Landscaping and Clearance Requirements

Clearance Requirements

Transformer, Switches and Pedestals

No structures, fences or shrubs can be placed within 10’ of the front and 5’ from the sides of an electric transformer or switch. There should be a vertical clearance of 22’ from the top of the final grade at the transformer location. All pedestals must have at least 3’ clearances.

Electric Meters

Electric meters must be placed so that there is no obstruction for meter reading, meter testing or other maintenance, allowing 2' and 4' front clearances. Meters must be located in an unlocked area so they can easily be accessed for maintenance and testing.

Overhead Electric Power Lines

The Electric Utility maintains clearances along overhead electric power lines. Trimming is done on an approximate three-year cycle. Before pruning, trimming or cutting down trees near power lines, or to report trees interfering with power lines, call (630) 420-6187. If requesting tree trimming services near utility, lines, please allow 48 hours.

Landscaping Requirements

Recommended species for growing around electric facilities are short, compact, conical, columnar or pyramidal plants.  Remember to factor size at maturity when planning to ensure plants do not grow into the clearance requirements stated on this page.
