CPH Landscape Design and Installation Flashcards

In landscape design, a 'sight line' is best described as:

Answer: A visual path that guides the eye toward a focal point

A sight line is a carefully controlled visual path that directs the viewer's eye through the landscape to a focal point or beyond.

At approximately what slope percentage do most horticulturists recommend implementing erosion control measures for planted areas?

Answer: Greater than 25%

Slopes exceeding approximately 25% (roughly a 1:4 ratio) typically require erosion control measures such as ground covers, retaining walls, or erosion-control matting.

In landscape design, 'scale' is best defined as:

Answer: The proportional relationship between landscape elements and their surroundings

Scale describes the proportional relationship between landscape elements, the built environment, and the human figure, and is key to creating a cohesive design.

A 'dry-laid' stone wall is characterized by which construction method?

Answer: Stones interlocked without mortar, relying on gravity and friction

A dry-laid wall is constructed without mortar; the stones' weight and interlocking shapes provide structural integrity.

When selecting plants for a landscape site, which factor is MOST important to evaluate first?

Answer: Site conditions including hardiness zone, soil, and light exposure

Matching plant selections to site conditions—climate, soil type, drainage, and light—is the single most critical factor for long-term plant success.

What does 'phased installation' mean in a landscape construction project?

Answer: Completing the landscape in planned stages over time to manage cost and sequencing

Phased installation breaks a landscape project into logical stages implemented over time, allowing clients to manage budget while progressing toward the complete design.
