governance.consolidated_city_county_executiverequireindianapolis_mayor_as_marion_county_executiveUnder Unigov (IC 36-3), the Mayor of Indianapolis serves as the executive of Marion County for unified governance; the City-County Council is the unified legislative body.
zoning_ordinance.unified_zoning_authorityrequiremetropolitan_development_commission_under_IC_36_7_4Zoning across Marion County is administered by the Metropolitan Development Commission (MDC) under IC 36-7-4 — Marion is the only county in Indiana with a unified Metropolitan Plan Commission jurisdiction overriding township and excluded-city plan-commission boundaries. The four excluded cities — Beech Grove, Lawrence, Southport, and Speedway — retain their own zoning authority and are NOT subject to MDC zoning jurisdiction.
zoning_ordinance.indianapolis_marion_county_code_chapter_743requireconsolidated_zoning_ordinanceThe substantive zoning ordinance is the Consolidated Zoning and Subdivision Ordinance (Indianapolis-Marion County Code, Chapter 743 et seq.), adopted by the MDC and approved by the City-County Council — this is the operational layer that downstream TOD, mixed-use, and transit-overlay rules (e.g., Indianapolis Cultural Trail and IndyGo Red Line BRT TOD) plug into.

Research notes

Governance-framework overlay distinct from the substantive redevelopment chapter (IN_36_7_15_1_MARION_REDEVELOPMENT) and the general zoning enabling act (IN_36_7_4_ZONING_ENABLING). The four 'excluded cities' (Beech Grove, Lawrence, Southport, Speedway) and four 'included towns' (Cumberland, Meridian Hills, Rocky Ripple, Spring Hill — among others) interact with the Unigov framework in idiosyncratic ways; city profiles that fall in those exclusions should mark `is_in_marion_county_unigov` accordingly so this overlay's trigger fires correctly. Note: the brief asked for 'Indianapolis-Marion Consolidated City (Unigov) overlays' — this overlay anchors the governance framework; the substantive zoning content lives in Chapter 743 of the Indianapolis-Marion County Code (local layer) and in IC 36-7-15.1 (state redevelopment layer).
