Does the development need an erosion and sediment control plan?
Yes. For an ACT dual occupancy DA, erosion and sediment controls are required. For a typical residential block under 0.3 hectares (3,000 m²), the plan must be prepared in accordance with the ACT EPA Preventing Pollution from Residential Building Sites – Builders Booklet.
The DA needs to show how soil, mud and sediment will be kept on the property during construction instead of washing onto the road or into stormwater drains.
For sites under 3,000 m², the plan should show at least:
- sediment controls, such as sediment fencing;
- a stabilised site access point;
- a designated cutting/wash area; and
- the water-flow path, such as contours.
For a simple dual occupancy, this information can be shown on another plan rather than requiring a completely separate drawing. More complex developments may require a separate Erosion and Sediment Control Plan.
