Question 1

When designing a vehicular circulation plan, a 'throat length' refers to:

Accepted Answer

The distance from the street right-of-way to the first internal intersection or parking aisle

Question 2

Which of the following best describes a 'pedestrian shed' in transit-oriented development site planning?

Accepted Answer

The walkable catchment area, typically a quarter-mile radius, around a transit node

Answer

A pedestrian shed is the area accessible on foot—usually a quarter-mile (5-minute walk)—from a transit stop, used to define TOD planning boundaries.

Question 3

In a site grading plan, what does a 'high point' along a swale or valley line indicate?

Accepted Answer

A location where runoff divides and flows in two opposite directions

Answer

A high point on a drainage swale is a watershed divide where stormwater splits and flows away in two directions.

Question 4

The 'Rational Method' (Q = CiA) is used in site planning to calculate:

Accepted Answer

Peak stormwater runoff from a drainage area

Answer

The Rational Method estimates peak runoff (Q) as the product of runoff coefficient (C), rainfall intensity (i), and drainage area (A).

Question 5

A 'brownfield' site in planning terminology is best defined as:

Accepted Answer

Previously developed land with known or suspected contamination that may complicate reuse

Answer

Brownfields are formerly industrial or commercial sites where real or perceived contamination hinders redevelopment, often eligible for EPA cleanup programs.
