Impacts of the Metro line on Dulwich Hill
The new Metro line from Sydenham to Bankstown (replacing the existing T3 Bankstown line) will have very significant noise, vibration and traffic impacts on Dulwich Hill.
The noise and vibration impacts are mainly caused by the fact that Dulwich Hill has so many dwellings close to the rail corridor. These dwellings will be severely affected by works to take place 24/7 over a period of five years.
The traffic impacts are largely caused by the need to use replacement buses for 100,000 commuters a day during proposed rail shutdown periods (during the July and Christmas school holidays between 2019 and 2024)
The Metro line is also being used an excuse to force dramatic overdevelopment in our corridor.
We have lodged a submission in response to the Metro EIS. You can read it here.
Below is a summary of the impacts:
A total of 1,221 properties will be exposed to noise at a level which breaches the potential for sleep disturbance criteria (background noise level plus 15 decibels from 10pm to 7am) during the construction period from 2019 to 2024.
This includes 783 properties which would experience noise from earthworks which exceeds the criteria for 30 weeks during the construction period.
Dulwich Hill is the worst affected suburb in the corridor for sleep disturbance in the Sydenham to Bankstown Corridor.

Some 74 properties, including 24 heritage properties in streets such as Wilga, Keys and Challis Avenues, would be put at risk of damage from excessive vibration levels caused by the use of intensive construction equipment.

Traffic and parking
New Canterbury Rd at Dulwich Hill will be packed with up to 1,020 buses a day during rail shutdown periods (eight weeks a year from 2019 to 2024 plus on an unspecified number of weekends).
Other streets with significant bus impacts include Marrickville Rd at Dulwich Hill shops (1,020 buses a day), Bayley St (495 buses), Beauchamp St (495 buses), Ewart St (495 buses).
A total of 27 commuter parking spots lost from the carpark to the south of the station, and nine out of the 17 parking spots in Bedford Crescent removed, during the construction period.
Up to 130 construction workers will want to park in local streets during rail shutdown periods, and up to 60 at other times.
During rail shutdown periods, even after mitigation measures, the average vehicle delay for the intersection of Wardell Rd and Ewart St will increase from 32 seconds to 55 seconds.
Residential streets such as Wilga, Keys, Challis Avenues and Albermarle, Beauchamp and Ewart Sts will be used as construction haulage routes.
Destruction of historic wooden railway station ticket office, which EIS reports state may be State significant.
