Final answer:
Yes, the lower area can be used as a parking lot in this case. Building an apartment building on stem walls parallel to the flow of water with the lowest floor 8' above grade allows for the space beneath the lowest floor to be utilized for parking.
Step-by-step explanation:
Yes, the lower area can be used as a parking lot in this case. Building an apartment building on stem walls parallel to the flow of water with the lowest floor 8' above grade allows for the space beneath the lowest floor to be utilized for parking. Stem walls are structural walls that elevate the building above the ground, and in this scenario, they can provide additional space for parking while keeping the building above the potential flow of water.
This design is often used in areas prone to flooding, as it helps protect the building from water damage. By elevating the lowest floor above grade, the building is less likely to be affected by rising water levels. However, it's important to consider proper drainage and flood mitigation measures when constructing in flood-prone areas.
