On Dec 12th Valhalla and North White Plains Fire Departments we’re dispatched to 1 Roosevelt Dr for a chimney fire. Upon arrival of Engine 84 it was found that the top part of the chimney had a large amount of ash and ember burning. The members checked for possible fire inside the house, with nothing found. Tower Ladder 49 was used to check that the fire at the top of the chimney was completely extinguished.
