Pollard Park Waterway naturalisation
Alluvium transformed a degraded, actively eroding waterway in Pollard Park into a stabilised, ecologically rich and community-friendly corridor—blending natural channel design and water sensitive urban design to improve water quality, urban ecology, and recreational amenity in Ipswich City.

The waterway through Pollard Park in Camira was actively incising, with minimal ecological value, presenting challenges for both environmental and recreational use. Alluvium was tasked with stabilising the eroding waterway while improving water quality and enhancing the park’s recreational amenity.
Alluvium designed a channel stabilisation plan aimed at halting the active erosion and improving water quality. The solution included both hard and soft engineering features, such as pool riffle sequences, which replicate natural processes to stabilise the channel. The design incorporates water sensitive urban design elements that work with the park setting to improve water quality while promoting the social and recreational values of the park.
The project significantly enhanced urban ecology and liveability in Ipswich City. Native plants and animals thrive in the restored waterway and riparian habitats, providing a richer environment. The new riparian corridor also contributes to urban cooling and carbon capture, while reducing flood impacts and creating a high-quality open space for the community.
