Wildland Fire Rating Zones for Humboldt County.  Digitized using Humboldt County 
Safety Element Map, July 1979.  Original map scale: 1 inch = 2 Miles.  
Data may not be accurate for large scale overlays.  

Below is a section from Humboldt County General Plan Volume 1 Framework Plan, Adopted 12/10/1984.

3230	Wildfire

Humboldt County exhibits extreme diversity in it potential for destructive fire, from nil to 
extreme in severity classification.  The wildfire hazard in the County has been analyzed using 
the methodology of the California Department of Forestry Report to the Governor's Office of Planning 
and Research (1973), modified to account for conditions not included in their procedure.  This 
method takes into account climate, the fuel potential of the vegetation and topography.

CDF's fire hazard methodology as applied to Humboldt County and the distribution of zones is 
shown on the Wildfire and Flood Hazard Map.  This distribution generally reflects a moderate 
to high rating on the western portions of the County where the fuel potential is high but the 
climate is damp.  The extreme ratings are generally in the drier eastern portions of the County 
or in very steep terrain.

Policy application of the fire ratings is by referring to the map of Wildland Fire and Flood.  
The Planning Department determines which applications should be reviewed by the appropriate fire 
protection agency, and considers their response in the approval and requirements for development 
application.  This method reduces the risk to structures and their occupants, as well as the 
threat to surrounding wildland vegetation.  This risk which wildland occupants cause others is 
also reduced by the requirement of fire safety measures.

The standards that are used as guidelines for development reviewed by the Planning Department to 
reduce the hazard of fire are the CDF "Fire Safe Guides" (CDF, 1980).  Other County standards are 
listed in Title III, Division 2 Subdivision Regulations, and the newest edition of the Uniform 
Building Code.  The Fire Safe Guides are applied with some discretion due to competing policy 
concerns such as adequate road width for emergency vehicles versus increased erosion from wider road widths.

Horizontal positional accuracy explanation:
Please note the accuracy of GIS map data varies from location to location in the County. This GIS system is useful for planning purposes but should not be relied upon to determine property, zoning or general plan designation boundaries or be used in any way for project design. All GIS data should be verified before it is materially relied upon for property or project planning. In urban areas the GIS map data maybe inaccurate by as much as 50 feet in any direction. In rural areas the map data may be inaccurate by as much as 400 feet in any direction.  This is a general accuracy disclaimer.  Data may be more or less accurate depending on source informaton and digitizing methods.
