Purpose of Report This report provides an arboricultural evaluation of trees located on the commercial property at 1222 Bronson Way North, Renton, WA. The purpose is to: • Document tree condition and species • Identify potential hazards to site users • Support tree management decisions including pruning, retention, and removals • Assist with compliance for any permitting requirements with the City of Renton 2. Methodology A ground-based visual inspection was conducted in accordance with the ISA Tree Risk Assessment Best Management Practices (Level 2). Observations included: • Species identification • Diameter at Breast Height (DBH) measurements • Canopy health • Structural integrity • Signs of pest damage, decay, or vandalism • Assessment of site usage and potential targets beneath tree canopies Trees were documented with photographs and cross-referenced to a site map using numerical IDs. 3. Site Description The property is an active commercial strip mall with multiple businesses including restaurants, salons, and educational facilities. The site experiences heavy pedestrian and vehicle traffic, particularly around parking areas adjacent to the tree line. Ten (10) trees were identified and assessed. They are distributed around the site perimeter and planting strips, with some located near driveways, walkways, and parking stalls. 4. Tree Inventory and Observations Site: Penta Commercial LLC, 1222 Bronson Way North, Renton, WA • Tree #1 – Douglas Fir or Western Hemlock (23” DBH) This tree is completely dead. It displays clear signs of vandalism, including a series of drilled holes at the lower trunk. The canopy is entirely defoliated. Risk Level: High • Tree #2 – Blue Atlas Cedar (21” DBH) This tree is approximately 95% dead and exhibits significant scorch damage. While no drill holes were found, it is located adjacent to Tree #1 and may have been affected by chemical contamination through shared root zones. Risk Level: High • Trees #3 through #7 – Douglas Fir (28–32” DBH) These are large, mature, and well-structured fir trees located in the northern parking strip. They are in excellent overall health with minor deadwood and no major defects observed. These trees do overhang a parking area and should be monitored as part of routine maintenance. Risk Level: Low • Tree #8 – Box Elder (~22” DBH) This tree is in poor condition with evident structural decay, including significant heart rot. A section of the tree has already failed and fallen. Risk Level: High • Tree #9 – Box Elder or Hybrid Maple (~14” DBH) This tree appears heavily overpruned and displays signs of root zone damage, likely from repeated foot traffic and parking lot compaction. Decline is advanced. Risk Level: High • Tree #10 – Box Elder (~20” DBH) This tree is heavily overgrown with English ivy, which obscures full structural inspection. Based on similarity in location, species, and pruning history to Trees #8 and #9, it may be experiencing early decline. No major failures were observed at the time of inspection. Risk Level: Moderate 5. Risk Discussion Trees 1, 2, 8, and 9 present immediate safety concerns due to death or advanced structural decline. Tree 10, while partially obscured by ivy, shows similar maintenance history and soil compaction as trees 8 and 9, suggesting it may be on a comparable decline trajectory. Trees 3 through 7 are healthy Douglas firs. While located above parking areas, they present no current structural defects and are considered low risk with routine monitoring and maintenance. 