Parking Layout
Hi everyone, little help needed.
PPD exam is coming up and I am yet to study parking. Can someone kindly guide me what all to cover under parking? From what I understand, it is basic parking layout, bay sizes, bay area driveway sizes, 90 vs angled parking, handicap parking location.
What is the best source to study for this? Is there something I missed?
Thanks in advance!

Hi Arjumand,
Few things that I remember (but please double check this info =)
1. Difference between 90 degree parking and angled parking - which one will fit more cars (90 degree), which one is easier to park (angled parking).
2. Handicap parking location - easy access to the building, and connected to an accessible route.
3. Accessible routes - from parking to building, it is covered by ADA.
4. Percentage of accessible parking required - IBC accessibility chapter.
5. Curb cut - where is the best location to have the entrance of your site?
6. Parking lot min/ max slope - what is the minimum slope for good drainage.
7. Best location for parking - depends on topography (best in a not very steep area), and building location.
8. Number of parking spots - covered by the zoning ordinance.
Book: The Architect's Studio Companion has a dedicated chapter about parking.
Good luck!

What is the most efficient parking lot layout?
One-way or two-way traffic?
Perpendicular, parallel, or angled?
One-way traffic angled parking offers the most parking spaces on a given site because of the narrower aisles (narrow one-way aisles don't really work in 90-degree stalls because there's not enough room to turn.) See here. See here too. See here too.
But other times 90-degree parking is more efficient! See here.
So which one do you answer in the exam? Angled parking, one-way aisles (75 degrees is the most efficient as far as the exam is concerned). NCARB maintains a Wiley publisher bias and that's what the Architect's Studio Companion tells us (Wiley book).
To summarize. . in reality, the most efficient layout is a bit more site-specific and 75 degrees is most efficient sometimes, but for this exam, 75 degrees is optimal. Angled parking is also more convenient and safer. . . up to an angle of 45 degrees. . . .For angled parking, keep the angles between 45 and 75 degrees.
