1. A site has a 6% existing slope toward a proposed building pad. The designer
wants to minimize cut and fill while maintaining positive drainage away
from the building. Which approach is generally most appropriate?
A. Create a completely level site with equal cut and fill
B. Orient the building perpendicular to the slope and eliminate all drainage paths
C. Align the building and grading strategy to work with the existing contours
while maintaining positive drainage
D. Import fill across the entire site
Answer: Align the building and grading strategy to work with the existing
contours while maintaining positive drainage
,Rationale: Working with existing topography generally reduces earthwork,
disturbance, and cost while preserving natural drainage patterns. The design
must still maintain appropriate drainage away from structures.
2. On a contour plan, closely spaced contour lines indicate:
A. Flat terrain
B. A drainage divide
C. A steep slope
D. A wetland boundary
Answer: A steep slope
Rationale: Contour spacing represents changes in elevation over horizontal
distance. Closely spaced contours indicate a greater elevation change over a
shorter horizontal distance.
3. A proposed accessible pedestrian route must cross a site with substantial
topographic variation. Which strategy should be considered first?
A. Maximize stairs
B. Ignore existing grades and use retaining walls everywhere
C. Locate the route along favorable existing contours to reduce excessive slope
D. Use loose aggregate throughout the route
Answer: Locate the route along favorable existing contours to reduce excessive
slope
Rationale: Aligning accessible routes with favorable topography can reduce
grading, retaining walls, ramps, and construction costs while improving
accessibility.
4. Which site-analysis layer is most useful for identifying areas where
development may cause soil erosion?
A. Existing vegetation color
B. Property ownership
,C. Slope, soil type, and drainage information
D. Building occupancy classification
Answer: Slope, soil type, and drainage information
Rationale: Erosion potential is strongly influenced by slope gradient, soil
erodibility, runoff, and drainage patterns.
5. A landscape architect is evaluating a site for a new public plaza. Which
factor should generally be considered first?
A. Pavement color
B. Furniture style
C. Site opportunities, constraints, circulation, drainage, and surrounding context
D. Planting palette
Answer: Site opportunities, constraints, circulation, drainage, and surrounding
context
Rationale: Successful site design begins with understanding the site's physical
and functional conditions before selecting detailed materials or furnishings.
6. A 1:4 slope is equivalent to approximately what percentage grade?
A. 4%
B. 20%
C. 25%
D. 40%
Answer: 25%
Rationale: Grade percentage equals rise divided by run multiplied by 100. A 1:4
slope equals 1 ÷ 4 × 100 = 25%.
7. A swale is primarily used to:
A. Increase groundwater contamination
B. Convey and manage surface runoff
, C. Eliminate all infiltration
D. Support structural foundations
Answer: Convey and manage surface runoff
Rationale: Swales are shallow, vegetated drainage features that can convey,
slow, infiltrate, and sometimes treat stormwater.
8. Which grading condition is most desirable immediately adjacent to a
conventional building foundation?
A. Positive slope toward the foundation
B. Level grade with no drainage outlet
C. Positive drainage away from the foundation
D. A depression against the foundation wall
Answer: Positive drainage away from the foundation
Rationale: Surface drainage should direct water away from foundations to
reduce hydrostatic pressure, moisture intrusion, and potential structural
problems.
9. A retaining wall is proposed on a steep slope. Which condition is most
important to address behind the wall?
A. Paint color
B. Drainage and hydrostatic pressure
C. Tree species alone
D. Pavement striping
Answer: Drainage and hydrostatic pressure
Rationale: Water retained behind a wall can create substantial lateral pressure.
Proper drainage, such as free-draining backfill and appropriate drainage outlets,
is essential.
10.Which stormwater strategy most directly reduces runoff volume at its
source?
