Penrith City Council is preparing a flood study for the Upper Byrnes Creek catchment. The study area is located between South Creek and Ropes Creek and includes the residential suburb of St Clair, Erskine Park and Colyton. 

This study will update Council’s existing flood information and help us plan for, predict and manage the risk of flooding across the catchment. To prepare the study, Council has engaged Advisian, an independent consultant specialising in flooding investigations. 

If your property is located within the study area and has experienced flooding, we invite you to complete our questionnaire and share your local knowledge and personal experience.

You can complete the questionnaire online below or download it here and:
