The Brown Hill Keswick Creek (BHKC) Stormwater Project is a collaborative effort between the Cities of Adelaide, Burnside, Mitcham, Unley and West Torrens to mitigate significant flood risks and help safeguard properties across the catchment of Brown Hill and Keswick Creeks — which impacts each of the constituent councils.

From its inception in 2007 until February 2018, the project was conducted as a joint arrangement between the Constituent Councils. The Stormwater Management Plan was developed during this phase, leading to its subsequent approval by the Stormwater Management Authority and gazettal of its adoption in February 2017.

A condition of the Stormwater Management Authority approving the Plan was that a regional subsidiary be established within 12 months to implement the Plan and manage its works. The Brown Hill and Keswick Creeks Stormwater Board (the Board) was established in February 2018 as a regional subsidiary pursuant to section 43 of and schedule 2 to the Local Government Act 1999.

The Board is responsible for the administration of the affairs of the Regional Subsidiary and for ensuring ‘the Regional Subsidiary observes the objectives set out in the Charter, that information provided to the Constituent Councils is accurate and that Constituent Councils are kept informed of the solvency of the Regional Subsidiary as well as any material developments which may affect the operating capacity and financial affairs of the Regional Subsidiary’.

The Board is comprised of five independent members, appointed following recommendations made by a Nominations Committee of representatives from each of the Constituent Councils. Each Board member contributes a unique set of skills and experience, particularly covering:

  • Corporate financial management
  • Corporate governance
  • Project management
  • General management
  • Engineering
  • Economics
  • Environmental Management

Board members are appointed for a term of three years and are eligible for reappointment at the conclusion of their term.
