Discusses Alternative Designs For Development Tha

Chapter 13 discusses alternative designs for development that take into account protection of environmentally sensitive areas, public transportation, walkable, mixed-use neighborhoods, etc. The term "smart growth" is often used to describe this method of planning. Do you have examples of green communities in Los Angeles? What do you think are the biggest health benefits from these compared to traditional development? What factors lie behind the shift of population from rural areas to urban areas? What types of cities and countries are experiencing the fastest urban growth today, and why? Why have so many city dwellers in the United States, Canada, and other nations moved into suburbs? How are some people trying to prevent or slow sprawl? Describe some key elements of “smart growth.” What effects, positive and negative, do urban growth boundaries tend to have?

Urban development has evolved significantly over the past few decades, largely driven by the concept of smart growth, which emphasizes sustainable, environmentally friendly, and community-oriented planning. In Los Angeles, several green communities exemplify these principles, integrating renewable energy, green spaces, efficient public transportation, and walkable neighborhoods. Projects like the Playa Vista community and the Stapleton neighborhood in Denver (though not LA, but comparable in concept) showcase efforts to reduce carbon footprints, promote health, and foster community engagement (Ellis & Macdonald, 2018). Such developments contrast with traditional sprawling suburbs characterized by car dependency, segregated land uses, and lower walkability, which contribute to health issues such as obesity and respiratory problems due to increased pollution from vehicle emissions (Gordon-Larsen et al., 2018).

The shift of population from rural to urban areas is mainly driven by economic opportunities, access to better healthcare and education, and improved amenities in cities. Rapid urban growth is most evident in countries like India, Nigeria, and Brazil, where demographic transition and urbanization rates are high, fueled by rural-to-urban migration and natural population growth (United Nations, 2012). These countries are experiencing fast urbanization due to changing economic structures, population growth, and global migration trends.

In the United States, Canada, and similar nations, suburbanization has largely been driven by the pursuit of affordable housing, perceived safer and better environments for families, and the desire for space and privacy. Advances in transportation technology, especially the development of the automobile, facilitated this shift away from urban cores (Glaeser & Kahn, 2010). However, this migration has contributed to sprawl, with its associated problems—including traffic congestion, loss of agricultural land, and increased greenhouse gas emissions.

Efforts to curb sprawl include developing urban growth boundaries (UGBs), which aim to contain urban expansion within designated limits, encouraging higher-density development inside these zones. Key elements of smart growth include compact building design, diverse housing options, accessible public transit, and preservation of natural and agricultural lands (Bengston et al., 2015). While urban growth boundaries can prevent sprawl, they may also lead to increased housing costs and limited land availability, which can exacerbate affordability issues and push development to areas outside set boundaries, sometimes leading to environmental degradation in those regions (Ewing & Hamidi, 2014).

In conclusion, sustainable urban planning through smart growth principles and policies like urban growth boundaries can help create healthier, more livable, and environmentally sustainable communities. However, balancing development needs, environmental protection, and social equity remains a challenge requiring ongoing policy innovation and community engagement (Neuman & Firey, 2017).
