What is a direct objective of vulnerability mapping in urban planning?

• A. Identifying parts of a neighborhood at risk from sea-level rise or urban heat.
• B. Calculating street intersection density.
• C. Modeling groundwater flow.
• D. Designing athletic facilities.

Answer: (A)

Vulnerability mapping in urban planning focuses on locating where a city is most exposed to hazards and where people, assets, and services have limited ability to cope. By layering data on hazards (like sea-level rise, floods, or heat) with information about neighborhoods, populations, and critical infrastructure, planners identify hotspots where vulnerability is highest. This direct aim guides where to invest in protections, such as flood defenses, elevated roads, cooling and green infrastructure, and targeted outreach or services for at-risk communities.

Other options involve different kinds of analysis. Calculating street intersection density helps with understanding walkability and traffic patterns, not potential harm from hazards. Modeling groundwater flow deals with subsurface water behavior, which is a hydrology concern. Designing athletic facilities centers on recreation and sport infrastructure. None of these are about pinpointing where vulnerability to environmental hazards is greatest, which is why identifying at-risk neighborhoods is the best fit.
