Which design strategy best supports urban biodiversity in a highly impervious downtown streetscape?
Answer: Incorporating pollinator gardens, layered plantings, and permeable surfaces
Layered, diverse plantings with permeable surfaces create habitat niches for insects, birds, and other urban wildlife while managing stormwater.
The Safe Drinking Water Act's Source Water Protection program is relevant to landscape architects primarily because:
Answer: It restricts land uses near public drinking water intake zones
Source water protection areas around drinking water intakes have restricted land uses and require careful stormwater and chemical management to prevent contamination.
A landscape architect assessing ecological connectivity should prioritize which corridor type for linking fragmented habitat patches?
Answer: Riparian corridors with native vegetation following stream networks
Riparian corridors provide linear habitat with moisture, food, and cover along stream networks, serving as the most effective natural movement corridors for diverse wildlife.
Which calculation method is used in the Rational Method (Q = CiA) to estimate peak stormwater runoff?
Answer: Q = peak flow rate in cubic feet per second
In the Rational Method, Q represents peak runoff rate in cubic feet per second, calculated from runoff coefficient (C), rainfall intensity (i), and drainage area (A).
Environmental Justice (EJ) considerations require landscape architects to:
Answer: Ensure equitable distribution of green space and environmental benefits across all communities
Environmental Justice principles require that no community bear a disproportionate share of environmental burdens and that all populations have equitable access to environmental benefits.
When restoring a prairie ecosystem, the recommended seeding rate is adjusted based on:
Answer: Seed purity, germination rate, and target plant density
Pure Live Seed (PLS) calculations account for seed purity and germination rate to ensure the correct density of viable seeds per acre is applied.
Which approach to slope stabilization is most ecologically appropriate for a disturbed streambank in a sensitive watershed?
Answer: Bioengineering techniques using live stakes, brush layers, and native plantings
Bioengineering uses living plant material to provide immediate erosion control while establishing permanent vegetative cover that improves habitat and water quality over time.
