What is the purpose of scenario planning in planning practice?

• A. To forecast a single future with precision
• B. To enforce zoning by right
• C. To create detailed architectural drawings
• D. To compare multiple potential futures and evaluate policy outcomes under uncertainty

Answer: (D)

Scenario planning in planning practice centers on exploring multiple plausible futures and evaluating how policies perform across those possibilities when the future is uncertain. Rather than predicting a single outcome with precision, planners build several scenarios that vary key drivers—like demographics, economy, climate, and technology—and assess which options remain effective under each. This helps identify strategies that are robust and adaptable, so decisions can be adjusted as events unfold. For example, in planning for climate resilience, you would compare how infrastructure and land-use policies hold up under different levels of sea‑level rise and storm intensity. The other options miss the essence: forecasting a single future with precision ignores uncertainty, enforcing zoning by right is a regulatory action, and creating architectural drawings is a design task, not scenario analysis.
