Flood Studies

Flooding can cause significant damage to property and infrastructure and pose a risk to life. Council has identified the areas in which flooding may be a risk. These flood studies and maps will help us guide development decisions, identify potential mitigation options and options to improve stormwater infrastructure and community safety.

All of our current flood studies and mapping are available to view and download below. The date each individual study was endorsed by Council is provided in brackets. If you are not sure about why we have done these, or what some of the terminology means, visit our Frequently Asked Questions page.

Studies and programs

Margate Rivulet Hydraulic Assessment (September, 2021)

The Margate Rivulet Hydraulic Assessment was undertaken to identify flooding and associated risks across the catchment for a range of storm event probabilities. The information gathered in the report will be used to inform future planning decision for the region and potential mitigation strategies as required.

Coffee Creek Hydraulic Assessment (September 2021)

The Coffee Creek Hydraulic Assessment was undertaken to investigate the flood risk within the catchment and to undertake an erosion risk assessment of the waterway and to identify how future development within the catchment may further increase flood and erosion risks. The outcome of this study provides Council with clear directions on how the identified risks can be managed and reduced.

Whitewater Creek Flood Study (June 2020)

The Whitewater Creek Flood Study was undertaken to understand the flood risks associated with a range of storm event probabilities within the catchment.

Kingston CBD and Blackmans Bay Catchment Resilience Programs (June 2020)

These studies describe the flood risk characteristics under existing and future climate conditions and identifies ‘hotspot’ areas for flooding. This information  provides Council with flood intelligence that can be used in the preparation of planning controls for development applications, understanding the flood risks associated with a range of event probabilities and developing catchment resilience strategies, including mitigation measures.

Adventure Bay Flood Study (May 2020) 

The flood risks in the Captain Cook Creek Catchment was mapped for a range of catchment, coastal and coincidental flood events under both existing and future climate conditions. This study forms an important part of Council’s commitment to climate change adaptation works in the area.

Snug River Flood Study (May 2020)

The Snug River Flood Study have mapped the flood behaviour for a range of  coincidental storm events under both existing and future climate conditions in the Snug River catchment. The outcomes of this study will be used by Council to inform future land use planning, emergency management, budget considerations and works projects.

Kingston Beach Flood Mitigation Investigation  (November 2021)

The Kingston Beach Flood Mitigation Investigation Report “defines the revised flood behaviour under existing and future potential climate conditions in the Browns River catchment for a full range of design catchment flood, coastal flood and coincident flood events using the latest methodologies and climate change recommendations”.

The report includes possible mitigation options which will be presented to the community in early 2024 for public consultation prior to any consideration by Council to implement any option.  A considerable benefit of the report is that about 150 homes are now outside the designated flood extent for the 1% AEP storm event.   The Study and Flood Maps Series can be viewed below.

Tramway Creek Flood Study 2023

The Tramway Creek Flood Study was undertaken to identify flooding and associated risks across the catchment for a range of storm event probabilities. The information gathered in the report will be used to inform future planning decisions for the region and potential mitigation strategies as required.
