Scope
Modelling, planning and design to investigate the impact a transition of rural residential land into urban residential land will have on surface water within and beyond the Marshall Precinct
Impact
Finalised drainage strategy considering a range of aspects and constraints

WMS delivered a drainage strategy for the Marshall Precinct Structure Plan in Greater Geelong in 2019. This project was delivered in partnership with the City of Greater Geelong and Alluvium. The Marshall Precinct is located within the City of Greater Geelong (CoGG), approximately 8 km south of the Geelong Central Business District (CBD).

This Stormwater Management Strategy (SWMS) was prepared to inform the development of the Marshall Precinct Structure Plan (PSP). The primary aim of the SWMS is to investigate the impact that the transition from rural residential land uses into predominantly urban, residential development will have on surface water within and beyond the PSP boundary. The study involved complex hydrological and hydraulic modelling using an ensemble approach which was then used to assess a range of surface water mitigation options for the site. 

The project outcome was a delivered drainage strategy considering existing topography and drainage alignments and assets, the proposed urban layout and upstream and downstream constraints
