponding pin numbers for approximate locations. The tree assessment was performed on September 15th, 2021. The tree assessment was regarding the present conditions, integrity, and future expectations of the trees. The trees were assessed with speciﬁc focus on the potential risk to the property, residents, and visitors. Assignment (and any limiting factors) The assignment was a Level 2 Basic Risk Assessment of the trees within the parcel. This limited visual assessment was performed solely from ground grade and was completed to provide recommendations for future action. A Plus was requested to assess all trees on site. A report was created regarding recommendations for safety concerns, potential impact to the property, and to distinguish if the trees pose future risks. 2000 Lake Washington management intends to reduce the risk of future tree failures and/or structural damage on site by acquiring arborist services for mitigation of trees. 2000 Lake Washington management intends to plant replacement trees according to the City of Renton's regulations for tree retentions standards following mitigatory tree care. There were no limitations to assessment.

Many trees on site are contacting the buildings, almost contacting the buildings, or possess limbs likely to be contacted by passing vehicles. Clearance pruning will utilize minimal pruning practices to clear the aforementioned items. For all trees, cuts are not expected to exceed 3 inches in diameter. Clearance pruning is important tree maintenance to upkeep in order for properties to be in compliance with local ﬁre codes and to reduce the likelihood of property damage, insect infestation, or rodent infestation. Crown reductions are being recommended for select trees. The trees included on this report for crown reductions have become large for their species and are expected to experience failures if retained as is. Trees of the included species can be prone to splitting failures at their respective sizes. The trees will be reduced back to a point where the likelihood of future failure will be reduced. Crown reductions remove weight from the ends of branches back to a healthy, growing lateral branch, which will form a new crown. The process reduces long, heavy, or overextended branches, as well as removing any branches with signiﬁcant defects. Reduction cuts are not expected to exceed 4 inches in diameter. Weight reduction pruning is being recommended for select trees possessing heavy limbs expected to fail in a heavy loading event or under normal circumstances. Reducing weight at the ends of these limbs will reduce the likelihood of them failing. Static steel cable installation is being recommended for select trees to prevent a future splitting failure and to encourage future integrity.. The purpose of this is to support weak crotches/codominant leaders with included bark. (This type of structure is viewed as a defect as it an increase the likelihood of splitting failures along the included bark union). Upon visual inspection of the trees included on this report, they were recommended for the aforementioned pruning and arborist services. These recommendations were given with focus on reducing the likelihood of property damage and/or personal harm to residents/visitors. 2000 Lake Washington management intends to plant replacement trees according to the City of Renton’s standard, following mitigatory tree care.
