Lauraine Drive public open space


Project Details

This site manages rainfall from small and large events before entering Balannup Drain. It is also creates an interactive public open space incorporating existing natural bushland.

WSUD Category: Detention Basin, Living stream, Retention of native vegetation, Swale / buffer strip

Criteria Information
Development Type:Public Open Space
Function/Driver:Water quality
Government Area:City of Armadale
Site Context:Shallow groundwater
Year Completed:2005

Lauraine Drive public open space (POS) in Vertu Estate is characterised by the Balannup Drain which runs through its centre. Stormwater from the street network is treated in a bioretention basin in Stills Avenue, before flowing into the POS. Flush kerbing along Lauraine Drive allows local runoff from rainfall events to be infiltrated within the grassed swales and vegetated areas of the POS, and thus close to source. Major events will overflow to the drain, after being detained by a series of constricting culverts. The retention of native vegetation and the planting of additional native vegetation provides a nutrient stripping function to the drain. Soft edge treatment of the drain west of Wright Road is preferred to the walled treatment east of Wright Road; however, the lack of grade across this area is noted as providing challenging conditions.

Shallow groundwater is also controlled in the area through subsoil drainage.

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