Ladder-like rainwater garden floor plan

Quick answer：

A ladder-like rainwater garden is a landscape design feature that incorporates stepped levels to collect and manage rainwater. The floor plan typically includes different levels with slopes that allow rainwater to percolate through layers of soil and vegetation, filtering it naturally before it replenishes groundwater or runs off into storm drains. This design helps manage stormwater runoff, reduce soil erosion, and provide a habitat for wildlife.
