If you’re heading southbound on California SW through the 3300 block – south of Prost, The Bohemian, Spiro’s, and the almost-complete Madison Heights townhouse project – it’s slow going because of those four huge cherry-picker trucks working on trimming tree branches away from power lines. City Light has had major tree work going in West Seattle for almost a year now; SCL’s Scott Thomsen just confirmed to WSB that this is city work — “JTS Inc. is working there for us with a city arborist. They’ve been out in West Seattle for the past three weeks. They’ll be working in that area for about another month.”
