Trigger predicate
When this evaluates true for a parcel, the law's preempted fields take precedence over base zoning.
OR
project.height_agl_ft≥200- AND
project.distance_to_public_use_airport_nm<5project.height_agl_ft≥0
Preempted fields
3 fields on the base district schema are rewritten when the trigger fires.
| Field | Op | Value | Note |
|---|---|---|---|
review_type | require | INDOT_Aeronautics_tall_structures_permit | Structures >200 ft AGL require INDOT Aeronautics permit. Applicants within 5 nautical miles of a public-use airport must notice the airport owner regardless of county lines. |
base_districts[*].max_height_ft | cap_at | 500 | Permit prohibited for any proposed structure >500 ft AGL statewide, OR >200 ft AGL (or above established airport elevation, whichever is higher) within 3 NM of a public-use airport reference point. |
review_type | accept | FAA_Determination_of_No_Hazard_substitutes_for_state_permit | An FAA Determination of No Hazard to Air Navigation submitted with the application IS the state permit; INDOT does not issue a separate permit. |

Research notes
Federal conflict check flagged because the state permit defers to FAA Part 77 imaginary surfaces and the FAA Determination of No Hazard substitutes for the state permit. Cities cannot grant zoning entitlements that would exceed the state height ceilings in airport-influence areas; this overlay is a state-level airspace ceiling that floors over local zoning in airport-proximate parcels.
