Port Road Drainage Project

See the whole story: here

The Port Road Drainage Project is designed to help reduce the risk of flooding on Port Road.

We are now at Stage 3 of the project. This stage works on the median strip and runs between Park Street South to Minnie Street. This part of the project extends on the work done in previous stages.

Funding for the project

  • $8.2 million is secured through the Stormwater Management Authority
  • $16.3 million is funded through the City of Charles Sturt's Long Term Financial Plan

Stage 3 of the project includes:

  • a 2.3km drainage upgrade
  • an underground detention tank to decrease flooding
  • the extension of our recycled water network
  • upgrading of existing carparking
  • self-watering tree pits
  • parking spaces that are compliant with the Disability Discrimination Act
  • extension of shared used pathways
  • lighting to both carparks and the shared use path

Benefits of Stage 3 will be: 

  • access to the QEH Emergency even in time of significant storm events
  • reduced flood risk for private and business properties along Port Road
  • reduced frequency of water flooding the Port Road carriageways during storm events
  • re-landscaped Port Road median with turf, trees and shrubs to improve the amenity of the area, with upgraded carparks and shared use path

Project background

The project started in April 2019 and is expected to be complete in December 2020. It's a collaboration between the City of Charles Sturt and the Stormwater Management Authority (SMA).

Stage 3 of the project ensures that in a 1 in 100 year rainfall event, the Queen Elizabeth Hospital emergency entrance is still accessible.

The previous project stage included installation of underground drains in the Port Road central median between Old Port Road (CHeltenham) and Park Street South (Woodville). This helps to reduce the risk of stormwater flooding to suburbs of Albert Park, Cheltenham, Woodville West and Woodville.

Once the drains were installed, we planted mature trees and shrubs and irrigated grass areas. With this replacement planting, we aimed to create an attractive and environmentally responsible area for decades to come.

The Port Road Drainage (PRD) Project will have long term benefits to the community, and mitigate the risk of flooding to the area. The Water Proofing the West project has similar outcomes.

Like the Water Proofing the West - Stage 1 (WPW) Project, the Port Road Drainage Project (Stage 2 – complete and Stage 3) will have long term benefits for the community in mitigating the risk of flooding to the area.

We've been working to provide a sustainable, non-drinkable water supply and reduce flood risks within the City of Charles Sturt.

This work as been over several years 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).

As with PRD Stage 2, the removal of some existing vegetation is required. Stage 3 will see the removal of 52 regulated or significant trees, as well as a number of smaller trees, bushes and shrubs.

After the drainage installation, and as part of the landscaping works, more than 450 trees, 7,300 plants and nearly 60,000m2 turf together with associated irrigation will be installed, completing the upgraded median from Old Port Road through to King Street.
