We are reducing the risk of flooding along Port and Woodville Roads through the $24million Port Road Drainage Project.
In collaboration with the Stormwater Management Authority (SMA), Charles Sturt will commence work in January 2017. The Project will ensure that in a 1 in 100 year rainfall event, the Queen Elizabeth Hospital emergency entrance will remain accessible.
Currently, during a 1 in 100 year rainfall event, the Port and Woodville Roads become inaccessible with knee deep (600mm) water preventing emergency services and the community from accessing TQEH. Over 3,800 homes would also be potentially flooded.
The Port Road Drainage Project will install underground drains in the Port Road central median between Old Port Road (Cheltenham) and Park Street South (Woodville) which will provide stormwater flood mitigation to suburbs of Albert Park, Cheltenham, Woodville West and Woodville in the Port Road stormwater catchment.
There are trees which will be removed from the median to make way for the underground drains. Independent and detailed investigation and planning was undertaken to minimise the impact to trees of the drains being installed into the median strip, however due to their large size and the existence of power lines, gas works, and underground infrastructure, we were unable to retain all of the trees.
Once the drains have been installed, Charles Sturt will spend $4.67m to landscape the median once again, planting mature trees, trees and shrubs, as well as creating irrigated grass areas. Charles Sturt remains committed to landscaping the Port Road median after the project to ensure our replacement planting creates an attractive and environmentally responsible area for decades to come. The artist impression above indicates how we will re landscape the median, providing grass and trees to ensure it looks attractive and represents a biodiverse space.
Like the Water Proofing the West - Stage 1 (WPW) Project, the Port Road Drainage Project will have long term benefits for the community in mitigating the risk of flooding to the area. Public information nights provided positive community feedback, with residents acknowledging that despite a loss of trees and a considerable mess for a period of time, similar to the WPW Project, the community has confidence the end result will be a good one.
The City of Charles Sturt has been working with the Department of Environment, Water and Natural Resources (DEWNR), the Adelaide and Mount Lofty Ranges Natural Resource Management Board (AMLRNRMB) and the Stormwater Management Authority (SMA) for several years to provide a sustainable, non-potable water supply and reduced flood risks within the City of Charles Sturt area. We were successful in obtaining funding from various sources of Local, State and Australian Government for the Water Proofing the West - Stage One (WPW) Project. This WPW Project which has both water re-use and flood mitigation components has now reached practical completion and the Project has gained awards for its innovation and multi-objective outcomes for the community. The Old Port Road works component of the WPW Project was the first stage of the flood mitigation works defined under the gazetted Stormwater Management Plan (SMP) for the Port Road stormwater catchment.
Water Proofing the West - Stage One Project has become a unique, integrated Water Sensitive Urban Design solution to the challenges associated with storm water management storm water quality improvement, flood management and water supply management in a fully developed urban environment.
The Port Road Drainage Project will prove to be just as exciting, providing a series of benefits for all local residents in the West.
Council in consultation with the SMA Board agreed to focus only on the stormwater drainage and flooding components and to extend the proposed staging of the Project works to a scope that includes the area from the intersection of Old Port and Port Roads to Park Street South (east of Woodville Road) with a Project cost estimated at $24 million.
The proposed scope of works is limited to upgrading stormwater drainage capacities. Reducing the scope to focus on drainage has meant the removal of the central median detention basins and streetscape works which meant that the proposed underground pipes could be re-aligned and in some areas placed next to each other to potentially save costs and preserve a number of existing trees in the Port Road central median.
The Port Road Drainage Project will involve substantial earthworks and construction activities on various roads, reserves and through the Grange railway.
