HYDRODYNAMIC estuary modelling will need to be funded, tested and reviewed before the next steps are taken to widen or replace Kenwood Drive bridge at Lake Cathie.
Port Macquarie-Hastings Council will recommend at its October meeting on Wednesday (October 21) that a review of the 2011 Lake Cathie-Lake Innes Estuary Hydrodynamic Model should be undertaken as a part of stage two of its Coastal Management Plan (CMP).
Council is developing its CMP which is a framework for the long-term strategic and integrated management of priority coastal hazards, issues and risks to the Port Macquarie-Hastings coastal zone, in line with the community's needs, NSW state objectives and legislation under the Coastal Management Act 2016.
Council will consider the process, time frame and costs associated with reviewing the 2011 Lake Cathie/Lake Innes hydrodynamic report which can't be undertaken until the model has been reviewed and tested.
Council has requested concept designs be developed for Kenwood Drive Bridge at Lake Cathie.
Community groups Revive Lake Cathie and Saving Lake Cathie have lobbied the council to widen Kenwood Drive bridge to improve tidal flows in the lake and believe the action is central to ensuring better long-term water quality.
Kenwood Drive bridge was built in the 1970s.
It ranks 86th of the 140 bridges in the local government area in terms of condition.
The average costs of a bridge concept design, including geotechnical investigations and a detailed site survey, are about $100,000.
The meeting starts at 5.30pm and can be viewed via council's YouTube channel.
