South Rockhampton Flood Levee

The South Rockhampton Flood Levee has been identified as the most cost effective option to mitigate the effects of flooding in Rockhampton. It was first identified in 1992, was further supported by updated modelling in 2011, and has been confirmed by rigorous analysis including updated flood modelling in 2014.

The flood levee has been described as a generational project which will paint a new future and brighter economy for Rockhampton. It will protect over 1,100 properties, keep the highway open, protect two schools and reduce the impact on the local economy.

Rockhampton Regional Council is currently finalising funding for the levee in partnership with the Federal and Queensland Governments.

Benefits of the South Rockhampton Flood Levee

A well planned, designed and maintained levee would deliver a wide range of benefits to Council and the wider community, as well as to those who live, work and do business in areas affected by flooding. This includes Gladstone Road, the lower CBD, Depot Hill, Port Curtis and Allenstown areas.

  • The levee will protect over 1,000 properties including dwellings, commercial properties and rural properties particularly in Gladstone Road, the lower CBD, Depot Hill, Port Curtis and Allenstown
  • Important community infrastructure will also be protected including the Depot Hill and Port Curtis State Schools, Rosel Park and the Rockhampton Pound
  • The levee will protect jobs by reducing flood damage to key commercial properties in the South Rockhampton area such as Hastings Deering who employ approximately 800 people and suffered more than $20 million in damages during the past two flood events
  • The levee will help protect the economy. The economic impact on Central and North Queensland of flooding on the Bruce Highway was estimated at $80.7 million dollars in 2011
  • Flooding costs us all money. In a period of 4 years alone, flooding across the Rockhampton Region has resulted in a repair bill of $67 million
  • The levee will also reduce the public health and safety risks associated with flooding including the protection of the South Rockhampton Sewage Treatment Plant
  • The levee will ensure access in and out of the city via the Bruce Highway during major flood events
  • May help decrease some home insurance premiums and
  • Provision of more useable land at Rosel Park and allow the development of fitness trails and heritage walks.

Council has engaged respected engineering consultants AECOM to undertake planning and design of the proposed levee. AECOM has assembled a team of expert engineers and scientists led by a specialist engineer with extensive experience in flood levee design and construction. The feasibility study covers a number of areas including:

  • Fitzroy River Flood Modelling
  • Local Drainage Inside the Levee
  • Geotechnical Investigations
  • Environmental Assessments
  • Civil Design and Ground Survey
  • The Business Case and
  • Community Consultation.
