BLArch Bachelor of Landscape Architecture Bachelor of Landscape Architecture 3 — Questions and Answers
Question 1: Which landscape architect is credited with designing New York City's Central Park alongside Calvert Vaux?
- Charles Eliot
- Frederick Law Olmsted Sr. (Correct answer)
- Jens Jensen
- Daniel Burnham
Correct answer: Frederick Law Olmsted Sr.
Frederick Law Olmsted Sr. and Calvert Vaux collaborated on the Greensward Plan, which won the 1858 design competition for Central Park.
Question 2: In planting design, a 'drifts' planting pattern is best described as:
- Single specimens placed at focal points
- Repetitive groups of plants arranged in elongated, irregular masses (Correct answer)
- Alternating rows of contrasting species
- A formal grid of identical shrubs
Correct answer: Repetitive groups of plants arranged in elongated, irregular masses
Drifts are elongated, irregular groupings of the same plant species that create naturalistic, flowing compositions in the landscape.
Question 3: Which concept describes the minimum connected land area needed to sustain a viable wildlife population?
- Edge effect threshold
- Minimum viable habitat patch (Correct answer)
- Carrying capacity corridor
- Biodiversity hotspot index
Correct answer: Minimum viable habitat patch
Minimum viable habitat patch refers to the smallest area that can support self-sustaining populations and is a core principle in landscape ecology and greenway planning.
Question 4: A 'permeable paver' system reduces stormwater runoff primarily by:
- Absorbing rainfall into the paver material itself
- Allowing water to infiltrate through joints or voids into a stone reservoir below (Correct answer)
- Channeling runoff to a central drain faster than traditional paving
- Evaporating moisture through a reflective surface coating
Correct answer: Allowing water to infiltrate through joints or voids into a stone reservoir below
Permeable pavers have open joints or voids filled with aggregate, directing stormwater into a subbase reservoir where it infiltrates into the native soil.
Question 5: The USDA Plant Hardiness Zone Map divides the country based on:
- Average annual rainfall totals
- Average annual extreme minimum temperature (Correct answer)
- Soil pH ranges and fertility
- Frost-free growing days per year
Correct answer: Average annual extreme minimum temperature
The USDA Hardiness Zone Map is based on average annual extreme minimum temperatures, helping designers select plants that can survive winter cold in a given region.
Question 6: In the LEED rating system, which credit category most directly rewards landscape architects for reducing site irrigation water use?
- Sustainable Sites — Heat Island Reduction
- Water Efficiency — Outdoor Water Use Reduction (Correct answer)
- Materials and Resources — Regional Materials
- Innovation — Pilot Credit
Correct answer: Water Efficiency — Outdoor Water Use Reduction
LEED's Water Efficiency category includes an Outdoor Water Use Reduction credit that rewards projects for using drought-tolerant plants, efficient irrigation, or no irrigation.
Question 7: Which of the following is a primary function of a detention basin in stormwater management?
- Permanently retaining water to support aquatic habitat
- Temporarily storing runoff to reduce peak discharge rates (Correct answer)
- Filtering nutrients through constructed wetland vegetation
- Recharging groundwater through infiltration only
Correct answer: Temporarily storing runoff to reduce peak discharge rates
Detention basins temporarily hold stormwater and release it slowly, reducing peak flow rates that would otherwise cause downstream flooding.
