rain garden plan

Quick answer：

A rain garden plan refers to the design layout of a rain garden, which is a shallow depression in the ground designed to capture rainwater runoff. These gardens use native plants and are intended to reduce stormwater runoff and improve water quality by allowing rainwater to infiltrate into the ground instead of flowing into storm drains. The plan includes details such as the size, shape, and placement of the garden, the types of plants to be used, and the necessary soil preparation.
