Overview
Why is this project important?
Without proper controls in place, earthworks on building sites can cause increased sediment and nutrient runoff into nearby waterways. This can degrade the health of waterways and significantly impact aquatic environments and habitats.
The updated guidelines will help small-scale builders, certifiers, stormwater specialists and anyone working on construction sites that are less than 2,500m2 understand how to prevent erosion and sediment pollution and protect our waterways which is a key initiative under MEMS.
Councils can use these conditions in development approvals to ensure the approved development complies while construction is underway.
The standard conditions include a requirement for an Erosion and Sediment Control Plan (ESCP) to be prepared by a suitably qualified person.
Before works can commence, the certifier must be satisfied that the erosion and sediment controls in place are consistent with the ESCP. This brings greater consistency in erosion and sediment control on building sites across the State.
DPHI Planning plans to update the Guide to Complying Development and Pocketbook to provide further guidance on erosion and sediment control for complying development.
We presented alongside Shoalhaven Council at an Environmental Health Australia (EHA) webinar in September 2025. The session supported environmental practitioners and councils to strengthen their understanding of the importance of erosion and sediment control.
