Video Resources


Learning Objectives

  1. Understand the landscape design process
  2. Know how to conduct a site analysis
  3. Interpret grading plans and symbols
  4. Understand basic design principles

Part 1: The 5 Phases of Landscape Design

  1. Client Consultation – Needs, wants, budget, maintenance expectations
  2. Site Analysis – Survey existing conditions, utilities, drainage, sun/shade
  3. Conceptual Design – Bubble diagrams, use areas, circulation
  4. Design Development – Detailed drawings, plant selection, irrigation
  5. Construction Documentation – Final plans, materials list, permits

Key Terms

  • Bubble Diagram: Preliminary sketch showing areas and relationships
  • Hardscape: Non-living elements (patios, walls, walkways)
  • Softscape: Living elements (plants, trees, lawns)
  • Grading: Reshaping land contours for drainage
  • Setback: Required distance from property line

Part 2: Site Analysis

Always call 811 before digging!

Document These:

  • Property boundaries and dimensions
  • Existing structures and hardscape
  • Utilities (overhead and underground)
  • Sun exposure patterns
  • Drainage patterns
  • Soil type and condition
  • Legal considerations (easements, setbacks, HOA)

Part 3: Reading Grading Plans

Contour lines close together = steep slope

Common Symbols:

  • TC = Top of Curb
  • FL = Flow Line
  • TW = Top of Wall
  • FF = Finished Floor
  • HP/LP = High Point/Low Point

Slope Formula: Rise divided by Run = Percentage

  • Minimum drainage from structures: 2%
  • Max for lawns: 25%
  • Max for ADA walkways: 5%

Part 4: 7 Principles of Design

  1. Unity – Cohesive, connected
  2. Balance – Symmetrical or asymmetrical
  3. Proportion – Scale to surroundings
  4. Rhythm – Repetition creates movement
  5. Focalization – Focal points draw attention
  6. Transition – Gradual change
  7. Line – Straight=formal, Curved=informal

Interactive Quiz

1. Contour lines close together indicate:

2. Minimum drainage slope from buildings:

3. Before excavation, you must:

4. Bubble diagrams are used in which phase?

5. Which principle uses repetition for movement?


Key Concepts to Memorize

  1. 5 Phases: Consultation then Site Analysis then Conceptual then Development then Documentation
  2. Minimum drainage slope: 2%
  3. Always call 811 before digging
  4. Contour lines close = steep slope
  5. Slope = Rise divided by Run
