Trigger predicate

When this evaluates true for a parcel, the law's preempted fields take precedence over base zoning.

AND
  • city.governance_class ≠ first_class_city
  • parcel.base_zone_category == res_sf

Preempted fields

3 fields on the base district schema are rewritten when the trigger fires.
