Urban infill involves the development of vacant or underutilized parcels within existing urban areas. This practice contrasts with urban sprawl, promoting more efficient use of land and infrastructure in urban regions. The primary aim is to rejuvenate and densify communities, making cities more livable, sustainable, and economically viable.
Historical Context
Urban infill has gained prominence particularly in the 21st century as a response to the adverse effects of urban sprawl, such as environmental degradation, increased commuting times, and strained infrastructure. Historically, the practice dates back to times when urban centers evolved organically, utilizing every available space to meet population demands.
Types/Categories of Urban Infill
- Residential Infill: Construction of new housing units within an established residential area.
- Commercial Infill: Development of businesses and commercial buildings in previously underutilized urban locations.
- Mixed-Use Infill: Combination of residential, commercial, and recreational uses in a single development.
- Industrial Infill: Repurposing urban land for manufacturing or industrial purposes.
Key Events
- 1940s-1960s: Post-WWII suburbanization in the United States leads to urban decline.
- 1970s-1980s: Revival of interest in urban centers spurred by economic and social factors.
- 1990s: Introduction of policies promoting smart growth and sustainable urban development.
- 2000s-Present: Increasing focus on sustainability, climate change, and the efficient use of urban land.

Importance of Urban Infill
- Environmental Sustainability: Reduces the need for new infrastructure, minimizes land consumption, and helps preserve natural habitats.
- Economic Efficiency: Utilizes existing utilities and services, reducing the cost of extending infrastructure to new developments.
- Community Vitality: Revitalizes neighborhoods, reduces crime rates, and encourages vibrant, diverse communities.
- Transportation Benefits: Promotes public transit, walking, and biking, reducing traffic congestion and greenhouse gas emissions.
Applicability and Examples
- Urban Infill in Detroit: Revitalization of vacant lots into community gardens, new housing, and commercial spaces.
- Brownfield Redevelopment in New York City: Conversion of former industrial sites to mixed-use developments.
- Infill Housing in Portland, Oregon: Encouragement of ADUs (Accessory Dwelling Units) and infill housing to increase density and affordability.
Considerations
- Community Impact: Ensuring development respects existing community character and needs.
- Infrastructure Capacity: Assessing if current infrastructure can support increased density.
- Environmental Impact: Mitigating any potential negative environmental effects through sustainable practices.
- Zoning Laws: Adapting or updating zoning regulations to facilitate urban infill projects.
Related Terms with Definitions
- Smart Growth: Planning and building principles that aim to create sustainable and livable communities.
- Brownfield: Previously developed land, often industrial, that may be contaminated but has potential for redevelopment.
- Greenfield: Undeveloped land, typically on the outskirts of urban areas, considered for new developments.
Comparisons
- Urban Infill vs. Urban Sprawl: Infill focuses on reusing existing spaces within urban areas, while sprawl extends development to peripheral areas, consuming more land and resources.
