As someone that was riding the second Engine on scene, I can say that your aerial map isn't correct, the house was at the corner of Scarborough Station Road and Beachwood Way. The call originally came out as a Vehicle Fire and was then changed to a Structure Fire when the fire spread and eventually involved the entire 3 car garage, both the first and second floors, and the roof. The heat played a large factor in the amount of manpower needed as it was very hot today and extremely humid. On scene there was already one Rescue from Briarcliff and 2 Rescue/Engines also from Briarcliff. This did not "strip down a large portion of the county if another fire or major EMS incident were to occur" as all the companies that responded, besides all of the BMFD apparatus, whose Ladder is currently OOS requiring the use of Ossining's Ladder 42, were only a small fraction of their overall companies and coverage areas. Westchester is a large county and would have been fine had another fire or major EMS incidednt occured. Overall, it was a good burn. Everyone worked well, it was well organized and everyone did their jobs. The biggest problem of the incident was the heat and humidity, which put many on scene on the sidelines for longer than normal, but everyone was able to work through it with very few people needing medical attention to deal with dehydration, overexertion, etc. Here's a picture I snapped after the majority of the fire was under control/knocked down. The garage to the right was where the fire originally began, spread to the middle garage and eventually blew out reaching 4 cars, 3 parked to the right and 1 to the left of where the picture was taken, which are some 35 feet away from the structure. A few more spots popped up and the whole frame of what was the garage was knocked completely down, can't speak on the condition of the interior not scene here as I did the majority of my work during the initial attack before aiding with exterior and clean up operations.
