§ 102-34. Street tree spacing.

(a)

The spacing of street trees will be in accordance with the three species size classes listed in section 102-33, and no trees may be planted closer together than the following: small trees, 15 feet; medium and large trees, 25 feet; except in special plantings designed and approved for unusual effect, or as approved by both the city engineer and city planner.

(b)

No street trees shall be planted closer than 25 feet from any street corner, measured from the point of nearest intersecting curbs or curblines.

(c)

For the purpose of this subsection the term "tree lawn" shall be defined as the area between the curb or edge of pavement and the public sidewalk or right-of-way line, if no sidewalk is present. The location of street trees within the tree lawn shall be as follows:

(1)

Street trees shall be centered in the tree lawn between the curb and public sidewalk. If no sidewalk is present, trees shall be centered between the curb and a line 6.5 feet inside and parallel to the right-of-way line of the street.

(2)

For streets without curbs, street trees shall be centered in the tree lawn between the future proposed curb line, as established by the city engineering department, and the public sidewalk. If no sidewalk is present, trees shall be centered between the future proposed curb line and a line 6.5 feet inside and parallel to the right-of-way line of the street.

(3)

In residential neighborhoods a minimum clear tree lawn width of five feet should be maintained for all street trees, unless approved by both the city engineer and the city planner.

(d)

The city may enter into contractual arrangements with the owners of private properties for the planting and maintenance of trees where there is insufficient space between the curb or curbline and the sidewalk or right-of-way line. In such instances, the city may establish a new line of street trees on private properties, with property owner approval. Whether such planting is desirable or not, and the selection of the tree species and specific planting locations, shall be the determination of the city. When such plantings occur, the initial costs of trees and their planting shall be as determined by mutual agreement. The proper care of such trees for a period of three years thereafter shall be the responsibility of the city. Following such three-year period, the trees shall become the responsibility of the property owners.
