Preempted fields
3 fields on the base district schema are rewritten when the trigger fires.
| Field | Op | Value | Note |
|---|---|---|---|
redevelopment.urban_renewal_area_designation | require | slum_blight_or_economic_development_findings | A city/county may establish an urban renewal area by ordinance for slum/blight clearance OR economic development; designation must fit the unit's general plan for development. |
redevelopment.tif_allocation | permit | section_403_19_incremental_revenue | Iowa Code §403.19 authorizes municipalities to collect and expend incremental property tax revenues to finance urban renewal project costs. Base tax value continues to flow to schools, counties, and other taxing bodies; the increment funds project improvements. |
redevelopment.annual_tif_certification | require | annual_certification_to_dom_and_dept_of_revenue | Cities/counties must annually certify outstanding TIF indebtedness to the County Auditor and file the urban-renewal annual report (UR-1 / UR-2) with the Iowa Department of Management; TIF revenues capped at certified indebtedness. |

Research notes
State framework overlay — not a direct zoning preemption. Captured so city profiles with `has_urban_renewal_area=true` and parcels in `in_urban_renewal_area=true` are flagged for downstream tax/financial underwriting. TIF was added to Ch. 403 in 1969 via §403.19. Iowa TIF is broad relative to peer states (slum/blight OR economic-development purposes), and most growth-corridor cities have at least one active urban-renewal area.
