What is a rain garden in sustainable landscape design?
Answer: A shallow depression planted with water-tolerant plants to capture and filter stormwater runoff
A rain garden is a planted depression that captures roof or pavement runoff, allowing it to infiltrate into the soil over 24 to 48 hours while plants filter pollutants.
What does LEED stand for and how does it relate to landscape design?
Answer: Leadership in Energy and Environmental Design — a green building certification that includes site and landscape criteria
LEED is the US Green Building Council's green building rating system; it includes significant landscape and site credits for water efficiency, habitat, and heat island reduction.
What is the urban heat island effect and how can landscape design mitigate it?
Answer: Cities are hotter than surrounding rural areas; mitigated by trees and reflective surfaces
The urban heat island effect occurs when built surfaces absorb and radiate heat; strategic tree planting and cool paving materials reduce ambient temperatures significantly.
What is a bioswale designed to do in a sustainable landscape?
Answer: Slow, filter, and infiltrate stormwater runoff through vegetation and engineered soil
A bioswale is a vegetated channel engineered to slow stormwater flow, filter pollutants through the root zone, and promote groundwater recharge.
What is a pollinator garden designed to provide?
Answer: Food and habitat for bees, butterflies, and other pollinating insects
Pollinator gardens feature diverse, flowering native and non-invasive plants that provide nectar, pollen, and nesting habitat for bees, butterflies, and other beneficial insects.
What percentage of a landscape's water budget can typically be saved by replacing cool-season turf with drought-tolerant plants and mulch?
Answer: Up to 50 to 75 percent water savings
Replacing irrigated cool-season turf with drought-tolerant plants and mulch can reduce landscape water use by 50 to 75 percent or more, depending on climate and plant choices.
