5.3      Western Tributary

It is proposed to reshape the existing western tributary to achieve the following:
      Increase flood storage for the site
      Reduce maintenance requirements for the watercourse
      Reduce habitat for pests species, that is remove breeding ponds for mosquitos and
         toads
      Improve drainage through the site

The proposed works include:
    Reshaping the low flow profile between the top of banks on both sides of the
       watercourse. Drawing Number 1225-33 shows the area of earthworks.
    Placement of a 1.5m wide rock lined invert for the length of the watercourse
    Revegetation of the banks to replace the weeds removed on site
    Maintain existing trees within the riparian zone of the watercourse
