A shallow, vegetated depression that collects and infiltrates stormwater runoff

Answer

A garden that exclusively uses rainwater for drip irrigation

Answer

A formal garden feature incorporating decorative fountains

Answer

An elevated planting bed used for food production

Question 2

What is the primary benefit of permeable pavement in sustainable landscape design?

Accepted Answer

Allowing stormwater to infiltrate through the surface into the ground below

Answer

Lower initial installation cost compared to traditional asphalt

Answer

Higher load-bearing capacity for heavy vehicle traffic

Answer

Reducing the need for vegetation elsewhere on the site

Question 3

Urban tree canopy contributes to sustainable design primarily by:

Accepted Answer

Providing shade, reducing heat island effect, intercepting rainfall, and improving air quality

Answer

Increasing impervious surface area around tree wells

Answer

Blocking views to increase site privacy for residents

Answer

Reducing biodiversity by shading out ground-level vegetation

Answer

Connecting site irrigation systems to reclaimed water supplies

Answer

Linking surface stormwater channels to natural waterways

Question 6

What is the purpose of a bioretention cell in green infrastructure?

Accepted Answer

To collect and treat stormwater runoff through engineered soil media, plants, and microorganisms

Answer

To drain water away from a site as quickly as possible

Answer

To provide recreational swimming areas in urban parks

Answer

To increase soil compaction for structural support

Question 7
