Trees growing too close to power lines can cause damage to Oncor facilities and interrupt service to the community. Oncor follows generally accepted industry guidelines and best practices to have minimal impact on the health of trees pruned. Oncor’s standards are based on several factors: the minimum safe working distance for a utility worker, how much trees and conductors sway in high winds and the ability of limbs to break and fall on lines. Oncor can never prune enough to prevent all tree-related outages; however, a well-managed tree pruning program can drastically reduce outages due to trees and provide a safer environment for utility workers and the public.

Customers in the immediate vicinity of the tree trimming area will receive a bright green door hanger notifying them work will begin soon. Oncor will proceed in a professional manner with any necessary pruning and clean-up.

This map indicates the general area Oncor will be trimming. Customers with questions concerning the work may call 1-800-518-2375 to speak to an Oncor representative or visit
