Flood Study and Floodplain Risk Management Study and Plan

The City of Ryde is undertaking a Flood Study and Floodplain Risk Management Study which will provide the foundation for the development of a Floodplain Risk Management Plan. The Plan will be used by Council and other stakeholders to reduce the impact of flooding on the community, and assist in managing future development of the area.

An integral part of the study process is community consultation and involvement, Feedback from the community will incorporated in the development of the Floodplain Management Plan.

Background

The City of Ryde experienced several large storm events in 1984, 1986, 1988 and 1990, which caused widespread flooding. Heavy rainfall in 1998 and April 2003 also caused significant problems. Most of the stormwater pipes are in the latter part of their service life and generally do not have adequate capacity to accommodated large storm events. This can result in overland flows along streets and between developments.

Study Area

The study area includes five stormwater catchments, which flow into the Parramatta River. The five catchments contain major stormwater drainage systems, which generally originate in the residential areas south of Blaxland Road and Lane Cove Road, flowing from north to south.
