What are ways to reduce water pollution from runoff?(Choose 2)
A: Increasing the building footprint
B: Rain gardens
C: Impervious concrete hardscapes
D: Open grid paving

参考答案: BD

本题解释:
正确答案：B D
系统解析: B:A rain garden is used to capture runoff.

D:Open grid paving and pervious surfaces allow rainwater to percolate through the surface instead of running off.

A:Increasing the building footprint reduces the quantity of open space. By decreasing open space runoff can be increased since there is less natural area to absorb runoff.

C:Impervious materials increase runoff, as does increasing the size of the building footprint.
