Question 1

A rain garden is best described as:

Accepted Answer

A shallow, vegetated depression that collects and infiltrates stormwater runoff

Answer

Rain gardens are shallow, planted depressions designed to collect stormwater runoff from impervious surfaces and allow it to slowly infiltrate into the ground over 24–48 hours.

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

Permeable pavement allows stormwater to pass through the surface into underlying aggregate layers and then into the soil, reducing runoff volume and recharging groundwater.

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

Urban tree canopy reduces heat island effects through shading and evapotranspiration, intercepts rainfall to reduce runoff, sequesters carbon, and improves air quality simultaneously.

Question 4

Which stormwater management approach involves capturing and storing rainwater from rooftops for later non-potable reuse?

Accepted Answer

Rainwater harvesting with cisterns

Answer

Rainwater harvesting captures and stores precipitation from rooftops in cisterns or tanks for later use in landscape irrigation or other non-potable applications, reducing demand on municipal water supplies.

Question 5

In sustainable landscape design, 'ecological connectivity' refers to:

Accepted Answer

Creating linked habitat corridors that allow wildlife movement through fragmented landscapes

Answer

Ecological connectivity involves designing linked habitat corridors and green spaces that allow wildlife to move through otherwise fragmented urban or suburban landscapes.
