Cobra Street motorists will have noticed the wall that serves as a sound barrier and rear fence for vacant lots fronting Hindmarsh Esplanade in the Keswick Estate.

Its “modern” pattern is hard to miss. “It is intended to be visually interesting and draw the eye,” said a spokesman for Dubbo Regional Council, developer of the estate.

“The greyscale panels of different shades successfully breaks up the broad extent of the fence. The bright yellow highlights give the wall a positive effect. The pattern repeats every 10 bays.”

In building the wall, the council has sought to “do more than the minimum for residents and the public than providing a Colorbond fence”.

“Its purpose is to enhance the amenity, acoustic and private open space, of the lots within Keswick Estate stage 4,” the council spokesman said.

“It was also required to replace a vegetated earthen mound where an open storm water channel has now been constructed. The channel runs parallel to Cobra Street at the feet of the wall.”

The 315-metre long wall has 10-centimetre thick panels filled with sound-reducing polystyrene foam.

“All the panels are now in place and final finishes are still to be completed,” the council spokesman said.

“Substantial landscaping will be constructed forward of the fence for its full length and in between to enhance its presentation to Cobra Street.”

The wall will be extended along Cobra Street as the Keswick Estate grows.

“An acoustic wall to match this wall will be extended along the northern boundary of Keswick stage 5 release 1,” the council spokesman said.

“A gap of 80 metres will remain between the subject Keswick stage 4 wall and the next Keswick stage 5 wall to the east.

“The gap will be where the north/south stormwater channel currently runs, behind the Keswick Estate sales sign.” 

The council, which has declined to identify the cost of the wall, reports of a “few people” commenting on its pattern and bright yellow colour.

“The project is still in construction phase,” its spokesman said. “Significant landscaping will provide a positive visual impact along Cobra Street and the entrance to the city.”
