Question 1

In a USGS topographic map, contour lines that are spaced very close together indicate:

Accepted Answer

A steep slope with rapid elevation change

Answer

Closely spaced contour lines represent rapid elevation change over a short horizontal distance, indicating a steep slope.

Question 2

Which factor is most critical when siting a bioretention cell (rain garden) relative to a building foundation?

Accepted Answer

Minimum horizontal setback to prevent infiltrating water from undermining the foundation

Answer

Bioretention cells must be located at least 10 feet (typically) from foundations to prevent infiltrated water from saturating soils and causing structural damage.

Question 3

A 'program of requirements' document in site planning establishes:

Accepted Answer

The complete list of spatial needs, functional relationships, and performance criteria for a project

Answer

A program of requirements (or simply 'program') defines what spaces are needed, how large they should be, how they relate, and what performance standards they must meet.

Question 4

When calculating floor area ratio (FAR), which of the following is correct?

Accepted Answer

FAR = total floor area of all building stories ÷ total lot area

Answer

FAR is computed by dividing the total gross floor area of all stories by the area of the parcel, expressing how much building mass is allowed relative to lot size.

Question 5

Which type of retaining wall relies on the weight of its own mass to resist overturning and sliding?

Accepted Answer

Gravity retaining wall

Answer

Gravity retaining walls—including dry-laid stone and massive concrete walls—resist earth pressure through their own weight without relying on structural reinforcement.
