Keyline® in the AR Sandbox #7: The City Forest

The video explores the application of PA Yeomans' Key Line Design to urban planning, focusing on water and soil management. It introduces a city design model based on water flow and solar gain, dividing the city into Uptown, Midtown, and Low Town. The design emphasizes infrastructure for water management, residential and industrial zoning, and the integration of a City Forest for ecological balance.

What is the primary focus of Key Line Design in urban environments?

• Building architecture

• Traffic management

• Water and soil management

• Energy efficiency

In the city design model, what is the significance of the main ridge or spine?

• It is the location for industrial zones.

• It encloses the primary land unit for city design.

• It is the highest point for solar panels.

• It serves as the main transportation route.

How are lakes and roads integrated into the city's infrastructure?

• Lakes are used for recreational purposes only.

• Roads are elevated to prevent flooding.

• Roads are built to avoid water flow.

• Lakes and roads are designed to manage water flow and drainage.

How does the city design ensure efficient water flow during heavy storms?

• By building underground tunnels

• By elevating all roads

• By using a series of lakes and feeder roads

• By constructing large dams

What is the purpose of tree-lined roads in the residential zones?

• To provide shade and wind protection

• To increase property values

• To separate commercial and residential areas

• To reduce noise pollution

What is the main benefit of placing taller buildings in the Uptown area?

• To provide better views of the city

• To ensure they don't block solar access for residential areas

• To centralize business and commerce

• To create a skyline for the city

Why is the valley form preferred for handling stormwater overflow?

• Valleys are closer to water treatment facilities.

• Valleys are naturally more beautiful.

• Valleys can handle massive inundation better than ridges.

• It is easier to construct drainage systems in valleys.

What role does the City Forest play in urban water management?

• It is a location for commercial development.

• It processes wastewater and manages excess runoff.

• It serves as a recreational area only.

• It is used for agricultural purposes.

What is the purpose of the water reconstitution zone beyond the city forest?

• To create new recreational parks

• To leave riverfronts wild and receive clean water

• To develop new residential areas

• To build industrial complexes

What is the role of the central valley in the city's wastewater management?

• It is a location for commercial development.

• It is used for recreational activities.

• It concentrates wastewater for treatment.

• It serves as a natural barrier against floods.
