Byron Shire Council recently sought the assistance of BMT WBM to prepare a Floodplain Risk Management Study and Plan for the Belongil Creek catchment, which includes the town of Byron Bay in northern New South Wales.
The iconic town of Byron Bay is susceptible to flooding from intense short duration storms over the town, flooding from Belongil Creek and ocean storm tide events. Managing this “triple threat” of flooding in a complex coastal estuarine environment presented unique floodplain management opportunities and constraints for mitigating risks to life and property.
In Byron Bay, floodplain management measures had to be developed carefully against the backdrop of an active community who are keenly interested in water quality, flood resilience and long-term climate solutions.
The mitigation measures developed to manage flood risk were uniquely tailored to the Byron Bay community, aiming to reduce flooding for major and minor events, provide immunity against ocean storm tides, reduce the nuisance associated with stormwater flooding and remain adaptable to projected sea level rise.
The Floodplain Risk Management Study and Plan was adopted by Byron Shire Council in April 2015.
