“HISTORIC TREE.” A tree that has been specifically designated by the City Council to be historic.
“IMPERVIOUS MATTER.” Building and structure footprints, areas of pavement, compacted gravel, or other compacted areas that by their dense nature do not allow the passage of sufficient oxygen and moisture to support and sustain healthy root growth.
“LARGE TREE.” Any tree over 50 feet at maturity.
“MEDIUM TREE.” Any tree between 30 and 50 feet at maturity.
“PARK TREES.” Trees, shrubs, bushes, and all woody vegetation in public parks and all areas owned by the city, or to which the public has free access as a park.

“SPECIMEN TREE(S).” A tree or group of trees considered to be important community assets due to their unique or noteworthy characteristics or values. A tree may be considered a “SPECIMEN TREE” based on its size, age, rarity, or special historical or ecological significance as determined by the Tree Commission. Examples include large hardwoods (e.g., oaks, poplars, maples, etc.), and softwoods (e.g., pine species), in good or better condition, with a diameter of 24 inches or greater, and smaller understory trees (e.g., dogwoods, redbuds, sourwoods, persimmons, etc.), in good or better condition, with a diameter of ten inches or greater.

“UNSAFE TREE.” For a tree to be considered unsafe, one of the following criteria must apply:

(a) A structural defect that predisposes the tree to failure (e.g., dead tree, trunk decay, dead branches, V-crotches; etc.); and
(b) A target such as a structure, road, walkway, campsite, or other area where property exists or people reside. In urban areas, target areas are almost always in close proximity to trees; or
(2) A tree that is otherwise structurally sound but which interferes with the routine activities of people. Interferences include obstructions, sight distance problems for motorists, buckling of sidewalks, attracting lighting, or interference with utilities.
“VEGETATION.” Any living plant or group of plants such as a tree, shrub, or ground cover.
