Airport Land Use Commission

The Airport Land Use Commission (ALUC) was formed on May 19, 1981 and is the entity responsible for ensuring that land uses adjacent to public airports are compatible with airports. In Humboldt County the Board of Supervisors act in the capacity as the ALUC. Typically the ALUC meets on a as-needed basis during regular Board of Supervisor Meetings. The decisions made by the ALUC are guided by the Airport Land Use Compatibility Plan.

The current Airport Land Use Compatibility Plan (ALUCP) was prepared in 1993. The ALUC is currently preparing an updated ALUCP. The draft 2020 ALUCP was released in July 2020 for public comment. Both the current and the draft ALUCP can be found below.

Interactive Mapping Tools

Due to the scale of maps in the current and draft ALUCPs it may be difficult to ascertain how the ALUCPs affects various properties. To aid in interpreting how both the existing and draft ALUCPs affects property, an interactive web-based Geographic Information Systems tool was created. The following information can be viewed as layers within these interactive maps:

  • ALUCP Compatibility Zones (1993)
  • ALUCP Airport Noise Contours (2020 DRAFT)
  • ALUCP Compatibility Zones (2020 DRAFT)
  • ALUCP Airport Overflight Notification Area (2020 DRAFT)
  • ALUCP Airport Influence Area (2020 DRAFT) 
  • County Code 333 Airport Approach Zone Building Height Restrictions [14 CFR Part 77 surfaces]
