Which of the following does LEED promote by encouraging compact development?
- A. Urban sprawl
- B. Walkability
- C. Development of new infrastructure
- D. Historic preservation
Answer: B
Explanation:
One of the things that LEED promotes by encouraging compact development is walkability. Compact development is a form of urban planning that aims to reduce sprawl and make more efficient use of land and resources by increasing density, diversity, and connectivity of land uses5. Compact development can enhance walkability by creating mixed-use neighborhoods that provide a variety of destinations within walking distance, such as shops, services, workplaces, schools, parks, and transit stops. Walkability can offer multiple benefits for the environment, health, economy, and social equity. For example, walkability can reduce greenhouse gas emissions and air pollution by replacing car trips with walking or transit; improve physical and mental health by increasing physical activity and reducing stress; support local businesses and generate tax revenues by increasing foot traffic and property values; and foster social cohesion and civic engagement by creating vibrant public spaces and enhancing accessibility for all6.
