  1. A site inventory reveals a seasonal high water table at 18 inches below grade. Which design response is most appropriate for a proposed lawn area?

    Answer: Install subsurface drainage tiles before planting

    Subsurface drainage tiles lower the effective water table and allow turf to establish healthy root zones above saturated conditions.

  2. During a slope analysis, which slope range is generally identified as most suitable for active recreational facilities such as sports fields?

    Answer: 1-5%

    Slopes of 1-5% provide adequate surface drainage while remaining flat enough for safe athletic use and ADA-accessible paths.

  3. A Unified Soil Classification (USC) designation of 'CH' indicates which soil characteristic most relevant to site grading?

    Answer: High-plasticity clay with significant shrink-swell potential

    CH soils are fat clays with high plasticity index, making them prone to shrink-swell movement that can destabilize pavements and foundations.

  4. Which element of a solar analysis is most critical when siting a new passive-solar community building on a temperate northern-hemisphere site?

    Answer: Maximizing south-facing glass exposure

    South-facing glazing captures low winter sun for passive heating while roof overhangs can shade the same glass in summer.

  5. An inventory map shows a 100-year floodplain boundary crossing a proposed park site. Which agency's regulations primarily govern development within this zone?

    Answer: FEMA National Flood Insurance Program (NFIP)

    FEMA administers the NFIP and sets floodplain management regulations that local communities must adopt to participate in the program.

  6. During a site visit, a landscape architect notices a distinct change in vegetation from upland forest to sedge-dominated wetland. The transition zone between these communities is best described as:

    Answer: An ecotone

    An ecotone is the transitional zone between two adjacent ecological communities, often exhibiting high biodiversity from both communities.

  7. A topographic survey shows closed contour lines with hachure marks on a site. What landform do these lines represent?

    Answer: A depression or closed basin collecting water

    Hachure marks on closed contours indicate a depression where elevation decreases toward the center, unlike a hill where elevation increases.
