SLCFPD has adopted the California Department of Forestry (CDF) Fire Safe Standards as fire protection guidelines for existing structures and new development in areas exposed to wildland interface fires as recommended in the Cobb and Middletown Area Plans of 1989. The basis for fire service standards rely on studies of the District, standards and practices of Fire Officers, LAFCO Sphere of influence studies, the Lake County General and Community Plans, the Insurance Services Office standards and testing of the Fire Protection System and the National Fire Protection Association Standards.
