Flood planning in Blacktown — common questions
Is my Blacktown property in a flood planning area?
Parts of Blacktown have flood planning areas, particularly along Eastern Creek, Bells Creek, and Ropes Creek. New release areas in the north-west may also have flood-affected land near natural watercourses.
What flood risks exist in Blacktown?
Eastern Creek, Bells Creek, and their tributaries are the main flood sources. Overland flow in low-lying areas of established suburbs also creates flood risk during intense rainfall events.
Does flood risk affect new housing estates in Blacktown?
New release areas must address flood risk at the subdivision stage. Some lots near natural watercourses may be in flood planning areas. Check your specific lot before purchase.
Can I build a granny flat on a flood-affected Blacktown property?
Under SEPP Housing 2021, flood control lots cannot use the CDC pathway. Check your flood status above, then use the granny flat checker for full eligibility assessment.
