  nor is it reasonable in the circumstances to require an easement over the relocated sewer
  within the Telstra Depot land (Lot 5).

  With respect to the further issues raised in the email of 17 January 2018, the following
  comments are provided.

  Issue
  Specific outcome O1 requires that downstream properties are not adversely impacted by the
  development.

  Drawing 15652-SK1 shows the Bioretention basin will extend right up to the property boundary
  with the invert level from the outlet pipe at RL4.7. Given that this is below the surface level of the
  adjoining property, it is expected that the applicant is proposing to include scour protection as
  well as stormwater infrastructure in the form of the outlet pipe within the adjoining property.

  Info Required
  Demonstrate that all infrastructure, including scour protection for the overflow weir along with
  the low flow pipe will be able to be contained entirely within the applicant’s property.

  With respect to the above, the following advice has been provided from TOD Consulting:

  The sections X and Y on drawing 15652-SK1 are probably a little misleading with respect to the
  existing ground levels. In reality the ground levels along the wall adjacent to the boundary vary
  from RL 5.2 to RL 4.7. The level contours in the neighbouring property indicate that the existing
  surface level adjacent to rock rubble dissipater is at or below RL 4.7. As shown on section X the
  weir for the bio basin is located at the western end of the basin and discharges water onto the
  rock rubble dissipater. Water for the rock rubble dissipater sheet flows into the neighbouring
  property (park).

  It is noted that the previous approval over the land for the multi-level carpark structure and
  the subsequent operational works approval (Attachment 2) allowed for the construction of
  the stormwater retention basin in the same location. The proposed retention basin is
  essentially the same design as that previously approved.

  Issue
  Specific Outcome O8 of the Water Sensitive Design Code of the Noosa Plan requires that the
  scale of the development provides adequate footprint to integrate all elements of the stormwater
  quality treatment infrastructure including maintenance access without the need for retaining
  walls.

  Info Required
  Demonstrate how the design of the proposed bioretention basin is consistent with the Water by
  Design Bio-Retention Technical Design Guideline (the acceptable solution for Specific Outcome
  O8) in terms of:
