The Electoral College gives a numeric advantage in the election of the president to the smaller states, as the minimum number of electors for the small states is three compared to one for the election of representatives. On the other hand, the winner-take-all method of voting favors the larger states.
This clear width minimum is the minimum width for passage and not a sidewalk width recommendation [PROW Guide, Sec. 3.2.1]. The clear width is the width of section of the walkway that is completely free of obstacles, vertical obstructions and protruding objects. The 36 inch width is the minimum width required to provide sufficient space for a person who uses mobility aids to travel within the restricted space [ADAAG, Sec. 4.3]. However, restricting the pedestrian zone to 36 inches prevents passing and does not allow for 2-way travel.
Measure the length and width of your walkway to determine the square footage. Multiply the length times the width. For example, a walkway 3 feet wide by 40 feet long is 120 square feet. Convert the square footage to cubic feet, then cubic yards. Divide your 2-inch depth by 12 to get 0.17. Multiply 0.17 times the square footage.
