The purpose was to determine the number of trees retained, evaluate their health, and make any recommendations for cultural care. A field assessment was conducted on November 3, 2022. Findings and Recommendations The tree list on the approved site plans indicated 49 trees were planned to be retained onsite. Tree species include Douglas-fir (Pseudotsuga menziesii), flowering cherry (Prunus spp.), western redcedar (Thuja plicata), black cottonwood (Populus trichocarpa), bigleaf maple (Acer macrophyllum), and bitter cherry (Prunus emarginata). A total of 50 trees were retained on the Edenfield site, one tree more than planned. Tree #3, a 17-inch DBH Douglas-fir, that was identified as a removal tree was retained. The tree is located within 4-feet of the new sidewalk. Over 40% of this tree’s root system has been impacted from the grading and installation of the sidewalk. It is expected that the health of the tree will decline from the disturbance and may need removal in the future. All the remaining trees retained onsite were properly protected from construction disturbance and will be quality long-term trees. Recommended cultural care is to cover the tree protection areas with 3 – 4 inches of quality mulch. This will prevent weed growth and help the soil from drying out during the summer months.

Summary Our inspection found 50 trees retained on the Edenfield site, one additional tree than planned. The additional tree has had a large portion of its root system impacted from construction. Its health will more than likely decline in the next 3 years and may need to be removed when no longer healthy. All other trees will be quality long-term trees in the landscape. Please give us a call if you have any questions. Respectfully submitted, Galen M. Wright, ACF, ASCA Joshua Sharpes ISA Bd.

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.
