French rain garden layout plan

Quick answer：

A French rain garden layout plan typically includes the design and arrangement of vegetation, pathways, and water features to manage stormwater runoff. These gardens are designed to capture rainwater and infiltrate it into the ground, reducing runoff and filtering pollutants. The layout usually features a graded slope, with plants chosen for their ability to withstand both wet and dry conditions, and often includes a central water feature like a pond or fountain.
