Council to replace pipes
Gosford Council will replace stormwater pipes in The Bartizan at Umina Beach that have caused surface cracking in the road's cul-de-sac.
According to a council staff report, The Bartizan at Umina Beach and the associated stormwater drainage system were constructed as part of the development of a private subdivision of this land in the late 1970s.
"The cul-de-sac section of this road has required regular heavy patching due to the poor condition of the pavement, recently confirmed to be caused by failure of a stormwater pipeline under the road," the report stated.
"The replacement of this pipeline is not part of council's adopted four-year works program.
"However, in the circumstances, it is recommended that repair work proceeds immediately."
The report stated that local residents had raised concerns regarding the poor condition of the pavement at the cul-desac end of the street.
"Investigations have revealed that the distress in the road pavement is due to the failure of twin stormwater pipelines underneath the road.
"Video footage of the stormwater pipeline has confirmed separation and movement of the butt joints in the pipeline.
'Road base material is being washed through these open joints and as a result subsidence and cracking of the road pavement has occurred."
"The most appropriate remediation strategy is considered to be the replacement of the existing butt jointed pipelines with the more securely jointed spigot and socket pipelines used by council for over two decades.
"There is a risk of major subsidence of the cul-de-sac and it is considered essential that works be undertaken to rectify the situation.
"The piped drainage system at The Bartizan, Umina Beach, will be replaced at an estimated cost of $150,000 as soon as it is practical to schedule the work."
