Cooby Road Rezone - Tullimbar, NSW

Our client sough to prepare a Planning Proposal to rezone land at Cooby Road, Tullimbar for the purposes of residential subdivision and development. The site is flood affected and our client engaged Rienco to prepare a suitably detailed flood study that addressed the requirements of the NSW Planning Minister’s Section 117 Directions.

Rienco developed hydrologic (WBNM) and hydraulic (TUFLOW) models to quantify design flood behaviour at the site. We also integrated our solutions with the urban design team to ensure creek and overland flows could be managed through future open space and waterway crossings.

The project is progressing through the Planning Proposal process.

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.
