Water sensitive urban design (WSUD) standard drawings

Our water sensitive urban design (WSUD) standard drawings outline the design and construction requirements for bioretention systems (a.k.a raingardens, biofilters), swales, porous paving, street tree pits, rainwater tanks and on-site stormwater detention systems. 

The drawings are intended to be used in conjunction with the small scale stormwater quality model S3QM tool. The drawings provide complying solutions, however, they should not stifle innovation or replace sound engineering judgement.

The drawings may require modification to suit local topography, soils, landscape, services and site conditions.  They specify the requirements for bioretention filter media, hydraulic testing, liners, gross pollutant traps, vegetation, shading and mulching.  They also outline the construction inspection hold points and requirements for establishment and staging of works.

Review of WSUD standard drawings

We are currently reviewing the WSUD standard drawings. This review includes the following:

Interim changes

We have made some interim changes to the WSUD standard drawings (Revision D) by providing additional information on sheet 3, 4 and 11. These changes are to improve aesthetics, community access and usability of the parkland.

Further detail about these changes are incorporated in the Landscape design principles for SP2 land document that can be found here.

Detailed review

We are undertaking a detailed review of the WSUD standard drawings that is expected to be completed early in 2023.
