LARE LARE Section 3

Question 1

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

Accepted Answer

The plant is balled and burlapped

Answer

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

Question 2

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

Accepted Answer

Soil percolation rate

Answer

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

Question 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?

Accepted Answer

Plant in raised berms or mounds

Answer

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

Question 4

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

Accepted Answer

Illustrate the internal structure and footing details

Answer

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

Question 5

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

Accepted Answer

Grain size and plasticity

Answer

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