1. In landscape architecture, the term “functional zoning” primarily
refers to:
A. Arranging plant species according to aesthetic appeal
B. Organizing site areas based on intended activities and uses
C. Dividing a property according to soil types
D. Establishing construction phases for a project
B. Organizing site areas based on intended activities and uses
Functional zoning ensures that each area of a site supports specific
activities, enhancing usability, circulation, and overall design
efficiency.
2. Which soil property most directly affects a plant’s ability to access
water?
A. Texture
B. pH
C. Color
D. Organic content
A. Texture
Soil texture, defined by the proportion of sand, silt, and clay, governs
, water retention and drainage, directly influencing plant water
availability.
3. The primary purpose of a stormwater detention basin in landscape
design is to:
A. Provide recreational amenities
B. Reduce peak runoff and mitigate flooding
C. Improve soil fertility
D. Enhance visual aesthetics
B. Reduce peak runoff and mitigate flooding
Detention basins temporarily store stormwater, releasing it slowly to
minimize downstream flooding and erosion, which is a key
component of sustainable site design.
4. Which native plant characteristic is most critical for successful
establishment in a new landscape?
A. Seed color
B. Drought tolerance
C. Leaf size
D. Flower fragrance
B. Drought tolerance
Plants adapted to the local climate, particularly those with drought
tolerance, are more likely to survive, reduce maintenance, and
require less supplemental irrigation.
5. In site grading, a 2% slope is generally recommended for:
A. Athletic fields
B. Roof terraces
C. Pedestrian walkways
D. Parking lots
C. Pedestrian walkways
A 2% slope provides sufficient drainage for walkways without
creating discomfort or accessibility issues for pedestrians.
6. Which planting technique helps prevent soil erosion on steep slopes?
A. Mulching only
B. Terracing or using retaining structures
C. Drip irrigation
D. Seed broadcasting
, B. Terracing or using retaining structures
Terracing reduces slope length and gradient, stabilizing soil and
allowing vegetation to establish, which effectively controls erosion.
7. The Americans with Disabilities Act (ADA) guidelines for accessible
routes require a maximum slope of:
A. 1:10
B. 1:12
C. 1:15
D. 1:20
B. 1:12
ADA standards specify a maximum slope of 1:12 for ramps to ensure
safe and accessible movement for individuals with mobility
impairments.
8. In sustainable landscape design, a rain garden primarily functions to:
A. Enhance visual appeal
B. Capture and filter runoff before it reaches storm drains
C. Serve as a wildlife sanctuary
D. Increase recreational space
B. Capture and filter runoff before it reaches storm drains
Rain gardens are designed to retain and infiltrate stormwater,
removing pollutants and reducing the volume of water entering
municipal storm systems.
9. The use of permeable pavements is most effective for:
A. Increasing soil pH
B. Reducing urban heat island effect
C. Managing stormwater runoff
D. Enhancing soil compaction
C. Managing stormwater runoff
Permeable pavements allow water to infiltrate the ground rather
than running off impervious surfaces, helping control flooding and
improve water quality.
10. Which principle best describes the “borrowed view” in
landscape design?
A. Using adjacent landscapes to visually extend the site
B. Incorporating water features to reflect sunlight
