This polygon shapefile depicts boundaries of Agricultural Land Soils for the County of Humboldt, California. This coverage classifies Soils according to their content, including clay, gravel, sand, silt and mixtures thereof. These data were derived from the "Soils of Western Humboldt County" map, a joint effort by the University of California Davis and Humboldt County (McLaughlin and Harradine, 1965) that rated Soils in Humboldt County for overall quality.
The Humboldt County Planning and Building Department is responsible for protecting the public health, safety and welfare via building permit review and inspections consistent with California model codes as well as planning and development review and approval consistent with the county's General Plan. This Department oversees the Advance Planning Division, which is responsible for the Humboldt County's Geographic Information System (GIS) that is utilized by other County Departments; many federal, state and local agencies; and the general public. This coverage can be used for basic applications such as viewing, querying, and map output production, or to provide a basemap to support graphical overlays and analyses of geospatial data.

This polygon shapefile depicts boundaries for Airport Noise Contours at the Arcata-Eureka Airport in the County of Humboldt, California. These Contours are displayed at both the 60 and 65 Community Noise Equivalent Levels (CNELs), representing equal levels of noise exposure for each Level. Aircraft noise is a significant factor in land use planning around airports. The objectives of compatible land use planning are to encourage land uses that are generally considered to be incompatible with airports (such as residential, schools, and churches) to locate away from airports and to encourage land uses that are more compatible (such as industrial and commercial uses) to locate around airports. The Federal Aviation Administration (FAA) has been actively supporting programs to minimize noise impacts. The Arcata-Eureka Aiport is located in McKinleyville, California and offers commercial air service to Humboldt, Del Norte and Mendocino Counties and is served by 1 commercial airline.

This polygon shapefile depicts boundaries of Parcels over which the County of Humboldt, California holds authority. This coverage includes all unincorporated areas, as well as cities/incorporated areas. Assessor's Parcels are based upon the legal property descriptionsand each Parcel is identified by an Assessor's Parcel Number (APN), which is an 8 digit number separated by dashes (e.g. 049-103-12). The first 3 digits represent the Assessor's mapbook containing the Parcel (Book 049 in the above example). The next 2 digits represent the page number within that mapbook (Page 10 in the example). The next digit represents the block number on that page (Block 3 in the example). The last 2 digits represent the Assessor's Parcel Number on that block (12 in the example). A Parcel is a piece of real property under a defined ownership, or it can be a lot in a subdivision. County governments administer and legislate through the creation of and maintenance of land records that are associated with a Parcel of land. Thus the Parcel is often the vital administrative unit of local government. Parcel maps must meet the requirements of the General Plan and all applicable laws and ordinances. Parcel maps are alternately called tax maps, plat maps, plot maps and assessor maps.

This polygon shapefile depicts the boundaries for Community Service Districts and Spheres of Influence in unincorporated areas of the County of Humboldt, California, to which basic services like water, sewage collection and street lighting services are provided by the County. Because Counties often consist of large and diverse geographical areas, providing a consistent and adequate service level across all areas can be difficult. The Community Services District Law (Government Code §61000-61850) was created to provide an alternate method of providing services in unincorporated areas. Property owner pay taxes to the Community Service District instead of the County for the services provided. Taxes are calculated upon assessed value of the land and improvements and placed on the property tax bill.

This polygon shapefile depicts the Alquist-Priolo Earthquake Fault Zones and Fault Traces as shown on the official Alquist-Priolo Earthquake Fault Zones Map of the Arcata North United States Geological Survey quadrangle map. The dataset is comprised of polygons and lines that form regulatory zone boundaries (Alquist-Priolo Earthquake Fault Zones) and Fault Traces of areas where surface fault rupture has previously occurred, or where local topographic, geological and geotechnical conditions indicate a potential for permanent ground displacements, such that mitigation by avoidance would be required (as stated in Public Resources Code Section 2621.5). The Alquist-Priolo Earthquake Fault Zoning Act's main purpose is to prevent the construction of buildings used for human occupancy on the surface Trace of active Faults. Before a new project is permitted, Cities and Counties require a geologic investigation to demonstrate that proposed buildings will not be constructed on active Faults.
