7. Which urban design strategy will most likely slow water runoff though an urban area and decrease the risk of downstream flooding?

Correct Answer: Correct answer is: (C) Preserve open areas with intact vegetation.

Exam Relevance: AP Environmental Science, Urban Planning Exams, Civil Engineering Exams

Difficulty: Moderate

Concept notes: Preserving open areas with intact vegetation helps to slow water runoff and reduce the risk of downstream flooding by increasing the amount of water that can be absorbed by the soil and vegetation.

Common Mistakes: A common misunderstanding is that urban infrastructure like wider streets, flat roofs, or large drainage pipes can effectively manage water runoff. However, these options do not address the root cause of increased runoff, which is the reduction of natural surfaces that can absorb water.

Explanations: Intact vegetation and open areas allow for water to be absorbed into the soil, reducing the amount of water that becomes runoff. This process, known as infiltration, helps to slow the flow of water and distribute it more evenly over time, thereby reducing the risk of downstream flooding. In contrast, urban surfaces like concrete streets, flat roofs, and large drainage pipes increase the speed and volume of water runoff, exacerbating the risk of flooding.

Option Analysis:

Option A: Wider concrete streets and sidewalks increase the impermeable surface area, leading to faster water runoff and higher risk of flooding.
Option B: Large flat roofs contribute to increased runoff as they do not absorb water, leading to faster drainage and higher risk of flooding.
Option C: Preserving open areas with intact vegetation allows for water absorption, reducing runoff and the risk of downstream flooding.
Option D: Large drainage pipes can quickly move water away but do not address the root cause of increased runoff, which is the lack of natural surfaces to absorb water.

8. Which of the following is one way to preserve land resources?

Correct Answer: Correct answer is: (A) Reduce urban sprawl.
