The plan, on exhibition at Wollongong City Council, is to develop the old Greens Northern Coaches bus depot on Hewitts Ave into three duplex buildings.

The bus depot contains two industrial sheds which would be demolished under the plans, lodged by Thirroul development firm Develop My Land, on behalf of a company called Hewitts Avenue Pty Ltd.

"The site is currently a disused bus depot which had been in operation on the site for over 60 years," the application states. "The continued industrial use on the site would not be supported by council within the R2 Low Density Residential Zone.

"The site is more ideally suited for residential use. The proposed residential dual occupancy will remove the out of character industrial sheds and replace with architecturally designed residences consistent with recent development."

The plan would include parking for twelve cars.

Contaminated soil from previous usage would need remediation.

A flood study included says the property is regarded as medium flood risk, and while the site would be inundated in a maximum flood event, the first floor areas would be untouched.

It says the development would " significantly improve" the flood affectation of many properties nearby.

Development control rules require any walls more than 7m in height must be set back at least 3m from the side and rear boundaries. The application wants a variation to this rule, saying that because flood controls dictate a floor level at least 900mm above ground some 7m walls would be set back 1.6m instead.
