National and State Governments have updated flooding and stormwater management guidance.
This includes significant changes to the:
- State Planning Policy (2017)
- 2016 revision of Australian Rainfall and Runoff (ARR)
- Queensland Urban Drainage Manual Fourth Edition (2017) and
- Finalisation of ARR Book 9 - Runoff in Urban Areas (May 2019).
In response, we have prepared a package of Flooding and Stormwater Management information. This includes a set of guidelines and supporting technical documents. It gives you guidance on:
- the management of stormwater quality, quantity and drainage
- the code and policy requirements of a future Sunshine Coast Planning Scheme.
Our information supports the codes and policies of the planning scheme. It will help you with the development application process.
The codes and policies of the planning scheme are not provided for consultation. This will happen at a future date as part of the consultation for a planning scheme amendment.
We need your feedback
We're asking industry to provide feedback on these documents and tools:
- Flooding and Stormwater Management Guidelines (July 2019)
- A Review of Simple Peak Flow Estimation Methods for use on the Sunshine Coast following the release of ARR2016 (May 2018)
- Spreadsheet tool: DRAFT - Sunshine Coast Council Peak Inflow Estimation Method (May 2018)
- Application of Design Temporal Patterns on the Sunshine Coast (June 2018)
- Application of MIDIS for Rainfall on Grid Modelling on the Sunshine Coast (June 2019)
- Spreadsheet tool: DRAFT MIDIS (April 2019)
- Fact sheet: Rainfall on Grid Output Filtering (July 2019)
- Fact sheet: OSD Tank Orifice Plate Sizing (August 2018)
Review of Simple Peak Flow Estimation Methods
The Review of Simple Peak Flow Estimation Methods provides a:
- Regional Flood Frequency Estimation method and
- Modified Rational Method for use on the Sunshine Coast.
It has been the subject of an independent peer review. To review the application of the methods described in this report, use the spreadsheet tool.
Application of Design Temporal Patterns
This document considers the new ARR ensemble patterns. It gives a pragmatic interpretation of how you may use these, particularly with hydraulic models.
It has been the subject of an independent peer review. The spreadsheet tool will assist with the creation of MIDIS temporal patterns from Bureau Design Rainfall information and ensemble temporal patterns.
Application of MIDIS for Rainfall on Grid Modelling
This document addresses concerns of ARR Book 9 for Rainfall on Grid Modelling methods.
Rainfall on Grid Output Filtering
This fact sheet details the filtering methodology we'll adopt (as the default) for preparing overland flow mapping.
Fact sheet on OSD sizing
This fact sheet details the need for onsite water detention (OSD). It also provides a deemed to comply solution. The fact sheet on OSD sizing demonstrates how to apply the deemed to comply solution.
