Introduction
The CLARB Landscape Architect Registration Exam assesses the competencies
required for independent professional practice. It evaluates skills in site analysis,
design, grading, construction documentation, and regulatory compliance. The
exam employs multiple-choice and scenario-based questions to test real-world
application and decision-making. Candidates must demonstrate critical thinking,
professional judgment, and a thorough understanding of ethical standards. This
practice assessment reflects the exam's emphasis on practical problem-solving
,and technical proficiency, preparing candidates for the responsibilities of licensed
landscape architects.
Section One: Questions 1–50
1. During a site visit for a new park development, a landscape architect
observes a wetland area that is not indicated on the provided survey. What is
the most appropriate first step?
A. Proceed with the design as planned since the survey is the legal document.
B. Notify the client and recommend a jurisdictional wetland delineation by a
qualified professional.
C. Design the park to avoid the area entirely without further investigation.
D. Submit the site plan for permit approval, noting the discrepancy.
🟢 Correct Answer: B. Notify the client and recommend a jurisdictional
wetland delineation by a qualified professional.
🔴 Rationale: A wetland not shown on a survey may be jurisdictional. The
presence of a potential wetland triggers the need for a formal delineation to
determine regulatory boundaries before design decisions are finalized,
ensuring compliance with clean water regulations.
2. A client requests a landscape design that includes an invasive plant
species because it is fast-growing and provides quick screening. How should
the landscape architect respond?
A. Install the plant as requested but do not include it in the plant schedule.
B. Refuse the project entirely.
C. Educate the client on the ecological risks and propose non-invasive
alternatives that achieve the same design goals.
D. Install the plant but plan to remove it after five years.
,🟢 Correct Answer: C. Educate the client on the ecological risks and propose
non-invasive alternatives that achieve the same design goals.
🔴 Rationale: The landscape architect has an ethical obligation to protect the
environment. Educating the client and offering alternatives fulfills the
professional duty while serving the client's functional needs.
3. When designing a pedestrian circulation system for a senior living
community, which principle is most critical?
A. Minimizing construction costs by using the shortest possible routes.
B. Providing direct, barrier-free routes with rest areas and clear wayfinding.
C. Using decorative paving to create a visually complex experience.
D. Maximizing the number of turns to increase interest.
🟢 Correct Answer: B. Providing direct, barrier-free routes with rest areas and
clear wayfinding.
🔴 Rationale: For senior populations, accessibility, safety, and ease of
navigation are paramount. Barrier-free routes, rest areas, and clear wayfinding
address mobility limitations and cognitive needs.
4. A landscape architect is preparing construction documents for a slope
stabilization project. The geotechnical report recommends a reinforced soil
slope. Which detail is most essential to include?
A. A decorative planting plan for the slope face.
B. A detailed section showing soil reinforcement layers, drainage, and facing
elements.
C. A perspective rendering of the final slope appearance.
D. A cost estimate for the reinforcement materials.
🟢 Correct Answer: B. A detailed section showing soil reinforcement layers,
drainage, and facing elements.
, 🔴 Rationale: For a reinforced soil slope, the construction documents must
convey the technical requirements for structural stability, including
reinforcement placement, drainage, and facing, to ensure the design intent is
correctly built.
5. In a commercial development, the local zoning code requires a 20-foot
landscape buffer adjacent to a residential zone. The site has only 15 feet of
available space. What is the best course of action?
A. Install a 15-foot buffer and request a variance.
B. Install a 20-foot buffer by reducing the building footprint.
C. Install a 15-foot buffer with a solid fence and document the non-
compliance.
D. Apply for a variance or seek an administrative adjustment before finalizing
the design.
🟢 Correct Answer: D. Apply for a variance or seek an administrative
adjustment before finalizing the design.
🔴 Rationale: The design cannot legally proceed as non-compliant. The proper
procedure is to seek relief from the zoning requirement through the
established variance process before completing design documents.
6. Which of the following is the primary purpose of a stormwater
management plan?
A. To maximize the amount of impervious surface on a site.
B. To control the rate and volume of runoff and improve water quality.
C. To eliminate all surface water from a site.
D. To increase the speed at which water leaves a site.
🟢 Correct Answer: B. To control the rate and volume of runoff and improve
water quality.
