trees as either Open Grown or Stand Grown the average crown radius measured in feet. 1Multiple Stem DBH is the trunk diameter of all stems measured at 4.5-feet above ground level, in inches. 2DBH Trees with multiple stems at or near ground level are converted to a single DBH shown according to the requirements in the City of Tigard code. 3C-Rad is the average crown radius measured in feet. 4Effective canopy cover is the average tree canopy area (in square feet) calculated as follows: Double the canopy of open grown trees = (Average Tree Canopy Spread / 2)2 x p. 5Heritage Tree identifies whether or not the tree is a Heritage Tree (either Y for yes or N for no). 7Condition is the numerical condition rating (0-3) as defined in the Tigard Urban Forestry Manual: DEADWOOD PESTS DECAY major scaffold branches Infested major conks and cavities The tree has good to excellent health and structural stability; the tree will be more resilient to development impacts, and will require less frequent management and monitoring after development than a tree rated as a "2". twig and branch dieback Infested one to a few conks; small cavities small twigs Minor present only at pruning wounds 8Preservation is the numerical suitability for preservation rating (0-3) as defined in the Tigard Urban Forestry Manual: CONSIDERATIONS The tree is a "hazard tree" as defined in chapter 18.120 of the Tigard Development Code and "hazard tree abatement" as defined in Chapter 18.120 in the Tigard Development Code cannot be completed in a manner that results in tree retention consistent with tree care industry standards. The tree is dead, in severe decline, or declining but may still be retained if desirable for wildlife or other benefits because it is not considered a "hazard tree" or "hazard tree abatement" could be performed. The tree has average health and/or structural stability that could be alleviated with treatment; the tree will be less resilient to development impacts and will require more frequent management and monitoring after development than a tree rated as a "3".
