Rain gardens are specially shaped and planted areas designed to capture and manage stormwater. They can slow and filter runoff before it enters natural waterways or hold water temporarily, allowing it to soak slowly into the ground.
Designs range from simple swales to refined, engineered systems with concrete edging and layered soils. Rain gardens are an approved method for meeting Council requirements for stormwater attenuation next to impermeable surfaces like driveways, carparks, and courtyards.
I can calculate the size and depth of rain garden you’ll need to meet standards — for example, to manage runoff from a 1-in-10-year storm — and design it to complement your landscape beautifully.
