Slope Stability Report

Subsurface
    Provide filters around all subsurface drainage.
    Provide appropriate drainage behind ALL retaining structures.
    Use flexible pipelines with access for long‐term maintenance.
    Prevent the inflow of surface water.

Waste Water & Storm water

      The site is connected to the mains sewer and storm water systems. All outflows are to be
       directed to these mains.
      Storage tanks should be watertight and adequately founded. Overflows are to be piped to
       the existing storm water system.

7.5 Erosion Control & Landscape
      Control erosion as this may lead to instability.
      Slope protection measures shall be carried out on exposed batters in order to mitigate the
       development of stability and erosion issues. These works shall be carried out in a timely
       fashion after the batter is exposed.
      Re‐vegetate exposed with shrubs, grasses and ground covers preferably with plants
       indigenous to the local area.
