A commercial mower started a fire in the 2400 block of NE Diamond Lake Boulevard in Roseburg Tuesday afternoon.
At 12:40 p.m. crews were called to the site of a four-acre, wind driven, rapidly spreading vegetation fire on a vacant lot previously known as the old Champion Mill site.
Fire officials say the initial four-acre fire grew rapidly to 27 acres in size before forward spread was stopped with crews from the Roseburg Fire Department, Douglas Forest Protective Association, and Central Douglas Fire & Rescue.
In a news release, the agencies provided a reminder that there is a moderate fire danger across Douglas County.
