In urban restoration contexts, which option best represents a common restoration approach?

• A. Upgrading the electrical grid.
• B. Replacing vegetation with concrete.
• C. Expanding a highway.
• D. Re-vegetation with native species on a new underground parking garage.

Answer: (D)

Restoration in urban contexts is about bringing back ecological functions and biodiversity within the built environment, even when development continues. Re-vegetation with native species on a new underground parking garage embodies that idea by restoring plant life and ecosystem processes in a space that would otherwise be covered by impervious surfaces. Native species are adapted to local conditions, support local wildlife, help with stormwater infiltration, reduce heat, and improve aesthetics, all of which contribute to a more resilient urban ecosystem.

In contrast, upgrading the electrical grid focuses on infrastructure reliability, not ecological restoration. Replacing vegetation with concrete eliminates habitat and biodiversity, which runs counter to restoration goals. Expanding a highway increases imperviousness and fragmentation, further harming ecosystems rather than restoring them.
