| Summary≠ | Land value capture analysis measures the increase in land and property values that a public investment — a new transit line, station, park, or rezoning — creates, so that some of that windfall can be recovered to help pay for the investment. Grounded in classical economics and synthesized for transit by Smith and Gihring, it isolates the value uplift attributable to the public action, usually with hedonic price models and quasi-experimental before/after comparisons, and then quantifies how large a capturable surplus exists. The logic is one of fairness and finance: when public spending lifts private land values, recovering part of the gain funds the public good that created it. | Suitability analysis maps how well each parcel of land supports a proposed use — housing, conservation, a highway, a landfill — by combining the relevant physical, ecological and accessibility factors into a single composite score. In the tradition established by Ian McHarg's 1969 Design with Nature, each factor is captured as a map layer, reclassified onto a common suitability scale, and overlaid so that places good on many factors stand out from places that are not. The result is a suitability surface that makes the trade-offs in a land-use decision explicit, transparent and defensible. |
