Regional context, not property-specific evidence. The federal wildfire occurrence database lists 2 fires within 5 miles of Ottawa in 2020, burning about 10 acres in total. None started naturally. None was 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:

• Woodburn
• Smyrna

Every fire recorded in Clarke County

The eight closest, with where each one stands in the county. Distances are straight-line, computed from the Geographic Names Information System coordinates.
