Panther Elbow public open space & tree pits


Project Details

Detention of stormwater to achieve flood protection objectives. Useable public open space providing an appropriate connection to the Bush Forever site

WSUD Category: Swale / buffer strip, Tree pits

Criteria Information
Development Type:Public Open Space
Government Area:City of Gosnells
Site Context:Shallow groundwater
Year Completed:2011

Panther Elbow is a local street within the Bletchley Park Estate which borders a Bush Forever site and conservation category wetland, Balannup Lake. It also borders a passive public open space (POS) area which incorporates existing mature native vegetation and provides flood detention for runoff generated during major rainfall events. Underground storage cells have also been installed on the border of the POS area to infiltrate road runoff generated from the 1 year ARI event at source, and maintain local hydrological conditions. Underground cells are connected to the major POS detention area via a bubble up pit. Tree pits are also located within Panther Elbow and connecting streets and are designed to treat the first 5 mm of stormwater runoff generated from rain events.

Overall, the POS has been developed to maximise amenity for local residents, provide a drainage function, and create a connection with surrounding natural bushland and wetlands.

This site was part of the WSUD Tour through the Cities of Gosnells and Armadale. The whole document can be downloaded here.
