Street:	The street name of the mailing or frontage address of the property.
Side:	Indicates the location of the tree at that address. Location types include: Front, Side, Median, Rear, and Sub Street Median.
Tree:	All sites at an address (trees, vacant planting sites, or stumps) are assigned a tree number. Tree numbers begin with 1 at each address and increase in the direction of increasing addresses on that side of the street.
On Address:	Physical location of the site.

Species:	Trees are identified by their genus and species (botanical name). Cultivar names (cultivated variety) are used only when it is necessary to differentiate them from similar species or cultivars.
DBH:	Tree diameters are measured at breast height: approximately 4.5 ft above ground level. Diameters are measured in ranges: 0-6”, 7-12”, 13-18”, 18-24”, 24-30”, and >30.”
Height:	Tree heights are estimated to the top of the crown. They are grouped in ranges of 0-15’, 16-30’, 31-45’, 46-60’, and >60’.
