Public give short shrift to raising Lismore’s flood levee

PLANS to protect Lismore from flooding may have attracted a "relatively low number of submissions" during the exhibition period, but the message was clear, raising levee walls was not popular.

The Draft Floodplain Risk Management Study sought community feedback on a range of measures to control flooding, which included raising the levee wall at a number of locations.

The Floodplain Management Committee received only 60 submissions on the study, prompting the committee's Technical Working Group to recommend wider consultation in future planning stages.

The group felt key stakeholders, residents and businesses most likely to be impacted by flooding in the town, had not made submissions.

Those who did make submissions, generally supported more nature-based solutions to the flooding issue rather than structural or engineering flood modification measures.

"There is a clear concern about the negative impact that some structural measures have had, and could have, on parts of the community as well as support for increased community awareness and preparedness. Along with the push for nature-based solutions, this suggests that consideration of structural measures should not proceed any further," the working group reported.

The working group however, did not support removing structural measures from the plan at this stage due to the low response rate.

It said further investigation of the options did not commit council to construction, but offered further opportunity for wider community engagement.

"The TWG propose that the recommendations of the study should remain largely unchanged but with additional community engagement."
