At 1430 hours the Rescue was dispatched to assist 90 on a house fire at 1062 Monticello Lane. First arriving units encountered a well involved basement fire and made a hard push down the basement interior stairs as well as the side C bilco steps from the outside. Rescue 50 arrived and stretched a line into the first floor and began opening up the walls to keep the fire from spreading further upward. Crews had to use caution due the floor being spongy in areas because of the amount fire in the basement. Engine 502 was also called to the scene to assist with manpower. 50 crews worked in the basement removing items from the heavily cluttered area. All 50 units cleared at 1630 hours.
