Consultation has concluded

With guidance from the City’s Environmental Plan 2019 to 2023 the City is proposing to install a living stream in the drain outlet at Cliff Sadlier Reserve to improve the function and appearance of the existing drain. The drain outlet is the property of Water Corporation and the Reserve is maintained by the City. The project will be delivered by the City of Subiaco in partnership with Water Corporation, aiming at integrating stormwater into open space areas.

Project update - September 2020

Work commenced August 2020. Please see photo library for photos of the work, or visit the reserve to have a look.

The following were planted:

Anigozanthos flavidus Red
Anigozanthos humilis
Banksia ashbyi Dwarf
Baumea preissii
Beaufortia elegans
Conostylis aculeate
Conostylis candicans
Dianella revolute
Ficinia nodosa
Grevillea obtusifolia Gingin Gem
Grevillea preissii Sea Spray
Hypocalymma angustifolium
Juncus kraussii
Juncus subsecundus
Leucophyta brownie
Melaleuca preissiana
Melaleuca viminea
Patersonia occidentalis
Pultenaea reticulate
Scaevola anchusifolia
Verticordia plumosa





Note: the conservation fence around the planting area is to protect the newly planted seedlings from pedestrian and animal traffic. The plants will be monitored over the coming months and the fence will be removed once the plants are established.


Living streams provide the following benefits:

  • flood control and conveyance
  • erosion and sediment control
  • establishment of healthy ecosystems
  • creating diverse habitat
  • improving water quality
  • enhancing amenity of the area
  • increasing environmental awareness
  • removal of pollutants and
  • improvement of the parks aesthetics.

The work

The project will allow for part of the drain system to be converted to a living stream.

Three sites have been identified that have the worst erosion issues, and will be undertaken as a priority:

  • The first site is situated at the eastern drain outlet - completed in August 2020
  • The second site is at the central bridge
  • And the third site is located downstream (before the western drain outlet).

Coir matting will be installed on either sides of the banks to help to combat erosion and the whole drain system will be planted with aquatic and semi-aquatic native plant species. A conservation fence will be installed around the planting area to protect the newly planted seedlings from pedestrian and animal traffic. The fence will be removed once the plants are established.

It is anticipated that the first and second sites will be installed in late August 2020. The third site will be planted following a brief establishment period and further planting will then be undertaken to link the sites.

Consultation outcome

Between 11 May and 12 June 2020 the community were asked for their feedback about the City’s proposal to install a living stream in the drain outlet at Cliff Sadlier Reserve. A total of 19 people provided feedback with a 74% positive result. For the full report, including the City's responses to comments, concerns and suggestions please see the Consultation Summary Report in the document library. The living stream project will now proceed (project commencement in mid-August 2020).
