Our Health and Environment

Building these tunnels will have a devastating impact on the lower north shore.  Waverton, North Sydney, Cammeray, Naremburn, Artarmon, Northbridge and Willoughby will feel all the pain with no gain.

 

To make the tunnels stop, the best thing you can do is lobby our decision makers and inform others so they can do the same.  You can write, petition, visit, share and participate in many different ways. Click the button below for help doing this : it only takes 10 minutes but could make a world of difference

What's  happening?

The tunnel projects will result in noise, water, land and air pollution - based on expert examination of the 9000+ Paged Environmental Impact Assessment (WHTWFU Jan 2020) and the latest Beaches Link and Gore Hill reference design (RMS, July 2018) and the scope reports (RMS, October 2017).  

There will be a significant loss of green space – this is already at a premium. Native wildlife will be under threat.
No spotlight is on our area – RMS has paid little attention to the environmental impact on Flat Rock Gully Creek, Flat Rock Gully and Tunks Park.

Here's what you need to know

Polluting our community’s favourite recreational areas

  • Flat Rock Gully Creek flows from Artarmon Reserve, through Flat Rock Gully and down into Tunks Park – this water course is part of a wildlife protection area. Given the proximity of the planned construction site at either the Baseball Diamond or Flat Rock Drive and typical run-off flows, it is highly likely that Flat Rock Creek will be polluted.

  • Northbridge Baths would likely be unusable for the period of the project and for some time after. Dredging the harbour floor will harm marine life and make a large portion of Middle Harbour waterways unusable.


Flat Rock Tip Site – the preferred tunnel route goes through an old tip and landfill site.

  • The proposed route will cut through an old tip site. This puts residents and the environment at risk from surface & ground water contamination - this comes from disturbing landfill materials, such as asbestos and toxic chemicals either on the surface or below ground.


Damage to native fauna and flora – a fragile ecosystem

  • Flat Rock has been extensively rehabilitated since its time as a tip in the 1980s. It boasts many species of native flora and fauna – pollution and disturbance will impact this fragile ecosystem which has taken decades of community and council work to recover.


Air pollution

  • Fine dust particles entering the air in and around construction sites (Flat Rock Baseball Diamond/Drive and Cammeray Gold Course) and transport corridors (Brook St and Flat Rock Drive) pose a potentially serious risk to human health and the environment. The World Health Organisation classify silica dust from sandstone and granite processing as carcinogenic. Homes around the construction sites and transport corridors could easily be contaminated by dust (this has been reported in other areas), sporting teams playing adjacent may breathe it in and local school communities may come into contact.

  • Smoke stacks are a huge concern with several stacks needed to service the tunnels across a predominantly residential area. Unfiltered stacks simply extract, condense and then disperse road pollution across an environment.  Adding more stacks to an area with many schools, pre-schools and hospitals on the Lower North Shore is a major concern.


Noise pollution – non-stop for at least five years

  • Trucks, drilling, ground work and preparation activities mean noise along and around the construction corridor. Construction noise will be 24 hours/7 days. This will impact residents, students and local businesses. Noise pollution affects sleep, concentration, stress levels and health.


Loss of green space - community recreation and local sport will suffer

  • Flat Rock Baseball Diamond and a substantial section of Cammeray Golf Course will be out-of-bounds if they become construction sites. Tunks Park may be contaminated due to run off from Flat Rock Creek.  

  • Bicentennial Reserve (sealed courts and fields), Cammeray tennis courts, Cammeray Park football pitch and the skate park may not be safe to use due to noise and air pollution.

A detailed analysis of the Western Harbour Tunnel and Warringah Freeway Environmental Impact Statement/ Plans can be found on the final plans page under "Our Analysis". Further summaries will be added to this page once the Beaches Link Environmental Impact Assessment becomes available in the 3rd quarter of 2020. Information has been gathered from scoping reports, reference design documents interviews with technical experts and government representatives.
