Healthy watercourses and waterfront land are vital to the community and environment. Because activities on waterfront land (called controlled activities) can threaten the health of our waterways, the department requires landholders to apply for a controlled activity approval for their works before they start.
Approvals usually contain conditions to minimise the impact of the activity or works on the waterway and adjoining land.
By requiring landholders to get a controlled activity approval before carrying out works on waterfront land, the department prevents activities that could alter water flow or quality, destabilise beds or banks of waterways, cause erosion, or disturb wildlife habitats.
Most controlled activities also need development approval from your local council. If this is the case, you will need to lodge what is known as an Integrated Development Assessment System Development Application (IDAS DA).
