Hewitts Creek Incorporating Slacky, Tramway, Woodlands & Thomas Gibson Creeks - Floodplain Risk Management Study & Plan

The catchments of Slacky, Tramway, Woodlands, Hewitts and Thomas Gibsons Creeks are located in the northern suburbs of the City of Wollongong. They are situated on a narrow strip of coastal land backed by the lllawarra Escarpment to the west and the coastline to the east. The combined creek system drains an area of some 7.5 square kilometres of mixed residential, retail, light industrial and forested land. Slacky Creek discharges to the ocean across Bulli Beach, south of Sanden Point. Tramway, Hewitts and Woodlands Creeks discharge to the ocean across McCauley's Beach, north of Sanden Point. Thomas Gibson Creek discharges to the ocean across Thirroul Beach, north of the Hewitts Creek outfall. The primary objectives of this study are:

  • To acquire and assemble data on flood behaviour, flood damages and properties in the catchment that are subject to periodic inundation.
  • Using the previously prepared hydrologic and hydraulic models from the Flood Study, develop and analyse various floodplain management measures
  • To examine existing flood planning policies and controls and recommend modifications to improve their efficacy.
  • In consultation with various stakeholders, develop a range of measures to reduce the impact of flooding risk and assess these measures on the basis of their measured performance against a range of economic, social and ecological objectives.
