Urban Subdivision - Worrigee NSW

Our client proposed to subdivide the majority of their R2 zoned land into 154 large residential lots, ranging from around 0.25 ha to 1.44 ha.

The site is a former golf course and contains areas below mean sea level.

The site is affected by complex flood behaviour from the longer duration Lower Shoalhaven River, as well as shorter duration local catchment flooding (Rotten Creek).

Rienco was engaged to carry out a complete Integrated Water Cycle Management Study, comprising a detailed 2D flood study and the preparation of concept WSUD measures.

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.
