A rain garden is a specially designed, shallow, planted area that absorbs and filters rainwater runoff from impervious surfaces like roofs, driveways, sidewalks, or streets. Rain gardens address key environmental challenges by managing stormwater runoff, reducing flooding, and preventing water pollution. They capture and filter runoff from impervious surfaces, reducing the volume of water entering storm drains and removing pollutants before they reach waterways.
By promoting water infiltration, rain gardens help recharge groundwater and mitigate soil erosion. Planted with native species, they create habitats for wildlife, support pollinators, and enhance urban green spaces, contributing to biodiversity and cooling urban heat islands. Additionally, rain gardens improve community aesthetics and raise awareness about sustainable water and ecosystem management.
