Which practice is an example of urban growth containment through development in already urbanized areas?

• A. Car-centric highway expansion.
• B. Infill development.
• C. Suburbanization without planning.
• D. Urban sprawl into rural areas.

Answer: (B)

Infill development concentrates new growth within the existing urban area by redeveloping vacant lots, underused sites, or empty buildings. This approach makes use of the infrastructure and services already in place—streets, utilities, transit—so development stays compact and within the city’s boundaries. By increasing density inside the urban footprint, it helps keep housing and jobs close to services, reduces the need to expand roads and utilities into rural or undeveloped land, and supports walkability and mixed-use neighborhoods. In this way, growth is contained where it already exists, rather than sprawling outward.

Other practices push growth outward or rely on new road expansion, which tends to encourage more suburban and rural development, increasing commute times and land consumption rather than containing growth within the urban core.
