Design Case of a Small Rain Garden

Quick answer：

A small rain garden is a landscaped depression designed to capture and retain stormwater runoff. It typically includes plants that can withstand both dry and wet conditions, as well as soil and other materials to filter pollutants from the water. Design cases involve considerations such as the size of the garden, soil type, local climate, and the types of plants chosen. Effective design can reduce runoff, improve water quality, and provide aesthetic and environmental benefits.
