Back Lot Lines

ABC Tree trimmer goes skyward the old-fashioned way on back lot.

ABC Tree trimmer goes
skyward the old-fashioned way
on back lot.



Here’s what you are likely to experience in an older neighborhood served by back lot lines. Since your neighborhood has been so hard hit because of big trees distrupting service and breaking conductor and poles, you are likely to get service back later than neighborhoods with front lot service or with underground residential service.


First the circuit is taken out, typically by opening a cutout. Then grounds are put on the circuit and flagged. Next, the tree trimming crews are brought in to clean trees and limbs and out of the right of way. Then any broken lines are spliced. Then when the lines are cleared, the grounds are removed and the cutout closed. Then if the main feeder is live, customers will be out of the dark.


We called Project Manager Tony Maldinado with ABC Professional Tree Services, Inc., who was working just such a line. We followed him to the job site and arrived just in time to catch one of their tree trimmers climbing a gigantic deciduous tree with broken and damaged limbs. He was getting the limbs away from the back lot pole and transformer. Normally a trimmer would throw a line over a high limb and then climb directly to the limb that needed work. With so many tree limbs weakened and damaged, the tree trimmers went from limb to limb, testing each as they went. Because the tree crews were unable to locate their trucks in back lots, the climbers were using their climbing hooks and hand lines to cut away these problem limbs.


General Foreman Javier Espinosa told me that this Pasadena neighborhood had a lot of big trees and received much more tree-related damage than did the city of Galveston. Javier shared that ABC’s home offices are right here in the area. Asked where he was working , Javier said, “ They move me every day.”
