1. Which of the following best defines the primary purpose of a
landscape architect’s site analysis in the initial project phase?
A. To create construction documents for contractors
B. To determine planting schedules and irrigation needs
C. To evaluate existing site conditions and constraints to inform
design decisions
D. To select materials and finishes for aesthetic appeal
Rationale: The primary purpose of a site analysis is to understand existing
conditions, constraints, and opportunities, which guides the conceptual
design and overall planning of the landscape project.
2. In stormwater management, what is the main function of a
bioretention cell?
A. To store water for irrigation permanently
B. To convey runoff to the nearest storm drain
C. To treat and infiltrate stormwater through vegetation and soil
, media
D. To prevent erosion by stabilizing slopes only
Rationale: Bioretention cells are designed to capture, treat, and infiltrate
stormwater using a combination of soil media, vegetation, and sometimes
underdrain systems, reducing pollutant loads and peak flows.
3. When designing an accessible route according to ADA standards, what
is the maximum slope allowed for a ramp without requiring handrails?
A. 1:8
B. 1:10
C. 1:12
D. 1:20
Rationale: ADA standards specify a maximum slope of 1:12 for ramps;
slopes steeper than this typically require handrails and additional safety
measures to ensure accessibility.
4. Which principle is most important when integrating a landscape
design with its surrounding ecological context?
A. Maximizing hardscape area for human activity
B. Using exotic plant species to create a distinct appearance
C. Preserving and enhancing native habitats and ecological functions
D. Focusing solely on aesthetic composition without regard to ecology
Rationale: Ecologically responsive landscape design prioritizes native
habitats, biodiversity, and ecosystem functions, ensuring that the project
supports long-term environmental sustainability.
5. In landscape grading, what is the primary purpose of a swale?
A. To provide pedestrian circulation
B. To serve as a decorative water feature
C. To convey stormwater while promoting infiltration and reducing
erosion
D. To act as a boundary marker between property lines
,Rationale: Swales are shallow, vegetated channels designed to manage
stormwater runoff by conveying it while promoting infiltration and slowing
flow to prevent erosion.
6. Which planting strategy is most effective for reducing the urban heat
island effect?
A. Concentrating trees only along streets
B. Using turfgrass over the entire site
C. Incorporating canopy trees, green roofs, and reflective surfaces
strategically
D. Relying solely on shrubs and groundcovers
Rationale: Reducing urban heat island effect requires a combination of
shading from canopy trees, green roofs, and reflective surfaces to lower
ambient temperatures and improve microclimates.
7. When specifying paving materials for a high-traffic public plaza, which
factor is least critical?
A. Durability and load-bearing capacity
B. Slip resistance and safety
C. Color matching with interior furniture
D. Maintenance and longevity
Rationale: While aesthetics are important, color matching with interior
furniture is generally less critical than durability, safety, and maintenance
considerations in high-traffic landscape areas.
8. What is the key design intent of a “circulation hierarchy” in landscape
architecture?
A. To eliminate all vehicular traffic from the site
B. To provide random paths for aesthetic interest
C. To organize primary, secondary, and tertiary paths for efficient
movement and safety
D. To maximize the number of formal entry points
, Rationale: Circulation hierarchy organizes pedestrian and vehicular routes
according to use and importance, improving accessibility, safety, and
overall site functionality.
9. In selecting plants for a riparian restoration project, which criterion is
most important?
A. Growth rate and ornamental flowers
B. Shade tolerance for nearby structures
C. Native species adapted to floodplain conditions
D. Compatibility with artificial irrigation systems
Rationale: Riparian restoration prioritizes native species that are adapted
to periodic flooding and soil conditions to stabilize banks, enhance habitat,
and maintain ecosystem integrity.
10. Which method is most effective in reducing wind erosion on a
large open landscape site?
A. Installing decorative benches along wind corridors
B. Planting windbreaks such as rows of trees or shrubs
C. Using only turfgrass to cover open soil
D. Applying mulch sporadically in random locations
Rationale: Windbreaks reduce wind velocity, protect soil from erosion, and
can improve microclimatic conditions, making them a primary strategy for
erosion control on exposed sites.
11. Which type of plan is primarily concerned with illustrating the
vertical relationships and grading changes across a site?
A. Planting plan
B. Lighting plan
C. Topographic or grading plan
D. Irrigation plan
Rationale: Grading or topographic plans show contour lines, elevations,
and slopes, providing critical information for drainage, construction, and
site design decisions.
