What is stormwater?

    Stormwater is the water that accumulates during and after rainfall events. It can also include water from other sources such as irrigation, or other activities that involve the use of water. Stormwater can collect on surfaces such as streets, parking lots, and rooftops; and can flow into storm drains, streams, and rivers. In urban areas, where there is a lot of water-resistant surfaces, stormwater runoff can cause flooding and erosion, and can carry pollutants such as oil, chemicals, and trash into waterways, which can have negative impacts on aquatic life and public health. Managing stormwater is an important aspect of urban and suburban development and environmental management.

    What is a Stormwater Management Plan?

    A Stormwater Management Plan (SMP) is a strategic planning documents that aims to address stormwater problems and guide investments for reducing flood risk and maximising stormwater reuse, environmental protection, and public amenity. Local councils prepare SMPs with multi-objective planning, considering flood risk, water quality, and stormwater reuse.

    What is the importance of the Stormwater Management Plan?

    The Stormwater Management Plan (SMP) plays a crucial role in providing a strategic framework for integrated stormwater management in a catchment area. The SMP provides supports for catchment-scale stormwater planning, ensuring the consideration of adequate flood mitigation, water quality, and reuse opportunities.

    Who will approve the Stormwater Management Plan?

    The City of Adelaide will work with a consultant to develop the Stormwater Management Plan to comply with the Stormwater Management Authority (SMA) Guidelines. The Stormwater Management Plan will be assessed as complying with the Guidelines on Stormwater Management Planning and will be approved by the SMA.
