Water Sensitive Urban Design
The implementation of Water Sensitive Urban design (WSUD) has been identified as an important step in protecting aquatic ecosystems in the Townsville region from the impacts of development.
Preparation of Development Application
Prepare a stormwater management plan
The stormwater management plan must demonstrate how the water sensitive urban design stormwater quality objectives (pollutant load reduction targets) will be met. It should include stormwater quality modelling results to demonstrate compliance with the pollutant load reduction targets and identify the location, size and configuration of stormwater treatment measures and/or treatment trains proposed for the development.
Conceptual designs of the treatment measures should be prepared including a layout- plan, sub catchment boundaries and generic cross sections. Collaborate with landscape architects, urban planners and civil engineers to ensure the stormwater treatment measures integrate with the surrounding built and natural environment.
- Design Objectives for Stormwater Management (PDF, 380.8 KB)
The ‘Coastal Dry Tropics Water Sensitive Urban Design - Technical Design Guidelines’ describe appropriate methods for the detailed design of structural stormwater management measures in the Coastal Dry Tropics. The guidelines are intended as a detailed design tool, applicable in the mid to latter stages of the urban development process (i.e. preparation of operational works applications including monitoring and maintenance schedules).
The guidelines are based on the Healthy Waterways Partnership WSUD Technical Design Guidelines for South East Queensland (v1, June 2006), however, the chapters and worked examples have been specifically rewritten to address the particular adaptations required for effective operation in the Coastal Dry Tropics climate. The guidelines identify the appropriate design flows for use in sizing stormwater management measures (e.g. sediment basins and swales), design adaptations for constructed wetlands and bio retention systems required in response to the seasonal rainfall patterns and any other requirements to sustain vegetation and to meet best practice stormwater treatment objectives.
A series of 7 fact sheets have been developed to provide general advice on key considerations for the application of WSUD in the Townsville Coastal Dry Tropics. The fact sheets will assist in concept planning and preliminary lot layout and in the early planning stages of preparing a Material Change of Use (MCU) or a Reconfiguration of Lot (ROL) application. The fact sheets will benefit planners, urban designers, landscape architects, civil and landscape contractors, asset managers and can also be used for general communication and education purposes.
WSUD Concepts and Terminology (PDF 195.5 KB)

It includes an overview on the techniques and principles of applying WSUD; an outline of the benefits and an explanation of how constructed wetlands and bioretention systems can be applied to achieve best practice stormwater treatment.
Site Planning & Urban Design (PDF 908.6 KB)
Provides advice on developing an integrated and collaborative approach to applying WSUD in the Townsville Coastal Dry Tropics Region. It includes an outline of key considerations and processes required during site planning and conceptual design to successfully integrate WSUD principals and practices with the urban form. This fact sheet is intended to guide the establishment of a collaborative design team and gives guidance on how to apply WSUD principles to a range of site conditions.
WSUD in Industrial and Commercial Sites (PDF 1.2 MB)
