Research notes
Federal-state-regional hybrid overlay. MAC Part 150 noise contours are the binding map; comp plans in affected cities incorporate noise-zone overlay districts. Litigation history (NOC noise concerns, Richfield/Mendota Heights residential restrictions) makes this a load-bearing overlay for any new housing in the south-metro flight paths. Federal conflict check enabled.
