  At the time of the inspection the existing 21 slope exhibited no evidence of failure, rotation
  or sliding or cracking. No areas of groundwater seepage were observed. Surface erosion was
  observed to be minimal.
  The proposed Slope is to be modified provide a level building pad.
  The existing slope will be cut back by approximately 8m at an angle of 80 to a maximum
  height of 2.6m; any clay at the crest of the cutting will be cut back to 4h to 1v and will be
  topsoiled and seeded to protect from erosion. Long term the slope will be
