Flood planning in Parramatta — common questions
Is my Parramatta property in a flood planning area?
Significant parts of Parramatta are in flood planning areas, particularly along the Parramatta River, Clay Cliff Creek, and Toongabbie Creek. The Parramatta CBD itself has flood-affected areas. Check your specific address above.
What are the main flood risks in Parramatta?
The Parramatta River catchment creates the primary flood risk. The river has significant flood history, with major events in 2021 and 2022. Overland flow during intense rainfall also affects parts of the LGA away from watercourses.
Does the Parramatta River flood study affect development?
Yes. Properties in the Parramatta River flood planning area face development controls including minimum floor levels, flood-compatible construction, and formal flood risk assessment for certain development types.
Can I build a granny flat on a flood-affected Parramatta property?
Under SEPP Housing 2021, flood control lots are excluded from the CDC pathway. A DA with flood risk assessment is required for secondary dwellings on flood-affected land in Parramatta.
