WHY WE MUST HAVE TUNNELS, NOT CUTTINGS FOR THE BEST BYPASS
LOCAL SCENERY: Coffs Harbour is surrounded by a ‘green cradle’ – the foothills of the Great Dividing Range which wrap around the city. A bypass made with cuttings will destroy our beautiful green backdrop, with cuts of 100m, 180m and 340m having a significant visual impact on the area. The best bypass option – tunnels – will ensure that a significant proportion of this iconic green cradle is saved.
HERITAGE: Cuttings would destroy the cultural significance of the environment and cultural landscape such as waterholes, creeks, plants, bush medicines and animal species. A more thorough heritage report is required to determine cultural heritage sites that may be impacted. It’s believed there are a number of potential archaeological deposits along the proposed corridor.
URBAN GROWTH: Any cutting and land bridge solution will result in significant noise, visual and vibration impacts for the proposed low-density residential growth areas in West Coffs Harbour. As such, Council may need to revise the growth footprint for this area to somewhere else, which may prove challenging with land in short supply.
ENVIRONMENT: Cuttings will have a detrimental impact on fauna – particularly the koala – which is already under considerable stress in the Coffs Harbour area. The proposed land bridges will take years to be built and even longer to be revegetated. Plus, even when the revegetation is fully established, it still won’t provide enough refuge for the koalas.
FLOODING: Using cuttings has serious implications for flood prone areas around Coffs Harbour, particularly North Boambee Valley, with the highway corridor passing through the flood prone land.
ACOUSTIC: There is significant noise implications associated with cuttings, with the bypass route in close proximity to existing dwellings and land zoned for residential development. Expensive noise mitigation measures will have to be put in place for existing homes as well as those planned for construction.
