Which of the following is NOT a consideration when calculating maximum impervious coverage?

The correct answer is the amount of parking spaces required. When calculating maximum impervious coverage, planners and architects focus on the physical characteristics of the site and the built environment, which includes the size of the lot, the area covered by buildings, and the area covered by pavement.

The size of the lot is a critical factor because it sets the maximum allowable area that can be developed while considering impervious surfaces. The area covered by buildings is also a primary component of impervious coverage, as buildings are typically the largest contributors to it. Similarly, pavement—whether for roads or parking—is another significant contributor to impervious surfaces.

Parking requirements, while they can certainly influence site planning, do not directly relate to the calculations of maximum impervious coverage. The focus is more on how much area is being rendered impervious by various surface types rather than the specific number of parking spaces that may or may not be required. Thus, the amount of parking spaces needed is not a direct consideration in this particular calculation.
