Introduction American Forest Management was contacted by KP Development Group and was asked to compile an ‘Arborist Report’ for a development at 1825 NE 38th St in the City of Renton. The parcel number is #3345700220. Our assignment is to prepare a written report on the current condition of significant trees on the subject parcels and any right-of-way or neighboring trees that may be impacted by the future development of the property. Date of Field Examination: .......................................................... February 23rd and 26th, 2018 2. Description 128 significant trees were identified on the property. According to City of Renton code, a significant tree is a tree with a caliper (trunk diameter measured 4-1/2’ above the ground) of at least 6” or an alder or cottonwood tree with a caliper of at least 8”. Trees planted within the most recent ten years qualify as significant trees, regardless of the actual caliper. There are also 12 neighboring trees that may be impacted by the proposed development. These 12 trees were included in this report. All subject trees have been identified by the surveyor with a white piece of flagging with a number written on it. Significant trees that were not surveyed were approximately located and tagged with a numbered aluminum tag attached to the lower trunk of the tree. Field tree tag numbers correspond with attached Tree Condition Summary Table and attached copy of the site survey. The tree summary table provides descriptive data for all assessed trees, including drip-line measurements. 3. 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 of the tree is examined for current vigor. This is comprised of inspecting the crown (foliage, buds and branches) for color, density, form, and annual shoot growth, limb dieback and disease. The percentage of live crown is estimated for coniferous species only and scored appropriately. • The bole or main stem of the tree is inspected for decay, which includes cavities, wounds, fruiting bodies of decay (conks or mushrooms), seams, insects, bleeding, callus development, broken or dead tops, structural defects and unnatural leans. Structural defects include crooks, forks with V-shaped crotches, multiple attachments, and excessive sweep. • The root collar and roots are inspected for the presence of decay, insects and/or damage, as well as if they have been injured, undermined or exposed, or original grade has been altered. February 28th, 2018; Updated 10/8/2018 1825 NE 38th St - Renton Page 3 AMERICAN FOREST MANAGEMENT, INC. Based on these factors a determination of condition is made. The four condition categories are described below based on the species traits assessed: Excellent – free of structural defects, no disease or pest problems, no root issues, excellent structure/form with uniform crown or canopy, foliage of normal color and density, above average vigor, it will be wind firm if isolated, suitable for its location 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 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 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 A ‘viable’ tree is a significant tree that a qualified professional has determined to be in good health, with a low risk of failure due to structural defects, is wind firm if isolated or remains as part of a grove, and is a species that is suitable for its location. Trees considered ‘non-viable’ are trees that are in poor condition due to disease, age related decline, have significant decay issues and/or cumulative structural defects, which exacerbate failure potential. The attached tree map indicates the ‘condition’ of the subject trees found at the site. 4. Observations General species concerns are described below. For information on specific trees, see the attached tree table. Big leaf maple Big leaf maple is the most common species on the property. Most are healthy and viable. The majority have co-dominant trunks which is typical for the species. The most common defects observed were poor attachments between co-dominant trunks, dead branches, and asymmetrical crowns. Ivy is growing up the trunks of most of the trees. For some of the big leaf maples, the entire trunks is covered in ivy. The big leaf maple trees range in condition from poor to good. Douglas fir There are many mature (over 80 years old) Douglas fir trees. They are located throughout the property. No natural regeneration of Douglas fir trees is occurring and there are very few Douglas fir trees under 20 years old on the property. Most have good taper and full crowns. The most common concerns were structural issues such as forked tops, crooked February 28th, 2018; Updated 10/8/2018 1825 NE 38th St - Renton Page 4 AMERICAN FOREST MANAGEMENT, INC. trunks or asymmetrical crowns. English ivy is growing up the trunks of most of the Douglas fir trees on the property. Overall, most of the Douglas fir trees are in good condition and are viable. Western red cedar The majority of Western red cedar trees on the property are healthy and viable. Most have good trunk taper and full crowns. Ivy is growing up the trunks of all of the Western red cedars. Tree #1099 is a young Western red cedar. The top half of this tree is dead. This tree is in poor condition and is non-viable. With the exception of tree #1099, all of the Western red cedar trees on the property are viable. Sitka spruce There are some young and semi-mature Sitka spruce trees in the southwest area of the property. Ivy growing up the trunks of these trees. Conditions range from fair to good. All are viable. Leyland cypress There are Leyland cypress trees that were planted on the south perimeter of the property. Most have forked tops and two are leaning south. Conditions range from fair to good. All are viable. Cascara There are four cascara trees scattered on the east side of the lot. They are all over- mature. One tree, #876, has severe decay and is on poor condition. The other three are and fair condition and are viable. Red alder Red alder is a minor species on the property. The most common concern is leaning trunks with poor trunk taper. The red alders range in condition. Ivy is growing up the trunks of most of the trees. Tree #1235 is in poor condition. This tree has a small live crown and decay. The other red alder trees on the subject property are in fair condition and are viable. 