6. Recommendations Removals (High Risk) • Tree 1: Dead and vandalized • Tree 2: Functionally dead, likely poisoned • Tree 8: Structural decay • Tree 9: Compromised root and trunk structure Further Evaluation / Monitoring • Tree 10: Remove ivy to evaluate trunk and branch structure; reassess risk Preservation and Routine Care • Trees 3–7: Prune for clearance and deadwood as needed; inspect periodically Arborist Report 6 / 14 Penta Commercial LLC Arborist Report Dec 9, 2025 1 Project: Penta Commercial LLC Date: Nov 20, 2025, 9:47 AM Creator: Eric Ledford Tags: #1 2 Project: Penta Commercial LLC Date: Nov 20, 2025, 9:48 AM Creator: Eric Ledford Tags: #1 3 Project: Penta Commercial LLC Date: Nov 20, 2025, 9:48 AM Creator: Eric Ledford Tags: #1 4 Project: Penta Commercial LLC Date: Nov 20, 2025, 9:48 AM Creator: Eric Ledford Tags: #1 Arborist Report 7 / 14 Penta Commercial LLC Arborist Report Dec 9, 2025 5 Project: Penta Commercial LLC Date: Nov 20, 2025, 9:49 AM Creator: Eric Ledford Tags: #1 6 Project: Penta Commercial LLC Date: Nov 20, 2025, 9:50 AM Creator: Eric Ledford Tags: #1 7 Project: Penta Commercial LLC Date: Nov 20, 2025, 9:56 AM Creator: Eric Ledford Tags: #2 8 Project: Penta Commercial LLC Date: Nov 20, 2025, 9:56 AM Creator: Eric Ledford Tags: #2 Arborist Report 8 / 14 Penta Commercial LLC Arborist Report Dec 9, 2025 9 Project: Penta Commercial LLC Date: Nov 20, 2025, 9:58 AM Creator: Eric Ledford Tags: #1, #2 10 Project: Penta Commercial LLC Date: Nov 20, 2025, 10:01 AM Creator: Eric Ledford Tags: #3 11 Project: Penta Commercial LLC Date: Nov 20, 2025, 10:02 AM Creator: Eric Ledford Tags: #3 12 Project: Penta Commercial LLC Date: Nov 20, 2025, 10:02 AM Creator: Eric Ledford Tags: #4 Arborist Report 9 / 14 Penta Commercial LLC Arborist Report Dec 9, 2025 13 Project: Penta Commercial LLC Date: Nov 20, 2025, 10:04 AM Creator: Eric Ledford Tags: #4 14 Project: Penta Commercial LLC Date: Nov 20, 2025, 10:04 AM Creator: Eric Ledford Tags: #5 15 Project: Penta Commercial LLC Date: Nov 20, 2025, 10:05 AM Creator: Eric Ledford Tags: #5 16 Project: Penta Commercial LLC Date: Nov 20, 2025, 10:06 AM Creator: Eric Ledford Tags: #6 Arborist Report 10 / 14 Penta Commercial LLC Arborist Report Dec 9, 2025 17 Project: Penta Commercial LLC Date: Nov 20, 2025, 10:07 AM Creator: Eric Ledford Tags: #6 18 Project: Penta Commercial LLC Date: Nov 20, 2025, 10:07 AM Creator: Eric Ledford Tags: #7 19 Project: Penta Commercial LLC Date: Nov 20, 2025, 10:08 AM Creator: Eric Ledford Tags: #7 20 Project: Penta Commercial LLC Date: Nov 20, 2025, 10:10 AM Creator: Eric Ledford Tags: #8 Arborist Report 11 / 14 Penta Commercial LLC Arborist Report Dec 9, 2025 21 Project: Penta Commercial LLC Date: Nov 20, 2025, 10:11 AM Creator: Eric Ledford Tags: #8 22 Project: Penta Commercial LLC Date: Nov 20, 2025, 10:14 AM Creator: Eric Ledford Tags: #9 23 Project: Penta Commercial LLC Date: Nov 20, 2025, 10:14 AM Creator: Eric Ledford Tags: #9 24 Project: Penta Commercial LLC Date: Nov 20, 2025, 10:14 AM Creator: Eric Ledford Arborist Report 12 / 14 Penta Commercial LLC Arborist Report Dec 9, 2025 25 Project: Penta Commercial LLC Date: Nov 20, 2025, 10:16 AM Creator: Eric Ledford Tags: #10, ivy 26 Project: Penta Commercial LLC Date: Dec 9, 2025, 6:14 AM Creator: Eric Ledford Arborist Report 13 / 14 Penta Commercial LLC Arborist Report Dec 9, 2025 Certification Statement Certification Statement Certification: I, Eric B.
