We maintain a minimum distance from utility lines, which we have marked out and delineated so we know where they run. Tree roots grow where water is available - in cases where they interfere with utilities, it’s often initially caused by a leaking pipe, and the roots follow the water into the pipe. Proper slow drip “deep watering” is provided to mitigate this risk to encourage the roots to follow the water down to the natural water table. Here’s how we make sure to avoid this issue: Here’s how we make sure to avoid this issue: Utility Check: We work with utility providers to identify the location of underground communication, electric, and gas utilities so we can avoid them. There are no records for sewer line markings, but we always identify the sewer vent before approving a tree location. Without locating the sewer, we do not plant trees. Basin Placement: Trees are planted at least 3 feet away from communication, electric, and gas lines and at least 5 feet away from sewers. If a sewer vent cannot be located, a tree will not be planted unless the tree is a request and there is a vent perhaps hidden in the garage. Deep root watering: Slow drip watering (from our water bags) allows water to penetrate slowly into the soil and encourages roots to grow deep rather than horizontally, increasing the potential of roots getting into the sewer. Sewer lines: A tree will find the leak if the property has a leaking pipe. In most cases, roots grow into the pipe unless there is an existing opening or water is emitted. Soil Compaction: When trees are planted, they are done so where the soil is augered/loosened straight down. The soil compaction around the augered zone means roots are discouraged from growing into the area.
