A. 
It shall be unlawful to plant, or cause to be planted, any street tree, without providing a minimum clearance between such tree and any other street tree on the same side of the street, computed as follows:
1. 
Trees of same type. The minimum clearance between the trunks of any two (2) street trees of the same type shall be that clearance provided in Section 235.140.
2. 
Trees of different types. The clearance between the trunks of any two (2) street trees of different types shall be determined by adding the minimum clearances shown for each type of street tree concerned, as shown Section 235.140 and dividing the sum thereof by two (2).
3. 
Existing trees. The minimum clearance from any existing street tree not shown in Section 235.140 shall be determined by the Street Commissioner, so that the existing street tree, at its maturity, will not come in conflict with or overlap the street tree to be planted, at its maturity.
[R.O. 2012 §235.170; CC 1979 §30-28; Ord. No. A-2260 §§5, 11, 7-9-1965]
