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: 8 feet
  • from an air conditioner: 8 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): 30 feet
  • from a swimming pool: 15 feet
  • from a septic system: 15 feet
  • between trees*: 25 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.
