(a) Trees adjacent to and within street rights-of- way. The following provisions shall regulate the planting of trees adjacent to and within street rights-of-way.
(1) Applicability.
A. Whenever a new use is established or the conversion of a use occurs, the requirements of this subsection shall be applicable to the entire lot.
B. Whenever a principal building is constructed, reconstructed or structurally altered by one or more additions, the total of which increases the floor area by more than 10 percent, the requirements of this subsection shall be applicable to the entire lot on which the building is located. If there is more than one building on a lot, this provision shall apply when the total floor area for all the buildings is increased by more than 10 percent.
C. If any provision of this chapter would preclude the planting of one or more trees adjacent to the right-of-way, the trees that cannot be planted adjacent to the right-of-way shall be planted within the right-of-way according to the provisions of paragraph 1158.02(a)(3) titled Placement of trees within street rights-of-way. Trees that cannot then be planted in conformity with the provisions of that paragraph may be omitted.
(2) Required tree planting adjacent to street rights-of-way.
A. Trees shall be planted at a minimum ratio of one tree for every 40 feet of lot frontage.
B. Trees shall be planted adjacent to street rights-of-way.
C. Large and medium trees shall not be spaced closer than 30 feet apart nor closer than 14 feet of a building. Small trees shall not be spaced closer than 16 feet apart nor closer than (8) feet of a building. Where screening is appropriate or required, this spacing may be reduced, provided the trees are planted according to the provisions of subsection 1161.01(h), Screening, and are of a variety suitable for screening.
D. At street intersections, trees shall not be located within 70 feet of the intersection of curb lines (or pavement edge where curbs do not exist) when planted along arterial streets, within 50 feet when planted along collector streets, nor within 30 feet of the intersection of local streets. (City Engineer is to calculate distances.)
E. Trees shall be placed to avoid interference with the construction, maintenance and operation of public and private utilities and services above or below ground as determined by the utility companies and the City Engineer.
(3) Placement of trees within street rights-of-way.
A. A tree planting permit shall be obtained from the City Forestry Division; or for new developments, placement and species of trees in street rights-of-way shall be provided on construction drawings.
B. No trees shall be planted where the width of the area between a curb and a sidewalk is less than four (4) feet. If no sidewalk exists, the width between a curb and a right-of-way line shall be at least nine (9) feet. Trees shall not be located within two (2) feet of a street curb or edge of pavement where a curb does not exist, within two (2) feet of a sidewalk, nor within six (6) feet of a right-of-way line where a sidewalk does not exist. (City Engineer or Engineer's designee is to determine how close a tree should be to the street pavement where a curb does not exist.)
C. At street intersections, trees shall not be located within 70 feet of the intersection of curb lines (or pavement edge where curbs do not exist) when planted along arterial streets, within 50 feet when planted along collector streets, nor within 30 feet of the intersection of local streets. (City Engineer or Engineer's designee is to calculate distances.)
D. At the intersection of a street and a drive or at the intersection of a street and an alley, trees shall not be located within 15 feet of the edge of the drive or the right-of-way line of the alley.
E. Large and medium trees shall not be spaced closer than 30 feet apart nor closer than 14 feet of a building. Small trees shall not be spaced closer than 16 feet apart nor closer than eight (8) feet of a building.
F. Trees shall be placed to avoid interference with the construction, maintenance and operation of public and private utilities and services above or below ground as determined by the utility companies and the City Engineer.
G. No tree shall be planted within 10 feet of a utility pole.
(b) Trees on private property for residential uses.
(1) Applicability. Whenever a building containing a duplex or multi-family residential use is constructed, reconstructed or structurally altered by one or more additions, the total of which increases the floor area by more than 10 percent, the requirements of paragraph (2) shall be applied to the entire lot on which the building is located. If there is more than one (1) building on a lot, this provision shall apply when the total floor area for all the buildings is increased by more than 10 percent.
(2) Required tree planting for residential uses.
A. Trees shall be planted at the minimum ratio of one (1) tree for every 500 square feet of total building coverage of the lot. Existing trees with a minimum trunk diameter of six (6) inches measured six (6) inches above established grade may be substituted for new trees at the ratio of one (1) existing tree for every two (2) new trees. Where residential uses are combined with other uses, the building coverage shall be determined on the basis of the greatest amount of residential floor area of any floor that is wholly or partially devoted to a residential use. Except for trees planted for screening purposes, trees planted to fulfill the requirements of Subsection 1158.02(a) titled Trees adjacent to and within street rights-of-way, and Subsection 1158.02(b) titled Trees on private property for residential uses, may be used to fulfill the requirements of this subsection.
B. Large and medium trees shall not be located closer than 14 feet to a building. Small trees shall not be located closer than eight (8) feet to a building.
C. Trees shall not be located within four (4) feet of a right-of-way-line.
D. At street intersections within the right-of-way or within eight (8) feet of the right-of-way, trees shall not be located within 70 feet of the intersection of curb lines (or pavement edge where curbs do not exist) along arterial streets, within 50 feet along collector streets, or within 30 feet along local streets. In instances where two different types of streets intersect, the location of the tree shall be determined by the type of street adjacent to the proposed tree. (City Engineer or Engineer's designee is to calculate distances.)
