Preempted fields
3 fields on the base district schema are rewritten when the trigger fires.
| Field | Op | Value | Note |
|---|---|---|---|
base_districts[*].agricultural_nuisance_protection_applies | override | True | §46-45-30: agricultural operations existing for 1+ year cannot be deemed a public or private nuisance based on changed conditions in surrounding non-agricultural land use ('coming to the nuisance' doctrine). |
base_districts[*].local_ag_operation_zoning_restrictions | cap_at | non_targeting_general_applicability | Local governments may not adopt ordinances that retroactively render an existing agricultural operation unlawful or that single out agricultural operations for stricter regulation. |
base_districts[*].use_value_assessment_zoning_interaction | add | agricultural_use_value_8_pct_assessment_ratio | S.C. Const. Art. X §1(B) and §12-43-220(d) authorize current-use 'agricultural use value' assessment for qualifying ag/timber tracts — rezoning or conversion triggers 5-year rollback taxes per §12-43-220(d)(4). |

Research notes
SC's right-to-farm protection is statutory (Title 46 Chapter 45) rather than constitutional. The use-value assessment program (§12-43-220(d)) is the analogue to NC Present Use Value and GA CUVA — owners receive lower current-use tax valuation in exchange for keeping land in qualifying agricultural/timber use. Rezoning or conversion triggers 5-year rollback taxes. Strongest application in the row-crop and timber counties (Allendale, Bamberg, Calhoun, Clarendon, Colleton, Hampton, Marion, Marlboro, Williamsburg) and at the rural fringe of metro Columbia / Greenville / Charleston. ACE Basin (Ashepoo-Combahee-Edisto rural focus area) protection rests on this statute plus Heritage Trust easements — not a separate regulatory overlay.
