Source reconciliation & methodology

The dtic’s 817 ha proposed designation [S2] and Sedibeng’s reported 3,080 ha land programme [S3] are not treated as interchangeable. Gazette 54251 [S8] lists five parcels summing to 3,080 ha; reconciliation is outstanding.

Heidelberg Airport-linked planning, the Vaal Aerotropolis LSDF and Vereeniging Aerodrome rehabilitation are shown as three separate initiatives.

Geography: Municipal boundaries from geoBoundaries ADM3 (simplified). Town locations are real coordinates. Initiative, parcel and opportunity markers are approximate; conceptual areas are dashed circles and corridors are schematic — no cadastral polygons are invented.

Financials: Opportunity capex, revenue, capital stacks, readiness and returns are synthetic. Scenario engine: annual cash flows, NPV, bisection IRR, annuity debt service, DSCR and ±10% sensitivities, recalculated server-side.

Imagery: Concept visuals are AI-generated illustrations, not official renders.
