Ashbourne residents have been significantly impacted by both locally generated overland stormwater flows and floodwaters from Bull Creek breaking its banks. These events, which occurred in 2010, 2016, and most recently in 2022, have affected several homes in the town. Many residents have had stormwater or floodwaters enter or nearly enter their premises during these storms, causing repeated concern and disruption for the community.

Alexandrina Council is currently working with the Ashbourne community to deliver a long-term solution to the ongoing flooding issues. Council is progressing complex planning and design stages to ensure the right infrastructure is delivered for the benefit of the community.
