Alfredton residents turned out in full force at a Ballarat City Council meeting on Wednesday evening.

They implored councillors to reject an application to subdivide and build a dwelling at the rear of an existing three bedroom dwelling at 3 Lyndon Court.

The proposed block of land is 972 square metres in size and irregular in shape.

Multiple longstanding residents said the development would destroy the “close-knit community and family character” of the court and argued it was an over-development of the site.

Trudy Murnane, who has lived in the court for 36 years, said the development threatened the “family values and integrity” of the court.

She said the neighbourhood prided itself on being a safe place for children to play, but the additional dwelling, could bring an influx of traffic endangering the lives of children.

“It could fracture everything our court community has set up,” she said. 

Cr Des Hudson said while he sympathised with residents’ “fear of the unknown" and their strong connection to the street, the development was in-line with the city’s planning scheme.

He said if the application was challenged by another planning body outside of the council, like the Victorian Civil Administrative Tribunal, there wouldn't be sufficient evidence to mount a case.

Councillors Belinda Coates, Mark Harris, Ben Taylor also voted in favour of the development.

But Councillor Daniel Moloney said the application was “grossly inappropriate” and would be “crammed up” against the neighbouring house.

Councillors Grant Tillett, Jim Rinaldi and Samantha McIntosh also voted against the project. 

Cr McIntosh had the deciding vote as mayor.
