On Friday evening just after 9 p.m., a fire was reported in the 2300 block of Mariner Square Drive. That address is the location of Barnhill Marina, a floating home Marina on Alameda’s Northern waterfront. Neighbors immediately posted about it to social media, and KTVU posted about the fire to Twitter with a video. The KTVU post stated: “We are smelling the fumes,” from the fire. KTVU’s newsroom is located at Jack London Square, just across the Estuary.
