Regional context, not property-specific evidence. The federal wildfire occurrence database lists 505 fires within 5 miles of Rio Hondo between 1992 and 2020, burning about 4,615 acres in total. None started naturally. 40 were recorded as arson. Distance is straight-line from the map coordinates, so a fire counted here may appear on a neighbouring settlement's page as well.

The most recent of them, most recent first, with the day each was reported and the service that recorded it.

Settlements close enough to share some of these fires:

• Gage
• Bell Gardens
• Downey Road
• Laguna
• McCampbell
• Vinvale

What was taken out: Clay, Sand and Gravel, Construction, Stone, Crushed/Broken. Distance is straight-line from the map coordinates, so a quarry counted here may appear on a neighbouring settlement's page as well.
