Zone 2 is determined by slope of land and type of vegetation.
The size of the Zone 2 defensible space is determined by the kind of natural vegetation and the slope of the land. A steep slope calls for a wider perimeter than a flat area. A grassy area with only a few trees and shrubs calls for a smaller perimeter than an area dominated by shrubs and brush. The following table will help you determine the recommended distance from your structure for Zone 2 defense measures.
