Chapter 17

Page 1: Designing for Urban Life

Overview of Urban Growth

  • Human Decisions: Cities grow due to a mix of conscious and unconscious decisions by humans.

  • Geographic Processes: Understanding these processes aids in designing sustainable and livable cities.

Learning Objectives

  • Identify different urban design initiatives and practices.

  • Explain the effects of these initiatives.

Urban Sustainability

  • Challenge: Cities face sustainability issues as they grow and populations shift.

  • Definition: Urban sustainability involves controlling pollution and reducing a city's ecological footprint.

    • Ecological Footprint: Measure of land required to sustain urban resource use.

Livability in Cities

  • Concept: Livability is determined by factors affecting quality of life, including:

    • Built and natural environments

    • Economic prosperity

    • Social stability, equity

    • Access to educational, cultural, and entertainment opportunities

  • People in livable cities have little reason to leave.

Sustainable Design Initiatives

  • Urban planners are implementing various sustainable design strategies, such as:

    • Mixed Land Use: Combines residential and commercial spaces to minimize travel needs and reduce sprawl.

    • Walkability: Safe, convenient environments for pedestrians and cyclists.

    • Transportation-Oriented Development: Communities that focus on public transit accessibility.

    • Smart Growth Initiatives: Includes New Urbanism, greenbelts, and slow-growth strategies.

Urban Sprawl and Its Impacts

  • Issues:

    • Environmental degradation

    • Loss of rural land

    • Increased pollution from reliance on cars

  • Mixed-use Development (MUD):

    • A planned space incorporating various uses (residential, commercial, etc.) designed to increase density and reduce transport needs.

    • Examples: Vertical mixed-use buildings, neighborhood blocks of different types of housing, businesses, and recreational areas.

Walkability Characteristics

  • Influences on walkability include:

    • Availability of multi-use paths and bike-friendly infrastructure.

    • Access to facilities within walking distance;

  • Cities improving walkability through revitalization and redevelopment efforts.

Transportation and Sustainability

  • Transportation Goals: Improve access to public transit to reduce car dependency, save fossil fuels, and lower pollution levels.

    • Examples of effective transportation systems:

      • Arlington County, Virginia: Created transit-friendly neighborhoods, achieving 36 million square feet of office space and over 47,000 housing units.

  • Effectiveness of Strategies: Integrated transport systems reduce environmental impacts and enhance urban livability.


Page 2: Smart-Growth Policies

Overview of Smart-Growth Initiatives

  • Purpose: Control urban sprawl and enhance livability through policies promoting sustainable development.

  • Example: Arlington County uses incentives for mixed-use developments.

Zoning as a Smart-Growth Tool

  • Zoning Laws: Regulate land use, promoting higher density and mixed-use developments.

    • Types: Mixed-use zoning versus traditional zoning that segregates uses by type.

  • New Urbanism: A movement advocating for reduced urban sprawl, preserving nature, and creating inclusive community spaces.

Successful Case Studies

  • Rosslyn-Ballston Corridor: An example of New Urbanist principles in action, focusing on pedestrian-oriented development.

  • Curitiba, Brazil: Known for sustainable urban planning since the 1970s, including innovative public transit solutions and preserved green spaces.


Page 3: Commute Times and Urban Issues

Average Commute Trends

  • 1980 vs. 2018 Commute Times:

    • Average increased from 21.9 minutes to 27.1 minutes.

    • Additional time correlates with increased annual commuting hours (22.6 hours per year).

Worst Commute Areas in 2019

  • Notable cities with long average commute times, including Naperville, IL, and New York City.

Commute Impact on Well-Being

  • Study findings from the UK indicate longer commutes negatively affect happiness levels.

  • Commuting Demographics: Significant amounts of time spent commuting can lead to lower quality of life.

Urban Planning Response

  • Solutions: Integrating smart-growth strategies to enhance urban living by addressing commute challenges.

  • Curitiba's Initiatives: Early adopter of sustainable practices, including improved public transit systems and engagement in environmental regulation.


Page 4: Growth Management and Urban Challenges

Growth Management Policies

  • Definition: Strategies used to ensure urban development does not overwhelm existing infrastructure.

  • Zoning Regulations: Large-lot zoning to limit sprawl and promote high-priced housing, impacting affordability.

  • Benefits of Proper Management: Protects farmland and encourages higher-density communities to minimize environmental impact.

Housing Diversity and Accessibility

  • Goals: Promoting mixed-income neighborhoods through diverse housing options to meet urban needs.

  • Examples: Tucson's transformation of public housing into mixed-income units.


Page 5: Environmental and Social Factors in Urban Design

Urban Greenbelts

  • Definition: Rings of parkland or agricultural land around cities to limit urban spread and promote ecological health.

  • Social Benefits: Provides access to nature for urban residents, enhancing quality of life.

Urban Planning Challenges

  • Inclusivity in Planning: Citizen involvement is crucial in designing spaces that effectively meet community needs.

  • Greenbelt Case Studies: The historical establishment of greenbelts, such as London's Green Belt, illustrates the need for effective land use regulation.


Page 6: Social Dynamics in Urban Design

Smart Growth Social Impacts

  • Benefits: Promotes diverse communities and social interactions across demographic lines.

  • Critiques: New developments may lead to displacement of lower-income residents and lack of true diversity in gentrifying neighborhoods.

Case Studies for Analysis

  • Baxter Village: Examples of socioeconomic segregation despite well-intended design.

  • Providence, Rhode Island: Urban reimagining focused on inclusivity but has not achieved expected economic diversity.


Page 7: Urban Growth Theory and Legal Aspects

Legal Aspects of Urban Growth

  • Rental Market Challenges: Exclusionary practices and gentrification implications for low-income demographics.

  • Land Tenure Issues: Women often face increased barriers when claiming property rights, exacerbating socioeconomic challenges.

Urban Planning Strategies

  • Inclusionary Zoning: Laws designed to promote affordable housing in new developments, impacting overall housing markets.

  • Challenges of Implementation: Debates over costs and market pricing complexities tied to inclusionary practices.

Historical Context

  • Redlining and Blockbusting: Historical practices shaping current urban landscapes and affecting populations' access to housing.


Page 8: Urban Sustainability Challenges

Environmental Justice and Urban Farming

  • Urban farming initiatives provide fresh food alternatives and combat environmental inequalities.

  • Grassroots organizations champion environmental initiatives to improve air quality.

Urban Renewal and Gentrification

  • Urban Renewal Projects: Historical efforts leading to reinvestment but causing displacement.

  • Gentrification benefits vs. drawbacks: Improved neighborhoods vs. loss of low-income housing availability.


Page 9: Global Urbanization and Challenges

Urbanization Trends

  • Rapid growth in periphery cities, such as Delhi and Jakarta, shows significant internal migration driven by economic conditions.

  • Squatter Settlements: As populations rise, these areas reveal the urgent need for better housing solutions.


Page 10: Comprehensive Planning Solutions

Sustainable Urban Solutions

  • Regional Planning: Involves cooperative government efforts to address sustainability at a broader scale.

  • Brownfield Remediation: Revitalizing contaminated sites to enhance urban sustainability and decrease abandonment.


Page 11: Future Urban Innovations

Designing for Future Cities

  • Emphasis on renewable energy buildings that maximize environmental benefits and community engagement.

  • Principles of Livability: Future cities prioritize safety, green spaces, and accessibility.
