Indiana 811 is a private, nonprofit, statewide organization which has the responsibility to manage the “call before you dig” process for Indiana. It is your responsibility to make sure that you and/or your landscaper make this call to locate all utilities and sewers at the digging site at least two full working days before you dig. Visit www.811NOW.com or call 811 to schedule a locate of your digging project.
Below is a list of trees suggested for planting in the parkway, however if sewers are located in your parkway, we would advise against planting at that site. These trees were selected for placement along the road because they are less likely to destroy sidewalks or asphalt with shallow root systems, but even these root systems eventually will grow into and cause backups in nearby sewers. Also, to help ensure a healthy tree, planting in parkways narrower than 6’ wide is not recommended and trees planted under power lines must have maximum height at maturity of less than 25’.
Most of these trees have crowns around 20’ wide at maturity, helping to prevent overhang into the street and damage to large vehicles, such as snow plows and garbage trucks. They have also shown some tolerance to road salt. Pyrus calleryana, commonly known as Bradford or Cleveland Pear, is not on this list. It is now considered an invasive species and no longer acceptable as a landscape tree.
