In urban environments, paved surfaces such as roads, driveways and courtyards cover a significant area.
These ‘impervious’ surfaces do not allow rainfall to soak through them to the underlying soil and as a result contribute to larger amounts of stormwater entering into our streams than would otherwise naturally occur. These stormwater flows carry with them pollution that has been washed off from roads, pavements and roofs.
The rapid pace that stormwater is delivered to the stream contributes to bank erosion and habitat scouring.
To protect our streams from this occurring, we need to reduce the amount of ‘impervious’ surfaces in our urban areas so that less water and pollutants are washed off and delivered quickly to the stream.
One way to do this is to install porous pavements instead of traditional concrete pavements in our backyards and driveways. Porous pavements reduce the amount of runoff by allowing water to soak through the surface and into the underlying soil.
Your WSUD application tools
- If you are considering installing a porous/permeable paving as part of your Planning Application, see the materials and installation guide.
- Make sure your Site Layout Plan, Ground Floor Plan, and Roof Plan reflect the information contained in the WSUD Report (i.e. the STORM or MUSIC report).
- As a condition of your planning permit you will need to complete and submit a WSUD Site Management Plan. A WSUD SMP guide is available here: Keeping Our Stormwater Clean: A Builder’s Guide by Melbourne Water and the EPA Victoria.
