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.

What have we achieved so far?

DPHI Planning has updated the guidelines for erosion and sediment control on building sites.

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.

DPHI Planning has also updated a set of standard conditions of development consent (which councils can also access in the planning portal).

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.

We published a short video outlining the Guidelines and importance of effective erosion and sediment control.
