Kingsgrove residents living near a proposed bus depot in Vanessa Street are urging Hurstville Council to put the development application on hold until a proper solution can be found.
The application is expected to be discussed at the council meeting tomorrow.
Residents' spokesman Mark Shepherd said that if the present proposal went ahead, it would increase traffic problems greatly in an area already affected by congestion and would compromise the safety of residents, especially children.
Mr Shepherd said the depot should be discussed with RMS and Rockdale and Canterbury councils and a viable infrastructure solution found.
This could involve a new ramp access to the M5, behind the proposed depot.
The development proposal, deferred at the July 1 council meeting, seeks consent to turn 115 Vanessa Street into a transport depot for Transdev, with parking spaces for 60 buses and 52 cars.
The fitout of the existing warehouse buildings would include three workshop bays, a body shop, chassis and wash bays, an operations office and staff facilities.
A 60,000-litre capacity fuel tank would be on site.
The buses would be driven in and out between 5am and 11.30pm seven days a week.
Bus movements via King Georges Road would be restricted between 7am and 7pm to reduce the impact of noise on the residents in Vanessa Street and Tooronga Terrace.
Mr Shepherd said though residents appreciated the courtesy from the bus company and the council, restricting buses on King Georges Road would only transfer the traffic problem to Kingsgrove and Commercial roads, where major blockages would occur.
"That would stall the traffic back to Beverly Hills and make it much more difficult to get to the city," he said.
"Vanessa Street is already chock-a-block with cars and the road is narrow when fully parked out.
"If you add buses to this, you increase the danger of accidents."
Mr Shepherd said the area was under pressure already from sports groups that used the park and from the recently extended preschool.
Residents did not trust the bus company.
"They say they won't allow buses on King Georges Road but who is going to police it?" Mr Shepherd said.
Hurstville Council has received six submissions, including a petition with 46 signatures.
