The Glenbrook Fuels Reduction Project is a forest fuels reduction project that will create a shaded fuel break on between 161 and 200 acres of overstocked forest within the defense zone of the wildland urban interface in the region. The proposed project is designed to modify fire behavior and reduce flame lengths to 4 feet during 90th percentile fire weather. This type of forest thinning project will enable firefighters to engage in structure protection in the event of a wildland fire.
