Finish TradesCâu 270 / 700
To reduce stormwater runoff on a residential site, CALGreen encourages managing on-site drainage. One effective hardscape choice is:
a.Sloping all paving toward the street gutter
b.Sealing the entire yard with impermeable concrete
c.Directing downspouts straight onto the sidewalk
d.Using permeable paving that lets water infiltrate into the ground
Giải thích
Permeable paving lets rainwater soak into the soil, reducing runoff and helping recharge groundwater, which supports CALGreen stormwater goals. Sloping everything to the gutter, sealing the yard, or dumping downspouts on the walk all increase runoff instead of managing it on site.
