Brown Hill, Keswick, Glen Osmond and Parklands Creeks are important drainage watercourses in metropolitan Adelaide. The creeks have a history of flooding and a low standard of flood protection, and therefore a relatively high flood risk. Their combined catchment is mainly contained within the local government areas of Adelaide, Burnside, Mitcham, Unley and West Torrens.

As a result of the Stormwater Management Agreement between the State Government and the Local Government Association and subsequent amended legislation (Schedule 1A of the Local Government Act), the catchment councils, in 2007, took over responsibility for implementing catchment-wide stormwater management measures.
The Brown Hill Keswick Creek (BHKC) Stormwater Project is a collaborative effort between the catchment councils of Adelaide, Burnside, Mitcham, Unley and West Torrens to mitigate serious flood risks and help safeguard properties across the catchment of Brown Hill and Keswick Creeks.
The project has developed a 2016 Stormwater Management Plan (2016 SMP) to substantially reduce the number of properties that would be affected by very large flood events along the four major watercourses of the catchment.
The 2016 SMP was submitted to the Stormwater Management Authority for approval in March 2016 and builds on the 2012 SMP (gazetted as the SMP in 2013).
It includes recommended flood mitigation infrastructure works in two categories, Part A Works and Part B Works, as follows:
- Part A Works: are designed to mitigate flooding generated from the mainly urban sub-catchments of lower Brown Hill Creek and Keswick, Glen Osmond and Parklands Creeks. These works, which comprise approximately 80% of the project, have already commenced.
- Part B Works: are designed to provide flood mitigation in the upper Brown Hill Creek catchment.
