Compatibility Zone and AIA Maps

For each airport, satellite photos are overlaid with zone boundaries and the AIA. Parcel maps are included to show zone and AIA boundaries relative to parcel boundaries.

Compatibility Zones and the AIA

For your reference, here is the Compatibility Zone Matrix from the adopted ALUCP and supporting material. These tables appear in Section 7 of Chapter 2 of the draft.

  • Compatibility Matrix
  • Compatibility Zone Safety Factors

  • Generalized zone diagrams — canonical compatibility zone diagrams for both the two-sided traffic pattern and the one-sided traffic pattern

  • Airport Influence Area (AIA) — An AIA is defined around each airport to specify the area where state-mandated real estate disclosures must be provided to property buyers indicating that an airport is nearby. (See Civil Code 1102.6a, and Business and Professional Code 11010.) Also, any structures over 150' above ground in the AIA must be reviewed by the ALUC. See the section below for AIA maps for each airport.

 

Hayfork

The Hayfork Airport compatibility zones and AIA were reviewed by the ALUC at the March 26 workshop. The standard zones were modified to follow parcel lines in Zones B1, B2 and C. Also, Hayfork's zones reflect the one-sided traffic pattern.

 

Hyampom

The Hyampom Airport compatibility zones and AIA were reviewed by the ALUC at the April 23 workshop. The standard zones were modified to reflect the one-sided traffic pattern and displaced threshold.

 

Ruth

The Ruth Airport compatibility zones and AIA were reviewed by the ALUC at the March 26 workshop. The standard AIA was modified to follow section lines off the north end of the airport to reflect the common departures down-river.

 

Trinity Center

The Trinity Center Airport compatibility zones and AIA were reviewed by the ALUC at the April 23 workshop. The standard zones were modified to reflect the one-sided traffic pattern and displaced thresholds. Zone C on the west side was modified to follow the western edge of Lakeview Drive. At the July 9 ALUC meeting, Zone B1 was updated to exclude all R-1 parcels on the southwest side of the runway.

 

Weaverville

The Weaverville Airport compatibility zones and the AIA were reviewed by the ALUC at the March 26 workshop. Zones A, B1, B2 and D were modified to reflect the one-way runway and the concentration of traffic over downtown Weaverville.
