The Butte County Board of Supervisors Tuesday is scheduled to consider adjusting the county’s fire service agreement with Cal Fire as it wrestles with rising costs, with recommendations to close a fire station in Chico and remove several rural stations from a program that keeps them staffed year-round. The board also will consider starting the process of forming a county-wide fire protection district, which could result in a dedicated funding source for the Butte County Fire Department. The formation of such a fire district would require approval from voters and the Local Agency Formation Commission.
