Trigger predicate

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

parcel.in_critical_groundwater_area == True

Preempted fields

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

Research notes

Critical Groundwater Area designation is a **non-regulatory** awareness program — does NOT cap permitted withdrawals or impose by-right development restrictions. Designated areas (per 2024 update) include the Alluvial and Sparta aquifers of eastern Arkansas (Grand Prairie / Mississippi Alluvial Plain), driven by irrigation-volume drawdowns and the unsustainable cone-of-depression in the Sparta aquifer south of I-40. The hard-regulatory companion is the Conservation Reserve Program (federal) and the Arkansas water-use registration system (§15-22-302). Cities in CGAs (Stuttgart, Brinkley, Forrest City, Pine Bluff, Helena-West Helena, Dumas, McGehee) may impose complementary irrigation/landscape standards but cannot rely on §15-22-901 as preempting power on water-intensive uses.
