PRECINCT F & E2 NOOSA SPRINGS DEVELOPMENT



          Site is approximately 50% in alignment with the design assumptions in the Noosa Springs
          Master Drainage Plan. Therefore it is not considered that the subject Site will have a
          material impact on residence times. Further information has previously been provided to
          Council by Morgan Consulting Engineers in the form of a stormwater quantity assessment
          letter dated 20/09/2017 (Clause 49 - Part 2a).

          Due to the limitations of the MUSIC modelling software it is not possible to quantify the
          level of treatment achieved for infiltrating runoff and therefore it cannot be determined
          whether the SPP targets have been met (Clause 49 - Part 2b).

          The site discharges to an enclosed stormwater system which discharges to the Noosa
          Springs Lake System as opposed to an open drain or non-tidal waterway. The Noosa
          Springs Golf Course Lake System was originally designed and constructed to cater for the
          Noosa Springs resort flows and therefore considerations for frequent flow objectives (no
          increase in 1 year ARI peak stormwater flows) are not deemed necessary. (Clause 47 -
          Part a).
