DesignFlow used multi-criteria analysis to identify, assess, and prioritise stormwater treatment retrofit opportunities for Bells Creek in Redcliffe, and then developed detailed designs for two priority sites.

The first site, which is now complete, treats 70 hectares of existing urban areas and incorporates anew open water body that draws off water to a bioretention basin within an existing park area. The designs were mindful of existing park use and accommodate existing trees.
