HAZCO has considerable experience completing projects involving work around streams, wetlands and foreshore areas. Execution and remedial work in these sensitive locations requires additional planning and experience for its successful completion. This includes working closely with the various regulating authorities such as those involved in fisheries, port or river authorities and environmental regulatory agencies.

It is often necessary to complete this type of work within specified fishery windows in order to reduce the potential for negative impacts on the existing fish habitat. In order to complete works within intertidal zones, it is necessary to schedule excavations for completion during low tide events. This can involve working night shifts and or double shifts in order to maintain production. Working at low tide can help to improve access, minimize de–watering requirements and help to minimize the amount of silt generated in the water.

Execution of foreshore works typically involves the installation of sediment control measures. These measures can include installation of absorbent booms, aqua dams, silt curtains and in fast moving waters or extremely sensitive areas the installation of sheet pile walls may be necessary.

Restoration of disturbed areas, including replacement of erosion control measures and replacement of riparian zones and/or wetland vegetation can also be a requirement. Completion of any work adjacent to or within a foreshore area requires additional safety and contingency planning. This includes the development and implementation of a site-specific spill response plan along with safe work procedures for working on or near water.
