Lower Brown Hill Creek extends from Anzac Highway to the confluence with Keswick Creek near the eastern boundary of Adelaide Airport. It is required to upgrade sections of lower Brown Hill Creek by up to double its existing capacity in order to accommodate existing peak stormwater flows from upper Brown Hill Creek together with flows to be diverted from Keswick Creek into lower Brown Hill Creek under the ‘Diversions’ project.

The proposal is outlined in Section 10.3 of the 2016 Stormwater Management Plan.
