THE Shaolin tourist and residential development at Comberton Grange will be an ecological disaster.
A water management report commissioned by the developer states their removal and retention standards to trap litter bigger than 5mm is 90 per cent.
This means 10 per cent of litter bigger than 5mm will go into Currambene Creek. For fine sediment, it’s 50 per cent. This means 50 per cent of soil – which is identified as having high erosion potential – can go into Currambene Creek.
For hydrocarbons, it’s 70 per cent, so 30 per cent into the creek. Phosphorus and nitrogen is 45 per cent, so a staggering 55 per cent will go into the creek. And this is with a 27-hole golf course and how many tonnes of fertiliser?
The report also states the development will require a sewage pumping station, which is not identified on the plan. Nor is the placement of the stormwater outlets that will pump all this crap into our pristine waterway.
In the same report the maximum rain event is 12 hours and there is no data on quantity of rain (mm per hour). The east coast low that hit the area in 2012 delivered 275mm over seven days and flooded parts of Nowra and Woollamia.
This is not good enough for our environment, the residents or the hundreds of thousands of people that flock to Jervis Bay every year. Algal blooms and silt will smother the fish nurseries that make Jervis Bay a recreational fisher’s dream. So all the fisherfolk will have to find somewhere else to go. This development must not be allowed to proceed.
