          internal drainage. This stormwater system is shown on amended 360 Civil Consulting Drawing No. 03
          (Rev A)’.



    8.         Provide further information, details and/or amendments to address the following:
                  a. The proposed development requires filling, increases load on the existing drainage
                      pipeline on the site and will limit future opportunities for repair and/or upgrade.
                      Also, there will be an increase in the flows in the pipeline due to the proposed
                      development. As such, it is considered necessary that CCTV investigation of the
                      existing pipeline (from The Cockleshell Street to Thomas Street) be carried out by
                      the applicant determine the condition of the pipeline and report of investigation
                      submitted to Council prior to issuing the OPW approval.
                  b. A drainage easement must be created by the applicant over the subject stormwater
                      pipeline at a width in compliance with Council’s standards and guidelines. Show the
                      required easement on the amended plans.



RESPONSE
Please refer to the Engineering Response to Council’s Information Request (Attachment 3), as well as the
Amended Operational Works Plans prepared by 360 Civil Consulting Pty Ltd (Attachment 2), which responds to
Information Request Items 7 – 9. The specific response to Information Request Item 8 is detailed below:

  a) ‘Please find attached to this response a preliminary stormwater CCTV report for the existing 375mm
     stormwater pipe that runs through 32 The Cockleshell, Noosaville. The CCTV commenced at The
     Cockleshell inlet pit and DrainsKleen have advised that "the survey was abandoned - camera travelled
     downstream about 7m, before reaching, root mass which camera could not pass. Attempted reverse
     survey from other end but unable to access pit."

         The report and photos from DrainsKleen of the root mass is attached for council's information. Further
         clarification from DrainsKleen regarding the reverse survey was sought and the DrainsKleen operator
         who was on site has advised that: -

         "I was unable to locate the downstream pit (unsure if downstream pit exists or is just cut into another
         pipe). I am also unable to go from one of the neighbour pits on Thomas Street as I can't go around
         corners with robot camera due to risk of damaging equipment."

         Since this survey, Council have advised that, in due course, they will unblock the stormwater pipe and
         that no further work by this development is required in order to address this information request item.

         Reviewing the photographs provided in the DrainsKleen report the pipe that is visible appears to be in a
         reasonable condition.

  b) Please refer to the amended 360 Civil Consulting Drawing No. 03 (Rev 3) which details the 4m wide
     drainage easement over the existing council stormwater infrastructure’.



    9.         Provide an engineering plan and longitudinal cross section for the access driveway/s and
               crossovers that include 2.0m wide pathway and demonstrates compliance with IPWEA
