25
The loss of \_\_\_\_\_ is the most significant on-site consequence of erosion.
topsoil
26
Define turbidity in terms of sustainability.
Turbidity reduces sunlight penetration into water and leads to reduced photosynthesis in aquatic vegetation, causing lower oxygen levels that cannot support diverse communities of aquatic life.
27
Define remediation as it applies to sustainability.
Remediation is the process of cleaning up a contaminated site by physical, chemical, or biological means. This is typically applied to contaminated soil and groundwater.
28
\_\_\_\_\_ is an evaluation of a site's aboveground and subsurface characteristics, including structures, geology, and hydrology.
Site assessment
29
The best strategy for selecting a building site is to choose a \_\_\_\_\_ site.

31
Which organization addresses threatened and endangered wildlife and plants and maintains a list of the country's native plants and animals that are candidates for addition to the federal list.

Building density is the floor area of the building divided by the total area of the site (sq ft. per acre).
33
Redevelopment of \_\_\_\_\_\_ provides an alternative to developing on undeveloped areas and decreases the overall environmental impact of development.
brownfield sites
34
\_\_\_\_\_ environmental site assessment is an investigation that collects original samples of soil, groundwater, or building materials to analyze for quantitative values of various contaminants.

36
Bicycle racks and/or storage should be secured within \_\_\_\_\_ yards of a building entrance for at least \_\_% of all building users.

37
Define hybrid vehicles.

43
Define invasive plants in terms of sustainability.
Invasive plants are nonnative to the ecosystem and likely to cause harm once introduced. These plants are characteristically adaptable and aggressive, have a high reproductive capacity, and tend to overrun the ecosystems they enter.