5. Discussion The extent of drip-lines (farthest reaching branches) for the subject trees can be found on the tree summary table at the back of this report. The Limits of Disturbance (LOD) measurements can also be found on the tree summary table. The LOD measurements are based on species, age, condition, drip-line, prior improvements, proposed impacts and the anticipated cumulative impacts to the entire root zone. These should be referenced when determining retention feasibility. The City of Renton code requires that tree retention priority should be focused on landmark trees and significant trees that form a continuous canopy. There are eight landmark trees on the subject property. The City of Renton defines a landmark tree with a trunk greater than 30" at 4.5' above ground. The attached tree table notes which trees qualify as landmark trees. The short lived hardwood species such as red alder and cascara are low priority for retention. Retention efforts should be focused on the healthy big leaf maple, Western red cedar and Douglas fir trees. February 28th, 2018; Updated 10/8/2018 1825 NE 38th St - Renton Page 5 AMERICAN FOREST MANAGEMENT, INC. The entire property has any ivy infestation. Ivy becomes a problem for trees when it grows to a large size and grows up into the tree crown. The leaves of the ivy cover branches inhibiting the development of tree leaves and thereby reducing the trees photosynthetic processes, causing stress and ultimately decline. The weight of the ivy is also problematic. Oftentimes, the weight of the ivy will cause stems or branches to fail when they become over-loaded and cannot support the additional weight. A few trees in the study area have recently failed from being over-loaded by the weight of the ivy. The probability of more failures is high. If left alone, the ivy will eventually over take the subject trees, causing them all to fail prematurely. If the subject trees are to be maintained in the landscape for another 20 years or so, the ivy will need to be cut away from the trees. To kill the ivy vines, the vines are cut back from the base of the tree a few feet. Then the ivy is cut a few feet up the tree trunk, removing the cut portions. Once the ivy is severed, it will die. The ivy will eventually decay and fall out of the trees. Given the current infestation, this will take a few years. As much of the ivy as possible should be pulled off of the trees to remove additional weight, thereby increasing structural stability. 6. Tree Retention A total of 128 significant trees were identified on the subject property. The City of Renton requires retention of 30% of all the viable significant trees on R-8 zoned sites. The six trees in poor condition were not included in the calculation. Trees in Critical Areas and buffers as defined in RMC 4-3-050 are excluded from the retention calculation. According to the site map provided by the Client 20 trees are located in the 25 foot buffer and Critical Area. Including the 6 trees in poor condition, a total of 26 trees were excluded from the retention calculation. Trees 922, 998, 1055, 1056, 1044, and 1061 are identified as Landmark Trees and are not proposed for retention. Tree Calculation based on 102 healthy, viable trees outside of Critical Areas and Buffers Minimum amount of trees that must be retained on site: 31 trees. 7. Tree Replacement For planting and maintenance specifications, refer to Section 4-4-130 of the Renton Tree Ordinances. Total number of healthy, viable trees, outside of Critical Areas and buffers that are proposed to be reatined: 17 trees. Total number of trees to be replaced: 31 - 17 = 14 trees. Total number of required replacement inches: 14 x 12 = 163 inches Number of replacement trees required (Minimum of 2" caliper trees required for replacement): 163 / 2 = 82 trees (Rounded up from nearest tenth) February 28th, 2018; Updated 10/8/2018 1825 NE 38th St - Renton Page 6 AMERICAN FOREST MANAGEMENT, INC. The number of replacement trees could change depending on the caliper of trees selected for replacement. 8. 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. Refer to the City of Renton Code 4-4-130- 9. Protection Measures During Construction for more information. They are also included at the end of this report. • Tree protection barriers shall be initially erected at 5’ outside of the drip-line prior to moving any heavy equipment on site. • Tree protection fencing shall only be moved where necessary to install improvements, but only as close as the Limits of Disturbance, as indicated on the attached plan. • Excavation limits should be laid out in paint on the ground to avoid over excavating. • Excavations within the drip-lines shall be monitored by a qualified tree professional so necessary precautions can be taken to decrease impacts to tree parts. A qualified tree professional shall monitor excavations when work is required and allowed up to the “Limits of Disturbance”. • To establish sub grade for foundations, curbs and pavement sections near the trees, soil should be removed parallel to the roots 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 should be exposed to sound tissue and cut cleanly with a saw. Cutting tools should be sterilized with alcohol. • Areas excavated within the drip-line of retained trees should be thoroughly irrigated weekly during dry periods. • Preparations for final landscaping shall be accomplished by hand within the drip-lines of retained trees. Plantings within the drip lines shall be limited. Large equipment shall be kept outside of the tree protection zones. There is no warranty suggested for any of the trees subject to this report. Weather, latent tree conditions, and future man-caused activities could cause physiologic changes and deteriorating tree condition. Over time, deteriorating tree conditions may appear and there may be conditions, which are not now visible which, could cause tree failure. This report or the verbal comments made at the site in no way warrant the structural stability or long term condition of any tree, but represent my opinion based on the observations made. Nearly all trees in any condition standing within reach of improvements or human use areas represent hazards that could lead to damage or injury. Please call if you have any questions or if we can be of further assistance. Sincerely, February 28th, 2018; Updated 10/8/2018 1825 NE 38th St - Renton Page 7 AMERICAN FOREST MANAGEMENT, INC.
