CLARB - Council of Landscape Architectural Registration Boards Inventory and Site Analysis Questions and Answers

Question 1

A landscape architect is conducting a site inventory for a proposed park on a parcel of land with varied topography. Which of the following data is MOST critical to collect for accurately analyzing slope and drainage patterns?

Accepted Answer

A topographic survey with 2-foot contour intervals.

Answer

A topographic survey provides detailed information on the land's elevation, contours, and slopes. This data is fundamental for understanding how water will flow across the site (drainage patterns) and for calculating the steepness of the terrain (slope analysis), which are critical for proper grading, accessibility, and stormwater management design. While other data are important for a comprehensive site analysis, the topographic survey directly addresses slope and drainage.

Question 2

During a Phase I Environmental Site Assessment (ESA) for a property intended for a new community garden, which of the following activities would typically be conducted?

Accepted Answer

Reviewing historical records, aerial photographs, and interviewing past owners.

Answer

A Phase I ESA is a non-intrusive investigation aimed at identifying potential or existing environmental contamination liabilities. This phase focuses on reviewing historical land use records, government databases, and aerial photos, as well as conducting a site visit and interviewing people familiar with the property's history. Soil and water sampling occurs in Phase II, and remediation design in Phase III.

Question 3

A landscape architect is analyzing a site for a new residential development. The local zoning ordinance specifies a maximum building height of 35 feet and a minimum front yard setback of 20 feet. These regulations are best classified as which type of site factor?

Accepted Answer

Legal constraints

Answer

Zoning ordinances, building codes, setbacks, easements, and other municipal regulations are legal constraints that dictate what can be built on a property. They are legally binding and must be adhered to in the design. Physical attributes refer to topography and geology, cultural context involves the surrounding community and history, and natural systems include hydrology and ecology.

Question 4

When inventorying a site's existing vegetation, which of the following characteristics is MOST important for determining which trees to preserve during the design and construction process?

Accepted Answer

The species, size, condition, and location.

Answer

A thorough vegetation inventory must document the species (to understand its characteristics and value), size (caliper and height), health/condition (structural integrity, disease), and precise location of existing plants. This information allows the landscape architect to make informed decisions about which trees are healthy, significant, and realistically salvageable within the proposed design and construction limits.

Question 5

A client has provided a landscape architect with a base map for a new project that includes property lines, easements, and existing utilities. To proceed with a detailed site analysis for grading and planting design, which of the following is the MOST critical missing piece of information?

Accepted Answer

Topographic data showing contours and elevations.

Answer

While all the listed items are important for a complete site analysis, topographic data (contours and elevations) is the most critical missing element for proceeding with grading design. Grading design is fundamentally about reshaping the land, which is impossible to do accurately or responsibly without knowing the existing landform. It is also essential for understanding surface drainage, which directly impacts planting design.
