Bondi Junction raingarden

WaterWe are currently constructing 3 bioretention gardens (raingardens) in the Bondi Junction commercial area which will drain into Centennial Parklands.

The new raingardens form part of important environmental and streetscape improvement works. One has been built on the corner of Hollywood Ave and Ebley St, while two others are currently under construction on the northern and southern corners of the intersection of Gray St and Bronte Rd.

The gardens will help green-up the precinct and improve water quality and the ecological value of the Centennial Park Pond system.

This Water Sensitive Urban Design (WSUD) project is funded as part of the Botany Bay & Catchment Water Quality Improvement Plan.

What is bioretention and raingardens?

Bioretention gardens, also known as raingardens, are carefully designed with vegetation, soil, and types of treatment to remove pollutants from stormwater before it enters our beaches and waterways.

Bioretention uses Water Sensitive Urban Design (WSUD) to treat stormwater in public places for improved water quality.

How does it work?

Bioretention gardens look similar to a regular garden bed, but are designed specifically to capture stormwater from hard surfaces such as roads, driveways, patios and roofs via downpipes after it rains.

Beneath the garden are layers of sandy soil which remove pollutants such as nitrogen, phosphorus and fertilisers, which are washed off these hard surfaces.

What are the benefits of raingardens?

Key benefits of the raingarden projects include:

  • polluted stormwater will be filtered, improving the water quality of the ponds in Centennial Park which will in turn help to protect the ecology of the parklands
  • the gardens will provide an urban oasis which reduce urban heat and make for a more vibrant and natural streetscape
  • the construction of a new footpath for safer pedestrian access along Hollywood Ave
  • new informal public seating near the bus stop on Bronte Rd
  • the planting of over 180 new plants for a greener streetscape in Bondi Junction
  • the gardens are self-watering, requiring little maintenance
  • they will provide a healthy habitat for native wildlife.

When will works be completed?

Construction works on the Hollywood Ave raingarden are now complete, and final planting is underway. The two raingardens in Bondi Junction are under construction and are expected to be completed by the end of July 2014.
