  1. In a planting plan, a landscape architect specifies 'Quercus rubra — 3" Cal., B&B.' What does 'B&B' indicate about the plant material?

    Answer: The plant is balled and burlapped

    B&B (balled and burlapped) indicates the tree's root ball was dug with soil intact and wrapped in burlap for transport and planting.

  2. Which site analysis factor most directly determines the feasibility of on-site septic system installation?

    Answer: Soil percolation rate

    Soil percolation rate determines how quickly water drains through soil, which is the primary criterion for septic system feasibility and sizing.

  3. A landscape architect is conducting an inventory of a site with a seasonal high water table at 18 inches below grade. Which design approach is most appropriate for planting trees in this area?

    Answer: Plant in raised berms or mounds

    Planting in raised berms or mounds elevates the root zone above the seasonal high water table, preventing root suffocation in saturated soils.

  4. On a construction document, a landscape architect draws a section through a retaining wall. What is the PRIMARY purpose of this drawing?

    Answer: Illustrate the internal structure and footing details

    Section drawings cut through structures to reveal internal construction details including footings, reinforcement, and drainage elements not visible in plan or elevation.

  5. The Unified Soil Classification System (USCS) classifies soils primarily based on which two characteristics?

    Answer: Grain size and plasticity

    The USCS classifies soils using grain size distribution (gravel, sand, silt, clay) and plasticity characteristics (Atterberg limits) to determine engineering properties.

  6. Which riparian buffer vegetation strategy provides the greatest water quality improvement by removing agricultural nutrients from field runoff?

    Answer: Dense herbaceous filter strip with native grasses

    Dense native herbaceous filter strips slow runoff velocity, promote infiltration, and uptake nutrients through active plant growth and dense root systems.

  7. When calculating earthwork volumes on a grading plan, what does the 'cut' volume represent?

    Answer: The difference between existing and proposed contours

    In earthwork calculations, 'cut' represents the volume of soil removed where proposed grade is lower than existing grade.
