ICOLL Catchments Flash Flood Warning System Scoping Study

About the project

The three catchment areas are Burrill Lake, Lake Conjola and Tabourie Lake. These catchments are characterised by being exposed to flash flooding and comprising ICOLLs with existing low-lying historic development adjacent to these coastal lakes.

Measures to improve flood warning and response through the implementation of a TFWS were recommended in the individual catchments' Floodplain Risk Management Study and Plans (FRMS&P) to reduce flood impacts and the risk to life within these catchments. This project will be undertaken in accordance with the NSW Flood Prone Land Policy, the NSW Floodplain Development Manual (2005) and in close collaboration with the NSW State Emergency Services (SES), the NSW Department of Planning and Environment (DPE), and other agencies and stakeholders.

Council has engaged a contractor, Manly Hydraulics Laboratory (MHL), to assist with the preparation of the ICOLL Catchments Flash Flood Warning System Scoping Study.
