We are finalizing our update to the Fire Study for Chino Hills State Park. Of these two causes, what do you think the most common identifiable cause for a fire ignition is in our hills?
The results were: 43% arson and 57% automobile.
Thanks to those that participated in our poll. Arson is the leading cause of known fire ignitions. Between 1914 and 2018, there were 151 documentable fires and 15 of those were confirmed arson!
