The concept design stage involves selecting the type, location and approximate size of stormwater treatments.

The functional design stage contains the next level of detail following the approved concept design.

The detailed design ​is based on the approved concept and functional designs, and involves documenting the design and functional elements with detailed design drawings and specifications.

Plants species used in raingardens, wetlands and swales must be perennial with an extensive fibrous root system.

Keep a close eye on construction to make sure the design drawings and specifications are followed. A few simple mistakes can cause plants to not survive or thrive.

You should generally inspect water sensitive urban design (WSUD) assets every three months for maintenance once the plants are established.

If you're developing or renovating a property that's subject to flooding, you'll probably need a planning permit from your council.

We’re constantly obtaining new flood information for the wider Melbourne area. We provide this information to councils, so they have accurate information about land that may be affected by flooding during severe storms.

If you've submitted your application for a planning permit to your local council we may have added some conditions on you being granted the permit.
