What design decision would MOST help reduce the quantity or improve the quality of
stormwater runoff?
A: Clustering the development together
B: Planting trees to provide cover for hardscapes
C: Installing high albedo parking lot surfaces
D: Mulching around landscape areas

参考答案: A

本题解释:
While planting trees to provide cover for hardscapes can also reduce
stormwater runoff to some degree, the intent of the question is to learn about
clustering the development together.

High albedo surfaces help reduce the heat island effect.

Mulching is a way to retain water but it is not the \'most\' helpful design
decision.

Notes:
Reducing hardscapes can be accomplished by clustering the parts of the development.
This has the effect of reducing the impermeable area from which stormwater can run
off.
How clustering the development reduces impervious surfaces:
Imagine a 100 acre square college campus that has 1 building in each corner of the
campus with roads and sidewalks connecting them to each other.
Now consider the same 100 acre square college campus where all 4 buildings are in
the same corner. The roads and sidewalks are shorter to each building, which reduces
the quantity of impervious surfaces.
