Which of the following is a low impact development (LID) technique for rainwater management?
A . Storm inlet
B . Rain garden
C . Detention basin
D . Impervious pavement

Answer: B

Explanation:

Low Impact Development (LID) practices manage stormwater by using natural or man-made systems to filter and recharge stormwater into the ground12. A rain garden is an example of a LID technique for rainwater management3. It is a planted depression that allows rainwater runoff from impervious urban areas, like roofs, driveways, walkways, parking lots, and compacted lawn areas, to be absorbed. This reduces rain runoff by allowing stormwater to soak into the ground (as opposed to flowing into storm drains and surface waters which causes erosion, water pollution, flooding, and diminished groundwater).
