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

参考答案: AC

本题解释:
A A rain garden is used to capture stormwater runoff.
B Increasing the building footprint reduces the quantity of open space. By decreasing open space stormwater runoff can be increased since there is less natural area to absorb runoff.
C Open grid paving and pervious surfaces allow stormwater to percolate through the surface instead of running off.
D Impervious materials increase stormwater runoff, as does increasing the size of the building footprint.
