1. Which principle of design refers to the visual stability of
elements within a landscape?
A. Rhythm
B. Balance
C. Contrast
D. Scale
Rationale: Balance creates visual stability by distributing visual
weight throughout a composition.
Correct Answer: B. Balance
2. What is the primary purpose of a site inventory?
A. Develop construction documents
B. Identify existing site conditions and resources
C. Select construction contractors
D. Establish project fees
Rationale: A site inventory documents existing physical,
biological, and cultural conditions before design begins.
Correct Answer: B. Identify existing site conditions and
resources
,3. Which soil characteristic most directly affects water
infiltration?
A. Texture
B. Color
C. Organic odor
D. Mineral age
Rationale: Soil texture, particularly the proportions of sand, silt,
and clay, strongly influences infiltration and drainage.
Correct Answer: A. Texture
4. Which contour pattern indicates a relatively flat area?
A. Widely spaced contour lines
B. Closely spaced contour lines
C. Concentric circles
D. Crossing contour lines
Rationale: Widely spaced contours indicate gradual changes in
elevation and therefore flatter terrain.
Correct Answer: A. Widely spaced contour lines
5. What does a topographic survey primarily document?
A. Property ownership
B. Existing elevations and physical features
C. Construction costs
D. Plant warranties
Rationale: Topographic surveys establish elevations, contours,
and significant existing site features.
Correct Answer: B. Existing elevations and physical features
,6. Which condition generally produces the fastest surface
runoff?
A. Dense vegetation
B. Permeable soil
C. Impervious pavement
D. Mulched planting beds
Rationale: Impervious surfaces prevent infiltration and increase
the amount of water flowing across the surface.
Correct Answer: C. Impervious pavement
7. What is the main purpose of a bioswale?
A. Increase vehicular speed
B. Manage and filter stormwater runoff
C. Eliminate all site grading
D. Provide structural support
Rationale: Bioswales are vegetated drainage features that slow,
convey, infiltrate, and filter stormwater.
Correct Answer: B. Manage and filter stormwater runoff
8. Which orientation generally provides the greatest solar
exposure in the Northern Hemisphere?
A. North-facing
B. South-facing
C. East-facing
D. West-facing
, Rationale: South-facing areas generally receive substantial
annual solar exposure in the Northern Hemisphere.
Correct Answer: B. South-facing
9. Which drawing typically shows property boundaries and
major site features?
A. Site plan
B. Detail drawing
C. Door schedule
D. Finish schedule
Rationale: A site plan establishes the relationship of buildings,
property boundaries, circulation, landscape elements, and
other site features.
Correct Answer: A. Site plan
10. What is the primary function of a grading plan?
A. Specify plant species only
B. Establish proposed site elevations and drainage patterns
C. Determine property ownership
D. Identify architectural finishes
Rationale: A grading plan establishes proposed elevations,
slopes, drainage, and relationships among site features.
Correct Answer: B. Establish proposed site elevations and
drainage patterns
11. A slope of 2% means the elevation changes how much
over a horizontal distance of 100 feet?
A. 0.2 feet
