'YES' means the surveyor approximated an address. 'NO' means a real street address was used. ADDRESSNUMBERAddressNumberDouble8388AddressNumber refers to the number on the street address of the parcel where the tree is located.STREETStreetString5000Street refers to the name of the street where the parcel that contains the tree is located. LOCATIONLocationString2500Location refers to the tree's general physical location, and may be 'Street', 'Borderline', or 'Park or Public Space'. A location of 'Borderline' means that the surveyor could not concretely determine whether the tree was located in the public right-of-way, or the tree belonged to the adjacent private property. In such cases, future investigation by staff will be needed to determine whether the tree is public or privately owned.X_COORDX_COORDDouble8388X_COORD means 'X coordinates' and refers to the east/west coordinate location of the tree in feet, using Projected Coordinate System NAD_1983_StatePlane_Michigan_South_FIPS_2113_IntlFeetY_COORDY_COORDDouble8388Y_COORD means 'Y coordinates' and refers to the north/south coordinate location of the tree in feet, using Projected Coordinate System NAD_1983_StatePlane_Michigan_South_FIPS_2113_IntlFeet.WARRANTYDATEWarrantyDateDate3600WarrantyDate refers to the date that the warranty is up for a newly planted tree.OWNERSHIPOwnershipString2000Ownership refers to the owner of the tree.MAINTENANCEMaintenanceString5000Priority 1 RemovalThese trees have defects that cannot be cost effectively or practically treated, have a high amount of deadwood, and pose an immediatePriority 2 RemovalThese trees are not as great of a liability as Priority 1 Removals, being smaller and/or less hazardous, although they are also recommended for removal. Davey recommends that they be removed as soon as possible.Priority 3 RemovalTrees designated for Priority 3 Removal do not pose a public hazard and are small, dead, or poorly formed. Smaller dead trees and failed transplants are in this category. Large trees in this category are generally poorly sited, of inferior quality, and pose little to no threat to the community.Priority 1 PruningTrees in this category need pruning to remove hazardous deadwood limbs greater than four inches in diameter and/or have broken, hanging, or diseased limbs.Priority 2 PruningThese trees need pruning to remove hazardous deadwood limbs greater than two, but less than four, inches in diameter.Large Tree Routine PruningTrees in this category have characteristics that could become risks if not corrected. Deadwood limbs are less than two inches in diameter.Small Routine Tree PruningThis category includes small growing trees that can generally be maintained from the ground, i.e., crabapples, serviceberry, dogwood, etc., and other trees 20 feet or less in height.Training PruningThis category includes trees under 20 feet tall with correctable structural problems or minor amounts of deadwood that pose minimal threat of personal injury or property damage. Inexpensive pruning at this stage significantly affects the future of these trees. Young trees in this category that will be large at maturity generally require an annual pruning or inspection.PlantData on vacant planting sites is collected using policies on minimum tree lawn width for mature tree size, spacing between trees, distances from intersection and traffic safety signs, and the presence of utilities.Stump RemovalStumps are identified separately since they may not be removed at the time of a tree removal.Maintenance refers to the maintenance need of each individual tree, classified into one of the following recommended maintenance categories.INSPECTInspectString2500Yesmost trees in this category require an annual inspection for several years. A healthy tree obviously impacted by recent construction serves as a prime example. This tree will need annual evaluations to assess the impact of construction on its root system. Another example would be a tree with a defect requiring additional equipment for investigation.NoNo annual inspection needed.Inspect indicates whether or not the tree should have annual inspection.CONDITIONConditionTreeHealthString2500Excellent100% to 90% condition class. The tree is nearly perfect in condition, vigor, and form. This rarely used category is generally applicable to small DBH trees or shrubs that have been recently transplanted and are well established. It also applies to large trees that have established themselves successfully in the landscape.Very Good89% to 80% condition class. Overall, the tree is healthy and satisfactory in condition, vigor, and form. The tree has no major structural problems, no mechanical damage, and may only have insignificant aesthetic, insect, disease, or structure problems.Good79% to 61% condition class. The tree has no major structural problems, no significant mechanical damage, may have only minor aesthetic, insect, disease, or structure problems, yet is in good health.Poor40% to 21% condition class. The tree appears unhealthy and may have structural defects such as codominant stems, severe included bark, or severe trunk and/or limb decay. A tree in this category may also have severe mechanical damage, crown dieback, or poor vigor threatening its ability to thrive. Trees in poor condition may respond to appropriate maintenance procedures, although these procedures may be cost?prohibitive to undertake.Critical20% to 1% condition class. The tree has a major structural problem that presents an unacceptable risk, has very little vigor, and/or has an insect or disease problem that is fatal and, if not corrected, may threaten other trees on the property.Dead0% condition class. This category refers to dead trees only.Condition indicates the current state of a tree's health, structural soundness, overall shape, and growth rate. Symptoms of poor condition include discoloration, decay, dieback, decreased internodal length, and/or disfigured or necrotic stems or roots. To some extent, condition class is also a reflection of the life expectancy of the tree. Crown development, trunk condition, major branch structure, twig growth rate, insects/diseases, and root condition are all considered. In general, the condition of each tree is recorded as one of the following categories adapted from the rating system established by the International Society of Arboriculture® (ISA).CONDITIONDATEConditionDateDate3600ConditionDate was the date when the ConditionTreeHealth was assessed.DBH2009DBH2009Integer4100DBH2009 means the 'diameter at breast height' in 2009.

Trees with saw log potential have at least 8' of wood usable for these purposes.COMMENTSCommentsString10000Comments are any general comments referring to the tree.DATAORIGINDataOriginString2000DataOrigin refers to the original source of the tree's data.CreatedUserCreatedUserString4000CreatedUser refers to the person who first created the attribute.DateCreatedDateCreatedDate3600DateCreated was the date that the tree attribute was first created.DateModifiedDateModifiedDate3600DateModified was the date that the attribute was last modified.ModifiedUserModifiedUserString4000ModifiedUser was the person who last modified the attribute.SHAPEShapeGeometry400Feature geometry.ESRICoordinates defining the features.gisenterprise.PSOWNER.Tree_Has_AttachedDocsRelationship20100204Urban Forestry and Natural Resources Planningmailing and physical address100 N Fifth Ave, 4th Floor, PO Box 8647Ann ArborMI48107USA734-794-6430City of Ann Arbor System PlanningDavey Resource Group performed a public tree inventory for the City of Ann Arbor from February-April 2009, using a combination of handheld computer-based mapping (GIS), GPS locators connected to the handheld computer, and field judgment to best determine information about species, condition, maintenance requirements, and location.
