Efficient Land Use Patterns

traditional neighborhood design
Town Center
  • 5-minute walk to most everyday activities
  • Street network forms a continuous web with high inter-connectivity
  • Small, pedestrian-friendly streets
  • Mixed uses and architectural styles throughout
  • Civic and community sites: “identity”
Traditional Neighborhood Design

Community Planning

  • Community Visioning Creates Focus

Air Quality/Greenhouse Gas Reduction

  • Provide Clear Data

Assess traffic patterns, energy usage, common practices

Review local ordinances relating to air quality

  • Establish objectives
      • Reduce vehicular traffic
      • Reduce greenhouse gases
      • Promote green building
      • Promote green rehabilitation for residences and businesses

Indoor Air Quality

  • On average, Americans spend 90% of their time indoors, yet the air inside buildings can be 5-10 times more polluted than outdoor air, according to the U.S. Environmental Protection Agency.
  • Most common pollutants are:
    • Radon
    • Combustion products
    • Molds, pet dander, pollen
    • VOCs
    • Lead dust and asbestos
