While city crews try to repair that giant hole where a water trunk line failed on Coldwater Canyon Avenue over the weekend, another water main break has claimed a fire engine. The engine got stuck after a six-inch main broke this morning about 5:20 a.m. near the intersection of Hartsook Street and Bellingham Avenue, east of Laurel Canyon Boulevard and south of Magnolia Boulevard. Hartsook is closed, says the DWP.
