These Online Mapping Applications enable viewing of Geographic Information Systems (GIS) Mapping Data covering all of Humboldt County.  Key datasets include Parcels, Zoning, Land Use, Highways and Roads, Streams, USGS Topo Quads and Aerial Photography.  Datasets have been compiled from various sources including State and Federal Agencies.  Up to date Parcels and Roads data have been provided by City of Eureka GIS, City of Arcata GIS and Humboldt County Planning.  Digital Aerial Photography provided by City of Eureka GIS (2007) and USDA FSA Aerial Photography Field Office: County image mosaic for Humboldt, CA (NAIP 2005).


All applications display map services with basic layers, functionality and search options. Basic functionality includes map zooming and panning, identify, measurement, layer control,  and map printing.  Search by address or parcel number is available in all applications.   Other search functions are also available depending on the application.

Please note the accuracy of the GIS Parcel Lines and other data shown in this system varies from location to location in the County. This GIS system is useful for planning purposes but should not be solely relied upon to determine property, zoning or general plan designation boundaries or be used in any way for project design.    Humboldt County Community Development Services (HCCDS) makes no guarantee of the accuracy or completeness of this data.  It has not been fully reviewed for accuracy and is intended to be used for planning purposes only.  HCCDS assumes no liability or responsibility in the use,  or misuse, of this system.  While every effort has been made to assure the accuracy of this information, it should be understood that it does not have the force and effect of law, rule, or regulation. Should any difference or error occur, the law will take precedence.

Important notes about this new system.

  1. This is a work in progress and we welcome your feedback about the system. If you have comments about the system, please click here.

  2. While parcel boundaries and maps are available for all parcels in Humboldt County including incorporated areas, this system only displays land use and zoning designations for parcels in the unincorporated areas of Humboldt County, not parcels in the cities of Arcata, Blue Lake, Eureka, Fortuna, Ferndale, Rio Dell, or Trinidad.  Contact each city for General Plan Land Use and Zoning Designations for city parcels.
