The purpose of the report is to satisfy City requirements regarding tree retention and protection associated with the proposed redevelopment of the property. My assignment is to prepare a written report on present tree conditions, which is to be submitted to the City with the development application materials. This report covers all of the criteria set forth under the City of Edmonds tree regulations (EMC 23.10.060 Tree retention associated with development activity). The required retention is 25% of significant trees. A significant tree means a tree that is at least six inches in diameter at breast height (DBH) as measured at four and one-half feet from the ground. Date of Field Examination: November 3, 2021 Description Three significant trees were identified and assessed on the subject property. A tree summary table is attached which provides detailed information for each assessed tree. One of the subject trees is a boundary line tree located on the south property line. Four trees have been recently removed from the property. It is my understanding the City has authorized this removal. Subject trees were identified in the field with a numbered aluminum tag attached to the lower trunk. These tag numbers correspond with the tree numbers on the attached summary table and maps. There are no neighboring or off -site tree issues associated with this property other than the one boundary line tree. None exist within a proximity of property lines. Methodology Each tree in this report was visited. Tree diameters were measured by tape. The tree heights were measured using a Spiegel Relaskop. Each tree was visually examined for defects and vigor. The tree assessment procedure involves the examination of many factors: • The crown or canopy of the tree is examined for current vigor/health by examining the foliage for appropriate color and density, the vegetative buds for color and size, and the branches for structural form and annual shoot growth; and the overall presence of limb dieback and/or any disease issues. The trunk or main stem of the tree is inspected for decay, which includes cavities, wounds, fruiting bodies of decay (conks or mushrooms), seams, insect pests, bleeding or exudation of sap, callus development, broken or dead tops, structural defects and unnatural leans. Structural defects can include but are not limited to excessive or unnatural leans, crooks, forks with V-shaped crotches, multiple attachments. Page 3 Layton Tree Consulting LLC November 8, 2021 Arborist Report — 304-310-312 Daley Street • The root collar and exposed surface roots are inspected for the presence of decay, insect damage, as well as if they have been injured or wounded, undermined or exposed, or the original grade has been altered. Based on these factors a determination of condition is made. Judging Condition The three condition categories are described as follows: Good —free of significant structural defects, no disease concerns, minor pest issues, no significant root issues, good structure/form with uniform crown or canopy, foliage of normal color and density, average or normal vigor, will be wind firm if isolated or left as part of a grouping or grove of trees, suitable for its location Fair — minor to moderate structural defects not expected to contribute to a failure in near future, no disease concerns, moderate pest issues, no significant root issues, asymmetric or unbalanced crown or canopy, average or normal vigor, foliage of normal color, moderate foliage density, will be wind firm if left as part of a grouping or grove of trees, cannot be isolated, suitable for its location Poor— major structural defects expected to cause fail in near future, disease or significant pest concerns, decline due to old age, significant root issues, asymmetric or unbalanced crown or canopy, sparse or abnormally small foliage, poor vigor, not suitable for its location Judging Retention Suitability Not all trees necessarily warrant retention. The three retention suitability categories as described in ANSI A300 Part 5 (Standard Practices for the Management of Trees During Site Planning, Site Development and Construction) are as follows: Good — trees are in good health condition and structural stability and have the potential for longevity at the site Fair — trees are in fair health condition and/or have structural defects that can be mitigated with treatment. These trees may require more intense management and monitoring, and may have shorter life -spans than those in the "good" category. Poor —trees are in poor health condition and have significant defects in structure that cannot be mitigated with treatment. These trees can be expected to decline regardless of management. The species or individual tree may possess characteristics that are incompatible or undesirable in landscape settings or be unsuited for the intended use of the site. Observations The subject trees are described as follows. Page 4 Layton Tree Consulting LLC November 8, 2021 Arborist Report — 304-310-312 Daley Street Tree #1 is a young redwood tree. It has been topped in the past or the top broke out at roughly 8-feet above ground. It has regenerated three new tops. Structure is poor. Forked tops are likely to split off in the future. Retention suitability is rated as poor. Tree #2 is a young to semi -mature cultivated variety of Japanese flowering cherry. It is located close to the alley and existing structure. It has developed goo form and is of good vigor. Tree #3 is a young cultivated variety of Norway maple. It is located close to the south property line. Vigor is good. It has an asymmetric canopy to the north. Canopy growth is restricted to the south by the newer building, see picture below. Crown reduction pruning is needed on the north side to better balance the