Central Coast Council is undertaking an overland flood study for each of the contributing catchments that flow into the coastal lagoons of Wamberal, Terrigal, Avoca and Cockrone.

The study, which is concurrent with a study already underway in Green Point, West Gosford, Point Clare, Koolewong and Woy Woy Bay will identify flash flooding ‘trouble spots’ and assess what measures are required to reduce the risk of flooding during significant storm events.

Council Acting Director – Assets, Infrastructure and Business, Boris Bolgoff, said Council was seeking the community’s help to collect information on past flooding experiences and local flood knowledge to help with the selection of flood reduction measures.

“These suburbs have been identified as priority areas and this study will focus on stormwater that overwhelms the drainage network causing flash flooding and inundation from elevated water levels,” Mr Bolgoff said.

“Local knowledge and experience in times of flash flooding is critical to the success of this study.

“We would really like as many residents in these affected areas as possible to contribute to this study by completing the questionnaire, sharing their stories, photos or videos of flood events so we can gain a complete understanding of flooding in these local areas.”

Residents in areas covered by the study will receive a letter from Council containing a paper based survey and a reply paid envelope. Residents can either compete and post this survey or complete online at www.yourvoiceourcoast.com.

The study survey is now open and will close on Friday 10 August 2018.
