Environmental management


 A Construction Environmental Management Plan (CEMP) has been developed to manage the impact on the environment including:

  • water quality (and stormwater management during construction)
    o    use of sediment ponds to capture site runoff (water then used for dust suppression)
    o    sediment fences and silt socks installed and drainage lines stabilised with grass and rock
  • vegetation removal
    o    accounting for construction impact
    o    protection of the Grey Box woodland near Beach Rd
  • Indigenous and European heritage
    o    protecting and monitoring known heritage buildings and sites
  • construction noise
    o    turning engines off instead of idling
    o    where practical, use mitigation measures on equipment to manage noise
  • air quality, including dust management
    o    using water carts to damp down access roads
    o    limiting construction activities on windy days

Southern Expressway landscaping takes shape in the Field River – May 2014

Following the start of landscaping in the Field River Valley last year, works continued in Autumn 2014 and with recent rain the areas seeded with grass have germinated, turning the hillside a vibrant green.

Landscaping has included areas of open grass with scattered trees and pockets of shrubs as well as mulched batters with a mix of trees and shrubs. Approximately a total of 300,000 trees, shrubs and groundcovers will be planted within the Southern Expressway corridor, with the Field River Valley making up approximately 8%.

Southern Expressway helps community to protect the Sturt River and heritage listed Fairford House at Warriparinga, Bedford Park – October 2013

The Southern Expressway Duplication project team and the City of Marion have worked with the ‘Friends of Warriparinga’ community group to protect a section of the Sturt River from further erosion adjacent the State heritage listed Fairford House (sometimes referred to as Laffer residence), which is one of the last intact examples of an early European settlement and land use surviving within metropolitan Adelaide.

If left unchecked, the river erosion would eventually threaten the stability of Fairford House, located near the Warriparinga Wetlands at Bedford Park.

This section of the river bank is now protected by rock armouring, a solution which was developed in consultation with all stakeholders, with funding provided by the Southern Expressway Duplication project team and the City of Marion. Works were completed by the City of Marion with assistance from the Adelaide Mount Lofty Ranges Natural Resources Management Board.
