THE Tumby Bay District Council has had to increase its budget for the Graham Smelt Causeway culvert to complete an environmental assessment.
After a structural assessment in the 2015/16 financial year, the council decided to start planning to replace the culvert within the next few years.
We are planning for the renewal of the structure when its life is up.
At the Tumby Bay Council meeting on Tuesday works manager Damian Windsor said there were early discussions with the Department of Environment, Water and Natural Resources.
“If council wanted to do anything less than a complete replacement and upgrade we need to do an environmental assessment to ensure there’s no environmental degradation,” he said.
The 2016/17 budget includes funding for concept design work for the culvert plan.
At the meeting the council moved to endorse extra expenditure of up to $15,000 to complete the environmental assessments required for the concept design.
Mr Windsor said the environmental assessment was an extra component to make sure the work took place.
“We are planning for the renewal of the structure when its life is up,” Mr Windsor said.
