TOWRADGI CREEK FLOOD STUDY December 2019

Towradgi Creek is located within the Wollongong City Council Local Government Area (LGA) and the 7.5km2 catchment incorporates the northern Wollongong suburbs of Tarrawanna, Corrimal, East Corrimal and Towradgi. The catchment extends from the Illawarra Escarpment in the west, discharging at Corrimal Beach in the east.

Towradgi Creek has a number of smaller tributaries, including: • South Angels Creek; • North Angels Creek; • South Corrimal Creek; • North Corrimal Creek; • Carr Creek (sometimes locally known as Jones Creek); and, • Parker Creek.

Following the completion of the 2015 Flood Study Review, Council developed a revised Conduit Blockage Policy in 2016. The 2015 Flood Study Review was based on Council’s previous Conduit Blockage Policy (2002) as documented in Council’s 2009 Development Control Plan.

This report provides an addendum to the 2015 Flood Study Review and outlines the revised design flood behaviour considering Council’s Revised blockage policy, in addition to catchment changes since 2015 and recommendations coming out of review of the models.
