Glen Osmond Creek Fern Avenue, Fullarton Bridge upgrade. Torrens Avenue, Fullarton Bridge upgrade. Minor upgrades along Glen Osmond Creek between Braeside Avenue and Burnham Avenue.
4. For each project completed so far how much has the risk of flooding in Unley reduced?
It is not possible to quantify the exact extent of reduction in flood risk, however, in the proximity of each project and immediately downstream there is a significant reduction in flood potential. The projects completed and soon to be completed in the next few years have/will greatly reduce the risk of flooding along Glen Osmond Creek, Parklands Creek and, to some extent, Keswick Creek. The minor projects that have been completed along Brown Hill Creek have had little impact on flood reduction accept in the local area of the works.
5. At what point will the risk have been reduced to an acceptable level?
The widely accepted stormwater industry standard for flood protection is 100yr ARI (Average Recurrence Interval) or 1% AEP (Annual Exceedance Probability). This standard is what has been assumed in the BHKC SMP. The project is scheduled to be completed over 20 years and therefore the modelled 100yr ARI flood protection will not occur until all projects are completed. Within the City of Unley – the Creek widening and bridge replacement between Victoria Street and Cross Road (Area 2 ‐ Area 4 including Orphanage Park) and Glen Osmond Creek minor upgrades are the last projects scheduled and are proposed to be completed in year 20, 2035/36.

King William Road will be closed to traffic for the next 4 weeks as Council takes a major step forward in getting the roadway paved. Businesses have now been asked to park their cars in the car park on Arthur St (Plymouth Brethren site). Council has introduced some goodwill initiatives to continue to support business. It was also good to see a couple of new shops preparing to trade in the near future. The initiatives include:
