Design scheme for a small rain garden in a park

Quick answer：

A rain garden is a depression in the ground that is designed to capture and infiltrate rainwater from roofs, driveways, and streets. Small rain gardens in parks can be designed to include native plants, which are adapted to the local climate and soil conditions, and can help manage stormwater runoff while providing aesthetic and environmental benefits. The design typically involves selecting the right plants, determining the size and shape of the garden, and ensuring proper soil and drainage systems. This can help improve water quality by filtering pollutants from the runoff before it reaches water bodies.
