The Fuel Modification Unit is responsible for the approval of a landscape plan for structures located in the Fire Hazard Severity Zones.  The process of approval consists of reviewing aspects such as structure location and type of construction, topography, slope, amount and arrangement of vegetation, and overall site settings.  Our objective, through this approval plan process, is to create defensible space necessary for effective fire protection of homes in the Fire Hazard Severity Zones.
