A program of maintenance works is currently underway by Council to ensure the unobscured flow of stormwater runoff in urban channels at a number of high priority sites.  

Central Coast Council Director Environment and Planning, Alice Howe said this annual works program plays a role in flood mitigation and management of natural waterways.

“These works help to maintain effective drainage at these creeks and limit the impact of flooding to surrounding properties, as well as improving water quality and providing other benefits to wildlife” Dr Howe said.

“A range of activities will be carried out, such as aquatic weed control and removal, removal of waterway obstructions such as debris, sediment, litter, and fallen trees, bush regeneration, and vegetation maintenance works on the creek or channel banks and corridors. Selected tree removal is considered through Council's Urban Stormwater Maintenance Environmental Assessment process to improve channel function and allow for access for maintenance activity.”

These works are being undertaken from 20 March to 30 June 2023 (weather dependant), with limited impact to traffic, pathways or public reserves.

Maintenance works are scheduled at the following locations:
•    Copacabana - Del Rio Drive / Del Monte Place 
•    Wyoming - Wingello Creek
•    Wyoming - Brady’s Gully Creek
•    Wyoming - Wyoming Creek
•    Narara - Koninderie Parade 
•    Erina - Terrigal Drive (Worthing Road / Jessie Hurley Drive)

The sites are identified through Flood Risk Management Plans and Studies. Prioritisation in this year’s work schedule is based on condition inspection reports, risk analysis, available budget and resources.

Other key urban stormwater channels across the region have intermittent inspections, with maintenance works undertaken on a needs-basis to remove any build-up of sediment or other obstructions to ensure that the channel and drainage infrastructure continue to function effectively.  

Council also responds to community reports of any stormwater channel blockages or issues and carries out inspections following major storm or flood events.

Council Administrator Rik Hart said proactive management of stormwater channels assists in preparing for extreme weather and mitigating risks.

“The significant rainfall and flooding events that the Coast experienced in 2022 demonstrated how valuable these proactive works are to help reduce risk of flooding in urban areas,” Mr Hart said.

“However, this is one piece of the puzzle in building flood resilience, and we all have a part to play. 

“I encourage residents that live alongside our waterways to be aware of their own risks, reduce these where possible and prepare a custom flood plan and emergency kit.

“Council’s website has information and links to helpful resources, including an interactive online flood mapping tool to help identify how various river heights will impact specific properties and the surrounding roads and spaces.”
