A small grocery store has limited space in front of it to accommodate the cars of the customers. The available parking lot space is 150 feet wide and 60 feet deep. The owners want to develop one W4 module of standard cars with handicapped car spaces, with a parking angle of 70 degrees. The bottom row of this module will contain standard car spaces and the two handicapped car spaces, using the entire available parking lot width of 150 feet. The upper row of this module will contain all standard car spaces, allowing for cross aisle and curb space of 20 feet on either side. The SW for a standard car is 8′ 6″. The SW for a handicapped car space is 12′. The SD for a standard car as well as for a handicapped car space is 20′. Answer the following questions and show all supporting work.

a) The number of standard car spaces in the bottom row will be ________________

b) The number of standard car spaces in the upper row will be _________________

c) The total area that is “wasted”, based on the parking angle, for both rows will be ___________

The owners want to explore the option of increasing the “free” space in the parking lot in front of the store, and are interested in evaluating a parking lot layout containing one module (W4) of compact (small) cars instead of standard cars. The parking angle will be increased to 75 degrees. The cross aisle and curb space will now be reduced to 15 feet on either side, as applicable to the upper row of cars. The two handicapped car spaces, with the same parameters as before, will still remain in the bottom row of this module. The SW of a small car is 8′ and the SD of the small car is 17′. Answer the following questions.

d) The number of small car spaces in the bottom row will be ________________

e) The number of small car spaces in the upper row will be _________________
