What strategy will reduce the rate of stormwater runoff?
A: Install nonporous surfaces with high SRI values
B: Install exterior surfaces with high SRI values
C: Install a detention pond
D: Install water efficient irrigation systems

参考答案: C

本题解释:
A nonporous surface will increase the rate of stormwater runoff;High SRI materials are reflective and help reduce the heat island effect;A dry pond (detention pond) is used to store excess stormwater. Dry ponds are basins whose outlets have been designed to detain stormwater runoff for some minimum time (e.g., 24 hours). The stormwater will slowly seep into the ground to recharge aquifers or discharge as determined by the pond design to allow pollutants to settle. Unlike wet ponds, these facilities do not have a large permanent pool of water;Irrigation water runoff is not the same as stormwater runoff.Reference: LEED 2009 for New Construction and Major Renovations Rating System
