Preempted fields
3 fields on the base district schema are rewritten when the trigger fires.
| Field | Op | Value | Note |
|---|---|---|---|
base_districts[*].max_height_ft | cap_at | faa_part_77_or_aicuz_imaginary_surface | Federal FAA Part 77 (14 CFR Part 77) imaginary surfaces and DoD AICUZ (DoDI 4165.57) noise/safety zones apply at Redstone Arsenal (Cairns), Maxwell AFB / Gunter Annex (Montgomery), Fort Novosel / Cairns AAF (Dale County), Anniston Army Depot (Calhoun). |
base_districts[*].allowed_uses | remove | noise_sensitive_uses_in_aicuz_high_noise_zones | AICUZ Zone 2 (65-75 dB DNL) and Zone 3 (≥75 dB DNL) recommend exclusion of residential, schools, hospitals, churches; APZ-I/II have additional density-floor restrictions. |
zoning_decision_procedure.requires_jlus_compatibility_review_advisory | override | True | Redstone Arsenal JLUS (sponsored by City of Huntsville with City of Madison, Town of Triana, Madison/Marshall/Morgan counties) provides 25-factor compatibility playbook including airspace, frequency spectrum, land use, noise, and safety zones. Advisory — JLUS is not a regulatory document; recommendations are adopted into local code only by separate ordinance. |

Research notes
Federal-overlay conflict check on. Major AL installations: Redstone Arsenal (Huntsville/Madison/Triana) including the NASA Marshall Space Flight Center co-located on the Arsenal; Maxwell AFB / Gunter Annex (Montgomery); Fort Novosel / Cairns AAF (Dale County); Anniston Army Depot (Calhoun); Coast Guard Aviation Training Center (Mobile/Brookley). JLUS compatibility recommendations require separate local-code adoption (the JLUS itself is non-regulatory). Tuskegee Airmen NHS (Moton Field, Macon County) is a National Park Service unit — buffer is curatorial, not regulatory, and tracked separately if a city has adopted a viewshed overlay.
