Cobblers Run Residential Subdivision - Figtree, NSW

Cobblers Run Estate is the 4 th stage of a DA-approved 22 lot subdivision in Figtree, NSW. The site was vacant land, and has been vacant since the development consent was obtained from WCC in 1992. Our client engaged Rienco Consulting to prepare a suitably detailed flood study that addressed the requirements of Wollongong City Council’s (WCC’s) DCP Chapter E13, to enable the Construction and Subdivision Certificates to be issued.

This study was complex, because Council’s adopted catchment-wide Allans Creek Flood Study has a series of known errors that meant design flood behaviour within Figtree was not properly quantified. Moreover, Council has updated its blockage policy since the Allans Creek Flood Study was completed in 2008, which dramatically changes design flood behaviour again. Neither fixing the known errors nor the updated hydraulic modeling had yet been completed by Council.

Rienco developed hydrologic (WBNM) and hydraulic (TUFLOW) models to quantify design flood behaviour at the site. Both Rienco’s hydrologic and hydraulic model was peer reviewed by WMA Water, who concluded that the modelling provided for Cobblers Run Estate was ‘industry best practice’.

The subdivision is now constructed, and being developed by the purchasers of each lot.

What our customers say


In my capacity as an architect I have worked with Anthony on a large number of projects throughout the Wollongong area. Anthony has a deep knowledge of local stormwater issues, and in particular the risks and mitigation strategies that should be applied. He is very experienced in the requirements of local councils and has contributed to many successful applications of all scales, from renovations to developments and subdivisions. I can wholeheartedly recommend Anthony and the Rienco team for their practical and professional approach to assessing and solving stormwater related conditions, and as effective advocates in dealing with the council planning controls.

I use Rienco for all flooding and drainage matters on my projects because of their flooding modelling skills and pragmatic understanding of the difficulties of land development. The top-line integrity of their work was demonstrated recently on a very contentious project where the Rienco report passed a rigorous peer review by one of Australia's leading hydrology firms, with no change to the original findings and recommendations. It's comforting to know with Rienco you have that clarity of thinking helping find the best solution, and the confidence that it will be right.
