Flatley Forester Certified Arborist/Municipal Specialist #7272 AM Arborist Report Weston Heights Homeowners Association Critical Area Wetland Buffer Tree Removal February, 2021 Purpose City of Renton regulations requests property owners to submit an arborist report to perform tree removal within designated critical areas and obtain a permit referred as, “CRITICAL AREAS EXEMPTION.” The report includes information about trees so that City Planning staff can determine if tree removal falls within exemption guidelines in order to issue a permit. This report for the Weston Heights Homeowners Association (HOA), provides information for trees the HOA is concerned with that might impact the homes surrounding a wetland area. The report contains the information that the HOA can use in ﬁling Critical Areas Exemption submittals. Description of the Site •General description: 12 homes comprise the subdivision which are located in the northeast area of the city limits. 9 homes can be found east of Duvall Avenue NE, on NE 7th Court. And, 4 homes are along Orcas Court NE, south of NE 7th Place. A wetland area, identiﬁed as Tract B, is in the middle of the subdivision and drains to the south into the Ellis Park HOA wetland. In addition, Tract A is a common area (public water and storm drainage easement) along Duvall and Tract C is a stormwater facility at the end of Orcas Court. Tract D is part of NE 7th Court serving as a public easement for access and water utility. •Legal Description: SW Quarter Section, Section 11, Township 23 N, Range 5 N, City of Renton, King County, Washington •Trees: The trees of concern are all located within Tract B. They are all red alder tree species (Alines rubra) except a Siberian willow clump, all native to the area. The trees were tagged with bright pink ﬂagging and numbered according to the inventory table below. Diameter at Breast Height (DBH) was measured at 54 inches above ground level. Each tree’s approximate location is shown on the subdivision map attached. Table one provides the inventory of trees. Photographs of trees and descriptions are included below. Tract B Tract B is approximately 1.64 acres (71,345.70 sq.ft.) in size. It contains a sparse population of trees and shrubs dominated by Himalayan blackberry (Rubus armeniacus). The main overstory species is red alder with nearly every tree in very poor to dead condition. All the trees of concern can be found along the perimeter of the wetland designated area. The area along the wetland designation is known as the wetland buffer. The wetland buffer extends from the parcel boundaries for a distance of 50 feet towards the wetland. Trees of Concern Live, healthy trees do not represent a signiﬁcant risk of failure under normal weather conditions. Such trees are considered to be in excellent, very good or good condition. On the other hand, trees that are dead, contain large pockets of decay, and have severe lean can be considered in poor or very poor condition. A large gradation exists between very poor and excellent conditions of trees. Typically, trees are evaluated according to some risk and how they might affect property or people according to their risk rating. For example, trees in the open represent a low risk because if they fail there is no speciﬁc targets for them to strike, damage or hurt people. Trees along a busy street can represent a higher risk due to the presence of people, vehicles and structures. Weston HOA Arborist Report of 1 13 The trees in this report are found in the wetland buffer adjacent to developed properties which contain fences, houses, other structures and, the intermittent presence of people. Four trees are dead and within 10 feet of property boundaries. Three trees are in poor to very poor condition. Should they fall or parts of them fail they have a very high probability of damaging property or injuring people. It is recommended the following trees be removed or reduced to a safe height immediately due to their high risk of damage to property and injury to people. Summary The 7 trees examined were either completely dead, dying and contained extensive decay and hollows. The dead trees have been dead for approximately ﬁve years as evidenced by the sloughing, brittle bark. Fungal bodies were observed on several trunks, an indication of internal decay. They have lost some of their branches; several older trunks had fallen onto the wetland delineation fence at three locations, pointing to increased risk of failure in the standing trees. One resident indicated that branches from one or more trees landed in his backyard. All trees are very close to adjacent fences, yards, houses and structures, having a high probability of failing and striking these objects or injuring people. Based upon the high likelihood of the trees falling/failing and striking and damaging structures or injuring residents it is recommended the trees be removed immediately. The following pages provide site photographs of each tree as well as three maps to assist locating the property at the: •Regional level •Neighborhood level •Subdivision level - trees are shown as 1 through 7 corresponding with Table 1 and site photographs.
