Silt Management

Noting concerns from the public after the initial Environmental Impact Assessment in 2015, plans were modified to reduce the width of the piers and decrease the size of the cargo pier significantly.

The new design of the project has reduced the dredge area and volume. 

The piers have been designed as open structures and therefore do not interfere with sediment transport in any direction, as would occur when solid structures are built close to shore.  

We will use best-in-class management techniques during dredge operations that will keep loose sediments from drifting and moving and to ensure minimal impacts to the surrounding marine environments. These include: 

  • use of silt curtains
  • mechanical excavation to control silt
  • real-time silt level monitoring
