West Yamba subdivision questioned


Clarence valley residents and the environmental group Valley Watch continue to ring alarm bells in relation to a proposed subdivision in West Yamba.

Today's Daily Examiner reports: Valley Watch member Ros Woodward said she was disappointed to see the development go through without proper consideration for the sensitive natural environment around it.

"West Yamba could be an example to the world of how to develop sustainably with a small footprint in a very sensitive area, but I am afraid all they can envisage is slab houses on great big mounds," Ms Woodward said.

A submission [to Clarence Valley Council] from Valley Watch raised concerns about how sewage would be dealt with in the development and how practical the filling solution was in the area.

Also in the Examiner is a letter to the editor addressing the issue:

DA concern

It is with a sense of foreboding that I notice that once again council will consider on Tuesday a subdivision on Carrs Drive, West Yamba. This time the proposal is for 15 lots instead of 22, but fundamental problems of sewerage, fill and truck movements remain.

Since Maclean Shire Council endorsed in November 2003 the recommendations of the Yamba Wastewater Management Strategy, the community has been told regularly that development of West Yamba will not go ahead until the sewage treatment works are upgraded. One reason for this was that dual reticulation - a key element of the strategy - was only feasible on a greenfield site. Now we learn that on-site wastewater systems (that is, septic tanks) are proposed for the subdivision in spite of the Zone 1(y) objective that the land be connected to reticulated sewerage. Onsite sewage treatment in a flood-prone area is a major concern, but of even greater concern is the likelihood that this subdivision will make dual reticulation difficult or impossible for the future.

Dual reticulation (that is, use of high quality recycled water for toilet flushing, garden watering and car washing) will substantially reduce the amount of drinking-quality water being used - an important consideration given Yamba's growing population and an increasing risk of below average rainfall, higher temperatures and evaporation, and below average runoff, according to the CSIRO. Its implementation cannot be put at risk by a 15-lot subdivision.

Then there is the matter of the fill necessary for the site. There are 15 lots in this proposal, but the Flood Plain Risk Management Plan recommends that key services remain operable during times of flood up to at least the 100 year +0.5m level - that is 3.24 metres AHD. The height of land in West Yamba at present is between 1.0 metres and 1.5 metres. To fill it to 3.24 m AHD to allow key services to remain operable will take over 12,000 twenty-tonne truckloads a year for about nine years. (Yamba Floodplain Risk Management Study, Webb, McKeown and Associates Pty Ltd, July 2008)

One has to ask what the impact of this traffic will be on our roads and bridges. A twenty-tonne truck crossing Shallow Channel every six minutes is a scary thought!

If Yamba wants to remain a desirable tourist destination it cannot afford to have its one road in and out of town clogged with trucks.
