Central Geelong is located on the flow path of a historic creek and at the bottom of several catchment areas that drain to Corio Bay. Johnstone Park has an important drainage function as a major retarding basin, capturing water from Geelong West and Newtown. In a significant storm event, flooding occurs across some parts of the city. Fast flowing and deep water causes safety issues in some locations, while other impacts include damage to private property.
The design of streets and new infrastructure upgrades can reduce the impact of significant storm events, as well as enabling better development outcomes.
The Central Geelong Drainage/Flood study investigates a series of capital works projects to test what benefits could be achieved throughout the city. Options include improved drainage infrastructure, safety initiatives and water sensitive urban design opportunities, which will inform future capital works within the City.
Key projects are:
Johnstone Park including outfall pipe, with a new main drain proposed down Gheringhap Street
Eastern Beach Road floodway
Little Malop Street localised flooding improvements (west of Fenwick)
installation of safety and flood warning signage at the Gordon Avenue and Brougham Street underpasses.
To implement these projects, further scoping is now underway.
Water Technology undertook the study, having completed significant previous work for regional CBD’s including Ballarat, Bendigo, Werribee and Warragul and also Melbourne’s Elizabeth Street, which runs along a former creek.
Following the storm on 27 January 2016, Water Technology are undertaking a review of the rain event that occurred, including assessment of the impacts of implementing key projects identified in the Drainage / Flood Study.
