Final answer:
The design principles of smart growth include promoting traditional nuclear families, determining development locations in advance, and encouraging walking and biking.
Step-by-step explanation:
The design principles of smart growth include promoting traditional nuclear families by building single-family homes, determining in advance where development will take place, and encouraging walking and biking.
These principles aim to create sustainable and livable communities that reduce sprawl, preserve green spaces, and provide accessibility to amenities. For example, by building single-family homes, smart growth promotes family-friendly neighborhoods that cater to the needs of nuclear families.
Additionally, determining where development will take place helps prevent haphazard urban sprawl, while encouraging walking and biking reduces reliance on cars and promotes healthier lifestyles.
