The correct answer is that a rain garden helps to manage stormwater and reduce runoff. Rain gardens are specifically designed to collect and absorb rainwater from impervious surfaces like roofs, walkways, and driveways. By allowing water to infiltrate the soil, rain gardens can effectively reduce the volume and speed of runoff, which helps to prevent flooding, erosion, and water pollution in nearby waterways.

Rain gardens also utilize native plants, which can further enhance their ability to absorb moisture and filter pollutants. This natural approach not only aids in managing water but also promotes groundwater recharge, improving the overall health of the local ecosystem.

While increasing property values and providing a habitat are potential indirect benefits of well-designed green infrastructure, the primary function and most significant benefit of a rain garden is its role in stormwater management. Furthermore, rain gardens typically do not create additional parking space, as they are functional landscape features rather than utilitarian spaces.
