CPP Facility Design & Planning 2 — Questions and Answers
Question 1: What is the recommended minimum clear height for a standard parking level to accommodate most passenger vehicles?
- 6 feet
- 7 feet (Correct answer)
- 8 feet 2 inches
- 9 feet 4 inches
Correct answer: 7 feet
A 7-foot minimum clear height accommodates most passenger vehicles, though ADA-accessible spaces and van routes require 8 feet 2 inches.
Question 2: Which parking structure configuration offers the most efficient land use by stacking floors directly above one another with level floor plates?
- Ramp-flat design
- Split-level design
- Flat-plate design (Correct answer)
- Helix ramp design
Correct answer: Flat-plate design
Flat-plate design provides completely level floor plates on each level, maximizing structural efficiency and allowing uniform stall layouts.
Question 3: When designing pedestrian pathways through a parking facility, which principle from CPTED (Crime Prevention Through Environmental Design) is most critical?
- Minimizing the number of exits
- Maximizing natural surveillance sight lines (Correct answer)
- Using dark colors on walkway surfaces
- Reducing lighting levels to save energy
Correct answer: Maximizing natural surveillance sight lines
Natural surveillance—ensuring pedestrians and activities are visible from multiple vantage points—is the cornerstone CPTED principle for parking facilities.
Question 4: A parking structure is being planned in a coastal region with high humidity. Which waterproofing approach is most critical for long-term structural integrity?
- Applying a single-layer epoxy paint coating
- Installing traffic-bearing membrane systems on exposed decks (Correct answer)
- Using standard concrete mix without additives
- Relying solely on drainage slopes
Correct answer: Installing traffic-bearing membrane systems on exposed decks
Traffic-bearing membrane systems on exposed decks prevent water and chloride intrusion, which is the leading cause of reinforcement corrosion in parking structures.
Question 5: In parking facility planning, what does a 'module width' refer to?
- The total width of one driving aisle only
- The combined width of two rows of stalls plus the aisle between them (Correct answer)
- The distance between structural columns
- The width of a single parking stall
Correct answer: The combined width of two rows of stalls plus the aisle between them
Module width is the combined dimension of two stall rows plus the shared driving aisle, and it is the fundamental unit of parking structure bay planning.
Question 6: Which ADA requirement specifically applies to van-accessible parking spaces in a parking structure?
- A 5-foot access aisle adjacent to the space
- A minimum 98-inch (8-foot 2-inch) clear height on the route to the space (Correct answer)
- A maximum 2% slope within the stall
- A minimum stall width of 10 feet
Correct answer: A minimum 98-inch (8-foot 2-inch) clear height on the route to the space
Van-accessible spaces require a minimum 98-inch clear height along the entire accessible route from entry to the van space to accommodate wheelchair lift-equipped vans.
Question 7: When evaluating a site for a new parking structure, what is the primary purpose of a traffic impact study?
- To determine the interior lighting requirements
- To assess how the facility will affect surrounding street capacity and safety (Correct answer)
- To calculate the structural load requirements
- To identify ADA compliance gaps
Correct answer: To assess how the facility will affect surrounding street capacity and safety
A traffic impact study evaluates how vehicles entering and exiting the facility will affect nearby intersections, queuing, and pedestrian safety.
