When designing a vehicular circulation plan, a 'throat length' refers to:
Answer: The distance from the street right-of-way to the first internal intersection or parking aisle
Throat length is the distance from the public street to the first conflict point inside a site, allowing vehicles to queue without blocking traffic.
Which of the following best describes a 'pedestrian shed' in transit-oriented development site planning?
Answer: The walkable catchment area, typically a quarter-mile radius, around a transit node
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.
In a site grading plan, what does a 'high point' along a swale or valley line indicate?
Answer: A location where runoff divides and flows in two opposite directions
A high point on a drainage swale is a watershed divide where stormwater splits and flows away in two directions.
The 'Rational Method' (Q = CiA) is used in site planning to calculate:
Answer: Peak stormwater runoff from a drainage area
The Rational Method estimates peak runoff (Q) as the product of runoff coefficient (C), rainfall intensity (i), and drainage area (A).
A 'brownfield' site in planning terminology is best defined as:
Answer: Previously developed land with known or suspected contamination that may complicate reuse
Brownfields are formerly industrial or commercial sites where real or perceived contamination hinders redevelopment, often eligible for EPA cleanup programs.
Which grading technique is used to transition between two different finished floor elevations without steps in an accessible route?
Answer: A ramp with handrails at a maximum 1:12 slope
ADA-compliant ramps with slopes no steeper than 1:12 (8.33%) and handrails are required when accessible routes must change elevation by more than ½ inch.
In LEED site planning, 'heat island effect' mitigation for paved surfaces is primarily achieved by:
Answer: Using high-albedo or permeable paving materials and providing shade
LEED credits for heat island reduction reward high-reflectance (high SRI) or open-grid permeable pavements and tree canopy shading over hardscape.
