The trimming should be completed in approximately 3 months. The WCA crew has logos on their trucks as well as on their uniforms. They also have a letter from Light & Water explaining who they are and what they are doing to hand to customers. They will also put door knockers out to help them gain access to the back easements. If there are any questions regarding the tree trimmers, please call (626) 812-5184. Thank you for your cooperation with this matter.
