Question

Installing which of the following will increase the quantity of the rainwater that is discharged from a site?

A. Vegetated roof
B. Porous pavers for parking lots
C. Concrete sidewalks and parking areas
D. Bioswales and ram gardens with native plants

Answer

C. Concrete sidewalks and parking areas

Explanation

Installing concrete sidewalks and parking areas will increase the quantity of the rainwater that is discharged from a site. Rainwater is the water that falls as precipitation on a site. Rainwater discharge is the amount of rainwater that leaves a site as surface runoff or subsurface flow.

Rainwater discharge can affect the quantity and quality of water resources downstream by causing erosion, flooding, sedimentation, pollution, and habitat loss. Concrete sidewalks and parking areas are examples of impervious surfaces that prevent rainwater from infiltrating into the soil and increase rainwater discharge by creating more runoff.
