|Minimum Planting Distances|
|from SMUD pad mounted equipment (such as a transformer mounted on a concrete pad):||8 feet|
|from a building foundation:||15 feet|
|from walks and driveways:||6 feet|
|from an air conditioner:||6 feet|
|from a fence:||6 feet|
|from a utility offset (such as an underground line, pipe or cable):||6 feet|
|from a utility overhead (such as an overhead power line):||20 feet|
|from a swimming pool:||12 feet|

|* To calculate the planting distance between different size trees, add the distances between each species in the column and divide answer in half.
Example: the distance between a Red Maple (large tree) and Amur Maple (small tree) is calculated: 25 feet + 15 feet = 40 feet ÷ 2 = 20 feet. The distance between these two different size trees should be 20 feet.