crown or canopy. Discussion/Recommendations Tree #1 has poor structural form. Prior topping has compromised structural stability. Forked tops are likely to fail (split off) in the future. Removal and replacement are recommended. Tree #2 will be compromised by alley improvements and the demolition of the existing improvements. Removal and replacement are recommended. The attached tree plan map indicates the actual dripline of the subject tree to be retained or protected. The information on the tree plan map and in this report can be used by the project architect to create the final tree retention plan sheet for City submittal if necessary. Position the tree protection fencing around Tree #3 as shown on the attached map. The recommended protection area or critical root zone is 6-feet from the trunk face on the north side. Maintain the existing grade within this area. Tree protective fencing shall be a minimum height of three feet, visible and of durable construction; orange polyethylene laminar fencing is acceptable. Maintain the barrier for the duration of the project. Prune back the canopy on the north side to uniformly shape it and provide adequate construction clearance. Any roots damaged during site work outside of the tree protection area shall be pruned at sound tissue prior to backfilling or finishing areas. Sound tissue is where the root is undamaged and the bark is completely intact with the root. This will help roots to seal off potential decay and allow them to sprout new growth. Any disturbed areas near protected trees shall be watered weekly during the dry season of June through September. This will help to create a favorable environment for new root growth and reduce the overall stress associated with root loss and disturbance. Finish the landscape within the dripline by cutting and/or hand -pulling unwanted vegetation and applying a +/- 4-inch layer of organic mulch. Keep irrigation trenches, large plantings or other improvements outside of the dripline areas. Page 5 Layton Tree Consulting LLC November 8, 2021 Arborist Report — 304-310-312 Daley Street Tree Protection Measures The following guidelines are recommended to ensure that the designated space set aside for the preserved trees are protected and construction impacts are kept to a minimum. Standards have been set forth under EMC 23.10.070 Tree protection measures during development. Please review these standards prior to any development activity. • Tree protection fencing shall be erected prior to moving any heavy equipment on site. Doing this will set clearing limits and avoid compaction of soils within root zones of retained trees. • Excavation limits shall be laid out in paint on the ground to avoid over excavation and unnecessary damage. • Authorized work or excavation within the driplines of protected trees shall be monitored by a qualified tree professional so necessary precautions can be taken to decrease impacts to tree parts. • To establish sub grade for foundations, curbs and pavement sections near the trees, soil shall be removed parallel to the roots (away from tree trunks) and not at 90-degree angles to avoid breaking and tearing roots that lead back to the trunk within the drip -line. Any roots damaged during these excavations shall be exposed to sound tissue and cut cleanly with a saw. • Areas excavated within the driplines of retained trees shall be thoroughly irrigated weekly during dry periods. • Preparations for final landscaping shall be accomplished by hand within the drip -lines of retained trees. Large equipment shall be kept outside of the tree protection zones at all times. Tree Replacement 25% of significant trees are required to be retained. Tree #3 is proposed for retention, equating to 33% retention. The removal of Trees #1 and #2 will require replacement. Two replacement trees for each are required, totaling four new replacement trees. Consult with your City planner to determine if any tree replacement is required for trees previously removed from the property. Minimum sizes for replacement trees shall be: One -and -one -half -inch caliper for deciduous trees; and six feet in height for evergreen trees. Page 6 Layton Tree Consulting LLC November 8, 2021 Arborist Report — 304-310-312 Daley Street Arborist Disclosure Statement Arborists are tree specialists who use their education, knowledge, training and experience to examine and assess trees, recommend measures to enhance the beauty and health of trees, and attempt to reduce the risks associated with living near trees. Clients may choose to accept or disregard the recommendations of the arborist, or to seek additional advice. Arborists cannot detect every condition that could possibly lead to the structural failure of a tree. Trees are living organisms that grow, respond to their environment, mature, decline and sometimes fail in ways we do not fully understand. Conditions are often hidden within trees and below ground. Arborists cannot guarantee that a tree will be healthy and/or safe under all circumstances, or for a specified period of time. Likewise, remedial treatments, like any medicine, cannot be guaranteed. Treatment, pruning and removal of trees may involve considerations beyond the scope of the arborist's services such as property boundaries, property ownership, site lines, disputes between neighbors, and other issues. Arborists cannot take such considerations into account unless complete and accurate information is disclosed to the arborist. An arborist should then be expected to reasonably rely upon the completeness and accuracy of the information provided. Trees can be managed, but they cannot be controlled. To live near trees is to accept some degree of risk. The only way to eliminate all risk associated with trees is to eliminate all trees.
